Abstract:
A microprocessor based engine control system including an engine control unit for producing a plurality of pulse width modulated output signals of programmable frequency. The pulse width and frequency of each output is contained in a control word provided to the engine control unit. The control word contains a pulse width number and a frequency code. The control unit includes a free-running counter and logic means which switches the output signal to one level when the number of stages of the counter defined by the frequency code are all zero and switches the output signal to a second level when the content of the aforementioned number of counter stages is greater than the pulse width modulated number.
Abstract:
A motion capture system includes motion capture cameras positioned in various locations and orientations with respect to a motion capture volume. The motion capture system includes a host computing device that is operatively coupled with the motion capture cameras. The host computing device remotely controls operation of the motion capture cameras to record movement within the motion capture volume. At least one of the motion capture cameras includes a user-interface that is operable by a user to remotely initiate a control operation of the host computing device.
Abstract:
An air core gauge method and apparatus are disclosed. The apparatus receives an input signal and comprises a gauge device and driver circuit for driving the gauge device. A detection circuit detects transitions in the input signal and provides a control output in response to detected transitions. A power control circuit, responsive to the control output, provides a 100% duty cycle power signal to the driver circuit during detected transitions and otherwise provides a power signal with a duty cycle less than 100% to the driver circuit so that the average power consumed by the gauge is reduced and the operating temperature of the gauge is reduced.
Abstract:
A system for controlling operation of a computer. The system includes, a sensing apparatus configured to obtain positional data of a sensed object controllable by a first user, such positional data varying in response to movement of the sensed object, and engine software operatively coupled with the sensing apparatus and configured to produce control commands based on the positional data, the control commands being operable to control, in a multi-user software application executable on the computer, presentation of a virtual representation of the sensed object in a virtual environment shared by the first user and a second user, the virtual representation of the sensed object being perceivable by the second user in a rendered scene of the virtual environment, where the engine software is configured so that the movement of the sensed object produces control commands which cause corresponding scaled movement of the virtual representation of the sensed object in the rendered scene that is perceivable by the second user.
Abstract:
Isopropyl alcohol is dehydrogenated to acetone by contact with a catalyst having improved selectivity and activity which comprises a mixture of copper, zinc and chromium supported on an alpha alumina carrier.
Abstract:
A motion-capture system is provided. The motion-capture system includes a host computing system and a plurality of motion-capture cameras that are operatively coupled with the host computing system. Each of the motion-capture cameras is disposed in a different location and orientation relative to a motion-capture space and includes a marker-tracking optical filter to provide a marker-tracking mode and thereby relatively enhance light from markers on a moving body in the motion-capture space. One or more of the motion-capture cameras is remotely controllable to selectively interchange the marker-tracking optical filter with a scene-view optical component, so as to selectively transition the motion-capture camera between the marker-tracking mode and a scene mode, in which light from the markers is less enhanced than in the marker-tracking mode.
