A lift truck employs forward and reverse pedals connected through respective cams having different upper and lower cam profiles that engage to provide asymmetric reciprocal pedal motion. For example, first pedal depression causes a first cam upper profile to engage with a second cam upper profile and cause increased elevation of a second pedal, and first pedal depression causes a first cam lower profile to disengage with a second cam lower profile associated with the second pedal, such that first pedal depression is greater than the increased elevation of the second pedal.

A fixture assembly includes a first rail, a second rail coupled to the first rail, a first mount configured to support a first panel, a column coupled to the second rail, and a second mount movably coupled to the column. The first mount is movably coupled to the first rail to allow the first mount to move along the first rail in a first direction. The fixture assembly further includes a first servomotor coupled to the first mount to allow the first mount to rotate about a first axis. The fixture further includes a second servomotor coupled to the second mount to allow the second mount to rotate about a second axis. The fixture assembly includes a controller programmed to control the first servomotor and the second servomotor.

A stability and command augmentation system for controlling an aircraft, comprising: a first member moveable by a pilot input device to a first position defining a first input; a second member moveable to a second position associated with a second input; and an adder device configured to add the first and second inputs and supply an output signal defining a command for an element to be controlled of the aircraft; the stability and command augmentation system comprises: a casing, a first and a second piston integrally movable with one another inside the casing and operatively connected to the second member; and control means configured to exert a first force on the first piston and a second force on the second piston; the second force is independent of the first force.

Disclosed is an apparatus for varying the direction of travel of a vehicle, including a rotatable unit operable by the vehicle driver, in particular by gripping, to vary the vehicle's direction of travel, and a support, or hub for rotatably supporting the rotatable unit, having a respective longitudinal axis and connected fixedly to the vehicle. The support for rotatably supporting the rotatable unit has a unit for transferring movement of the rotatable unit to a corresponding unit for controlling the vehicle's direction of travel, such the rudder of the water-borne vehicle, through a corresponding transmission. The transfer unit transfers movement of the rotatable unit, or steering wheel to the unit for controlling the vehicle's direction of travel, in particular through the transmission to the self-same controlling unit, preferably through the rotary transmission shaft, with a transmission ratio of 1:1.

A winch assembly includes a first bracket configured to be positioned at a first lateral side of a vehicle, a second bracket configured to be positioned at a second lateral side of the vehicle, a first actuator and a second actuator configured to be coupled to a winch free spool device, a first bushing coupled to the first actuator, a second bushing coupled to the second actuator, and a lever arm coupled to both the first actuator and the second actuator and configured to interface with the winch free spool device. The first actuator and the second actuator are moveable to position the first bushing into engagement with the first bracket or position the second bushing into engagement with the second bracket to selectively lock the winch free spool device in an engaged position.

An interactive fish tank system is provided, including: a nozzle array provided in a water tank, wherein a plurality of bubble nozzles from which bubbles are emitted are arranged in the nozzle array; a computing device configured to receive user action information inputted from at least one user action input device, generate bubble conversion information by which characteristics of the user action information are expressed as bubbles generated from at least one of the plurality of bubble nozzles, and generate a control signal for supplying air to emit bubbles corresponding to the bubble conversion information; and an air injection device connected to the plurality of bubble nozzles through hoses, wherein the air injection device supplies air to at least one of the plurality of bubble nozzles based on the control signal.

Rudder pedal and brake inceptor devices are described that utilize a straight-line mechanism and rotary joints to achieve straight line motion in a compact volume. The devices can include four or more bar linkages that translate forward motion of a pedal into a rotary motion of a common shaft, such that forward motion of one pedal causes the other pedal to retract while allowing for yaw motion control of the aircraft.
