A track system may include a track assembly and a support assembly. A track assembly may include a wheel receptacle. The support assembly may include a support member removable from and adjustably connected to the track assembly. The support member may include a wheel. The wheel may be adjustable to an engaged position in which the wheel engages the wheel receptacle. The wheel may be adjustable to a disengaged position in which the wheel is not engaged with the wheel receptacle.

A single axis slew driving system with integrated sensors and transducers including a housing defining a cavity, a rotor assembly rotatably mounted within the cavity supporting an axle with a gear plate affixed thereto and gear teeth positioned along a periphery thereof, a driving gear rotatably mounted in the housing meshing with the gear teeth, and a drive motor attached to the driving gear for rotation of the driving gear and one of: a thermocouple embedded in the housing to provide an indication of the temperature adjacent the driving gear; an absolute position sensing system including a movement tracking device mounted in the housing and extending into the cavity of the housing; limit switches mounted on the outer periphery of the housing; an integrated accelerometer and communication assembly; and an integrated torque routing solenoid mounted on an outer periphery of the housing.

The present invention relates to an automatic instant tent frame including: a head for collectively coupling a plurality of legs thereto; and the plurality of legs for providing a framework of an automatic instant tent, each leg having an upper pole and a lower pole coupled integrally to each other by means of a pole connector, wherein the head includes: a hub for collectively coupling a plurality of pole couplers thereto; the pole couplers each having one end portion coupled to one end of the upper pole and the other end pivot-coupled to a corresponding coupling wall of the hub; a stopper coupled to top of the hub; a compression spring fitted to a through hole formed on the center of a coupling pillar of the hub; coupling nuts disposed on top and underside of the stopper; and a coupling bolt fitted to the compression spring.

An excentric pin for an electronic throttle control assembly, which is used to adjust the default position of at least one spring used to control the position of a valve plate, where the valve plate is located in an opening of a housing in the electronic control assembly. The excentric pin is used to adjust the default angle of the valve plate to have an angular tolerance of +/0.10. The excentric pin is slideably pressed into an aperture of the housing of the electronic throttle control assembly, and turned using some type of driver. The electronic throttle control assembly may be a one-spring design, or a two-spring design, where the two-spring design requires only one spring pin and the excentric pin. Also, the excenter pin may be used to adjust the position of the sector gear, e.g., function as the lower mechanical stop to provide a minimum opening angle for low leakage, and a minimum opening angle to avoid throttle plate corking into opening of the housing.

A locking device and a locking method are provided for a tool holder of a rotary drilling rig. The locking device includes a sleeve, a locking pin, a movement system, and a control system. The sleeve and the locking pin are configured such that the sleeve engages around the locking pin with a form fit, such that the locking pin can be rotated in the sleeve about the longitudinal axis of the locking pin. As a result, the locking pin can be displaced laterally parallel to the longitudinal axis. The movement system has at least one electric motor and at least one shaft, wherein the shaft effects relative rotation of the sleeve and the locking pin by the force of the electric motor.

A vehicle seat back includes a lower seat back portion and including side frame members and an upper seat back portion including side frame members including a gear sector including a lower edge with sector gear teeth. Pivot connections pivotally connect the lower side frame members to the upper side frame members. A pinion gear with gear teeth is engaged with the sector gear teeth. A motor assembly is mounted to one or both of the lower side frame members and includes a motor and an output shaft driving the pinion gear in each of two rotational directions. The rotation of the motor in one direction, pivots the upper seat back relative to the lower seat back in a forward pivot direction and rotation of the motors in an opposite direction pivots the seat back relative to the lower seat back in a rearward direction.

A gear drive mechanism is provided with a gear drive pin provided at the second gear, a first movable member and second movable member configured to be able to move to the gear drive pin side, a first guide groove formed at the first movable member and engaged with the gear drive pin when making the eccentric member rotate toward a low compression ratio position, and a second guide groove formed at the second movable member and engaging with the gear drive pin when making the eccentric member rotate toward the high compression ratio position and wherein the mechanism makes the gear drive pin moving relative to a counterweight move along the first guide groove and the second guide groove so as to make the second gear rotate.

In a parking lock for an automatic transmission, an electrical parking lock actuator has an electric motor, a spur gear stage driveable by the electric motor, and a worm gear stage driveable by the spur gear stage. A worm shaft of the worm gear stage is connected rotationally conjointly to an output gear of the spur gear stage, and a worm gear of the worm gear stage is connected rotationally conjointly to a transmission-side parking lock shaft. The worm shaft is fixed in an axially displaceable manner in the output gear. A stop limits the pivoting movement of the worm gear when a parking lock position of the parking lock shaft is reached. A spring braces the worm shaft in an axial direction of the worm shaft against a holding mechanism which is situated in a stop position, in which the holding mechanism is fixed by an electrically energized electromagnet.

A linear actuator for driving an actuating element of an internal combustion engine of a motor vehicle has two scanning elements for scanning opposite sides of a guide cam. The guide cam has a protruding rib against which the two scanning elements are pre-tensioned to permit a play-free scan of the guide cam.

An improved self-engaging clutch having a carrier plate with one or more clutch actuator fingers formed into the carrier plate.
