IPC: H04B1/707
Filed: 1998-06-08
Abstract: An additional information produced by an additional information signal producing means is spectrum-spread by a spectrum spreading code generated on the basis of the timing of the synchronous signal of digital video signal and is then added to the digital video signal by means of a signal adding means.  The digital video signal to which the spectrum spread additional information signal is added is then written into a recording medium by a signal writing means   Thereby, the additional information signal can be added to the video signal under the condition that the reproducing quality of the video signal is never deteriorated and alteration and deletion are impossible and moreover the additional information signal can be detected for use as required from the video signal.

Abstract: Procédé permettant le transfert entre les centres de commutation mobile (MSC-A, MSC-B) d'un réseau cellulaire mobile dans la transmission de données à haute vitesse où plusieurs canaux sont affectés à une station mobile (MS). Selon le procédé, le premier centre de commutation mobile (MSC-A) signale au second centre de commutation mobile (MSC-B) le nombre minimal de canaux nécessaires pour la liaison. Le second centre de commutation mobile (MSC-B) tente d'attribuer au moins le nombre minimal de canaux ainsi signalé. Le second centre de commutation mobile (MSC-B) transmet au premier centre de commutation mobile (MSC-A) des données concernant les canaux qu'il a attribués ainsi qu'un numéro de transfert (HON). Le premier centre de commutation mobile (MSC-A) peut utiliser le même numéro de transfert (HON) pour effectuer le transfert vers chaque sous-canal.

Title: A method and apparatus for controlling thickness during lay-up and fabrication of press-cured composite articles
Inventor: DAVIS GEOFFREY C R
IPC: B29C43/20
Filed: 1997-03-10
Abstract: A method and apparatus for controlling the thickness of press-cured composite articles during the manufacture thereof. The method includes a preparatory or fabrication stage (12) wherein prepreg plies are layed up (16) and compacted (18) to form a plurality of laminates that define a final laminate package that defines the uncured configuration of the composite article. The final laminate package may include supplemental ply-packs layed up at the mid-plane or neutral axis of the final laminate package for the purpose of controlling the overall thickness of the final laminate package. The prepreg plies layed up in the preparatory stage have been precut to conform to the final net shape of the composite article, but include a predetermined overbuild in the width dimension to facilitate control of thickness during cure of the final laminate package. The method further includes a fabrication stage (28) wherein a deformable, back-pressure system is abutted in combination with the final laminate package (32), which is then subjected to a cure cycle (36) to form the cured composite article. The deformable, back-pressure system is controllably deformed during the cure cycle to control and limit the lateral expansion of the final laminate package. The deformable, back-pressure system also prevents fiber washout during cure cycle.

Title: Distance indicator system for golf
Inventor: GOSS KEN
IPC: A63B57/00
Filed: 1998-11-20
Abstract: A golf distance indicator system provides measurement and display of the distance between a golfer and the pin on the green he is approaching.  The system comprises a portable unit carried by the golfer and an target unit located on the pin.  With the portable unit, the golfer selects the hole he is playing then activates the system.  The portable unit sends a wireless coded message to an intended target unit.  When a target unit receives a message, it analyzes the message to see if it should respond.  If the target unit determines that it should respond, it sends a coded responding message to the portable unit.  When the portable unit receives a responding message, it analyzes the responding message to see if the responding message originates from the intended target unit.  If it does, the portable unit calculates a distance based on the elapsed time for the communications and the speed of the communications.   The results are displayed on the portable unit.
