A lock/unlock mechanism to control concurrent access to objects in a multi-threaded computer processing system comprises two parts: a thread pointer (or thread identifier), and a one-bit flag called a "Bacon bit". Preferably, when an object is not locked (i.e., no thread has been granted access to the object), the thread identifier and Bacon bit are set to 0. When an object is locked by a particular thread (i.e., the thread has been granted access to the object), the thread identifier is set to a value that identifies the particular thread; if no other threads are waiting to lock the object, the Bacon bit is set to 0; however, if other threads are waiting to lock the object, the Bacon bit is set to "1', which indicates the there is a queue of waiting threads associated with the object. To lock an object, a single CompareAndSwap operation is preferably used, much like with spin-locks; if the lock is already held by another thread, enqueueing is handled in out-of-line code. To unlock an object, in the normal case, a single CompareAndSwap operation may be used. This single operation atomically tests that the current thread owns the lock, and that no other threads are waiting for the object (i.e., the Bacon bit is "0'). A global lock is preferably used to change the Bacon bit of the lock. This provides an lock/unlock mechanism which combines many of the desirable features of both spin locking and queued locking, and can be used as the basis for a very fast implementation of the synchronization facilities of the Java language.

A method and apparatus for controlling the operation of a system having a plurality of video cameras. The cameras are linked to a control unit which has a motion detection apparatus for monitoring the images received from the cameras and detecting motion therein. The cameras are adapted to operate in at least two modes: a low resolution mode and a high resolution mode. Under normal circumstances, cameras will be operating in low resolution mode to minimize use of system resources. If activity is detected within the field of view of one of the cameras, that camera is switched to high resolution, the other cameras remaining in the low resolution mode.

An arrangement for the cooling of computer data centers. More particularly, the arrangement eliminates the problems present in the uneven or inadequate cooling of computer racks due to unwanted airflows, which are encountered between so-called hot aisles and cold aisles present in a computer data center. Specifically, this problem is solved through the provision of partitions which, under normal circumstances, prevent the unwanted airflows by standing in a vertical orientation, yet which, in the event of a fire, collapse from the vertical orientation to a horizontal orientation, thereby avoiding interference with water sprays from sprinkler heads, and thus complying with fire codes and ordinances. Moreover, also employed is a method of preventing the unwanted air flows by utilization of the novel arrangement comprising the fire-code-compatible, collapsible partitions.

When starting an engine, it is judged whether a catalyst is in an inactive condition or not and, if it is judged that the catalyst is in an inactive condition, the motor field current is reduced to control the output characteristic of the starter to a high-speed type, thus enabling the engine to be driven at high speed. As the engine rpm during driving rises compared with the normal case (the case where the catalyst is in an active condition), the amount of fuel remaining in the intake port and the cylinder decreases, and the injected fuel properly contributes to combustion. Accordingly, even when the catalyst is in an inactive condition, emissions (of HC) emitted into the atmosphere can be reduced.

Input MRI brain images are positioned so as to correct a spatial deviation, gray matter tissues are extracted from these images to effect a first image smoothing, the thus-obtained images are subjected to anatomical standardization, a second image smoothing is effected, the gray level is corrected, brain images after correction are statistically compared with MRI brain images of normal cases, thereby providing the diagnosis result. In this instance, the brain images are automatically checked for input images regarding the resolution dot density and the like, the result of gray matter tissue extraction and the result of anatomical standardization, by which specifications of input images and the like can be confirmed objectively and automatically to make a diagnosis automatically by image processing. Further, an ROI-based analysis is made to provide the analysis result as the diagnosis result.

The invention relates to an AC/DC overhead transmission line ice-melting technology which adopts split-phase conductors. When a line needs ice-melting, the load current which is evenly distributed in every split-phase conductor under normal conditions is transferred to one or more split-phase conductors; and when the centralized single conductor has the load current to a certain extent, the ice on the conductor can be melted. The deicing purpose can be realized by adopting the alternate switching manner by melting the ice on other split-phase conductors in sequence. If the manner is adopted before the line is iced, the purpose of line-icing prevention can be achieved.

