Abstract: This invention is in the field of medical devices. Specifically, the present invention provides fluidic systems having a plurality of reaction sites surrounded by optical barriers to reduce the amount of optical cross-talk between signals detected from various reaction sites. The invention also provides a method of manufacturing fluidic systems and methods of using the systems.

Abstract: A receiver unit for use with an electronic device such as a games player, digital video disc player or the like having a port for connection of a peripheral control device comprises: first connection means (18) allowing releasable electrical connection of the unit with the port of the electronic device; second connection means (20) allowing releasable connection of a peripheral control device, such as games pad or joystick; signal detection means (26) for receiving a signal from a remote transmitter such as a hand-held remote control device; and processing means (24) connected to said first and second connection means and to said signal detection means (26) to process received signals and supply them to said first connection means (18).

Abstract: Conventional pinball machines have various mechanisms, some of which are under the control of the user, to enable the ball in play to be moved around the playing surface. An extra mechanism which can be incorporated is a rotated striking member, e.g. of oval shape. When a ball strikes this, it is driven away in a direction which is usually not radial relative the rotational axis of the member but which tends to be more tangential.
