Abstract: A bottle (20) comprising an open-topped outer container (21) comprising a resilient body (22) for holding a water, an inner container comprising a flexible pouch (28) for holding a gel, a closure (24) adapted to fix to the top of the outer container thereby forming an enclosure for containing the water, a fixing (38,42) configured to allow the inner container to be suspended from the closure, an outlet that is in fluid communication with both the outer container and the inner container thereby allowing the outlet to dispense the water and the gel, a switch mechanism (41) including a switch moveable to select between placing the outlet in fluid communication with the outer container and placing the outlet in fluid communication with the inner container, and an air inlet and a one-way valve configured to allow air to flow into the outer container.

Abstract: A beverage apparatus and system is disclosed. The beverage apparatus is configurable to add flavors, minerals, vitamins, or other such additives to a source fluid, such as purified water, in response to a user's selection of settings, to provide a customized beverage. Advantageously, the beverage apparatus uses the purified water to cleanse the components that come into contact with the additive as part of the preparation of each beverage and includes this cleansing wash as part of the beverage itself, thus providing a self-cleaning apparatus that does not require a separate drain.

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: In some examples, a device may receive, from a first camera, a plurality of images of an airspace corresponding to an area of operation of an unmanned aerial vehicle (UAV). The device may detect, based on the plurality of images from the first camera, a candidate object approaching or within the airspace. Based on detecting the candidate object, the device may control a second camera to direct a field of view of the second camera toward the candidate object. Further, based on images from the second camera captured at a first location and images from at least one other camera captured at a second location, the candidate object may be determined to be an object of interest. In addition, at least one action may be taken based on determining that the candidate object is the object of interest.
