  • Patent number: 9112496
    Abstract: A circuit and a system that uses the circuit for connecting a plurality of input channels to a receiving device. The circuit includes a plurality of DMOS switches, each of which connects a respective one of the input channels to the receiving device in response to a respective control signal. The control signals are referenced to a ground signal. Each input channel includes a common mode voltage that is non-referenced to the ground signal. The circuit also includes a switch driver that generates the control signals such that the input channels are activated one at a time.

  • Patent number: 8829975
    Abstract: A method and corresponding circuits for operating a parallel DMOS switch that includes a pair of P-type DMOS devices connected in series with each other and in parallel with a pair of N-type DMOS devices connected in series with each other. The method and circuits involve turning the switch on by applying gate signals to the DMOS device pairs which are generated using at least one source voltage of a DMOS device pair. The switch is turned off by setting the gate signals equal to the respective source voltages of the DMOS device pairs.

  • Patent number: 8710541
    Abstract: A bi-directional switch circuit includes a pair of N-type MOS devices connected in series with a common source terminal, and a pair of P-type MOS devices connected in series with a common source terminal. The series connected N-type devices are connected in parallel with the series connected P-type devices in a configuration that includes a first input/output (I/O) point of the switch circuit being connected to a drain of a first one of the N-type devices and a drain of a first one of the P-type devices. The parallel configuration also includes a second I/O point of the switch circuit being connected to a drain of a second one of the N-type devices and a drain of a second one of the P-type devices.

  • Patent number: 7854226
    Abstract: A powder inhaler includes a container for storing powdered medicament. A metering member has a dosing recess and is moveable between a filling position in which the dosing recess is in alignment with an opening of the container, and an inhalation position in which it is in alignment with an inhalation channel. A mouthpiece is in communication with the inhalation channel for enabling inhalation of the dose of powdered medicament when in the inhalation position. A protective member provided between the metering member and the inhalation channel is moveable between a closed position in which the protective member covers the dosing recess, thereby preventing powdered medicament contained in the dosing recess from entering the inhalation channel, and an open position in which the protective member does not cover the dosing recess, thereby exposing the dosing recess to the inhalation channel for enabling inhalation of the dose of the powdered medicament.

  • Publication number: 20070137645
    Abstract: An inhaler (1) is disclosed. It comprises a housing (2) to receive a strip (6) of blisters (6a) each having a puncturable lid (6c) and containing a dose of medicament for inhalation by a user, a mouthpiece through which a dose of medicament is inhaled by a user and, an actuator (3) operable to sequentially move each blister into alignment with a blister piercing member (7, 9). The actuator is also operable to cause the blister piercing element to puncture the lid of a blister such that, when a user inhales through the mouthpiece, an airflow through the blister is generated to entrain the dose contained therein and carry it but of the blister and via the mouthpiece into the user's airway.

  • Publication number: 20050261558
    Abstract: A disease risk evaluation and education tool, preferably implemented in logic on a computing device such as a Personal Digital Assistant, permits a user to input patient-specific data relevant to evaluating that patient's risk for a particular disease, e.g., coronary heart disease. The tool's logic calculates the equivalent age of the patient, based on the Framingham data set and on the input data, and presents one or more treatment recommendations.
