Patent number: 9664705Abstract: In an embodiment, a speed sensor includes a first portion, a second portion, and a third portion. The first portion includes a sensing assembly for generating a signal associated with a movement of an object external to the speed sensor. The second portion includes a wiring harness for transferring the generated signal to a device external to the speed sensor. The first portion and the second portion are joined. The third portion is over-molded over a point of the speed sensor where the first portion joins the second portion. Over-molding the third portion at the point may act to seal the point from outside contaminants. Moreover, over-molding the third portion at the point may act to strengthen the speed sensor at the point.Type: GrantFiled: January 28, 2015Date of Patent: May 30, 2017Assignee: SENSATA TECHNOLOGIES, INC.Inventors: Carleton M.

Patent number: 5736701Abstract: An electric switch system (10) for use with a motor vehicle transmission has a movable contact assembly (22) mounted on the detent lever (12) linked to the manual valve assembly and a stationary contact assembly (18) mounted in an open housing (16) disposed over one face surface of the detent lever and in facing relation therewith. The housing has a plurality of L-shaped attachment projections (24a, 24b, 24c) each with a leg (24d, 24e, 24f) which, when the switch system is assembled, extends over the opposite face surface (12c) of the detent lever. A locking projection (24g) of the housing is received in a cut-out (12g) of the detent lever when the attachment projections are out of alignment with the detent lever and has a leg (24h) which extends over the opposite face surface (12c) of the detent lever when the housing (16) is rotated relative to the detent lever so that the attachment projections are in alignment with the detent lever.Type: GrantFiled: May 16, 1996Date of Patent: April 7, 1998Assignee: Texas Instruments IncorporatedInventors: Edward F.

Patent number: 5525768Abstract: A switch system (10) is shown having housing members (12, 13) forming a cavity (14) in which an actuator arm (32) is pivotably mounted. Spring electrical contact members (36, 38) are mounted on the actuator arm and slide into and out of engagement with electrical contact segments (26a, 24a) respectively mounted on respective circuit boards (26, 24) as the actuator arm pivots. The actuator arm is formed with a hub portion (32a) received in bores (12b, 13b) of the housing. The hub in turn has a bore (32b) which is received on and keyed to the manual shaft of a vehicle transmission by opposing flat surfaces (32c). First and second annular spring seal elements (34) are received between respective sealing surfaces (12a, 32a) and (13a, 32a) to prevent ingress of debris into cavity (14). Housing member (12) is formed with a connector portion (16) having a generally cylindrical connector shroud (16a) which receives terminal pins (28) which are electrically connected to contact segments (26a, 24a).Type: GrantFiled: February 17, 1995Date of Patent: June 11, 1996Assignee: Texas Instruments IncorporatedInventors: Carleton M.

Patent number: 5440087Abstract: An electric switch used with motor vehicle transmissions is shown in which the switch arm (22') is mounted on a manual shaft (30) to be movable therewith and is received in a housing (44) which has an end freely rotatable about the manual shaft and an opposite end coupled to the detent lever roller (16). Ingress of debris into the housing is prevented, in one embodiment, by annular sealing elements (54, 56) formed of resilient material and having a curved surface extending in a radial direction disposed around the manual shaft (30) on either side of the switch arm between the switch arm and the housing. In a second embodiment a single annular sealing element (56) is used on one side of the switch arm (22") and the switch arm (22") on its opposite side and the base (12") of the housing are formed with matching curved surfaces (27, 29).Type: GrantFiled: January 3, 1994Date of Patent: August 8, 1995Assignee: Texas Instruments IncorporatedInventor: Carleton M.

Patent number: 4837545Abstract: A circuit breaker device has a chamber in which is disposed a single break contact system using low contact resistance material mounted on movable and stationary supports arranged in a loop configuration in order to direct arcs between the contacts through an arc chute into a remote portion of the chamber. A push-button is connected through a kinematic linkage which transfers motion using minimal frictional engagement to a movable contact to bring the movable contact into and out of engagement with a stationary contact and to latch the contacts in engagement during normal operation. A cantilevered current carrying bimetal transfers motion caused by I R heating of the bimetal to an ambient compensating bimetal connected to the latch mechanism. The kinematic linkage includes a latch surface which engages a rollable cylindrical reaction surface of the latch mechanism to cause the movable contact to come into engagement with the stationary contact upon depression of the push-button.Type: GrantFiled: February 26, 1988Date of Patent: June 6, 1989Assignee: Texas Instruments IncorporatedInventors: Carleton M.

Patent number: 4400677Abstract: A circuit breaker has a thermally responsive bimetallic member of substantial resistance properties disposed in the breaker circuit so that it self-heats and moves to trip a mechanism to open the breaker circuit after a selected period of time when a selected overload current occurs in the circuit. Conductors are joined by a thermally separable bond and are disposed in the breaker circuit in selected heat transfer relation to the high resistance bimetallic member to be thermally separated after a selected delay period by heat transferred to the bond from the bimetallic means, thereby to open the circuit in the event that movement of the thermally responsive member is ineffective to open the circuit. Spring means preferably bias the conductors to separate to assure circuit opening when thermal separation of the noted bond occurs. Preferably one of the conductors has a part of reduced cross-section adapted to rupture and open the circuit under alternate circuit conditions.Type: GrantFiled: December 9, 1981Date of Patent: August 23, 1983Assignee: Texas Instruments IncorporatedInventors: Carleton M.
