US Patent:

45845697, Apr 22, 1986

Filed:

Sep 17, 1984

Appl. No.:

6/650835

Inventors:

Michael J. Lopez - Anaheim CA
Howard A. Williams - Santa Ana CA
Henry J. Salvatori - Whittier CA

International Classification:

G08B 2100

US Classification:

340566

Abstract:

The preferred arrangement utilizes a magnet suspended at the center of an elastic cord over a pickup coil. Movement of the magnet is sensed by the coil in that signals are generated by such movement. The signals are processed in the combination of a time delay circuit and a comparator to provide an output which is a measure of acceleration of the element on which the elastic cord is mounted and, in one form, by a measure of jerk in a similar time delay circuit and comparator combination.

International Classification:

A61B 90/00
H01L 23/60
A61B 90/98
A61B 5/06

Abstract:

Markers, microwave probes, and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes an energy converter e.g., one or more photodiodes, for transforming energy pulses striking the marker into electrical energy, a switch, e.g., FET, coupled to the photodiodes such that light from a probe cause the switch to open and close. A pair of antenna wires are coupled to the switch to provide an antenna, the switch configured to open and close when light strikes the photodiodes to modulate signals from the probe reflected by the antenna back to the probe to identify the location of the marker. The marker also includes an electro static discharge (ESD) protection device coupled to the switch to provide protection against an electrostatic discharge event.
