Abstract: Circuit to clamp the voltages in the electrodes of the CHEF system chambers of Pulsed Field Gel Electrophoresis (PFGE) which is formed by two identical clamping circuits that are connected to a power supply through an alternator and only one of the two circuits receives electric power at the same time. Each clamping circuit is formed by several resistors and diodes connected in series to form a voltage divider. Voltage repeaters are connected to the nodes formed in the union of two resistors. Each repeater is connected to a pair of electrodes that should be polarized at the same potential. Diodes are introduced to correct small errors in the voltage pattern applied to the electrodes. The circuit is able to maintain the potential of each electrode in front of the variations of conductivity that occur inside the chamber during the electrophoresis. This way each imposition circuit generates a homogeneous electric field of same value and different direction in a PFGE chamber of the CHEF system.

Abstract: A broadband surface mounting package includes a housing having a flat bottom wall forming parallel first and second surfaces. An integral wall forms, with the bottom wall, an enclosure having a top opening to provide access to an interior compartment or cavity to receive a microwave component. The second surface is arranged to contact a printed circuit board (PCB) for attachment to lands or pads on the PCB. Cylindrical holes in the enclosure each defines an axis parallel to the bottom wall, and has a dimension, generally transverse to the bottom wall, to extend from the second surface to at least the first surface, and has an axial length sufficient to provide a through hole in the wall and a gap within the bottom wall proximate to and inwardly from the wall.

Abstract: The invention relates to laser materials and specifically to single crystal active media for solid state lasers operating in the middle-infrared (Mid-IR) 4-5 ?m range of optical spectrum, wherein a cross section of stimulated emission and laser wavelength is shifted to the range of atmospheric transparency with a single crystal orthorhombic structure with space group D242h-Fddd. The material contains Lead, Gallium, Sulfur and is doped with Dysprosium according to general formula: Pb1?3xDy2xGa2S4, where 0.0001<x<0.05. Lasers operating in this matter and in this spectral range are advantageous for lidar applications, free space communication, environmental monitoring, and other purposes.

Abstract: The Fitness Device comprises a back contacting member and a leg contacting member, with a pivotally mounted contacting member that is attached to said back contacting member. When driven by a motor or hand-operated power source, said pivotally mounted contacting member causes the position of said back contacting member relative to said leg contacting member to change, applying more or less pressure to the user's back (depending on the movement of said back contacting member) and thereby allowing the user's back to stretch relative to said leg contacting member.

Abstract: Proposed is a circuitry and a related control mechanism for a vehicle with electric drive only or for a vehicle with hybrid drive comprised of an electric and a combustion motor. This circuitry has a multi-phase machine and two direct current units. Furthermore, an arrangement of power semiconductor components, in two converters in bridge arrangement of two semiconductor switches whose respective alternating current connections are connected in phase direction and to the connections of the multi-phase machine. The negative polarity connections of the two direct current units and the two converters are also connected to each other, the positive polarity connection of the first direct current unit is connected to the positive connection of the first convert by means of a flow control valve and the positive polarity connection of the second direct current unit is connected to the positive connection of the second converter by means of a flow control valve.

Abstract: A system for the automatic collection of closed caption text wherein broadcast source of closed caption text are received by a tuner, then decoded and a text handler writes text files. A remote inquiry client is operably connected to the tuner and a server, to push the text files from the inquiry client to the server. A previously submitted search profile originated by the inquiry client is automatically compared with the text files and parsed to create a inquiry client search result, and the useful inquiry client is then automatically contacted regarding the search result.

Abstract: A rack-mounting system includes a rack with a number of shelves for mounting electronic modular components. At least two modular components are mounted on each shelf, each component with width approximately equal to W/n, where W equals the width of the shelf and n equals the maximum number of modular components to be mounted on a single shelf. Each modular component is fully self-contained, stand-alone, and operates with full independence of the other self-contained, stand-alone components. At least two modular components have the same function. Means is provided for switching out a defective component and switching in a standby component that performs the same function, thus enhancing redundancy.

Abstract: Restrictions on the frequency of a carrier signal are removed. This invention comprises a power section for receiving the carrier signal and creating an internal voltage, a clock-generating section for creating an internal clock based on a clock pulse that is carried by the carrier signal, a memory section, a writing section for storing data that is carried on an optical signal in the memory section, and an output section for reading the data in the memory and load-modulating the carrier signal.

Abstract: A liquid loading and application apparatus includes a hub, a paint roller support element, and the hub receives the paint roller support element. The hub includes first and second frusto-conical surfaces subtending an angle, and oppositely disposed annular end surfaces contiguous with the respective first and second frusto-conical surfaces. A cover of a first material conforms to the frusto-conical surfaces. The cover has opposed circular openings, and elastic strips of a second material. The elastic strips engage the frusto-conical surfaces and grippingly secure the cover to the hub. The first material is more elastic than the second material so that the strips grippingly secure the cover to the hub.