A data repeating device that can maintain the data integrity in error-prone circumstances, without sacrificing the efficiency of data transmission in normal conditions. A network system involves a data communications device and a data repeating device interconnected via a transmission line. The data repeating device has an error detector for detecting a failure, based on errors found in received frames. Upon detection, a frame generator transmits an error correction enable frame to the data communications device, thereby requesting the use of error correction coding. Inside the data communications device, a correction activation flag is set in response to the received error correction enable frame, which indicates that error correction coding is to be applied. The active state of this flag permits an error correction coder to add an error correction code to each outgoing frame, thereby creating error correction coded frames for transmission over the transmission line.

The invention discloses a satellite orbit control method, and the orbit control of a satellite is achieved under a condition that attitude control engine of one of a yaw shaft and a rolling shaft works abnormally. First, two shafts working normally of attitude control engines are in conditional judgment in a momentum-wheel-unloading mode, when the shafts meet the condition of the momentum wheel unloading, the two shafts working normally of the attitude control engines are in momentum wheel unloading, shafts working abnormally of attitude control engines are in attitude control by adoption of momentum wheels, and when the two shafts do not meet the condition of the momentum wheel unloading, the momentum wheels are utilized for three-axis attitude control until the satellite three-axis attitude angle and the angular speed are both smaller than a set angle threshold value and a set angular speed threshold value. Then, orbit control time is calculated, and an orbit control engine carries out orbit control according to the calculated orbit control time. Rapid orbit maneuver can be achieved under the condition of under-actuation.

The invention relates to a deicing power transmission line of multiple conducting wires. Multiple (more than two but less than four) power transmission lines arranged in parallel in the same direction form a line set, wherein the lines are mutually separated and arranged in zones. Conducting wires at two ends of each line set of each zone are connected with a breaker respectively, and the breakers at two ends of each zone are communicated. Under normal condition, all breakers at two ends of each line set of each zone are switched on and powered, and the conducting wires do not heat. Once the conducting wires are iced heavily, when a section of the conducting wire needs to deice, one line in the breaker at any end of the line set is reserved, and the rest lines are switched off and not powered. Thus, only one conducting wire is switched on and powered to bear overall electric quantity of the line set, the current is increased and the line heats, and then the line melts ice so as to deice. In the same way, when the breaker is transformed, any conducting wire can melt the ice. When the ice is melted, the normal condition recovers.

A sheet-supply device supplying sheets one at a time from a stack of sheets in a sheet feeding direction. The device includes a slanting plate on which a stack of sheets is mounted. A sheet feed roller is positioned above the slanting plate applying a force to an uppermost sheet in the stack to move the sheet in a sheet feed direction. A fixed separation plate is fixed at a downstream end portion of the slanting plate. The separation plate is formed with a slot in which a high friction separation member is disposed. The high friction separation member is held by a resilient support plate 39 supported by the fixed separation plate. The resilient support plate has a comb like slats on which the high friction separation member is held. In a normal condition, the high friction separation member protrudes from the slot toward the leading edges of the sheets. When a leading edge of the sheet presses the high friction separation member by the rotation of the sheet feed roller, and the sheet has a predetermined stiffness, a part of the high friction separation member sinks into the slot by the deformation of the comb like slats.

When a heat capacity of a recording medium having a base material coated with a foamable resin layer is larger than a normal heat capacity, to form a raised amount equal to that with the normal case with a normal heating quantity, a turned mirror image of the image is generated. The image is transferred onto the front face of the recording medium and fixed. The recording medium is reversed, and conveyed again to the transfer part. The turned mirror image is transferred onto the rear face of the recording medium and fixed. The recording medium is heated with the heat quantity equal to that in the normal case, and combination of heat absorbed by the turned minor image and heat absorbed by the image is transmitted to the foamable resin layer to expand the foamable resin layer.
