The system also includes a controller for selectively associating the interface device with any one or both of the first cooktop heating element and the second cooktop heating element. In another aspect, the system includes at least one cooktop heating element, a potentiometer, and controller arrangement operatively connected between the potentiometer and the at least one cooktop heating element to determine heating of the at least one cooktop heating element responsive to the input provided by the potentiometer and control power provision to the at least one cooktop heating element responsive to the determination.

Abstract: A disappearing interface system for a device, such as an appliance (e.g., a cooking range) having an interactive user interface, a light-emitting device (e.g., a LED), a microprocessor based LED fader electronic control system that uses a PWM signal to drive an A/D circuit to control the intensity (e.g., fade in/out) of the light-emitting device.

Abstract: A cooking device for cooking an item where the device includes an input for a source of cooking energy; a cooking element for applying the cooking energy to the item; a cooking control for controlling the application of the cooking energy to the item; a lockout selectable for preventing application of the cooking energy to the cooking element, the lockout being non-selectable when the cooking control is activated; and a user interface, the interface providing an indication of selection of the lockout in response to a user attempt to activate the cooking control when the lockout is selected.

Abstract: A cooking device includes a main oven, a controller for controlling the main oven, a mini-oven, and a control for controlling the mini-oven, wherein the control is in communication with the controller.

Abstract: An oven having a cooking cavity and a removable rack structure has a rack sensor in the oven. The sensor provides an indication of an absence or presence of the structure and an oven control permits oven cleaning in response to the indication of the absence of the structure or prevents oven cleaning in response to the indication of the presence of the structure.

Abstract: Compositions and methods are provided for ameliorating various effects of UVA and UVB radiation, especially from the sun. The compositions include an ingredient that prevents photoaging from MED and subMED radiation, namely an MMP (matrix metalloproteinase) inhibitor, especially formulated for oral administration, and more especially formulated for controlled-release so as to provide the MMP inhibitor when MMP induction (including upstream signalling molecules like c-JUN, and/or MMPs like stromelysin) is most prevalent.

Abstract: A range for heating foods having a body comprising a top surface, a first chamber located within the range, a second chamber located within the range, multiple heating elements arranged on the top surface for cooking food, an upper and lower heating element arranged within the first chamber, a warming element arranged within the second chamber, a control system further having a central processor for controlling the operation of the range, and an operator interface operatively connected to the central processor.

Abstract: Methods of treatment of cyanide-containing waste are provided. In particular, methods for treatment of spent potliner prior to landfill disposal are provided. These methods, which involve treatment of the waste with a mixture containing an aqueous oxidizing solution containing an agent, such as a metal chloride, that increases the oxidation potential of the solution, can be performed at ambient temperature and pressure.

Abstract: An asymmetric object, such as a lighter and ashtray, a clock and a base, a model airplane, etc has a base and the object levitates from the base. The base defines an interior space housing a base magnet. A support plate extends perpendicular to the base. The base also defines an interior space housing at least one base magnet. The base magnet is a permanent magnet having a north pole and a south pole. The lighter has an interior space, a base end, a levitating end, and a midpoint. The lighter has a conventional mechanism to create a flame. The lighter has at least one lighter magnet connected thereto. Lighter magnet is a permanent magnet having a north pole and a south pole and the lighter is selectively levitated from the base. Another group of levitated objects are selected from the group comprised of a toothbrush, hairbrush, comb, razor, lipstick, ruler, calculator, calendar, photograph frame, notepad and flashlight.

Abstract: An exemplary embodiment of the present invention is a method for dynamically managing a hash pool data structure. A request to insert a new key value into a hash pool data structure that includes at least one index level is received. An insertion location is calculated for the new key value in response to the new key value and to existing key values in the hash pool data structure. The insertion location includes an index level. A new index level is added at the insertion location if the index level is not the maximum number of index levels in the hash pool data structure; if the insertion location contains a chain of existing key values with a length equal to the maximum chain length; and if the new index record locations of the new key value and the existing key values are dispersed. The insertion location is updated in response to adding a new index record and the new key value is inserted into the insertion location.

Abstract: A lighter includes a housing a housing that forms a fuel reservoir. The housing has a fuel outlet extending from the housing. A valve assembly controls the flow of fuel exiting from the fuel outlet. A flint is mounted on the exterior of the housing for lighting fuel released from the fuel reservoir. A flint actuator includes a spark disk to engage the flint and a driver disk fixedly connected to the spark disk. A third disk is disposed between the driver disk and the spark disk and is freely rotatable therebetween. The third disk has a diameter greater than the driver disk. A plate is disposed between the driver disk and the housing and has a radially outwardly protruding portion between the housing and the driver disk, which is aligned with the driver disk and extends radially outwardly a greater distance than the driver disk from a central axis of the housing.

Abstract: A two-stage safety arrangement for a cigarette lighter of the piezoelectric type having a case that houses a flammable liquid container, gas release mechanism, and piezoelectric ignition element. The safety arrangement includes an ignition cover that covers the gas release mechanism, a striking lever, and a release button. To operate the lighter, a user must first depress the release button and use an upward movement to release the ignition cover and reveal the gas release mechanism. Next, the user must simultaneously depress the release button and push the striking lever rotatably downwards and away from the gas release mechanism in order to actuate the piezoelectric ignition element. Use of both hands to depress the release button and pry back the striking lever from above, near the gas release mechanism, is further prevented by providing a raised safety ridge to prevent a user from gripping the edge of the striking lever near the outlet of the gas release mechanism.
