Abstract: A band latch mechanism that is configured to connect a wristband to a fitness tracker is provided. The band latch mechanism may be configured to be inserted into a cavity of a housing of the fitness tracker and configured so that any metallic body of the band latch mechanism does not contact metallic surfaces of the cavity in order to prevent an electrical ground from being positioned within a keep-out zone of an antenna of the fitness tracker.

Abstract: A wastewater monitoring system uses a camera in a fixed location in a wastewater pipe. The camera is coupled to a sensor that measures some characteristic of material in the wastewater pipe. The sensor is programmed with one or more alarms that, when triggered, cause the sensor to wake up the camera and command the camera to take one or more photos. Sensor data, such as current time/date, location, and the characteristics of material in the wastewater pipe, is sent by the sensor to the camera, which overlays one or more photos with visible text information corresponding to the received sensor data. The sensor can wake up the camera and command the camera to turn on the camera's Wi-Fi interface, which allows a wastewater control system in a remote location to communicate directly with the camera.

Abstract: An eyewear system having a lens and a nasion pad is disclosed. The nasion pad is configured to fit on a user's nasion and at least partially secure the eyewear in position. In one embodiment, the nasion pad has a saddle shape to prevent movement or rotation of the eyewear with respect to the user's face. A nose contact is coupled to the nasion pad. The nose contact can have a channel adapted to receive a leg extending from the lens. The lens is coupled to a retractor which provides a force to pull the lens toward the user's face. The eyewear system can be coupled to a helmet or hard hat. The lens is moveable between a first position on the user's face and a second position on the hard hat. The eyewear can be frameless and the retractor can be coupled to an engagement feature on the lens.

Abstract: An electrochemical reactor for use with a liquid electrolyte is capable of generating gaseous products. An electrically conducting porous layer that is hydrophilic on the catalyst side and hydrophobic on the gas side are utilized. These different surface properties promote the transport of product gases formed at the catalyst through the porous layer to the gas side. The catalyst is formed from a hybrid Cu2O—CuBr film that has a high selectivity for ethylene gas from reacting CO2 and water in an electrochemical cell.

Abstract: The present disclosure relates to nanocomposites of CuO/Cu2O and continuous flow solar reactors. The nanocomposites can be utilized as a photocatalyst and can be incorporated into photoelectrochemical devices. The described devices, systems, and methods can be used for converting CO2 into one or more alcohols and other small organics with the use of solar energy and electricity. Other embodiments are described.
