Abstract: A nasal shaper configured to be introduced into a nose of a subject, the nasal shaper including two tubes suitable for each being introduced into a nostril of the nose, connected together at their lower ends by a connecting bridge and a plate attached to the connecting bridge and extending opposite the connecting bridge relative to the tubes, the plate being configured to exert a pressure on the philtrum of the subject when the tubes are each introduced into a nostril of the nose.

Abstract: A peristaltic pump controller provides control of a positive displacement pump as either an uncalibrated or calibrated flowmeter, or a calibrated dispenser. A calibration constant is calculated, after the pump is primed, to determine the amount of volume output produced by an increment of angular rotation of the pump. The constant is determined during a calibration operation where an arbitrary calibration volume is metered. The controller has a low flow and high flow mode where the low flow mode provides a higher resolution for dispensing. The flow mode of operation is determined by the value of the calibration constant and is automatically set when the constant is calculated. DUring a dispensing operation, the controller will meter fluid to within a predetermined amount of the final volume dependent upon the speed of the pump motor and then dribble in the remaining amount of a batch for precision.

Abstract: An electronic organ includes digital circuitry for automatically enabling in a sequential manner a plurality of gates to pass tone signals to a corresponding plurality of keyers. The sequential enabling is separately controllable by an arpeggio circuit, a glissando circuit, and a strum circuit. The digital circuitry includes an octave counter and a tone counter both of which are stepped by a quadrature clock to sequentially enable the gates. The quadrature clock can be stopped to cause a count to be held under control of multivibrators which adjustably control the tone interval and the repeat interval. The repeat multivibrator can be automatically synchronized under control of a key down detector or a rhythm generator.
