Abstract: This disclosure describes a system and method for operating an automated aerial vehicle wherein the battery life may be extended by performing one or more electricity generation procedures on the way to a destination (e.g., a delivery location for an item). In various implementations, the electricity generation procedure may include utilizing an airflow to rotate one or more of the propellers of the automated aerial vehicle so that the associated propeller motors will generate electricity (e.g., which can be utilized to recharge the battery, power one or more sensors of the automated aerial vehicle, etc.). In various implementations, the airflow may consist of a wind, or may be created by the kinetic energy of the automated aerial vehicle as it moves through the air (e.g., as part of a normal flight path and/or as part of an aerial maneuver).

Abstract: A troffer door assembly has a frame assembly, a lens member and a light emitting diode (LED) assembly. The rigid brace member is affixed to the frame assembly such that the rigidity of the frame assembly is increased. Hinge members and latch members are positioned in exterior slots on the frame assembly such that the location of the hinge members and latch members can be adjusted. In this manner installed troffer light fixtures can be retrofitted by replacing the installed troffer door with the troffer door assembly as described.

Abstract: Unmanned aerial vehicles (“UAVs”) which fly to destinations (e.g., for delivering items) may land on transportation vehicles (e.g., delivery trucks, etc.) for temporary transport. An agreement with the owner of the transportation vehicles (e.g., a shipping carrier) may be made for obtaining consent and determining compensation for landings, and the associated transportation vehicles that are available for landings may be identified by markers on the roof or other identification techniques. The routes of the transportation vehicles may be known and utilized to determine locations where UAVs will land on and take off from the transportation vehicles, and in cases of emergencies (e.g., due to low batteries, mechanical issues, etc.) the UAVs may land on the transportation vehicles for later retrieval.

Abstract: This disclosure describes a system and method for operating an automated aerial vehicle wherein influences of a ground effect may be utilized for sensing the ground or other surfaces. In various implementations, an operating parameter of the automated aerial vehicle may be monitored to determine when a ground effect is influencing the parameter, which correspondingly indicates a proximity to a surface (e.g., the ground). In various implementations, the ground effect based sensing techniques may be utilized for determining a proximity to the ground, as a backup for a primary sensor system, for determining if a landing location is uneven, etc.

Abstract: A light fixture is configured for use in either retrofitting an existing troffer light fixture or for use in new construction. The light fixture includes a self-supporting adaptor bracket configured to rest on a T-bar of a ceiling system and further configured to optionally receive a housing of the existing troffer light fixture. The light fixture further includes a door assembly including a latch configured to engage a latch surface of the adaptor bracket, a hinge configured to interface with a slot of the adaptor bracket, a housing including the latch and the hinge, and a light source within the housing.
