Abstract:
A seat buckle sensor system is provided that provides an output representative of a lock condition of a seat belt buckle. The system includes a magnet on an end of a seat buckle lock pin and a Hall device. The lock pin, and magnet on the end thereof, move between a locked position and an unlocked position relative to the Hall device. The magnet imparts a first magnetic flux on the Hall device in the locked position causing the Hall device to produce a first output. The magnet imparts a second magnetic flux on the Hall device in the unlocked position causing the Hall device to produce a second output.

Abstract:
A dielectric resonator system (100) having a dielectric element (102) and an attachment assembly (108) both housed within a casing. The attachment assembly (108) is electrically insulating. The attachment assembly (108) couples the dielectric element (102) to the casing. The dielectric element is internally threaded (133). The attachment assembly (108) includes an electrically insulating support structure (110) coupled to the casing by a nut (112) and bolt (114), both of which may also be electrically insulating. The support structure (110) is externally threaded (128) and is nondestructively removably coupled to the threaded dielectric element (102).
Abstract:
A crank-type linear actuator may be used to provide linear actuation, for example, in a vehicle system. In general, the actuator may use a crank assembly to convert a unidirectional rotary drive motion into a reciprocating linear actuation motion. The actuator may also use magnetic elements and magnetic sensors for non-contact position control of the actuator.
Abstract:
A steering shaft lock actuator including at least one motor having an output shaft; a drive train coupled to the output shaft, a locking pawl coupled to the drive train; and a housing for at least partially enclosing the motor, the drive train, the locking pawl and the locking pin. The drive train may be configured to linearly urge the locking pawl and a locking pin between a locked position wherein the locking pawl and the locking pin extend at least partially out of the housing and unlocked position wherein the locking pawl and the locking pin are retracted toward the housing relative to the locked position. The locking pawl may be positioned to prevent rotational movement of the steering shaft when in the locked position. The locking pin may be positioned to lock the actuator to a steering shaft interface when in the locked position.
Abstract:
An electro-mechanical actuator is provided resisting back driving of a gear train in at least one direction. The actuator includes an internal gear train (101). A clutch (111) is coupled to an output of the gear train and transmits a driving force from the gear train to a clutch output. When a back driving force is applied to the clutch output in at least one direction, the clutch assumes a locked configuration. When the clutch is in a locked configuration the clutch resists rotational movement of the output and back driving of the gear train.
