Abstract: A temperature radio telemetry system combined with an alarm clock, intended for home settings. The alarm clock can be a digital alarm clock, or a radio alarm clock, or a computer running an alarm clock subroutine, devices nearly ubiquitous in private homes. The telemetry receiver is integrated with the alarm clock in a bedside enclosure, or is plugged in the parallel or serial port of the computer. The telemetry system principally detects the skin temperature elevation in infants and children with fever, especially at night, and subsequently triggers an alarm for the parents. The system can also detect the peripheral skin temperature drop in diabetic patients with early symptoms of hypoglycemia, or the small temperature rise associated with ovulation. The telemetry link has several fail-safe attributes, is operable without a license, and resists to interference by using a running median data smoothing method. The transmitter is simple, inexpensive, and child-safe.

Abstract: A two-way flexible valve to control or interrupt the flow of a pressurized medium. The valve is a polymeric semi-rigid tubing hyperflexed until its material has yielded in an irreversible manner and created a kink. Ulterior flexions of the tubing tend to occur about the preferred axis set by the kink. An acute angle closes the valve by crimping the lumen shut, whereas an obtuse angle opens it in some proportion of the angle. One end of the kinked valve tubing is held on a support and the other end is fastened to a lever hinged on pivot pins. The distance between holding points and the valve kink is several times the diameter of the valve tubing, and the axis of the kink is collinear with that of the hinge, both factors reducing sideload stress in the valve material, increasing its lifespan. An elastic member holds the valve closed and a flexible actuating line acting against the elastic member opens the valve in some proportion of its pull.
