Abstract: A method of manufacturing a series of incremental dose counters for inhalers, which includes manufacturing the dose counters with nominal canister fire and dose count positions of a dose counter actuator relative to a dose counter chassis or inhaler main body, and which includes building the dose counters with an average dose count position in the series being, in canister fire process, at or after an average canister fire position in the series.

Abstract: A dose counter for a metered dose inhaler includes an incremental counting system for counting doses. The incremental counting system has a main body, an actuator arranged to be driven in response to canister motion and to drive an incremental output member in response to canister motion. The actuator and incremental output member are configured to have predetermined canister fire and count configurations in a canister fire sequence. The canister fire configuration is determined by a position of the actuator relative to a datum at which the canister fires medicament and the count configuration is determined by a position of the actuator relative to the datum at which the incremental count system makes an incremental count. The actuator is arranged to reach a position in the count configuration at or after a position in the canister fire configuration.

Abstract: A dose counter for an inhaler, the dose counter having a display tape arranged to be incrementally driven from a tape stock bobbin onto an incremental tape take-up drive shaft, the bobbin having an internal bore supported by and for rotation about a support shaft, at least one of the bore and support shaft having a protrusion which is resiliently biased into frictional engagement with the other of the bore and support shaft with longitudinally extending mutual frictional interaction.

Abstract: An incremental dose counter for a metered dose inhaler having a body arranged to retain a canister for movement of the canister relative thereto, the incremental dose counter having a main body, an actuator arranged to be driven and to drive an incremental output member in a count direction in response to canister motion, the actuator being configured to restrict motion of the output member in a direction opposite to the count direction.

Abstract: A manually operated metered dose inhaler includes a dose counter chamber including a dose display tape driven by a ratchet wheel which is driven in turn by an actuator pawl actuated by movement of a canister, the tape unwinding from a stock bobbin during use of the inhaler, a rotation regulator being provided for the stock bobbin and including a wavelike engagement surface with concavities which engage against control elements in the form of protrusions on resilient forks of a split pin thereby permitting incremental unwinding of the stock bobbin yet resisting excessive rotation if the inhaler is dropped onto a hard surface.

Abstract: A decoding apparatus includes at least one data input terminal receiving a program transport stream from an external set-top box. A decoder decodes the program transport stream and a data output terminal outputs the decoded content to an external device. The program transport stream is the same transport stream received by the external set-top box from a service provider.

Abstract: A multi-stage filtering and treatment apparatus comprising a minimum of three stages, wherein the first stage comprises a container for separation of large scale aggregate or particulate matter from the washout slurry, the second stage comprises a container for separation of small scale aggregate or particular matter from the washout slurry, and the third stage comprises a container for separation of suspended particles and fines from the washout slurry and adjustment of the pH as needed. Each such stage comprises a pass-though container that temporarily retains the washout liquid before allowing passage of liquid from one stage container to the next and then out of the apparatus altogether.

Abstract: In a method of managing 3D video stream, 3D video stream is output to a connected display. The connected display displays the 3D video stream after a delay associated with the connected display. A timing offset is determined based on the delay. The timing offset is operable to be used to synchronize shutter operations of at least one shutter glasses with the presentation of the 3D video stream. A shutter control signal based on a frame start indication from the 3D video stream is transmitted. The frame start indication is operable to be used to determine a frame rate of the 3D video stream, and the shutter control signal is operable to be used to maintain synchronization of the shutter operations of the at least one shutter glasses with the presentation of the 3D video stream at the connected display.

Abstract: Shield means are provided for use on data input apparatus. The shield means includes a housing or frame with at least one channel defined therethrough. The at least one channel has a first end and a second end and is arranged such that a user can view the first channel end in a first position when the user is looking through the second channel end and the user's line of vision is substantially parallel with the longitudinal axis of said channel, thereby allowing data and/or data input means associated with or below the first channel end to be viewed by the user in the first position. The view of the first channel end is substantially obscured or shielded from the user in at least a second position when the user's line of vision is at an acute angle to said channel longitudinal axis.
