Description

Level and technical field

The present invention relates generally to methods for adaptively optimizing power dissipation and transmission power at a power source of a communication device. More specifically, the present invention relates to methods for adaptively optimizing power dissipation and transmission power from a power source received internally of a communication device. In particular, the present invention relates to methods for adaptively optimizing power dissipation or adaptively optimizing transmit power of an internally received Event Marker (IEM) (or combination thereof), which acts as a galvanic power source, such as a battery, when dissolving dissimilar materials under the action of a conductive fluid medium. After power is applied as described in the invention, the IEM transmits a broadcast signal, as described in more detail below. Accordingly, it may be desirable to optimize signal transmission throughout the IEM broadcast cycle, while minimizing battery drain. It may be further desirable to optimize signal transmission by adjusting the combination of the consumed battery current and the duration of the transmission pulse over the broadcast cycle and balancing the output charge with respect to a given recovery battery voltage or measured battery impedance.

The present invention also relates generally to a device, system and method for determining the availability of battery power before the communication device received inside the device is in a high current consumption mode. To ensure the operation of an inwardly received device, such as IEM, whose battery impedance is determined by the degree of dissolution of the material over time and can vary by ten or more times, it may be desirable to know before broadcast that the battery is capable of providing a given current consumption.

The present invention also relates generally to an integrated circuit device, system and method using a substrate as a negative terminal. In devices based on complementary metal oxide semiconductors (CMOS) using p-type starting material, their substrate is often selected in accordance with the largest negative potential of the system. In the case of an ingested device, such as IEM, the output of this substrate forms a negative terminal of the power source, and the top of the semiconductor wafer is connected to the positive terminal of the power source. With this configuration, it may be difficult to bring the negative terminal to the top side of the plate due to a possible short circuit of the positive terminal during the actuation of the power supply or increase of the leakage current between the two terminals. Due to the difficulty of outputting the negative terminal to the upper side of the plate and using only the output of the substrate, measurement errors may occur when checking the plate due to the impedance between the substrate and the integrated circuits that are connected to the negative terminal. Accordingly, it may be desirable to output a negative terminal that can be located on the upper side of the plate, actuating only in test modes and being in a high impedance state in all other operating modes.

The present invention also relates generally to a device, system, and method for separating a power source and a transmission power source in an internally received device such as IEM. In a standard architecture, the IEM power supply is shared by digital circuits, analog circuits, and I / O circuits. This requires additional circuits to disconnect the common power source of the analog and / or digital circuits before transmitting so as not to affect their operation and save enough charge in the charge storage to ensure the operability of the analog and digital circuits while disconnected from them source of power. Accordingly, a method may be desirable to physically separate the IEM power supply into a plurality of power supplies of a predetermined magnitude and to dispense with a charge storage device. In addition, it may be desirable to create an architecture to reduce the susceptibility of digital and analog circuits to the effect of the relationship, which may occur due to the close proximity of power sources to each other.

SUMMARY OF THE INVENTION

According to one of the features, a method for stabilizing the voltage of a battery with optimization of the power supplied to the receiver during transmission of a broadcast packet is proposed. The method includes receiving, by a logic circuit, a broadcast packet containing a predetermined number of bits for transmission by a controller to a receiver located at a distance from the controller; determining, by the logic circuit, the number of cycles in which the sample battery voltage is greater than or equal to or less than the nominal battery voltage during the first subset of the specified number of bits of the broadcast packet; and performing an up or down adjustment procedure based on the counted number of cycles when the selected battery voltage is not equal to the nominal battery voltage in more than half the total number of counted cycles.

Embodiment 1

According to one aspect, the present invention generally provides a device, system and method for adaptively optimizing power dissipation and transmission power from a power source, such as a battery, a communication device. More specifically, according to one of the features of the present invention, a device, system and method for adaptively optimizing power dissipation and transmission power from a power source received inside the communication device. More specifically, according to yet another aspect, the present invention provides an apparatus, system and method for adaptively optimizing power dissipation and transmission power of a battery, for example, IEM.

According to one of the features of the methods of adaptive optimization of power dissipation and transmission power at a power source, such as a battery, communication devices can be implemented using the decision logic of automatic calibration of adaptive optimization of power dissipation and transmission power at a battery using up and down adjustment procedures. In accordance with the present invention, the decisive logic of automatic calibration, including the up and down adjustment procedures for adaptive optimization of power dissipation and transmission power of a battery, can be implemented in a system containing IEM. IEM features are described in US Pat. No. 7,978,064 to Zdeblick et al. Entitled “Communication System with Partial Power Source,” which is incorporated herein by reference in its entirety.

Before describing the various features of the decision logic of automatic calibration and the up / down adjustment procedures for adaptive optimization of power dissipation and transmission power, the battery will briefly describe the system in which the decision logic of automatic calibration and the up / down adjustment adaptive optimization of power dissipation and transmission power can be implemented at the battery.

Accordingly, in FIG. 1 is a block diagram illustrating one of the features of an event indication system 100, at the opposite ends of which are heterogeneous metals. According to one of the features of the system 100 can be used in combination with any pharmaceutical products. According to one aspect, the system can be used to determine when a patient is taking pharmaceutical products, such as, but not limited to, a pill, tablet or capsule. However, the scope of the present invention is not limited by the conditions and products that are used with the system 100. For example, the system 100 can be placed on a tablet or capsule and placed in a conductive fluid medium. Then the tablet or capsule dissolves over time and releases the system 100 into a conductive fluid medium. Accordingly, according to one aspect, a tablet or capsule may comprise a system 100 without a drug substance or preparation. Such a capsule, for example, can be used in any conditions in which a conductive fluid medium is present, and with any product, such as, without limitation, an active drug substance, vitamin, placebo. In various examples, the capsule or tablet may be placed in a container filled with jet fuel, salt water, tomato sauce, motor oil, or any similar substance. In addition, the capsule containing the system 100 can be swallowed simultaneously with pharmaceutical products in order to register the occurrence of an event, such as the time of receipt of the product, or in order to initiate any other event.

