Abstract: An electrical connector having an improved seal for sealing a terminal area of the electrical connector. The seal has an engaging surface having a groove extending around the perimeter of the seal, thereby defining a first and second wall. The seal is slidably mounted on a cable, and the cable and seal are inserted in an end of the electrical connector so that a channel is formed by the groove and an inner wall of the electrical connector housing. A sealing material is introduced into the end of the electrical connector until it penetrates the seal between the first wall and the inner wall, thereby causing the channel to become filled with the sealing material. The seal provides a heat sink so that the sealing material solidifies in the channel without penetrating the seal between the second wall and the inner wall, thereby sealing the terminal area of the electrical connector from unwanted moisture.

Abstract: Fuel metering control system in an internal combustion engine utilizing adaptive control having an intake manifold wall's fuel adherence plant. In the system, an actual air/fuel ratio in the individual cylinders is accurately estimated using an exhaust manifold model with an observer. Also, an actual cylinder air flow is estimated using a fluid model. Based on them, a desired cylinder fuel flow is determined by dividing the actual cylinder air flow by a desired air/fuel ratio and an actual cylinder fuel flow is determined by dividing the actual cylinder air flow by the estimated actual air/fuel ratio. The adaptive controller operates such that the actual cylinder fuel flow constantly coincides with the desired cylinder fuel flow. In an embodiment, in order to respond the change in wall adherence parameters, a compensator is connected in series with the wall adherence plant, a virtual plant incorporating the compensator is postulated and when the transfer characteristics of the virtual plant is other than 1 or thereabout, the adaptive controller is operated to have a transfer characteristics inverse thereto.

Abstract: A technique for reducing multiple access interference (MAI) experienced by receivers of transmissions from a transmitter (10), e.g., a base station, in a direct-sequence code division multiple access communication system, e.g. a cellular radio system, is disclosed. The technique provides for the precoding of user signature sequences (a l (t) -- a k (t)) for use in spreading (in 5) information signals (b l (t) -- b k (t)) to be transmitted. The use of precoded signature sequences (c l (t) -- c k (t)) significantly reduces the average level of MAI experienced by the receivers. Despreading of received signals by receivers may be accomplished with the original (i.e., non-precoded) signature sequences (a l (t) -- a k (t)). Thus, no changes to receivers are required. The technique includes a feature for determining a set of sequences for both transmitter and receiver from a smaller set of orthogonal sequences.

Abstract: A communications switch (311) communicates a message to a particular access network endpoint (OE i ) by forwarding an identification of that endpoint along with the message, link- by-link, through the access network, the forwarding being accomplished by using previously stored routing information identifying, at the switch and at each cross-connection point (350, 370), a particular downstream link over which the endpoint can ultimately be reached. The links (345, 365) connecting the cross-connection points are time-division-multiplexed links supporting digital loop carrier and fiber-in-the-loop communications. The routing information is generated and stored automatically by having each network element report information about itself upstream into the network.
