Patent number: 9670449Abstract: A system and method are described for electroporating a sample that utilizes one or more sets of electrodes that are spaced apart in order to hold a surface tension constrained sample between the electrodes. The first electrode is connected to the lower body of the system while the second electrode is connected to the upper body. Both electrodes are connected to a pulse generator. Each electrode has a sample contact surface such that the first electrode and the second electrode may be positioned to hold a surface tension constrained sample between the two sample contact surfaces and the sample may receive a selected electric pulse.Type: GrantFiled: January 5, 2016Date of Patent: June 6, 2017Assignee: APPLIED BIOSYSTEMS LLCInventors: Richard Jarvis, Mike Byrom, Dmitriy Ovcharenko

Publication number: 20160323935Abstract: Systems and methods for controlling the temperature of items such as a sample in a vessel or a specimen, in a thermal bath using thermally efficient pellets as the thermal media. The pellets are typically oblong metallic or oblong metallic-coated pellets with rounded edges, a hardened surface, a smooth polished finish, and characteristics that enable efficient thermal communication between the bath's thermal source, the pellets, and the items that are inserted into the mass of pellets. Further, the pellets are dry and moisture and gas impermeable, and they resist microbial growth and are readily decontaminated by several methods including applying an antimicrobial compound to the pellets. The thermal source is controlled to achieve the desired temperature of the items inserted into the pellets.Type: ApplicationFiled: March 1, 2012Publication date: November 3, 2016Inventor: Richard Jarvis

Patent number: 6612825Abstract: The pillow cutter of a food product extrusion system is provided with motor driven roller means designed to pull filled, or unfilled, extrusions, including hollow tubes, or ropes, of extruded food material from the extrusion die head. The ropes are then cut in various shapes such as square, diamond or triangle pillows, sticks or bars. The roller means constitute rotatable base rollers sized to effect telescopic assembly with removable, interchangeable, tubular, cylindrical cutter sleeves engraved on the outer peripheral surface of the sleeves with variable cutting patterns so the user of the system can optionally change the cutting patterns by selective choice of cutter sleeves.Type: GrantFiled: September 7, 2001Date of Patent: September 2, 2003Assignee: American Extrusion International Corp.Inventor: Richard Jarvis Warner

Patent number: 5619627Abstract: Occulting apparatus for use with an image generator that provides for multiple-level occulting of image data. The occulting apparatus comprises a mask buffer and control logic for processing image data to construct and store an obscurance mask in the mask buffer. Foreground entities contained in the image data are logically ORed into the mask buffer until the entities extend beyond a predefined range from a predetermined image viewpoint. Thereafter, the mask is used by the control logic to reject entities contained in subsequently processed image data that are fully obscured by the foreground entities comprising the obscurance mask. The control logic includes an obscurance manager, a region processor, an object processor, a polygon processor, and insertion logic. The obscurance manager is a controller for building and applying the obscurance mask to the image data.Type: GrantFiled: May 3, 1994Date of Patent: April 8, 1997Assignee: Loral Aerospace Corp.Inventors: Brian T.

Patent number: 5531186Abstract: A cat litter box which has an open topped structural box (20) with a "U" shaped slot (30) on one side (24). A brush seal (32) is disposed within the box interior defining a pair of opposed seals with the bristle ends contiguously positioned in the middle of the slot. A screen grid tray (42) is located inside the box beneath granular litter material 34). In operation, the tray is lifted up by handles (44) on each end sifting the material therethrough capturing cat excrement for disposal. The tray is inserted into the slot parting the brush seal displacing the litter material until it is pushed fully into the box.
