摘要： A positioning system for locating objects in places where standard Global Position System signals do not penetrate. A first embodiment uses a GPS receiver and a clock recovery unit. A computer receives the positional information and accurate time information. The computer calculates new orbital data for at least four pseudosatellites. The pseudosatellites are antennas positioned in an interior or shielded space and function to send pseudosatellite data to a receiver. In a second embodiment, the positions of the pseudosatellites are provided to the computer without the use of a GPS receiver. An accurate clock signal is also provided. The computer calculates orbital data for each pseudosatellite and transmits the time signal and ephemeris data for each pseudosatellite. The time signal is delayed for each pseudosatellite to account for propagation delays due to different connecting cable lengths.

摘要： An autorefractor system in an ultra-compact package is described for rapidly and objectively measuring the refractive state of the eye. The autorefractor detector system, in conjunction with a secondary light source, uses one photodetector such as a charge coupled device (“CCD”) or one photodiode, to intercept a light beam at two distances from a secondary retinal light source created by one relay lens, one pupil emitter conjugate lens and one pupil detector conjugate lens, as well as a field lens. The signals produced by the photodetector are used to determine the full spherocylindrical refraction of the eye. A novel illumination and imaging system provides multiple capabilities to image the eye, control accommodation, and acquire and maintain optical alignment, while obtaining other measurements of the eye.

摘要： A method is disclosed for accurately registering read-write heads on a magnetic storage medium. It includes the steps of ascertaining fractional departures of track locations from the nominal locations; providing a control for a motor connected to move a read-write head capable of detecting and storing fractional values of the nominal channel spacing; and coupling the control digitally to a stepping motor or servomotor so as to drive the read-write head accurately to the actual position of any selected track. Also, apparatus for practicing the method, various apparatus being disclosed.

摘要： An electrical circuit comprising means for receiving an input signal for encoding or modulating and amplification. Multiple amplification stages including at least one transconductance amplifier are provided. There are means for having the input signal modulate the oscillator constituted by the multiple amplification stages to provide a 360.degree. phase-shifted signal at a predetermined frequency. Gain control means are also provided for developing level for permitting oscillation under conditions including at least the conditions of turn on of the circuit and other operating conditions. The gain control means includes a transistor and resistor network for adjusting the gain to sustain the oscillation. The transistor and resistor also regulate amplification of an intermediate stage of the amplifier. The preamplifier directly converts an EKG and/or other signals to linearized control currents which modulate the oscillator.
