A filter recognition system for use with an air purifier is provided. The air filter assembly or filter clip includes identification pins/taps which are read by the air purifier to determine the filter type. The filter recognition system adjusts the motor parameter based on the filter type. Additionally, the filter recognition system adjusts the filter timer to automatically communicate to a user the recommended time to change the filter based on the identified filter type.

Filter recongnition system

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.

A heating blanket reduces the possibility of electrical arcing by providing a series of individual heating elements each carrying a low current.

Heating blankets with low-current multiple heating elements

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.

Temperature compensation warming fabric

Heat losses from electric heating pads, blankets and pillows are reduced by aligning heat reflective strips or coatings over the top of a heating wire arranged inside the pads, blankets and pillows. By reducing heat losses, lower wattage can be applied to the heating wire to transfer the same amount of heat to a user as equivalent higher wattage blankets which do not have the heat reflective strips. By lowering the applied wattage, a more efficient blanket results.

The present invention provides an improved system and method for sensing the presence of ice, particularly applicable in the control of ice thickness in machines employing an ice bank such as a commercial beverage chiller. The chiller may be of the conventional type having a water bath with a cold element at least partially submerged therein. The cold element is cooled by a refrigerant such as freon to the point where ice forms and grows on the element, thereby forming an ice bank in the water bath. A temperature sensor, which preferably is a thermistor-type sensor comprising a bead disposed in a metal housing, is mounted on a carrier to allow the position of the sensor to be adjustable relative to the cold element. Circuitry is provided which is operative to detect the presence of ice by sensing a temperature signal from the temperature sensor and to control the thickness of the ice bank. A method of controlling the thickness of an ice bank is also disclosed. The invention has broad applicability to all types of machines wherein an ice bank is used.

Ice thickness control system and sensor probe

The present invention provides an improved system and method for sensing of ice, particularly applicable in the control of ice thickness in automatic ice-making machines. The ice-making machine may be of the conventional type using a cold plate with water flowing over it. A thermistor bead temperature sensor is encapsulated in a metal housing, which is in turn mounted on a carrier. The position of the carrier is adjustable relative to the cold plate. The control system has several variable delays or time durations which optimize system performance: 1. Minimum harvest time delay, relative to the start of the ice-making cycle; 2. Threshold persistence time delay, requires that the signal sensor persists above the harvest threshold value for a certain amount of time (referenced to when the threshold is first exceeded), before harvesting may begin; 3. Harvesting delay is an optional delay provided give the option of making sure the ice is sufficiently &ldquo;cured.&rdquo; These delay times may be implemented in hardware (by being built into the control logic), software, or by a combination of both hardware and software. The improved sensor and control concepts offer their own benefits and may be used separately or together.
