摘要： An arrangement and technique for decoding optical wave division multiplexed Manchester Gray coded serial binary signals is disclosed wherein synchronization information is utilized to establish a preferred timing of bits of data and then the incoming signal is monitored to detect data bits appearing within prescribed bounds of permissible timing variation from the preferred timing. When a bit is detected within these prescribed bounds, it is reset to appear at the time at which it should have occurred according to the preferred timing.

摘要： An optically controlled fluid powered actuator is disclosed and includes a primary fluid valve positioning transducer which responds to optical binary coded control words to position a fluid. The actuator has a pair of opposed stacks of piezoelectric elements with the relative length of the piezoelectric elements in each stack being in the same ratios as the relative weights of bits in the control words. There are two sets of optically actuated electrical switches each responsive to control words to energize corresponding ones of the piezoelectric elements in an associated stack of elements. A first class lever has one end coupled to a controlling portion of a fluid valve and the other end interposed between the stacks of piezoelectric elements so that the lever can translate motion of elements in a piezoelectric stack into fluid valve actuation. A fluid powered electrical generator provides the sole source of electrical energy for the piezoelectric elements. A pair of optical fibers convey the optical binary coded control words in the form of a wavelength division multiplexed optical signal to corresponding ones of the sets of switches.

摘要： An electro-optic speed sensor for sensing the speed of rotation of a rotating sending unit which includes an optical switch transducer for sensing disturbances in a magnetic field caused by the passage of a rotating magnetic sending wheel on the rotating member. The optical switch transducer uses a Faraday material and provides its signal by rotating the polarity of polarized light from a first source of light having a first bandwidth while allowing a second source of light having a second bandwidth to pass through unaffected. The first and second sources of light are thereafter, reflected within the transducer. The disturbances in the magnetic field generate an optical signal resulting from changes in the Faraday rotation. A photodetector receives the light from the first source to develop an operational signal corresponding to the speed of rotation of the rotating member and light from the second source to check on the continuity of the sensor system.

摘要： A sensor for use in an optical temperature detector system having a birefringent element made of a single crystal metal oxide plate. A broad band light spectrum is transmitted through a first linear polarizing element to create a linearly polarized wave. The linearly polarized wave on passing through the single crystal metal oxide plate decomposes into first and second orthogonally polarized waves. Propagation of the linearly polarized wave through the birefringent single crystal metal oxide plate introduces a temperature dependent phase shift between the two waves. Thereafter, a second linear polarizer combines the first and second orthogonally polarized waves to create a modulated light spectrum having a fringe pattern, the fringe pattern being a function of the current temperature experienced by said birefringent element. A fiber optic cable connected to the second linear polarizing element carries the modulated light spectrum to an opto-electronic interface where the fringe pattern is extracted and a computer compatible signal is generated for a CPU to accurately indicate current environmental temperature conditions up to 1000.degree. C. experienced by the single crystal plate crystal in the birefringent element.

摘要： An optical spectral analyzer (10) for receiving an input beam (30) through a multi-mode optic fiber (28). The input or beam (30) has a predetermined spectral band width. The random individual spectral components of the beam (30) are dispersed by a grating (40) to generate a spectrum (42, 42' . . . 42.sup.N). A detector (52) senses the magnitude of the elements in a reflected focused spectrum (50, 50' . . . 50.sup.N) to recover the information placed on the optic fiber (28) at a remote location by a spectrum encoding device.

摘要： Control methods for vapor compression systems and multiple-load vapor compression systems having one or more refrigeration loops include selecting a desired set-point temperature range for a load temperature at one or more load locations. The vapor compression system is then operated to transfer heat from the one or more load locations to a rejection location. While the vapor compression system is operating, a control apparatus continually adjusts various parameters. A capacity of an adjustable-capacity compressor is adjusted to maintain with respect to an evaporator load a maximum low-side pressure of the refrigeration loop as measured by a first sensor. An adjustable rejection capacity of a rejection apparatus is adjusted to maintain a minimum high-side pressure of the refrigeration loop as measured by a second sensor. An adjustable opening of an expansion valve is adjusted to maintain a load temperature measured by the third sensor within the desired set-point temperature range.