In a specific example of a system 100 in combination with pharmaceutical products, system 100 is activated by ingestion of a product or pill. System 100 monitors conductivity and generates a unique current signature, the detection of which means that pharmaceutical products have been ingested. The system 100 comprises a chassis 102. The chassis 102 serves as a chassis for the system 100, and a plurality of components are secured, placed, or mounted thereon. The first substance 104, which is ingested, is physically connected with the frame 102 of the system 100. The substance 104 can be chemically deposited, sprayed or build up on the frame, which in all cases can be called "deposition" in relation to the frame 102. The substance 104 is deposited on one side of the frame 102. The substances, which can be used as substance 104 include, without limitation, Cu or CuI. Substance 104 is precipitated by vapor condensation, electrodeposition or plasma deposition, among other methods. The layer of material 104 may have a thickness of from about 0.05 microns to about 500 microns, such as from about 5 microns to about 100 microns. Its shape is regulated by deposition with a shadow mask or photolithography and etching. In addition, although only one region for deposition of a substance is shown, each system 100 may comprise two or more electrically unique regions onto which a substance 104 may be deposited, if desired.

On the other hand, which may be the opposite side, as shown in FIG. 1, the ingested second substance 106 is deposited, that is, the substances 104 and 106 are not the same. Although not shown, the other selected side may be the side next to the side selected for the substance 104. The scope of the present invention is not limited to the selected side, and the term “other side” may mean any of a plurality of sides different from the first selected side. In addition, although it is shown that the system has a square shape, it can have any geometrically acceptable shape. The first and second substances 104, 106 are selected so as to create a potential difference upon contact of the system 100 with a conductive fluid medium, such as body fluids. Substances used as substance 106 include, but are not limited to, Mg, Zn, or other electronegative metals. As indicated above with respect to the first substance 104, the second substance 106 can be chemically deposited, sprayed, fixed, or build up on the frame. In addition, an adhesive layer may be needed to help the second material 106 (and also, if necessary, the first material 104) adhere to the frame 102. Typical adhesive layers for the second material 106 contain Ti, TiW, Cr or the like. The anode layer and the adhesive layer can be deposited by condensation from the vapor phase, electrodeposition or plasma deposition. The layer of the second substance 106 may have a thickness of from about 0.05 microns to about 500 microns, such as from about 5 microns to about 100 microns. However, the scope of the present invention is not limited either by the thickness of the layers of any substances, nor by the type of process used to deposit or fix the substances on the frame 102.

According to the invention, the substances 104, 106 can be any pair of substances with different electrochemical potentials. In addition, in embodiments where the system 100 is used on a living organism, the substances 104, 106 may be vitamins that can be absorbed. More specifically, the substances 104, 106 may be any two substances applicable under the conditions in which the system 100 operates. For example, when used with the internally produced products, the substances 104, 106 are any pair of ingested substances with different electrochemical potentials. One illustrative example is when the system 100 is in contact with an ionic solution, such as an acidic stomach. Applicable substances are not limited to metals, and in some embodiments, pairs of substances from metals and non-metals are selected, for example, a pair of metal (such as Mg) and salts (such as CuCl or CuI). As for the active electrode substances, any pairs of substances formed by metals, salts or intercalated compounds with correspondingly different electrochemical potentials (voltage) and low resistance of the transition layer are applicable.

Applicable substances and their vapors include, without limitation, the substances from Table 1 below. According to one of the features, one or both metals can be alloyed with non-metal, for example, to enhance the created potential difference of substances when they come into contact with a conductive fluid medium. Non-metals that can be used as alloying impurities in some embodiments include, without limitation, sulfur, iodine, etc. In another embodiment, the anode material is copper iodide (CuI) and the cathode material is magnesium (Mg). According to the features of the present invention, electrode materials that are harmless to the human body are used.

Accordingly, upon contact of the system 100 with a conductive fluid medium between the first and second substance 104, 106, a current path is formed by the conductive fluid medium. A controller 108 is attached to the chassis 102, electrically connected to the first and second substances 104, 106. The controller 108 contains electronic circuits, for example, control logic circuits, which are capable of regulating and changing the conductivity between substances 104, 106.

The created potential difference of the first and second substances 104, 106 provides energy for the operation of the system 100, also creates an electric current through a conductive fluid medium and the system. According to one of the features of the system 100 operates in direct current mode. Alternatively, the system 100 adjusts the direction of the current and cyclically reverses it, similar to alternating current. When the system 100 reaches a conductive fluid or electrolyte, which is a physiological fluid, such as an acidic stomach, the path of the electric current between substances 104, 106 is closed outside the system 100; in this case, the controller 108 controls the current path through the system 100. The closure of the current path ensures the flow of current, and in turn, the receiver 304 (shown in Fig. 3) can detect the presence of current and receive information transmitted / emitted by the system 100. According to one of the features of the receiver recognizes that system 100 is activated, and a desired event occurs or has occurred.

According to one aspect, both substances 104, 106 may have functions similar to those of both electrodes required for a DC power source, such as a battery. A conductive fluid medium acts as an electrolyte needed to replenish the power source. The described replenishment of the power source is determined by the physicochemical reaction between the substances 104, 106 of the system 100 and the surrounding body fluids. A replenished power source can be considered a power source that uses reverse electrolysis in an ionic or conductive solution, such as gastric juice, blood or other body fluids and some tissues. In addition, the medium may be anything other than the environment of the body, and the liquid may be any conductive fluid medium. For example, the conductive fluid may be salt water or metallic paint.

According to some features, both substances 104, 106 can be protected from the environment by an additional layer of substance. Accordingly, when the protective layer dissolves and two different materials 104, 106 are exposed to the target area, a potential difference is generated.

According to some features, the replenished power source is a power source consisting of active electrode substances, electrolytes and inactive substances such as current collectors, packages, etc. Active substances is any pair of substances with different electrochemical potentials. Applicable substances are not limited to metals, and in some embodiments, pairs of substances from metals and non-metals are selected, for example, a pair of metal (such as Mg) and salts (such as CuI). As for the active electrode substances, any pairs of substances formed by metals, salts or intercalated compounds with correspondingly different electrochemical potentials (voltage) and low resistance of the transition layer are applicable.

As the substances forming the electrodes, many different substances can be used. According to some features, the electrode materials are selected so that when in contact with the target physiological site, for example, the stomach, to provide a voltage sufficient to actuate the identifier system. In some embodiments, the voltage provided by the electrode material when the metals of the power source are in contact with the physiological target is 0.001 volts or more, including 0.01 volts or more, in particular 0.1 volts or more, for example 0.3 volts or more, in particular 0.5 volts or more, including 1.0 volts or more, in some embodiments, the voltage is from about 0.001 volts to about 10 volts, in particular from about 0.01 volts to about 10 volts .

