Abstract: A brain computer interface for interfacing with a brain of a subject is provided. The brain computer interface includes one or more shanks. Each shank includes an array of pixels and output traces. Each pixel includes an electrode and a front-end circuit positioned at a site of the electrode. The front-end circuit is configured to reduce noise in signals recorded by the electrode, and further configured to multiplex the signals. A density of power consumption of the each pixel is equal to or less than 1 ?W per area of 50 ?m by 50 ?m. The output traces are electrically coupled with the array of pixels. A number of output traces is less than a number of pixels in the array due to multiplexing. The one or more shanks are configured to be inserted on and/or into a brain of a subject.

Abstract: A combined container holder opener and cap, having an end portion with at least a pair of locking tabs. Holding the holder container in a first position the end portion serves as a base for holding a beverage container in drinking mode, and holding the holder container in a second, inverted position the end portion is a cap for holding the beverage container in capped mode.
