Definitions
- the transmit and receiving antennas are preferably resonant antennas, which are substantially resonant, e.g., within 10% of resonance, 15% of resonance, or 20% of resonance.
- the antenna may be of a small size to allow it to fit into a mobile, handheld device where the available space for the antenna may be limited.
- An embodiment describes a high efficiency antenna for the specific characteristics and environment for the power being transmitted and received.
- One embodiment uses an efficient power transfer between two antennas by storing energy in the near field of the transmitting antenna, rather than sending the energy into free space in the form of a travelling electromagnetic wave.
- This embodiment increases the quality factor (Q) of the antennas. This can reduce radiation resistance (R r ) and loss resistance (R l ).
- An aspect describes a magnetically coupled resonance system, that includes a first pad surface against that accepts devices to be provided with power.
- the device uses the magnetically coupled resonance to provide power at a first efficiency of power transfer to devices on the pad surface.
- Power is provided at a second efficiency of power transfer, lower than said first efficiency, to other devices that are not on said first surface, e.g., devices that are remote from the pad by e.g., less than 12 inches or less than 3 feet.
- the devices and pad can each use magnetically resonant circuits with antennas formed of an inductor formed by a coil, and a separate capacitor, tuned to an appropriate frequency.
- the present application discloses use of these techniques to form a wireless desktop.
- the wireless desktop can be used to charge personal electronic devices such as communications terminals, cellular phones, or computer based peripheral devices these charged devices are either or both of powered or recharged, without wires, using a wireless energy transfer technique.
- FIG. 1 shows a wireless desktop with wireless powered items
- FIG. 2 shows an equivalent circuit
- FIGS. 3A-3F show single receivers on pads with and without foldouts
- FIG. 4 shows efficiencies for the single receivers
- FIGS. 5A-5D show pads with multiple receivers
- FIG. 6 shows transfer efficiencies for the multiple receivers
- FIG. 7 shows coplanar field coupling using parasitic
- FIG. 8 shows a desktop parasitic
- An embodiment uses coupled magnetic resonance using magnetic field antennas. Embodiments may operate at any frequency, but two embodiments may operate either at LF (e.g. 135 kHz) or at HF (e.g. 13.56 MHz), but at short distances.
- One embodiment uses a loop coil in series with a capacitor as the antenna.
- the receiver part e.g., the portable device
- the receiver part is intended to be placed directly on the pad.
- there is a relatively small, fixed distance between the transmitter and receiver may be set by the thickness of the material of the pad and the material of the housing. This may be less than a centimeter or less than 10 mm, between the coils forming the transmitter and receiver. The distance will be constant, so the item is always the same distance from the antenna when pressed against the pad.
- the antenna can be tuned to have a maximum response at that constant distance.
- This tuning as well as other tuning operations described in this specification, can be calculated and then optimized by trial and error, for example.
- this system can also charge items which are located at a distance, e.g., inches or feet from the antenna.
- the antenna is less efficient when charging at a distance, but will still provides power at that distance. That allows charging of items that are not directly placed on the charging pad - unlike pure inductive systems which provide in essence no charge at all other than at the very specific fixed distance and/or orientation.
- the lower level charge can be, for example, between 0.05 watts and 0.25 watts, for example, even when the device is not precisely placed on the pad.
- the antenna of the power transmitter/power base may be incorporated into a host device that normally exists on a desktop.
- host device as including either a PC monitor or a lamp, but can be any other item, such as a printer, scanner, fax machine, telephone, router, or the like.
- the transmitter unit may be powered directly from the 110/230 VAC supply already existing in this host device, thus not requiring an extra power cord or power connection.
- This coplanar orientation can be used, for example, for wire loop antennas integrated into keyboards, mouse devices, and into many other electronic devices such as mobile phones, MP3 players, PDAs, etc. if placed in the usual manner. This may, however, be used in other applications.
- Each power base may also provide an area to place devices directly on the wire loop antenna, resulting in strongest coupling, thus enabling high power transfer at high efficiency.
- This close proximity coupling is attained by providing a surface 105 , for example, adjacent the charging coil.
- more than one device may be placed on such a charging pad surface 105 . This has the other advantage of allowing a larger coil for the transmitting, which also provides improved efficiency.
- Low power devices with long battery autonomy such as a keyboard or a computer mouse
- a keyboard or a computer mouse may be placed in the proximity or vicinity of a power base to charge by proximity coupling. Available power and transfer efficiency for these devices will be lower than for the fixed distance coupling.
- these devices may be constantly charged, and intermittently used. Hence, these devices do not require continuous charging.
- the amount of charging may be reduced when other devices are additionally placed on the charging pad, because the multiple devices may more heavily load the system than a single device.
- Magnetic field strength in the vicinity of a power base will preferably be below safety critical levels.