The first and second substances 104, 106 provide a potential difference for activating the control device 108. After activating or turning on the control device 108, it can uniquely change the conductivity between the substances 104, 106. By changing the conductivity between the substances 104, 106, the control device 108 is able to control the magnitude and duty cycle of the current through the conductive fluid medium that surrounds the system 100. a unique current signature that can be detected and measured by the receiver 304 (shown in FIG. 3), which can be inside or outside the body. System 100 can transmit information in the form of packets as long as the first and second substances provide a power source. In addition to regulating the magnitude of the current path between the substances, non-conductive materials, a membrane, or a "skirt" are used to increase the "length" of the current path and, therefore, to increase the conductive path, as described in patent application US 12/238345 entitled "In-Body Device with Virtual Dipole Signal Amplification "filed September 25, 2008, the contents of which are incorporated by reference in their entirety into this application. Alternatively, the terms “non-conductive material”, “membrane” and “skirt” are used interchangeably with the term “current path extender” without affecting the scope of the embodiments and claims. Skirt elements 105, 107 may be associated with the frame 102, for example, attached to it. Various forms and configurations of a skirt are within the scope of the present invention. For example, the system 100 may be completely or partially surrounded by a skirt, which may extend along the central axis of the system 100 or with an offset relative to the central axis. Accordingly, the scope of the claimed invention is not limited by the shape or size of the skirt. In addition, in other embodiments, the first and second substances 104, 106 can be separated by a single skirt, which is located in any given area between the substances 104, 106.

In FIG. 2 is a block diagram illustrating a controller 108. The controller 108 comprises a control module 202, a counter or a clock generator 204, a memory 206, and a logic circuit 208. In addition, the controller 108 may include one or more sensor modules. The control module 202 has an input 210 electrically connected to the first substance 104 and an output 212 electrically connected to the second substance 106. The control module 202, a clock pulse generator 204, a memory 206, and a logic circuit 208 (and optionally sensor modules) also have power inputs (some of which are not shown). The power of each of these components is provided by the potential difference that is created during the chemical reaction of the first and second substances 104, 106 with a conductive fluid medium when the system 100 contacts a conductive fluid medium. The control unit 202 controls the conductivity through a logic circuit that changes the impedance of the system 100. The control unit 202 is electrically coupled to a clock pulse generator 204. A clock pulse generator 204 provides a clock cycle for the control module 202. The control unit 202 changes the conductivity characteristics between the first and second substance 104, 106 at the end of the set number of synchronization cycles, based on the characteristics programmed therein. This cycle repeats and thereby the controller 108 creates a characteristic of a unique current signature. The control module 202 is also electrically connected to the memory 206. The power of both the clock generator 204 and the memory 206 is provided by the potential difference created by the first and second substances 104, 106.

As shown in FIG. 3, according to one aspect, a logic circuit 208 is provided for monitoring current consumption and impedance of a power source or battery formed between the first and second substances when the system immerses an ionic fluid medium. According to one of the features of the logic circuit 208, containing a sampling circuit with memory frequency and analog-to-digital Converter (ADC), is configured as an algorithm or automatic calibration process for the adaptive optimization of power dissipation and transmit power at the power source. According to one of the features and, as described in more detail below, the logic circuit 208 monitors and regulates the pulse duration and the limit value of the current at the output of the system 100 in order to stabilize the battery voltage and the duty cycle of the transmitted signal with optimization of the power supplied to the receiver 304 (shown in FIG. 3). According to one of the features, an algorithm for sampling the voltage value (V _BATT ) of the battery during transmission of a given data packet can be implemented. According to one of the features during the transmission of the subsequent packet, in particular, for example, during the transmission of the next data packet, the pulse width and / or current limit can be adjusted. Algorithm settings (initial pulse duration, minimum and maximum current limits) can be programmed in memory 206, such as, for example, non-volatile memory. This programming step may be performed, for example, at the plate verification stage. In operation, the logic circuit 208 may perform an up or down adjustment procedure depending on the state of the recovery voltage and the battery impedance. Logic 208, including up and down adjustment procedures, is described in more detail below with reference to FIG. 5-7. Logic 208 may be implemented in hardware, software, or a combination thereof. According to one of the features, the logic circuit 208 can be implemented as a processor, a state machine, a digital signal processor, discrete logic, among other implementations, well known to specialists in this field of technology. According to one feature, the logic circuit 208 may be embodied in a specialized integrated circuit (ASIC). Accordingly, the term “algorithm” or “procedure” need not be understood as the execution of computer instructions. According to one of the features of the power supply of the logic circuit 208 is provided by the potential difference created by the first and second substances 104, 106.

In FIG. 3 is a block diagram illustrating one of the features of a communication system 300 in which an event indicating system 100 communicates with a receiver 304

on channel 308 communication. It should be noted that the communication channel 308 may, without limitation, be an electric current generated by ion emission or a wireless communication channel. According to one feature, the logic circuitry 208 is connected to a battery 302 serving as a power source, modeled as a voltage source (V _BATT ) with an internal impedance (Z _BATT ) and an output current (i). Logic 208 controls the output current (i) of the battery 302 and the impedance (Z _BATT ) of the battery 302. According to one aspect, the battery 302 is formed when the first and second substances 104, 106 are immersed in an ionic fluid, as described with reference to FIG. 1 and 2. The features of receiver 304 are described in US Pat. No. 8,114,021 to Robertson et al. Under the name "Body-associated Receiver and Method", which is hereby incorporated by reference in its entirety.

According to one feature, the logic circuit 208 is configured to perform an algorithm or an automatic calibration process to adaptively optimize power dissipation and transmit power of the event indication system 100. According to one aspect, the controller 202 of the event indicating system 100 transmits a broadcast signal 306 to the receiver 304. The broadcast signal 306 consists of a train of pulses transmitted at a given frequency (f). The individual pulses of the broadcast signal 306 form a unit of information, and the pulse train forms a data packet. Pulses have a follow-up period (T) and a duration (w), during which the output signal is active. The inverse of the period (T) of the pulse repetition is the frequency of the broadcast signal 306. The transmission of pulses can be carried out with a given duty cycle, which is defined as the ratio of the duration (w) and (T) of the pulse repetition.

f = 1 / T Hz

Duty Cycle = w / T

In one aspect, the controller 202 may transmit a broadcast signal 306 containing a first data packet that contains a predetermined number m pulses (e.g., m information units) at a first frequency f ₁ . According to one aspect, the controller 202 may transmit a plurality of first packets containing a predetermined number of bits at a first frequency f ₁ . Later, the controller 202 may begin broadcasting a second data packet that contains a predetermined number n pulses (e.g., n information units) at a second frequency f ₂ . According to one aspect, a series of first packets at frequency f ₁ is transmitted to receiver 304 with sufficient power to activate receiver 304. Actual data or information regarding the event display system 100 is transmitted through a second series of packets at frequency f ₂ . Accordingly, after the receiver 304 detects the first packets, it prepares to receive data transmitted by the second packets.

