Abstract:
A data compression/decompression processor implements a modified Ziv-Lempel ("LZ") coding technique. The processor includes three modules, an interface, a coder-decoder ("CODEC"), and a MODEL. The CODEC and the MODEL modules together form compression engine, in which the CODEC provides variable length coding and data packing, and the MODEL implements the LZ processing. The MODEL uses content addressable memory ("CAM") in encoding mode for text storage and character matching, and uses CAM in decoding mode as an on-chip RAM to obtain high speed access.
Abstract:
A delay circuit that can be implemented in a monolithic integrated circuit includes a plurality of capacitor/laser-fusible link series pairs. Delay of a binary output signal of the circuit with respect to an input transition is directly proportional to the amount of capacitance connected into the circuit. Because the laser-fusible links can selectively be opened with a laser, the amount of capacitance connected into the circuit can incrementally be reduced; thus, the delay of the circuit is reducibly adjustable to a desired value. By including a plurality of conductive element/laser-fusible link series pairs in the delay circuit, the delay of the circuit is also increasingly adjustable. A method for economically adjusting the delay of each of many like delay circuits embodied in a semiconductor wafer includes measuring a sample of the delays of the delay circuits, calculating an average delay, determining the difference between a desired delay and the average delay to determine an incremental amount of delay to eliminate or to add, determining from predetermined data which fusible links should be opened, and using a laser beam to open the appropriate links.

Abstract:
A clocking system for a self-refreshed dynamic memory (10) for reading data stored in a memory cell (30) and including clocking circuitry (68) includes detecting changes in an address signal (60). The method further includes generating a memory refresh signal (64, 66) in response to detecting changes in the address signal (60). The memory refresh signal (66) is applied to the semiconductor memory circuit (30) for refreshing data stored in the memory cells of the semiconductor memory circuit (30). After the application of the memory refresh signal (66) to the semiconductor memory circuit (30) the address signal (16) is applied to the semiconductor memory circuit (30) for accessing the addressed memory cell to thereby read the data stored therein. The clocking circuitry (68) is reset and precharged during the application of the refresh signal (66) to the semiconductor memory circuit (30).
Abstract:
Analog-to-digital conversion through successive approximation is implemented by means of a charge coupled device. During the conversion process two charges are compared, each comparison yielding one bit of a multi-bit number. By increasing the lesser of the compared charges after each comparison, the need to subtract charge as part of the successive approximation process is eliminated.

Abstract:
In some examples, a system processes event data and video frames produced by a program during execution of the program, the event data representing user actions with respect to a graphical user interface (GUI) of the program. The system identifies an area of the GUI that corresponds to a respective user action of the user actions, wherein identifying the area of the GUI uses a first video frame before an event corresponding to the respective user action, and a second video frame after the event corresponding to the respective user action. The system identifies, based on the identified area, a test object representing a user interface (UI) element, and generates a test script for testing the program, the test script including the test object.
Abstract:
The invention discloses a packing bag of a liquid crystal display (LCD) and a packing method thereof. The packaging bag of a liquid crystal display includes a bag body and an opening. A sealing structure which can be repeatedly unsealed/sealed is disposed at the opening. The invention adopts the sealing structure at the opening of the packing bag to conveniently seal/unseal the opening of the packing bag. Therefore, the packing bag can be circularly reused and decrease the cost. The packing bag is sealed by the sealing structure without folding of the packing bag to decrease material of the packing bag and further decrease the cost.
