Abstract: A system for monitoring the application and removal of physical restraints such as straps that may be used to restrain a patient in an institution or other medical facility, and recording data relating to the application and removal of such restraints. The system includes one or more portable monitoring units, each of which can be used for any one patient at a time, with the system including as many monitoring units as are necessary for the facility that uses such physical restraints. The monitoring units provide an accurate record of the times and dates during which each application and removal of such restraints are carried out.

Abstract: A photographic flash lighting unit includes a tubular housing which is preferably hexagonal in cross-section and is defined by a plurality of elongate side faces, each of the side faces are provided with a coupling formation and are divided into a first plurality of faces having a male coupling formation, and a second plurality of faces having a female coupling formation adapted to matingly engage the male formations of like flash units, the faces are arranged upon the housing so that the male and female coupling formations alternate thereon. Locking members are provided on selected faces of the housing to prevent relative movement of matingly engaged housings. The housing is further provided with a flash lamp and a connector and associated circuitry to enable a photographic power supply to be connected to the housing for energization of the flash. An optional adapter cord allows the unit to be powered by power supplies of domestic as well as foreign manufacture.