The first frequency f ₁ may be any given frequency, according to one of the features any frequency from about 10 kHz to about 30 kHz, more preferably about 20 kHz. The second frequency f ₂ can be any given frequency, according to one of the features any frequency from about 10 kHz to about 15 kHz, more preferably about 12½ kHz.

According to one aspect, the event indicating system 100 may broadcast a predetermined number of packets, for example, from 3 to 6 packets or more, at a first frequency f ₁ with a time delay between packet transmission c at a first frequency f ₁ and a second frequency f ₂ or by changing the time interval between packets to avoid transmission conflicts. Similarly, according to one aspect, the event indicating system 100 may broadcast a predetermined number of packets, for example, from 3 to 6 packets or more, at a second frequency f ₂ in order to avoid transmission conflicts. However, it should be noted that the number of repeated packet transmissions at the first frequency f ₁ or the second frequency f ₂ can be determined statistically based on the number of event indication systems 100 received internally by the patient.

According to one feature, as described in more detail below, the logic circuit 208 monitors and controls the pulse width (w) at the output of the controller 202 and the limit value (i) of the current of the broadcast signal 306 generated by the event indicating system 100 to stabilize the battery voltage (V _BATT ) and a duty cycle of pulses of the broadcast signal 306, with optimization of the power supplied to the receiver 304. According to one of the features, the logic circuit is configured to sample the voltage (V _BATT ) of the battery during broadcast the transmission of a given data packet by the controller 202. According to one of the features for the current transmitted packet, the adjustment of the pulse duration (w) and / or current limit value (i), which can be applied to the subsequent packet, for example, during broadcasting of the next data packet, can be determined . Algorithm settings, such as, for example, the initial pulse width (w ₀ ), minimum (i _min ) and maximum (i _max ) current limit values, can be programmed in memory 206 (Fig. 2), such as, for example, non-volatile memory. This programming step may be performed, for example, at the plate verification stage.

According to one of the features, the minimum current i _min is about 1 mA, and the maximum current i _max is about 4 mA. According to one of the features, the minimum duty cycle of DC _min is about 15%, and the maximum duty cycle of DC _max is about 50%. These values are only examples, the context of which should not be limited to the system.

In operation, the logic circuit 208 may perform an up or down adjustment procedure depending on the state of the recovering voltage (V _BATT ) 302 and the impedance (Z _BATT ) of the battery. Logic 208, including up and down adjustment procedures, is described in more detail below with reference to FIG. 5-7.

Logic 208 may be implemented in hardware, software, or a combination thereof. According to one aspect, logic 208 may be implemented as a processor, digital signal processor, discrete logic, or state machine, among other implementations well known to those skilled in the art. According to one feature, the logic circuit 208 may be embodied in a specialized integrated circuit (ASIC). Accordingly, the term “algorithm” or “procedure” need not be understood as the execution of computer instructions.

Although, according to the features illustrated with reference to FIG. 1-3, logic 208 is described in connection with adaptive optimization of power dissipation and transmission power of a power source created between the first and second substances 104 and 106, logic 208 is not limited to this context. For example, logic 208 may be configured to adaptively optimize power dissipation and transmit power from any power source, such as a conventional battery.

At receiver 304, a module with alert functionality may also be used. According to various aspects, one or more of the following can be used in the alarm switching module: the alarm awakening module, the warning module, the wave / frequency module, the multi-frequency module, and the modulated signal module.

The alarm switching module may be associated with the transmission of warning signals, for example, with a channel for transmitting warning signals, a protocol for transmitting warning signals, etc. In the context of the present description, warning signals are typically signals transmitted by the controller 108 as part of a message or in addition to a message. Warning signals can have clearly defined characteristics, such as frequency. Alarms can be easily detected in noisy environments and can be used to trigger a tracking circuit, such as described below.

According to one of the features of the module switching alarm signals may be an awakening module of warning signals with awakening functionality. Awakening functionality is usually the functionality of working in high power modes only for specific periods of time, for example, short periods for specific purposes of receiving a signal, etc. One of the important requirements for the receiving part of the system is its low power. In the case of an implanted receiver, this property can be beneficial to provide both small size and long-term battery power. The alarm switching module provides these benefits by forcing the receiver to operate in high power mode for very limited periods of time. Short duty cycles of this kind are able to provide the optimal system size and energy consumption properties.

In practice, the receiver 304 may periodically “wake up” and perform a “tracking function” in a low-power mode by, for example, a tracking circuit. It is during this period that the receiver 304 detects the first packet at the first frequency f ₁ . In the context of the present invention, the term "tracking function" generally means a short-term low-power function, which allows to determine whether a transmitter is present, for example, a communication system 100. If the tracking function detects a broadcast signal 306 of the communication system 100, the receiver 304 may transition to a higher power-consuming communication decoding mode. If there is no broadcast signal 306 of the communication system 100, the receiver 304 may return, for example, immediately return to standby mode. This method conserves energy for relatively long periods of absence of the transmitter signal, while the possibility of efficient operations in decoding mode with higher power consumption for a relatively small number of periods of the presence of the broadcast signal 306 remains available. Several modes and their combination can be available for tracking schemes . By matching the needs of a particular system with the configuration of a tracking circuit, system optimization can be achieved.

In FIG. 4A is a diagram 400 illustrating a warning switching module with a longer tracking period 401 than a broadcast period 303 of a broadcast signal 306 (FIG. 3). The horizontal axis represents the time function. As shown, the broadcast signal 306 is periodically repeated with a repetition period 403, while the tracking function also operates. As such, in practice, the tracking period 401 may exceed the repetition period 403 of the broadcast signal 306. According to various aspects, the tracking periods can be separated by a relatively long period of time. In this way, it is guaranteed that whenever a tracking function, for example, implemented as a tracking circuit, is operational, at least one transmission occurs.

