Title: A multi-wavelength optical pump
Inventor: KERFOOT FRANKLIN W III
IPC: G02F1/35
Filed: 1997-10-15
Abstract: A high-powered optical pump (15) includes at least two sub-pumps (36, 37).  Each sub-pump (36, 37) generates a light at different wavelengths. The outputs of the sub-pumps (36, 37) are coupled to a remote pump fiber (15). The resulting light transmitted on the remote pump fiber (15) results in a lower raman gain and raman noise spectral peak than that generated by existing single wavelength high-powered optical pumps at the same power level. Therefore, increased power can be transmitted on the remote pump fiber (15) in contrast to a single wavelength pump.

Title: Treatment of disease states which result from neoplastic cell proliferation using ppar-gamma activators and compositions useful therefor
Inventor: EVANS RONALD M
IPC: A61K31/445
Filed: 1997-12-29
Abstract: In accordance with the present invention, it has been discovered that PPAR.gamma. is expressed consistently in tissues associated with each of a variety of disease states which result from neoplastic cell proliferation. It has further been discovered that maximal activation of PPAR.gamma. with exogenous ligand promotes terminal differentiation of primary cells which are otherwise subject to neoplastic cell proliferation. In accordance with another aspect of the invention, it has been discovered that RXR-specific ligands are also potent agents for induction of differentiation of cells expressing the PPAR.gamma./RXR.alpha. heterodimer, and that simultaneous treatment of cells subject to neoplastic cell proliferation with a PPAR.gamma.-selective ligand, in combination with an RXR-specific ligand, results in an additive stimulation of differentiation. Thus, the effect of neoplastic cell proliferation can be ameliorated by treatment of cells undergoing neoplastic cell proliferation with PPAR.gamma. agonists, optionally in the further presence of RXR agonists, thereby blocking further proliferation thereof. Accordingly, compounds and compositions which are useful for the treatment of a variety of disease states which result from neoplastic cell proliferation have been identified and are described herein.

Patent CA-2280203-A1 (CA)
Title: An arrangement for synchronization of a stream of synchronous traffic delivered by an asynchronous medium
Inventor: PETTY NORMAN W
IPC: H04J3/06
Filed: 1999-08-10
Abstract: An ATM cell constructor of an ATM transmitter assembles a stream of frames of constant bit-rate traffic received on a listen TDM bus into cell payloads using ATM adaptation layer 1 (AAL1). Once every eight cells, the AAL1 structured data transfer (SDT) cell constructor layer introduces a one-octet SDT offset pointer into the payload. This pointer designates traffic-block (TDM frame) boundaries. The payload with an attached ATM header forms an ATM cell, and the constructor transmits a stream of the ATM cells to an ATM cell deconstructor of an ATM receiver.    The deconstructor disassembles the payloads of the received ATM cells and transmits the stream of frames of constant bit-rate traffic on a talk TDM bus. In response to each received SDT offset pointer, the deconstructor's time slot interchanger (TSI) resets to the start of frame-processing, thereby aligning frames formed by the TSI with the received frames. The deconstructor detects occurrence of TDM frames on the talk TDM bus and synchronizes (aligns) transmission of the frames formed by the TSI with the TDM frames on the talk TDM bus. The listen and talk TDM buses are thereby synchronized with each other.

Title: Appat artificiel pour poisson
Inventor: PAAP KARL-LUDWIG
IPC: A01K85/16
Filed: 1998-04-01
Abstract: Pour la pêche au gros, on utilise des appâts artificiels. Ces appâts sont habituellement tirés dans l'eau par le pêcheur comme une cuiller ondulante ou un appât scintillant de telle manière qu'ils imitent avec leur forme cambrée les mouvements d'un vrai poisson. Cependant, l'imitation de la nature par certains appâts connus demeure souvent insuffisante et donc inopérante sur des poissons particulièrement attentifs. Aussi l'appât artificiel proposé présente-t-il une nageoire caudale (3) qui peut être manoeuvrée activement dans un sens et dans l'autre par l'intermédiaire d'un élément de traction (9) en prise avec les deux flancs (12, 13). Grâce à des pauses supplémentaires marquées dans le déroulement du mouvement et à une conception élastique de la nageoire caudale (3), on parvient à une imitation particulièrement trompeuse du mouvement d'un vrai poisson, laquelle garantit une efficacité optimale d'appât, y compris avec les gros prédateurs.

Abstract: La présente invention a trait à une aiguille chirurgicale qui possède un orifice distal ouvert, dans lequel est posé le tissu à fracturer, et contient une fibre optique pour fournir des impulsions d'énergie laser ainsi qu'une cible en titane destinée à recevoir ces impulsions. La cible convertit l'énergie des impulsions électromagnétiques en ondes de choc qui heurtent le tissu dans l'orifice et fracturent le tissu. Comme la cible possède une ou plusieurs marches, la vaporisation de la cible par les impulsions laser laissent une surface directement opposée à l'orifice; de cette manière, la conversion continue de l'énergie laser en ondes de choc mécaniques fournit des ondes de choc qui ne sont pas bloquées dans leur course vers l'orifice dans lequel est disposé le tissu.
