Abstract: A resistance-generating device includes a resilient body extending between opposed ends. The resilient body has a first portion extending between first and second mounting members of the device, and a second portion extending between the first and second mounting members. The first portion is spaced apart from the second portion, and the first and second mounting members are made of an inelastic material. At least one of the first and second mounting members is removably mountable to a corresponding one of the first and second mounting members of another resistance-generating device. The resilient body generates resistance upon the first and second portions being elastically deformed by displacement of the second mounting member mounted to a second structure relative to the first mounting member mounted to a first structure.

Abstract: A sensor detects the presence of an upper cup in a pair of cups, between which pills are crushed by machine. Operation of the crushing machine is prevented if the upper cup is absent, and enabled if the upper cup is present. The sensor may be a photodiode that is sensitive to a beam of laser light that is directed over the lower cup. The beam passes when the upper cup is absent and is blocked by the upper cup when present. An optional sensor may be included to detect whether the drawer containing the cups and pills is closed, which is used as a further condition that must be satisfied before crushing can be started. Also, an interlock can be included to prevent the drawer from opening during the crushing process. By ensuring the presence of the upper cup, the escape of powdered medication can be prevented.
