Dec 13, 2000

Appl. No.:

09/736709

Inventors:

Raymond K. Chan - Fremont CA
Mario F. Au - Fremont CA

Assignee:

Integrated Device Technology, Inc. - Santa Clara CA

International Classification:

G06F 1204

US Classification:

711201, 711203, 711211, 711212

Abstract:

A first-in-first-out (FIFO) memory device includes a plurality of FIFO memory cores that contain a plurality of cells. A variable cell size circuit supports user programmable cell sizes in a FIFO memory device to permit selection of a wide range of cell sizes. The variable cell size circuit controls successive accesses to a cell in the memory device, and it resets a byte count when the byte; count equals the cell size value to initialize the circuit for a subsequent access operation. The variable cell size circuit further includes a prediction circuit that indicates completion of access to the cell a predetermined number of counts prior to completion of the actual access. An alignment circuit generates data for write operations in cells that store an odd number of bytes per cell to compensate for the two byte per cell read operations. Each FIFO memory core includes a circuit that generates a cell available signal to indicate whether a cell in a corresponding FIFO memory core is available for reading. An arbiter receives the cell available signals, and it generates control signals to select one of the FIFO memory cores.

International Classification:

H04L 12/54

US Classification:

370394, 370412

Abstract:

A system receives data in multiple streams from an upstream device. The system temporarily stores the data in a first buffer and asserts a forward flow control signal when a capacity of the first buffer exceeds a first threshold value. The system reads the data from the first buffer and selectively processes the data based on the forward flow control signal. The system temporarily stores the selectively processed data in a number of second buffers, generates a backward flow control signal when a capacity of one of the second buffers exceeds a second threshold value, and sends the backward flow control signal to the upstream device.

Abstract:

The present invention is directed to immunoassays for detecting one or more target analytes in a fluid sample wherein the detection reaction occurs on a solid support and involves an amplification system. In particular, the invention is directed to making and using a test device having at least one site for detecting the presence of at least one target analyte, wherein a conjugate comprising dextran-polystreptavidin is immobilized at the test site(s) as a capture reagent for a complex containing the target analyze.

Abstract:

A method for identifying a structure in a volume of interest is provided. The method comprises acquiring a plurality of points related to the structure in a continuous mode, and subsequently registering at least one of the points to a previously acquired imaging dataset of the structure. An apparatus, system and a computer-readable medium are also provided. The present invention provides faster acquisition of EAM points by modifying the mapping system so that catheter tip locations are automatically and continuously recorded without requiring explicit navigation to and annotation of fiducial landmarks on the endocardium.

US Classification:

606 11, 600101, 128898

Abstract:

A tissue ablation device employs one or more energy emitters () and one or more photoacoustic sensors () in a cooperative arrangement for applying a tissue ablation therapy to a tissue (). In operation, the energy emitters () emit a tissue ablation beam (TA) into a target portion of the tissue () to form a lesion () therein, and alternatively or concurrently emit a photoexcitation beam (PE) into the target portion of the tissue () to excite a photoacoustic response from the tissue (). The photoacoustic sensor(s) () sense the photoacoustic response of the tissue ().
