Abstract: A  safety  needle  device  which  can  be  used substantially  as  a  regular  syringe  or  with  a  "y" connector.  The device includes an elongate barrel with a longitudinal axis and an inside surface defining a chamber which has an open proximal end and a distal end with  a  needle cannula.   The needle cannula projects distally outwardly, and has a distal tip and a lumen in fluid communication  with  the  barrel  chamber.   The device has a needle guard with a proximal first end and a distal second end.  The guard is mounted for movement relative to the barrel  from a  retracted position  in which the guard does not materially obstruct access to the distal tip of the needle cannula and an extended position   where   the   guard   substantially  prevents inadvertent  access  to  the distal  tip  of  the  needle cannula.      The needle guard is releasably retained  in the retracted position and locks in the extended position. The guard has  at  least  one  open slot which extends proximally from the second end.  The slot is sized to accept the sidearm of a "y" connector when the needle penetrates the septum of the "y" connector and the bore of the connector  is  in  fluid communication with the chamber of the barrel.

Abstract: An apparatus for use in Differential Optical Absorption Spectroscopy (DOAS) or in other optical apparatus provides a moveable or oscillating aperture. It has a sensor for detecting the position of the aperture, and a drive for oscillating the aperture; the drive and sensor can comprise coils forming a linear variable differential transformer, and the aperture can be spring biased to a neutral position. A control circuit is connected between the coil or other sensor and the drive coils, so that the motion of the aperture follows a desired profile. This enables significant parts of the apertures motion to be constrained to be linear. The aperture can be provided in a shuttle mounted on extension arms, whose ends are connected to resilient biassing means which serve both to support the shuttle and to bias it. More preferably, extension arms extend through pole pieces of magnets, which provide a magnetic field for drive coils. Another aspect of the invention provides a telescope apparatus, for a DOAS technique, including a baffle moveable between calibration and operational positions. This enables light from the light source to be transmitted either for measurement or for calibration allowing for changes in lamp output, etc.

Abstract: A device for combined bioaffinity assay and electrophoretic separation is provided, which comprises a capillary system having two stages, a first stage (1) in which bioaffinity interactions of analyte molecules (L,M) and molecular recognition elements (A) are performed, and a second stage (2), in which electrophoretic separation of the analyte molecules (L,M) and subsequent detection of the separated species is accomplished. Within the first capillary stage (1) the molecular recognition elements (A) are attached and immobilized to the inside capillary wall (3), for example, by adsorption or by covalent binding to the capillary material. The method for combined bioaffinity assay and electrophoretic separation comprises flowing an analyte through a capillary system having two stages. In a first capillary stage (1) the analyte molecules (L,M) are captured by respective molecular recognition elements (A) present in that stage (1). More particularly the analyte molecules (L,M) are captured by molecular recognition elements (A) which are attached and immobilized to the inside wall (3) of that capillary stage (1), for example, by adsorption or by covalent binding to the capillary material. After a predetermined time the analyte-molecules (L,M) are dissociated from the molecular recognition elements (A). Subsequently the analyte-molecules (L,M) are separated in a second stage (2) of the capillary system by capillary electrophoresis and finally the separated species are detected at the terminal part of the capillary system.

Title: Gaming machine having dynamic payout amounts
Inventor: MANZ ROBERT P
IPC: G07F17/32
Filed: 1995-06-16
Granted: 2003-01-28
Abstract: A dynamic payout system for a gaming machine permits the random selection of a payout for a particular game outcome from a predetermined range of payout amounts. The player is provided with a range of possible payouts that may be paid upon the occurrence of a particular game outcome.        When the player initiates game play, an input-output interface generates an initiate signal. A game control microprocessor, in response to the initiate signal, randomly selects a game outcome that includes a metered winning game outcome. If a winning game outcome occurs, the microprocessor then randomly selects a payout amount from a predetermined range of payout amounts stored in memory, which includes metered payout amounts. A meter display displays the metered payout amount. A payout device such as a coin hopper dispenses the metered payout amount.        The system provides additional features including a meter display that incrementally displays the metered payout amount and a coin hopper that incrementally dispenses the metered payout amount synchronously with the incremental display of the metered payout amount.

Abstract: An air gun comprises a magazine (632) with a plurality of barrels (634) with associated projectiles (670, 672). Air is compressed by a piston (623) through an outlet (637). The barrels are sequentially alignable with the outlet by an advancement mechanism (653, 664). In one embodiment, the magazine is normally biased with a spring (663) toward the outlet to create a seal (631) with the aligned barrel. Upon magazine advancement, the advancement mechanism counteracts the spring bias to reduce friction. In another embodiment, the outlet is slidable, under friction provided by the piston, into sealing contact with magazine. The gun may be mounted on a bow frame (900) to provide force to propel the piston.
