Abstract: Dynamically allocated memory is managed in real-time. This real-time management capability enables an invalid access of the dynamically allocated memory to be detected at the time the invalid access occurs, rather than at some later point in time. This real-time management capability can be dynamically activated/deactivated on a per process basis.

Abstract: A spinous process spacer implant for relief of back pain is disclosed. The implant, a generally H-shaped device having grooved ends, is made of human allograft or other suitable artificial or natural material. It is sized for implantation between and optional attachment to adjacent spinous processes. The implant may be hollow in the center to allow for addition of suitable biological material.

Abstract: An occupancy sensor device has a housing with a neck entry affording a light path to a recessed sensor. The interior of the light path has properties of reflection and/or refraction to improve effective field of view of the sensor. A tubular member as the neck can be angularly adjustable for selective electrical connection to a circuit board carrying the sensor and contacts at its end. That board can be clamped in slots in an inner part of the housing. Fitting to a barrier can be aided by clenching action of a spring member apertured to group an outer housing part when relaxed.
