摘要:
A federated marketplace provides a context-based environment for consumers to purchase products and services directly from an Internet-based search engine results page, without the need to navigate to the sponsoring merchant's Web site. Detailed descriptions of sponsoring merchants' products and services are presented directly within the search result Web page, for example, as a layer that may be activated by consumer indications of interest. Meta data identifying the sponsoring merchant's goods or services may be retrieved from the sponsoring merchant's Web site, either directly or by a search robot, and catalogued within the marketplace. A particular tagging schema may be used to provide Meta data identifying product data for retrieval. An immediate download of a product to a consumer may commence upon purchase.

Antennas are provided for electronic devices such as portable computers. An electronic device may have a housing in which an antenna is mounted. The housing may be formed of conductive materials. A dielectric antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A proximity sensor may be used in detecting external objects. A parasitic antenna resonating element may be interposed between the antenna resonating element and the dielectric antenna window to minimize near-field radiation hotspots. The parasitic antenna resonating element may be formed using a capacitor electrode for the proximity sensor. A ferrite layer may be interposed between the parasitic element and the antenna window.

摘要:
An acoustic imaging system coupled to an acoustic medium to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers formed at least in part from a thin-film piezoelectric material, such as PVDF. The array is coupled to the acoustic medium opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

According to one aspect a method for manufacturing a holographic storage medium includes providing one or more data masks with data to be recorded, illuminating the one or more data masks onto the medium with a plane wave object beam from a laser light source operating at a record wavelength, propagating a reference beam at an incident angle to the medium to record the one or more data masks on the medium, and altering the incident angle of the reference beam for each of the one or more data masks, wherein each of the one or more data masks recorded on said medium can be read bit by bit using a laser light source operating in a readout range of wavelengths different from the record wavelength.
摘要:
A spinal implant, e.g., to replace an excised disc, comprises a rigid generally horseshoe shape of biocompatible material, such as carbon-fibre reinforced plastics, having upper and lower planar faces (10, 11) converging towards the ends (12) of the horseshoe, and at least one hole (13, 14) from each planar face (10, 11) emerging in the outer curved face (15) of the horseshoe, to enable the horseshoe to be fixed by screws inserted through one or more selected holes in each plurality (13, 14) from the ends in the outer curved face (15) into respective adjacent vertebrae, with the screw heads bearing against shoulders (18), and with the space bounded by the inner curved face (17) of the horseshoe available for the insertion of bone graft or a bone graft substitute.

A stereophonic sound reproduction system comprises an amplifier (11) having two channels (A, B) connected by wires (17,18) to twin loudspeaker assemblies (12A, 12B). To enhance the sound a bypass (19) is connected across one only (A) of the two channels. The bypass (19) consists of a capacitor C.sub.1 of 1.1 Microfarads, a wire-wound resistor R of 2,200 ohms and an inductance (which may be formed at least partially by the inductance of the wire-wound resistance R) of about 2.2 Microhenries. When reproducing digitally-processed sound, the bypass is augmented by a capacitor C.sub.2 of 0.22 Microfarads in series with an inductance of 3 Microhenries.

An electronic device may have a housing in which an antenna is mounted. An antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A capacitive proximity sensor may be used in detecting external objects in the vicinity of the antenna. The proximity sensor may have conductive layers separated by a dielectric. A capacitance-to-digital converter may be coupled to the proximity sensor by inductors. The capacitive proximity sensor may be interposed between an antenna resonating element and the antenna window. The capacitive proximity sensor may serve as a parasitic antenna resonating element and may be coupled to the housing by a capacitor.
摘要:
Described is a technology by which private content maintained behind a firewall (e.g., in a “mesh”) may be searched, browsed, and accessed via an index that exists outside of the firewall. Searching of the index may include checking permissions of a user against permissions associated with metadata in the index, e.g., per watch folder into which file content is added. When content is selected, e.g., by clicking on a search result, a request is made. An application polls for such requests, and when detected, pushes a copy of the content through the firewall to the requester. The search may be performed over more than one index, with aggregated search results returned.
