Title: Guidance system for guiding an AGV and method for switching an automatic rail-guided vehicle
Inventor: ALOFS CORNELL W
IPC: G05D1/02
Filed: 1999-02-24
Granted: 2002-02-01
Abstract: A guidance system for guiding an automated guided vehicle along a pathway is disclosed which includes rails for holding the AGV to the generally straight portions of the pathway and a non-rail guidance system for directing the AGV from the end of a first rail segment to the beginning of another. The rails provide the necessary level of control to allow an unmanned vehicle to move at high speeds while the non-rail guidance system eliminates the need for the rail switches that would otherwise be needed to shift a rail guided vehicle from one rail portion to another.

Title: Circuit and method for implicitly transposing a matrix of values during the processing of an image
Inventor: LEE WOOBIN
IPC: H04N7/30
Filed: 1999-08-13
Granted: 2001-12-21
Abstract: In one aspect of the invention, an image decoder includes a memory and a processor coupled to the memory. The processor is operable to store a column of intermediate values in the memory as a row of intermediate values, combine the intermediate values within the stored row to generate a column of resulting values, and store the resulting values in the memory as a row of resulting values. Therefore, such an image decoder can be used to store the intermediate Masaki values De and Do of equation 12 in a row of memory such that when the processor combines these values it implicitly generates the transposed resulting intermediate values of the block of figure 9. Thus, such an image decoder eliminates the extra step of reordering the intermediate Masaki matrix of figure 7 to obtain the block of figure 8 and then transposing the block of figure 8 to obtain the block of figure 9. That is, such an image decoder obtains the block of figure 9 directly when executing the equation 13. In a related aspect of the invention, the intermediate values include a first even-position even intermediate value, an odd-position even intermediate value, a second even-position even intermediate value, a first even-position odd intermediate value, an odd-position odd intermediate value, and a second even-position odd intermediate value. The processor stores the first even-position even intermediate value and the first even-position odd intermediate value in a first pair of adjacent storage locations, and stores the second even-position even intermediate value and the second even-position odd intermediate value in a second pair of second pair of adjacent storage locations, the second pair of storage locations being adjacent to the first pair of storage locations. Thus, such an image decoder can generate the transposed and even-odd separated block of figure 10 directly from the equation 13, thus saving even more processing time by eliminating the reordering and transposing steps illustrated in figures 7-9.

Title: Trench semiconductor device having gate oxide layer with multiple thicknesses and processes for fabricating the same
Inventor: WILLIAMS RICHARD K
IPC: H01L21/76
Filed: 2000-08-15
Granted: 2001-10-01
Abstract: The a trench semiconductor device such as a power MOSFET the high electric field at the corner of the trench is diminished by increasing the thickness of the gate oxide layer at the bottom of the trench. Several processes for manufacturing such devices are described. In one group of processes a directional deposition of silicon oxide is performed after the trench has been etched, yielding a thick oxide layer at the bottom of the trench. Any oxide which deposits on the walls of the trench is removed before a thin gate oxide layer is grown on the walls. The trench is then filled with polysilicon in or more stages. In a variation of the process a small amount of photoresist is deposited on the oxide at the bottom of the trench before the walls of the trench are etched. Alternatively, polysilicon can be deposited in the trench and etched back until only a portion remains at the bottom of the trench. The polysilicon is then oxidized and the trench is refilled with polysilicon. The processes can be combined, with a directional deposition of oxide being followed by a filling and oxidation of polysilicon. A process of forming a ""keyhole"" shaped gate electrode includes depositing polysilicon at the bottom of the trench, oxidizing the top surface of the polysilicon, etching the oxidized polysilicon, and filling the trench with polysilicon.

Title: High performance inductors on irradiated silicon wafer
Inventor: HOU CHIEN-TI
IPC: H01L27/04
Filed: 2000-09-01
Granted: 2002-08-11
Abstract: A method for integrating, high performance inductors in monolithic RF-IC's adds an irradiation step to the conventional fabrication process. Using a normal substrate, neutron irradiation is applied to the inductor portions, and the non-inductor portions are masked. Then we fabricate the inductor on the irradiated portions by normal CMOS process. This causes the irradiated substrate portions to become highly resistive, with a decreased concentration of carriers. As a result, both the inherent eddy current losses and the parasitic capacitance between inductor and substrate are significantly reduced, thus enabling a considerable improvement in the quality factor of the inductor.
