Abstract: The present invention relates to a system for calculating a digital quality index (DQI), which provides a rating on a predetermined scale, indicative of the impairments in a received quadrature amplitude modulated (QAM) signal in a CATV cable system. The DQI system utilizes bit error rates prior to and after forward error correction to calculate the DQI value. To increase the calculation rate, the bit error rates can be estimated using voltage errors, signal to noise ratios and/or average corner error metrics.

Abstract: A gateway is used to segment a network, such as a Fault Tolerant Ethernet (FTE) network, into islands. The gateway receives traffic from a first island, forwards part of the traffic to a second island, and blocks another part of the traffic from being forwarded to the second island. The forwarded traffic could include unicast traffic. The blocked traffic could include broadcast or multicast traffic, including diagnostic messages from one or more nodes in the first island.

Abstract: A system for handling data of a process with a primary controller and a redundant controller. The primary controller includes a primary processor that is operable to perform tracking data tasks by using a low speed bus to cooperate with a tracker controller for storage of tracking data in a tracker memory. The primary processor is further operable to perform other tasks by using a high speed bus in cooperation with a primary memory. The second bus has an operating rate considerably higher (for example, by a factor of two or more) than that of the first bus. The primary controller provides tracking data items that each comprise a current data and a current address. The tracker controller accesses the tracking memory using the current address to read a stored data and write the current data. If the current data differs from the stored data, the current tracking data item is written to a buffer. The tracking controller generates an interrupt when the buffer contains a predetermined number of tracking data items.

Abstract: A gas operated part forming die apparatus has compact high tonnage presses which are operated by high pressure gas generated within chambers and controlled to operate high pressure pistons and dies for compressing particulate material into dense formed parts. Combustion chambers are filled with pressurized mixtures of combustible gases and diluents. Elongated chambers have insulating walls and spaced electrodes. Some contain liquid or particulate ablatable materials or ablatable liners. Others extend fuzes between the electrodes and are filled with pressurized gases. Gas is removed from the particulate material. Die cavities may be precompressed during filing of chambers with pressurized gas. Igniting the combustible gases or creating arcs between the electrodes produces rapidly expanding high pressure resultant gases for driving pistons and movable dies and rapidly compressing die cavities. Pressures in the chambers are contained, or pistons are restrained until releasing and driving the pistons.

Abstract: A portable liquid-solid separator tank has a bed, surrounding exterior walls, a dividing wall. The exterior walls of the tank include a gasket door to allow easy removal of the filtered sludge. The exterior walls of the tank support sludge include inlet valves where the sludge is provided by a hose from a storage and/or mixing tank. The exterior walls also include a liquid outlet valve or valves for the filtered liquid to be removed and roller wheels that enable the tank to be easily transported. The tank contains a filter media mounted on a filter media support structure supported by the interior of the bed, exterior walls, and the dividing wall. The filter media support structure is composed of perforated metal supports and expanded metal supports. The use of the expanded metal supports in the filter media support structure increases the opening space in the support structure and reduces the amount of time it takes to filter the sludge.

Abstract: A pulsed electrothermal powder spray apparatus and method increases coating particle velocities to the 2,000-4000 m/sec range. The apparatus includes a containment tube, which may be a reverse shock tube, having a capillary chamber section and a short barrel section. The tube is initially filled with an inert gas and powder is deposited in the barrel just downstream from the barrel's connection to the confined capillary discharge chamber. On receipt of a trigger signal, the muzzle shutter of the barrel section quickly opens, causing the inert gas to flow towards the open end of the barrel. A rarefaction wave propagates back up the barrel, towards the capillary chamber. Once the rarefaction wave reaches an electrode positioned at the front end of the capillary chamber, an arc discharge is triggered in the capillary, resulting in a quick rise in capillary temperature and pressure.

Abstract: Wire arc spraying using repetitively pulsed, high temperature gas jets, usually referred to as plasma jets, and generated by capillary discharges, substantially increases the velocity of atomized and entrained molten droplets. The quality of coatings produced is improved by increasing the velocity with which coating particles impact the coated surface. The effectiveness of wire-arc spraying is improved by replacing the usual atomizing air stream with a rapidly pulsed high velocity plasma jet. Pulsed power provides higher coating particle velocities leading to improved coatings. 50 micron aluminum droplets with velocities of 1500 m/s are produced. Pulsed plasma jet spraying provides the means to coat the insides of pipes, tubes, and engine block cylinders with very high velocity droplet impact.

Abstract: Paint is removed from bridges and structures by directing pulsed plasma jets at coatings on surfaces. The repetitively pulsed plasma jets ablate the coatings, and the resulting products are removed by reduced pressure in an enclosure. Plasma jets in an array are moved along a surface, with the jets overlapping. Power is controlled to remove the topcoats and one or more layers of topcoat without damaging an underlying primer coat, or to remove a primer coat to the bare surface. Jets in the array overlap to completely remove the coating. The pulsed plasma jets impact the surfaces directly in front of the plasma jets, and the gases flow outward, carrying ablated materials away from the surfaces. The enclosures have openings near the coated surface for allowing the inflow of ambient air into the reduced pressure enclosure to prevent escape of ablated products from the enclosure. The use of inert gas working fluid reduces formation of undesirable byproducts.

Abstract: Repetitively pulsed plasma jets generated by a capillary arc discharge at high stagnation pressure (>15,000 psi) and high temperature (>10,000 K) are utilized to produce 0.1-10 .mu.m sized metal powders and decrease cost of production. The plasma jets impact and atomize melt materials to form the fine powders. The melt can originate from a conventional melt stream or from a pulsed arc between two electrodes. Gas streams used in conventional gas atomization are replaced with much higher momentum flux plasma jets. Delivering strong incident shocks aids in primary disintegration of the molten material. A series of short duration, high pressure plasma pulses fragment the molten material. The pulses introduce sharp velocity gradients in the molten material which disintegrates into fine particles. The plasma pulses have peak pressures of approximately one kilobar. The high pressures improve the efficiency of disintegration. High gas flow velocities and pressures are achieved without reduction in gas density.

Abstract: A patient transfer stand is provided for assisting a wheelchair-bound person to transfer to and from a wheelchair to a variety of other points in a simple fashion. The transfer stand includes a rotating base. The base includes 2 substantially rectangular cut out portions that accommodates the wheels of the wheelchair. The base supports a pair of vertical support bars, in addition to an elevated handle structure that the wheelchair-bound person can hold onto during transfer. The elevated handle structures include elastic straps which may be used to assist the wheelchair-bound person from the wheelchair into the patient transfer stand. A patient, if required, may utilize the elastic straps attached to a belt or harness worn about the waist to assist them in assuming a standing position inside the transfer stand. Through the utilization of developed leverage, the patient may assume a raised or semi-standing position in the transfer stand without assistance.
