Patent DE-3340705-A1 (DE)
Title: High-speed pattern recognition apparatus
Inventor: SACKS JACK
IPC: G06K9/32
Filed: 1983-11-10
Abstract: The invention relates to an apparatus and a method for storing a reference scene and a search scene in separate, addressable memories. The reference scene is addressed along a scanning line at a specific angle, which produces the impression that the reference memory has been rotated. The search-region information is processed using stored reference information in order to obtain a numerical value which represents the number of matches for a search position at a large number of selected angles. The processed numerical value is aggregated, and the search is ended when the processed numerical value exceeds a given threshold value. The X- and Y-coordinates for the best search are determined by estimating the highest aggregated numerical value. The angular alignment of the search area is fixed by addressing each scanning line read-out value of the stored reference area in small angles, this read-out value being processed using the memory read-out value, a numerical value for a selected number of scanning angles being aggregated and the angular position having the maximum numerical value being determined as a measure of the alignment angle of the search area. <IMAGE>

Title: Precision firing point
Inventor: IMMENDORF KARL M DIPL ING
IPC: G07F17/38
Filed: 1984-08-20
Abstract: An electromechanical firing point is designed as an automatic competition device such that it   I. supplies unambiguous firing results which are formed in the apparatus and are not subject to unreliable visual evaluation. II. Allows the degree of difficulty of the apparatus to be matched in a simple manner to the average skill level of the user. I. Is achieved by firing at double-sided practice targets which have the known ring symbols on the side at which the person firing aims while, on the rear side, annular conductor track segments having the same centre are briefly scanned - during firing - by a contact die whose axis is firmly connected to the rifle.   The charge-dependent pulses are supplied to a computing mechanism, are converted, displayed and stored, and the mean hit rate is continuously calculated at the same time. If the person firing wants confirmation of his performance, he is given a paper practice target, which is perforated by an electromechanical stamp and has only unambiguous results - hits between the target value rings. II. The level of difficulty is matched to the mean skill level of the person playing by varying the diameter of the contact die, either manually or automatically within the apparatus itself. a

Title: Device for the contact-free measurement of the air-gap width between the rotor and stator of electrical machines
Inventor: ZEGGERT WOLFGANG DR ING
IPC: G01B11/14
Filed: 1984-09-28
Abstract: The described device determines the air-gap width by measuring the separation of light marks which a light-mark transmitter produces on the rotor surface and stator surface. The arrangement of an objective and of an optoelectronic sensor in the axial extension of the air gap to be measured is used as a distance converter. In this case, the rotor and stator light marks are imaged on the optoelectronic sensor. The latter converts the brightness distribution imaged on it into a time-dependent electrical signal which is proportional to said distribution. The evaluation of this sensor signal in an electronic circuit provides an electrical variable which is proportional to the light mark separation, and hence to the air-gap width.

Title: Hydropneumatic suspension with load-dependent damping
Inventor: BECK HUBERT
IPC: B60G17/08
Filed: 1985-05-31
Abstract: A hydropneumatic suspension was to be designed so that even with a fitting of the piston rod on the body side a simple and reliable level control is created, which for improvement of the ride comfort ensures an automatic increase of the vehicle damping during loading and a reduction of the vehicle damping when the vehicle is unloaded. In order to solve this problem a telescopic spring cylinder is connected on the one hand to a pressure medium pump and a control element in order to control a reference level and on the other to an accumulator. At the same time the valve of the damping piston serving for the tensile damping is also acted upon directly or indirectly by a gas cushion arranged in a sealed chamber. In this way influencing of this valve is obtained by an automatic, load-dependent damping adjustment.

Title: Screening wheel for beet-harvesting machines
Inventor: WESTPHAL HERBERT ING GRAD
IPC: A01D19/14
Filed: 1985-07-08
Abstract: The invention relates to a screening wheel for beet-harvesting machines, with tines mounted at one end and arranged on a rotating hub driven about an approximately vertical axis. According to the invention, tines which are movable, that is to say are designed as vibrating tines (2) or jogging tines (3, 4), are provided between rigid tines (21). In a version with vibrating tines (2), the vibration of the tines is obtained by the falling down of beet conveyed upwards at a relatively large distance above the ground by means of a lifting device (preferably lifting wheels (6)). In this version, the screening wheel (1) runs forwards and conveys round and the beet falls into the rear screening-wheelhalves so that an especially long conveying and cleaning path is obtained on the screening wheel (1). In a version with jogging tines, there is mounted on each fixed tine (21) a bearing body (25) which is pivotable through a limited angle about its longitudinal axis and carries a jogging tine (3) and which, during each revolution of the screening wheel, has a jogging boss running onto at least one actuating element (24) fixed to the frame and serving for pivoting the tine. Jogging tines (4) which are pivotable about an axis extending transversely to the tine axis can also be provided. <IMAGE>

Title: Suspension of a non-driven vehicle rear axle
Inventor: SCHMIRLER GUENTER DIPL ING
IPC: B60G7/04
Filed: 1985-08-09
Abstract: The invention relates to the suspension of a non-driven vehicle rear axle by dint of at least one parabolic single-leaf spring suspended at both ends in the longitudinal direction/direction of travel, which towards the compression side is elastically limited in its spring travel by a support element and at its rear end in the direction of travel is suspended in a spring shackle for constraint-free length adjustment. The spring in such a case serves both as a spring- and as a wheel-suspension element, especially also in the case of a fracture of the spring. The object of the invention is to ensure that the spring occurs not in the front spring arm, that is between the front end of the single-leaf spring in the direction of travel and the vehicle rear axle, but in the rear spring arm opposite. In such a case the front spring arm can act satisfactorily in tension as a trailing arm for the vehicle rear axle. This is achieved in that between the front end of the single-leaf spring in the direction of travel and the vehicle rear axle, that is opposite the front spring arm, an additional buffer is arranged in the suspension travel. The additional buffer is preferably arranged somewhat opposite the longitudinal centre of the front spring arm.
