Patent number: 11362504Abstract: Circuits and methods for protecting against over-current conditions of switches are described. Over-current conditions can damage switches and the circuits they connect. Some embodiments of the present application provide a sense switch in parallel with the load switch. The sense switch is smaller than the load switch, and is used to sense an over-current condition of the load switch. The sense switch can remain on even when the load switch is turned off in response to detection of an over-current condition.Type: GrantFiled: July 20, 2020Date of Patent: June 14, 2022Assignee: Analog Devices International Unlimited CompanyInventors: Jofrey Generalao Santillan, David Aherne

Patent number: 11121547Abstract: The present disclosure provides a method and device for overvoltage protection. Specifically, the present disclosure provides an overvoltage protection device which provides a feedback loop for electronic components such as amplifiers and digital to analog converters which require feedback. The overvoltage protection device also includes overvoltage switches in both the signal and feedback channels, which may be opened by a fault detector in the event of an overvoltage. The device also includes an overvoltage feedback channel coupled between the signal and feedback channels, and which also includes a switch which may be closed in the event of an overvoltage event. As such, the overvoltage device provides a closed loop feedback channel during an overvoltage event.Type: GrantFiled: April 2, 2019Date of Patent: September 14, 2021Assignee: Analog Devices International Unlimited CompanyInventors: Alan Kelly, David Aherne, Aidan J.

Patent number: 11020549Abstract: A dry powder inhalation device is disclosed. In one optional aspect, the device includes a housing, a base plate, a receptacle for a medicament and a mouthpiece. The base plate is engageable with the housing to form a main space with a main air inlet. The mouthpiece includes an inner conduit connected to its outlet and is engageable with the base plate to fluidly connect the inner conduit to the receptacle. The receptacle is fluidly connected to the main space, so that upon inhalation by a user, air can be drawn through the main air inlet into the main space and onward through the receptacle into the inner conduit. The mouthpiece and the base plate form an auxiliary space with an auxiliary air inlet, wherein the auxiliary space is fluidly connected to the main space.Type: GrantFiled: August 14, 2017Date of Patent: June 1, 2021Assignee: Alfred E.
