Patent number: 7126144Abstract: The invention relates to a method for the contactless measurement of an object in at least one dimension. An object is scanned in a spatially restricted effective zone of a scanning beam field and the size of the object in terms of the measured dimension is deduced by the detection of one or more interruptions in the scanning beams. The scanning beam field is constructed from a number of directly addressable individual beams. The beam-assisted scanning of the spatially restricted effective zone of the scanning beam field is carried out according to a predefinable pattern of steps, using a non-linear soiling method.Type: GrantFiled: January 7, 2004Date of Patent: October 24, 2006Assignee: Cedes AGInventor: Beat De Coi

Patent number: 7044271Abstract: The described safety mechanism is embodied for elevator systems with an elevator car, which can be displaced in an elevator shaft. The entrances to the elevator shaft and to the elevator car each have at least one sliding door, which is automatically operable by a drive mechanism, preferably arranged on the elevator car. At least one detector device is provided at each sliding door, which is placed in the area of a pinching edge between a sliding door and a door jamb, and/or between two adjoining sliding door panels. Depending on the detected state of the monitored areas, the detector device generates a door release signal, or provides the interruption of the drive mechanism for opening the sliding door. The signals from the detector devices at the sliding doors of the elevator shaft can be received as a function of the position of the elevator car.Type: GrantFiled: December 9, 2002Date of Patent: May 16, 2006Assignee: Cedes AGInventor: Beat De Coi

Patent number: 6124586Abstract: To properly align support elements (17,19), typically support bars or strips of a light curtain formed by a plurality of light beams (21), transmitted between transmitters (13) and receivers (15) on the respective support bars (17,19), a separate alignment light source, typically a laser (29), is provided. The laser (29) projects a light beam (33) to a receiver (35) from one (17) of said bars to the other (19). A counter-directed beam (33') is projected from the other (19) of the bars to the first bar (17). The counter-directed beam (33') spaced from the first direct beam (33), can be generated by a second laser (29'), or by deflecting the received direct beam (33) on or in the second bar (19) by 180.degree. to provide the counter-directed return beam to the first bar (17). This permits rapid alignment of the respective bars, even with respect to five directions of freedom of movement of the respective bars.Type: GrantFiled: June 30, 1998Date of Patent: September 26, 2000Assignee: Cedes AGInventor: Beat De Coi

Patent number: 4896606Abstract: An optical proximity fuze for detonating the associated projectile or missile at a desired distance from a target is extremely sensitive to interfering effects, for example, to rain drops which simulate a target which is non-existent. To minimize the probability of the optical proximity fuze responding in undesired manner to rain drops and thus to reduce the danger of premature detonation of the projectile or missile due to interfering effects, the optical proximity fuze comprises at least two optical transmitters at each of which there is arranged at least one respective optical receiver. The target distance is simultaneously measured by the at least two optical receivers in several chronological measurements. Detonation is only accomplished when the at least two receivers simultaneously respond.Type: GrantFiled: March 20, 1989Date of Patent: January 30, 1990Assignee: Werkzeugmaschinenfabrik Oerlikon-Buhrle AGInventor: Beat De Coi

Patent number: 4873621Abstract: The method of regulation employs a simulation process for at least one state variable of an apparatus to be controlled and regulates the state variable. In the process, a curve of an operating characteristic having its base at an idle state value is traversed up to an operating state value. When re-regulating, the regulation process begins at the current value of the state variable. The value of the regulation variable corresponds to the idle state. This has the advantage of a defined initial point for re-regulation. A regulating device for performing the method of regulation comprises a series circuit containing an input circuit, a regulation circuit with a simulation device for regulating an apparatus as well as a control circuit for possible machines coupled to the apparatus. The simulation device is adjustable according to operating characteristics or apparatus parameters. Another regulating device fulfills the same function while employing a computer and correspondingly modified circuits.Type: GrantFiled: August 13, 1987Date of Patent: October 10, 1989Assignee: Gebrueder Loepfe AGInventors: Beat De Coi, Hans-Peter Keller

Patent number: 4635216Abstract: A length measuring device for thread-like structures, especially textile threads, which are wound onto a cross-wound package or bobbin, possesses a substantially greater accuracy than heretofore known length measuring devices due to a more exact allowance for the geometric and kinematic relationships in the winding device. In particular, the slippage between the cross-wound package or bobbin and the winding drum can be taken into consideration in determining the length of the thread.Type: GrantFiled: March 26, 1984Date of Patent: January 6, 1987Assignee: Loepfe Brothers LimitedInventors: Hansruedi Stutz, Beat De Coi
