    摘要: A projection apparatus is formed employing a solid state light source having either an associated or integrated sensor to monitor a thermal condition of a region of the solid state light source. The sensor is equipped to output a signal indicative of the thermal condition of the monitored region. In various embodiments, a controller is also provided to conditionally initiate one or more thermal management actions based at least in part on the thermal condition of the region as indicated by the signal.

    摘要: A miniature isometric joystick is disclosed for receiving manual user input to effect directional control such as controlling cursor movement on a computer display screen or controlling movement of an apparatus such as a machine or robot. The joystick is arranged to fit between the existing keys in a computer keyboard. The joystick includes a preloading spring for compressing the assembly together, thereby biasing the force sensors so as to neutralize manufacturing variations and control electrical and mechanical null zones. An integrated switch is provided in the joystick for detecting an external force applied by the user's fingertip. The switch unobtrusively detects when a user is pointing, thereby allowing a control system to measure pointing system bias signals while the user is not pointing. This permits the control system to automatically correct for drift, without requiring additional keyboard space for a separate switch to enable the pointing device.

    摘要: A projection system. The projection system includes a projector, a projector holder, and, optionally, a screen. When included, the screen has at least a deployed configuration in which a viewing portion of the screen is substantially planar. The projector includes a wide-angle lens system to selectively project display images onto the projection screen or other viewing surface. The projector holder supports the projector and is moveable relative to the projection screen or other viewing surface. The projector holder has at least an operating position at which the projector is supported for projection onto the projection screen or other viewing surface.
