    摘要: A vehicular battery operated charger (202) for charging an electronic device such as a radio (204) includes a controller (218). Controller (218) determines the battery voltage of the vehicles battery (222) and compares it to a threshold level stored in controller (218). Charger (202) will automatically charge radio battery (206) as long as the voltage level of the vehicles battery (222) does not drop below the threshold level stored in controller (218).

    摘要: A battery charging system (10) includes a charging path (50) for charging batteries (14) which have a variety of different charging parameters requiring different optimum charging algorithms (58). The battery charging system (10) comprises a charging algorithm sensing circuit (30). At least one battery cell (14A, 14B) having a positive (23) and a negative terminal (27) and an optimum charging algorithm is to be charged. An impedance (R18) having two terminals and a value related to a predetermined charging algorithm of the cell approximating the optimum charging algorithm is coupled to one of the positive or negative terminals of the battery cell (14B). A capacitor (C72) combines with the impedance (R18) to form a characteristic related to the predetermined charging algorithm. Battery terminals (23 and 27) connected to the cell (14A and 14B) and to one of the terminals of the impedance (R18) form a battery (12) for connecting the cell (14A-B) into the battery charging system (10) with the cell (14A-B) in the charging path (50), and the impedance (R18) and the capacitor (C72) in the charging algorithm sensing circuit.

    摘要: An apparatus and method of determining a communications mode. An operating condition of a device is monitored to determine if the operating condition satisfies a condition for loss of charging of a power pack of the device. Examples of operating conditions that satisfy a condition for loss of charging of a power pack of the device include determining that a power pack temperature of the power pack exceeds a power reduction temperature threshold and determining that a net electrical current drawn from the power pack exceeds a net charging electrical current delivered to the power pack. In response to determining that an operating condition of a device satisfies a condition for loss of charging of a power pack of the device, a wireless communications mode of the device is switched from a first mode to a second mode, where the second mode consumes less energy than the first mode.

    摘要: A lithium-ion battery (126) is normally charged using a constant current/constant voltage charge regime (206, 210), where the battery is charged to a preselected normal voltage level (210) whereupon the voltage is maintained at the limit while the charging current diminishes. The battery charge capacity can be selectively increased by charging the battery to an enhanced voltage level (212) and it can recorded that the battery voltage passed the normal voltage limit. The enhanced charging mode is selected by a user via a device user interface (112), or alternatively by a broadcast command (304) transmitted to the device.

    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.

    摘要: The invention concerns a method (200) and system (100) for flash control. The method can include the steps of—in a portable electronic device (122)—detecting (212) a request to operate a flash component (132), determining (214) whether to delay a timing of the operation of the flash component and if the timing will not be delayed, selectively disabling (224) a transmission component (114) for the portable electronic device. The selective disablement can create an operational opportunity (324) for the flash component. The method can also include the step of operating (224) the flash component during the created operational opportunity. As an example, the portable electronic device can be a mobile communications unit having a camera (136), the flash component can provide a flash for the camera and the transmission component can be a power amplifier (128).
