Abstract: A wearable electronic device includes an electrode array for transdermal stimulation of a sensory nerve that itself innervates a body part distal to a worn location of the wearable electronic device. The transdermal stimulation is configured to induce an electrical current or voltage that evokes a sensory impression at an area innervated by the sensory nerve, not at the stimulated sensory nerve itself. In one implementation, the wearable electronic device takes a finger ring form factor worn on a proximal phalanx of an index finger. In this configuration, the wearable electronic device can stimulate a portion of a branch of the median nerve extending through the index finger. Upon stimulation of the median nerve, a user wearing the finger ring may perceive pressure applied to the user's fingertip.

Abstract: A hydroponic growing system is presented. The system can include multiple growing trays in a vertical arrangement, where a pump supplies the top-most tray and each lower tray is supplied by the overlying tray, and where the plumbing elements for supply and drainage are arranged to one side of the system. The system includes variations to support different crop types within the same system, including removable growing structures for root vegetable, microgreens and supports for vining crops. The system can monitor and adjust the nutrients and other features of the systems water profile to concurrently group multiple crops in differing developing stages.
