摘要:
A battery charger (102) includes an input terminal (124) for receiving control signals from radio (104). The control signals are received by a charge controller (112) which provides a charge rate to radio battery pack (106) which is a function of the control signal. Radio (104) includes a controller (126) which can sense the state of the radio battery pack (106), as well as changes in the state of radio (104). Controller (126) can then modify the control signal sent to charger (102) and therefor the battery charge rate proved by charger (102) based on certain changes in the state of battery pack (106) or radio (104).
摘要:
The present disclosure provides for repeatedly charging a rechargeable battery during a single charging session to a steady state voltage to attain a higher charge capacity of the rechargeable battery than a charge capacity of the rechargeable battery existing prior to the rechargeable battery being charged to the steady state voltage. The higher charge capacity is attained without exceeding a maximum allowable charge threshold of the rechargeable battery.

An apparatus and a method in a wireless device provide for reestablishing a dropped call, wherein a wireless device determines a wireless device callback priority, wherein the wireless device callback priority is relative to a second communication device callback priority associated with a second communication device, wherein the wireless device and the second communication device are established in a communication session. A dropped call between the wireless device and the second communication device is detected. In response to detecting the dropped call, and the wireless device callback priority being higher than the second communication device callback priority, the wireless device calls back the second communication device. If, during the calling back, a match between a callback identifier and an incoming caller identifier of an incoming call is detected, the calling back is terminated, and the incoming call is answered.

The invention concerns a light detection power system (105). The system can include a solar cell charging circuit (120) having at least one solar cell (116) in which the solar cell charging circuit can provide power to a power source (114), a lighting circuit (122) that receives power from the power source and a controller (118) coupled to the solar cell charging circuit and the lighting circuit. The controller can enable the lighting circuit when a power level that the controller detects from the solar cell charging circuit fails to reach a first predetermined threshold. The solar cell charging circuit can include a switch (130) that is controlled by the controller. The controller can further enable the switch when the power level that the controller detects from the solar cell charging circuit reaches a second predetermined threshold.

The invention concerns an accessory (112) for coupling to a portable electronic device (110). The accessory includes an interface (120) for coupling to the portable electronic device, an identifier (124) in which the identifier generates at least in part a parameter and at least one speaker (128). Only if the accessory contains more than one speaker, the parameter generated at least in part by the identifier causes an audio amplifier (148) that drives one of the speakers to be activated. In addition, the parameter generated at least in part by the identifier can cause the audio amplifier to be deactivated if the accessory contains only one speaker.
摘要:
A device, method and computer readable medium for configuring settings of a device, such as a wireless device (400), based upon detection of nearby surfaces. The device includes a detection signal generator (330, 334, 338) and a detection signal receiver (332, 336). Detection signals include light generated by a display backlight (334) or a keypad (338) that is detected by a camera (336) or other photo-detector. Further detection signals include non-audible frequency sound signals generated by a speaker (330) and that are detected by a microphone (332). The device includes a processor (320) that configures settings in response to the detection of a nearby surface, such as a portion (520, 522) of a holster (500). The settings of the device, such as the wireless device (400), include at least one of a ring setting, a battery setting, a keypad 338 setting, and a display 334 setting.

A mobile communication device (100) includes a volatile memory (110) and a non-volatile memory (112). Instruction code for operating the mobile communication device is permanently stored in the non-volatile memory, and copied to the volatile memory for execution. The mobile communication device enters a hibernate mode which involves shutting down most of the mobile communication device except power to the volatile memory, which allows a nearly instant apparent start up of the mobile communication device at a later time.
摘要:
A device (102) contains a battery (116) which is recharged under control of a charge controller (112). An external power supply (104) provides charging current and voltage (106). A linear regulator (110) regulates the raw voltage provided by the external power supply. The device (102) also contains a heat-generating sub-system (118). To prevent excess heat generation while charging the battery, the battery charging regime is altered from a conventional regime when the heat-generating sub-system is active. Once the battery voltage reaches a charge limit (208), charge current is ceased (210) until the battery voltage falls to a lower limit (212), at which time the charging current is recommenced.

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.
摘要:
A mobile communication device 100 has a digital subsystem (110) and a radio frequency subsystem (108), and is powered by a battery (102) which is charged via a charge control circuit (106) using an external power supply (104) connected to the mobile communication device in a single path configuration. The mobile communication device permits limited operation of the mobile communication device by a user while the battery voltage is sufficient to power the digital subsystem but not yet sufficient to power the radio frequency subsystem. The delay in operation is minimized, however, because once charging commences, the battery voltage rises sufficiently fast that, typically, by the time the digital subsystem is initialized, enabled, and powered up, the battery voltage will be sufficient to enable the radio frequency subsystem.
