Abstract: A heat sterilizer sterilizes a load held in a sterilizing chamber at a predefined temperature over a shortened sterilization period by using predefined heating and cooling profiles. The sterilizer includes a temperature sensor coupled to a controller for sensing the temperature within the sterilizing chamber, where the controller is further adapted to monitor an output of the temperature sensor and maintain the temperature within the sterilizing chamber according to the predefined heating profile, the predefined temperature, or the predefined cooling profile, and where the controller is further adapted to specify an error condition if the controller fails to maintain the temperature within the sterilizing chamber according to the predefined heating profile, the predefined temperature, or the predefined cooling profile.

Abstract: Foot retainer (11) has a pair of flexible PVC straps (14) and (15) joined at their upper ends to form headpiece (19). Batten (21) is connected to headpiece (19) and base (26). Headpiece (19) rotates between a prone position and an upstanding position. The retention assembly is biased to its upstanding position by an elasticized tensioner (22). The base (26) is bonded to the back face of a velcro-like surface for attachment to a surfboard. In an upstanding attitude batten (21) is inclined upwardly at an acute angle to base (26) to form a jaw into which straps (14) and (15) can move under the sideways action of a rider's foot. This action against straps (14) and (15) causes headpiece (19) to pivot and move downward to partially envelop the upper area of the foot which is thus retained by the assembly.
