A system controller such as a microprocessor receives voltage signals produced from a resistor identifying the functional or nonfunctional operating state of a power switch which controls the amount of power provided to a load in an electrical system. The resistor is also used to provide voltage signals representing the temperature of a heating element of the type used in heating pads and heating blankets. The functional or nonfunctional operating state of a safety switch in a safety circuit capable of blowing a fuse and cutting power to the load is periodically tested to ensure the safety of the electrical system.

Safety circuits for electric heating element

The response of a switch supplying electrical power to a load is periodically tested to ensure proper operation and control over the switch. In the event the switch does not respond to commands from a controller during a test cycle to turn off and open a circuit supplying power to the load, a short circuit is created by a test switch. In this event, a fuse is automatically blown preventing uncontrolled power from reaching the load. In one example, the load can take the form of a resistive heating element in an electric heating blanket or electric heating pad.

A compact portable path illuminating light can be coupled to mobility assisting devices such as walking sticks, canes and wheelchairs. A night beacon can automatically illuminate at timed intervals to assist a user in locating the light in the dark. This night beacon can be selectively enabled and disabled by a user. The status of various operating modes of the light are visually confirmed through illumination of several different colored lights.

A circuit integrity detection system for use in detecting the integrity of sensing wire in a heating pad wherein the integrity of the sensing wire is checking the inputs from a first and second A/D converter connected to opposite ends of the sensing wire.

Circuit integrity detection system for detecting the integrity of a sensing wire in electrically heated textiles

A circuit integrity detection system for use in detecting the integrity of a sensing wire in a heating pad wherein the integrity of the sensing wire is checking the inputs from a first and second A/D converter connected to opposite ends of the sensing wire.

The present disclosure is directed to a safety circuit for use in textile heating devices, such as heating pads, heating blankets, and the like. The safety circuit provides a system for checking/verifying the integrity of the controller, which can shut off power to the textile heating device if the controller has lost integrity.

Disclosed is a bath scale for measuring a user's weight having a weight display and a message display driven by a detection-and-display system adapted to provide through the message display one or more substantially non-deductive messages to the user of the bath scale that instruct the user in plain language how to use the scale.

Heating pad controller

A humidifier has a first sealable reservoir feeding water to a second reservoir communicating with ambient atmosphere. A blower is adapted to blow a stream of air through the humidifier to ambient atmosphere, such that the stream of air picks up water vapor from any water that may be in the second reservoir. A feeder valve feeds a quickly-evaporable quantity of water from the first reservoir into the second reservoir. The quickly-evaporable quantity of water in the second reservoir is substantially smaller than the water capacity of the first reservoir. A dry-out mechanism shuts off the feeder valve upon a user command and continues to run the blower at least until the quickly-evaporable quantity of water has evaporated to an extent effective in inhibiting the growth of microorganisms in the microorganism-vulnerable reservoir.

Microorganism-resistant humidifier

One or more current sensors are mounted externally of a heating member so as to simplify construction of the heating member. The sensors are particularly useful in safety control circuits for heating members using PTC wire as resistance heating elements.

Warming blanket having remote safety circuit

Disclosed is a warming blanket system having a fabric comprising a heating element, a data temperature mechanism configured to provide ambient air temperature data, a user input configured to provide user heat output preference data for a given normal ambient temperature, and a control system configured to input said air temperature and user heat output preference data and adjust heat output to said heating element based upon a deviation of a measured ambient temperature from said normal ambient temperature.

A humidifier having a lighted water tank. A lamp illuminates the tank so that the water level of the tank is visible from across the room. The lamp may extend into a lens, which in one embodiment is faceted to aid in dispersing light into the tank. The illuminated tank may also serve as a night light.
