Patent DE-4216073-A1 (DE)
Inventor: NAKATA MASAHIRO
IPC: G02B7/36
Filed: 1992-05-15
Abstract: An automatically focussing camera moves a lens to its in focus position. The focus state is repeatedly checked and the lens moved if necessary (Fig 2, 3). If the ions has to be moved three times, the camera's subject is judged to be moving and the camera switches to predictive focussing (Fig 4, 5), in which the subject's speed is calculated on the basis of successive measurements of the amount of deforms, and from this, the position to which the lens must be moved and its speed thereafter are determined; the speed measurement is repeated to compensate for changes in subject speed. If the subject stops, predictive autofocus ceases. Once satisfactory tracking has been established, the lens is advanced faster and then stopped so as to allow for mirror and photometering operation (Fig 6, 7) before exposure when the subject has "caught up". Alternatively (Fig 18, 19) the lens may continue to be moved at a speed corresponding to the subject speed throughout. Backlash can be compensated for when the direction of movement of the lens is changed. Defocus amount is calculated from the phase difference of two images both obtained via the camera lens. If contrast is low, the minimum of the 'present' and 'previous' defocus amounts is used. A contrasting pattern may be projected onto the subject, in which case the predictive focussing is disabled.

Patent DE-4218769-A1 (DE)
Inventor: BAUER HARALD
IPC: G06F7/544
Filed: 1992-06-06
Abstract: In digital signal processing it is often necessary to establish the sum of a chain of products, and to do so as fast as possible. Known signal processors often use two separate data buses for a parallel feed of the values to be multiplied, assuming that these values come from different sources, for example from different memories, and since a product of two binary numbers has double the number of places, an adder with double word length is therefore used. To reduce this substantial outlay with only slight reduction in processing speed, the invention proposes to use an adder with just single word length and to process the most and least significant bits of the product in two successive clock phases such that the values to be multiplied can be simultaneously fed in succession.
Patent DE-4219355-A1 (DE)

Patent DE-4219915-A1 (DE)
Inventor: DANNENHAUS PETER
IPC: B29C45/17
Filed: 1992-06-17
Abstract: The process relates to the manufacture of injection moulded articles from thermoplastics, in which a plastic melt is forced into a mould by means of a gas injected at high pressure and the plastic is cooled by means of a cool medium. To reduce the amounts of gas necessary for cooling and to reduce the manufacturing time, it is proposed, during the solidification phase of the plastic melt, to introduce a cold gas under controlled pressure change into the mould interior. In this process, nitrogen is advantageously used as cold gas and as the gas injected into the plastic melt.

Patent DE-4325137-A1 (DE)
Title: Process for actuating closure mechanisms with the aid of identification means
Inventor: RECKERMANN MICHAEL
IPC: G07C9/00
Filed: 1993-07-27
Abstract: The process serves for the actuation of <a> electronically locked closure mechanisms of a closure system with the aid of <b> identification means. Each closure mechanism exhibits a microcomputer for communication with the identification means. Each identification means exhibits an identification number, which gives authorisation for the actuation of at least one of the <a> closure mechanisms, and at least one random number. If the microcomputer in the closure mechanism recognises the identification means, via the identification number thereof, as being authorised, it compares the random number of said identification means with the random number which has been stored in it for said identification number. It is only when the two random numbers also correspond that the microcomputer releases the closure mechanism. At the same time, it generates a new random number, which is stored in its closure mechanism and in the identification means.
