Current Feedback Differential Amplifier Clamp

View page
US Patent:
58595694, Jan 12, 1999
Filed:
Apr 14, 1997
Appl. No.:
8/843200
Inventors:
Hieu M. Le - Midway City CA
Lloyd F. Linder - Agoura Hills CA
Erick M. Hirata - Torrance CA
Benjamin Felder - Saugus CA
Roger N. Kosaka - Torrance CA
Donald G. McMullin - Rancho Santa Margarita CA
Kelvin T. Tran - Carson CA
Assignee:
Raytheon Company - El Segundo CA
International Classification:
H02H 720
H03M 112
US Classification:
330298
Abstract:
A current steering circuit diverts bias current from a differential current summing amplifier's front end when the differential input exceeds a safe threshold level, thus preventing the amplifier's output stage from being overdriven. Diverting the front end's bias currents also turns off transistors within the amplifier's front end and thus protects the front end from damage which may otherwise result from excessive input signals.

Temperature Compensated Amplifier

View page
US Patent:
58595686, Jan 12, 1999
Filed:
Apr 11, 1997
Appl. No.:
8/827854
Inventors:
Hieu M. Le - Midway City CA
Lloyd F. Linder - Agoura Hills CA
Erick M. Hirata - Torrance CA
Don C. Devendorf - Carlsbad CA
Assignee:
Raytheon Company - El Segundo CA
International Classification:
H03F 130
US Classification:
330289
Abstract:
An amplifier includes an amplifying circuit and bias current circuit. The bias current circuit includes a beta matching circuit which employs a temperature compensated current reference to develop a bias current for the amplifying circuit. The beta matching circuit is connected to track the current gains of transistors within the amplifying circuit and to thereby provide a temperature compensated bias current to the amplifying circuit. The bias current maintains a fixed bias point regardless of temperature-induced, or other, variations of the current gains of the amplifying circuit's transistors.

Hub And Valve Systems For An Aspiration Catheter

View page
US Patent:
20220387057, Dec 8, 2022
Filed:
Jun 28, 2022
Appl. No.:
17/809517
Inventors:
- Las Vegas NV, US
Benjamin William Bobo - Las Vegas NV, US
Brandon Matthew Repko - Mars PA, US
Hieu Le - Fountain Valley CA, US
International Classification:
A61B 17/22
A61B 17/221
Abstract:
A valve system for a catheter, such as an aspiration catheter, is disclosed and includes a valve having a proximal end and a distal end. The distal end of the valve is coupled to the catheter. The valve has a flexible lumen in a first state that is constricted or twisted. The valve system is housed within a hub, where actuation of a button on the hub causes the proximal and distal ends of the valve to rotate relative to each other to put the lumen in a second state that is unconstricted or untwisted state.

Catheters With Expandable And Collapsible Lumens

View page
US Patent:
20220387058, Dec 8, 2022
Filed:
Jun 28, 2022
Appl. No.:
17/809536
Inventors:
- Las Vegas NV, US
Benjamin William Bobo - Las Vegas NV, US
Brandon Matthew Repko - Mars PA, US
Hieu Le - Fountain Valley CA, US
International Classification:
A61B 17/22
A61B 17/221
Abstract:
The present specification is directed towards catheter devices having expandable and collapsible lumens. Air or fluid is pumped into the catheter wall to cause it to expand. Alternatively, wires are embedded within the wall and a direction of flow of electrical current through the wires is modulated to enable the catheter device to be in the collapsed or expanded state. For example, a first wire is embedded within the wall and is helically wound along a length of the catheter device. A second wire is provided that can be removably positioned within the lumen. The direction of flow of electric current through the first and second wires is modulated to enable the catheter device to be in the collapsed or expanded state.
