US Patent:

6367477, Apr 9, 2002

Filed:

Feb 5, 2001

Appl. No.:

09/776151

Inventors:

Calvin S. Lee - Pasadena CA 91107-3448

International Classification:

A61F 604

US Classification:

128842, 128844, 128918

Abstract:

A contraceptive sheath can provide extra leak protection by forming at least one latex film over the bulbous closed end of a latex sheath liner. A transparent elastic covering overlies the sheath outer surface to seal the latex films against separation from the latex liner.

Appl. No.:

13/660380

Inventors:

Fisker Automotive, Inc. - Anaheim CA, US
Calvin Lee - Novi MI, US
Billy Tally - Dove Canyon CA, US

Assignee:

Fisker Automotive, Inc. - Anaheim CA

International Classification:

F01N 13/04

US Classification:

181228

Abstract:

An exhaust system for a hybrid electric vehicle includes an exhaust pipe. The exhaust pipe includes a first channel having a first end coupled to an engine of the vehicle and a second end that splits into a second and third channel. The second and third channels extend outwardly to a first front side and to a second front side of the vehicle.

Appl. No.:

7/995203

Inventors:

Calvin S. Lee - Laguna Niguel CA
Eliahou Tousson - Van Nuys CA

Assignee:

Lee/Maatuk Engineering, Inc. - Santa Ana CA

International Classification:

G01F 2326

US Classification:

73304C

Abstract:

Digital level sensing probe system including digital probe constructed of two (2) concentric cylinders, forming a set of discrete, cylindrical capacitors that use the substance whose level is to be measured as a dielectric material. The set of capacitors is arranged along the axis of measurement where each capacitor represents a discrete level increment. Each capacitor is assigned a unique time slot in a switching sequence. The first level capacitor is used as a reference to which all other capacitors are sequentially compared. In the switching sequence, an AC signal is applied across each capacitor and compared with the inverted signal which is applied across the first level capacitor. A logic "1" results when the substance is present and a logic "0" when the substance is absent. The logic is decoded and converted to display the appropriate quantity of substance measured.

Inventors:

Calvin S. Lee - Laguna Niguel CA

International Classification:

G01F 2326

US Classification:

73304C

Abstract:

Digital tilt level sensing probe system comprising a set of multiple capacitor elements in a fluid container arranged along an axis of measurement where each multiple capacitor element represents a discrete level increment in dielectric material fluid to be measured. Individual capacitors in each element are horizontally spaced to reflect a level differential upon tilting of the fluid container from its normal attitude. In the case of a probe for sensing tilting in a single plane, a one-piece body is employed to include integral capacitor elements, mounting pad, connector, custom IC pad, and circuitry molded into such body. Alternative references may be employed for comparison with each capacitor assigned a unique time slot in a switching sequence.
