Abstract: The present invention is a fiber optic waveguide adapted for focusing a beam of light at an obtuse angle to the optical axis. A focusing end of the fiber optic is polished at an angle such that the surface normal does not coincide with the optical axis, which is defined by the path of the beam of light through the fiber optic waveguide. The angle .theta. is necessarily greater than 0 degrees and less than 90 degrees.

The focussing lens may be a ball lens, and it is attached to the exterior of the cladding layer by an adhesive material.
Patent CA-2467483-A1 (CA)
Inventor: FRANZKE GERD
IPC: D04B21/14
Filed: 2002-12-19
Abstract: The invention relates to a method and a system for producing a multi-layer thread or fibre arrangement (GF) which is pre-fixed by means of a loop structure and is used as a strip-type semi-finished product for reinforcing elements consisting of plastic or resin. Said fibre arrangement (GF) comprises layers consisting of stationary weft yarns (K) and layers consisting of thread or fibre warps (S, D, D') which are stretched between conveyor chains in such a way that they are oriented in different directions. The aim of the invention is to reduce the costs and the required surface mass, simultaneously maintaining defined, required flexural strength. To this end, the method is designed in such a way that the stationary weft layer (KR) consisting of fibre or thread warps and oriented parallel to the working direction is located directly adjacent to the needle loops (WN) of the loop structure, and needle loops (WNv) of the loop structure cross the threads or fibres of the stationary weft layer, in the knock-over phase, before the knitting needles (1) penetrate the thread arrangement (G) in order to create a successive row of loops.

Abstract: A common platform for Direct Broadcast Satellite (DBS) networks can transmit common programming among distinct DBS networks to the DBS receivers of both networks. By providing a common platform that can broadcast common television services to DBS receivers of two or mare DBS networks, the DBS  networks themselves can broadcast additional services, such as high definition TV  and/or data services, using spectrum that is freed-up by the common platform. DBS  receiving systems can include first and second DBS receivers. The first DBS receivers are configured to receive a first broadcast signal including first television services from a first satellite television network (for example, DirecTV). The second DBS  receivers are configured to receive a second broadcast signal including second television services from a second satellite television network (for example, EchoStar).  At least some of the first and second receivers are also configured to receive a common broadcast signal including common television services, from a common platform satellite television network.

Title: Gaming machine having a player time-selectable bonus award scheme and an intelligent button
Inventor: CANTERBURY STEPHEN A
IPC: G07F17/32
Filed: 2004-06-29
Abstract: The present invention is a gaming machine having a player time-selectable bonus award scheme whereby the player may redeem, at a time of the player's choosing winning outcomes accrued during base game play.      Redemption of each of the accrued winning outcomes is accomplished when a player selects an option to display a winning symbol combination associated with the winning outcome. Selection of the option to display the winning symbol combination associated with the winning outcome always yields an award and sometimes yields another winning outcome, again redeemable at a time of the player's choosing. A counter display on an intelligent button of the gaming machine increments a number as each winning outcome is accrued, and decrements the number as each winning outcome is redeemed. Thus, a second game may be initiated before a first game is complete.

Title: Fluid pump
Inventor: VINCENT DOUGLAS
IPC: A61M1/12
Filed: 2003-02-21
Abstract: A pumping system 10, FIG. 1, provides a physiological pulsatile flow and includes controller 121, a pump drive head 50 coupled to a motor 12 and a fluid housing 52 having at least one port 60. The port 60 includes a ball valve retainer region 69, a valve seat 73, and an occluder ball 71 disposed in the ball valve retainer region 69. During operation, the motor 12 forces the fluid in and out the fluid housing 52 and causes the occluder ball 71 to move from a first position whereby the fluid cannot pass through the port 60, to a second position whereby the fluid moves annular to and generally around the occluder ball 71. This movement creates a slight flow reversal that "breaks up" any blood clots that may form. The pumping system may be used as part of a cardiopulmonary bypass system, a ventricular assist device (VAD) and/or a heart pump.
