Granted: 2005-03-29
Abstract: In this method for the computation of travel curves, a door control (11) and a door drive (9) participate in the procedure. A lift cage denoted by (1) displays door blades (2), which are driven by the door drive (9) consisting of a motor (3), a first toothed belt (4), a second toothed belt (5), a drive roller (6), a deflecting roller (7) and an incremental transmitter (8). The motor (3) is supplied with electrical energy by a power unit (12) of the door control (11). The incremental transmitter (8) driven by the deflecting roller (7) stands in connection with a second interface (10) of a microcomputer (13). Algorithms, which are implemented in a travel curve computer (14) of the microcomputer (13), control the door drive (9). Constants needed in the procedure are freely selectable and are communicated to the algorithms by means of a terminal (15). The travel curve computer (14) communicates target values and actual values of the door blade position to a regulation (17), which controls the power unit (12) accordingly.

Title: Method for advancing a guide wire
Inventor: UFLACKER RENAN
IPC: A61B17/22
Filed: 1994-03-15
Granted: 1999-12-14
Abstract: A method of using a hand held vibrating device for transversely vibrating a guide wire in performing angioplasty and atherectomy procedures. The sinusoidal vibrations introduced into the wire by the vibrating device permit the guide wire to be more easily passed through a blood vessel or a stenotic segment of a blood vessel. The guide wire is threaded through a blood vessel until resistance is met. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to sinusoidally vibrate the wire, overcoming the resistance, and facilitating the further advancement of the guide wire.

Title: Flossing equipment and method of operation
Inventor: KOTOWSKI PAUL
IPC: A61C17/16
Filed: 1994-08-03
Granted: 2005-09-06
Abstract: A dental flossing device is characterized by a flossing circuit comprising a floss supply spool and a take-up spool mounted to a housing containing a gear train assembly adapted to rotate the take-up spool in a winding direction. The floss feeds from the supply spool along a pair of prongs forming a forked extension of the handle and is stretched across the forked prongs and appropriately tensioned to be inserted into a user's mouth for flossing. To maintain hygiene, the take-up spool is mounted outside the housing.      In a manually operated embodiment, a manually depressible trigger projecting from the housing is operable to rotate the take-up spool with reverse rotation thereof being prevented with a ratchet mechanism. Release of the manually depressible trigger reversely rotates the supply spool through a short arcuate interval to remove slack and then locks the supply spool against unwinding rotation through gear teeth. In a preferred manually operated embodiment, first and second ratchet mechanisms are utilized to prevent reverse rotation of the supply and take-up spools while sufficiently tensioning the floss circuit. In other embodiments, the housing may be formed for mounting the flossing device as an attachment to a hand-held motorized toothbrush handle equipped with a motor from which projects an output shaft. Depending upon the model, the gear train assembly may be modified to convert longitudinal stroking motion of the shaft or oscillatory motion into uni-directional rotating motion to rotate the take-up spool in one direction only.
