Abstract:
An improved noise making device (10) particularly suited for use in stadiums, arenas and the like comprises a flexible, planar member of "whooping plate" (12), and a handle (14), both preferably comprised of plastic, the ends of the handle (14) being joined to the ends of the planar member (12) with the central section of the handle bowed outwardly from the planar member, such that when the handle is gripped and thrust forward and backward, the planar member bows inwardly and outwardly, thereby generating a loud noise. Suitable indicia, such as a team logo or advertising message, may be imprinted on the outer surface of the planar member.
Abstract:
An acupressure pillow includes pressure members that are interconnected by an elastic member and arranged so that, when the user rests a body part (e.g., head or neck) on the pillow between the pressure members, the pressure members automatically adjust to accommodate the body part and produce pressure on the body part due at least in part to the elastic member, which biases the pressure members toward one another. Thus, the pressure exerted on the body part may have different vector components, including some pressure produced essentially perpendicular to the pillow surface on which the body part rests and some pressure produced at other angles due to the shape of the pressure members and the inward force on the pressure members produced by the elastic member.
Abstract:
The present invention provides for a method and apparatus for reducing interference associated with wireless communication in an area having sensitive electronic equipment. A wireless communications device receives, from an access point, a signal having a signal strength above a predetermined threshold. The wireless communications device determines a transmission power level maximum based on the received signal and then transmits a signal to the access point at a transmission power level at or below the transmission power level maximum. The wireless communications device disables the transmission when the signal strength falls below the predetermined threshold.

Abstract:
An intruder alarm includes a circuit with a photoresistive cell located in a housing with a piezoelectric crystal sound generator and battery to power the circuit and sound generator. A telescope concentrates light from a distance in a limited field of view upon the photoresistive cell to trigger the piezoelectric crystal sound generator when light intensity on the cell changes sufficiently from an ambient light intensity level.
