Electrical medical equipment that includes a user operable primary adjustment mechanism containing two or fewer user-adjustable elements, and a controller adapted to control and alter at least one output parameter of the equipment, the controller connected and responding to input from said primary adjustment mechanism to alter said output parameter, the primary adjustment mechanism having at least four conditions; a first condition which the mechanism returns to without user input, a second condition, following manipulation of one of the elements from a first condition, a third condition, following manipulation of one of the elements from a first condition, and a fourth condition following manipulation of the same element manipulated to achieve the third condition to another position, wherein in each condition, the mechanism provides a distinct output as input to the controller, which responds to the input by: maintaining the output parameter at a previous level while the input indicates the mechanism is in the first condition, incrementing or gradually increasing the prevailing level of the output parameter while the input indicates the mechanism is in the second condition, decrementing or gradually decreasing the prevailing level of the output parameter while the input indicates the mechanism is in the third condition, and setting the level of the output parameter to zero when the input indicates the mechanism is in the fourth condition.

Adjustment mechanism for electrical medical appliances, and methods of use

A radiant energy sensor is adapted to detect radiant heat energy incident on a surface. The energy sensor has a body portion with a pair of sides. A temperature sensor is located on each side of the body portion. In use the body portion is mounted on the surface such that one of the sensors is located between the body portion and the surface, thereby being masked by the body portion from heat energy otherwise incident on the surface.

Energy sensor

A system for heating a patient using a radiant heater is disclosed. In order to ensure optimum positioning of the patient various location and indication embodiments are included. The present invention either adjusts the energization of the heater to provide optimum heating, provides an indicator of the optimum position for the patient, indicates that the patient is not correctly positioned or any combination thereof.
