Skin temperature radio telemetry and alarms
First Claim
1. A temperature telemetry and alarm clock combination comprising;
- (a) a radio transmitter periodically transmitting a generally brief signal, whose relatively long period is a function of a measured temperature,(b) an alarm clock, as a functional unit that keeps the time of day, that can show the time of day on a display, that has a settable alarm time, and that can sound an alarm when the time of day reaches the set alarm time,(c) a radio receiver able to receive and condition said signal from said transmitter,(d) a programmable computing device, functionally connected to said alarm clock and said radio receiver, running an algorithm that determines the time of occurrence of said signals, calculates the period of successive signals, decodes temperature from that period, sends the decoded temperature onto said display of said alarm clock, and triggers said sound alarm of said alarm clock when the decoded temperature crosses a presettable alarm temperature threshold,whereby (c) and (d) synergetically share a significant number of common parts with (b), thereby lowering the overall expense of remotely monitoring the temperature data sent by (a).

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. The receiver shares many common parts and functions with the alarm clock or the computer, and therefore becomes inexpensive enough to be affordable by any household.

18. A device combining both a temperature telemetry receiver and an alarm clock that share the following elements;
-
an electrical circuitry keeping time and able to measure time intervals, a numeric display, both of the time of day and of telemetered temperature, shown either simultaneously or successively, a noise producing alarm selected from the group consisting of loudspeakers, vibrators, bells, and buzzers, a plurality of buttons or switches to set time and temperature alarms, and to stop said alarms, a back-up fail-safe battery to ensure that said alarms would be triggered should a primary source of electrical power fail, and that further comprises a telemetry radio receiver and associated signal and data processing circuitry to receive and decode temperature readings sent by a remotely situated telemetry transmitter, thereby providing a multipurpose and convenient means to monitor and periodically supervise the temperature of a child or adult patient, especially at night. - View Dependent Claims (19)