In FIG. 4B is a diagram 400 illustrating a warning switching module with a short but frequent tracking period 405 and a long transmitted packet 407. A tracking circuit is activated at a certain point during transmission. In this way, the tracking circuitry can detect the transmitted signal and go into high power decoding mode.

One of the additional features of activation of warning signals is the provision of the "tracking" function in continuous mode. In this feature of the alarm channel, the fact that the total energy consumption is equal to the product of the average power consumption and time can be used. According to this feature, the system can minimize the total energy consumption due to very short periods of activity, in which case the average number of periods of activity is reduced to a small amount. Alternatively, continuous tracking with low activity is provided. In this case, the configuration provides a low power sufficient for continuous operation of the receiver with a total energy consumption at an acceptable level for the parameters of a particular system.

According to one aspect, the receiver tracking module 304 is configured to scan data encoded by the controller 202 in an electric current that generates ion emission. Receiver 304 receives data in the form of a conductivity signal according to a set schedule, for example, every 20 seconds. The active tracking period is limited, for example 300 ms. This relatively low power cycle provides features with lower average power consumption and longer system life. The receiver 304 determines whether a broadcast signal 306 is present and whether this broadcast signal 306 has a valid identifier. If a signal with a valid identifier is not detected during the active tracking period, the active analysis is turned off until the next specified activity period. If a broadcast signal 306 having a valid identifier is received, the receiver 304 determines whether a signal 306 is received from a previously detected ion emitter. If broadcast signal 306 is received from a previously detected ionic emitter, receiver 304 determines whether the metric calculated by the threshold counter (in other words, exceeds the number of separate valid detections of the same identifier) during the current activation cycle (a given time since the last valid identifier was detected such as 10 minutes). If the metric exceeds this threshold determined by the threshold counter, the receiver 304 returns to the tracking mode. If the indicator does not exceed the threshold value, the receiver operates in a 100% detection mode in order to analyze the received data encoded in electric current by ion emission. After the received data is decoded and analyzed, the receiver 304 determines that the data encoded in the electric current comes from a reliable source that is different from the previously detected source, after which the threshold counter is set to zero.

According to another feature, the incoming broadcast signal 306 received by the receiver 304 displays the signals that are received by the electrodes, undergo bandpass filtering (such as in the 10-34 kHz band) by a high-frequency signaling circuit (which includes the carrier frequency), and are converted from analog to digital. Then, broadcast signal 306 is decimated and mixed at a nominal excitation frequency (such as 12.5 kHz, 20 kHz, etc.) in the mixer. The resulting signal is subjected to decimation and low-pass filtering (such as with a bandwidth of 5 kHz) in order to obtain a carrier signal mixed into a signal with a carrier shift. The carrier-shifted signal is further processed (by quickly converting the Fourier transform and then detecting the two largest peaks) in order to obtain the true carrier signal. This protocol provides an accurate definition of the carrier frequency of transmitted warning signals.

Following the description with reference to FIG. 1-4, containing an internally received device of a common system 100, in which a device, system and method for adaptively optimizing power dissipation and transmission power of a battery 302 can be described, a flowchart will be described illustrating one of the features of the automatic calibration decision logic 500 shown in FIG. 5. The automatic calibration decision logic 500 may be implemented by the logic circuit 208. Accordingly, the automatic calibration decision logic 500 is described with reference to FIG. 1-5. During the broadcast cycle of the communication system 100, it is desirable to optimize the broadcast signal 306 while minimizing the charge removed from the battery 302 using one of the features of the procedure illustrated in FIG. 5. Broadcast signal 306 can be optimized by adjusting the combination of current (i) and pulse width (w) during the broadcast cycle and balancing the output charge with respect to the measured predefined recovery voltage (V _BATT-REC ) or impedance (Z _BATT ) of battery 302 .

According to one aspect, this can be achieved by a process or algorithm of "up-regulation" and "down-adjustment", as described with reference to FIG. 6 and 7. In the up-regulation phase, the current (i) or duration (w) of the broadcast cycle pulse is increased until a predetermined recovery voltage (V _BATT-REC ) or impedance (Z _BATT ) of the battery 302 is reached. Then this value is increased by one, to ensure that the voltage (V _BATT ) of the battery 302 exceeds the recovery voltage (V _BATT-REC ) of the battery 302. Then, the “down adjustment” phase occurs when another parameter, i.e. the current (i) or duration (w) of the pulse of the broadcast cycle decreases by detecting once again the predetermined recovering voltage (V _BATT-REC ) or the impedance (Z _BATT ) of the battery 302. Then this combination of current (i) and the duration (w) of the pulse is stored in memory and used during one broadcast cycle when transmitting a subsequent packet, for example, the next packet.

According to one aspect, the determination of the recovery voltage (V _BATT-REC ) or the impedance (Z _BATT ) of the battery 302 is performed by sampling the recovering voltage (V _BATT-REC ) of the battery 302 during a non-broadcast cycle and calculating its average value. In addition, in the optimization process, the initial value of the current (i) and duration (w) of the pulse, as well as the maximum value of current (i) and duration (w) of the pulse can be used to exclude violation of the minimum and maximum broadcast parameters.

During the traditional transmission of the broadcast signal 306, the entire power of the battery 302 is used by essentially shorting the battery 302. This leads to an increase in recovery time and an increase in the discharge rate of the battery 302. According to one feature, the automatic calibration decision logic 500 provides a method for adaptively optimizing power dissipation and transmit power in order to extend the life of the battery 302 while providing sufficient transmit power for appropriate detection of the controller 202 by the receiver 3 04. According to one of the features, the automatic calibration decision logic 500 may be implemented by the logic circuit 208. Accordingly, consider with reference to FIG. 5 one of the features of the decision logic 500 is automatic calibration. According to one aspect, the automatic calibration decision logic 500 can be used to adjust the pulse width (w) and current limit value (i) of the broadcast signal 306 transmitted by the controller 202 to stabilize the battery voltage (V _BATT ) and the broadcast signal duty cycle 306, with optimization the power supplied to the receiver 304. According to one of the features, the logic circuit 500 selects a value (V _BATT ) during transmission of a data packet. According to one of the features of the transmission of the data packet may be the transmission of the data packet at a frequency of 20 kHz. The duration (w) of the pulse and / or the limit value (i) of the current are adjusted starting from a subsequent data packet, such as, for example, another data packet. According to one of the features, the settings of the logic circuit 500 (initial pulse duration, minimum and maximum current limits) can be programmed in non-volatile memory 206 (Fig. 2) when checking the plate.

