    Abstract: An electrical system responsive to overheating and/or electric arcing of an electrically conductive member, e.g. a heating member of an aircraft windshield, includes a first switch in a first current path, and a second switch in a second current path. The first current path is from an electrical power supply through the first switch, through an arc sensor to the heating member to the power supply. The second current path is from a temperature sensor monitoring the temperature of the heating member through the second switch to a temperature controller. When the temperature of the heating member is at or above a predetermined value, the temperature controller causes the first switch to open. When there is arcing, the second switch is moved to the open position. The temperature controller senses that the second switch is open and causes the first switch to open.

  • Patent number: 8378265
    Abstract: A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower is disclosed. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.

  • Patent number: 8247744
    Abstract: There is provided a cooking device that prevents an electricity conduction setting to a heating source from fluctuating when a user is not intending to operate a touch key. The cooking device includes a heating source for heating an object to be heated; a top plate provided on an upper surface of the device; a touch key that is provided on the top plate and is operable to input a control command by being touched with a finger; a cancel electrode provided at a periphery of the touch key; and a control unit for controlling an electricity conduction to the heating source based on the control command. When detecting that a portion of the top plate near the cancel electrode is touched with the finger, the control unit maintains a condition of electricity conduction to the heating source in time of the detection, and limits an operation based on the control command input to the touch key while detecting that the portion of the top plate near the cancel electrode is being touched with the finger.

  • Publication number: 20120205365
    Abstract: A cook top with at least two heating elements includes a power electronics arrangement connected to a domestic single phase AC supply. The power electronics arrangement includes several power supply units, which each supply heating currents to one or more heating elements, and a switch arrangement with several electromechanical relays for connecting/disconnecting the power supply units to/from the heating elements. Output poles of at least two electromechanical relays associated with different power supply units are connected in parallel, wherein the parallel connection is permanently connected to at least one of the heating elements. This arrangement reduces the number of switching processes required for alternating use of a power supply device with several heating elements, and simplifies compliance with electromagnetic compatibility standards.

  • Patent number: 8138455
    Abstract: A novel method for introducing delays in self timed memories is disclosed. In the proposed method, delays are introduced by introducing a capacitance on the path of signal to be delayed. The capacitances are realized by using idle lying metal layers in the circuit. The signal to be delayed is connected to these idle lying capacitances via programmable switches. The amount of delay introduced depends on the capacitance introduced in the path of signal which in turn depends on state of the switches. The state of the switches is controlled by delay codes provided externally to the delay introducing circuitry. Since, in the proposed method, idle-lying metal capacitances are utilized, the circuit can be implemented using minimum amount of additional hardware. Also delay provided by the proposed circuitry is a function of memory cell spice characteristics and core parasitic capacitances.
