Publication number: 20050032034Abstract: A physical blood sample of animal is sent to a satellite laboratory facility. The blood sample is pre-processed into sub-samples of the sample and the sub-samples are coded. The coded blood sub-samples are physically carried to the main laboratory for analysis. The satellite facility electronically inputs a request for a laboratory analysis by a main laboratory. The request is electronically transmitted to the main laboratory, and the main laboratory coordinates the electronically received input from the satellite facility with the physical blood sub-samples. A computer report of the analysis from the laboratory is obtained for the satellite facility. A clinical pathologist with data of physical characteristics of the animal makes a diagnosis. A menu on a computer permits the generation of a supplemental report to support the diagnosis. An integrated computer report having the laboratory analysis, supplemental report, and a pathologist-enhanced report is electronically communicated to the client.Type: ApplicationFiled: September 1, 2004Publication date: February 10, 2005Inventor: W.

Patent number: 6607910Abstract: A two-chamber perfusion bioreactor counteracts a significant amount of shear stress while allowing high nutrient transfer and removal of waste and/or valuable bio-products, e.g., protein, hormones, growth factors, and monoclonal antibodies without disturbing the cell culture. Cells and tissues, contained in the growth chamber, are suspended in the growth media by rotation of the vessel and are separated by a porous membrane from the feeding chamber. Nutrients and gases are transferred across the membrane from the feeding chamber to the growth chamber. Even dispersion of nutrients along the membrane barrier is accomplished through a novel nutrient dispersion flow path. The flow path is created by flowing media out a center shaft in the vessel and along the front of the nutrient dispersion disk. The fluid then flows around the back of the nutrient dispersion disk and exits the outer center return shaft.Type: GrantFiled: November 13, 2000Date of Patent: August 19, 2003Assignee: Synthecon, Inc.Inventors: S.

Patent number: 6475560Abstract: Using a self-cleaning spray chamber for feed pellets including a dry mass flow meter operatively coupled to a hopper for feed pellet flow and a spray chamber. The spray chamber is configured so that the pellet flow leaving the dry mass flow meter strikes the side wall of the spray chamber that opposes the nozzles located within the spray chamber, thereby causing the pellets to frictionally clean the chamber side wall. This cleaning action substantially reduces the need for manually cleaning the spray chamber as the flow of pellets through the spray chamber removes the liquid additive and assists in the coating of the pellets within the spray chamber. The flow meter provides a wide, relatively thin ribbon of pellets to the wall of the spray chamber that opposes the nozzles. This provides a more even distribution of pellets for coating and better protects the sidewall from overspray coating.Type: GrantFiled: September 27, 2001Date of Patent: November 5, 2002Assignee: AGR International, Inc.Inventor: James W. Dodd

Patent number: 6198271Abstract: A device for locating the edges of wall studs includes a comparison circuit connected to each of three capacitive elements. As the device is moved along a wall, the comparison circuit monitors the relative charge time associated with each capacitive element, the charge times providing an indication of the relative capacitances of the three capacitive elements. Changes in the relative capacitances of the three elements as the device is moved along a wall are due to a change in the dielectric constant of the wall, which normally results from the presence of a wall stud behind the surface over which the device is moved. The comparison circuit uses differences in the measured relative capacitances of the first, second, and third capacitive elements to locate the edges of the stud.Type: GrantFiled: March 26, 1999Date of Patent: March 6, 2001Assignee: Zircon CorporationInventors: Charles E.

Patent number: 6018703Abstract: A software-controlled select and test system for use with a spacecraft. The system reduces the assembly, integration, test time and improves performance of the payload and spacecraft by optimizing the performance using standardized algorithms. The system also reduces the DC power required by the spacecraft, and the thermal dissipation, battery size, solar array size and mass of the spacecraft. This is achieved by optimizing traveling wave tube amplifiers for each channel instead of meeting minimum power requirement over the entire range, wherein most channels have excess power. A serial interface adapter performs the optimization functions via software.Type: GrantFiled: June 18, 1998Date of Patent: January 25, 2000Assignee: Space Systems/Loral, Inc.Inventor: Robert W. Dodd

Patent number: 5956260Abstract: An electronic level includes both a numeric scale and a graphic scale having a "fan-like" configuration of a number of elongated wedge-shaped segments. The inclination of the device is shown numerically using a digital display and, at cardinal angles, graphically by illuminating various segments on either side of a central segment line. The numeric scale provides a numeric indication of the angle of the level from 0.degree. to 360.degree. with respect to a null position, thus satisfying the need to measure absolute angles or slopes. The graphic display provides high resolution at cardinal angles while the numeric display provides lower resolution over 360.degree..Type: GrantFiled: August 9, 1996Date of Patent: September 21, 1999Assignee: Zircon CorporationInventors: Charles E.

Patent number: 5923292Abstract: RF signal nulling and loss of RF lock (i.e., loss of a communications or command link) is resolved by changing the phase of signals derived from first and second (+Z and -Z) antennas so that they add in phase instead of canceling. This is accomplished automatically by using a computer or processor to measure the RF signal level output by a receiver and change the phase of the incoming signal using a phase shifter to achieve the highest level. A squelch circuit in the receiver is used to determine the maximum obtainable RF signal level. The squelch level is compared in a computer to a threshold when the system looks for a higher squelch level. The phase of the phase shifter is changed using a computer to maximize the received signal level. A feedback loop from the receiver through the computer to the phase shifter provides a path to shift the phase of the incoming RF signal in one of the paths so the respective signals add instead of cancel, which eliminates the signal nulling problem.Type: GrantFiled: July 11, 1997Date of Patent: July 13, 1999Assignee: Space Systems/Loral, Inc.Inventor: Robert W.
