    摘要: A low permeability hose system for providing an impermeable length of tube to transfer fluids that is flexible. The low permeability hose system generally includes a hose defining a fluid passage and an impermeable layer attached to the exterior surface of the hose. The impermeable layer is comprised of an aluminum coated heat sealable film that is impermeable to both liquids and gases. A protective layer may be attached to the impermeable layer to protect the impermeable layer from damage.

    摘要: A electro-desorption compression system according to the present invention comprises an enclosure which includes first and second spaced-apart electrical conductors, a sorbent which is positioned in the enclosure between the first and second conductors, a sorbate which is capable of combining with the sorbent in an adsorption reaction to form a sorbate/sorbent compound, a power supply which is connected to the first and second conductors and which generates an electrical current that is conducted through the sorbate/sorbent compound to desorb the sorbate from the sorbent in a desorption reaction, and a pressure chamber which is connected to the enclosure and which receives the sorbate from the enclosure during the desorption reaction and releases the sorbate into the enclosure during the adsorption reaction. The adsorption and desorption reactions are repeated to cycle the sorbate between a relatively low pressure state during the adsorption reaction and a relatively high pressure state during the desorption reaction. Furthermore, the desorption reaction is substantially non-thermal.

    摘要: An integrated digital light modulator. In one embodiment, a light beam is split into a set of binary weighted beams which are then individually switched on or off by an optical switch. The weighted beams which are conveyed by the optical switches are then recombined to produce a modulated beam. In this manner, a fast inexpensive integrated digital light modulator may be advantageously obtained. Broadly speaking, the present invention contemplates a digital optical power modulator that comprises a binary power divider and an optical modulator. The binary power divider is configured to receive an input light beam and split it into a set of weighted beams. The optical powers of the weighted beams are related in that the ratio of the optical powers of any two weighted beams is substantially an integer power of two. The optical modulator receives the set of weighted beams from the binary power divider and receives a digital signal. The optical modulator is configured to convey weighted beams that correspond to asserted bits in the digital signal. The present invention may further include an optical combiner coupled to receive the weighted beams from the optical modulator and configured to combine the weighted beams to produce a modulated beam having a discrete optical power. A lookup table may be included to convert a desired digital power value into the digital signal provided to the optical modulator.

    摘要: An array of termination resistors has symmetrical geometry producing essentially no net magnetic field and a resultant low inductance is fabricated on a substrate as disk resistors. Conductive through vias are formed in the substrate in an array pattern defining what will be resistor first and second contacts. Each disk resistor has one first contact located at the resistor disk center, and preferably four second contacts located symmetrically about the resistor disk and shared by four adjacent disk resistors. For each resistor, a annular-shaped disk of resistive material is fabricated on a first surface of the substrate, such that a central opening in the disk overlies at least the upper surface of a first contact via. The disk geometry and material determines its resistance. Next, a layer of conductive material is formed over the first surface of the substrate to cover at least the periphery of each disk, and to fill the central opening in each disk. This conductive material electrically couples at least the periphery of each resistive disk with each second contact via to define V.sub.T nodes, and also separately electrically couples the disk center to the underlying first contact via. Solder balls at the lower surface of each via provide an array of first and second contacts for each resistor for attaching the substrate to a printed wiring board or other substrate. An array may include hundreds of termination resistors having substantially real impedances in the range of 50 .OMEGA. to 100 .OMEGA. at frequencies up to about 12 GHz.

    摘要: A system configured to detect faults in signal lines. A system includes a first component configured to communicate with a second component via a signal path including one or more signal traces. Sense signal lines are manufactured such that at some point they are in close proximity to a signal trace which is to be monitored. The sense signal lines are configured to use parasitic coupling to redirect a portion of a signal conveyed via a signal trace to a monitoring component. The first component is configured to convey a test signal indicative of a type of test via the signal path, and a reference signal to the monitoring component. The monitoring component is configured to utilize the reference signal to ascertain a presence or absence, or characteristics of a received redirected signal. The monitoring component may optionally utilize a locally generated reference signal.
