Detailed description

The present application considers various embodiments of sensors that have been developed to obtain biometric data. The sensor configurations are suitable for use with frequency orthogonal signaling techniques (see e.g. US 9,019,224 and US 9,529,476 such as US 9,811,214 all of which are hereby incorporated by reference into the present application). The sensor configurations discussed herein can be used with other signaling techniques, including sampling or time division and / or code division. It should be noted that the sensors described and illustrated here are also suitable for use in conjunction with signal infusion (also known as signal injection) techniques and devices.

The currently disclosed systems and methods include principles related to and suitable for the design, manufacture, and use of capacitive-based sensors, and particularly capacitive-based sensors that use a multiplexing scheme based on orthogonal signal transmission, such as, but not only, frequency division multiplexing (FDM), code division multiplexing (CDM) or a hybrid modulation technique that combines both FDM and CDM methods. References to frequencies herein could also refer to other orthogonal signal bases. Thus, the present application contains the content of the previous one by reference U.S. Application 9,019,224 the applicant with the title "Low-Latency Touch Sensitive Device" and the content of the U.S. application 9,158,411 with the title "Fast Multi-Touch Processing". These applications disclose FDM, CDM, or FDM / CDM hybrid touch sensors that can be used in conjunction with the currently published sensors. In such sensors, interactions are detected when a signal from a row is coupled (increased) or decoupled (decreased) to a column and the result is received on this column. By sequentially exciting the rows and measuring the coupling of the excitation signal to the columns, a heat map can be created that reflects changes in capacitance and thus proximity.

The present application also uses principles used in high-speed multi-touch sensors and other interfaces disclosed in the following applications: US 9,933,880 ; US 9,019,224 ; US 9,811,214 ; US 9,804,721 ; US 9,710,113 ; and US 9,158,411 . Knowledge of the disclosures, concepts and nomenclature of these patent applications is assumed. The entire disclosure of these patent applications and the applications incorporated therein by reference is incorporated herein by reference. The present application also uses principles used in high-speed multitouch sensors and other interfaces disclosed in the following patent documents: US 15 / 162,240 ; US 15 / 690,234 ; US 15 / 195,675 ; US 15 / 200,642 ; US 15 / 821,677 ; US 15 / 904,953 ; US 15 / 905,465 ; US 15 / 943,221 ; US 62 / 540,458 , US 62 / 575,005 , US 62 / 621,117 , US 62 / 619,656 and PCT publication PCT / US2017 / 050547 , assuming knowledge of the disclosures, concepts and nomenclature of these patent documents. The entire disclosure of these applications and the applications incorporated therein by reference are incorporated by reference here.

As used herein and in particular within the claims, order terms such as first and second are not intended to imply sequence, time or uniqueness per se, but rather serve to distinguish one claimed construct from another. For some uses where the context dictates, these terms can imply that "the first" and "the second" are unique. For example, if an event occurs at a first time and another event occurs at a second time, the first time is not intended to occur before the second time, after the second time, or simultaneously with the second time. However, if the further limitation that the second time occurs after the first time is defined in the claim, the context would require that the first time and the second time be "read" as unique times. Similarly, order terms should be interpreted broadly, if the context dictates or permits this, so that the two identified claim constructs can have the same characteristic or a different characteristic. For example, a first and a second frequency, without further limitation, being the same frequency, e.g. the first frequency 10 MHz and the second frequency 10 MHz; or it could be different frequencies, e.g. the first frequency is 10 MHz and the second frequency is 11 MHz. The context can dictate something else, e.g. if a first and a second frequency are further limited to be frequency orthogonal to each other; in this case they could not be the same frequency.

Certain principles of a fast multitouch (FMT) sensor have been disclosed in the patent applications discussed above. Orthogonal signals are transmitted into a plurality of transmit conductors (or antennas), and the information is received by receivers connected to a plurality of receive conductors (or antennas); the signal is then analyzed by a signal processor to identify touch events. The transmit and receive conductors can be organized in a variety of configurations, including e.g. a matrix in which the crossing points form nodes, interactions at these nodes being recognized by processing the received signals. In an embodiment in which the orthogonal signals are orthogonal in terms of frequency, the distance between the orthogonal frequencies Δf is at least the reciprocal of the measuring period τ, the measuring period τ being equal to the period during which the columns are scanned. Thus, in one embodiment, a column can be measured for one millisecond (τ), the frequency separation (Δf) being 1 kHz (i.e. Δf = 1 / τ).