As shown in FIG. 3-5, in step 502, the auto calibration calibration logic 500, for example, logic 208 awaits the next available broadcast packet to characterize the battery voltage (V _BATT ) and battery impedance (Z _BATT ). At decision block 504, logic 208 determines whether the last broadcast packet is in the transmit queue. If this is not the case, the logic 500 continues along the No branch, and the logic 500 waits for the last packet. If so, the execution of logic 500 continues along the Yes branch. At step 506, the logic circuit 208 samples the voltage (V _BATT ) of the battery 302 and counts using a counter, for example, the number of cycles in which the sample battery voltage (V _CAP ) is less than the nominal battery voltage (V _{BATT_NOM} ), for example, V _CAP <V _{BATT_NOM} , from the i-bit to the j-bit of the broadcast packet. At decision block 508, logic 208 determines whether the sampled voltage (V _CAP ) is less than the rated voltage (V _{BATT_NOM} ) of the battery in more than half the cycle from the i-bit to the j-bit of the broadcast packet. The sample voltage (V _CAP ) of the battery may be determined by logic 208 using, for example, a frequency memory and ADC sampling circuit, such as, for example, a frequency memory sampling circuit 808 and an analog-to-digital converter 812 described with reference to FIG. 8. Accordingly, according to one of the features, the logic circuit 208 may be configured to use an internal or external sampling circuit with memory frequency and circuits of the analog-to-digital Converter for sampling the battery voltage.

When the sample voltage (V _CAP ) is less than the rated voltage (V _{BATT_NOM} ) of the battery for more than half the cycle from the i-bit to the j-bit of the broadcast packet, logic 500 continues along the Yes path to process 700 down adjustment ", which is described with reference to FIG. 7. In short, during the down-adjustment process 700, the current (i) or pulse width (w) of the broadcast cycle decreases until it detects once again the set recovery voltage (V _BATT-REC ) or impedance (Z _BATT ) of the battery 302.

When the sample voltage (V _CAP ) is less than the rated voltage (V _{BATT_NOM} ) of the battery in less than half the cycle from the i-bit to the j-bit of the broadcast packet, the logic 500 continues along the No branch to acceptance step 510 solutions to determine the operating mode.

According to one aspect, the logic circuit 500 may be configured to operate in multi-cycle X-bit mode or single-cycle Y-bit mode. When operating in multi-cycle X-bit mode in step 512, logic 208 counts the number of cycles in which the sample voltage is less than the nominal battery voltage, for example, V _CAP <V _{BAT_NOM} , from a (j + 1) -fold bit to k- multiple bits. Otherwise, at step 514, logic 208 counts the number of cycles in which V _CAP <V _{BAT_NOM is} from a (k + 1) -fold bit to a 1-fold bit. After counting such a number of cycles in decision step 516, the logic circuit 500 determines whether the sample voltage V _{CAP is} greater than the nominal voltage (V _{BATT_NOM} ) of the battery, for example, V _CAP <V _{BAT_NOM} , in more than half the cycles. When the sample voltage (V _CAP ) is not greater than the rated voltage (V _{BATT_NOM} ) of the battery, for example, V _CAP <V _{BAT_NOM} , in more than half the cycles, the logic continues along the "No" branch until step 502, where the logic the circuit expects a new broadcast packet, the process starts anew.

Accordingly, during a process 500, a predetermined limit is determined within which the battery 302 should operate. For example, in one example, provided that the voltage of the battery 302 is about 1 volt and restored to about 1 volt, it is likely that the system 300 is operating within design parameters. To change both the current (i) provided by the battery 302 and the pulse width (w) of the broadcast signal 306 in order to optimize the total charge provided by the battery 302, the decisive logic of the up-regulation and down-adjustment processes of the automatic calibration is applied, as described below with reference in FIG. 6 and 7.

In FIG. 6 illustrates one feature of the decision logic 600 of an automatic calibration up-adjustment process. According to one of the features, the decision logic 600 can be implemented, for example, by means of a circuit 208. When the decision logic 500 of the automatic calibration process passes to the decision logic 600 of up-regulation of the automatic calibration process, the decision logic 600 determines whether the current has (i ) batteries 302 maximum limit value (i _max ). When the current (i) of the battery 302 has a maximum limit value (i _max ), the execution of the logic circuit 600 continues along the Yes branch to a decision step 604, which determines whether the pulse width (w) of the bit of the broadcast signal 306 is equal to the maximum duration ( w _max ). When the duration (w) of the pulse is less than the maximum duration (w _max ) of the pulse (w <w _max ), in step 610 of the logic circuit 600, the duration (w) of the pulse is increased by a predetermined increment value. According to one of the features, the increment at the frequency f ₁ is about 2 μs, and can be selected from the interval, for example, from about 7.5 μs to about 25 μs. When the pulse width (w) is equal to the maximum pulse width (w _max ) (w = w _max ), no action is taken in step 612 of the logic circuit 600.

When the current (i) of the battery 302 does not have a maximum limit value (i _max ), the logic 600 continues along the No branch to a decision step 606, which determines whether the current (i) of the battery has a minimum limit value (i _min ), which is determined by the value stored in non-volatile memory, for example, about 1 mA. When the current (i) of the battery 302 does not have a minimum limit value (i _min ), the execution of the logic circuit 600 continues along the "No" branch to the step 608 of setting the default pulse duration in order to increase the current limit value. When the current (i) of the battery 302 has a minimum limit value (i _min ), the execution of the logic circuit 600 continues along the Yes branch to a decision step 614, which determines whether the set pulse width (w) is the default pulse width. When the set pulse width (w) is not the default pulse width, the logic 600 continues along the "No" branch until step 616 of increasing the pulse width by a predetermined increment of the pulse width. According to one of the features, the set value of the increment of the pulse duration is about 2 μs. When the set pulse width (w) is the default pulse width, the logic 600 continues along the "Yes" branch until step 618 increases the current limit value (i) by a predetermined increment value. According to one of the features, the predetermined current increment is about 200 μA and can be selected from the interval, for example, from about 200 μA to about 4 mA.

