  • Patent number: 7297888
    Abstract: A food slicer has a housing with a first push-button for actuating an electric switch for operating the cutting blade and a second push-button, i.e., a safety button, locking the first push-button against actuation. The second push-button actuates a mechanical lock which can be engaged and disengaged, blocking the first push-button in an inserted position of the lock, thereby preventing actuation of the electric switch that triggers an electric motor drive used to actuate a circular cutting blade. The first push-button is formed with a stop surface for the lock on which the lock is arranged, when it is in an inserted position, either at or in close vicinity of an axis extending through the center of the push-button surface, pointing in the direction of actuation, and on which the lock engages in an inserted position.

  • Patent number: 7277004
    Abstract: A system and method for a bi-directional deflectable resistor. The bi-directional deflectable resistor has a first layer of conductive material on a top surface of a substrate and a second layer of conductive material on a bottom surface of a substrate, each layer having a resistance that changes predictably when an electrical signal is applied thereto. The change of resistance of either the first layer of conductive material or the second layer of conductive material reflects an amount of deflection of the respective layer. Having two layers of conductive material allows for the measurement of deflection in all directions.

  • Patent number: 7268662
    Abstract: A hydrogen detecting system is characterized by a passive surface acoustic wave (SAW) sensor. The sensor includes a piezoelectric substrate having a self assembled monolayer arranged on at least a portion of the substrate to create a hydrophobic surface. A palladium nanocluster thin film is deposited on the monolayer and an interdigital SAW transducer is disposed upon the piezoelectric substrate for conversion of an RF signal into an acoustic wave and vice versa. At least one additional SAW element is also disposed on the substrate and spaced from the SAW transducer. The SAW element receives a signal from the SAW transducer and produces a response signal. The response signal is modified by the palladium nanocluster film due to a change in conductivity of the palladium nanocluster film upon exposure to hydrogen. This change in the response signal is measured by an interrogator, and yields a measure of the hydrogen concentration to which the sensor was exposed.

  • Patent number: 7265308
    Abstract: There is disclosed a paddle switch operated by pushing on the lower portion of a rocker paddle to turn the switch “on” or “off”. The lower edge of the paddle pivots in and out about its upper edge. The switch includes semi-rigid spiral wound driver means having a conical end coupled to be driven by the rocker paddle. When the rocker paddle is pushed in, the paddle urges the semi-rigid driver means to rotate a cam means in a first, clock wise direction, or a second, counter clock wise direction. Alternate rotation of the cam drives a slider member having a cam follower back and forth along a linear axis. A shaped leaf spring cooperates with the cam follower to assist in the movement of the slider and determines its rest positions. An indicator such as an LED is used to indicate the state of conduction of the switch. When the rocker paddle is released, it is biased by a spring to pivot back to its initial position.
