Filed:

Oct 25, 2005

Appl. No.:

11/258303

Inventors:

Jian Chen - Flushing NY, US
Dennis Q. Chen - Flushing NY, US

International Classification:

B60R 19/44

US Classification:

293142, 293109, 293126

Abstract:

A bumper protection device for automobile bumpers to shield the bumpers from impact attaches to the automobile by a fabric shroud which attaches around the hood and trunk latch and suspends an impact resisting padded guard portion, adapted to the vehicle bumper, covering the entire front or rear bumper, the padded guard portion being drawn partially around the sides of the bumper and anchored by at least one elastic strap attached to opposing ends of the bumper guard portion, each elastic strap being further attached to the tires or wheel wells of the automobile retaining the bumper protection device over the entire rear bumper surface and around the sides of the bumper.

Appl. No.:

16/548675

Inventors:

- Orange CA, US
Jian Feng Chen - Fords NJ, US

International Classification:

H03H 9/215
H03H 9/02
H01L 41/04

Abstract:

The disclosed technology generally relates to quartz crystal devices and more particularly to quartz crystal devices configured to vibrate in torsional mode. In one aspect, a quartz crystal device configured for temperature sensing comprises a fork-shaped quartz crystal comprising a pair of elongate tines laterally extending from a base region in a horizontal lengthwise direction of the fork-shaped quartz crystal. Each of the tines has formed on one or both of opposing sides thereof a vertically protruding line structure laterally elongated in the horizontal lengthwise direction. The quartz crystal device further comprises a first electrode and a second electrode formed on the one or both of the opposing sides of each of the tines and configured such that, when an electrical bias is applied between the first and second electrodes, the fork-shaped quartz crystal vibrates in a torsional mode in which each of the tines twists about a respective axis extending in the horizontal lengthwise direction.

Abstract:

The disclosed technology generally relates to quartz crystal devices and more particularly to quartz crystal devices configured to vibrate in torsional mode. In one aspect, a quartz crystal device configured for temperature sensing comprises a fork-shaped quartz crystal comprising a pair of elongate tines laterally extending from a base region in a horizontal lengthwise direction of the fork-shaped quartz crystal, wherein each of the tines has formed on one or both of opposing sides thereof a pair of vertically recessed groove structures laterally elongated in the horizontal lengthwise direction, wherein the pair of groove structures are separated in a horizontal widthwise direction by a line structure. The quartz crystal device further comprises a first electrode and a second electrode formed on the one or both of the opposing sides of each of the tines and configured such that, when an electrical bias is applied between the first and second electrodes, the fork-shaped quartz crystal vibrates in a torsional mode in which each of the tines twists about a respective axis extending in the horizontal lengthwise direction.
