    摘要: A battery pack (110) having a plurality of cells (103, 105) utilizes a pull up resistor (116) multiplexed between separate voltage supply sources (120, 122) and a single battery contact (106) to monitor individual cell temperatures. A plurality of thermistors (102, 104) are coupled in series between ground potential (108) and the single battery pack contact (106), each thermistor being coupled to one cell of the pack. Individual voltage divider circuits are formed for each thermistor (102, 104) as the pull up resistor (116) is multiplexed between the voltage supply sources (120, 122).

    摘要: A communication device (102) has a loudspeaker (212) that includes a loudspeaker coil. The loudspeaker is used for playing audio signals and for detecting metal in the vicinity of the loudspeaker. To detect metal the communication device includes a pulse generation circuit (216) for generating pulses that are applied to the loudspeaker, and a pulse measurement circuit (222) for measuring response pulses. If the response pulses indicate metal is in proximity to the loudspeaker, an alert is generated to inform the user of the communication device.

    摘要: A wireless communication device (50) can include a radio frequency transceiver (52), an audio drive circuit (58) coupled to the transceiver, a speaker (10) having a voice coil (16) coupled to the audio drive circuit, and an antenna feed or radiating circuit (20) such as an RFID or NFID circuit coupled to the voice coil for at least radiating or receiving an electromagnetic signal via the voice coil. Such radiating circuits can be coupled to the voice coil using a band pass circuit designed to substantially prevent a radiating signal from the radiating circuit from interfering with audio drive circuit driving the speaker. The wireless communication device can further include an antenna (54) coupled to the radio frequency transceiver. Note, this arrangement can be designed to avoid problems involving electrostatic discharge sensitivity, electromagnetic interference coupling between the antenna and the voice coil, total radiated power, and specific absorption rate.

    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.
