Title: Apparatus and method for inserting and retrieving a tool string through well surface equipment
Inventor: MULLER LAURENT E
IPC: E21B33/068
Filed: 2002-06-06
Abstract: Well surface equipment is provided to seal around the outer surface of portions of tool sections as the tool sections are assembled or disconnected in a portion of the well surface equipment. The portion of the well surface equipment is isolated from wellhead pressure to enhance well operator control during assembly or disassembly of a tool string.  Also, if a fluid path is opened up due to activation of the tool string (such as initiation of a detonating cord that is placed in the fluid path), a barrier mechanism is actuated to block fluid communication through this fluid path so that a portion of the well surface equipment can remain isolated from wellhead pressure to enable convenient retrieval and disconnection of tool sections.

Abstract: Described is a vibration stimulus delivery device for delivering a vibration stimulus to an animal and for maximizing the robustness and intensity of the vibration stimulus. The vibration stimulus delivery device is carried by the animal and includes a housing and a vibration probe. The vibration probe is positioned in direct contact with the skin of the animal and generates a vibration, which, when delivered to the animal, is the vibration stimulus. The vibration probe is coupled to the housing such that the coupling minimizes the inherent vibration dampening effect caused by the weight and mass of the housing. The result is a vibration stimulus delivery device that delivers a more robust and intense vibration stimulus to the animal.

Abstract: Polarization preserving front projection screens and diffusers provide optimum polarization preservation for stereo-scopic 3D viewing, as well as improved light control for enhanced brightness, uniformity, and contrast for both 2D  and 3D systems.  Generally, the disclosed screens direct light from a projector toward viewers within a diffusion locus, while maintaining optimum gain characteristics. More specifically, light incident on a region of the front projection screen from a predetermined projection di-rection is reflected by an engineered surface to a predetermined diffusion locus after undergoing substantially single reflections. The engineered surface, comprised of generating kernels, is used to optimally diffuse illumination light into a range of viewing angles, within the diffusion locus, with suitable gain profile, while optimally preserving polarization for 3D applications. Such a screen, when combined with matched polarization analyzing eyewear, provides extremely low cross-talk from any observation point.

Title: Device, system and method for directly generating alternating current electricity from photovoltaic cells
Inventor: OLIVER JASON ALLEN
IPC: H01L25/00
Filed: 2009-09-24
Abstract: A device, system and method for generating alternating current (a/c) electricity directly from photovoltaic cells utilize an array of photovoltaic cell pairs that are each connected in anti-parallel to form an a/c junction. The system, device and method mechanically gradually exposes and shades photovoltaic cell pairs to sunlight to generate alternating current electricity at an a/c junction of the solar cell pairs.  Gradually and alternately exposing and shading the two anti-parallel connected solar cells of each solar cell pair causes the amplitude and polarity of the electricity at the a/c junction to gradually rise and fall to produce alternating current electricity. The gradual, alternating exposure and shading of the two anti-parallel solar cells is accomplished by mechanically covering and exposing the solar cell pairs. This is efficiently accomplished by a rotating segmented disc positioned over an array of solar cell pairs.
