Abstract: The invention is a system and method for efficient filtering, clustering, tracking and persistent motion detection for event cameras. More particularly, embodiments of the present invention combine compatible asynchronous event filtering and clustering techniques in a computationally efficient way to identify and track objects in the field of view that exhibit persistent motion characteristic of marine vessels, cars, aircraft, and other vehicles while ignoring dynamic background elements that move in a more erratic fashion.

Abstract: A detection device detects the presence of a chemical or biological agent in an environment. The detection device includes a metal layer including a plurality of electrodes. The device further includes a graphene layer covering a surface of the metal layer of electrodes and a detection layer connected to the electrodes. Contact of a biological or chemical agent with a surface of the graphene layer causes a change in resistance of the graphene layer. The detection layer includes detection circuitry configured to detect the change in resistance as a function of a measured change in a current or voltage between adjacent electrodes.
