Patent number: 4967081Abstract: An infrared detector has two infrared detector elements contained in a housing, the housing having a window which is transmissive for infrared radiation, and further electrical components interconnected with the detector elements are also contained in the housing. The housing is formed of a shaped plastic part in which a shaped sheet metal element and the electrical components are embedded. The shaped sheet metal component electrically connects the electrical components, and is provided with outward projections serving as the exterior terminal pins. The shaped sheet metal component has angled regions which are bent to surround at least a portion of the electrical components for shielding thereof.Type: GrantFiled: June 15, 1989Date of Patent: October 30, 1990Assignee: Heimann GmbHInventors: Reiner Quad, Udo Ringelstein, Fred Plotz, Gerhard Knaup

Patent number: 4752769Abstract: The invention is directed to an infrared motion alarm characterized by an infrared detector and an optical arrangement before the detector in the radiation direction for focussing the infrared radiation onto the detector. The optical arrangement is formed by a mirror arrangement and by a lens arrangement with the mirrors being on different levels so the different beam paths are being detected to prevent an intruder from crawling under the infrared detection beam paths.Type: GrantFiled: September 2, 1986Date of Patent: June 21, 1988Assignee: Heimann GmbHInventors: Gerhard Knaup, Fred Plotz, Norbert Schaaf
