IPC: H02M1/12
Filed: 2000-05-06
Granted: 2002-03-21
Abstract: A device and method for providing three-phase pulse-width modulated sine waves includes an inverter including first, second and third legs, and first and second PWM generators, the first PWM generator is coupled to selectively provide an output to the first inverter leg or the third inverter leg, and the second PWM generator is coupled to selectively provide an output to the second inverter leg or the third inverter leg.

IPC: H01L21/66
Filed: 2000-07-07
Granted: 2003-02-11
Abstract: A test probe has a sheet body including an insulating sheet and a wiring sheet formed on the bottom surface of the insulating sheet. The insulating sheet mounts on the top surface a plurality of top electrodes arranged with a small pitch, whereas the wiring sheet mounts on the bottom surface a plurality of bottom electrodes connected to the top electrodes through via-holes in the insulating sheet and interconnect layers in the wiring sheet. A smaller pitch of the top electrodes is suited for a bare chip LSI, whereas a larger pitch of the bottom electrodes reduces the cost for a test board.

IPC: H04N9/31
Filed: 2000-07-19
Granted: 2002-09-01
Abstract: To provide a projector technology to reduce the chrominance nonuniformities in the displayed color image. A projector is provided with an illuminating optical system, a color-separating optical system that separates light into a first through third beam of colored light, first through third electro-optical devices that modulate the first through third beams of colored light to generate a first through third beams of modulated light, a color combiner that combines the first through third beams of modulated light, and a projecting optical system that projects the composite light. In addition, the projector is provided with a λ/2 retardation plate which makes the direction of polarization of the first and third beams of modulated light incident to the color combiner a first direction of polarization, and makes the direction of polarization of the second beam of modulated light a second direction of polarization. The λ/2 retardation plate is provided with one surface open to the atmosphere and its other surface in contact with a transmissive member that does not change the direction of polarization, so it is possible to reduce the chrominance nonuniformities in the color image displayed by the light combined from the first through third modulated light beams.

Title: Dynamic scheduling scheduler framework and method for mobile communication
Inventor: YANG REN-SHUEN
IPC: H04L12/56
Filed: 2000-08-11
Granted: 2002-04-21
Abstract: The present invention provides a method for dynamically partitioning wireless data capacity for packet radio services in time division multiple access (TDMA). The packet radio services are composed of packets with same or different features. In accordance with the present invention, some mobile stations (MS) share one time slot. The interfering information of each MS can be estimated by a request from a mobile station or via the data stream of a base transceiver station. The interfering information and QoS agreement are used as a standard to allocate more time slots to the packet radio services. Therefore, the present invention provides a scheduler framework of dynamic scheduling mobile communication (DSMC) for the data switching network, which includes a channel coding/decoding unit (CCU) and a packet control unit (PCU). The former is used to perform the scheduling operation, and the latter is used to determine the service rate based on the user QoS request and interfering status. In addition, the present invention also provides two kinds of resource allocation strategies (two strategies for allocating resource) for the same cell under the DSMC scheduler framework, which are: one has constant resource allocation based on the speed of the service rate and the volume of the interference; and the other has dynamic resource allocation based on the speed of the service rate and the volume of the interference.

The oxide layer is used as a stop layer to etch the silicon nitride layer on top of the polysilicon gate electrode to expose the oxide layer on top of the polysilicon gate electrode. A patterned photoresist layer is used as a mask to implant the polysilicon gate electrodes of PMOS transistor region and NMOS transistor region. The polysilicon layer and the silicon nitride layer are removed sequentially. Then, a silicon nitride spacer is formed. A patterned photoresist layer is used to implant source/drain of PMOS transistor region and NMOS transistor region. Finally, salicide is formed on the individual polysilicon gate electrodes and source/drain regions.

Granted: 2007-07-21
Abstract: A smart tag device has a nameplate module. With proper adjustment, modification, and judge made by an operation circuit module set inside the smart tag device, the nameplate module is automatically actuated when data stored in the smart tag device match preset conditions, and users are automatically informed that the related information of the current wafer lot match specific preset conditions. Therefore, the user can get aware of the status of the current wafer lot without actively actuating the smart tag device, and this remarkably increases the working efficiency of the user.

Title: System and method for modular multiplication
Inventor: CHEN CHIN-LONG
IPC: G06F7/00
Filed: 2001-12-10
Granted: 2003-05-11
Abstract: The modular exponentiation function used in public key encryption and decryption systems is implemented in a standalone engine having at its core modular multiplication circuits which operate in two phases which share overlapping hardware structures. The partitioning of large arrays in the hardware structure, for multiplication and addition, into smaller structures results in a multiplier design comprising a series of nearly identical processing elements linked together in a chained fashion. As a result of the two-phase operation and the chaining together of partitioned processing elements, the overall structure is operable in a pipelined fashion to improve throughput and speed. The chained processing elements are constructed so as to provide a partitionable chain with separate parts for processing factors of the modulus. In this mode, the system is particularly useful for exploiting characteristics of the Chinese Remainder Theorem to perform rapid exponentiation operations. A checksum mechanism is also provided to insure accurate operation without impacting speed and without significantly increasing complexity. While the present disclosure is directed to a complex system which includes a number of features, the present application is particularly directed to the overall two-phase system with overlapping hardware components.
