Responsive To Weight, Position, Or Presence Of Body To Be Heated Patents (Class 219/518)
  • Patent number: 10470604
    Abstract: A beverage forming method and system in which a heater tank can be filled with liquid to an expansion level after a beverage is formed. The liquid in the heater tank may be heated, causing expansion of the liquid in the tank. Thereafter, a volume of liquid may be delivered to the tank to fill the tank to a liquid delivery level at which the tank is filled to deliver a controlled volume of liquid to form a beverage. No further heating of liquid in the tank may be performed or required after filling to the delivery level since the volume of liquid delivered to fill the tank to the liquid delivery level may be relatively small. Accurate volumes of liquid may be delivered in a way that compensates for any expansion that may occur due to heating.

  • Patent number: 8669492
    Abstract: A passenger seat device includes a seat heater embedded in a seat and a detector electrode embedded underneath the seat heater. Electric power is supplied to the seat heater from an on-board battery through seat heater switches. Alternating voltage or current is supplied to the detector electrode. The detector electrode potential relative to the ground is lowered when the seat is occupied by a passenger. The changes in the potential of the detector electrode is detected by an occupant detector including a microcomputer. The detection is performed when the seat heater is brought to a floating state to suppress an amount of capacitance formed between the seat heater and the detector electrode. Thus, a sensitivity of the occupant detector is improved. The detector electrode may be eliminated, and the occupant conditions may be detected based on a potential of the seat heater to which alternating current or voltage is supplied.

    Abstract: A protective handle sheath including a body adapted to wrap about the existing appliance handle, a heat-activated anti-bacterial agent impregnated within the body, and first and second hook and loop strips attached to oppositely situated first and second longitudinal edges of the body respectively. The first and second hook and loop strips generate heat when engaged with each other such that the heat is transferred through the body and thereby transforms the anti-bacterial agent from an inactive state to an active state. In this manner, the anti-bacterial agent is released out from an interior of the body and thereby adapted to directly contact an outer surface of the existing appliance handle. Conversely, the anti-bacterial agent automatically returns to an inactive state when the first hook and loop strip is separated from the second hook and loop strip. Thus, the inactive anti-bacterial agent is absorbed into the interior of the body.

  • Patent number: 7361867
    Abstract: A scale having an electronic weighing system to generate a weight-dependent signal and a digital signal processing unit (18). The digital signal processing unit (18) has a circuit or program parts which measure the time elapsed since connection of the voltage to the scale. To dramatically reduce the time required for the scale to reach its full accuracy after connection of the voltage supply, the digital signal processing unit (18) has computation modules (34, 35) that correct the weight-dependent signal generated by the weighing system by a correction value that depends on the time elapsed. The magnitude of this correction value, starting from an initial correction value, converges with increasing time elapsed to a constant end value that differs from the initial correction value.

  • Patent number: 7157674
    Abstract: A detector is operable to detect a displacement of a load by an ascending force based on a period of time from a time a heating output of an inverter drops from a predetermined level to a first level, to a time the heating output returns back to a second level larger than first level. Thereby, the detector distinguishes an intentional removal of the load from the displacement of the load by the ascending force. An induction heater including the detector reduces the displacement of the load by the ascending force and stops the heating of the load when the load is removed intentionally.

  • Patent number: 7075044
    Abstract: An induction-heating cooking apparatus, operation of which is interrupted by container eccentricity is disclosed. Upon receiving an input signal varying with the degree of eccentricity of a container, the apparatus changes a reference signal for determining the presence or absence of a small load in proportion to a pulse-width control signal controlling the width of an inverter driving pulse. Although the eccentricity of the container occurs in a normal heating operation and completely escapes from a cook zone, the apparatus determines the occurrence of a no-load state, and interrupts an operation of an inverter circuit, resulting in increased stability of a circuit and a product.
