Abstract: A bracket (10) adapted to be mounted to a pane of a motor vehicle having a base part (11) and at least one fixation arrangement (12a, 12b, 12c) configured to fixate a camera carrier (35) carrying at least one camera (14) to the bracket (10). Each of the at least one fixation arrangement (12a, 12b, 12c) includes a holder (13a, 13b, 13c) and a spring element (15) configured to exert an elastic locking force on a pin (19) of the camera carrier (35). The spring element (15) forms a base element (17) configured to be held in said holder (13). The spring element (15) comprises a fixation tongue (16) bendably connected to the base element (17) at one end (23) and adapted to exert said elastic locking force on the pin (19) of the camera carrier (35).

Abstract: An impact head includes an arm member moving to a protruding position when a magnetic flux is generated and to a return position when the magnetic flux disappears; an impact member connected to the arm member for protruding when the arm member moves to the protruding position and returning to an original position when the arm member moves to the return position; and an urging member for urging the arm member with a restricted urging force when the magnetic flux is generated and urging the arm member to the return position when the magnetic flux disappears.

Abstract: An impact line printer comprising a print ribbon wound on a pair of spools for traversal in two directions across a plurality of print hammers having tips for impacting the print ribbon to print on a media. A permanent magnet having two pole pieces having pole piece ends in adjacent relationship to the print hammers retains the print hammers until a coil in associated relationship with each pole piece releases the magnetic retention of the hammers. A magnetically permeable extension is longitudinally adjacent each hammer which acts as a magnetic shunt to permit more rapid printing rates and higher impacts. The extensions conduct and shunt magnetic flux from the hammers through the longitudinally adjacent extensions.

Abstract: An ink density closed loop control system for an ink ribbon of an impact printer having a reservoir roller formed of an ink absorbent material with at least one or more channels within the reservoir roller fluidly connected to a pump and ink supply. A transfer roller can contact the reservoir roller for imparting ink to the ink ribbon. A sensor senses the relative amount of ink on the print ribbon and an electrical drive responsive to the sensor drives the pump for a flow of ink to the one or more channels. The sensor can sense ink on different segments of the ribbon and, with two or more channels in the reservoir roller can distribute ink to two or more segments of the reservoir roller depending upon the ink sensed at a particular segment of the ribbon. A further enhancement of this invention provides a multi-viscosity ink to compensate for changes in ambient temperature conditions.
