Abstract: A method for supporting speculative execution includes designating operations as speculative or non-speculative, and then deferring exceptions generated by speculative operations while immediately reporting exceptions by non-speculative operations. If a speculative operation uses a result of a speculative operation that has generated an exception, the exception is propagated. Deferred exceptions are detected and reported using a check operation either incorporated into a non-speculative operation or inserted as a separate check operation. A system for supporting speculative execution includes a functional unit for recognizing a speculative operation and deferring any exceptions generated by such an operation. The functional unit may defer an exception by storing information indicating an error has occurred in the register file. To check for deferred exceptions, the functional unit then reads the register file.

Abstract: Apparatus for superposing a receiver sheet and a donor sheet on an imaging drum communicates vacuum from the interior of the drum to the exterior surface. A leading edge of a receiver sheet is advanced into alignment with a predetermined position on the drum surface while being held radially off of the drum surface. The drum is rotated to thereby draw the receiver sheet into contact with the drum surface. Next, a leading edge of a donor sheet is advanced into alignment with a predetermined position on the drum surface while being held radially off of the drum surface. The drum is again rotated to thereby draw the donor sheet into contact with the drum surface. The leading edge of the receiver sheet and the donor sheet are held radially off of the drum surface until aligned with the predetermined position, and thereupon is lowered radially onto the drum surface.

Abstract: A collision detection method and apparatus that detects the likelihood of a collision with an address of data previously retrieved from a two dimensional memory array, such as a memory array suitable for use as the frame buffer memory within a graphics display sub-system of a computer system. The collision detection system can also view the memory as having only one dimension to detect the likelihood of a collision with higher or lower accesses relative to a current access.

Abstract: A full optical type optical element performs an information processing on an input signal light beam through use of only light beams including the signal light beam and an auxiliary light beam for assisting operation. The optical element includes aggregates which are dispersed within the optical element as optical functional aggregates, and which are composed of a single kind or multiple kinds of compounds including a single species of atoms or molecules. Thus, a full optical type optical element having a high resolution can be obtained through use of a thin-film element which contains nanoparticles comprising molecules of an organic compound and associates/aggregates of these molecules.

Abstract: Absorbent articles, such as disposable diapers, having two waist regions and a crotch region are provided. The absorbent articles comprise a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinally extending barrier cuffs. The barrier cuffs are formed from a lateral extension of the topsheet and the backsheet in at least the crotch region of the absorbent article using material that is normally discarded when the crotch area is formed. A cuff area is defined by pairs of laterally opposed cuts in the lateral extension of the topsheet and the backsheet. The cuff area is then folded and joined to the topsheet or other underlying structure to form the barrier cuff and an optional gasketing cuff.

Abstract: A web (44) passes over an air bar (40) or metering drum, defines a loop (48, 50, 52) within an open space (46) defined between two pneumatic tensioning wall members (14, 16), and passes over an air bar (42) or metering drum. Pressurized air issues through apertures (36) arranged in rows along web control surfaces (32, 34) to establish curtains of air flowing between the surfaces and the web, thereby applying tension to the web due to the Bernoulli and viscous drag effects.

Abstract: Methods and systems for performing a tomographic scan which allow an operator to define a non-circular orbit so that a detector can be positioned close to a patient at each view are described. Such methods and systems provide that the patient to detector distance is reduced, which improves spatial resolution for the scan. In one embodiment, and to achieve a non-circular orbit, the camera and table/patient are moved with respect to one another. Specifically, the table is pinned in position and set to lateral and vertical positions during set-up. The same lateral and vertical table positions are maintained during the scanning phase. To get the camera closer or farther from the patient/table, the camera is pitched in or out. The camera head is tilted to achieve a tilt angle of zero degrees for all changes in pitch. As the camera pitches in and out, the central axis of the camera moves along the longitudinal axis of the table.

Compounds with the low pKa phenolic substituent provide improved coupling activity when used with a photographic element and improved contrast.

Abstract: An automated sensor transport system for non-destructive inspection of a weld through the use of ultrasonic waves produced by an electromagnetic acoustic transducer (EMAT). The system includes: a computer control unit; a transport apparatus having a first EMAT for producing an ultrasonic SH shear wave and a second EMAT for receiving an ultrasonic SH shear wave reflected from a weld and a calibration means. The computer control unit, which is in electrical communication with a welding apparatus, the transport apparatus and a data acquisition unit, coordinates the weld test with completion of the weld. An edge detection sensor, which is affixed to the transport apparatus is used to automatically position the transport apparatus for a weld scan and to signal completion of the scan. The system includes an electrostatic shield to protect the second EMAT from electromagnetic and radio frequency interference.

Abstract: A straw discharge assembly allows the beater to reach further towards the rotational axis of the threshing rotor, thus enabling it to remove a greater percentage of the straw which otherwise collects on the housing frame members. The beater has a barrel-shaped body, but it takes on an hourglass shape as it is divided into a center section with shorter blades and two side sections with longer blades, giving the center section a smaller effective diameter than the two side sections. The beater does not interfere with the rotational path of the rotor housing frame even though it is effectively closer to the housing frame. With their longer blades, the side sections are closer to the rotating frame legs and can therefore pull down and discharge more of the obstructed straw. The discharge grate is conformed to the effective shape of the rotor in a similar fashion.

Abstract: Substantial improvements in the control of pollutants from internal combustion engines may be obtained by pre-drying a catalyst/hydrocarbon trap system and preferably incorporating a water trap in a catalyst/hydrocarbon trap system. A pre-drying system dries the water trap, HC trap and catalyst, eg upon engine switch-off.

Abstract: The monitor for uncommanded braking controls uncommanded brake application on one or more wheels during takeoff of an aircraft. Brake pedal application is determined, brake pressure is measured, and brake pressure is compared with a selected threshold brake pressure. A brake pressure applied signal is generated when the brake pressure exceeds the threshold brake pressure. The pedal application signal and brake pressure applied signal are received by a fault latch logic circuit that generates a fault latch output signal when uncommanded braking has occurred. A test inhibit signal is also generated when weight is not applied on the wheel. The test inhibit signal is also input to the fault latch logic circuit so that uncommanded braking can occur when the aircraft is in the air and weight is off the wheel. The monitor disables or latches off the shutoff valve when pressure is detected without pedal application.
