Publication number: 20020063918Abstract: An optical switching unit is disclosed which permits switching from faulty components to standby components in optical transmission systems. A component in this connection may be a transmit laser or an optical fiber, for example. The optical switching unit (OSE) according to the invention contains an n×m optical space switch (ORS) whose ports (P1A . . . PNA; P1B . . . PMB) are monitored by photodiodes (M1A, M1B). The photodiodes provide a control unit (SE) with information as to whether and, if so, what signals are arriving at the ports. The control unit (SE) controls the position of the optical switch (ORS) in accordance with program instructions. The switching unit controls itself, i.e., incorporation of a higher-level control center is not necessary. It thus allows very short switching times and has many applications; it is particularly suitable for use in modular optical transmission systems.Type: ApplicationFiled: December 2, 1997Publication date: May 30, 2002Inventors: MANFRED KAISER, FRANK HEHL, RAINER HAUSSER, JURGEN ANHORN

Patent number: 6195581Abstract: The invention is directed to a method of evaluating the signal of an infrared thermometer for measuring human body temperature, in which the infrared thermometer includes a probe adapted to receive thereon a probe cover or protective film sufficiently transparent to infrared radiation, and in which on a measuring operation performed with the probe cover or protective film in “installed” condition the signal is evaluated, so that a measuring operation is performed also when the probe cover or protective film is not installed, with an appropriate allowance being made for the consequently more intensive infrared radiation by different signal evaluation.Type: GrantFiled: May 18, 1998Date of Patent: February 27, 2001Assignee: Braun GmbHInventors: Frank Beerwerth, Klaus Heubach, Manfred Kaiser, Bernhard Kraus, Katja Honnefeller, Heinz Richter, Albrecht Jestädt, Heinz Bültges

Patent number: 6149298Abstract: The invention is directed to a method of computing the radiation temperature of a body from the signals of a radiation and an ambient temperature sensor, and further to a radiation thermometer, in particular a clinical radiation thermometer. In the method of the present invention, computation of the temperature is not using the Stefan Boltzmann law, but rather, a polynomial is used, preferably a third-degree polynomial, which is adjusted to the radiation-optical properties of the thermometer in the relevant wavelength range. The reciprocal value of the sensitivity of the radiation sensor is preferably represented as a polynomial as well. In this manner, the computation of a fourth root or divisions which are otherwise customary are avoided, enabling the necessary computations to be also performed, for example, by a 4-bit microprocessor with great speed.Type: GrantFiled: December 16, 1998Date of Patent: November 21, 2000Assignee: Braun AktiengesellschaftInventors: Bernhard Kraus, Manfred Kaiser

Patent number: 5793188Abstract: The invention is directed to a method of conditioning accumulators in an apparatus operating in the line and the accumulator modes, in which an accumulator discharge/charge cycle is effected at cyclic intervals in which the accumulator is at least nearly completely discharged, wherein a count is made of the number of times the apparatus is used, wherein upon attainment of a predetermined frequency of use a cycle is started when the apparatus is connected to the line, in which cycle the accumulator is first completely discharged through a load and subsequently recharged, and wherein following this discharge/charge cycle a fresh count is made of the number of times the apparatus is used.Type: GrantFiled: September 10, 1996Date of Patent: August 11, 1998Assignee: Braun AktiengesellschaftInventors: Jochen Cimbal, Manfred Kaiser

Patent number: 5499135Abstract: Known optical amplifiers, which are used in a light transmission path to amplify the light signals to be transmitted, have the disadvantage that the semiconductor lasers, used as pump lasers therein, are very sensitive to feedback.According to the invention, the operating current of such pump lasers (4) is modulated at a high frequency, which causes the pump laser to operate in a multi-mode, thereby making it insensitive to feedback. For example, the operating current is DC, on which AC is superimposed.In the event the optical amplifier has two pump lasers, their operating current is also modulated. Both pump lasers are then advantageously alternately switched on and off at a sufficiently high switching frequency, which also prevents reciprocal interference.Type: GrantFiled: October 14, 1994Date of Patent: March 12, 1996Assignees: Alcatel N.V.Inventors: Rolf Heidemann, Thomas Pfeiffer, Manfred Kaiser

Patent number: 5191629Abstract: There is no problem to excite the fundamental mode in a single-mode optical waveguide, if a laser is used whose operating wavelength is above the cutoff wavelength of the guide. However, these lasers are presently very expensive.Especially for the use in the subscriber area, where the relatively short transmission lengths allow to accept a certain amount of attenuation, it is proposed to use an inexpensive laser (6) whose operating wavelength, however, lies below the cutoff wavelength of the coupled optical waveguide (10). The excitation of only the fundamental mode is, according to the invention, possible with such a laser (6). A single-piece metallic module housing (1) is provided in which the laser (6), being moved perpendicularly to the module housing axis (1), is aligned to it by adjusting screws (12). A magnifying optic (9) is provided. The magnification causes a decrease of the angle at which the laser light reaches the face of the optical waveguide (10).Type: GrantFiled: March 21, 1991Date of Patent: March 2, 1993Assignee: Alcatel N.V.Inventor: Manfred Kaiser

Patent number: 4955014Abstract: For short-distance communication systems, particularly for optical-waveguide links in the subscriber area, it is proposed to operate the standard single-mode optical waveguide for long-distance applications, which is optimized for the wavelength range from 1300 nm to 1600 nm, with optical transmitters and optical receivers whose operating wavelengths lie clearly below the cutoff wavelength of the optical waveguide. By means of a suitable stable laser-waveguide coupling, it is ensured that single-mode operation is achieved, which is necessary to transmit digital signals at high bit rates. The increased loss of the optical waveguide at 800 nm can be accepted because of the relatively short length of subscriber lines. Both unidirectional and bidirectional transmission over a single optical waveguide using wavelength-division or modal multiplexing is possible.Type: GrantFiled: October 30, 1987Date of Patent: September 4, 1990Assignee: Alcatel N.V.Inventors: Dieter Kuppers, Klaus Herse, Kate Hiepe-Wohlleben, Manfred Kaiser, Friedemann Mohr, Horst Ohnsorge

Patent number: 4591231Abstract: The variable optical attenuator (1) comprises two spherical lenses (7, 8), one at the input end and one at the output end, between which a bundle of parallel rays is present. A disk (4) having areas (9) with neutral density filters (10) of different attenuation is rotatable through the bundle of rays. A locking mechanism (13, 14, 15) acts on a stub shaft (11) at the disk (4), and its stop positions correspond to the locations of the areas (9). This permits the attenuation of the attenuator (1) to be adjusted in steps.Type: GrantFiled: May 28, 1985Date of Patent: May 27, 1986Assignee: International Standard Electric CorporationInventors: Manfred Kaiser, Wolfgang Stiepek

Patent number: 4417225Abstract: A flat fuse including two plug blades arranged next to one another in the same plane, being spaced from one another. The plug blades are fabricated from stamped sheet metal parts, the plug zones of which extend, in each case, rearwardly in a one piece construction into current-conducting straps. Between the straps, there is arranged a fuse fusion wire which is fastened to the straps. The current-conducting straps and the fusion conductor are surrounded by and enclosed in a plastic casing. The fuse fusion wire includes a copper wire with a silver sheathing, and the current-conducting straps as well as the plug blades are fabricated from brass, in which arrangement at least the current-conducting straps, but preferably also the plug blades, are superficially tinned. The fusion conductor is welded, in each case, to a flat side of the current-conducting straps.Type: GrantFiled: April 8, 1982Date of Patent: November 22, 1983Assignee: Grote & Hartmann GmbH & Co.
