Appl. No.:

09/169492

Inventors:

Xiao Yu Li - San Jose CA
Sunil D. Mehta - San Jose CA
Christopher O. Schmidt - Sunnyvale CA

Assignee:

Lattice Semiconductor Corporation - Hillsboro OR

International Classification:

H07L 29788

US Classification:

257318, 257321

Abstract:

An improved EEPROM cell with a self-aligned tunneling window is provided which is fabricated by a standard STI process so as to produce a smaller layout size and a reduced cell height. The EEPROM cell includes a floating gate, a programmable junction region, and a tunneling oxide layer separating the programmable junction region and the floating gate. The length dimension of the floating gate is less than the length dimension of the tunneling window so that the tunneling window is overlapping the floating gate. The tunneling window is self-aligned by edges forming the length dimension of the floating gate so as to form a self-aligned tunneling window.

International Classification:

H04L 2714

US Classification:

375316, 375350

Abstract:

A decision feedback loop for a receiver for channel estimation and de-rotation of complex input symbols derived from a sampled information signal received via a channel which contains data organized into successive time slots, is configured to retrain and reinitialize the loop during each slot in order to mitigate slot to slot propagation of the estimation error.

US Classification:

707769, 707E17014

Abstract:

Techniques are disclosed for comparing database tables. In one embodiment, the database tables are partitioned. Queries are generated for retrieving each partition. For each generated query, a stored procedure is invoked, using the respective generated query as an input parameter to the stored procedure. The stored procedure is configured to generate a checksum based on the partition retrieved from executing the respective query. The application compares the generated checksums to determine if the partitions and/or tables are consistent.

US Classification:

707771

Abstract:

In particular embodiments, a method includes receiving an unstructured text query, parsing the text query to identify n-grams; determining a score that the n-grams correspond to particular nodes and edges from a social graph, identifying those nodes and edges with a score greater than a threshold score, and then generating structured queries that include references to the identified nodes and edges.

International Classification:

A61H 7/00

US Classification:

601152

Abstract:

A pressure therapy system includes an air pump; a pneumatic line pressurized by the air pump; and a cuff in fluid communication with the pneumatic line, the cuff including flaps sized and shaped to extend around a user's limb, a first chamber and a second chamber separated fluidly by the cuff from the first chamber, wherein the pneumatic line splits into first and second line segments or openings, the first line segment or opening communicating fluidly with the first separated chamber, the second line segment or opening communicating fluidly with the second separated chamber, and wherein the second line segment or opening or a pathway of the cuff leading to the second separated chamber includes a flow restricting structure that delays pressurized air from reaching the second chamber relative to the first chamber.

Inventors:

International Classification:

H04N 701

US Classification:

348446

Abstract:

It is disclosed herein that a system for reducing video data memory in VGA-to-TV converters that convert computer video signals to TV compliant signals for display on regular TV screens. By closely tracking two pointers, one being a write pointer responsible for writing incoming video data into the video data memory and the other being a read pointer responsible for reading out the stored video data in the video data memory, the memory is efficiently used for buffering the video data. To ensure that the read pointer always retrieves the valid video data at its own speed, an address monitoring process is provided to monitor the address difference between the write pointer and the read pointer. When the monitoring process detects that the read pointer may soon surpass the write pointer, a control process is placed on the write pointer to prevent the read pointer from passing over the write pointer. Depending on the speed difference between the write and read pointers, the writer pointer is either paused for a frame time or assigned to a secondary write pointer that writes data into the memory just visited by the read pointer.