In one embodiment, the signal processor of an integrated circuit with mixed signals (or a downstream component or software) is designed such that it determines at least one value that represents each frequency orthogonal signal transmitted to a series. In one embodiment, the signal processor of the mixed signal integrated circuit (or a downstream component or software) performs a Fourier transform on received signals. In one embodiment, the integrated mixed signal circuit is designed such that it digitizes received signals. In one embodiment, the integrated mixed signal circuit (or a downstream component or software) is designed in such a way that it digitizes received signals and carries out a discrete Fourier transformation (DFT) on the digitized information. In one embodiment, the integrated mixed signal circuit (or a downstream component or software) is designed such that it digitizes received signals and carries out a fast Fourier transform (FFT) on the digitized information, an FFT being a type of discrete Fourier transform.

It will be apparent to those skilled in the art in view of this disclosure that a DFT, in essence, treats the sequence of digital samples (eg windows) taken during a sampling period (eg integration period) as if it were repeated. As a result, signals that are not center frequencies (ie, not integer multiples of the reciprocal of the integration period (the reciprocal defines the minimum frequency spacing)), relatively nominal but unintended consequences, by introducing small values into other DFT bins. Therefore, it will be obvious to a person skilled in the art in view of this disclosure that the term orthogonal as used here is not "violated" by such small contributions. In other words, as the term "frequency orthogonal" is used here, two signals are considered frequency orthogonal if essentially the entire contribution of one signal to the DFT bins is made to different DFT bins than essentially the entire contribution of the other signal.

In one embodiment, received signals are sampled at at least 1 MHz. In one embodiment, the received signals are sampled at at least 2 MHz. In one embodiment, the received signals are sampled at 4 MHz. In one embodiment, received signals are sampled at 4096 MHz. In one embodiment, the received signals are sampled at more than 4 MHz.

In order to achieve a kHz sampling, for example 4096 samples can be taken at 4.096 MHz. In such an embodiment, the integration period is 1 Milliseconds, which results in a minimum frequency spacing of 1 KHz under the condition that the frequency spacing is greater than or equal to the reciprocal of the integration period. (In view of this disclosure, it will be obvious to a person skilled in the art that taking 4096 samples at 4 MHz, for example, would result in an integration period of slightly more than a millisecond without a kHz sample and a minimum frequency spacing of 976.5625 Hz being achieved) . In one embodiment, the frequency spacing is equal to the reciprocal of the integration period. In such an embodiment, the maximum frequency of a frequency orthogonal signal range should be less than 2 MHz. In such an embodiment, the practical maximum frequency of a frequency orthogonal signal range should be less than about 40% of the sampling rate or about 1.6 MHz. In one embodiment, a DFT (which could be an FFT) is used to transform the digitized received signals into information bins, each of which reflects the frequency of a transmitted orthogonal signal that may be from the transmitting antenna 130 was transferred. In one embodiment, 2048 bins correspond to frequencies from 1 KHz to about 2 MHz. In view of this disclosure, it will be apparent to those skilled in the art that these examples are illustrative only. Depending on the requirements of a system and taking into account the restrictions described above, the sampling rate can be increased or decreased, the integration period adjusted, the frequency range adjusted, etc.

In one embodiment, a DFT output (which may be an FFT) includes a bin for each frequency orthogonal signal that is transmitted. In one embodiment, each DFT bin (which can be an FFT) consists of an in-phase (I) and a quadrature component (Q). In one embodiment, the sum of the squares of the I and Q components is used as a measure that corresponds to the signal strength for that bin. In one embodiment, the square root of the sum of the squares of the I and Q components is used as a measure that corresponds to the signal strength for that bin. In light of this disclosure, it will be apparent to those skilled in the art that a measure corresponding to the signal strength for a bin could be used as a measure of biometric activity. In other words, the measure that corresponds to the signal strength in a particular bin would change as a result of a particular activity.

