Abstract: A medicament delivery device (100) for delivery of medicament from a cartridge (10) into an injection site, through a cannula (134). The cartridge has a medicament chamber (14) with an outlet (15), and a sealing element (16) for closing the outlet (15). The device has a housing (102) for receiving the cartridge (10), and a drive mechanism (200) to expel the medicament from the device upon activation of the drive mechanism (200). The device has a connection arrangement (199) comprising a hub (166) and spring means (184) for driving relative movement between the hub (166) and the cartridge (10) upon operation of an operating member (190). The operating member switches the connection arrangement (199) from an unconnected configuration to a connected configuration, in which the hub (166) cooperates with the cartridge (10) to open the outlet (15). When connected, fluid may flow between the chamber (14) and the cannula (134).

Abstract: A cartridge (100) for packaging a medicament and being suitable for use with multiple different types of dosing device is described, together with dosing devices and adaptors for dosing devices. The cartridge includes a generally tubular body (102) having an interior cavity (104), a closure member (106) disposed at a distal end of the body and comprising a sealing element (128), a piston member (108) disposed in the cavity to contain the medicament between the piston member and the sealing element (128), a coupling element (114) disposed at the distal end of the body for coupling the cartridge to a dosing device (200) or to an adaptor for a dosing device, and a seal arrangement (126, 129) for receiving a sealing element release member (214) of the dosing device or adaptor.

Abstract: A needle tip (22) for being connected and disconnected in use from a needle tip support (16), comprises a needle (24) having a forward end and a rearward end and, a connector secured to the needle intermediate its ends. The connector comprises two arms (28) each extending outwardly and rearwardly relative to the needle (16) and configured to be coupled and uncoupled in use from said needle tip support, and the arms are disposed on opposite sides of the needle. Also disclosed are arrangements for storing, dispensing and later disposing such needle tips, as well as coupling interfaces between the needle tip and a needle support cap to which it is fitted in use.

Abstract: An auto-injector for receiving a primed syringe includes: a plunger driver for coupling to a plunger head of the syringe when the syringe is fitted within the auto-injector, and configured to drive a plunger into a barrel of the syringe, wherein the plunger driver positioned on the auto-injector such that it is below the plunger head when the syringe is primed and fitted within the auto-injector.

Abstract: A method of programming a tire pressure monitor sensor utilizes a programming tool that transmits LF data frames to the TPMS sensor that includes a cyclic redundancy check (CRC) code with each data frame. The starting point for the subsequent data frame will then start with the CRC code received from the previous frame and will end with a new CRC code. Accordingly, the CRC code received from the previous frame will be used to ensure that the next data frame matches that CRC code as the starting point for that frame. This will ensure that the data frames cannot get out of sequence and will allow the ability to quickly identify where the data frames have gone out of sync and allow the programming tool to quickly react.
