Abstract: An automated slide stainer with slides mounted in a horizontal position on a rotary carousel. Reagents and rinse liquids are automatically dispensed onto tissue sections or cells mounted on slides for the purpose of performing chemical or immunohistochemical stains. The rinse liquids are removed by an aspiration head connected to a source of vacuum. Individual slides or groups of slides are supported on flat heating stations for heating to individual temperatures. Temperature control electronics on the carousel are controlled by a user interface off of the carousel.

Abstract: An electronic stethoscope having several modes of operation to process acoustic signals to provide filtered signals useful for diagnosis. In one mode of operation the stethoscope substantially provides only acoustic signals generated by biological activity of the heart. In another mode of operation, the acoustic stethoscope substantially provides only acoustic signals generated by biological activity of the lungs. In another mode of operation, the electronic stethoscope disproportionately amplifies abnormal heart sounds and normal heart sounds to enhance diagnosis of heart abnormalities. The electronic stethoscope is operated in a manner similar to a conventional acoustic stethoscope and has similar spectral characteristics, thus allowing a user with acoustic stethoscope experience to easily use the electronic stethoscope.

Abstract: A therapeutic subliminal imaging system wherein a selected subliminal message is synchronized with and added to an existing video signal containing a supraliminal message. A television receiver or video recorder can be used to provide the supraliminal message and a video processing circuit varies the intensity of that perceptible message to incorporate one or more subliminal images.

Abstract: A stepping motor control system which uses a closed-loop lead angle control technique wherein a programmably selected lead angle signal is combined with a signal representing the position of a step motor shaft so as to provide a coil state excitation signal for the coils of the stepping motor, the shaft thereof being rotated in response to the coil state excitation signal. The lead angle signal can be modulated in accordance with a selected duty cycle so as to assume two adjacent lead angle values during each modulation cycle. The system can also be arranged to permit the use of open-loop control using a suitably programmed externally supplied coil state excitation signal, the latter being capable of similar modulation as described above with reference to lead angle modulation.
