Patent number: 11218089Abstract: A rotary ultrasonic motor includes an ultrasonic actuator, a driven element, an inner casing member and an outer casing member. A piezoelectric or electrostrictive or magnetostrictive material is arranged between an excitation electrode and at least one general electrode. The ultrasonic actuator is between the inner and outer casing members of a casing, and is directly or indirectly in contact with the element to be driven, so that periodic deformations generated in the ultrasonic actuator by electrical excitation are transferable to the drive element. The ultrasonic actuator is mounted by a retaining device arranged on the casing with at least one retaining section which engages in a recess associated with a respective retaining section.Type: GrantFiled: June 22, 2018Date of Patent: January 4, 2022Assignee: PHYSIK INSTRUMENTE (PI) GMBH & CO. KGInventors: Burhanettin Koc, Thomas Polzer

Patent number: 6971584Abstract: The regulated heating and air conditioning installations normally enable, when controlled, integration of the main factors affecting the comfort of passengers, in particular preventing the windscreen and the other windows from getting clouded. In order to detect incipient mist formation, condensation and moisture sensors generate detection signals, which initiate steps for preventing mist formation when a threshold value is exceeded. Measures are taken for preventing mist formation based on requirements and in a manner adapted to the changing moisture conditions of the glass panes, for example, by using points of intervention stored in a processor. Steps are therefore taken to prevent mist formation, based on moisture variation gradients of the glass panes.Type: GrantFiled: April 26, 2004Date of Patent: December 6, 2005Assignee: Preh Werke GmbH & Co.

Patent number: 6888465Abstract: The invention relates to a sensor unit for detecting the wetting of a window. Signals from the condensation sensor are used to control an air conditioning, heating, and/or ventilation unit. The signals of the rain sensor, on the contrary, are used to control a windshield wiper or washing unit for vehicles. A sensor unit, which comprises two sensors, is placed on the interior of the window. In a preferred variant, both are coupled to a common switchable evaluation unit, so that through mutual evaluation of the two sensors or their signals, both incipient condensation on the interior of a vehicle window and the wetting of the exterior, e.g., by rain, is detected. In an improvement of the invention, both sensors are integrated into a sensor module.Type: GrantFiled: October 28, 2002Date of Patent: May 3, 2005Assignee: Preh-Werke GmbH & Co.

Patent number: 6809530Abstract: As is well known, the influencing variables most important for a sense of comfort are considered during regulation in controlled heating and air conditioning units. Incipient condensation on the windshield or other windows in particular is to be prevented thereby. Sensor modules, inter alia, are employed for this purpose, which have, for example, a capacitative thin-layer sensor. An additional thermopile is provided for determining the window temperature. The present idea eliminates the determination of the window temperature, for which purpose a sensor working capacitatively in the exemplary embodiment is brought directly to the window temperature and a direct thermal coupling of the sensor with the window occurs via a metal plate connected directly to the sensor and a thin adhesive film. The metal plate can thereby form one of the electrodes of the sensor itself or be connected to said electrode in a direct thermal manner. The use of the sensor in the sensor module is a further preferred embodiment.Type: GrantFiled: October 28, 2002Date of Patent: October 26, 2004Assignee: Preh-Werke GmbH & Co., KGInventors: Hans-Michael Schmitt, Juergen Bach, Guenther Oennig, Thomas Polzer, Martin Blaufuss, Rudolf Hartmann

Patent number: 6259571Abstract: An adjustable assembly comprises a base (mount ring 1), an adjustable part (inner ring 3), a lever (tilting lever 5) and a drive (drive element 6). The lever (tilting lever 5) is connected to the base (mount ring 1) and to the adjustable part (inner ring 3) via two elastic solid pivoting joints (7, 8) oriented in parallel. One of the two solid pivoting joints (7) is divided into two pivoting joint parts (7a, 7b), which are arranged such that along their pivoting axis (9) they are offset sideways on either side of the second solid pivoting joint (8).Type: GrantFiled: February 14, 2000Date of Patent: July 10, 2001Assignee: Carl-Zeiss-StiftungInventors: Hubert Holderer, Peter Ruemmer, Michael Trunz, Bernhard Geuppert, Thomas Polzer, Johan Dries, Hugo Timmers, Albert Post
