Abstract: A content hosting system allows content providers to create channels of video content and make them available to users in a marketplace. Users can search or browse for channels of interest, and selectively subscribe to channels. Users can also pay for the right to view premium videos in each channel. The system ranks channels according to the value provided. Generally, users will seek out and subscribe to the highest ranked channels that provide the greatest value. The ranking function allows different providers to compete for the subscriptions of users. Providers can observe their channel's reception in the market by analyzing rankings and usage statistics to adjust channels to maximize channel performance. The system operator can also create bundled channels containing videos from multiple providers, and the resulting subscription revenue can be distributed to the various providers of the videos in the channel.

Abstract: A sanitizing system for water treatment in appliances that use or that have an associated water cycle where sanitization of the water in the water cycle is beneficial. The system comprises a controller, a biocide, and a biocide injection subsystem, wherein the controller provides a signal to the injection subsystem to release a biocide into a water reservoir contained within the appliance, and further wherein the signal provided by the controller is in response to a signal received by the controller from the appliance.

Abstract: A sanitizing device used to sanitize a bulb syringe. The device preferably includes a base, a bulb receiver, and a sanitization system. The sanitization system produces a sanitizing gas that is propelled into and possibly around a bulb syringe in order to sanitize the surfaces of the syringe. The sanitization system preferably includes an ionization module, a fan, electrodes, and a power supply. Preferably, the sanitization system is housed in a conical housing which includes a central nozzle and an array of openings centered around the nozzle exit. The sanitization device preferably includes an automatic switch that is activated by the presence of a bulb syringe or upon placing a cover over the device.

Abstract: The present invention includes drill pipe screens and related methods that provide reliable long-term filtering of drilling fluids used to operate alternator turbines that are used to provide power in measurement while drilling (MWD) systems without allowing debris to pass through the screens to the turbines, and without causing intermittent pressure spikes at times when the screens are not completely clogged while maintaining desired circulation rates of drilling fluids. Embodiments of the invention include cylindrical bodies having alternating sets of elongated slots and peripheral ports located thereon to provide filtering of and relief to drilling fluids under pressure.

Abstract: An electronic textbook system allows instructors to create custom coursebooks by integrating various materials from disparate sources. Instructors can arrange the materials, format them, provide tables of contents and indices. Payment mechanisms as well as policies for the components are integrated automatically so that the final book satisfies policy requirements for each of its component parts.

Abstract: An electronic book system provides interfaces particularly suited to students' use of textbooks. Annotations are displayed and hidden using specific gestures and through selective movement of the reader as sensed by its accelerometer. Motion of the electronic book reader below a threshold speed causes a change in display of user-selected content in a first manner and motion above the threshold speed causes a change of display in a second manner.

Abstract: A method of producing a non-planar conforming circuit on a non-planar surface includes creating a first set of conforming layers. The first set of conforming layers is created by applying an oxide dielectric layer to the surface, applying a conductive material layer to the oxide dielectric layer, applying a resist layer to the conductive material layer, patterning the resist layer according to a desired circuit layout, etching the surface to remove exposed conductive material, and stripping the resist layer. The process may be repeated to form multiple layers of conforming circuits with electrical connections between layers formed by blind microvias. The resulting set of conforming layers can be sealed.

Abstract: A valve actuation system is described containing a collapsible pushrod device for use in a reciprocating piston machine cylinder such as an engine. The collapsible pushrod device replaces a conventional pushrod. The system can include a driver base, plunger, and a deactivation pin assembly. In normal operation, the pins lock the driver base and plunger together thereby providing regular valve motion. Under selected conditions, the pin assembly controller unlocks the driver base from the plunger. Valve lift is reduced or eliminated. When eliminated, the cylinder is deactivated. The system can vary the effective compression ratio between higher for cold starting and other selected operating conditions and lower for warmed-up running, as well as trap additional exhaust residuals to assist starting and light load. This is especially useful for Diesel engines. Various means may be used to unlock the pins including oil pressure, bi-metal spring temperature, or electromagnetic activation.
