摘要： A hinge assembly includes a pivoting body attached to a base with a front surface. The pivoting body has a front end and rear end and at least one friction reducing member biased rearwardly against the front surface of the body. The friction reducing member is retractable relative to the pivoting body substantially parallel to the direction of the bias. The front surface has an inclined portion and an apex. When the pivoting body is in a rest position the at least one friction reducing member is maintained at the apex. The pivoting body is pivotable in a first direction to an activation that causes the friction reducing member to roll along the inclined portion with the friction reducing member retracting in the forward direction against the bias. When force is removed from the pivoting body in the activation position, the bias against the contoured front surface returns the pivoting body to the rest position via indirect forces.

摘要： A control interface includes a sensor having a sensing field projecting adjacent to one or more input devices such as switches actuated by an operator. The control interface detects the profile, position, and/or motion of objects in the sensing field and compares these to stored values of profile, position, and/or motion representing a valid operator attempt to actuate the input device. Upon detection of a valid attempt to actuate the input device, the control interface generates a control signal that may be communicated to an operator or to connected equipment. The control signal is generated before operator makes contact with the input device. The control signal may be used to provide a pre-activation alert to the operator with identifying the input device about to be actuated. Alternatively, the control interface may disable input devices until a valid attempt to actuate the input device is detected, and the control signal is used to enable the input device.
