    Abstract: PROBLEM TO BE SOLVED: To provide a multiple mode communication equipment that adopts a user interface and has a carried component on a multiple surface of an equipment to minimize the size and cost of equipment in which a user can make privacy communication. SOLUTION: The communication equipment 104 is provided with two housings 108, 110 and each of the housings 108, 110 includes circuit components 114, 115, 116, 117, 118, 122, 123 to operate the communication equipment 104 in different modes. The communication equipment 104 is provided with a latch 112 that connects the two housings 108, 110 removably and turns one of the housings 108/110 to the other 110/108. The communication equipment 104 is switched among different modes based on the connection/disconnection of the housing 108, 110 and on the relative position of them.

    Abstract: A method, information processing system, and portable electronic device for associating metadata with a media file are disclosed. The method includes storing at least one media file (216) associated with identification information. A data set is retrieved from at least one data source. The data set is retrieved at least in part based on the identification information. Metadata (220) is automatically generated without user intervention from the data set based at least in part on the identification information. The metadata (220) is associated with the at least one media file (216).

    Abstract: A ratiometric circuit (40) includes a differential capacitive sensor (42) for sensing a change in capacitance, a differential capacitive detector (46) operatively connected to the differential capacitive sensor for detecting a change in the capacitance of the differential capacitive sensor, an error voltage generator (48) operatively connected to the differential capacitive detector for generating a corrective voltage in response to the detected change in capacitance, and a bias circuit (50) operatively connected to the differential capacitive sensor for generating a bias voltage inversely proportional to and independent of a supply voltage for maintaining the ratiometricity between an output voltage of the differential capacitive sensor and the supply voltage.

    Abstract: A .pi./4-shift differential quadrature phase shift keying (DQPSK) modulator modulates a digitized voice signal and other information. A frequency modulation (FM) modulator modulates the analog voice signal and other information. The FM modulator is coupled to the quadrature mixers (109 and 110) of the .pi./4-shift DQPSK modulator. When an FM modulated signal is required, the mixers (109 and 110) are biased (114) to allow carrier feedthrough by applying a fixed, non-zero DC signal to one or both mixers (109 and 110). The carrier is then FM modulated using conventional methods such as voltage-modulation of a phase locked loop (PLL)(113). When .pi./4-shift DQPSK is to be generated, the conventional baseband I and Q vector-length signals (101 and 102) are applied to the mixers (109 and 110), and the carrier is left unmodulated by switching (115) out the input signal to the PLL (113). The PLL (113) will then generate only the carrier frequency to be mixed with the I and Q vector-length signals (101 and 102).
