    Abstract: A sound attenuation panel that includes an incident wall and a frame unit connected to the incident wall. The incident wall defines an aperture therethrough. The frame unit includes multiple spoke members spaced apart from one another and radially extending from one or more central hub openings of the frame unit. The one or more central hub openings align with the aperture of the incident wall. The frame unit defines channels between adjacent pairs of the spoke members. The channels fluidly connect to the one or more central hub openings. The frame unit is configured to receive sound waves into the central hub opening through the aperture of the incident wall to dissipate the sound waves through the channels between the spoke members.

  • Publication number: 20200342088
    Abstract: A system for providing authentication data for user devices. System includes a database storing first data, for each device, indicative of a first instance of the device characterization derived from static orientations of the respective devices. A system interface receives from a device, second data that is indicative of a second instance of the device characterization. An authentication module is responsive to the first and second data to selectively generate authentication data. A user device includes a device interface for: receiving a request to provide the second instance of the characterization; and transmitting a response. The user device also includes a reference module that provides a measurable output including a bias and a processor that is responsive to the request for: prompting module for the measurable output; producing the instance of the characterization based at least in part upon the measurable output; and generating the response containing second data.

  • Patent number: 8066831
    Abstract: A method of generating power uses a nanoenergetic material. The nanoenergetic material comprising thermite is obtained and deposited on a substrate. An igniter is placed on the nanoenergetic material. When power is desired, the nanoenergetic material is ignited. A transducer receives thermal, sonic, magnetic, optic and/or mechanical energy from combustion of the nanoenergetic material and converts it into electrical energy. Preferably, the transducer is a thermoelectric, piezoelectric or magneto device. Preferably, multiple transducers are integrated in one power generators to maximize the power from nanoenergetic thermites.

  • Publication number: 20080209353
    Abstract: There is described a graphical user interface in a computer system. The GUI comprises a window containing a plurality of user interface controls. The proposed GUI also includes means for grouping a set of user interface controls, from amongst said plurality of user interface controls, into a single control pane in response to a first user input. The GUI further comprises means for displaying said control pane within said window. The means for displaying is adapted to display said control pane in any one of an expanded configuration and a folded configuration, depending upon a second user input. The expanded configuration displays said control pane with user interface controls that are contained in the control pane, while the folded configuration displays the control pane in a minimized form along with a control pane identifier.
