  • Patent number: 8607921
    Abstract: A hearing protection process comprises (a) providing at least one hearing protection device comprising at least one sound barrier comprising at least one substantially periodic array of structures disposed in a first medium having a first density, the structures being made of a second medium having a second density different from the first density, wherein one of the first and second media is a viscoelastic medium having a speed of propagation of longitudinal sound wave and a speed of propagation of transverse sound wave, the speed of propagation of longitudinal sound wave being at least about 30 times the speed of propagation of transverse sound wave, and wherein the other of the first and second media is a viscoelastic or elastic medium; and (b) interposing the hearing protection device between an acoustic source and an acoustic receiver in the form of a human ear.

  • Publication number: 20080034301
    Abstract: A method for constructing a graphical representation of a plurality of tables in a restaurant is carried out by a computer system. A receiver coupled to the computer system is in communication with a plurality of transmitters, each transmitter being responsive to a stimulus that causes the transmitter to transmit a unique message frame to the receiver. The computer system responds to a received message frame by checking to determine if the unique message frame had already been received during the current construction process, and if the message frame had not been received, displaying an icon representing a table associated with the transmitter. Each transmitter is subjected to the stimulus, thereby causing each transmitter to send the message frame to the receiver, and thereby causing the computer system to display one icon for each table.