In FIG. 7 illustrates one of the features of the decision logic 700 of the automatic calibration down adjustment process. According to one of the features, the decision logic 700 can be implemented, for example, by means of a circuit 208. When the decision logic 500 of the automatic calibration process passes to the decision logic 700 of the down-adjustment of the automatic calibration process, at decision decision block 702, the decision logic 700 determines whether the current (i) batteries 302 minimum limit value (i _min ). When the current (i) of the battery 302 has a minimum limit value (i _min ), the execution of the logic circuit 700 continues along the Yes branch to the decision step 704, which determines whether the pulse width (w) of the bit of the broadcast signal 306 has a minimum duration ( w _min ). When the duration (w) of the pulse exceeds the minimum duration (w _max ) (w> w _max ), in step 710 of the logic circuit 700, the duration (w) of the pulse decreases (decreases) by a predetermined value of the negative increment. According to one of the features, the magnitude of the negative increment at a frequency f ₁ is about 2 μs and can be selected from the interval, for example, from about 7.5 μs to about 25 μs. When the duration (w) of the pulse is equal to the minimum duration (w _min ) (w = w _min ), at step 712 of the execution of the logic circuit 700, no action is taken.

When the current (i) of the battery 302 does not have a minimum limit value (i _max ), the execution of the logic circuit 700 continues along the "No" branch until a decision step 706, which determines whether the battery current (i) has a maximum limit value (i _max) ) approx. 4 mA. When the current (i) of the battery 302 does not have a maximum limit value (i _max ), the execution of the logic circuit 700 continues along the "No" branch until step 708 setting the default pulse duration in order to reduce the current limit value. When the current (i) of the battery 302 has a maximum limit value (i _max ), the execution of the logic circuit 700 continues along the "Yes" branch to a decision step 714, which determines whether the set pulse width (w) is the default pulse width. When the set pulse width (w) is not the default pulse width, the logic 700 continues along the "No" branch until step 716 of decreasing or decreasing the pulse duration by a predetermined negative increment. According to one of the features, the preset value of the negative increment of the pulse duration is about 2 μs and can be selected from the interval, for example, from about 7.5 μs to about 25 μs. When the set pulse width (w) is the default pulse width, the logic 700 continues along the “Yes” branch until step 718 decreases or decreases the current limit value (i) by a predetermined negative increment value. According to one of the features, the predetermined value of the negative increment is about 200 μA and can be selected from the interval, for example, from about 200 μA to about 4 mA.

As shown in FIG. 8, according to another aspect of the present invention, there is generally provided a device, system, and method for determining the availability of battery power before the communication device received inside the device is in a high current consumption mode. To ensure the operation of an internally received device, such as IEM, whose impedance (Z _BATT ) of battery 802 is determined by the degree of dissolution of the material over time and can vary by ten or more times, it may be desirable to know before broadcasting that battery 802 is capable of providing current consumption. One of the operations of this type is the reading or programming of non-volatile memory, when a failure to read or write to such memory leads to inoperability or malfunctioning of the IEM.

According to one aspect, a battery availability determination circuit 800 may be used to determine the availability of battery power before the communication device received internally in high-current mode of operation. According to one feature, the battery availability determination circuit 800 includes a power-on reset control logic 822 and a low power ADC 812 for determining the impedance (Z _BATT ) of a battery 802. Power-on reset control logic 822 is configured to control the operation of the first and second analog switches 818, 820 for connecting the first, second or third resistance Rl, R2 or R3, respectively, parallel to the battery 802. The voltage 806 that occurs on each resistance R1, R2, R3, given to the input 804 of the frequency memory discretization circuit 808 (S / H). The output 810 of the S / H circuit 808 is supplied to an ADC 812 that measures it. The output 814 of the ADC 812 with the measured voltage (Vb _meas ) of the battery is supplied to the logic circuit 208 (Fig. 3) of the communication system 300 (Fig. 3) to calculate the impedance (Z _BATT ) of the battery 802 based on two or three voltage measurements. Inside or outside the ADC 812, a reference voltage (V _REF ) 816 can be provided.

The following describes the operation of the battery availability determination circuit 800. The power-on reset control logic 822 receives the power-on reset signal 832 and detects when the voltage and the current carrying capacity of the battery 802 have reached a predetermined value. At this point, the ADC 812 is driven, which performs the following measurements. The first analog switch 818 by means of a regulator 826 closes the battery 802 to ground with the first known typical resistance R1, and the ADC 812 measures the battery voltage at the first resistance R1 by means of an S / H circuit 808. Then, the measured voltage (Vb _meas1 ) of the battery is supplied to the logic circuit 208 (Fig. 3). A typical value of the first known predetermined resistance R1 is about 1.5 kOhm and can be selected from the range, for example, from about 1.275 kOhm to about 1.725 kOhm or 1.5 kOhm ± 15%.

The second analog switch 820 by means of the regulator 824 closes the battery 802 to ground with the second known large resistance R2, and the ADC 812 measures the battery voltage at the second resistance R2 using the S / H circuit 808. Then, the measured voltage (Vb _meas2 ) of the battery is supplied to the logic circuit 208 (FIG. 3). A typical value of the second known predetermined resistance R2 is about 15 kΩ and can be selected from the range, for example, from about 12.75 kΩ to about 17.25 kΩ or 15 kΩ ± 15%.

The third analog switch 828 by means of the regulator 830 closes the battery 802 to ground with the third known small resistance R3, and the ADC 812 measures the battery voltage at the second resistance R3 by means of the S / H circuit 808. Then, the measured voltage (Vb _meas2 ) of the battery is supplied to the logic circuit 208 (FIG. 3). A typical value of the third known predetermined resistance R2 is about 1 Ohm and can be selected from the range, for example, from about 0.85 Ohm to about 1.15 Ohm or 1 Ohm ± 15%.

The resistance values R2 of large magnitude and the resistance R3 of small magnitude can be selected so that the resulting voltage at any of the resistances R2, R3 is within the measured ADC 812 of the considered impedances (V _BATT ) of battery 802. By using two of the three measured voltage values (Vb _meas1 ) (1.5 kOhm), (Vb _meas2 ) (15 kOhm) and (Vb _meas3 ) (1 _OHM ) of the battery, the battery impedance is calculated according to the following formula using, for example, (Vb _meas1 ) and (Vb _meas2 ) .

