Abstract: A lamp, including: a plate, material thereof being optically transparent, the plate including two parallel surfaces and at least one rough width surface for illuminating outside the lamp; a plurality of illuminating sources disposed adjacent and along at least another width surface of the plate; and a user-movable shutter, for covering any of the plurality of illuminating sources, thereby the at least one rough width surface is uniformly illuminated, and thereby moving of the shutter adjusts intensity of the uniform illumination.

Abstract: A pan, including: a first cogwheel, being annular for surrounding the container of the pan, and for being rotational in relation to the container; a motor, for rotating the first cogwheel; and a stirring element extending from the first cogwheel into the container, thereby the stirring element stirs the contents of the container.

Abstract: A time-set accessory, including: a knob, being shaped complementary to a lever of a gas stove, for allowing manual rotation of the lever, for selecting a dispensing extent of the gas stove; an anchor, for anchoring the body of the time-set accessory to the body of the gas stove, thereby rotation of the knob about the time-set accessory's body, rotates the lever about the gas stove's body; and a timer, for manually setting a time, and for further automatically rotating the knob about the time-set accessory's body upon termination of the time, thereby rotating the lever about the gas stove's body.

Abstract: A lamp, including: a plate, material thereof being optically transparent, the plate including two parallel surfaces and at least one rough width surface for illuminating outside the lamp; a plurality of illuminating sources disposed adjacent and along at least another width surface of the plate; and a user-movable shutter, for covering any of the plurality of illuminating sources, thereby the at least one rough width surface is uniformly illuminated, and thereby moving of the shutter adjusts intensity of the uniform illumination.

Abstract: A circular lamp, including: a plurality of light sources disposed around a circle; a round cogged rotatable cover, disposed above each of the light sources for allowing covering thereof, wherein the round rotatable cover includes at least one aperture, for allowing exposing the light source; interlacing means, for allowing rotating at least one of the round cogged rotatable covers, for circularly moving the at least one aperture thereof, thereby allowing determining the number of the plurality of light sources to be covered.

Abstract: New sensors and methods for qualitative and quantitative analysis of multiple gaseous substances simultaneously with both high selectivity and high sensitivity are provided. The new sensors rely on a characteristic difference in energy between the interaction of a particular substance with a catalyst coated heat transfer device (HTD) and a non-catalyst coated (or one coated with a different catalyst) reference HTD. Molecular detection is achieved by an exothermic or endothermic chemical or physical reaction between the catalytic surface of the sensor and the molecule, tending to induce a temperature change of the sensor. Both high temperature and non-destructive low temperature detection are possible. The magnitude and rate of endothermic or exothermic heat transfer from a specific molecule-catalyst interaction is related to molecular concentration.

Abstract: A sense-simile sampler delivers a sample fragrance in response to receiving an external signal, preferably via the internet. The sampler has a fragrance reservoir attached to a cylinder via a tube. A piston plunger reciprocates in the cylinder to expel the fragrance. A one-way valve controls flow of fragrance from the reservoir into the cylinder. The piston plunger is solenoid operated via signals from an internet appliance.
