Title: Gate valve having low-friction coating over substrate and method for making same
Filed: 2012-04-03
Abstract: A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat fabricated from a ceramic and/or hardfacing alloy matrix composite substrate is mounted to the body at the intersection of the flow passage and the cavity. A gate fabricated from a ceramic and/or hardfacing alloy matrix composite substrate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The engaging faces of the gate and seats are coated with a low-friction material to facilitate sliding. The ceramic and/or hardfacing alloy matrix composite substrate construction of the gate and seats with low friction engaging surfaces enhances the gate valve's bearing stress capacity.

Patent GB-201215471-D0 (GB)
Title: System with high power chip and a low power chip having low interconnect parasitics
Filed: 2012-08-30
Abstract: An IC system includes low-power chips, e.g., memory chips, located proximate one or more higher power chips, e.g., logic chips, without suffering the effects of overheating. The IC system may include a high-power chip disposed on a packaging substrate and a low-power chip embedded in the packaging substrate to form a stack. Because portions of the packaging substrate thermally insulate the low-power chip from the high-power chip, the low-power chip can be embedded in the IC system in close proximity to the high-power chip without being over heated by the high-power chip. Such close proximity between the low-power chip and the high-power chip advantageously shortens the path length of interconnects therebetween, which improves device performance and reduces interconnect parasitics in the IC system.

Title: Method, system and computer program for comparing images
Filed: 2013-03-28
Abstract: A method of comparing two images (100, 200) such as facial images. The method comprises assessing an image quality of each of a plurality of sections of a first image (100), so as to assign an image quality to each of the plurality of sections of the first image. For at least one section (510) of the first image (100) that is determined to have an image quality different (e.g higher) from the image quality of the others sections, an image processing process is performed. The image processing process comprises: configuring a matching algorithm for that section of the first image in dependence on the assigned image quality of the section; and using the configured matching algorithm to compare the section of the first image with a corresponding section of the second of the two images (200) to generate an output. Independent claims are also provided for: 1) a method of verifying a user wherein if a match is found the second image is stored as a validated image; 2) a method of verifying whether a user has been previously authenticated, wherein differences are detected between two recently-acquired images, and if the differences are large enough the user is considered to be live.

Title: Linear electromagnetic machine
Inventor: BENSON GLENDON
IPC: H02K35/02
Filed: 1984-06-11
Granted: 1989-07-06
Abstract: A linear electromagnetic machine has a stator with a coil mounted thereon. A reciprocating element has permanent magnet segments of alternating polarity so that reciprocation of said element relative to said stator in an axial direction causes periodic flux reversal through the coil to induce an alternating voltage therein. The magnetized segments are of equal axial extent and are axially spaced by transitional regions that are of axial extent substantially less than that of the magnetized  segments. Flux return and core elements associated with the stator provides a relatively low reluctance magnetic path for flux lines resulting from magnetization of the permanent magnets wherein the reluctance is generally independent of the position of the reciprocating element.
