In some embodiments, a protective apparatus for rotary control knobs may comprise a cover adapted fit over a rotary control knob; a knob cavity internal to the cover adapted to provide space for the rotary control knob to rotate about; and an access aperture located on the surface of cover member and adapted to provide limited user access to the rotary control knob. The cover member may be configured to encase or surround a control knob. The apparatus may further comprise a plate which may be integrally formed or molded to the cover and which contains a control shaft aperture adapted to receive the control shaft of a rotary control assembly. Once a control shaft is inserted through the control shaft aperture, a fastener may be secured to the control shaft over the plate, thereby securing the apparatus to the control shaft.

A control element for a vehicle is designed to change between a parking state and a driving state. In the parked state, the control element is designed to enable a driver to switch the vehicle from a parked state to a travel state. The control element also enables the vehicle driver to freely select a gear of the vehicle by changing from a parking state into a drive state.

Provided is an operating device comprising: an operation part which is inserted into an insertion hole portion of a glass part and has a locking protrusion portion having a protruding shape on the side surface thereof; and a locking rotation part which is disposed in a position opposite to the side surface of the operation part so as to allow or lock the movement of the locking protrusion portion, the locking rotation part comprising: a frame part having an inner hole portion into which the operation part is inserted; and a hollow hole part rotatably disposed in the frame part and communicating with the inner hole portion.

The invention relates to a force application device for a control stick of an aircraft, said stick comprising a control lever that is connected to a motor comprising a drive shaft, said device having: a first pin connected to the drive shaft, a housing, a second pin secured to the housing, an electromagnet secured in relation to the housing, a movable actuator which comprises a magnetic material such that said actuator can be displaced depending on a supply of current of the electromagnet, and means for clamping the first pin and the second pin which comprise a first tooth and a second tooth, said device having an operating configuration in which the electromagnet is active and the actuator separates the teeth away from the first pin and the second pin, and a blocking configuration in which the electromagnet is inactive, with the first tooth and the second tooth coming into contact with the first pin and the second pin.

A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.

The present invention is an Electric servo system which controls and automates gate openings based on GPS speed and position data that results in precise and reliable modern variable and constant rate application. The Electric servo system also allows for Mechanical gate linkages to remain intact, resulting in few changes to the aircraft and redundancy of emergency components. A Mechanical input connect/disconnect is used to effortlessly transfer between the automated Electric servo system and the Mechanical gate system.

A method for controlling an aircraft includes determining photographing information related to a photographing object, the photographing information indicating an occupying scope of the photographing object in an image to be captured. The method also includes controlling the aircraft to fly to a photographing location based on the photographing information.

A multidirectional input device includes a frame, a plate-shaped base below the frame, a load detector provided on the frame or the base, and circuitry. The frame stores part of a tiltable operation stick and a tilt detector. The circuitry is configured to output an output signal representing the direction and the magnitude of an operation on the operation stick, based on the angle detection value of the tilt of the operation stick detected by the tilt detector and the load detection value of a load applied to the frame detected by the load detector. The circuitry is configured not to output the output signal or to output the output signal that sets the magnitude of the operation to zero, when the load detection value detected by the load detector is less than a predetermined threshold.

A safety knob assembly for actuating a burner is provided. The safety knob assembly includes a dial, the dial includes at least one alignment hole, an interlock disk, the interlock disk includes at least one locking pin, the at least one locking pin having an outer diameter less than then the inner diameter of the at least one alignment hole, a safety post, the safety post connected to the dial and the safety post including a locking hub, the locking hub connected to a switch post, a spring, the spring sized such that the inner diameter of the spring is larger than the outside diameter of the safety post, the spring positioned on the safety post and positioned between the dial and the locking post, wherein the at least one locking pin of the interlock disk engages the at least one alignment hole of the dial as a bottom surface of the dial approaches a top surface of the interlock disk, wherein the interlock disk engages the locking hub as a bottom surface of the interlock disk approaches the locking hub, and wherein the burner is actuated as the dial, the interlock disk, the safety post and the locking hub are positioned to rotate the switch post relative to the burner to allow the flow of energy from an energy source to the burner.

The presently disclosed quick adjust slide knob addresses the ‘Backing-Off’ problem present with various conventional nuts. The quick adjust slide knobs can be quickly positioned along a threaded rod by applying pressure to an exposed surface of a partially threaded nut. When the knob is placed against a work surface and the user releases pressure from the partially threaded nut, the thread pattern on the partially threaded nut meshes with the matching thread pattern on the threaded rod. The device can then be twisted, which will translate the device along the threaded rod, to apply a larger load to the work surface. The threaded rod may include one or more key-ways shaped to allow a locking tab housed within the knob to stop the device from freely disengaging the threaded rod to protect a user from potential injury caused by the fastener unexpectedly backing off and disengaging.
