Title: Safety sheath for needles, sharp instruments and tools
Inventor: ORGAIN PETER A
IPC: A61M5/32
Filed: 1991-05-16
Abstract: A reusable arrangement to protect against accidental contact with the surfaces of needles and other invasive medical instruments. In one embodiment, the invention comprises a collar that engages a sharp surgical instrument in advance of its sharp end. Attached to the collar by means of a flexible hinge is a slotted longitudinal member (21), which swings over the sharp end of the instrument, thereby engaging either the collar or the portion of the instrument just in front of the collar and also retaining the instrument behind a keeper shelf (44).      In second and third embodiments, the collar extends into an arcuate sheath, which is molded to assume a rest position that bends away from the sharp end of the instrument. This arcuate sheath ultimately forms an elbow curl (52) and extends back toward the collar, thereby forming upper and lower arcuate portions. The lower portion terminates in a set of flanges (56) that help define a trough (54) to carry the sharp end of the instrument. In a fourth embodiment, the keeper shelf (44) is modified so that it may be engaged with the opposite side of the longitudinal member (21) to lock this member over the sharp instrument. The longitudinal member may also be equipped with wing member (92) to facilitate movement of the sharp instrument around the keeper shelf (44). In a fifth embodiment, the locking mechanism comprises a set of flanges (97) depending from the longitudinal member (21) that are gripped by complementary catches (98) on the collar when the device is placed into the closed position.

Patent CA-2387200-A1 (CA)
Title: Implementation of thread-static data in multi-threaded computer systems
Inventor: HURAS MATTHEW A
IPC: G06F9/40
Filed: 2002-05-22
Abstract: One of the primary difficulties that result from using static variables in multi-threaded computer programs is that changes to a static variable made by one thread will be seen by all other threads operating within the same process. Multiple threads cannot use static variables separately because other threads within the process can overwrite the values stored at the variable memory location. Thus, the development of multi-threaded programs using static variables often requires explicit thread harmonization by the programmer. Another problem is that threads within the same process must use unique static variable IDs to avoid reading or writing to the location of another static variable. This also requires thread harmonization by the programmer. Accordingly, in view of the shortcomings associated with existing thread-static data implementations, there remains a need for an efficient thread-static data implementation that can be used on most modern operating systems. The present invention provides embodiments of a method, data processing system, and computer program product that efficiently implements thread-static data without registering pointers. The present invention efficiently implements static thread data in a multi-threaded program. The static thread data of each thread is allocated to the top of the virtual memory block belonging to the corresponding stack of each thread. An address mask is created for each thread so as to extract the base address of the static thread data region of the stack for each thread from the corresponding stack pointer. When a thread in execution needs to access its static thread data, it accesses the static thread data variable according to the virtual memory address extracted from the stack pointer using the address mask.
