Abstract: A signal constellation is optimized for trellis coded modulation in fast fading channels, where the receiver does not have perfect knowledge of the channel parameters. Specifically, the signal constellation is partitioned into 2n mutually exclusive subsets, each preferably defining two points. Points within each subset are separated from one another by a distance between conditional distributions, preferably a Kullback-Leibler (KL) distance. For a block m=k1+k2 of information bits input into a trellis coder 30, the k1 bits are trellis encoded into n bits (n>k1) and used to select a subset of the constellation. The k2 bit(s) is/are used to select a particular point within the subset. Because the inter-subset distance between points is a KL distance that is effectively greater than a Euclidean distance, error at the receiver is substantially reduced, especially at higher SNR. Using a KL distance ensures statistics of channel fading are inherent within the signal constellation.

Abstract: A personal cart comprises a mounting structure secured onto two parallel and aligned suspension members near their respective proximal longitudinal ends so as to rest thereon, and extending both upwardly and longitudinally so as to generally define an angle with said suspension members, two driving wheels, each mounted to a respective suspension member near its proximal end, two driven wheels, each rotatably mounted to a respective suspension member near its distal end, and actuating means coupled to both driving wheels for selectively causing rotation of at least one of said two driving wheels. The actuating may includes a controller and a rechargeable battery or be in the form of a hand actuating device including two endless belts mounted along angled portions of the mounting structure. The personal cart comprises few components and is relatively compact which provides a long autonomy in the case of an electrically actuated embodiment, and less effort to actuate in the case of the hand actuating embodiment.

Abstract: The invention relates to a method for electrically connecting a conductor to a contact, according to which the electrical conductor that is coated with an insulation is first inserted between two legs of the contact, whereupon a welding device is placed against both legs and the welding process is carried out by turning on the welding current.

Abstract: The invention relates to an automatic fingerprint identification method. In the method according to the invention, identification is executed in three phases. In coarse alignment (32), fingerprints are compared using a few reference points. In fine alignment (33), coincidence of fingerprint minutiae are used to find the best fingerprint matching transformation. In the matching phase (34), individual minutiae of the fingerprint examined are matched against a known template. Parameters are computed from the matching minutiae and used in making the final identification.

Abstract: A data coder includes a combined parallel concatenated convolution coder (PCCC) and a parallel concatenated zigzag (PCZZ) coder, where PCCC functional blocks are re-used in the PCZZ coder for coding at high coding rates. The PCZZ coding rate (R) may be changed by re-partitioning at least one interleaver pattern. A second interleaver for the PCZZ coder is obtained by a transform of an initial interleaving vector. Alternatively, the PCZZ coder re-uses a PCCC interleaver. The PCZZ coder may also use a multi-dimensional concatenation of zigzag codes, and it is shown one may add additional code dimensions (and relevant parity check symbols) by using properties of already specified interleaver(s), and without adding more interleaver(s).

Abstract: A method for operating a wireless communications system includes a step of signalling, between a mobile station to a network, that the mobile station or the network is temporarily ceasing transmission of circuit switched information (DTX), which could be voice frames or data frames. For the case of voice, the method further includes a step, executed in the network, of determining if a current uplink or downlink voice traffic channel that is assigned to the mobile station can be retained by the mobile station, or whether the current uplink or downlink voice traffic channel must be released by the mobile station. Only if it is determined that the current uplink or downlink voice traffic channel must be released by the mobile station, does the network signal to the mobile station to release the channel.
