Abstract: Purchase history data is used to determine items that were purchased by a first user account. The user selects a subset of the items for inclusion in a user interface and provides access to the user interface to other user accounts. Characteristics of the items are determined, based on the purchase history data or based on item data from seller devices, and are included in the user interface. Images of items in the user interface may be provided with a background color that is complementary to the color of the depicted item to provide the user interface with a uniform appearance. The user interface may include links that enable users to initiate a purchase or navigate to a website associated with an item or seller. The first user account may be notified if another user account purchases an item using the user interface or after viewing the user interface.

Abstract: Plasma cathodes for micro Hall and ion thrusters of unprecedented power efficiency, low cost, compactness, are provided. The cathodes employ, for example, a very small planar scandate cathode as electron source, delivering over 350 ma of discharge from an emitter area as small as only 0.012 cm2.

Abstract: Wireless systems and methods establish an optimal wireless communication link by efficiently positioning an antenna module to receive/transmit the most effective signal. An antenna module scans and rotates and receives data such as available networks and the qualities of received signals. Received networks are analyzed, recorded and mapped to antenna variables such as azimuth, elevation and polarity. Automatic or manual selection of a wireless network is based upon antenna variables, qualities of received network signals and predefined conditions. If desired, a more refined antenna position is obtained by the addition of spiral antenna rotations and additional recordings of received data are mapped to antenna elevation, azimuth and polarity. In the event the measured effective signal reception diminishes, the center destination of the spiral path shifts and the process repeats until the highest effective signal reception is found.

Abstract: The disclosed technique, apparatuses and devices enable a mobile device to act as a pointing device equipped with integrated search tools, to define a virtual beam within which to search and discover information associated therewith. The user of the mobile device does not have to type, speak or otherwise specify keywords as search criteria. The search criteria can be merely the virtual beam itself. Search results are generated at a remote server system and communicated back to the mobile device, and then presented to its user via graphical, audio and/or other format.

Abstract: An exit window for an electron beam emitter through which electrons pass in an electron beam includes a structural foil for metal to metal bonding with the electron beam emitter. The structural foil has a central opening formed therethrough. A window layer of high thermal conductivity extends over the central opening of the structural foil and provides a high thermal conductivity region through which the electrons can pass.

Abstract: A therapeutic method in which plural points on the body are stimulated by light of different wavelengths emitted from wands, probes or other applicators under the control of a central microprocessor. The microprocessor executes program instructions to produce light at each applicator whose intensity, frequency, duration and pulsation accord with protocols which are automatically selected depending on the portion of the body being treated. The protocols can be manually overridden by the therapist, in which case the changed parameters are stored in memory. The apparatus is particularly useful in performing traditional therapeutic methods to treat internal disorders, substance abuse, pediatric and podiatric problems and disorders of the ear, nose, throat, as well as musculoskeletal, neurological or dermatological disorders.

Abstract: An exit window can include an exit window foil, and a support grid contacting and supporting the exit window foil. The support grid can have first and second grids, each having respective first and second grid portions that are positioned in an alignment and thermally isolated from each other. The first and second grid portions can each have a series of apertures that are aligned for allowing the passage of a beam therethrough to reach and pass through the exit window foil. The second grid portion can contact the exit window foil. The first grid portion can mask the second grid portion and the exit window foil from heat caused by the beam striking the first grid portion.

Abstract: An electron beam emitter including a vacuum chamber having a width. An electron generator can be positioned within the vacuum chamber for generating electrons. An elongate nozzle can extend from the vacuum chamber along a longitudinal axis and have an exit window at a distal end of the nozzle. The nozzle can have a width that is less than the width of the vacuum chamber. The electron generator can be shaped and dimensioned, and positioned with the vacuum chamber to form and direct a narrow electron beam that enters and travels through the nozzle, and exits out the exit window.

Abstract: A gas separation apparatus includes an irradiation chamber for receiving a gas. An irradiation device irradiates the gas within the irradiation chamber for causing molecules of the gas to break apart into larger and smaller constituent components. A separation arrangement separates the larger and smaller constituent components from each other within the irradiation chamber by forcing the larger and smaller constituent components toward different regions of the irradiation chamber. An outlet removes the smaller constituent components from the irradiation chamber.
