Filed:

Jul 12, 2005

Appl. No.:

11/180016

Inventors:

Khanh Lam - El Monte CA, US

International Classification:

H01R 25/00
H01R 27/02
H01R 31/00
H01R 33/92
H01R 33/94

US Classification:

439654

Abstract:

A compact electrical power outlet system includes a base, multiple electrical receptacles adapted to receive an electrical plug, a power input for receiving electrical power, and an electrical system including a power switch. A movable cover mounted on a top surface of the base is adapted to cover the power switch. The electrical system is adapted to provide the electrical power received via the power input to each of the electrical receptacles when the power switch is in an on position.

US Classification:

330298

Abstract:

A low-noise, low-distortion clamping scheme includes a bootstrapped voltage clamp and an R. sub. gm current clamp that provide superior overdrive protection when used together in a Class-AB feedback amplifier. The bootstrapped voltage clamp includes a transistor that is connected to a circuit node to be clamped. The transistor's base is bootstrapped to the node to maintain a constant V. sub. be when not clamping, to reduce the adverse effects of the junction capacitance C. sub. je which would normally vary with the node voltage and distort the signal at the node. Two such clamps provide positive and negative voltage limiting. The R. sub. gm current clamp is used in the input stage of a Class-AB feedback amplifier to limit the current through the resistor R. sub. gm that interconnects the current inputs of two transconductance amplifiers whenever the voltage drop across R. sub. gm increases to an unacceptable level.

US Classification:

296 971

Abstract:

The glare shield of the present invention includes a transparent shield that is polarized or tinted to reduce glare. This shield is pivotally secured to a rearview mirror by way of a first and second bracket. Each of the brackets includes a hinge piece and the shield includes two hinge pieces. These hinge pieces combine to pivotally secure the glare shield to the brackets. Additionally, magnets are secured to both the brackets and the glare shield. By way of the magnets, the glare shield can be kept in an upright orientation.
