Abstract: L'invention concerne un appareil servant à détecter la présence d'articles multiples. Cet appareil comporte une plate-forme sur laquelle peuvent être placés un ou plusieurs articles ainsi qu'un détecteur, de façon à recevoir une image d'un profil de l'un ou de plusieurs des articles placés sur la plate-forme. Le détecteur est configuré et disposé de façon qu'il émette un signal correspondant au profil. Ce signal indique la présence d'articles multiples sur la plate-forme. Le détecteur peut se présenter, par exemple, sous la forme d'un détecteur de point mobile, d'un détecteur linéaire, ou d'un détecteur à tableau bidimensionnel. Cet appareil peut être utilisé conjointement avec un dispositif de vérification des stocks, tel qu'un dispositif de vérification de l'inventaire d'une bibliothèque, de façon à empêcher que des articles soient retirés du stock sans autorisation.

Abstract: Ces condensateurs à constante diélectrique élevée sont produits à l'aide d'une encre diélectrique (30, 32, 34) à base de poudres de plomb-magnésium-niobate et d'oxyde de plomb. On produit ces encres diélectriques en mélangeant les poudres diélectriques avec un véhicule organique approprié pouvant être utilisé pour enduire un ou plusieurs rubans verts à base de verre. On produit des condensateurs noyés par enduction sus-jacente et sous-jacente d'un ruban vert au moyen d'un agent conducteur (36, 38, 40, 42) tel que de l'argent. Il est également possible de produire ces condensateurs en adaptant le véhicule organique et en formant un ruban vert à l'aide de poudres diélectriques. Ces rubans verts diélectriques peuvent être revêtus d'une couche conductrice et empilés, les couches conductrices étant connectées en parallèle. Les condensateurs multicouches résultants sont dotés d'une constante diélectrique élevée en comparaison de celle des condensateurs à une seule couche et il n'est plus, dès lors, nécessaire de concevoir des condensateurs à superficie très importante.

Abstract: A method of forming a weld between workpieces (1, 2) over a joint region (3).  The method comprises: exposing the joint region (3) to incident radiation (4) having a wavelength outside the visible range so as to cause melting of the surface of one or both workpieces at the joint region, and allowing the melted material to cool thereby welding the workpieces together. A radiation absorbing material is provided at the joint region (3) in one of the workpieces (1,2) or between the workpieces which has an absorption band matched to the wavelength of the incident radiation so as to absorb the incident radiation and generate heat for the melting process. The absorption band lies outside the visible range so that the material does not affect the appearance of the joint region (3) or the workpieces (1, 2) in visible light.

Abstract: Rapidly dispersing solid dry therapeutic dosage form comprised of a water insoluble compound existing as a nanometer or micrometer particulate solid which is surface stabilized by the presence of at least one phospholipid, the particulate solid being dispersed throughout a bulking matrix. When the dosage form is introduced into an aqueous environment the bulking matrix is substantially completely dissolved within less than 2 minutes thereby releasing the water insoluble particulate solid in an unaggregated and/or unagglomerated state. The matrix is composed of a water insoluble substance or therapeutically useful water insoluble or poorly water soluble compound, a phospholipid and optionally also at least one non-ionic, anionic, cationic or amphipathic surfactant, together with a matrix or bulking agent and if needed a release agent. The volume weighted mean particle size of the water insoluble particle is 5 micrometers or less.
Patent CA-2351971-C (CA)
Title: Apparatus and method for acquiring an uplink traffic channel in wireless communications systems
Inventor: LI JUNYI
IPC: H04J11/00
Filed: 2001-06-29
Granted: 2005-11-01
Abstract: Uplink traffic channel allocation is realized by utilizing a dedicated control channel in which a prescribed portion of the control channel resource, for example, frequency, time slot or the like, is reserved for transporting the uplink traffic channel requests. Both the base station and the particular mobile unit know the prescribed portion of the control channel resource a priori. Consequently, when the particular mobile unit transmits an uplink traffic channel request via the prescribed portion of the control channel resource there is no need for adding any control header information, thereby minimizing overhead. Furthermore, the length of the uplink traffic channel requests can be optimally chosen without constraints imposed by other control message schemes. Reduced overhead coupled with the prescribed portion of the control channel resource arriving quite frequently reduces latency in the particular mobile unit acquiring an uplink traffic channel. In one example, delivery of adequate uplink traffic channel request information to the base station, while minimizing the adverse impact of losing requests, is ensured by persistently transmitting the requests. Specifically, after the mobile unit transmits a first request, it transmits a second or even a third request instead of waiting to receive a response message from the base station and/or waiting for a timer to time out. By the mobile unit using such a persistent request transmission scheme, the base station can readily determine the true value of the received request by eliminating the transmission loop delay effect, thereby allowing a sensible assignment decision to be made.
