Abstract: By encoding an exception triggering value in storage referenced by an instruction in an otherwise unused slot (e.g., the delay slot of a delayed control transfer instruction or an unused instruction position in a VLIW-based architecture) coinciding with a safe point, an efficient coordination mechanism can be provided for multi-threaded code. Because the mechanism(s) impose negligible overhead when not employed and can be engaged in response to an event (e.g., a start garbage collection event), safe points can be defined at call, return and/or backward branch points throughout mutator code to reduce the latency between the event and suspension of all threads. Though particularly advantageous for thread suspension to perform garbage collection at safe points, the techniques described herein are more generally applicable to program suspension at coordination points coinciding with calls, returns, branches or calls, returns and branches therein.

Abstract: A three-prong retractor is disclosed which is inserted into an incision in a patient in order to create an area for surgery. The retractor opens such that two blades move away from a first blade to create an elongated opening. The two blades may then move away from each other in a direction that intersects the direction of the movement of the first blade away from the two blades. The ends of the two blades remote from the retractor body may then move away from the end of the first blade remote from the retractor body to further open the incision. The retractor may also have an elastomeric sheath surrounding the blades in order to create a barrier between the surgical area and the patient's skin.

Abstract: Mechanisms can be used to facilitate suspension of a mutator thread (or mutator threads) while imposing negligible overhead on the mutator computation during periods when thread suspension is not requested. Mechanisms are provided to spill values from a fixed set of resources to a secondary store and to fill values from the secondary store into the fixed set in correspondence with function call triggered overflows and function return triggered underflows. In some configurations, modified spill and/or fill mechanism(s) are used to suspend threads at safe points coinciding with call and/or return sites. Because the modified spill and/or fill mechanism(s) impose negligible overhead when not employed and can be engaged in response to an event (e.g., a start garbage collection event), safe points can be defined at call and/or return points throughout mutator code to reduce the latency between the event and suspension of threads.

Abstract: An improved method and system for diagnosing faults of a system under test is provided. One or more candidate diagnoses potentially responsible for observed testing failures are generated. Each candidate diagnosis is then assigned a weight based in part on any of a number of factors not previously considered in the weighting process, thus making the weighting process more accurate. In one case, the weight of a diagnosis may be based on the combined consistent utilization of the candidate diagnosis across all failing system tests. Alternately, or in addition, that weight may be based on the combined utilization of the diagnosis among all passing system tests. Other potential factors may also be used.

Abstract: In processor architectures that support allocation of register windows to called procedures, functions or methods, register windowing mechanisms can be used to facilitate suspension of a mutator thread (or mutator threads) while imposing negligible overhead on the mutator computation during periods when thread suspension is not requested. Reduced Instruction Set Computer-(RISC)-oriented processor architectures often employ register windows (typically partially-overlapped register windows) and can therefore benefit from the technique. Variations can be employed even in processors (RISC or otherwise) that do not employ register windowing as long as the processor (by itself or in cooperation with software) provides facilities for allocating and reclaiming resources in correspondence with calls to, and returns from, procedures, functions or methods.

Abstract: The invention provides a method of creating and periodically loading a database of classfiles on a non traditional computer device, such as a PDA (personal digital assistant), cellular telephone, pager, appliances, or other embedded device. A resident Java virtual machine loads classes from this database instead of loading them from a file system. The embedded device is periodically updated by connecting it to a network or computer that includes a classfile source. At this time, records can be added to, or deleted from, the database (where the records are classfiles). The management of the classfile database on the embedded device is independent of the virtual machine on the embedded device. One embodiment of the invention comprises an embedded device with a virtual machine, a classfile database, a database manager, and a remote database loader. The embedded device and virtual machine can function even when not connected to the classfile source.

Abstract: An improved motor protection switch incorporates a parallel feedback component mounted in parallel to a heater in a motor protection circuit. The parallel feedback component senses the temperature of a compressor component. If tie temperature increases then the current flow through the heater increases. This causes a motor protector switch to open. In this way, the feedback component provides feedback from the compressor pump unit to the motor protection circuit more quickly than in the prior art.
