    摘要: An improved foot orthotic is disclosed which includes an L-shaped boot and a sole plate which mat be mounted to the boot using a bracket disposed in a recessed arch portion of the boot. Typically, a projection extends from the sole plate into the bracket. The projection may extend into a slot and may have an enlarged head which nests in a recess in the bracket. The sole plate may be removed by withdrawing the projection from the bracket. Preferably, the bracket is recessed so that when the wearer of the orthotic walks, the bracket does not touch the walking surface. A toe plate may also be used in conjunction with the boot. The toe plate may be mounted to the bracket independently of the sole plate. In one embodiment, the toe plate includes two arms separated by a slot. The two arms embrace a portion of the bracket. Mating ribs and recesses on the bracket and toe plate arms retain the toe plate in the desired position.

    摘要: A method and apparatus is disclosed for sensing when a person is disposed on or arises from a support that flexes or sags when a person is disposed thereon. Such supports include beds, supports for a mattress or a seat, such as a sling-type seat found on wheelchairs. In one embodiment, an assembly is positioned beneath the support and includes a sensor. The sensor indicates when tension on the assembly exceeds a certain amount which is indicative of sagging of the support. The assembly may be adjustable in length to maintain proper tension in the absence of sag. The sensor may be a switch that includes a plunger which operates against the bias of a biasing member which either completes or interrupts an electrical circuit in response to tension placed on the assembly due to sagging of the support. In another embodiment, the assembly may be at least partially elastic. In yet another embodiment, a strain gauge may be employed to detect stretching of the assembly due to sagging of the support. In the method of the invention, a signal received from the sensor may be employed either with or without a processor to activate an alarm or to activate a light or to activate another audible signal or to send a signal over a telephone line. In addition, the signal received may be used to activate or deactivate a brake on a wheelchair.
