Patent number: 6516527Abstract: A digital inclinometer detects an inclination angle by sensing varying conductive current of various electrodes. When the inclinometer is rotated through an inclination angle, various segments of the sensing electrodes become immersed in a conductive fluid causing varying conductive currents to these sensing electrodes. A driving signal is applied to driving of electrode and the sensing side of electrodes is kept at a constant voltage by connecting them to an analog ground or to current sensing amplifier which maintains virtual ground during measurement to achieve an equipotential at both sides of the sensor plates. An Analog to Digital converter, microprocessor, and LCD display achieves a digital readout. Novel methods allow 360-degree precise measurements, while overcoming traditional limitations and errors due to fringe effects, non-linearity, and various environmental changes.Type: GrantFiled: November 3, 2000Date of Patent: February 11, 2003Inventor: Hiro Moriyasu

Patent number: 6517376Abstract: A positioning-sounding device for a card puller, it generates a sound when an inserting and extracting member (an extended card) in the card puller is inserted in position to make sure that the member has been in position. Wherein, a sounding device is mounted in a slide groove of an insertion seat and has a slide block and an elastic element both can slide in the slide groove; thereby, when the inserting and extracting member is moved inwardly of a channel of the insertion seat, it drives the slide block inwardly to compress the elastic element. When the inserting and extracting member is in position, the slide block is abutted against and is released from the inserting and extracting member and is elastically restored to its original position by the elastic element to collide with the inner wall of the slide groove indicating that the inserting and extracting member is surely inserted in position.Type: GrantFiled: October 30, 2001Date of Patent: February 11, 2003Inventor: Chin-Hwa Hwang

Patent number: 6513252Abstract: A compass compensation system is provided for automatically continuously calibrating an electronic compass for a vehicle, without requiring an initial manual calibration or preset of the vehicle magnetic signature. The system initially adjusts a two axis sensor of the compass in response to a sampling of at least one initial data point. The system further calibrates the compass by sampling data points that are substantially opposite to one another on a plot of a magnetic field and averaging an ordinate of the data points to determine a respective zero value for the Earth magnetic field. The system also identifies a change in magnetic signature and adjusts the sensor assembly.Type: GrantFiled: March 31, 2000Date of Patent: February 4, 2003Assignee: Donnelly CorporationInventors: Kenneth L.

Patent number: 6481114Abstract: A finger ring shim is comprised of a member for being wedged between a loose ring and a finger. A groove on the member is arranged for cradling the ring. The groove has a width which is selected to receive a ring of a particular thickness. The member has a shim thickness which is selected to match a gap size between the ring and the finger. A tool for determining the proper groove width and shim thickness is comprised of an elongated and tapered sheet with a scale along an edge, and slots of graduated widths. The sheet is inserted between a finger and a ring until it is snug. The point on the scale under the ring is correlated with a suitable shim thickness, and the smallest slot which the ring can fit into shows the suitable groove width.Type: GrantFiled: July 30, 2001Date of Patent: November 19, 2002Inventor: Nazaret Kalajian