In general, as the term is used herein, injection or infusion refers to the process of transmitting signals to a subject's body, effectively making the body (or parts of the body) an active source of transmission of the signal. In one embodiment, an electrical signal is injected into the hand (or other part of the body), which signal can be detected by a sensor even when the hand (or fingers or other part of the body) is not in direct contact with the contact surface of the sensor. In this way, the proximity and orientation of the hand (or finger or other body part) relative to a surface can be determined to a certain extent. In one embodiment, signals are carried by the body (e.g., routed) and, depending on the frequencies involved, can be transmitted near or below the surface. In one embodiment, frequencies of at least the KHz range can be used in frequency injection. In one embodiment, frequencies in the MHz range can be used for frequency injection. To use the infusion in conjunction with the FMT as described above, in one embodiment an infusion signal can be chosen to be orthogonal to the drive signals so that it can be seen on the sensor lines in addition to the other signals.

The sensor devices discussed here use transmit and receive antennas (also referred to here as conductors). However, it should be understood that it depends on the context and embodiment whether the transmit antennas or receive antennas are used as transmitters, receivers or both work. In one embodiment, the transmitters and receivers for any combination of patterns are operatively connected to a single integrated circuit capable of sending and receiving the required signals. In one embodiment, the transmitters and receivers are each operatively connected to a different integrated circuit that is capable of sending and receiving the required signals. In one embodiment, the transmitters and receivers, for any combination of the patterns, can be operatively connected to a group of integrated circuits, each capable of transmitting and receiving the necessary signals, and together sharing information necessary for one Multiple IC configuration are required. In an embodiment where the capacity of the integrated circuit (ie the number of transmit and receive channels) and the requirements of the pattern (ie the number of transmit and receive channels) allow, all transmitters and receivers for all multiple patterns used by a control device operated by a common integrated circuit or by a group of integrated circuits that communicate with each other. In one embodiment, where the number of transmit or receive channels requires the use of multiple integrated circuits, the information from each circuit is combined in a separate system. In one embodiment, the separate system consists of a GPU and software for signal processing.

In one embodiment, there is an integrated mixed signal circuit 105 with signal processing capabilities from one transmitter 110 and a receiver 120 .

However, arranging the antennas so that they provide information related to the biometric data to be acquired and not just quantity can lead to improved measurement capability. In one embodiment, antennas are placed at key positions on or near a body part to obtain biometric data. “Nearby” is usually meant to mean “close enough” that the placement of the antennas is able to provide information about the body part or on the surface of the skin in order to obtain biometric data about a body function.

In one embodiment, transmit and receive antennas (or transmit and receive antenna groups) are placed on the skin, using the dermal changes in the environment to obtain biometric data. In one embodiment, machine learning algorithms are used to associate measured signals with biometric data.

In one embodiment, very small transmitting and receiving antennas are positioned directly at a plurality of locations close to the body and can detect relative movements to one another, this relative movement being able to be used to obtain biometric data. In one embodiment, the antennas are attached to the hair, hair follicles, or skin with small amounts of adhesive.

In use, the amount of signal received by a transmitting antenna is measured at a receiver. With reference to 3rd shows the measured amount of signal received at a particular receiver during a series of integration periods. The activity indicates that more signal is received than during other frames during certain integration periods. The measured signal can be an indication of a biological activity. In one embodiment, the measured signal may indicate biological activity during each individual frame. In one embodiment, the measured signal may indicate biological activity during a plurality of individual frames.

4th Figure 11 is another graph illustrating the measured amount of signal received at a particular receiver during a series of integration periods. In the curve of 4th the delta between the current and the previous received signal is shown. This enables a different perspective of the received signal and can facilitate the visualization of signals that indicate biometric data and their use for creating biometric data.

In one embodiment, the biometric data is associated with certain parts of the body and is used to mark certain parts of the body, e.g. certain veins and arteries, such as the superficial palmar arch, which may be able to give the orientation of a hand relative to a surface. In one embodiment, marking certain arteries with a portable device may allow tracking of the placement of the portable device on the body over a period of time.

As discussed above, to obtain the biometric data, the sensor device 100 localized and / or assigned to the person so that the received signals are measured and measured by the sensor device 100 can be used to provide biometric data. The biometric data can then be used for diagnostic purposes, health-related questions, identification and other activities.

While the invention has been illustrated and described in particular with reference to a preferred embodiment, it will be apparent to those skilled in the art that various changes in form and detail can be made therein without departing from the spirit and scope of the present invention.
