Abstract: A force sensor system for measuring forces that are transferred from film strips or sheet metal strips to a measuring roll during rolling in roll stands can be inserted into a cylindrical hole of a measuring roll under preload. The force sensor system includes a first force sensor and a preloading device for creating a preload on the first force sensor, so that the first force sensor can determine a force acting radially on the measuring roll. The first force sensor has a high sensitivity, which corresponds to the required measurement sensitivity of the contact force of the film strip or sheet metal strip. The force sensor system includes a second force sensor, which also can be placed under preload by means of the preloading device. The second force sensor is a statically measuring force sensor.

Abstract: A rearview mirror incorporates the use of electrochromic mirror glass capable of dimming via electronic controls. The electrochromic mirror glass dims when glare from vehicle driving aft of the motor vehicle impinge on the rearview mirror. The rearview mirror includes a control circuit with a single sensor. The sensor receives glare from aft and ambient light forward the motor vehicle. A light conductor guides light from the two directions. A sensor receives the light from the two directions and is able to discern between the glare light and the ambient light, by filtering the light received from each direction based on color. One color is received from one location and not from the other. The sensor is sensitive to wavelengths and can identify the magnitude of flux received in each color. This allows the interior rearview mirror to identify situations that are appropriate for dimming the electrochromic mirror glass.

Abstract: An electromechanical joining module for applying a linear force to a joining element, includes a stator, which represents the stationary part of the joining module, a tappet, which can be linearly extended out of the stator and which has an outer tappet end, and a force transducer for detecting forces that are applied to the joining element during the operation of the tappet end. The force transducer is attached in the area of the tappet end and has sensor electronics for wirelessly transmitting measurement data by means of near-field and far-field telemetry.

Abstract: A rearview mirror reflects ambient light and dims when light from headlights of a following motor vehicle is detected. Electrochromic mirror glass is fixedly secured to a frame within an opening. A sensor is fixedly secured to a housing for sensing ambient light and focused or glare light directed toward the rearview mirror. A light guide is disposed between the housing and the sensor for directing the ambient light and glare light outside the housing toward the sensor. The rearview mirror also includes a switching device for periodically disrupting the transmission of the light to identify a presence of the glare light, such that the sensor creates a dimming signal upon the identification of the presence of the glare light to dim the electrochromic mirror glass. The use of the switching device minimizes the number of sensors required by using the same sensor for measuring ambient light and glare light.

Abstract: Oscillating or vibrating components, especially inside rearview mirrors, are provided in motor vehicles. In order to avoid undesirable vibrations of the inside rearview mirror, the mirror housing (3) is reinforced or complex measures need to be taken to secure the mirror housing (3) to the vehicle. The aim of the invention is to at least significantly reduce the amount of vibrations for various components of motor vehicles by using granulate particles (9) as vibration suppression elements which are placed in a recess. The granulate particles (9) make it possible to suppress and attenuate vibrations in a simple manner. The vibration suppressors are advantageously used in inside rearview mirrors in motor vehicles.

Abstract: The hairstyling agent in gel form contains a combination of at least one gel former, more than two percent by weight of at least one UV filter and at least one hair-fixing polymer. The hairstyling gel preferably is in optically clear form and can simultaneously have hair fixing action, light protective action for the skin and light protective action for the hair or dyed hair colors. Preferred UV filters have both a benzimidazole group and a sulfonic acid group.

Abstract: A control circuit having particular application in dimming an EC (Electrochromic) mirror glass of a rearview mirror of a motor vehicle. Light flux from headlight glare of vehicles traveling behind is received by one conductor and filtered whereas light flux from the ambient light is received by a second conductor and filtered in a way that complements the first filtering. This allows a single sensor to be used to sense both the ambient light and the glare light which enables simpler control of the dimming function.
