Abstract: A lockable electrical outlet socket closure plug includes a plug housing including an inner plate and a socket blade appended to the inner plate and adapted to extend into a blade receiver opening formed in the electrical outlet socket. The closure plug further includes a retainer for selectively retaining the plug housing in a mounted position on an electrical outlet socket and a controller mounted for movement in the plug housing and arranged normally to reinforce the retainer to cause the plug housing to remain in the mounted position on the electrical outlet socket.

Abstract: A latch for a cabinet door or drawer for preventing access to the interior of the cabinet or drawer. The latch includes a hook spring biased to engage a catch and that allows the door or drawer to be only slightly opened enough to allow a caregiver to reach the latch and displace it out of the way so that the door or drawer can then be fully opened. When released the latch returns to the biased position. The latch may also disengage the spring so as to be fully disabled and allow the door or drawer to be opened freely.

Abstract: A security gate for closing a passage has a pair of panels movable translationally with respect to one another to alter the effective width of the gate. An actuating mechanism for forcing the opposite ends of the panels against the sides of the passage includes a handle mounted on one of the panels controlling a latching device operative for locking the handle in a fixed relationship with respect to the other of the panels. The latching device in accordance with one embodiment includes a rack and brake. When the latch is engaged, a cam also controlled by the handle engages the panel on which the handle is mounted to force the two panels translationally further apart so as to bear firmly against the sides of the passage to hold the gate in position.

Abstract: A computer software tool used for automatically identifying code portions and data portions of a binary executable software program in which the code portions include machine instructions that are of arbitrary length. Software products are typically distributed as binary, executable files, which comprise a string of binary values. In general, an executable file has no structure or meaning, except as determined by its behavior when dynamically executed, one instruction at a time, by a digital computer. The software tool determines a set of addresses for any known code and data portions. The tool is then used to disassemble machine instructions, beginning at a starting address for each known code portion, to identify the target addresses of other code portions and other data portions. Other sections of the binary executable software program that could be either code or data are then analyzed to identify additionAL code and data portions.

Abstract: A method and procedure for modifying modules comprising a binary executable software program in such a way that, despite the transformations performed and the creation of new versions of the modules, the transformed program appears (to that program, including all of its components) as if it is running in the identical environment as the original program. The environment includes environment variables, the name of the program, the names of all of the dynamically loaded library (DLL) files that the program references, the directory in which the program resides, and the current directory at the time the program started execution. When the program has been transformed, e.g., for the purposes of monitoring or measurement, the environment also includes the effective addresses of data and instruction references made by the program.
