Abstract: An electronically operated card such as a debit or credit card, having internal data handling capabilities. The card may include in addition to a conventional magnetic strip, a data processor, a display, an on-off switch which may be a biometric switch, a power supply which may comprise a capacitor with or without a photovoltaic cell, and data busses enabling communication with external devices. The card may be used in combination with an external docking station which may be communicably connected to personal computers and to communications devices such as cellular telephones. The data processor may have programming enabling the card to perform functions which may be conventionally performed at card swiping terminals, automatic teller machines, and the like, such as balance reporting, funds transfers, purchase authorizations, displaying notices from such terminals and machines, and the like.

Abstract: Glasses such as bifocals, which have refractive lenses which are rotatable at least between two positions. A manual control rotates the lenses such that if bifocal, the relatively small, high magnification zone of each lens can be moved to a high position opposed to the usual low position of fixed bifocals. The user is spared the necessity of holding the head at an awkward posture when viewing overhead objects.

Abstract: A signaling system includes a rotatable arm connected to a dock. One end of the arm has secured thereto two signaling paddles of distinct visual indicia. The other end of the arm is biased against the underside of a lip plate of a dock loader. As the lip plate is pivoted relative to the dock, the arm is rotated, thus rotating the signaling paddles attached thereto.

Abstract: A microwave clothes dryer, including a housing around a rotating tumbler, a pivoted door on a front of the housing having a microwave heater on its inner side, and the tumbler being changeable in shape as it rotates.
