Matrix Switcher With Three-Dimensional Orientation Of Printed Circuit Boards
Matrix Switcher With Three-Dimensional Orientation Of Printed Circuit Boards
US Patent:
2003004, Mar 6, 2003
Filed:
Aug 28, 2001
Appl. No.:
09/939978
Inventors:
Jack Gershfeld - Fullerton CA, US
International Classification:
H04Q001/00
US Classification:
340/002280
Abstract:
A matrix switcher with three-dimensional orientation of printed circuit boards is disclosed. The matrix switcher of the present invention has a number of input printed circuit boards each comprising a matrix input and a number of output printed circuit 5 boards each comprising a matrix output. Plains of the input printed circuit boards are substantially parallel to each other. Plains of the output printed circuit boards are also substantially parallel to each other and at the same time substantially perpendicular to the plains of the input printed circuit boards. Switches are located on either the input printed circuit boards or the output printed circuit boards. A signal can be sent from any matrix input to any matrix output by way of placing the corresponding switches in an “on” position. The three-dimensional orientation of the input and output printed circuit boards of the present invention eliminates stubs, makes layout of connecting wires on the printed circuit boards easy, does not require large layout area and reduces the problem of crosstalk.

Fast Peak Detector Circuit
Fast Peak Detector Circuit
US Patent:
2007003, Feb 8, 2007
Filed:
Aug 4, 2005
Appl. No.:
11/196196
Inventors:
Jack Gershfeld - Fullerton CA, US
International Classification:
H03K 5/153
US Classification:
327058000
Abstract:
A peak detector circuit for video signals is disclosed. The peak detector circuit comprises a buffer operational amplifier, a strap diode and feedback resistor in order to bootstrap an operational amplifier used in the circuit and to isolate and provide feedback for the circuit An alternative embodiment of this invention utilizes a transistor instead of a strap diode to provide faster charging for a hold capacitor used in the circuit through current gain action of the transistor. The peak detector circuit of this invention permits tracing the input voltage while the operational amplifier remains in the active region, where it is the fastest, without going into saturation during negative cycles of the signal.
