Abstract: Systems and devices for providing differential input/output communication with a superconducting device are described. Each differential I/O communication is electrically filtered using a respective tubular filter structure incorporating superconducting lumped element devices and high frequency dissipation by metal powder epoxy. A plurality of such tubular filter structures is arranged in a cryogenic, multi-tiered assembly further including structural/thermalization supports and a device sample holder assembly for securing a device sample, for example a superconducting quantum processor. The ace between the cryogenic tubular assembly and room temperature electronics is achieved using hermetically sealed vacuum feed-through structures designed to receive flexible printed circuit board cable.

Abstract: A method of spectrum restoring and broadening to produce high resolution seismic data from a plurality of shot records in a seismic survey is described. The method includes the steps of: dividing each shot record into a plurality of windows, in which each of the relevant variables is practically constant, and wherein each window contains one or more trace segments; forward modelling of spectral signatures for any ghost reflections in the shot records using a best estimate of all known parameters, such that every trace segment will have an observed and a (prior) modelled spectral signature; calculating an inverse operator to correct the spectral notches in every trace segment using a constrained set of final fitted values for all the relevant variables; and, recombining the processed trace segments to produce a final set of shot records whereby, in use, the deleterious effects of the ghost reflections in the shot records can be substantially eliminated.

Abstract: Magnetic shields and magnetic shielding systems are described. The excessive spatial demands of known mu-metal/cryoperm and superconducting shielding systems are reduced by a new multi-piece shield construction approach. A complete magnetic shielding system for use with superconducting-based computing systems, such as superconducting quantum computing systems, is also described. This complete system may include mu-metal/cryoperm shields and superconducting shields using either compensatory magnetic fields, expulsion by temperature gradients, or a combination of the two.

Abstract: An ergonomic work station (10) includes a base (12) with a standing surface (14) adapted to support a person in a standing position. A first support member (16) extends upwardly from the base (12). An anatomical support (18) is mounted to the first support member (16). A second support (20) member extends outwardly from the first support member (16). The second support member (20) has an attachment end (22) and a remote end (24). A third support member (26) extends upwardly from the remote end (24) of the second support member (20). At least one office equipment support (28) is mounted to the third support member (26). The office equipment support (28) is height adjustable, thereby enabling a person to work from either a first position resting upon the anatomical support (18) or a second working position standing upon the standing surface (14) of the base (12).

Abstract: A back pressure regulating device can be incorporated either into a fuel cell test station or into a fuel cell power module. For each of fuel can oxidant lines, it provides a gas pressure regulator. The pressure regulator is controlled by a pilot gas, supplied, preferably, through a pressure regulating valve and a three-way valve. Another port of the three-way valve provides a vent through a check valve and a needle or other flow control valve. The needle valve is connected to both check valves for the pilot gas lines for the fuel and oxidant. In normal operation, the pilot gas pressure, regulated by the pressure regulating valve, is supplied to the appropriate pressure regulator to control the respective fuel and oxidant gas pressures. On shut down or in case of power failure or the like, the three-way valve defaults to a condition in which it connects the pressure regulator through the respective check valve to the needle valve.

Abstract: A fuel cell fluid distribution layer, in one embodiment, comprises perforated graphite foil. The fluid distribution layer can have one or more reactant flow field channels formed in one or both major surfaces, one or more manifold openings, conductive filler on one or both major surfaces, conductive filler at least partially filling some or all perforations and/or an electrocatalyst one or both major surfaces.

Abstract: A system for treating process fluids delivered to an electrochemical cell stack is described. The system includes a treatment unit capable of treating and imparting a first range of temperatures to a process fluid that includes the freezing point of water. A filter removes ice particles larger than a particular size formed when the first temperature unit imparts a temperature to the process fluid low enough to cause ice particles to form.

Abstract: An electrochemical cell cooling system includes a closed loop for circulating coolant through an electrochemical cell. The loop includes a pump for pumping the coolant from a container through a filter and a heat exchanger. Pressure in the container and loop is selectively adjusted upwardly for a positive pressure condition or downwardly for a negative pressure condition using a pressure-adjusting flow line. The flow line includes a venturi in fluid communication with the container and a shut-off valve downstream of the venturi which is opened to induce depressurization of the loop or closed to cause pressurization. A variable-flow valve upstream of the venturi enables fine adjustment of the pressurization or depressurization. Alternatively, a flow-restricted bypass and a second variable-flow valve can be introduced to facilitate coolant temperature control.
