Patent TW-546975-B (TW)
Title: Efficient handling of connections in a mobile communications network
Inventor: WILLARS PER HANS AKE
IPC: H04W36/18
Filed: 2000-03-31
Granted: 2003-08-11
Abstract: Efficient channel switching procedures are provided in a mobile communications system. A first channel is established to support a connection through a radio access network to a mobile station. Subsequently, if the first channel is no longer used to support that connection, a portion of that first channel is nevertheless maintained for a period of time. That way, if the first channel is again needed to support the connection to the mobile station, the maintained portion of the first channel is simply reactivated thereby reducing channel switching costs and delays associated with channel set-up and release operations. The portion of the first channel that is maintained may be associated with resources within the radio access network. Another portion of the first channel, corresponding for example to a radio channel resource supporting the connection between the radio access network and the mobile station, may be released after the first channel is no longer being used to support the connection in order to make that radio channel resource available for other mobile connections. In one example embodiment, the first channel corresponds to a dedicated type of channel that is reserved for the connection with the mobile station, and the connection is switched to a second type of channel corresponding to a common channel that is not reserved for a particular mobile station, i.e., it is shared by plural mobile stations. In another example embodiment, the first channel is one of plural channels established between the mobile station and the radio access network in accordance with a handover operation. The invention allows the connection to be quickly and efficiently switched back from the common channel to the dedicated channel (the first example embodiment) and to a cell which previously supported the connection (in the second example embodiment).

Title: Driving method of plasma display panel and apparatus thereof
Inventor: HUANG JIH-FON
IPC: G09G3/292
Filed: 2000-09-21
Granted: 2002-07-11
Abstract: The present invention relates to a driving method of plasma display panel (PDP). The total write voltage difference is added between the sustain electrodes and the scan electrodes at the first time point of the reset period when gas discharge only takes place in non-display areas, so-called dark field gaps. Since no discharge takes place in display areas, not only excessive brightness during the reset period that can affect image display quality may be avoided but also adequate wall charges may be accumulated so to lower the required driving voltage in future gas discharges.

Title: Optical techniques for measuring parameters such as temperature across a surface
Inventor: RENKEN WAYNE
IPC: G01K11/12
Filed: 2001-02-13
Granted: 2001-09-21
Abstract: A sensor of a parameter such as temperature includes an indicator encapsulated within a rigid enclosure, wherein the sensor has a characteristic that varies with the parameter that is detectable upon illumination with electromagnetic radiation through a window of the enclosure that is transparent to the radiation. In a specific example, the indicator changes an optical characteristic such as its color as a function of its temperature, and may be of an irreversible type in order to indicate the peak temperature reached. The sensor may include a pattern of such indicators that have different peak temperatures to which they respond, so that the sensor gives a unique visual pattern at each temperature within its measurement range. This pattern may be viewed directly or processed by computer to compare the pattern with those which indicate known temperatures. The sensor and system utilizing it have particular advantages for operation in a vacuum, and/or under ion bombardment, such occurs in plasma etching and deposition machines, and/or within a strong electromagnetic field, such as within the radio frequency and microwave frequency ranges. An array of such sensors positioned across a surface of a thermally conductive substrate is especially useful for measuring a temperature distribution occurring across semiconductor wafers in wafer processing machinery.

Granted: 2003-03-21
Abstract: The present invention relates to a compiling method and system for generating a sequence of program instructions for use in a processing architecture with architecture resources executing instructions from a corresponding instruction set. A retargetable compiler is used to generate a code using at least two instruction sets in the same processing architecture. One instruction set for a compact code and one for a parallel high performance code. The compact instruction set (compact instruction format) covers a subset (RF11, ALU1, L/S1, BU1) of the architecture, whereas the complete instruction set covers the entire architecture (RF1, UC1, UC2, RF2, UC3, UC4, RF3, UC5, UC6, RF4, UC7). By using the at least two instruction sets of different sizes, the compiler is able to reduce the processed average code length, since fewer bits are needed in the compact code to encode operations and registers.

Title: Method of forming an amorphous layer of a semiconductor structure using a high energy beam
Inventor: EISENBEISER KURT W
IPC: H01L21/3105
Filed: 2001-09-27
Granted: 2003-04-01
Abstract: High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline compound semiconductor layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. To further relieve strain in the accommodating buffer layer, at least a portion of the accommodating buffer layer is exposed to a high energy beam anneal process to cause the accommodating buffer layer to become amorphous, providing a true compliant substrate for subsequent layer growth.
