Patent number: 8389229Abstract: Compositions, methods and devices for the detection of anti-lipoidal antibodies and the diagnosis of disease, for example, syphilis, are described. In particular, a method for immobilizing a lipoidal antigen, comprising cardiolipin, lecithin, and cholesterol, on a solid support (such as a nitrocellulose membrane) is described. The ability to immobilize a lipoidal antigen on a membrane satisfies a long-felt need for membrane-based assay for the detection of anti-lipoidal antibodies. Also described are immunoassay devices for concurrently performing treponemal and non-treponemal tests for syphilis.Type: GrantFiled: March 15, 2012Date of Patent: March 5, 2013Assignee: The United States of America as Represented by the Secretary of the Department of Health and Human Services, Centers for Disease Control and PreventionInventors: Arnold R. Castro, Robert W. George

Patent number: 4815008Abstract: This invention features a mobile robot having a body which has an azimuthal angle that is optimally fixed in space and provides the basic reference for the robot to the outside world. The robot further includes a drive system having wheels for enabling movement of the robot, a synchronous steering mechanism which turns the wheels independently of the body, and a head which turns with the wheels. The robot further includes memory for storing the azimuthal angle of the body, a detector assembly disposed in the head for sensing a navigation beacon and resolving an angular deviation between the head and the beacon, and an element for incrementing the stored azimuthal angle by that angular deviation. A system for enabling orientation adjustment is also disclosed.Type: GrantFiled: May 16, 1986Date of Patent: March 21, 1989Assignee: Denning Mobile Robotics, Inc.Inventors: Mark B. Kadonoff, James F.

Patent number: 4772875Abstract: An intrusion detector has a first sensor for monitoring a first condition and a second sensor for monitoring a second condition in a space to be protected against intrusion; a change in the condition sensed by the first sensor in a target area causes the second sensor to be aligned with the same target area; and if both sensors indicate a change in the respective conditions that they monitor an intrusion is indicated.Type: GrantFiled: May 16, 1986Date of Patent: September 20, 1988Assignee: Denning Mobile Robotics, Inc.Inventors: James F. Maddox, Mark B. Kadonoff, Robert W. George, II, Roger A. Wendt

Patent number: 4701893Abstract: An ultrasonic ranging system includes transformer means with a transformer which is selectively energized to produce a transducer drive signal. An ultrasonic transducer transmits an ultrasonic pulse in response to the drive signal and develops an echo signal upon receipt of an echo pulse derived from the ultrasonic pulse; a shunt switch is connected across a winding of the transformer and is selectively closed to quickly damp the ringing following the transmission of an ultrasonic pulse to a level substantially below the level of the echo signal to permit close ranging.Type: GrantFiled: May 16, 1986Date of Patent: October 20, 1987Assignee: Denning Mobile Robotics, Inc.Inventors: Lon J. Muller, Austin Franklin, Robert W. George, II
