  • Patent number: 5440193
    Abstract: An apparatus, system and method for actuating or sensing strains in a substrate which includes at least one actuator/sensor element which has transverse and longitudinal axes. The actuator/sensor element is attached to the substrate in such a manner that the stiffness of the actuator/sensor element differs in the transverse and longitudinal axes. In this manner, it is possible to sense or actuate strains in the substrate in a desired direction, regardless of the passive stiffness properties of the substrate, actuator element or sensor element. An isotropic actuator/sensor element attached to a substrate in this manner can then operate in an anisotropic way. In a preferred embodiment, the actuator/sensor element is bonded to the substrate at an area of attachment occupying only the central third of the actuator/sensor element in its longitudinal axes. The actuator/sensor element may be a piezoelectric, magnetostrictive, thermally actuated lamina (including bi-metallic) or shape memory alloy element.

  • Patent number: 5365214
    Abstract: The musical wireless alerting system includes several detectors (12) which transmit rf signals to a common receiver (14). The detectors (12) include manual switches thereon to allow manual selection of a song or melody. The selection is coded in the form of an audio code which is transmitted to the receiver (14). The receiver (14) detects any rf transmissions and verifies that the received transmissions are identifiable with the receiver (14). Upon verification, the receiver reads the audio code and compares same to a plurality of stored songs or tones within memory for transmission to a speaker which plays the tone or song. Each of the detectors (14) may sense different predefined conditions and indicate different audible indications to be played. The detectors may sense conditions such as opening of the door or depression of a door bell.
