  • Patent number: 5486700
    Abstract: Proximity controls for controlling the proximity of a gamma camera to a patient during a scan of the patient. The proximity controls consist of two spaced apart energy screens, each comprising 200 beams, parallel to and spaced from the detector of the gamma camera. When neither screen is interrupted, the camera is moved towards the patient. When both screens are interrupted, the camera is moved away from the patient. When only the screen farthest from the detector is interrupted, the camera is braked so as not to move away from or towards the patient.

    Abstract: A signal processing method for detecting a point of change from a first signal level to a second signal level, outputted from a line sensor having a photoconductive bit element array including setting a threshold level between the first signal level and the second signal level. A pair of bit elements are detected which have outputs that are larger than and smaller than the threshold level. A first line is determined based on the outputs of the pair of bit elements or a pair of bit elements which have a specific relationship to the above-mentioned pair of bit elements. A zero-cross bit element located at an intersecting point of the first line with a zero level is obtained. A second line, which has an inclination angle that is smaller than that of the first line, is determined based on the outputs of the zero-cross bit element and a bit element having a specific relationship to the zero-cross bit element or the outputs of a pair of bit elements having a specific relationship to the zero-cross bit element.

  • Patent number: 5485072
    Abstract: A method and apparatus is provided for operating a permanently excited single-phase alternating current machine, otherwise known as a transverse flux machine, which allows optimal exploitation of the machine and economical design of the converter. A terminal voltage is applied to the machine, the shape of which is defined by the characteristics of the machine. The waveform of the terminal voltage converts from a sinusoid to a square wave, with a maximum voltage equal to the maximum available voltage, at defined switch-over times. Based on the switch over times, the resulting terminal voltage wave can be square, completely sinusoidal, or a combination of both.
