Patent number: 6511220Abstract: Device and a process for generating a signal dependent upon a liquid film on a surface. The device includes one of a heating arrangement and a cooling arrangement for subjecting a portion of the liquid film to a temperature change, a temperature measuring arrangement for determining the temperature of the liquid film, the temperature measurement arrangement being capable of producing a signal, and a control and evaluation device for controlling one of the heating arrangement and the cooling arrangement and the temperature measuring arrangement. The process includes subjecting a portion of the liquid film to a temperature change using one of a heating and a cooling arrangement, measuring a temperature of the portion using a temperature measuring arrangement, assigning a value which corresponds to a thickness of the liquid film to the temperature change using an evaluation device, and producing a signal.Type: GrantFiled: April 11, 2000Date of Patent: January 28, 2003Assignee: Boschung Mecatronic AGInventors: Marcel Boschung, Jr., Etienne Bornand

Patent number: 5721713Abstract: A watch for indicating the direction of a predetermined locality from a plurality of defined geographic regions. Such watch comprises an arrangement (28, 40) for detecting the direction of terrestrial magnetic north and means (22, 46, 14) for indicating the direction of a predetermined locality from any geographic region whatsoever comprised within a plurality of defined geographic regions. Moreover the watch comprises means (18, 19, 20) operable by a user of the watch in order to furnish a code number to an electronic managing and control unit (22). This number, chosen among a plurality of numbers, forms a code corresponding to the geographic region in which the user is located. With the help of such code number, the electronic unit (22) can determine the mean magnetic azimuth corresponding to the region in which the user is located by means of a memory (26) in which is stored a plurality of mean magnetic azimuths respectively corresponding to said plurality of geographic regions.Type: GrantFiled: December 21, 1995Date of Patent: February 24, 1998Assignee: Asulab S.A.Inventor: Etienne Bornand

Patent number: 5697162Abstract: The arrangement (42) according to the invention is formed by a watch comprising a dial (8) on which is shown a map (14) centered on a given geographic location, Mecca in particular. The arrangement (42) comprises a device (48) for indicating the direction of the terrestrial magnetic north and a device (16) enabling the angular positioning of the map in the general plane of the arrangement (42) corresponding to the plane of the dial (8). The different geographic regions shown on the map (14) are graphically arranged so that any point whatsoever of the contours of such regions substantially shows an angular spread (.OMEGA.), relative to a center of reference (22) corresponding to the above-mentioned given geographic location and to a reference direction (24) equal to the magnetic azimuth of the great circle passing through said point and the reference point (22) augmented by 180.degree..Type: GrantFiled: May 8, 1996Date of Patent: December 16, 1997Assignee: Asulab S.A.Inventors: Etienne Bornand, Jean-Jacques Born

Patent number: 5596551Abstract: Watch comprising an arrangement for detecting the direction of the terrestrial magnetic north formed by a permanent magnet and at least two magnetic sensors (34, 36) arranged for detecting the flux of the magnetic field of the magnet. The watch moreover comprises electronic management and control means serving, as a function of the signals coming from the two sensors, to control indicating means (16) arranged so as to indicate either a selected geographic azimuth or the direction of a predefined locality, in particular Mecca.Type: GrantFiled: November 7, 1995Date of Patent: January 21, 1997Assignee: Asulab S.A.Inventors: Jean-Jacques Born, Etienne Bornand, Rudolf Dinger

Patent number: 5572489Abstract: A universal timepiece (10) having a manually operable outer ring (33) for selecting one of twenty-four time zones, where a display indicates the time of the time zone selected. For this purpose a device for detecting the rotational position of the outer ring (33) is provided which has a special arrangement of permanent magnets (39a-j) in the outer ring (33) and of magnetic switches (27a-h) in the timepiece casing (11, 12) in a specific number as well as evaluating electronics in the timepiece movement (21). The permanent magnets (39a-j) determine the binary statuses of the magnetic switches (27a-h), which are interpreted together as a signal or as a status pattern. The special arrangement of the magnetic switches (27a-h) and the permanent magnets (39a-j) effect for each rotational position an intrinsic status pattern different in each case from the others which permits a clear indication of the selected rotational position of the outer ring (33).Type: GrantFiled: April 5, 1996Date of Patent: November 5, 1996Assignee: Asulab S.A.Inventors: Jean-Jacques Born, Etienne Bornand, Gerard Jaeger, Rene Viennet

Patent number: 5550794Abstract: A watch including an arrangement (14) indicating the terrestrial magnetic north. Such terrestrial magnetic north indicating arrangement is fitted into the watch case (32) in a lateral peripheral region of the horological movement (2). Specifically, the terrestrial magnetic north indicating arrangement comprises a permanent magnet (16) mounted on a shaft (18) and a direction indicator (24) fixed to such shaft. In accordance with three specific embodiments, the watch according to the invention enables, firstly, indication of the north direction, secondly, any direction whatsoever permitting the user to follow a predetermined direction and, thirdly, the direction of Mecca from at least one place on the terrestrial globe where such user is located.Type: GrantFiled: July 20, 1995Date of Patent: August 27, 1996Assignee: Asulab S.A.Inventors: Jean-Jacques Born, Etienne Bornand

Patent number: 5430421Abstract: A reed contactor includes a base plane comprising two distinct conducting zones. Two shafts of the contactor have the form of blades, each of which engages a base plane at the level of one of the conducting zones. One of the beams at least is supported on the base plane by means of a foot on which it is mounted in an overhanging manner. The contactor is formed by process comprising the steps of forming successively on a substrate an alternance of levels of photoresist and of metallization. At each step, the level of upper photoresist is configured to create in its thickness free growth spaces in which metal pins are formed by galvanic growth. The levels of photoresist situated under the last level of metallization play the role of sacrificial layers and allow the formation of suspended metallic structures.Type: GrantFiled: December 14, 1993Date of Patent: July 4, 1995Assignee: Asulab S.A.Inventors: Etienne Bornand, Jean-Luc Simon

Patent number: 5180940Abstract: A radial field electrostatic micromotor produced by photolithographic micromanufacture includes a stator provided with several groups of electrodes angularly offset from one another about an axis of rotation of the micromotor, an electrically conducting rotor at least one arm of which has a counter electrode adapted to cooperate with the stator electrodes to form an air gap therebetween, and a guide ring adapted to drive the rotor in rotation and possibly in translation. The micromotor has a rotor comprising at least one bridging element arranged at least partly above an electrostatic field plane (PCE) of the micromotor. The bridging element constitutes an elevated arm of the rotor having one or more mechanically or electricity functional members adapted to cooperate with one or more complementary members located in or outside the electrostatic field plane and inside or outside the group of stator electrodes.Type: GrantFiled: September 11, 1991Date of Patent: January 19, 1993Assignee: Asulab S.A.Inventors: Lionel Paratte, Etienne Bornand, Georges-Andre Racine
