Abstract: Assembly systems and methods are provided for elastically deforming a non-circularly shaped washer while driving the washer through an insertion tool into a workpiece, such as a pressure sensor, having a correspondingly shaped recess with an inner wall diameter less than a maximum radial dimension of the non-circular washer. The washer is released from radial compression into the recess so as to permit the washer to become fixated against the inner wall of the recess by a retention force. The fixated washer has a height greater than a height of the recess inner wall, and may serve as a deformable sealing element between the workpiece and other components.

Abstract: An electronic throttle control assembly for a vehicle has a housing that mounts to a handlebar of the vehicle and defines an interior. A rack gear is mounted in the interior for movement in a linear, translational, and/or radial direction. A pinion gear within the interior moves the rack gear upon rotation of the pinion gear. A sensor target is coupled to the rack gear. A sensor detects a position of the sensor target and generates an electric signal for a vehicle control unit. A grip is coupled to the pinion gear, rotation of the grip moving the rack gear and sensor target in a linear, translational, and/or radial direction, the electric signal varying based on the change in position of the sensor target. Opposing springs within the housing resist movement of the rack gear and rest in a normally preloaded state.

Abstract: A sensor assembly comprising a sensing element with at least one electrical lead extending therefrom. A tube encloses the sensing element and material surrounds the at least one electrical lead and defines a space around the at least one electrical lead so that when temperature gradients create push and pull, the at least one electrical lead moves within the space. The sensor assembly may further comprise a sleeve connected to the tube and surrounding the material. The sleeve may have an intermediate bent portion that the at least one electrical lead passes through, with a braided supply line connected to the leads, the braided supply line being arranged and configured within the bent portion to absorb movement of the two leads from temperature gradients. The lead can also extend through the sleeve forming a sinusoidal shape within the sleeve for absorbing movement resulting from temperature gradients.

Abstract: A pressure sensor including a housing with a sensing element therein. A communication passageway is formed in the housing. The sensing element is in fluid communication with an outside of the housing through the communication passageway. The pressure sensor is further provided with a compensating structure, so that when a contact force is increased due to occurrence of a volume expansion of a liquid passed into the housing through the communication passageway, the compensating structure is used to compensate the volume expansion. A plug may also be used with the pressure sensor. The pressure sensor is such that when the liquid within the pressure sensor has an increased volume due to being frozen, such increased volume can be compensated, so as to prevent the components of the pressure sensor from being damaged.

Abstract: A sensing device (100) senses a physical quantity of a fluid having a high temperature. A tube-like element (110) surrounds at least a part of a MI-cable (102) between a sensing end of the MI-cable and a sealing flange element (106) attached to the MI-cable. A major part of the inner surface of the tube-like element is at a predefined distance from the outer surface of the Mineral Insulated cable forming a gap (112) between the mineral insulated cable and the tube-like element. The tube-like element and gap increases robustness against thermal expansions and thermal shock due to rapid temperature change of the fluid.

Abstract: A joystick includes a mechanism for facilitating the changing of a grip assembly. An actuation mechanism moves a ram into a position where the operator can press down on a locking pin to release the grip assembly. The ram will be in a default position that does not interfere with the operations of the joystick during normal operation. A relatively low amount of force is used to place the ram into position as the force needed to press down on the locking pin comes from the operator. A small electromagnetic that does not interfere with the joystick operations can be used in the actuation mechanism.

Abstract: A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.
