Abstract: A system and method for locating a portable locator device in a communications network. The portable locator unit (PLU) (4) is activated either by an external signal (62) generated in response to remote activation source, such as a subscriber (6, 8) or PLU detector (106, 108), or by an internal activation signal triggered e.g. by the wearer. Once activated, the PLU (4) transmits a location signal (66). This location signal (66) is received by one or more network service nodes (20, 22, 24) which forward the information along with identifying service node information to a network location processor (26, 28). After having determined the location of the PLU (4) from the received information, the network location processor (26, 28) forwards this information to a designated source, such as the requesting subscriber or other authorized user (6, 8).

Abstract: A remote meter reading system (10) includes a remotely accessible meter interface unit (12). The meter interface unit (12) is operable in an activated mode and in an inactivated mode. The meter interface unit (12) is periodically activated to monitor a communication channel to detect whether there is communication activity (410). When communication activity is detected (430), the meter interface unit (12) is operated in a message monitoring mode to monitor the communication channel (450, 460). When a message addressed to the meter interface unit (12) is detected during the monitoring period (470), the meter interface unit (12) is placed in an activated mode for an extended time period to process communication signals (485). If no communication activity is detected when periodically activated (430), or if no message addressed to meter interface is detected during the monitoring period (470), the meter interface unit (12) is placed in an inactivated mode (440).

Abstract: A communication system utilizes multiple spreading codes to transmit high data rate information. The system codes high data rate user information (201) and partitions the coded information (202) into blocks comprised of two bits, B1 and B2. Based on the representation of bits B1 and B2, the system chooses one of a possible four spreading codes (W1 and W2 and their phase reversals W1' and W2') to be utilized for transmission. Once received, the transmitted signal is input into correlators (306, 309) specific to each spreading code W1 and W2, and the maximum absolute value output from the correlators (306, 309) is determined. From this determination, the transmitted spreading code W1, W2, W1' or W2' is determined. The use of multiple spreading codes allows for the transmission of high data rate information without altering the wireless air interface of the communication system.

Abstract: Audio degradation is minimized in scenarios where tandem coding occurs. One such scenario is in the environment of voice mail service. Characteristics of an audio information signal are determined, and the signal is classified (303) as to whether further coding (306) should be performed and, if so, which rate/type of coding should be performed. Characteristics of the audio signal which are determined are, inter alia, quality characteristics, rate of previous coding, type of previous coding and the source of previous coding of the audio information signal. The source of previous coding determined may further include, inter alia, an analog network, a digital network, a PSTN or a wireless communication system. Based on this information, the voice mail service will either choose not to further code the audio information signal or code the audio information signal with the best coding algorithm available.

Abstract: A communication device (100) utilizes pilot symbols to decorrelate a plurality of CDMA signals without using power control. The received signals are filtered in a matched filter bank (103) and sampled in a sampler (104). A vector of the samples is stored in a memory (107) and the inverse cross correlation matrix is calculated by a computing device (105). The matrix is then multiplied by the energy estimates in a multiplier (108). The result is then subtracted from the vector in a summer (109). The result of the subtraction is multiplied by the inverse correlation matrix in another multiplier (110) in order to decode the signals in a decoder (112). Energy estimates of the plurality of CDMA signals are generated in an energy estimator (111) and given polarities based on the known polarity of the pilot symbols. These estimates are used in the subsequent multiplication of submatrices.

Abstract: In a liquid crystal display (400), a crosstalk correction signal which is the same for all video or pixel input signals is provided either directly from the input signals or from the column signal. The input signals are combined with the correction signal and modulated onto carrier signals, then, e.g., may be coupled to the LCDs (445) through a single-wire row of column connection. The correction signals can be derived from either the pixel input signals or the column signal.

Abstract: Mobility is provided for wireless local loop radiotelephone systems by providing the home access network of a subscriber unit (109) with a home access number. Upon registration of the subscriber unit with its home access network (111), the home access number is transmitted to the subscriber unit for storage there. When the subscriber unit moves to a visited access network (113) and registers there, the subscriber unit transmits the home access number to the visited access network, which uses the home access number to contact the home access network. Since all call originations and terminations by and to the subscriber unit occur via the individual subscriber line appearance at the PSTN (105), a minimum of special network elements are required for subscriber unit mobility when the home access number is stored at the subscriber unit.

Abstract: An electronic antenna switching system switches between an internal and an external antenna (105, 107) on a portable radiotelephone (103). Here, the external antenna (107) contains a coil cord connector (111). In the coil cord connector (111) an electrical ground or a predetermined voltage is applied to a center conductor (205) of a coax cable (201). Internal to the radiotelephone (103), an antenna detector circuit (113) detects when the second antenna (107) is attached to the electronic antenna switching system and generates a control signal (119) in response thereto. A switch (115) switches the active transmission path between the internal and the external antenna's transmission path in response to the control signal (119).
