Title: Method of, and apparatus for detecting access speed for a disc player
IPC: G11B7/09
Filed: 1989-12-07
Abstract: Apparatus for detecting the speed with which a 
light beam emitted by an optical head accesses a target 
record track on an optical disc in which record track 
traverse data indicating track number are recorded 
previously. The traverse data is read and traverse data 
signals indicative of the scanning position of the light 
beam are produced. Deviations in the traverse data signals 
obtained at predetermined time intervals are detected to 
form upper order data bits representing access speed. At 
the same time, tracking error data signals proportionate to 
the deviation of the light beam from a record track on the 
disc are produced and a deviation in the tracking error data 
signals is detected to form the lower data bits of the 
access speed.

Patent EP-0480575-A3 (EP)
Title: Lossless snubber
IPC: H02M3/338
Filed: 1991-09-02
Abstract: A capacitor (156) connected directly across the terminals of the primary inductance (32) of a transformer of a switched mode power supply and a separately wound inductor (54) connected between the primary inductance and the switching power transistor (42) form a lossless snubber circuit. The snubber circuit is more efficient since resistors are not used to dissipate the energy as unwanted heat. The capacitor (156) increases the transistor turn off voltage rise time, thereby reducing radiated emissions. The inductor (54) reduces emissions appreciably by absorbing the ringing that would otherwise occur after the transistor is turned fully off and increases the transistor turn on time to allow reduced emissions. <IMAGE>
Patent EP-0497141-A3 (EP)
Title: Optical isolator
IPC: G02B6/122
Filed: 1992-01-15
Abstract: Optical isolators suppress the retroreflection of light. According to the invention, light coming from a first optical fibre (2) is transmitted on a substrate (1) into a second optical fibre (3) at an acute angle in the region of an optical filter. The first (2) and the second (3) optical fibres do not touch one another. Present in the latter is a quarter-wave plate (7). The light in the first optical fibre (2) is electrically linearly polarised in a plane that is coplanar with the surface of the substrate (1). Since light of this direction of polarisation is very much less attenuated upon passage between the optical fibres (2, 3) than is light which is electrically polarised perpendicular to the surface, the light retroreflected after passing through the quarter-wave plate (7), which light has precisely this direction of polarisation, is almost completely suppressed in the first optical fibre (2). The optical isolator can also be used in an interferometer. <IMAGE>

Title: Automated storage library
IPC: G11B27/10
Filed: 1992-09-30
Abstract: An automated storage library includes four library boxes 1A, 1a, 1B and 
1b, each of which contains four optical disk drives 4 and a robotic 
picker 5. The picker and drives of each box are connected through a 
switch 60 to two library controllers 17A and 17a. Each library 
controller 17 maintains an inventory (70) of all storage media in the 
entire library, but has no disk location inventory. The library 
controllers are not coupled to each other. Each picker 5 has exclusive 
access to a set of storage cells and internal peripheral storage 
devices 4. In addition, a picker controller for each picker maintains 
a disk location inventory (71) for the disks accessible by such picker. 
During a failure condition which prevents one library controller from 
accessing a particular storage medium, the other library controller can 
be signalled to attempt to access such storage medium.
Patent EP-0588040-A3 (EP)
IPC: H01L33/00
Filed: 1993-08-02
Abstract: A light emitting diode has both end faces 
metallized and is mounted on a substrate with the light 
emitting junction perpendicular to the substrate. The 
electrically conductive ends are electrically bonded to 
conductive areas on the substrate by solder or 
conductive adhesive. LED dice can be placed on the 
substrate by temporarily attaching the dice to a tape 
which has been wrapped around a knife edge. The dice 
tilt as the tape wraps around the edge and are picked 
off one at a time by a vacuum collet while temporarily 
supported by a movable finger, and then transferred by 
the vacuum collet to a substrate. A similar method may 
be used for placing semiconductor dice on a substrate 
without the tilting of dice around the edge. In 
another embodiment, an array of LEDs can be assembled 
in windows through a metallized plastic tape which is 
bonded to a foundation with additional metallized 
leads.

Title: High resolution acoustic echo ranging system.
Inventor: PANTON STANLEY
IPC: G01S15/10
Filed: 1993-10-04
Abstract: The uncertainty inherent in high-resolution acoustic pulse-echo distance measuring systems which depend on threshold detection is overcome by transmitting a multi-cycle shot of acoustic energy having a sharply peaked amplitude profile, and locating the peak amplitude of a received echo. The peaked amplitude is achieved by timing the duration of energization of a transducer (8) producing the shot so that energization is terminated before the amplitude of oscillation of the transducer has reached a maximum. This produces a shot which has a definite largest cycle, which should in turn produce an echo having a definite largest cycle. <IMAGE>

Title: Event registration device, especially for homing pigeon sport.
Inventor: MAUL LUDWIG
IPC: G07C1/26
Filed: 1994-06-27
Abstract: A device for registering identification information (19/31), especially for measuring sport times and/or for monitoring and possibly billing in the course of access controls or goods transports, is to be designed as secure against manipulation as possible. For this purpose, a distinction is made between local registration areas in which in each case at least one reader (22) is installed and at least one central processing area which is remote from the former and is operated under special control and in which an analyser (43) is operated. The data transmission between the registration area and the processing area takes place "physically" as it were by means of an operating device (30) which is only connected either to the reader (22) or to the analyser (43). The identification information items (19) picked up coded via the reader (22) and called up from the latter again coded by the operating device (30) are combined with a real-time information item (27) from an autonomous internal clock circuit (28) at the time of their pick-up. This clock circuit is checked at certain intervals by means of the legal time by means of a radio clock and, if necessary, corrected. When the correction value exceeds a particular magnitude, this is additionally logged because the time correction can have its cause in a functional fault in the clock circuit (28) or in an external manipulation of the radio message picked up by the time receiver (29). <IMAGE>
