摘要:
A battery charger (230) is provided for charging a battery (210) at high temperatures. The charger (230) includes a thermistor (236) for monitoring the ambient temperature and a rapid charger (232) for providing the charge current to the battery. When the ambient temperature exceeds a high threshold temperature and when the battery (210) needs to be charged at this temperature, the battery charger (230) rapid charges the battery until the battery temperature reaches a cut-off temperature. The cut-off temperature is a temperature having a fixed level above the ambient temperature.

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.

A communication device (100) that includes a transceiver (210), a sensor (230) that detects proximity of the communication device with respect to a user (105), and a controller (205) that selectively changes at least one operating parameter of the transceiver when the sensor detects that the communication device is proximate to the user. The operating parameter that is changed can includes a transmit power of communication signals generated by the transceiver and/or a data transmission rate of signals generated by the transceiver. The communication device also can include a first antenna (215) and a second antenna (220), and the operating parameter that is changed can include a selection of the first antenna or the second antenna through which to transmit an RF signal. The sensor can sense a value of electric field intensity, a value of capacitance, or acoustically measure a distance between the communication device and the user.

A system (130) and method (500) of operating a main display (301) in a radio (300) can monitoring (502) a use characteristic of the radio. Such use characteristics being monitored can include use of an internal speaker or an external speaker, an open angle (303) of the radio, a type of call, a time of day, a user location, a Caller ID, a holster status, a headset status, a cradle status, a network status, a prepaid minute status, a bus status, or a volume level status). The method can further selectively deactivate (504) the main display based on the use characteristic. In one example, the radio can selectively deactivate (508) the display or backlights when the flip portion is opened to answer the incoming call. The main display (or backlight) can also be selectively activated (510) upon a user button selection if a user desires such activation.
摘要:
The invention concerns a method (200) of generating an array (100, 300, 400) having a reduced number of input/outputs (114, 314, 414). The method includes the steps of, for each array row input/output, grouping (212) at least one set of rows (124, 324, 424) in which the set of rows is coupled to the array row input/output and, for each combination of the array row input/outputs, selectively coupling (216) non-set rows (326, 426) to the array row input/outputs that comprise the combination. At least a portion of a number of rows (110, 310, 410) for the array is equal to the number of rows in each set of rows multiplied by the number of array row input/outputs plus the number of non-set rows coupled to the array row input/output combinations.
摘要:
The invention concerns an apparatus (100) for indication of a charging condition. The apparatus includes an indication circuit (126) having at least one electromagnet (120) and a charge control circuit (128) for controlling charging current to a portable device (110). The indication circuit causes the apparatus to electromagnetically engage the portable device and the charge control circuit provides charging current to the portable device during the engagement. The indication circuit also causes the apparatus to electromagnetically decouple the portable device when the portable device is charged to a predetermined level to permit a user to remove the portable device from the apparatus.

The invention concerns a system (100) and method (300, 600) of conveying an image (400, 700, 800) position. The method includes the steps of displaying (312, 612) at least a portion of an image on a display (112) and modifying (314, 614) the portion of the image to convey to a user a position of the portion of the image in relation to the entire image. The image can include a background (412) and at least one symbol (410) superimposed on the background. The modifying step can include graduating (316) the contrast of at least a portion of the background in relation to the symbols. In addition, the step of graduating the contrast includes varying (318) at least one of the hue, brightness and saturation of the background.

A charging system (100) for charging electronic devices. The charging system (100) includes a power distributor (110) and a power receiver (112) in which the power distributor (110) transfers power to the power receiver (112) when the power receiver (112) engages the power distributor (110). The power receiver (112) induces a charging current in an article that is supported by the power receiver (112). The power receiver (112) can include an inductor plate (146) having a first charging coil (148), and the article can be a garment (156) having an embedded electronic device (158). The garment (156) can include a second charging coil (162), and the first charging coil (148) can induce the charging current in the second charging coil (162).
