  • Publication number: 20070051241
    Abstract: A hydrogen supply system (FIG. 1) comprises a first hydrogen storage material (1), which may be an AB5 type material, and a second hydrogen storage material (2) which may be a MgH2 type material; wherein the two hydrogen stores are separate. The first hydrogen storage material can be activated to release hydrogen at a lower temperature than can the second hydrogen storage material and at least a proportion of the hydrogen released from the first hydrogen storage material is utilised to activate the second hydrogen storage material. Hydrogen released from the second hydrogen storage material is made available to a hydrogen consumption system (3). The system is particularly suited for use as a mobile hydrogen supply, for example to provide hydrogen to a fuel cell powered vehicle.

  • Publication number: 20060266803
    Abstract: Electrical oscillations are supplied to electrodes of a diathermal heating chamber. A liquid is passed through the diathermal heating chamber so as to be heated. The liquid has a minimum level of dissolved solids, which is replenished over time or when the dissolved solids in the liquid fall below a predetermined minimum level. Alternatively, when the level of dissolved solids is excessive, current input or liquid temperature is reduced.

  • Patent number: 7077007
    Abstract: A process for forming a microelectromechanical system (MEMS) device by a deep reactive ion etching (DRIE) process during which a substrate overlying a cavity is etched to form trenches that breach the cavity to delineate suspended structures. A first general feature of the process is to define suspended structures with a DRIE process, such that the dimensions desired for the suspended structures are obtained. A second general feature is the proper location of specialized features, such as stiction bumps, vulnerable to erosion caused by the DRIE process. Yet another general feature is to control the environment surrounding suspended structures delineated by DRIE in order to obtain their desired dimensions. A significant problem identified and solved by the invention is the propensity for the DRIE process to etch certain suspended features at different rates.

  • Publication number: 20060075010
    Abstract: A method and apparatus, especially suited for computers that can execute fused multiply-add instructions, for performing a fast Fourier transform (FFT) are disclosed. Divisions by zero that create a risk of error in other methods are avoided. In a first example embodiment, a zero divisor is detected and the division circumvented by performing an alternate computation. In a second example embodiment, a zero divisor is detected replaced by a safe finite value. In a third example embodiment, two optimized FFT kernels are used, one avoiding division by a zero real part of a root of unity and one avoiding division by a zero imaginary part. In a fourth example embodiment, a first kernel computes some kernel iterations without multiplication, and a second, optimized kernel computes the remaining iterations without risk of division by zero.

  • Publication number: 20050233078
    Abstract: A method for forming a film of material using chemical vapor deposition. The method includes providing a substrate comprising a pattern of at least one metallic nanostructure, which is made of a selected material. The method includes determining a plasmon resonant frequency of the selected material of the nanostructure and exciting a portion of the selected material using an electromagnetic source having a predetermined frequency at the plasmon resonant frequency to cause an increase in thermal energy of the selected material. The method includes applying one or more chemical precursors overlying the substrate including the selected material excited at the plasmon resonant frequency and causing selective deposition of a film overlying at least the portion of the selected material.

  • Publication number: 20050202185
    Abstract: The present disclosure methods and systems that provide heat, via at least Photon-Electron resonance, also known as excitation, of at least a particle utilized, at least in part, to initiate and/or drive at least one catalytic chemical reaction. In some implementations, the particles are structures or metallic structures, such as nanostructures. The one or more metallic structures are heat at least as a result of interaction of incident electromagnetic radiation, having particular frequencies and/or frequency ranges, with delocalized surface electrons of the one or more particles. This provides a control of catalytic chemical reactions, via spatial and temporal control of generated heat, on the scale of nanometers as well as a method by which catalytic chemical reaction temperatures are provided.

  • Patent number: 6848226
    Abstract: An access panel for providing access to cables, services or the like through an opening in a floor having a floor covering, is disclosed. The access panel includes a floor frame (10) located in the opening and a lid (100) supported on the frame (10). The frame (10) has a support flange (26) extending around its periphery which extends between the floor covering and the floor deck. The flange (26) provides a ramped edge tapered substantially uniformly over a distance of between 10 and 20 times the maximum thickness of the flange (26). The outermost part of the flange (26) is typically formed from a flexible polymeric material. A rib (20) extends around an aperture in the frame (10) and the height of the rib (20) is lower than the load bearing surface of the floor. The hinge (24, 120) is generally square and defines a pivot surface which extends parallel to and is spaced inwardly from an inner edge of the frame (10).

  • Patent number: 6749199
    Abstract: A dice-less Craps game is disclosed. The game may be played by dealing, by a dealer, a pair of cards having numerical indicia thereon; determining whether the pair of cards are of a like suit; if the cards are not of a like suit, then adding the numerical indicia together to determine a roll in accordance with the rules of Craps; and if the pair of cards are of a like suit, then arriving at a predetermined result other than a roll in accordance with the rules of Craps. In a further disclosed aspect, the first predetermined result comprises a NoCall. In a further disclosed aspect an apparatus for playing a dice-less Craps game is disclosed, comprising a deck of cards comprising 48 cards having numerical indicia thereon including four like-suited pairs each of Aces, Twos, Threes, Fours, Fives, and Sixes; and a Craps playing surface having additional indicia thereon for wagering on a predetermined result if a pair of dealt cards are of a like suit.

  • Publication number: 20040024286
    Abstract: An actuation system for assisting the operation of the natural heart comprises a framework for interfacing with a natural heart, through the wall of the heart, which includes an internal framework element configured to be positioned within the interior volume of a heart and an external framework element configured to be positioned proximate an exterior surface of the heart. The internal framework is flexibly suspended with respect to the external frame. An actuator system is coupled to the framework and configured to engage an exterior surface of the heart. The actuator system comprises an actuator band extending along a portion of a heart wall exterior surface. The actuator band is selectively movable between an actuated state and a relaxed state and is operable, when in the actuated state, to assume a predetermined shape and thereby indent a portion of the heart wall to effect a reduction in the volume of the heart.
