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:
An apparatus, system and method for stabilizing components is provided. In some embodiments, an apparatus for positioning an optical component relative to a frame is provided including a stabilizer. The stabilizer may be configured to be coupled to the optical component and the frame, wherein in a first configuration the stabilizer is configured to enable select adjustment of the optical component in at least two directions and in a second configuration a position of the optical component may be fixed.

Embodiments of this invention include a system, method and apparatus for combining the light paths of a plurality of colored light emitting devices into a single light path with two reflecting devices and an optical combiner assembly in a projection system.
摘要:
Embodiments of the present invention include an apparatus, method and system relating to a projection illumination source pulsing one or more light emitting devices a plurality of times per frame.
摘要:
A method of controlling power provided to one or more light emitting diodes in a projection system comprises measuring light output from the one or more light emitting diodes. Based at least upon the measured light output, the power to at least one of the light emitting diodes is modified.
摘要:
A multimedia projector employing a color wheel housed within a shroud uses a light guide that is integral with the shroud and formed as an aperture extending through the shroud to transmit light from the color wheel to a photo detector that detects a particular color or colors of light to provide an index mark signal to a display controller to synchronize red, green, and blue image data with the associated color wheel filter segments. A reflector is located at an exit end of the light guide to reflect the light through a dichroic filter positioned on the shroud toward the photo detector on a circuit board.
摘要:
A speed governor is enclosed within a generally cylindrical housing which defines an interior cylindrical surface. A rotor is rotatably supported within the enclosure of the housing and is coupled to a power coupling belt by a pulley formed in the rotor shaft. A pair of weighted arms are pivotally secured to the rotor forming a pair of centrifugal counterweights. A coil spring is commonly coupled between the counterweights to provide a drawing force urging the counterweights to a collapsed inward position. Each counterweight supports a friction pad on its outer surface facing the cylindrical surface of the governor housing.
摘要:
A push toy having a wheel housing rotatably supporting a pair of wheels with an impeller within the housing actuated upon rotation of the wheels, the impeller coacting with the interior of a generally transparent, continuous loop tube formed partially within the handle with a plurality of colored spheres therein, rotation of the impeller moving the string of spheres up the tube to the apex thereof, whereupon the spheres drop under the force of gravity. The toy may be operated in forward or reverse directions.
