Abstract:
An arrangement for passing an electrical signal between first and second areas includes a body disposable between the first and second areas and having an aperture. A first sleeve is at least partially disposed in the aperture and defines a first opening. A second sleeve is also at least partially disposed in the aperture and defines a second opening. The arrangement further includes an electrically conductive element having a first portion disposed in the first opening, and a second portion disposed in the second opening.
Abstract:
A regulator for regulating outlet pressure of a fluid supplied to the regulator from a fluid source includes a body having an inlet, and a pressure regulating chamber disposed in the body. A high pressure fluid circuit extends between the inlet and the pressure regulating chamber for transmitting the fluid from the inlet to the pressure regulating chamber. The high pressure fluid circuit includes at least two longitudinally extending high pressure passages in fluid communication with each other. One longitudinally extending high pressure passage transmits the fluid in a first direction, and another longitudinally extending high pressure passage transmits the fluid in a second direction different than the first direction.

A conductor array (100), for addressing a plurality of field emitters (130), including a plurality of cathode conductors (106, 108, 110) having conductive cathode connectors (126), a plurality of gate conductors (104) having a plurality of conductive gate connectors (116, 118, 120), and a plurality of fusible links (134, 138), which are located at a plurality of overlapping regions (103) of the cathode conductors (106, 108, 110) and the gate conductors (104) and which can be electrically severed to isolate electrical shorts existing at the overlapping regions (103).
Abstract:
A field emission device (10) has a gate (17) including an opening (22) for the communication of electrons from an emitter (14) to an anode (16). A resistive layer (18) is disposed at least on the inner surface (23) of the gate (17) surrounding the opening (22). The field emission device (10) may further include an insulating, dielectric layer (19). The resistive layer (18) and the dielectric layer (19) reduce arcing between the emitter (14) and the gate (17) in the field emission device (10).
Abstract:
A filter arrangement for use with a vessel containing pressurized fluid includes a body engageable with the vessel. The arrangement further includes a coalescing filter assembly supported by the body such that the filter assembly is disposable inside the vessel when the body is engaged with the vessel. In one embodiment of the filter arrangement, the coalescing filter assembly includes a housing having a cavity, a coalescing filter disposed in the cavity for removing entrained liquid from the fluid, and a drain device in fluid communication with the cavity for draining the liquid removed by the coalescing filter from the cavity into the vessel.
Abstract:
A display (10) utilizes a drive scheme that minimizes power dissipation by reducing the operating frequency at which columns (12) operate. The operating frequency is reduced by positioning column timing signals (32) near an end of a horizontal display time (38,39,48,49) if the next horizontal display time also has data to be displayed.
Abstract:
A filter arrangement for use with a vessel that receives fluid includes a body engageable with the vessel. The body has an inlet port, an outlet port, a body cavity, a first fluid path disposed between the inlet port and body cavity, and a second fluid path disposed between the body cavity and the outlet port. A filter is disposed at least partially in the body cavity, and includes a filter cavity and filter media for filtering the fluid. A valve is associated with the body for allowing the fluid to flow into and out of the vessel. When the fluid flows into the vessel, the fluid flows through the filter cavity and along the first fluid path without flowing through the filter media. When the fluid flows out of the vessel, the fluid flows along the first fluid path, through the filter media and along the second fluid path.
Abstract:
An array of thin film piezoelectric resonators are formed on a substrate and connected in parallel to form a single piezoelectric resonator with enhanced piezoelectric coupling. The array includes a first conductive layer positioned on the substrate and defining a first electrode, a plurality of columns of piezoelectric material positioned on the conductive layer and each defining a separate piezoelectric resonator, and a second conductive layer positioned on the plurality of columns and defining a second electrode. The columns are selectively deposited or deposited as a single layer and etched into columns.
Abstract:
A display (10) includes an electron source having a row conductor (17) that utilizes a plurality of longitudinal elements (26, 28). Each longitudinal element (26, 28) has extraction section (19, 23) that extends from the longitudinal element toward an adjacent longitudinal element. The longitudinal elements (26, 28) are electrically connected by a plurality of transverse connectors (29, 38, 39). When a short occurs between the row (17) and an underlying column (12, 36), the shorted portion can be electrically isolated so that the remainder of the row remains functional.
Abstract:
A digital video word (14) that is utilized to specify an image to be displayed by a field emission device is divided into a plurality of digital subwords (16, 17). Each digital subword (16, 17) is utilized to create a control signal (21, 22) that is applied to an input (23, 26, 32, 33) of a drive source (24, 27, 31). The digital subwords (16, 17) divide the control signals (21, 22) into time slots wherein each time slot has a duration that is greater than the duration of time slots represented by the original digital video word (14). In response to the control signals (21, 22) the drive source (24, 27, 31) provides a drive signal (28, 34) that has an output value and duration that is controlled by the duration of the control signals, and by an active and inactive state encoded by the control signals.
