Abstract: Current sensing devices that are capable of surviving harsh ambient environment of ocean worlds, such as Jupiter and Saturn moons are disclosed. The described devices can meet 300 Krad radiation requirements and can survive at cold temperatures down to ?184° C. Exemplary implementations of the constituent circuits of the devices are presented. A scheduling algorithm to perform various measurement by the disclosed current sensing devices is also described.

Abstract: A spray measuring device/system and method can include a device, and the use of the device, that incorporates an actuation device, an illumination device, and a camera that obtains data relative to a spray event via a single exposure of the camera shutter. The actuation device can be configured to actuate a spray device such as a metered dose inhaler to create a spray event. The camera can include a shutter configured to open and close a single time during the spray event to obtain a single exposure or single image of the spray event. A controller can be provided in communication with the actuation device, the camera and an illumination device, and can be configured to cause the shutter of the camera to open one single time during the spray event. The illumination device can be an LED light source.

Abstract: A system for actuating a dispensing device includes an apparatus for holding and actuating the dispensing device that includes a linear motor including a stator component and a forcer component and a frame that orients components of the linear motor relative to each other and relative to the dispensing device. The system further includes a controller configured to control the linear motor and a device that interfaces with the controller and provides a user interface for control of the system. The controller is configured to generate control signals that cause the apparatus to perform at least one actuation cycle specified by an operator. The device that communicates with the controller generates a command sequence based on the at least one actuation cycle specified and the controller generates signals based on the command sequence that cause the system to perform the at least one actuation cycle.
