Abstract: A volumetric detection system (or leak tester) is disclosed herein. While the system can have any suitable feature, in some cases, it includes a displacement mechanism (such as a programmable stepper motor), a controllable element (such as a piston) that is coupled to the displacement mechanism, a containment chamber that receives a portion of the controllable element, a sensing unit (or sensor) that is configured to measure a backpressure from a device that is being tested, a computational unit (or processor) that is configured to determine a placement of the controllable element within the chamber, and a coupler (or attachment mechanism) that is configured to couple to the device that is to be tested. In some cases, the system functions without being coupled to a compressed air source. Other implementations are described.

Abstract: A method and system for controlling access to a first computing device by a second computing device, said method comprising: detecting whether said first computing device is being used by a local user; receiving an input event for said first computing device, determining whether said received input event is a local input event from said local user or a remote input event from said second computing device; and blocking said received input event if said received input event is determined to be a remote input event and if said first computing device is detected as being used by said local user.

Abstract: A first computing device for controlling a second computing device, the first computing device comprising a processor; a display; a user input in the form of a pointer; and a data link for connecting said first and second computing devices. The display displays image data from said second computing device within a window that is smaller than said display. The processor is configured to determine that said pointer has left said window; responsive to determining said pointer has left said window, determine an intersection point on an edge of said window, said intersection point being a location at which the pointer left said window; determine whether said intersection point is within a threshold distance from a nearest corner of said window; and responsive to determining said intersection point is within said threshold distance, output a message to said second computing device that said pointer is positioned on said nearest corner.
