Patent EP-0256296-A3 (EP)
Title: Apparatus for scanning and reading bar codes
IPC: G06K7/10
Filed: 1987-07-09
Abstract: A preferably hand-held bar code scanner is described in which an invisible laser beam is scanned along a line across the bars of a code in a nominal plane 92 (Fig. 8) in which the bars of said code are disposed; associated with said bar code scanner and preferably integrated with the (hand-held) bar code scanner assembly there is a marker beam system which comprises a source 78 of visible light and associated optics 48 providing a focus of said visible light marker beam along a line 98 generally congruent with the line along which said invisible beam is scanned. For providing said visible light line focus substantially congruent with the line along which the invisible laser beam is scanned, the optics 48 may be an anamorphic or cylindrical lens. The cylindrical lens preferably may serve a double duty in that additionally to providing the visible light line focus of the marker beam system, it may also contribute to suitably shaping the invisible laser beam used for scanning the code bars and/or may also contribute in collecting and focussing the invisible laser beam radiation reflected back from the bar code plane scanned, for detection in the means for reading the bar code.The apparatus disclosed and described thus provides an improved marker beam system which generates a line congruent with the scan path of the invisible laser beam and centered with respect to the length of the scanning path, thus enabling the person handling the bar code reader to reliably and optimally direct the invisible laser scanning beam towards, and into alignment with, the bar code to be read.

Patent EP-0258062-A3 (EP)
IPC: G06F5/16
Filed: 1987-08-27
Abstract: Data buffering apparatus having a synchronous input and 
output capabilities comprises a three stage system which 
synchronizes the incoming data stream with the memory input 
clock, buffers the incoming data stream and provides a 
variable delay for the data. The digital data stream from 
an input device is received by an input synchronizer (11) 
having its input clocked at the clock rate of the input 
device clock and its output clocked at a higher internal 
clock rate. The data is written into two FIFO buffers, a 
master (13) and a slave (15). The master buffer (13) 
controls the read and write addresses of both buffers, so 
that the write address of the buffers advances only when 
valid data is written into the buffers, and the read address 
advances only when data is read out of the buffers. The 
slave buffer (15) can be programmed with an offset in its 
read address, so it operates as a delay buffer. The data is 
read out of the buffers into an output synchronizer (17), 
having its input clocked at the internal clock rate its 
output clocked at the clock rate of the memory control.

Patent EP-0245196-A3 (EP)
Title: Device for data transmission between a fixed part and a mobile part
IPC: H04B5/00
Filed: 1987-04-27
Abstract: An apparatus for bidirectional data transmission includes a predominantly stationary part with a data line connected to cause a phase shift of an osicllator signal for transmission to a predominantly mobile part. AC signal components of the oscillator signal received by the mobile part are formed into square wave pulses and a difference between high and low states of the pulses is indicative of a phase shift. During the high and low states, positive signal edges of a second oscillation frequency are counted and compared to one another so that predetermined difference causes a status change on a data output line in the mobile part.

Abstract: Apparatus for performing and measuring chemical reactions includes a reaction test apparatus having reaction wells wherein reactants are controllably mixed, and exposure apparatus which receives and positions the reaction test apparatus adjacent a photographic film. Each of the reaction wells includes at least two reaction chambers, arranged in a side by side fashion. All but the final reaction chamber have upwardly sloping sides, so that liquid placed in one reaction chamber can flow to the next reaction chamber when the apparatus is tilted. In a preferred embodiment, the reaction wells are supported in a plate that is structurally integral with the wells but separates the wells from each other. The test plate is retained in the exposure apparatus, and liquid is controllably flowed from one reaction chamber to the next by tilting the exposure apparatus. The apparatus of the invention is particularly suited for measuring reactions that produce luminescence of short duration, as the reactants can be conveniently mixed in darkness, while the film is being exposed.

Abstract: Wird ein runder Sensordraht, der durch Bildung einer Spiralfe­
der das Aufrichten eines Sensordrahtes an einer Mine nach dem 
Verlegen bewirken kann, ersetzt durch einen Draht (1) mit 
rechteckigem Querschnitt (7, 8), wobei die größeren Rechteck­
seiten (8) der Querschnittsfläche des Sensordrahtes (1) im we­
sentlichen mit einem Radiusvektor des zylindrischen Trägerkör­

Sensordrahtes im Vergleich zu einem runden Draht beträchtlich 
erhöht, obwohl er immer noch so elastisch bleibt, daß er um die 
Mine ohne Verformung gewickelt werden kann. Eine ähnliche Wir­

nem gleich großen Beidraht verstärkt wird, erreicht, doch ein­
mal ergibt sich eine vorteilhaftere Fertigung mit einem Draht, 
und es wird eine sonst unvermeidliche Vergrößerung der Spiral­
federdicke vermieden, was Einfluß auf den Minendurchmesser ha­
