  • Patent number: 11064833
    Abstract: Food stuffs are cooked at precise temperatures, which are optionally below 100° C., in a vessel that is evacuated to exclude air, in which low pressure steam replaces the air. When a sufficient quantity of air is excluded and replaced with water vapor, the temperature of vapor is accurately measured inside the vessel below the lid to control the temperatures within about 1° C. Air is preferably excluded via a controlled heated process for a relatively short period of time at high temperature to generate steam, the temperature is lowered to condense water vapor upon which the lid will sealingly engage the rim of the vessel, forming a partial vacuum in the cooking vessel.

    Abstract: In a solid-state heating system, once a load with specific load characteristics has been placed in a heating cavity, a processing unit produces control signals that indicate an excitation signal frequency and one or more phase shifts, which constitute a combination of parameter values. Multiple microwave generation modules produce RF excitation signals characterized by the frequency and the phase shift(s). Multiple microwave energy radiators radiate, into the heating cavity, electromagnetic energy corresponding to RF excitation signals received from the microwave generation modules. Power detection circuitry takes reflected RF power measurements, and the processing unit determines a reflected power indication based on the measurements. The process is repeated for different combinations of the parameter values, and an acceptable combination of parameter values is determined and stored in a memory of the heating system.

The system provides speech recognition for powering on and off, dimming, brightening, and adjusting the lighting; including presets and emergency situations. The voice recognition command controls lighting choices, and can silence or suspend alarm-state by verbally commanding SHUT OFF. The base station monitors and programs individual LED and detecting devices that create a network within a home or structure to manage lighting and security.

  • Patent number: 9909780
    Abstract: The present invention is a system for tank recovery comprising a tankless having an outlet and a storage tank that is operatively connected to the tankless. A pump is operatively connected to the tankless and the pump is operatively connected to the storage tank. A first thermistor is in thermal communication with the outlet of the tankless. The first thermistor measures a first temperature of the outlet of the tankless when the pump is active. A second thermistor is in thermal communication with the storage tank. The second thermistor measures a second temperature of the storage tank. A controller has a stored default temperature for the tankless. The controller receives the measured second temperature from the second thermistor. The controller compares the stored default temperature for the tankless to the measured second temperature from the second thermistor.

  • Patent number: 9837219
    Abstract: A contact wetting circuit 100 is disclosed for supplying wetting current to sense the state of dry contacts of a switch SW1 setting for an electronic device 10. The contact wetting circuit includes an RC circuit 110 having a resistor R1 and a capacitor C1, and a controller 120 connected to a power supply 130 of the device. The controller supplies a first voltage to the RC circuit to produce a charging current having an average current and/or a peak current below the wetting current parameter of the dry contacts. The charging current is used to charge the capacitor C1 during the first time period. The controller stops the supply of the first voltage to the RC circuit after sufficient charging to allow the charged capacitor C1 to supply a second voltage, across the switch SW1, to produce a wetting current. Thereafter, the controller polls and senses the state of the switch SW1, and performs certain operations accordingly.

  • Patent number: 9816478
    Abstract: A method for regulating or controlling the temperature of a sheathed-element glow plug in a heating phase of the sheathed-element glow plug, where a temperature value is determined as a function of a resistance of the sheathed-element glow plug. To render possible the regulation or control of the temperature of the sheathed-element glow plug also during a transient temperature distribution within the sheathed-element glow plug, the resistance used for determining the temperature value during a transient thermal response within the sheathed-element glow plug is calculated with the aid of a physical model.

  • Patent number: 9806595
    Abstract: A method for controlling an electrical converter comprises the acts of determining an error value based on a difference between an estimated output value and a reference output value, the estimated output value being based on measurements in the electrical converter; comparing the error value with an error band and in the case of the error value exceeds the error band, controlling the electrical converter by switching to a different control scheme. The converter is controlled with the modified pre-calculated switching by determining a pre-calculated switching sequence for the converter based on an actual state of the electrical converter, the switching sequence comprising a sequence of switching transitions of the converter; modifying the pre-calculated switching sequence by modifying transition times of switching transitions of the pre-calculated switching sequence, such that the error value is minimized; and applying at least a part of the modified switching sequence to the electrical converter.

    Abstract: There is provided a method of controlling an electrical heating element, including maintaining a temperature of the heating element at a target temperature by supplying pulses of electrical current to the heating element; monitoring a duty cycle of the pulses of electrical current; and determining if the duty cycle differs from an expected duty cycle or range of duty cycles, and if so, reducing the target temperature, or stopping the supply of current to the heating element or limiting the duty cycle of the pulses of electrical current supplied to the heating element. As the temperature is maintained at a known target temperature, any variation in the duty cycle or range of duty cycles expected to maintain the target temperature is indicative of abnormal conditions.
