Patent number: 6124710Abstract: According to the present invention, a zero-speed rotary pulse generator is disclosed. The zero-speed rotary pulse generator detects and counts shaft rotation of DC motors. The invention measures the rotation of a shaft by being coupled to a disc-shaped magnet having alternating polarity on its face. The magnet rotates at the same speed as the motor. Positioned close to the rotating magnet is a Hall effect device that can sense the alternating magnet polarity as the shaft rotates. The Hall effect device provides a digital output based upon the direction and the strength of the magnetic field it senses.Type: GrantFiled: November 13, 1998Date of Patent: September 26, 2000Assignee: CTS CorporationInventor: David L.

Patent number: 5999083Abstract: A membrane potentiometer that uses magnets to keep the membranes separated. A controller has a backplate and a cover that has sidewalls and a top wall which has a central opening defining a cavity. The cover mounts to the backplate. A pair of membrane potentiometer are interposed between the cover and the backplate to receive a first voltage, and output a second voltage that is a percentage of the first voltage. A pair of magnet assemblies are located on outer surfaces of the membrane potentiometer to generate a magnetic repulsion force to keep the membrane potentiometer separated from each other.Type: GrantFiled: April 26, 1999Date of Patent: December 7, 1999Assignee: CTS CorporationInventor: David L.

Patent number: 5977782Abstract: A sensor is provided with a conductive sensing element that has a composition adapted to provide a resistance large enough that predetermined magnitudes of voltage noise do not create a false indication of removal, e.g. by abrasion or corrosion. Also, the sensing element composition is adapted to provide a temperature coefficient of resistivity small enough that measurements are substantially independent of temperature. Resistance is preferably greater than 10 ohms and the absolute value of TCR is preferably less than 1000 parts per million per .degree. C. The conductive sensing element may be formed from several materials, including alloys of palladium or lead, particularly palladium-gold, lead-bismuth, or lead-palladium. A combination sensor is provided that includes an abrasion sensing element and a corrosion sensing element on the same substrate.Type: GrantFiled: January 23, 1998Date of Patent: November 2, 1999Assignee: CTS CorporationInventor: David L.

Patent number: 5934933Abstract: A device that allows for simple cost effective connections to flexible multilayered circuits and flexible membrane switches. The invention provides a connecting device that includes a housing that has a base and a closeable lid. At least one contact is attached to the housing. One end of the contact(s) extends beyond the housing and is suitable for making a connection to an electrical circuit. The other end of the contact(s) is positioned inside the housing for connecting to the flexible circuit board or flexible membrane. The lid can be fixed in the closed position whereby the end of the contact(s) inside the housing is compressed with the flexible circuit. The lid can be attached to the base with a hinge, and when the lid is closed it snap locks in place so that the contact(s) are firmly held to the conductive pads of flexible circuit.Type: GrantFiled: June 20, 1997Date of Patent: August 10, 1999Assignee: CTS CorporationInventors: David L. Kordecki, John Zdanys, Jr.