- the power base may additionally provide a function to automatically reduce magnetic field strength if a person is approaching. This function may use infrared or microwave person detection 108 . This can be a proximity detector, e.g., one that can be activated by user proximity.
- a first embodiment actuates the proximity detector manually. Persons that feel uncomfortable in presence of magnetic fields can turn on the function. This function will can also cause devices in the vicinity to stop receiving power during the time when persons are in proximity. This may use, for example, an IR detector to detect the presence of persons.
- a charging station may provide more area and/or space to integrate an efficient power receiver other than the portable device itself. For example, this may use electrical contacts, or by using a wireless technique or a wireless parasitic antenna, as described herein.
- the charging station itself may be configured and used as a power relay or a parasitic antenna that improves coupling between the transmitter and the portable devices which receive the charge.
- FIG. 1 there may be a number of different electrically operated devices on a user's “desktop”, which may be items used by a user for work every day.
- a monitor 100 for a PC This operates off power provided by a 110 V connection 102 which plugs into the AC outlet.
- the 110 V connection 100 provides power for both the operation of the monitor, and also provides the power for the wireless surface 104 that is integrated into the base of the monitor.
- the charging pad may use the techniques that are described in detail herein.
- Wireless proximity charging may be enabled in the area 105 , which forms a flat surface on the base.
- the wireless proximity charging may be specifically tuned for short distance connections, although it may also operate properly over longer distance connections.
- Surface 105 may be sized such that devices such as cell phones and PDAs such as 107 may be rested on the surface. While charging is optimized for the area 105 , charging is still carried out in other areas.
- charging base 112 there is also another charging base as part of a desk lamp 110 .
- the charging is optimized for carrying out up close proximity charging of items such as 114 using magnetically coupled resonance. It may also charge items that are distant from the charging base.
- either or both of the items produces magnetically resonant output power that is coupled to remote devices that are enabled for wireless charging.
- These remote devices may include a magnetically resonant antenna therein that is resonant to the same frequency of the transmission. In an embodiment, this may be at 13.56 MHz or at 135 Khz, or at any other frequency.
- the charged devices can include a digital camera 121 , a wireless mouse 122 , and a wireless keyboard 123 .
- Each of these devices can include a battery therein, which is charged by the operation of the device.
- An important feature is that an up close charge can be carried out at high efficiency, or a distance charge can be carried out lower efficiency.
- FIG. 2 shows an equivalent circuit of the power transmission system, and illustrates how the efficiency can be calculated.
- a power source 200 portion includes a power source 205 , for example the AC socket.
- the power source 205 has an equivalent loss resistance 210 .
- the loss resistance 210 models the resistance and power conversion losses.
- the power source can include some parts of the conversion electronics, for example in the case that the power from the power source is changed to some other frequency or some other power value.
- the power source 205 is connected across terminals 215 , to antenna part 220 .
- Antenna includes an inductor 230 and series capacitance 235 .
- the LC constant of the inductor and capacitance is tuned to be substantially at the frequency of the source 205 .
- the antenna also has shows a loss resistance value 235 , which is a parasitic value that represents the transmit antenna losses, including internal losses, external losses, and radiation losses.
- a magnetic field 250 is created in the vicinity of the antenna 230 . This is coupled to the antenna 240 of the receiver. As in the antenna 230 , the antenna 240 includes an inductor 242 capacitor 244 . The inductor and capacitor form a circuit that is resonant with the received frequency that is received.
- Receive antenna losses are shown by the series resistance 246 .
- the input power P r is connected via the terminals 248 to a load 260 .
- the load 260 also includes receive power losses 262 shown as a series resistance, which can be modeled as losses in the system.
- the transmit antenna can be tuned by changing the capacitance to obtain resonance at the operating frequency in the presence of an unloaded receiver.
- the resistance of the load is infinite. Loaded receivers change this resistance.
- Receiver measurements can also be carried out, by tuning the receiving antenna to change the capacitance etc. in the presence of an unloaded transmitter or in the case of multiple transmitters.
- Capacitance value adjustments can be available, for example, for unloaded, moderately loaded (e.g, a single load) or highly loaded systems. Different capacitance values can be dynamically switched to create the highest efficiency value, and to operate with that value.
- FIGS. 3A-3F show different scenarios of charging.

- the medium pad may be 18 cm in diameter in this embodiment.
- FIG. 4 shows how the different size devices can be located on the different size pads. Five of the six situations have efficiencies which are greater than 80%. Even the lowest efficiency, created by a large pad with an integrated receiver in the phone, had a transfer efficiency of 50%.
- FIGS. 5A-5D may use multiple receivers all on the same pad. Since the pads, especially the large and medium pads, have sizes that are large enough to physically hold multiple different phones, multiple different devices can be placed all on the pad.
