  • Publication number: 20090328171
    Abstract: Secure remote storage of electronic media. A virtual safe application resides on a server and provides for encrypted storage, display, and access to critical electronic media. The virtual safe communicates with trusted entities, which can automatically populate the virtual safe with pre-selected types of files into pre-selected locations. A user can access the virtual safe over a network to customize the display, manage files, upload files, and/or share files. Sharing a file grants selected access rights to a selected file by another authorized user. The shared file is displayed on the interface associated with the other authorized user, allowing the other user to view the file and to perform functionality consistent with the access rights. The sharing capability facilitates communication for use in streamlining business and/or personal matters. The virtual safe thus provides access to documents anytime, anywhere, while ensuring security, facilitating communication, and eliminating manual steps.

  • Patent number: 6559207
    Abstract: A flame resistant composition comprises (a) a polymer; (b) a synergistic mixture comprising(i) from about 0.6 to about 3 percent of a non-halogenated flame retardant compound; and (ii) at least about 0.06 percent of a compatible additive; wherein said percentages are based on weight percent of (a) plus (b), wherein (a) plus (b) equals 100 percent. A method of rendering a polymer flame resistant comprises compounding said polymer with a synergistic mixture comprising (i) from about 0.6 to about 3 percent of a non-halogenated flame retardant compound; and (ii) at least about 0.06 percent of a compatible additive; wherein the percentages are based on weight percent of polymer plus the synergistic mixture, and wherein polymer plus synergistic mixture equals 100 percent.

  • Patent number: 6550362
    Abstract: An apparatus (25) for transporting pre-measured quantities of fibers in a plurality of containers (13), separated by a plurality of webs (14), joining the containers together at spaced intervals, to a mixer (22) for cementitious materials, the apparatus comprising a conveying assembly (26), the containers therethrough; a counter assembly (28); a web slitting assembly (29); and a process controller (30), which activates the web slitting assembly in response to input from the counter assembly, in order to sever a determined number of the containers from the webs for conveyance into the mixer. A method for conveying pre-measured quantities of fibers suitable for the reinforcement of cementitious materials to a mixing apparatus is also provided as well as a train for providing pre-measured quantities of fiber comprising a plurality of containers containing the fibers; and a plurality of webs, joining the containers together at spaced intervals.

  • Patent number: 6122312
    Abstract: An apparatus for accurately transmitting and receiving acoustic waves indoors is provided. The apparatus contains a microphone, a speaker, a processing circuit, a first amplifier, a second amplifier, and a power control circuit. The microphone converts an input acoustic wave into an electric signal, and the speaker generates an output acoustic wave based on input data. The processing circuit processes the electric signal to produce processed data and outputs the input data to drive the speaker. The first amplifier receives a power signal and detects if a starting signal is contained in the electric signal output from the speaker. Then, the amplifier outputs a first detection signal when the starting signal is detected and outputs the power signal when the first detection signal is output. The second amplifier receives the power signal from the first amplifier and detects if a non-starting signal is contained in the electric signal when the starting signal is detected.

  • Patent number: 6011819
    Abstract: An acoustic communication apparatus includes a microphone/speaker for converting a power voltage and an aerial acoustic wave into an electric signal, and generating an acoustic wave corresponding to the input of data; a signal processing circuit for signal processing the electric signal output from the microphone/speaker in response to the input of the power voltage, the signal being received as data, the circuit outputting data responding thereto to thereby drive the microphone/speaker; a starting signal selection amplifier for always receiving the power voltage during a reception waiting mode, and detecting a starting signal having a predetermined frequency from the electric signal output from the speaker; a non-starting signal selection amplifier for receiving the power voltage in response to the detection of the starting signal, and selectively amplifying only a band excluding the frequency band of the starting signal; and a power voltage supply control circuit for supplying the power voltage to the signa
