  • Patent number: 6693260
    Abstract: The present invention relates to furniture, such as cabinets, benches with storage, and armoires, that include at least one chamber that is configured to heat, cool, or alternate between heating and cooling. As such, any or each chamber may be dedicated to heating or keeping items warm; dedicated to cooling or keeping items cool; or configured to heat and cool as desired. Multiple chambers may be provided in any one piece of furniture that are capable of such heating and cooling in any combination. The furniture may also include chambers for traditional storage without heating or cooling capability. The invention is preferably used outdoors for keeping garments and towels warm for swimmers and bathers when configured for heating.

  • Patent number: 6570138
    Abstract: A warming chamber defining a heated internal cavity is presented having a door that may be opened or closed to provide access to the cavity for the storage of, for example, food products. The chamber includes a temperature sensor that sends signals to a control regarding the sensed temperature within the cavity. The control then activates heating elements when necessary to maintain the cavity at a predetermined temperature. The control further senses when the door has been opened, and supplies a power boost to the heating elements in anticipation of a cooling effect even though a temperature drop within the cavity has not yet been sensed.

  • Publication number: 20030089703
    Abstract: The present invention relates to systems and methods for enhancement of biometric object image capturing. These systems and methods prevent undesirable interruptions of total internal reflection of a prism that result in improper biometric images. In embodiments of the invention, a thermal assembly comprising a plurality of thermal elements is placed adjacent to the image capturing device. The thermal elements upon supply of a current are capable of either heating or cooling the image capturing device or a platen of the image capturing device. If cooling of the biometric object receiving surface is required, the thermal elements can be controlled to decrease temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed.

  • Patent number: 4689303
    Abstract: Described herein is a controlled circulation incubator device having a plurality of plate receiving trays held by a tray bracket. Heated air is circulated by a blower and heater assembly around the trays held by the tray bracket and the temperature of the flowing heated air is sensed by a thermister included in a temperature controller circuit. The termister is coupled in a circuit so that its resistance determines the amount of heating provided by the heater portion of the blower and heater assembly. Each of the trays have a front lid and a back lip and the plurality of trays are offset from one another within the confines of the incubator device. The angle of the back lip and the amount of offset are selected so that each of the back lips are positioned in a generally planar surface. This causes the front lip, which extend at a slight angle from the receiving trays, to extend into the circulating air stream and air is forced between adjacent trays to heat the contents held by the trays.

    Abstract: In a substantially transparent insulating structure, positionable between a warmer region and a colder region, the improvement comprising an infrared reflecting visible light transmitting coating, applied to a surface of a pane in the structure. The coating reflects a substantial portion of infrared radiation incident thereon, so as to restrict substantial transmission of infrared radiation from the warmer region to the colder region. The reflected infrared radiation heats the surface exposed in use to the warmer region sufficiently to inhibit formation of a visibility-impeding layer thereon, without using electrical energy therefor. The reflected infrared radiation is reradiated into the warmer region, thereby inhibiting reradiation of such reflected infrared radiation into the colder region. The coating further transmits a substantial portion of visible light radiation incident thereon, to enable substantially clear visibility therethrough.

  • Patent number: 4278870
    Abstract: A dental mirror warmer to prevent fogging when the mirror is placed in a patient's mouth includes a housing with a cover having an opening. Below the opening is a heating well to receive the reflective end of the mirror. The well has a stainless steel wall connected to a transformer which supplies high current at low voltage to heat the wall. The supply to the transformer is controlled by a photoresponsive device responsive to insertion of the mirror and a timing circuit which permits current supply for a short heating interval. A temperature sensor shortens the interval when heating cycles are initiated frequently. The photoresponsive device is mounted in the housing in juxtaposition with a light transmissive opening in a wall of the heating well. The photoresponsive device includes a source of light arranged to direct light into the heating well through the opening and a photoresponsive element arranged to receive light reflected from the reflective surface of a mirror inserted into the heating well.

  • Patent number: 4260876
    Abstract: A control circuit for proportionally controlling the application of available ac current to thin film heaters and other heating apparatus for transparent windows and other selected surfaces of refrigerated cabinets prevents condensation of moisture thereon. A transducing sensor in contact with the ambient air and thermally coupled to the refrigerated cabinet surfaces provides control signals to an ac heating current control circuit in relation to the difference between cabinet surface temperature and the dew point temperature of the ambient air. As the cabinet surface temperature drops closer to dew point the application of electric power to the transparent window and other surface heating apparatus is proportionally increased by the control circuit by applying heater current during correspondingly increased "on" periods for passage of the available ac heater current. "On" periods of the heater current are initiated during times in a cycle when the ac is at or near its null.

  • Patent number: 4248015
    Abstract: Apparatus is described for decreasing the frost-free recapture time of a multi-pane glazed door such as is used on refrigerated display cabinets, by selectively heating the innermost pane when it is exposed to high relative humidity conditions. An electric current is passed through an optically transparent electrically conductive layer on the unexposed surface of the innermost pane. This heats the pane to a temperature above the dew point of the ambient air.

  • Patent number: 4119834
    Abstract: A food warmer includes a plurality of trays and associated lamps mounted on a frame for rotation in unison about a stationary standard. Each lamp is arranged above each respective tray to project heat downwardly only into the tray with which it is associated. The trays are pivotally supported on the frame and a switch associated with each tray is closed by pivotal movement of the tray upon placement of food on the tray to energize the lamp associated with the tray. A rotary connector is disposed between standard and frame, so that current can be supplied to each lamp regardless of the rotary position thereof. Each tray is detachable from the frame for cleaning and a switch override is selectively disposed between the tray and housing to prevent closing of the switch and energization of the lamp when necessary.

  • Patent number: 4038518
    Abstract: A dining table which automatically maintains food at an optimum temperature all the while the food is on the table. Disposed beneath the table top, which permits flux linkage therethrough, is apparatus which generates one or more electromagnetic fields with each of the fields of influence thereof extending upwardly through the table top. Placing a peculiar food vessel within each field of influence causes an electromotive force (EMF) to be generated within conductor windings disposed therein. The food vessel also includes a heating element which is connected to the conductor windings; this heating element is powered by the EMF being generated by the conductor windings. Thus, a nominal amount of heat is developed which keeps the food contained within the food vessel at an optimum temperature.
