Patent number: 6497043Abstract: A shaving device with one or more shaving blades. Sensors are attached to (or near) the blades which produce a shaving signal. A processor or intelligent analysis unit then receives the shaving signal and determines what shaving changes should be made. An audible indicator is coupled to the processor to inform the user of the shaving changes needed. The audible indicator is a speech playback unit, or it produces an audible sound or tone. In the alternative, a visual indicator can be used, such as a liquid crystal (LCD) or a light emitting diode (LED) display, which informs the user of the shaving changes needed.Type: GrantFiled: October 13, 2000Date of Patent: December 24, 2002Assignee: Sarcos, L.C.Inventor: Stephen C. Jacobsen

Patent number: 6170162Abstract: A rotary displacement measuring apparatus includes an axle whose rotary displacement is to be determined, with the axle being mounted to rotate about its long axis. An emitter disk is mounted on the axle to define a plurality of concentric tracks circumscribing the axle to rotate as the axle rotates, with each of the tracks being segmented to define a plurality of spaced-apart, conductive sections for producing electric fields when energized. Also included is a voltage source for energizing the conductive sections. A detector is disposed adjacent to the tracks of the emitter disk and includes a plurality of sensors, each positioned adjacent a respective track to detect the electric fields of the respective track as the axle and tracks are rotated. The detector produces signals representing the detection of the electric fields as the emitter disk is rotated, and these signals provide an indication of the rotary displacement of the tracks and thus of the axle.Type: GrantFiled: May 27, 1999Date of Patent: January 9, 2001Assignee: Sarcos, L.C.Inventors: Stephen C.

Patent number: 6066361Abstract: A method of coating a surface of a filament. In particular, the invention rotates a member (13) about a first axis (54), which will rotate a tubular member (16), which is rotatably coupled to the rotating member at an angle to the first axis, through a plane and about a longitudinal axis (56) of the tubular member that is co-planer to the plane. This is done to assist in the depositing of a uniform material onto the filament that extends through the tubular member and through a deposition area (40). It is important for the method to maintain the deposition area at an intersection of the first axis, longitudinal axis and plane, while the filament is being rotated in step. The method provides for adjusting the deposition area to expose a different length of the filament to the deposition of material thereon.Type: GrantFiled: July 29, 1999Date of Patent: May 23, 2000Assignee: Sarcos L.C.Inventors: Stephen C.

Patent number: 6063200Abstract: A fixture apparatus for material deposition or processing on a long, flexible, nonplanar, filamentary substrate has a tubular member for holding the filamentary substrate rotatably disposed on a base. An opening is formed in the tubular member through which material is deposited on the surface of the filamentary substrate. Moveable tubes are each slidingly disposed in the tubular member on either side of the opening. The tubes and/or the tubular member hold the filamentary substrate on both sides of a deposition area on the substrate to maintain the straight configuration of the long, flexible, filamentary substrate. The tubes and/or tubular member also physically masks the filamentary substrate to prevent material deposition outside the deposition area on the substrate. The base has a circular path and a rotating member. A wheel is coupled to one side of the tubular member and is rotatably disposed on the circular path of the base.Type: GrantFiled: February 10, 1998Date of Patent: May 16, 2000Assignee: Sarcos L.C.Inventors: Stephen C.

Patent number: 5980496Abstract: The method for automatic dosing of drugs utilizes a delivery device which may be administered to an animal. The delivery device is configured to have one or more compartments or reservoirs, each containing at least one drug so that a plurality of doses of the drug(s) are held within the device. In accordance with the present invention, the delivery device selectively releases doses of the drug(s) to provide an efficacious dosing pattern. One primary function of the present invention is to release two or more pesticides in such a pattern that parasites are effectively controlled while preventing the development of tolerance to the drugs within the parasites. Preferably, the delivery device is programmable to effectuate the release of the drug(s) at a desired time to maintain efficacious levels of the drug while minimizing the amount of drug which must be used.Type: GrantFiled: December 11, 1997Date of Patent: November 9, 1999Assignee: Sarcos L.C.Inventors: Stephen C.
