Abstract: A self-timed data communication system for a wide data width semiconductor memory system having a plurality of data paths is provided. The data communication system includes a central data path including at least one junction circuit configured for exchanging data signals between the central data path and the plurality of data paths of the at least one data path. A respective one junction circuit of the at least one junction circuit includes circuitry for controlling resetting the respective one junction circuit for preparation of a subsequent data transfer through the respective one junction circuit in accordance with receipt of an input junction monitor signal indicating that data has been transferred to the respective one junction circuit. The data communication system further includes a plurality of data banks configured for storing data, wherein a corresponding data bank of the plurality of data banks is connected to a respective one data path of the plurality of data paths.

Abstract: An enclosure for a wildlife surveillance assembly includes a base configured to house a surveillance assembly and a cover coupled to the base with a hinge so as to permit rotating movement therebetween. In addition, the enclosure includes a locking assembly that secures the enclosure to a mounting structure. And prevents removal of the enclosure from the mounting structure without opening the cover of the enclosure. The base further preferably includes first and second compartments that are environmentally isolated from one another and includes openings to accommodate the locking assembly. In the preferred embodiment, the locking mechanism includes a flexible cable having opposed ends, with an abutment coupled to one of the ends. A collar is slidably coupled to the flexible cable and adapted to be locked to the flexible cable at a desired position.

Abstract: An aqueous based ceria slurry system and method for chemical mechanical polishing of semiconductor wafers, the slurry comprising less than 5 wt % abrasive cerium oxide particles and up to about the critical micelle concentration of a cationic surfactant, absent other abrasives, in a neutral to alkaline pH solution is disclosed. Also disclosed is slurry comprising a blend of surfactants including a pre-existing amount of anionic surfactant and an added amount of cationic and/or non-ionic surfactant.

Abstract: A fuel system for an internal combustion engine (10) includes a controller (14) which controls the operation of an engine fuel pump (13). Signals are supplied to the controller by a transducer (16) which is responsive to the passage of teeth formed on the periphery of a wheel (12) which is mounted on the engine crankshaft. In order to generate an engine speed signal it is necessary to know the tooth spacing errors and these are determined by recording two time pulse sequences of signals from the transducer at different engine speeds and loads and then processing those signals to firstly determine the periodic component of the signals due to the fluctuation of engine speed which occurs due to the individual power strokes of the engine.
