Title: Controlling quality of workpieces by taking successive images of them
Inventor: HENNING ARMIN DIPL ING
IPC: B07C5/342
Filed: 1996-08-20
Abstract: The method includes the taking of successive images of workpieces to be controlled using an electronic image taking unit. The workpieces are firstly taken individually from a storage, in a specified alignment under the influence of gravity successively in a vertical in a vertical recording stretch. Each workpiece is guided in free fall through the recording range of the electronic image takin unit. Also in a selected alignment to the recording axis of the image takin unit, a short time image recording of the workpiece is taken and supplied to an electronic evaluation unit. The workpieces then, depending on a good or a rejection signal produced by the evaluation unit, are led from the dropping stage in to a further conducting track for the workpieces deemed as good or a further conducting track for the rejected workpieces.

Patent DE-19744180-A1 (DE)
Inventor: SCHNACK MANFRED DIPL ING
IPC: H05B6/80
Filed: 1997-10-07
Abstract: The invention relates to a device for heating up meals, preferably in an aircraft, especially for a large number of passengers in a large-capacity aircraft. The meals are arranged on trays which serve as meal supports and which can be served to passengers and then guided through a heating oven together with said trays in order to heat up the hot meals to a predetermined serving temperature of preferably 50 to 55 DEG  C. The heating oven provided is a gyrotron oven with individually guided surface radiation for radiating the meals with high-frequency millimetre waves. The surface radiation is homogeneous and directed and is dependent on the arrangement of the hot meals on the tray. This enables a number of hot meals to be heated up to a suitable temperature for the mouth immediately before serving and ensures that all of the passengers in a large-capacity aircraft can be served optimally and at approximately the same time. A computer regulates the surface radiation and the heating of the hot meals as the meals pass through the gyrotron oven on the trays.

Title: Method of preventing collision of vehicle with obstruction
Inventor: FRIEDERICH MICHAEL
IPC: G01S13/931
Filed: 1998-02-18
Abstract: The method involves detecting the distance between the vehicle and obstruction, the relative speeds and the speed and acceleration/deceleration of the vehicle and triggering a collision warning and/or braking process accordingly.
