The invention concerns a system (100) and method (300) for charging a battery. The method includes the steps of supplying (312) a charging current to a battery (110), sensing (314) the charging current to the battery and selectively signaling (316) an electronic device (118) from the battery to indicate at least one parameter of the battery as the battery is receiving the charging current. As an example, the charging current can be from a wireless charger (116). In addition, the parameter can be, for example, a charging state of the battery or a predetermined current threshold of the charging current.

A charging system (108) supplies a source voltage (Vco, FIG. 5) and a source current (Ico, FIG. 5) to a plurality of battery cells (110). The charging system operates according to a method (200) including the steps of determining (202) a capacity for each of the plurality of battery cells (120 and 130), determining (204) a desired cutoff current (Ico1, FIG. 5) for a select one of the plurality of battery cells (120) having the smallest capacity, determining (206) an optimal source cutoff current according to the capacity of the select one of the plurality of battery cells, adjusting (208) the source current according to the optimal source cutoff current, and periodically applying (209) the source current after reaching the optimal source cutoff current.

A device (100) comprises a charging system (102) supplying a source voltage and a source current to one or more battery cells (104). The device operates according to a method 200-300 including the steps of tracking (202) when a user removes a charger from the charging system, determining (204-212) a charging profile from the tracking step, and applying (300-312) the charging profile to the charging system to maximize charging of the one or more battery cells.
摘要:
A system (200) includes a visiting wireless device (202) and a host wireless device (206) that communicate with each other. A shared user interface is commonly used by the two devices. During an ongoing interaction between a user of the visiting device (202) and a user of the host device (206), images of each user (106 and 108) are communicated to the other device and both devices display the images of both user. Through updated images communicated back and forth between the devices, the users “virtually” interact with the shared user interface. A permission level restricts the interactions available to the visiting device (202).
摘要:
A battery pack (104) has an inductive charging interface (112) for charging a battery cell (114) upon coupling to an inductive power supply (210). The battery pack is coupled to a mobile communication device via a radio interface (110), through with a voltage level is applied to a charge monitoring circuit (106). When the mobile communication device is powered off, the voltage level wakes up the charge monitoring circuit so that the charging status of the battery cell can be displayed on the mobile communication device.
摘要:
A system includes a wireless device (101) and at least one stimulator pad (400, 500). The stimulator pad (400, 500) has a set of electrodes (404) that are in communication with the wireless device (101). The stimulator pad (400, 500) is worn on the skin of a user. The wireless device (101) is operable to receive an incoming signal and to place an electric potential on the conductors (404) so that various areas of the user's body are stimulated and the user will receive notification of the incoming signal in a completely silent manner. The pad (400) can be either wired or wireless and can be used to deliver therapeutic body stimulation as well. In another embodiment, the wireless device (101) controls at least one stimulator pad (400, 500) independent of any incoming signal received.

A system for verification of a battery (100) includes the battery (100) and a device (400,500). The battery (100) includes a memory device (135) for storing an identification number and a verification number. The verification number is generated by applying a key to the identification number. The device (400,500) is coupled to the battery (100) and includes a device memory (515) for storing the key and a microprocessor (435,510) for verifying the identification number of the battery (100) by applying the key to the verification number.
摘要:
The invention concerns a method (200) and a system (100) for charging a battery (112). The method includes the steps of determining (214) a charge termination point for the battery, in which the charge termination point produces a charge on the battery that is less than an initial maximum charging capacity of the battery, and charging (224) the battery using the charge termination point for at least a portion of the charge cycles of the battery. The method reduces at least in part the variation of battery capacity over the cycle life of the battery.
摘要:
A system (200) includes a battery charger (278) and a battery (202). The battery (202) includes a thermistor (230), a voltage identifying element (240), a switch (244), a memory device (232), and a battery data contact (228), connected to a data port of the memory device (232) and the voltage identifying element (240). The voltage identifying element (240) determines a voltage that controls the switch (244). When the switch (244) is enabled, the thermistor (230), connected to a battery clock contact (224), is active and a microprocessor (102) on the battery charger (278) reads the value of the thermistor (230) via an analog-to-digital converter. When the switch (244) is disabled, the thermistor (230) is switched out and the battery clock contact (224) is used to clock the memory device (232). The battery charger (278) has a data contact (226) for receiving the battery data contact (228) and a clock contact (222) for receiving the battery clock contact (224). The battery charger (278) further includes at least two switches (204, 206), and the microprocessor (102) is programmed to selectively operate the switches (204, 206).
