Title: Three-terminal inverting hysteretic transistor switch
Inventor: CONGDON JAMES S
IPC: H03K17/30
Filed: 2000-07-25
Abstract: An Inverting hysteretic transistor switch having an input terminal (13), an output terminal (17) and a ground terminal (15) includes, in some embodiments (11), a metal-oxide semiconductor field effect transistor (MOSFET) having an on switching state and an off switching state. The MOSFET includes a drain terminal connected to the output terminal, a gate terminal and a source terminal connected to the ground terminal. The switch further includes a hysteresis circuit (12) connected to the input terminal and to the gate terminal of the MOSFET. In use, with an input voltage having low-to-high and high-to-low input voltage transitions applied to the input terminal, the hysteresis circuit switches the MOSFET to its on switching state at a first threshold voltage during low-to-high input voltage transitions. In addition, the hysteresis circuit switches the MOSFET  to its off switching state at a second threshold voltage, which is less than the first threshold voltage, during high-to-low input voltage transitions.

Title: Multipole acoustic logging with azimuthal spatial transform filtering
Inventor: GEORGE WALLACE R A
IPC: G01V1/44
Filed: 2001-08-28
Abstract: A method and apparatus are provided for detecting a received acoustic pulse of a selected azimuthal borehole mode in a liquid-containing borehole in a formation. The method uses a sonde having an axial array of acoustic receiver stations aligned with the borehole, each receiver station having an azimuthal array of at least four piezoelectric receiver elements, the receiver elements uniformly spaced apart around the azimuthal array. An acoustic pulse transmitted within the borehole produces an electrical signal at each receiver element. Azimuthal spatial transform filtering is applied to produce data representing a received acoustic pulse of the selected azimuthal borehole mode. In one embodiment, azimuthal spatial DFT filtering is applied to digital data produced by analog to digital conversion. In another embodiment, cosine transform filtering is applied by an apodised receiver element.

Title: Reading and decoding information on packages
Inventor: JANKEVICS ANDRIS
IPC: G06V30/10
Filed: 2001-01-18
Abstract: In the system of the present invention, packages (25) are randomly placed on a conveyor belt (27), with their labels facing a two-camera subassembly (12). As the conveyor belt (27) moves, the two-camera subassembly (12) continuously takes images of the belt underneath the overhead camera. The design of the camera permits it to take a high resolution image of a non-singulated, unjustified package flow. A digital image of the packages within the field of view of the camera is then transferred to the processing system for analysis.  The processing system identifies individual packages (25) in the image, extracts them and then analyzes the information written on the package labels.  The analysis process utilizes conventional Optical Character Recognition (OCR) and Intelligent Character Recognition (ICR) techniques to evaluate the information written on the package label. Once the information is decoded, the system either accesses a database record associated with the decoded machine-readable code, or creates a new record. When an unknown word image is encountered, the field-specific recognition process is aided by use of lexicon information, optimized based on installation-specific or user-specific criteria. The lexicon information is continuously revised based on processed form information.

Abstract: A novel wavelength routing apparatus that uses a diffraction grating (201) t o separate a multi-wavelength optical signal from an input port (210)into multiple spectral channels; a channel-interleaving assembly (230) (e.g. an array of prisms) to interleave the spectral channels into two channel groups ; and "augmented relay system" (240) to relay the interleaved channel groups onto two separate arrays (203A, 203B) of channel micromirrors, respectively. The channel micromirrors are individually controllable and pivotable to reflect the spectral channels into multiple output ports (210). The inventiv e wavelength routing apparatus can route the spectral channels on a channel-by - channel basis and couple any spectral channel into any one of the output por ts (210). Further, the channel-interleaving scheme effectively effectively "enlarges" the channel spacing and thereby allows the channel micromirrors i n each array to be made considerably larger and more reliable, thereby significantly improving the channel filtering characteristics and ensuring more robust performance.
