Patent CA-2363865-C (CA)
Inventor: MAGILL DAVID THOMAS
IPC: H04J13/00

Abstract: Exceptionally efficient operation is achieved through the use of orthogonal CDMA. That is, a much larger number of users per MHz of bandwidth can be supported in a given geographical area than can be supported with conventional CDMA. While the theoretical concept of orthogonal CDMA is not new, the present invention is based on novel implementation techniques which makes orthogonal CDMA practical in an a short range mobile telephone environment where significant multipath fading exists.      Specifically, this invention provides novel techniques for establishing the time base, frequency, and power control necessary to achieve orthogonality. Use of a high power sounding burst on the outbound link permits: 1) antenna diversity selection to minimize the probability of a faded condition, 2) local frequency locking at the subscriber terminal which avoids the requirement for a costly precision frequency standard, and 3) essentially instantaneous inbound power control based on the outbound receive signal level. This is effective since time division duplexing is used and both transmission and reception take place on the same frequency. With the short frame structure and unique placement of the sounding burst the correlation between the outbound and inbound path losses is very high. Thus, according to the invention, the signal structure and control algorithms result in a greatly reduced signal level range at the base station/PBX to achieve high efficiency in a orthogonal CDMA system. Real world effects such as filtering, multipath time spread, and time base error destroy orthogonality and introduce a degree of cross coupling between supposedly orthogonal channels.      Thus, the invention provides accurately controlled power levels in this highly dynamic environment. This invention achieves this necessary objective for efficient operation.

Abstract: Known packages for topically applying flowable cosmetic composition and especially antiperspirant or deodorant compositions include roll-ons in which the applicator for the composition is presented to the skin along the longitudinal axis of the container, with its distributing head pointing along that same axis. In the present invention, when the invention package is employed, its applicator (13) is disposed along a second axis (6) which is at an acute angle to the principal axis (5) of the container, especially at a neck angle of from 12 to 30 degrees. Preferably the body (2) of the container is frusto-conical, with an outward-facing sidewall (89) aligning with the principal axis (5) and an inward-facing sidewall (86) aligning with the second axis (6). Users find it easier to apply the formulations topically, such as in the armpits, from a package which has inclined principal (5) and second (6) axis.

Granted: 2007-01-23
Abstract: A device is provided for the articulated connection of two bodies comprising a first body, a clamping member, at least one tension member, and a second body. The first body comprises a cavity extending coaxially along a central axis. The clamping included a longitudinal axis and a coaxial bore with at least one aperture, the clamping member being complementary to the cavity and resiliently deformable in a direction orthogonal to the longitudinal axis. The at least one tension member is insertable coaxially with respect to the longitudinal axis into the bore. An axial displacement of the at least one tension member within the corresponding aperture may cause the clamping member to be expanded to contact the cavity wall and be releasably locked within the cavity. The second body is releasably connectable to the first body by means of the at least one tension member and the clamping member. A driving member is provided for displacing the at least one tension member axially relative to the corresponding aperture, wherein the driving member is connected to both the clamping member and the at least one tension member in positive axial engagement while rotatable about the longitudinal axis.

Abstract: Dans un système de transmission optique de données, des signaux optiques d'impulsions à haute fréquence sont transmis le long d'une fibre optique. Ces impulsions sont atténuées et déformées lors d'une transmission par l'intermédiaire de fibres optiques longues, ce qui rend difficile la détection de données au niveau de l'extrémité de réception. Le profil d'impulsions admissible est déterminé par un diagramme en oeil, le diagramme en oeil utilisé selon l'invention étant non symétrique par rapport aux niveaux logiques 1 et 0. En positionnant le diagramme en oeil plus près du niveau logique 0, la détection en présence de bruit introduit lors de la transmission des impulsions optiques peut être améliorée de façon significative.
