Abstract: A circuit includes an analog-to-digital (A/D) converter for multiplexing between a number of analog input signals and converting the selected analog input signals to a digital code representation. The A/D converter includes a comparator having a first input terminal coupled to receive a first reference signal having a number of levels, a second input terminal coupled to receive a multiple number of analog input signals, and a third input terminal for receiving a multiple number of input select signals. The comparator includes a multiplexor coupling the multiple number of analog input signals to a multiple number of corresponding differential pairs. The multiplexor selects one of the multiple number of differential pairs based on the multiple number of input select signals. In one embodiment, the A/D converter is applied in a digital image sensor for performing pixel-level analog-to-digital conversion using a multi-channel bit serial ADC technique.

Abstract: An implantable cardiac stimulator system or medical apparatus comprising an electrical device, a hermetically sealed case, a non-conducting plate in the case, and a plurality of electrical contacts on the plate. The system also has a lead having a plurality of electrodes, and a plurality of electrical conductors coupled to electrical contacts. The lead has a connector with a non-conducting sheet and electrical contacts protruding from the sheet, each of said contacts being connected to an electrical conductor. The contacts on the connector are arranged to contact one of said electrical contacts on the plate. Electrical contacts on sheet may comprise pins extending through the sheet, the pins comprising a bottom section and a flat section. The flat section extends above the sheet and is split by a slot, forming a first tab and a second tab, the second tab being longer than said first tab. One of the conductors of the lead is inserted into a slot of a pin.

Abstract: The present invention is directed to a pet food apparatus for protecting pet food containers from crawling insects. The food containers are located on an upper tray, elevated above a moat tray, which contains water or some other liquid or attractant. The liquid attracts the crawling insects that have come to the vicinity of the pet food apparatus and the insects get trapped in the liquid or other attractant. One or more vertical support structures support the upper tray above the moat tray. The support structures are configured to enable a user to set the height of the elevated tray relative to the moat tray or the ground. The elevated tray can also be configured with cutout or recessed sections to fit matching pet food bowls. A built-in water dispenser can automatically maintain the fluid level in the moat tray.

Abstract: A method of formulating and packaging decision-making elements into a long constraint length Viterbi decoder which involves formulating the decision-making processors as individual Viterbi butterfly processors that are interconnected in a deBruijn graph configuration. A fully distributed architecture, which achieves high decoding speeds, is made feasible by novel wiring and partitioning of the state diagram. This partitioning defines universal modules, which can be used to build any size decoder, such that a large number of wires is contained inside each module, and a small number of wires is needed to connect modules. The total system is modular and hierarchical, and it implements a large proportion of the required wiring internally within modules and may include some external wiring to fully complete the deBruijn graph.
