Patent EP-0785548-A2 (EP)
Inventor: CHAPMAN DALE
IPC: G11B7/00
Filed: 1996-11-22
Abstract: 1A baseline correction circuit (272) (BCC) that compensates for the offset present on a PWM signal in an optical readback system when associated transients first appear in the PWM signal, and then compensates for the decay in the PWM signal so that significant baseline variations are minimized. The BCC includes a BCC switch (278) coupled to switch the PWM signal responsive to a control unit (160) and a low pass filter (276) coupled through the BCC switch to receive the PWM signal. The low pass filter includes a capacitor coupled between the PWM signal and a ground reference, which stores the voltage of the baseline variation. A difference amplifier is connected to receive the low pass filtered output and also the PWM signal, and to provide a difference signal responsive to the difference between these two signals. The resultant signal is a high-pass filtered version of the PWM signal originally supplied to the BCC. A control unit monitors and controls disk operations, and supplies a transient event signal indicative of a predetermined upcoming baseline variation in the PWM signal, which turns on the BCC switch. At a predetermined time after the transient event has occurred and the baseline voltage has been stored on the capacitor in the low pass filter, the control unit switches off the BCC switch, and the signal from the low pass filter decays at a rate approximately following the input PWM signal into the BCC. Advantageously, such a baseline correction circuit can minimize the dynamic range requirements necessary to handle baseline variations and thereby provide a lower cost readback system that is particularly useful for PWM readback circuits in an optical readback and recording system. Compatibility with PPM systems is possible if the baseline correction circuit is left on so that it operates as a high pass filter and therefore, the readback system described herein can be used to read both PPM disks and PWM disks.

Abstract: The system for controlling function selectors (1) essentially envisages that an emitter (3) and a receiver (4) of an infrared signal (Se) be housed in a single body (6) defining a single selector (1), and that they be separate and shielded; the signal (Se) is detected by the receiver (4) when a reflective surface (5) is moved towards the emitter (3) and receiver (4) within a threshold distance (Ds); a comparator (7) is also envisaged, for an output signal (Su) from the receiver (4), designed to send a relative selection signal (Ss) to a microprocessor (2) if the value of the output signal (Su) is equal to or greater than a reference signal (Sr) which may be preset on the comparator (7), and if the preset dwell time (Ts) of the output signal (Su) is equal to a reference time (Tr); finally, there is also a discriminator (8) for the selection signal (Ss) from the comparator (7) which inhibits the selection signal (Ss) towards the microprocessor (2) if there are at least two simultaneous selection signals (Ss) from different selectors (1).

Abstract: A une première extrémité d'un ensemble prisme de fibres optiques, des terminaisons de fibres viennent en contact avec une surface présentant des reliefs telle qu'un doigt (stabilisé par une poignée). Dans une région où le diamètre des fibres est principalement constant par rapport à une position longitudinale, la lumière pénètre dans le prisme, traverse les fibres et s'introduit dans les fibres individuelles par leurs parois latérales, éclairant les terminaisons. Afin de permettre un éclairage transversal de l'ensemble, la valeur d'ouverture des fibres optiques (NA) est petite et ne dépasse pas de préférence 1/2. Selon les détails notamment des empreintes digitales, des fractions de lumière passent le long des fibres. A la seconde extrémité de l'ensemble, un détecteur réagit à un groupe de signaux électriques en fonction du relief de la surface. Les signaux sont traités pour identifier les doigts ou autres et sont envoyés à un contrôle d'accès d'une arme individuelle, d'autres équipements, installations, données ou d'un service financier. Des versions à zone claire et sombre FTIR ('Frustrated total internal reflection') présentent divers avantages. Dans l'utilisation de petits détecteurs, bon marché - et/ou des versions à miroirs internes qui éclairent directement le doigt - l'ensemble comporte un élément séparé tel qu'un cône de fibres optiques à grande valeur d'ouverture (NA) à absorption hors paroi ou cône à substance 'EMA' (aucune lumière entrante ne le traverse). Pour une arme, un module monobloc antidérivation (raccordé à un connecteur électrique d'arme et ne devant jamais être déconnecté) bloque une partie du contrôle d'accès et des systèmes de mise à feu. Les balles sont tirées uniquement lorsqu'un signal spécial est émis par le module.

Abstract: Systems and methods for automatically increasing server performance
in a communications network are presented. Individual servers are provided
with the capability to automatically reject incoming communications when a
performance evaluation by the receiving server indicates that performance will
be significantly, negatively affected by processing the new communication
(i.e., the server will begin to be overloaded and performance will suffer). In
rejecting the incoming communication, the server sends the received packet
back to the sending server along with a rejected message and a secondary
transmission address (i.e., an alternate end-server). The initial sending server
then re-transmits the communication using the secondary address as the
primary address. The techniques of the present invention are particularly
applicable to servers used to provide toll free service -- where the dialed
number is not the actual destination number. Other applications of the present
invention are also disclosed.

a substrate holder disposed in the vacuum housing for
holding a substrate thereon, and a composite sputtering
cathode assembly disposed in the vacuum housing. The composite
sputtering cathode assembly has a plurality of targets
and a plurality of shields each disposed between adjacent
ones of the targets. The targets are disposed in
confronting relation to the substrate held on the
substrate holder. Those sputtering particles expelled
from the targets which are directed obliquely to the substrate
hit the shields and do not reach the substrate.
Only those sputtering particles which are directed substantially
perpendicularly to the substrate are applied to
the substrate. Minute holes in the substrate which have a
high aspect ratio are filled with a thin film with a good
coverage. The distribution of film thicknesses on the
substrate is made uniform when the substrate and the targets
rotate relatively to each other.

Abstract: The present invention provides for a "rifle sighting system" on the top surface of the clubhead which allows the goifer at the address position to align the ball where the center marker on the clubface will be at impact. This system factors in the effect the downward bowing of the shaft on the forward swing has on the center of the clubface's position at impact. It also factors in the parallax visual error the golfer experiences as he tries to align the center of the clubface to the ball.

Abstract: A flashless catheter beveling process in
which a beveling catheter mold has an internal cavity
which defines the external beveled shape of the
catheter and also has a circular hole centrally
located therein. In the beveling mold, one end of a
distal endmost interior bevel terminates at the
surface of the beveling mold, with the distal endmost
bevel and the surface forming an angle at the edge of
the circular hole. A cylindrical support pin is
inserted into a hollow extruded unbeveled catheter
tube. The beveling mold is heated and positioned
relative to and around the extruded catheter tube with
the cylindrical support pin positioned in the circular
hole of the mold. This arrangement melts the extruded
catheter tube to allow it to flow within and assume
the shape defined by the internal cavity of the
beveling mold, and the molten catheter material
flashes through a narrow annular gap defined between
the cylindrical support pin and the circular hole.
The cylindrical support pin is then withdrawn from the
circular hole in the beveling mold, and one end of a
cone pin is positioned in contact with the circular
hole. The cone pin contacts the circular edge formed
by the surface of the mold and the distal endmost
bevel, and pinches off the flash which has been
extruded through the annular gap. The molded catheter
is then removed from the catheter mold, and the
cylindrical support pin is withdrawn from the finished
and molded catheter.
