A system for reforming diesel fuel into hydrogen including feeds for water and diesel fuel, a supercritical water (SCW) reactor in fluid communication with the water feed and the diesel fuel, at least one pre-heater in thermal communication with the water feed, the diesel fuel feed that is configured to heat water from the water feed and diesel fuel from the diesel fuel feed to a predetermined temperature equal to or greater than the critical temperature of water before the water and the diesel fuel are mixed, a water-gas shift (WGS) reactor, and a hydrogen capturing system, where the SCW reactor reforms the diesel fuel into a synthesis gas comprising a mixture of hydrogen and carbon monoxide and outputs the synthesis gas, the synthesis gas output by the SCW reactor is fed into the WGS reactor which converts the carbon monoxide into carbon dioxide and hydrogen and outputs an output gas including a higher percentage of hydrogen to carbon monoxide compared to the synthesis gas, and the hydrogen in the output gas is captured by the hydrogen capturing system.
摘要:
A digital pressure controller that utilizes a microprocessor provides for control of the speed of a fluid pump engine for the purpose of maintaining specified pressures at both the inlet and outlet of the pump. Based upon pressure sensor output, and computations based on multiple calibrations between pump speed and pressure, and between output voltage and pump speed, a pump drive mechanism speed is determined by the control logic of the microprocessor, which speed maintains at least one of the inlet and outlet pressures within a specified range. The microprocessor may determine the specific weight of the fluid being pumped in order to select the pump drive mechanism speed.

Monitoring and controlling apparatus and related methods for use with collective protection shelters or other isolation environments utilizing one or more digital processors to monitor and control the operation of the shelter. The apparatus affords shelter design and functional growth flexibility, along with diagnostic and prognostic capability, including condition based maintenance, interactive electronic manuals, and access to systems for replacement parts requisition. Further, the physical and functional expandability of the apparatus affords easy incorporation of shelter design changes, user interface design changes, and sensor design changes as well as improved functional and operational flexibility. The system also decreases volume and weight over prior designs.

A traffic incident detection system (10) includes both the collection and analysis of traffic data and employs a time-indexed traffic anomaly detection algorithm which partitions time into categories of “type of day,” and “time of day”. Using this partition, a fuzzy neuromorphic, unsupervised learning algorithm calibrates fuzzy sets as “normal” and “abnormal” for a plurality of traffic descriptors. Fuzzy composition techniques are used, on a per traffic lane basis, to combine multiple traffic descriptors in order to determine membership in a “normal” or “abnormal” lane status. Each lane status is then combined to determine the overall status of a road segment. Initial training of the algorithm occurs during the first few weeks after a sensor (12) is installed. On-line background training continues thereafter to continually tune and track seasonal changes affecting system performance.
摘要:
A supercritical water reformer (SCWR) and methods for using supercritical water to convert hydrocarbons, particularly hydrocarbon fuels such as diesel fuel or gasoline, into carbonaceous gases and hydrogen. The synthesis gas stream generated by the fuel reforming reaction can then be further refined to increase hydrogen content, and the resultant hydrogen can be utilized to power fuel cells.

A dual compartment cooling device that is designed to cool water, or other beverages, as a batch based on expected demand. This provides for the cooling of beverages which are to be consumed in a subsequent demand cycle at which time it is refilled but allows remaining water to remain “hotter” until it is to be in the next dispense cycle, which results in power savings

Apparatus (30) controlling the temperature within a sealed enclosure (10) housing electronic components (E) whose operation produces heat, and whose operation should occur within a desired temperature range. A heat sink (32) extending through an enclosure endwall (14) conducts heat from within the enclosure to the atmosphere. Other heat sinks (40) mounted within the enclosure are in a thermal transfer relationship with the components for heat generated by the components to be drawn to the heat sinks away from the components. A heat pipe (50) extending between the respective heat sinks conducts the heat to the first said heat sink for heat to be expelled from inside the enclosure to the atmosphere. A heater (60, 62) within the enclosure generates heat to heat the components, and a thermostat (72, 74) senses when the temperature within the enclosure falls below a predetermined temperature to energize the heater. Heater is sized to cause a “dry out”, condition in the heat pipe when the thermostat energizes the heater. As a result, the temperature in the enclosure is maintained within the desired range by appropriately removing heat, from or generating heat within, the enclosure and controlling the heat transfer path.
