Title: Orthogonal frequency division multiplexing based spread spectrum multiple access
Inventor: LAROIA RAJIV
IPC: H04W72/04
Filed: 2000-02-11
Granted: 2005-06-07
Abstract: An orthogonal frequency division multiplexing (OFDM) based spread spectrum multiple access system using offsetting between cells, and in particular, the use of tone offsetting and time offsetting, is disclosed. More specifically, frequencies that define the tone set of one cell is offset from the frequencies that define the tone set of at least one adjacent cell. In other words, if a first base station is using tones F1, F2, ..., F N within a frequency band, then a second base station adjacent to the first base station uses tones F1+.DELTA.f, F2+.DELTA.f ..., F N+.DELTA.f within the same frequency band.  Furthermore, the symbol timing of the base-station of one cell may be offset from the symbol timing of the base-station of an adjacent cell. Thus, if a first base station starts successive symbols at times T1, T2, and T3, then a second base station adjacent to the first base station starts its respective corresponding successive symbols at times T1+.DELTA.t, T2+.DELTA.t, and T3+.DELTA.t. For example, in a cellular system with hexagonally shaped cells, the tone sets of two adjacent cells are offset by 1/3 of the spacing between adjacent tones, and the symbol timings of two adjacent cells are offset by 1/3 of a symbol period. Advantageously, the intercell interference is more uniformly distributed among users in a cell.

Abstract: A storage assembly includes a storage cabinet removably mounted to a wheeled base which is supported by a supporting surface such as a floor. A guide assembly is interconnected with the floor and the base for guiding movement of the base in a longitudinal direction, so as to provide movement of the storage cabinet between an extended position and a retracted position in response to application of an axial pull-out or push-in force to the cabinet. A releasable retainer mechanism is interposed between the base and the guide assembly for releasably retaining the storage cabinet in either its extended position or its retracted position. The storage cabinet is removably mounted to the base by a removable mounting arrangement which requires a minimum number of tools to secure the storage cabinet to the base and which provides quick and easy mounting and demounting of the storage cabinet relative to the base.

Title: Permanent tamper resistant bar code labels for tires
Inventor: NICOLA BRUCE EDWARD
IPC: B60C13/00
Filed: 2000-06-19
Granted: 2009-12-22
Abstract: A process for labeling tires with a bar code is described which results in bar code labels that do not release from the tire during use and are consistently readable with bar code scanners. The labels use a rubber backing that bonds to the green tire during curing. A protective film on the labels protects the bar code during tire curing and can be removed thereafter or can become detached during use. An adhesive on the contact side of the label assures that the labels do not fall off or become misaligned prior to tire curing.

Abstract: The invention concerns a 5-aminolevulinic acid ester (E-ALA) solution for producing a pharmaceutical preparation useful for diagnosing and/or treating tissue and/or cell pathologies by local radiation exposure using radiation emitted by a light source energy followed, in the case diagnosis, by detection of fluorescent protoporphyrin IX (Pp1X). The E-ALA concentration in the solution is less than 1% and ranges between 0.01% and 0.5%. The low E-ALA concentration in the solution increases Pp1X synthesis and homogenises its distribution in the cell layers while highly reducing the secondary toxicity for the treated cells.

The invention also encompasses the operation of radio frequency receivers which utilize the. above method, as well as apparatus that performs the above method and radio frequency receivers which utilize the above equalization method.

Abstract: Procédé qu'on utilise pour créer des défauts contrôlés correspondant à des pailles naturelles et à des contraintes résiduelles dans différents types de pièces d'essai. Des défauts identiques à des pailles naturelles sont nécessaires pour qualifier des essais non destructifs (NDT). Ce procédé consiste à mettre en application des cycles séquentiels et répétitifs de réchauffement et de refroidissement afin de créer des défauts et des contraintes résiduelles. On utilise la forme de la configuration de réchauffement et de refroidissement, la durée du réchauffement et du refroidissement et le nombre de cycles thermiques afin de vérifier la dimension des défauts et des contraintes résiduelles obtenus. On crée le défaut sans paille initiale ou autre agent de nucléation. Les défauts correspondent à des pailles naturelles en termes de morphologie et également de signaux obtenus au moyen de procédés d'essais non destructifs et sont appropriés, par exemple, pour être utilisés dans des blocs de qualification d'essais non destructifs (NDT).

Granted: 2006-11-21
Abstract: Method and apparatus for controlled copying of an audio or video signal transmitted over a cable television or direct satellite broadcast system or the Internet. Copyrighted (or other) audio or video material is protected from unwanted copying (recording) by the combination of a watermark embedded in the audio or video signal at the head end together with additional copy protection data inserted in the audio or video signal, either a ticket or a second watermark. Video line (21) in the vertical blanking interval for (NTSC TV) is used to hold the ticket (cryptographic counter). A n audio or video watermark is embedded in the active portion of the audio or video signal. Only if the consumer is willing to pay a fee is the video signal with both the watermark and the ticket transmitted to his recording device which then matches the watermark to a mathematical function of the ticket, and only if they match is recording permitted. Alternatively, this consumer control may operate on a second watermark in the audio or video. The corresponding playback device outputs an audio or video signal which doe s not have the ticket and hence no further copying is permitted. This enables a single copy to be made upon payment.
