摘要： A three phase motor conversion and monitoring circuit converts a three phase motor to be started and run on single phase line power. During motor start-up, the circuit connects a start capacitor across a first input pair of the motor via a normally closed relay contact. The circuit includes a power supply connected across a first motor input pair which powers both a voltage monitor connected across a different input pair and a phase sequencing detector. When normal run voltage is detected across the first and second input pairs, and if and only if the phase sequencing detector has detected a normal phase sequence indicating that the motor is rotating in the correct direction, the relay is operated to open the normally closed contacts and to remove the start capacitor from the motor circuit.

摘要： A method and apparatus employing optical type techniques are provided for use in reliably sensing the juxtapositional relationship between successively relevant portions of an object and a sensing unit that are relatively movable, in accurately maintaining a predetermined juxtapositional relationship between such portions of the object and the sensing unit during relative movement therebetween, and, when appropriate to the application, in also faithfully sensing other information carried by such portions of the object. The method and apparatus are characterized by eliminating any need for mechanical engagement between the sensing unit and the portions of the object to which the sensing unit responds and by utilizing only optical type coupling between such portions of the object and the sensing unit for the transfer of all information to be acquired by the sensing unit from the object. An important and currently preferred application of the method and apparatus, in which both positional and other information are sensed, is in playing ordinary phonograph records without inducing wear thereto in the course of sensing the recorded information. In the context of the mentioned application, both information for controlling the juxtapositional relationships between the record and the sensing unit with respect to both spacing and groove tracking and information with respect to the recorded audio material are sensed. In other contemplated applications, the sensing of only that information needed for controlling juxtapositional relationships may be desired, or the other information to be sensed may represent digitally encoded data, etc.

摘要： A method for error detection and correction of a memory, preferably a flash memory that utilizes existing on-chip circuitry to implement the error correction and detection process is disclosed. The present invention is able to detect and correct single bit errors, while detecting multi-bit errors in data storage circuitry. The method is embodied in a software routine, which when actively operative, uses a multiply accumulate circuit (MAC) and on chip cache located on memory controller circuitry for error correction of errors incurred through the storage of data to a storage device.

摘要： A method and device are disclosed for the detection of the relative percentage of at least one light absorber in the blood stream of living tissue. The method and device are based upon the employment of a narrow band width amplifier and pulses of different wavelength light sources wherein the frequency of the pulses of the light sources are selected so that a large component of the signal falls within the frequency of the narrow band amplifier, so that there is reduced likelyhood of interference from extraneous electromagnetic waves.

摘要： An instrument housing having an improved means for storing a roll of paper of selected width and maximum diameter for use by a printer in which the housing has a rectangular opening in the top adjacent the housing front and a rectangular opening in the front forward of and below the opening in the top. A paper trough is positioned within the instrument housing below the top opening and rearwardly of the front opening, the trough having an open top and having opposed parallel sides and a rearward wall and a bottom wall which merge into a quarter circular integral intersection, the radius of curvature of the intersection being about one-half of the maximum diameter of the paper roll for which the trough is dimensioned. A trough gate forms a front wall, the trough gate having a downwardly extending inner surface curved at the lower portion thereof toward the trough back wall at a radius of curvature substantially equal to that of the radius of curvature of the intersection of the trough rearward and bottom walls, and the trough gate having a bottom wall spaced slightly above the trough bottom wall providing a slot therebetween whereby when a roll of paper is positioned within the trough the free end of the paper may exit the trough through the slot. An electrically actuated printer mechanism is positioned in the housing forward of the trough gate, the printer having means to receive the paper for pulling paper through the slot as the printer functions.
