20090237312, Sep 24, 2009

Filed:

Mar 13, 2009

Appl. No.:

12/381602

Inventors:

Edward A. Schober - Haddon Heights NJ, US
James W. Pollock - Mount Laurel NJ, US

International Classification:

G01R 29/08

US Classification:

343703

Abstract:

The present invention involves a transmitting antenna system that includes at least one high impedance transmitting antenna element, a voltage sampling device, and monitoring equipment. The antenna element(s) each have a driving point that receives radio signals from a radio frequency power source. A voltage sampling device measures the voltage magnitude and phase of the radio signal at the driving point of each antenna elements. A voltage sampling device is physically located near each of the antenna elements being monitored and each voltage sampling device transmits information relating to phase and voltage magnitude to the monitoring equipment that is located remote of at least one of the antenna elements. The monitoring equipment can compare the phase and voltage magnitude of each of the antenna elements in the transmitting antenna system to a pre-determined set of values and/or to the values of the other antenna element(s) in the transmitting antenna system.

Appl. No.:

5/971414

Inventors:

Horst Witzke - Princeton NJ
James W. Pollock - New Egypt NJ

Assignee:

Refac Electronics Corporation - Barkhamsted CT

International Classification:

G09F 900

US Classification:

340785

Abstract:

Driving circuitry is disclosed for electrochromic displays, the driving circuits providing specific characteristics necessary for such displays. Particularly, apparatus is provided to minimize variations in the optical density and in the contrast between the various segments of a device. Further, simultaneous coloring and bleaching signals are provided to the display, thereby avoiding an undesired visual effect of unsynchronized formation for a character on a display device. The circuitry moreover includes components to prevent repeated energization of a segment in a display device. Additionally, circuitry is provided for generating bleach and color signals for the display. Additionally, a power supply for electrochromic displays, requiring bipolar outputs, is disclosed utilizing a single, unipolar, unregulated source therein.

Inventors:

James Eric POLLOCK - Rockville MD, US

International Classification:

A61B 17/135

Abstract:

A blood vessel compression device including a C-shaped spring and a clamp at an end of the spring to compress a blood vessel. The clamp may have a flat shaped cross section or spatulate cross section with an edge where the edge confronts a blood vessel to compress it. The clamp may have a channel and a sac inflatable with air to compress the blood vessel. The device may be positioned on body to clamp an external jugular vein or cephalic vein for cannula insertion. The C-shaped spring may be spaced from a front of the neck to not compress a windpipe of the neck.
