Abstract: A photonic circuit can include a multi-waveguide edge coupler to receive light from an external light source. The edge coupler can include planar waveguides and one or more middle waveguides that separate the planar waveguides. The middle waveguides can couple light and have a tapered shape. The planar waveguides can include multiple thin plates that have sub-wavelength thickness, and can be implemented to shape a mode coupled between an external light source and the photonic circuit.

Abstract: A shopping cart sanitization device, including a main body to receive at a first end at least one shopping cart therein, and a primary sanitization unit disposed within at least at least one portion of an interior of the main body, the primary sanitization unit including a sanitization body to automatically move from a second end of the main body to the first end of the main body in response to the main body receiving the at least one shopping cart, and at least one illumination unit disposed on at least at least one portion of the sanitization body to automatically illuminate UV light on the at least one shopping cart in response to the main body receiving the at least one shopping cart, such that the at least one illumination unit eliminates a pathogen.

Abstract: A shopping cart sanitization device, including a main body to receive at least one shopping cart therein, and a plurality of sanitization units, each of the plurality of sanitization units including a top illumination unit disposed on at least a portion of a top of the main body to illuminate a first UV light on the at least one shopping cart from above, such that the top illumination unit is oriented toward a ground surface, a first side illumination unit disposed on at least a portion of a first side of the main body to illuminate a second UV light on a first side of the at least one shopping cart, and a second side illumination unit disposed on at least a portion of a second side of the main body opposite with respect to the first side to illuminate a third UV light on a second side of the at least one shopping cart.

Abstract: Disclosed are various embodiment of a vehicle rescue system. The vehicle rescue system may include a gas chamber that is attached to a vehicle, the gas chamber comprising an enclosed cavity; a gas tube that is connected to the gas chamber, the gas tube being filled with a gas; and an inflation control module attached to the gas chamber, the inflation control module being configured to control a release of the gas from the gas tube into the gas chamber, wherein releasing the gas inflates the gas chamber.
