Abstract: Apparatus for the metered supply of an analysis liquid (7) onto a target (5), which involves ejecting the liquid in small quantums, in a pulsating manner, from a nozzle (2) through a nozzle outlet orifice (3) onto the target. So as to permit precise metering of analysis liquid quantums which are distinctly larger than in the case of the "drop on demand" methods used hitherto for analysis liquids, but, on the other hand, are smaller than the minimal metered amounts achievable hitherto using diluters and dispensers, an apparatus is proposed which has a pressure chamber (1) in which the analysis liquid is pressurised, and in which apparatus a valve device (11) having a valve orifice (23) and a closure element (13) moved by an actuator (12) is provided, the valve device (11) being designed in such a way that ejection of the liquid is assisted by the movement of the closure element (13) when closing the valve orifice (23). <IMAGE>

Patent CA-2089579-A1 (CA)
Inventor: MACDONALD JOHN L
IPC: G07C9/00
Filed: 1991-08-14
Abstract: A document security system is described for encoding documents such as credit cards, chargecards and the like with a unique signal representative of the user which cannot be read by the unaided eye and can only be read using a document reading means such as a card swipe machine. In a preferred arrangement the signature (20) of a user is digitised by a digital scanner (22) and the digital data is compressed and magnetically encoded onto the magnetic stripe (14) of the credit card (12). The user's portrait (18) can also be digitised and printed on an anti-tamper panel (30) on the card. In use, the user presents the card (12) in a bank or store and the portrait is initially compared with the user and assuming there is a likeness, the card (12) is swiped through a card-swipe reader (38) and the encoded signature is read and displayed on an LCD-type display (40). The vendor or teller at the point of use can then compare the signature read from the card with the user's actual signature to verify the authenticity of the user.       Embodiments of the invention and a novel digital compression technique are described.

Inventor: CHANG JOSEPH J
IPC: A61M25/06
Filed: 1993-06-03
Abstract: CATHETER WITH NEEDLE GUARD                          ABSTRACT      A catheter device is described with a safety needle guard that covers and protects the needle after use of the device.  The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber.  An extension tubing is connected to the proximal end of the flash chamber, and extends past the proximal end of the needle guard.   A tubular needle guard concentrically fits and slides within the needle housing.  The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the  guard slides within the housing.  The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle.   As the needle guard  attains  its  fully  extended position  about  the needle, it locks in place in the needle housing.

Abstract: ABSTRACT           IMPROVEMENTS IN OR RELATING TO  MOBILE RADIO SYSTEMS       A cellular mobile radio system in which power control is applied and in which measurement of the relative paths losses between base station and mobiles are used to compute the stability condition.      In one system, mobiles are arranged to transmit a common known sequence at different times and the base stations are arranged to correlate against this sequence throughout the data transmission burst period to measure the signal levels from all mobiles within range. Base stations log the levels and times of reception. The data is aggregated over the network interconnecting the base stations to a common point. At this common point the timings of the unknown mobile signal reception peaks are matched to those of the known in other base stations in order to identify the mobile associated with every correlation peak.
