Abstract: A system and method for reduction of power consumed by a searchline buffer and control circuit during a CAM search-and-compare operation. The data buffer circuit samples one bit of a search word and a mask bit for driving a pair of complementary searchlines with the appropriate logic levels. The complementary searchlines are precharged to a mid-point voltage level between the high logic level voltage and the low logic level voltage during a precharge phase. The mid-point voltage level is applied on each searchline by sharing charge from the searchline at the high logic level voltage with the searchline at the low logic level voltage. Additional control logic compares the searchline data of the current search- and-compare operation with the next search-and-compare operation, to inhibit searchline precharging when both searchline data are at the same logic level.

Title: Lithographic imaging with non-ablative wet printing members
Inventor: LANGLAIS EUGENE L II
IPC: G03F7/00
Filed: 2001-04-10
Granted: 2005-10-04
Abstract: Lithographic imaging using non-ablative printing members combines the benefits of simple construction, the ability to utilize traditional metal base supports, and amenability to imaging with low-power lasers that need not impart ablation-inducing energy levels. A representative printing member has a topmost layer that is ink-receptive and does not significantly absorb imaging radiation, a second layer thereunder that is hydrophilic and does absorb imaging radiation, and a metal substrate under the second layer. The printing member is selectively exposed to laser radiation in an imagewise pattern, and laser energy passes substantially unabsorbed through the first layer and is absorbed by the second layer. Heat builds up in the second layer sufficiently to detach the first layer, which is formulated to resist reattachment. But the first layer and, more significantly, the third layer act to dissipate heat from the second layer to prevent its ablation. Where the printing member has received laser exposure - that is, where of the first and second layers have been detached-remnants of the first layer are readily removed to produce a finished printing plate.

Abstract: Methods of extracting and removing hyperpolarized gas from a container include introducing an extraction fluid into the container to force the hyperpolarized gas out of an exit port. The hyperpolarized gas is forced out of the container separate and apart from the extraction fluid. Alternatively, if the fluid is a gas, a portion of the gas is mixed with the hyperpolarized gas to form a sterile mixed fluid product suitable for introduction to a patient. An additional method includes engaging a gas transfer source such as a syringe to a transport container and pulling a quantity of the hyperpolarized gas out of the container in a controlled manner. Another method includes introducing a quantity of liquid into a container and covering at least one predetermined internal surface or component with the liquid to mask the surfaces and keep the hyperpolarized gas away from the predetermined internal surface, thereby inhibiting any depolarizing affect from same. Examples of surfaces or components suitable for masking include valves, seals, and the like. Yet another extraction method includes expanding a resilient member inside the container to force the hyperpolarized gas to exit therefrom.  Containers include a resilient member positioned in fluid communication with the hyperpolarized gas in the container. An additional container includes inlet and outlet ports in fluid communication with the chamber and positioned on opposing sides or end portions of the container. Another container includes a port configured to receive a portion of a syringe therein. An additional aspect of the disclosure relates to calibration methods and apparatus for identifying the hyperpolarization status of the gas.

Title: Method of calculating oxygen required and system for monitoring oxygen supply and/or calculating flight level after emergency cabin decompression
Inventor: STABILE JAMES R
IPC: B64D13/00
Filed: 2001-07-26
Granted: 2011-09-27
Abstract: A system useable in a jet aircraft having installed therein a pressurized oxygen supply which feeds oxygen into the interior of the plane when it flies at high cabin altitudes, the system indicating the changing status of the supply as oxygen is drained therefrom. The system includes a pressure transducer coupled to the supply and means associated with the transducer to determine the lapse rate at which the pressure of the supply is reduced as oxygen is drained therefrom to yield a first signal representing this pressure lapse rate, and to concurrently determine the lapse rate at which the number of liters of oxygen in the supply is reduced as oxygen is drained therefrom to yield a second signal representing the liter lapse rate. These signals are applied to a microprocessor in whose data base is entered the total oxygen inventory of the supply and the oxygen demand of the plane in which the supply is installed. When oxygen is being drained from the supply, the microprocessor calculates and reads out the prevailing supply pressure, the number of liters remaining in the supply, and the time in hours and minutes remaining before the supply is exhausted based on the current rate of oxygen consumption. The invention provides both a method for calculating the oxygen required, as well as a real time monitoring and calculating system for emergency conditions. The invention is applicable to any pressurized gas system, such as for divers, compressed gas cooking or vehicles, therapeutic oxygen, and the like.

Granted: 2008-02-12
Abstract: A non-contacting thickness measurement apparatus is described, which is capable of on-line, highly accurate web thickness measurements. The apparatus is comprised of a first and second distance determining means which calculate a distance value from each distance determining means to the web surface. The distance determining means are on opposite sides of the web, so each measures the distance to a different side of the web. At the same time, the distance between the two distance determining means is measured to produce a z-sensor spacing value. The two distance values are thereafter subtracted from the z-sensor spacing value to get a web thickness value. An x-y position adjustment means is used to keep the measurement spot on the web for the two distance determining means at the same location on the web, and several techniques are combined to eliminate temperature-induced and/or other unknown variations or drifts in the web thickness value which are not caused by actual changes in the thickness of the web.

Abstract: A plow assembly for vehicles, such as pickup trucks and tractors, or bulldozers or graders, for moving snow or other plowable materials has at least one extendable, forwardly pivotable plow wing which is pivotable at a hinge at one end of a main plow for movement between an aligned position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. The plow wing includes an inner and outer portion, whereby the outer portion is slidably mounted to the inner portion for sliding movement along the inner portion between a retracted and an extended position. One or more actuators, such as fluid power cylinders or the like, are connected to the plow wing to move the wing between the retracted, -extended, aligned and forwardly angled positions. In one preferred embodiment, an extendable plow wing is pivotally mounted on each end of the main plow with a pair of fluid cylinders connected to each of the respective plow wings. The fluid cylinders in each respective pair are operable independently of one another to move the plow wings independently between their respective retracted, extended, aligned and forwardly angled positions. When both plow wings are pivoted to their forwardly angled positions, the plow assembly has a general U--shape which facilitates pushing snow or other material without the material slipping off the plow blade ends. The wings are extendable and retractable when the plow is in the U-shape in order to adjust the carrying capacity of the plow.
