摘要： An optical fingertip tracker, which may be a pseudo trackball, responds to the motion of the texture on one of the user's digits pressed against an image input aperture to produce motion signals processed within an appliance to be controlled. The appliance may have a minimal GUI, such as an LCD display having only a modest number of low resolution pixel locations and/or preestablished characters or icons. An appliance control parameter is set or adjusted in response to translation of the fingertip along a particular axis. E.g., to enter a parameter value (volume) a changing bar graph can be displayed. The display might even be omitted; to set the tone control of an audio appliance it can be sufficient to simply adjust the tone until the result is as desired. A numeric display of control parameter digits may be desirable, as when moving the fingertip tunes a receiver. There can be several particular axes along which fingertip movement changes an associated appliance control parameter. Other appliances can include character recognition of input characters traced by the fingertip. A pressure sensitive switch coupled to the fingertip tracker can serve as a delimiting mechanism useful in ratification of interpreted results and in editing strings that have been input. Excursions is a loss-of-correlation signal can be detected and interpreted as tapping the image input aperture with the fingertip. Such “taps” and “double taps” can be defined, and have selected meanings associated therewith that may be used in conjunction with, or in place of, the pressure sensitive switch.

摘要： An injector for a gas chromatography system resistively heats an included cold trap by magnetically inducing a high-frequency current therethrough to inject absorbed analyte into a gas chromatography separation column. The injector includes a flow controller that is set initially to load analyte into the trap. A heater and a two-stage Peltier cooler are used to establish a sharp trough-shaped temperature gradient along the cold trap so that analyte loaded into the cold trap is absorbed only at a relatively cold "focussing" zone of the trap. Once the analyte is focussed, the flow controller is set to direct released analyte into the column. The magnetic-field generator includes a capacitor that is discharged to initiate cold-trap heating. An inverter converts the discharge to a 100,000 Hz waveform through a transformer primary coil. A magnetic core delivers the resulting alternating magnetic field through the cold trap. The resulting AC current resistively heats the cold trap, volatizing analyte components so that they are injected into a gas chromatography column. The relatively modest power requirements for this compact arrangement provide for a practical cold-trap injector so that higher spatial resolution and greater effective sensitivity are achieved in the context of small-bore gas chromatography.

摘要： A method and apparatus for increasing detector sensitivity in a Capillary Zone Electrophoresis detector is disclosed. The present invention employs a unique cell, fabricated directly into a separations capillary, that increases both the flux and the path length of the ultra-violet light employed in an absorption measurement. The cell employs controlled geometric contours and osmotic pumping to prevent laminar mixing and turbulence. This novel design maintains the resolution of the parent biological separations instrument, while affording an order of magnitude enhancement of in sensitivity. A narrow bore capillary includes an injection end and an output end. Each end is placed in a reservoir containing a buffer solution and a sample of solute. The solute comprises at least one unknown constituent component. An electric field is imposed across the buffer solution and solute in the capillary by a power supply coupled to leads and electrodes. A source of ultraviolet light illuminates a novel cell within the capillary and a sensor measures the absorbance of radiation by the solute to detect the constituent components. A computer may be coupled to absorbance detection circuitry to analyze and display the results of the identification procedure.

摘要： A microminiature valve having radially spaced, layered spider legs, with each leg having first and second layers of materials having substantially different coefficients of thermal expansion. The legs include heating elements and are fixed at one end to allow radial compliance as selected heating of the legs causes flexure. Below the legs is a semiconductor substrate having a flow orifice aligned with a valve face. Flexure of the legs displaces the valve face relative to the flow orifice, thereby controlling fluid flow through the orifice.

摘要： A robotic camera dolly system includes a motorized dolly which rolls freely across a studio floor under computer control, the dolly carrying a camera. Targets are provided on the floor at various locations from which camera shots are to be taken. The dolly is moved from one target to the vicinity of another target according to a learned sequence of movements controlled by a remote dolly computer. The learned sequence of movements is taught with the aid of a joystick, and the motions are replayed based on dead reckoning. In order to correct translational and angular errors in the position of the dolly at the destination target, optosensors are provided on the dolly for use in detecting and reorienting the dolly relative to the destination target. The open loop control of dolly movement can be taught with a control stick and the motions replayed based on dead reckoning.

摘要： A method and apparatus for converting a tri-state logic signal into a two-state logic signal accurately and repeatably for purposes of signal measurement. In particular, the method and apparatus deal with how the third, or high impedance state is translated into a high or a low state. This is accomplished by including a resistor of a selected value to form a voltage divider with the resistance of the path through which the stray capacitance of the circuit under test charges during these intervals. Thus, the level of the final voltage charge is limited to a selected voltage that is intermediate the high and low state threshold voltages of that circuit. The initially conditioned signal, now a true tri-stage signal, is next applied to two threshold detectors, whose outputs in turn are applied to a state machine. This combination generates a repeatable two-state signal by identifying each occurrence of the third state as the last previous high or low state, i.e., the output of the conditioning circuit does not switch to the other state until both thresholds have been crossed by the signal in either direction, at the clock time. The resultant signal from the conditioning circuit has only two predictable and repeatable states, the low and the high states.

摘要： An electronic device able to detect a user in close proximity. The device may be a wireless data input device, for example, a radio frequency computer mouse. The device has power management features that do not require complex hardware or software to implement. For example, an antenna that is normally used for radio transmission is monitored. The power management features of the electronic device are able to detect a change in an operating characteristic of the antenna that is indicative of a user in close proximity thereto. For example, when the user touches a computer mouse, the resonant frequency of a circuit comprising the antenna changes due to capacitive loading of the antenna. The power management features cause the electronic device to be operated in a sleep mode or a radio transmission mode, depending on whether the user is detected.
