Abstract: A location based holding system comprises a holding device. The holding device includes a food storage chamber and a temperature sensor. The temperature sensor senses the temperature of the food storage chamber. A temperature control device changes the temperature of the food storage chamber. A location device determines the physical location of the holding device. A memory stores information about a food item located in the food storage chamber. A processor is operatively coupled to the memory, location device, and holding device. The processor activates the temperature control device of the holding device based on the physical location of the food storage or transportation device.

Abstract: A pressure sensitive acoustic wave sensor and actuator include an acoustic wave cavity fo?ned in a substrate, a transducer generating an acoustic wave substantially trapped in the acoustic wave cavity and an acoustic wave absorbing member that absorbs more acoustic wave energy in the acoustic wave cavity in response to increased pressure on the member. The speed and/or braking of an electric vehicle is controlled through operator input of a foot pedal, using the pressure sensitive acoustic wave sensor.

Abstract: A switch assembly comprising a body, an actuator, and a base design to provide a device that can actuate various Hall-Effect chip devices in a single design. The switch assembly of the invention may provide a momentary switch connection, such as a single push system, or a maintained switch connection, such as a push-push system. Further, the switch assembly may include feedback mechanisms, such as LED components and the like that provide a visible feedback of the switch connection, and tactile feedback components that also indicate the switch connection.

Abstract: A switch assembly includes a unitary push button housing including an actuable button, a retainer having a first surface and a second surface, in which the retainer is secured within the push button housing, a snap dome secured on the first surface of the retainer, and at least one terminal passing through the second surface of the retainer to the first surface. The button is configured to be actuated into the snap dome, so that the snap dome is urged into contact with the terminal.
