Abstract: A reading circuit comprises a current mirror circuit connected, at a first and a second output node, to the drain terminals of an array cell and of a reference cell; a comparator whose inputs are connected to the output nodes of the current mirror circuit; a ramp generator having an enabling input connected to the output of the comparator and an output connected to the control terminal of the reference cell. Biasing the gate terminal of the array cell to a constant voltage, when the currents flowing in the array cell and in the reference cell are equal, the value assumed by the ramp voltage is proportional to the threshold value of the array cell; at that time the comparator is triggered and discontinues the ramp increase, supplying as output the desired threshold value.

Abstract: A method for chemical-mechanical planarization of a substrate on a fixed-abrasive polishing pad in which a planarizing solution is dispensed onto the fixed-abrasive polishing pad. The planarizing solution is preferably an abrasive-free planarizing solution that oxidizes a surface layer on the substrate without passing the surface layer into solution, and the fixed-abrasive pad has a substantially uniform distribution of abrasive particles fixedly bonded to a suspension medium. The surface layer of the substrate is then pressed against the fixed-abrasive pad in the presence of planarizing solution, and at least one of the fixed-abrasive pad or the substrate moves relative to the other to remove material from the surface of the substrate. In operation, the planarizing solution forms a rough, scabrous layer of non-soluble oxides on the surface layer that are readily removed by the abrasive surface of the polishing pad.

Abstract: A semiconductor structure includes a dielectric layer having first and second opposing sides. A conductive layer is adjacent to the first side of the dielectric layer and is coupled to a first terminal, and a conductive barrier layer is adjacent to the second side of the dielectric layer and is coupled to a second terminal. The conductive barrier layer may be formed from tungsten nitride, tungsten silicon nitride, titanium silicon nitride or other barrier materials.

Abstract: A system and method for the detection of fraudulent use of a wireless telephone system includes a fingerprint analyzer that identifies an unauthenticated wireless telephone as authorized or fraudulent based on a fingerprint of the unauthenticated wireless telephone. The system maintains a valid destination list specific for each authorized wireless telephone. Each valid destination list contains destinations considered to be valid for that particular authorized wireless telephone. When an unauthenticated wireless telephone transmits a call request containing a destination, the system classifies the call as valid when the destination is in the valid destination list for the authorized wireless telephone regardless of whether the fingerprint analyzer identifies the unauthenticated wireless telephone as fraudulent. The system may bypass or terminate the fingerprint analysis, or simply ignore the result of the fingerprint analysis by the fingerprint analyzer.

Abstract: A method and apparatus employs a weighted order stored in a weight table for automatically discriminating optical symbols which may be encoded in any one of at least two symbologies. The weighted order may be dynamically updated to reflect the distribution of symbologies as the symbols are acquired and decoded.

Abstract: A method and system for facilitating communications between technical support specialists in a call center environment. Under control of a first computer, the system displays on a display device a form for tracking time of a technical support specialist. The system then receives a request to communicate with a second technical support specialist and sends to an internet protocol address of the second computer request to communicate with the first technical support specialist. At the second computer system, the system displays on a second display device a form for tracking time of the second technical support specialist. In response to receiving a request sent by the first computer system, the second system displays on the second display device a window informing the second technical support specialist that the first technical support specialist has requested to communicate.

Abstract: An electronic memory device organized into sections which are in turn divided into blocks formed of cells and their associated decoding and addressing circuits, the cells being connected in a predetermined circuit configuration and each block being included between two opposite contact regions which are interconnected by parallel continuous conduction lines referred to as the bit lines. In the present invention, at least one interruption is provided in each bit line near a contact region by inserting a controlled switch which functions as a block selector. Advantageously, the proposed solution allows each block to be isolated individually by enabling or disabling as appropriate the switches of the cascade connected blocks.

Abstract: The present invention provides a bird catching apparatus for deploying a catching net rapidly and surely, thereby catching birds surely. Each end of one side edge of the catching net is respectively connected to a pair of deploying arms of each deploying device via a pole member. Each deploying arm is pulled by a pair of extension springs of a deploying unit, and are locked by a locking unit. At the same time, the deploying arms are pulled upward by an auxiliary arm of an auxiliary urging unit. When the deploying arms locked by the locking unit are released, the deploying arms are surely rotated upward, thereby rotating along a vertical surface for over 180.degree.. The catching net is thus deployed.

Abstract: A computer system is described in which a table created in memory includes drive description data for one or more IDE devices included in the system. A command intercept circuit is described which intercepts device-identification commands and reroutes the device-identification operation to memory. The command intercept circuit includes an address decode circuit which asserts a first control signal upon decoding an address corresponding with the one or more IDE devices. A command decode circuit responds to the asserted first control signal to decode data and asserts a second control signal when the decoded data corresponds with a device-identification command. An address generator responds to the asserted second control signal to generate a memory address where the drive description data table is stored.

An output stage of the LED driver includes a first bipolar transistor coupled between a first supply terminal and the first terminals of the LED's. A first MOS transistor drives the base of the first bipolar transistor. The gate of the first MOS transistor is coupled to a first reference voltage. A second bipolar cascode transistor is connected in series with the first MOS transistor and biased by a second reference voltage such that the voltage across the first MOS transistor does not exceed a limit value.

Abstract: Methods and computer systems for semantically analyzing natural language sentences. The natural language processing subsystems for morphological and syntactic analysis transform an input sentence into a syntax parse tree. Semantic analysis applies three sets of semantic rules to create a skeletal logical form graph from a syntax parse tree. Semantic analysis then applies two additional sets of semantic rules to provide semantically meaningful labels for the links of the logical form graph, to create additional logical form graph nodes for missing elements, and to unify redundant elements. The final logical form graph represents the complete semantic analysis of an input sentence.

Abstract: A PCB support for supporting PCBs during surface mounting processing and other PCB assembly processes. In one embodiment, a PCB stand has a support structure attachable to an elevator table of a PCB processing machine and a platform connected to the support structure. The support structure may be a superstructure that can project away from the elevator table, and the platform may be a beam or other member that can support a significant portion of the surface area on the backside of the PCB. The superstructure and platform operate together to position the height of the platform with respect to the elevator table at an elevation at which the platform supports and interior region of the PCB assembly when the elevator table is in a processing position.
