Abstract:
A core-shell catalyst includes a porous, palladium-based core particle and a catalytic layer on the particle. The particle can be made by providing a precursor particle that has palladium interspersed with a sacrificial material. At least a portion of the sacrificial material is then removed such that the remaining precursor particle is porous.
Abstract:
A lighting apparatus and method of use provides for increasing the visibility of a cyclist. The lighting apparatus includes a plurality of lights that may be arranged in a linear array to facilitate attachment to elongate members of a bicycle. The plurality of lights can be mounted on a substrate that is received in a mounting member, which in turn can be attached to a bicycle. Alternatively, the lighting apparatus may be formed integrally as part of a bicycle. Attachment of one or more lighting apparatuses to a bicycle can provide for increased visibility of a cyclist from the front, the rear, or the side, and may be configured to provide increased visibility when it is either dark or light outside.
Abstract:
An item-providing system supplies items to a user device for consumption at the user device via communication infrastructure. In one illustrative implementation, the communication infrastructure may rely, in part, on wireless communication. The device may correspond to a book reader device or other type of device.
Abstract:
The present application describes various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes internal components configured to fit within a relatively thin outer enclosure.
Abstract:
There is disclosed methods and apparatus for decomposing a signal having a plurality of channels into direct and diffuse components. The correlation coefficient between each pair of signals from the plurality of signals may be estimated. A linear system of equations relating the estimated correlation coefficients and direct energy fractions of each of the plurality of channels may be constructed. The linear system may be solved to estimate the direct energy fractions. A direct component output signal and a diffuse component output signal may be generated based in part on the direct energy fractions.
Abstract:
A table and chair set may include a table, a plurality of chairs and a storage case. The table may include a folding table top that has a footprint in the folded position. The chairs may be folding chairs that have a footprint generally equal to or slightly smaller than the footprint of the table in the folded position. The case may include an interior cavity that is sized and configured to receive at least a portion of the table and the chair in the folded positions, the cavity having a size generally equal to or slightly larger than the footprint of the folding table and the folding chair in the folded positions.
Abstract:
The disclosed process comprises freeze-drying a biodegradable implant device comprised or one or more polyesters to thereby reduce moisture content in the device.

Abstract:
Text content embedded with multimedia content is provided from a content provider to a client device. The multimedia content may be provided to the client device separate from the text content. In particular, multimedia content metadata indicating a storage location of the multimedia content may be provided to the client device after the text content. The client device may request the multimedia content from the content provider based on the multimedia content metadata. The content provider may send the requested multimedia content to the client device after receiving an authenticated version of the multimedia content metadata.
Abstract:
A system for providing decoder-specific content is provided. The system includes a receiver list system receiving a receiver identifier and transmitting authentication data to a receiver. A receiver authentication system receives the authentication data and transmits content delivery data to a content server, such as data that authorizes the content server to provide content to the receiver. A receiver update system transmits update data to the receiver, such as a list of available channels of content.
