Patent SE-0003110-D0 (SE)
Inventor: PETTERSON BO
IPC: G01D5/241
Filed: 2000-09-04
Abstract: An angle transducer comprising a first disk, the rotor, with circularly arranged and radially directed receiver electrodes and a second disk, the stator, equipped with circularly arranged and radially directed transmitter electrodes arranged at the same radius as the receiver electrodes and with a fixed separation between the receiver and transmitter electrodes, whereby the disks are arranged coaxially and rotatable relative to each other, and the disks are further separated by a thin air-gap. The transmitter electrodes are each supplied with an alternating voltage with different phases for neighboring electrodes, whereby the number of supply phases, phi, is greater than two, and the separation of the transmitter electrodes=the separation of receiver electrodes/phi. The transmitter electrodes of the stator are geometrically arranged such that errors in their geometry relative to the geometry of the receiver electrodes produce equal but opposite error signal in the receiver electrodes of the rotor.

Abstract: The present invention relates to an optoelectronic transmitter for converting an electrical information signal (Se) into an optical signal (So) that represents the same information. The proposed optoelectronic transmitter includes a multi-section optoelectronic modulator. The light and electrical fields thus interact over multiple modulator sections (421a - 421c) of a continuous waveguide (421). A particular drive cirucit (423a a 423c) delivers a phase-aligned and amplified electrical signal (S'e, S''e;    S'''e) to each modulator section (421a - 421c9. For a given extinction ration of the modulated optical signal (So), a signal voltage swing can thereby be used, which is substantially lower than according to any known single- or multi-section modulator structure. This, in turn, makes the proposed optoelectonic transmitter well suited for sending data at high-speed bitrates.

Abstract: A submarine cable with optical fibers which prevents damage to the fibers due to water pressure without the use of an external armor. The cable has a central core with a strand which provides the cable tensile strength and which is surrounded and contacted by a layer of plastic material having helical grooves which receive the optical fibers which may have a protective covering. The layer of plastic material is surrounded by a thin metal sheath which, in turn, is closely surrounded by a layer of plastic material. The grooves and any spaces radially inwardly of the sheath, such as the spaces between the wires of the strands, are filled with a practically incompressible fluid, such as a grease or jelly. If the optical fiber protective layer is a tube loosely receiving the optical fiber, or optical fibers, the space within the tube not filled by optical fibers is filled with a substantially incompressible fluid. A further layer of plastic material may be interposed between the metal sheath and the plastic material layer of the core and may at least partially extend into the grooves.

Abstract: A vehicle torque transfer gear assembly unit for driving four wheels of a vehicle in which both the rear and front output shafts of the unit are capable of straight line connected relation with the rear and front drive shafts of the vehicle thereby eliminating the need for complex compound angled connecting means. The preferred embodiment exemplifying the invention is a five gear assembly of two input gears and three output gears selectively connectable for two wheel or four wheel high speed operation, or four wheel low speed operation beside a neutral mode. The rear output shaft is aligned in a straight line with the rear drive shaft extending downwardly toward the rear wheel differential while the front output shaft extends downwardly in the opposite direction to the front drive shaft toward the front wheel differential. The cross axised relation of the output shafts is effected by utilization of a frustum shaped front output gear having helical cut teeth matched to an intermediate gear on an axis parallel to the rear output shaft. As another embodiment, the front output shaft angle is produced by addition of an angular association of the intermediate shaft and gears thereon relative to the rear output gear and an angular association of the front output shaft and gear relative thereto by use of frustum shaped front output gear with helical cut gear teeth matched to the desired angle.

Abstract: A wheel device is pivotably mounted on a bottom surface 3 of a piece of furniture 4 or the like and has two tilted wheels 2 which at their periphery are in roller contact with a floor 5. The wheels 2 are rotatably mounted on a holder 9, which in turn is pivotably and eccentrically mounted about the mounting axis 10 of the device. The fact that the rotational axis 14 of the respective wheel 2 forms an angle v with the mounting axis 10 produces a very good load-withstanding ability. The wheel device 1 can therefore be pivoted in its entirety about the mounting axis 10 whilst the wheels 2 roll against the floor 5 as they rotate about their rotational axes 14. Owing to this specific arrangement, the wheel device 1 acquires a very low structural height h compared with previously known wheel constructions of similar type. With an angle v of 30 DEGREE and a wheel radius R of 10 mm, the structural height h is only ca. 16 mm. <IMAGE>
