Abstract: A system and method for testing telescope optics are disclosed. The telescope optics can be testing in-situ, thus more accurately revealing the as-used optical conditions. The optical conditions are input to a test system which, by objective analysis, reveals a condition of the optics and an indication of the need for corrective action. A test bench for testing optics and for validating the test system using modeled telescope optics is also disclosed.

Abstract: An image projecting apparatus includes a light source, a relay lens, a reflective light valve, and a projection lens. The light source is capable of emitting a light beam. The relay lens is disposed to permit the light beam provided by the light source to pass therethrough, and has a lens periphery formed with a notch. The reflective light valve is spaced apart from the relay lens, and is disposed to receive and modulate the light beam passing through the relay lens into an image light beam. The projection lens is disposed proximate to the notch of the relay lens, and is capable of projecting the image light from the reflective light valve to display an image onto a screen. The relay lens has a plurality of light-absorbing regions proximate to the notch for reducing a light-splitting effect attributed to the notch.

Abstract: We describe an ultra-small structure and a method of producing the same. The structures produce visible light of varying frequency, from a single metallic layer. In one example, a row of metallic posts are etched or plated on a substrate according to a particular geometry. When a charged particle beam passed close by the row of posts, the posts and cavities between them cooperate to resonate and produce radiation in the visible spectrum (or even higher). A plurality of such rows of different geometries are formed by either etching or plating from a single metal layer such that the charged particle beam will yield different visible light frequencies (i.e., different colors) using different ones of the rows.

Abstract: A holding device for rod-shaped components comprising holding elements that move through a series of positions. To hold a component the holding elements move in sequence from open releasing positions, to contacting positions, to aligning positions and finally to fully closed positions. Holding elements in aligning positions permit the held component to be moved and aligned even though the holding elements are more firmly in contact with the component than in their contacting positions. Slide-resistant surfaces formed on the holding elements are made in such a way that in the case of the movement of a misaligned component, sliding resistance is intensified in one direction while sliding resistance is reduced in another direction to permit movement of the component in that direction into the desired alignment. The holding elements are moved in the opposite sequence to release a component.

Abstract: A torque anchor for use with progressive cavity pumps (PC Pumps) for preventing rotation of the PC Pumps and any related tool string within a well bore, possessing a connector constructed and adapted to connect a tube, which in a preferred embodiment is a diluent cable, between the two fixed slips. A method is also recited for running coiled tubing or a diluent cable downhole using the torque anchor.

Abstract: In an optical switch, a set of coherent electromagnetic radiation is selectively delayed and recombined to produce constructively or destructively combined radiation. When the radiation is constructively combined, a signal is transmitted out of the switch to a remote receiver. When the radiation is destructively combined, a signal is not transmitted out of the switch to a remote receiver.

Abstract: A remote access device is disclosed for capturing, digitizing and communicating video signals from a host computer to a remote computer. The remote computer returns keyboard and mouse signals through the remote access device to the host computer to control the host computer as though the remote keyboard and mouse were directly connected to the host computer. The remote access device includes a circuit module interface for the host computer that allows the remote access device to operate independently of any operating system characteristics associated with the host computer.

Abstract: For ensuring that a vending machine motor will continue to operate until a product has descended through a vending space or an established time interval has elapsed, an optical beam is established across the vend space through which a product must drop. A change in beam intensity is detected. By preference infra red light is emitted at one focal point of an elliptical reflector, and detected at the other focal point. The light is emitted in pulses in the preferred embodiment, and the optical sensing system has automated calibration and error detecting functions.

Abstract: A device and method is provided that includes a window for coupling a signal between cavities of a device or between cavities of different devices. A wall or microstructure is formed on a surface and defines a cavity. The window is formed in the wall and comprises at least a portion of the wall and is electrically conductive. The cavity can be sized to resonate at various frequencies within the terahertz portion of the electromagnetic spectrum and generate an electromagnetic wave to carry the signal. The window allows surface currents to flow without disruption on the inside surface of the cavity.

Abstract: A video compression system is disclosed that is optimized to take advantage of the types of redundancies typically occurring on computer screens and the types of video loss acceptable to real time interactive computer users. It automatically adapts to a wide variety of changing network bandwidth conditions and can accommodate any video resolution and an unlimited number of colors. The disclosed video compression encoder can be implemented with either hardware or software and it compresses the source video into a series of data packets that are a fixed length of 8 bits or more. Sequences of one or more of these packets create unique encoding “commands” that can be sent over any network and easily decoded (decompressed) with either software or hardware. The commands include 3 dimensional copying (horizontal, vertical and time) and unique efficiencies for screen segments that are comprised of only two colors (such as text).

Abstract: A down hole flow control device used in a well bore includes a central mandrel and a packer ring disposed thereon. The packer ring is compressible along a longitudinal axis of the central mandrel to form a seal between the central mandrel and the well bore. Upper and lower slip rings are disposed on the central mandrel and include a plurality of slip segments joined together by fracture regions to form the slip rings. The fracture regions are configured to facilitate longitudinal fractures to break the slip rings into the plurality of slip segments that secure the down hole flow control device in the well bore. The upper and lower slip rings have different fracture regions from one another to induce sequential fracturing with respect to the upper and lower slip rings when an axial load is applied to both the upper slip ring and the lower slip ring.

Abstract: The present invention is directed toward methods and systems for monitoring resource usage in an architecture where neither the resource buyer nor the resource seller can be trusted, and for rewarding benefits, compensation, or rewards based upon such monitored resource usage data. The system rewards users who offer to share the memory, storage, or bandwidth of their computing resource to third parties within a distributed network. In an exemplary embodiment, users share processing, storage, bandwidth or memory resources with third parties by permitting such third parties to access files stored in the memory of the users' computing devices. Users that offer files for upload are encouraged to register with a central authority, and receive value each time a third party accesses a resource from their computing devices. The value awarded to each such user is tracked by the central authority. They can use the value in exchange for products or services.