Formula for Vb _meas2 and Vb _meas3 :

The formula for (Vb _meas1 ) and (Vb _meas3 ):

When the impedance (Z _BATT ) of the battery 802 is within acceptable parameters, the 802 battery is allowed to operate in high current mode, however, when the impedance of the battery (Z _BATT ) is outside this interval, the communication circuit 300 (FIG. 3) (e.g., IEM ) returns to standby mode and is activated after a predetermined time or with another input of the power-on reset signal 832.

Embodiment 3

As shown in FIG. 9, according to another aspect of the present invention, there is generally provided an apparatus, system and method based on integrated circuits using a substrate as a negative terminal. In devices based on complementary metal oxide semiconductors (CMOS) using p-type starting material, their substrate is often selected in accordance with the largest negative potential of the system. In the case of an ingested device, such as IEM, the output of this substrate forms a negative terminal of the power source, and the top of the semiconductor wafer is connected to the positive terminal of the power source. With this configuration, it may be difficult to bring the negative terminal to the top side of the plate due to a possible short circuit of the positive terminal during the actuation of the power supply or increase of the leakage current between the two terminals. Due to the difficulty of outputting the negative terminal to the upper side of the plate and using only the output of the substrate, measurement errors may occur when checking the plate due to the impedance between the substrate and the integrated circuits that are connected to the negative terminal. Accordingly, according to one of the features, the output of the negative terminal is proposed, which can be placed on the upper side of the plate with actuation only in test modes and being in a high impedance state in all other operating modes.

Accordingly, in FIG. 9 illustrates one embodiment of circuitry 900 for providing a negative terminal that can be placed on the top side of a plate with actuation only in test modes and being in a high impedance state in all other modes of operation. As shown in FIG. 9, the test logic circuit 902 has an input channel for detecting the test and an output channel 906 connected to the control terminal of the N-channel field-effect transistor device 910. The drain terminal of the N-channel device 910 is connected via a needle probe to the terminal pad V _{SS of the} P-channel semiconductor wafer. The source terminal of the N-channel device is connected to the negative substrate 912 of the semiconductor integrated circuit (IC) and provides an internal connection to the substrate. The IC is first driven with substrate 912 as a negative terminal. By supplying the correct voltage and frequency signature to the test contact 904 of test logic 902, a test mode can be entered. In test mode, a signal is activated that provides in the N-channel device 901 less on-state resistance than the resistance of the substrate 912 in order to redirect electric current through the N-channel device 910 rather than through the output of the substrate 912.

Embodiment 4

The present invention also relates generally to a device, system, and method for separating a power source and a transmission power source in an internally received device such as IEM. In a standard architecture, the IEM power supply is shared by digital circuits, analog circuits, and I / O circuits. With this sharing of the power supply, additional circuits are required to: (1) disconnect the common power supply of the analog and / or digital circuits before transmitting so as not to affect their operation; (2) maintaining sufficient charge in the charge storage device to ensure the operability of analog and digital circuits while the power source is disconnected from them; and (3) connecting the analog and digital circuits to the power source only after the broadcast cycle is completed and only after the voltage of the power source is restored to a voltage equal to or greater than the potential in the power storage device. Accordingly, according to one aspect of the present invention, there is provided a method for physically separating an IEM power supply into a plurality of power supplies of a predetermined magnitude and rejecting a charge storage device. According to another aspect of the present invention, an architecture is proposed to reduce the susceptibility of digital and analog circuits to the interconnection effect that may occur due to the close proximity of power sources to each other.

Accordingly, according to one of the features, a method is proposed that allows you to physically separate the IEM power source into multiple power supplies of a given magnitude and abandon the charge storage device. In addition, an architecture is proposed that is used to reduce the susceptibility of digital and analog circuits to the effect of the relationship, which can occur due to the close proximity of power sources to each other.

According to one aspect, a method is proposed in which a single IEM power supply is divided into many smaller power sources. By adjusting the area of the positive electrode, you can adjust the available charge, which can be supplied to circuits connected to this electrode. In addition, through the use of a small voltage drop controller, the input of which is connected to one of the power sources, and the output is connected to analog or digital circuits controlled by this power source, and which has less potential than the power source, any intermittent effects of the relationship of one power source with another power source.

Two or more power supplies can also be electrically connected and / or disconnected, taking into account the differing energy needs of the analog and digital circuits. For example, if the main function of one power source is to supply energy to broadcast circuits, and the main function of the second power source is to supply energy to all analog and digital circuits during the broadcast cycle, you can use the switch to simultaneously connect both power sources during non-broadcast cycles, providing analog and digital circuits with additional power to perform their functions, which may exceed the power of the second power source, if it is used separately.

Some features of the functional modules described in the invention can be implemented, for example, using a computer-readable medium or device in which a command or a set of instructions can be stored, which, when executed by a computer, may prompt it to carry out a method and / or operation according to the features of the invention. Such a computing machine may comprise, for example, any applicable processing platform, computing platform, computing device, processing device, computing system, processing system, computer, processor, and the like, and may be implemented using any applicable combination of hardware and / or software providing. A computer-readable medium or device may include, for example, memory, a storage device, a storage element, a storage medium, a storage device, a storage element, a storage medium and / or a memory unit of any applicable type, for example, memory, removable or non-removable media, erasable or indelible media, recordable or rewritable media, digital or analogue media, a hard disk, a floppy disk, read-only memory on a compact disc (ROM on a compact disc), a write-once compact disc (CD-R), rewritable compact disc (CD-RW), optical disc, magnetic media, magneto-optical media, removable memory cards or storage disks, a universal serial bus (USB) flash drive, various types of universal digital disks (DVD), tape, tape, etc. .P.

Although various details are provided in the above description, it should be noted that various features of a device, system and method for adaptively optimizing power dissipation and transmission power at a power source of a communication device can be implemented without these specific details. For example, for brevity and clarity, certain features are not presented in detail, in the form of flowcharts. Some elements of the detailed description may be presented in the form of instructions for performing operations with data stored in computer memory. This description and presentation is used by specialists in this field to describe and bring the essence of their work to the attention of other specialists in this field of technology. In general, the term “algorithm” means a self-consistent sequence of steps leading to the achievement of the desired result, with the term “step” denoting the manipulation of physical quantities that can, but need not be, expressed in the form of optical, electrical or magnetic signals that allow storage, transmission , association, comparison and other manipulations. Usually these signals are called bits, quantities, elements, symbols, signs, members, numbers, etc. These and similar terms can be associated with the corresponding physical quantities and are only convenient designations applicable to these quantities.
