Abstract: A free standing, height adjustable ballet bar exercise device is provided. The device comprises a pair of legs, telescoping support arms pivotally attached to the legs and supporting a horizontal ballet bar disposed between the support arms, a lower cross bar connecting the legs intermediate their ends, an upper cross bar connecting the support arms, a backboard pivotally attached to the upper cross bar and releasably attached to the lower cross bar, and a floor board hingedly attached to the bottom edge of the backboard and adapted to lay flat on a floor to support the weight of the user. Preferably the backboard and floor board are covered by soft mats.

Abstract: The design of a thermistor maximizes the temperature sensitive effects of the semiconductive inks while minimizing or eliminating the force sensitive effects. The design provides for an integrated force and temperature sensor having reduced costs, improved sensitivity and reproducibility, and greater reliability. A thick film thermistor has (a) a pair of shaped electrical conductors deposited on a first support substrate; (b) a temperature sensitive ink layer deposited over the pair of electrical conductors so that the ink layer is coextensive with the pair of electrical conductors; and (c) a second support substrate bonded to the first support substrate.

Abstract: A force sensor employing a segmental electrode construction, with a portion of one of its pair of electrodes being printed on a first backing sheet and another portion of the one electrode being printed on a second sheet. When they are juxtaposed they form a continuous electrode. The other of the pair of electrodes is also formed on the first backing sheet and cooperates with the first electrode to indicate when a load is applied to a zone in which the pair of electrodes overlie one another.
