A crane cart can be used to raise and lower the room conditioning unit via a lifting apparatus configured to attach to the anchor points such that a lift attachment point of the lifting apparatus is located above the center of mass of the room conditioning unit. Telescopic closeout panels can seal gaps between the room conditioning unit and the sides of the corresponding window. A mounting pad system having a mounting pad and an actuator can extend and retract to contact a wall and secure the room conditioning unit in place.

Abstract: A physical access control system enables acceptable portal entry codes upon receiving each physical access request by operating on the elapsed time from a previous physical access request to generate a temporal credential. The controller receives a plurality of physical access requests from a plurality of mobile application devices. Upon authenticating the first access request, the controller eliminates repetition from the space of acceptable successor requests from each mobile application device. Monotonic nonces advance the range of temporal code matches. Entry code generation is decentralized to distributed application devices and is inherently unknowable until a successor access request is initiated by the same application device.

Abstract: Embodiments include devices and methods for managing network communication of an unmanned autonomous vehicle (UAV). A processor of the UAV may determine an altitude of the UAV. The processor may optionally also determine a speed or vector of the UAV. Based on the determined altitude and/or speed/vector of the UAV, the processor may adjust the communication parameter of the communication link between the UAV and a communication network. The processor may transmit signals based on the adjusted communication parameter, which may reduce radio frequency interference caused by the transmissions of the UAV with the communication network.

Abstract: A lighting system for an unmanned autonomous vehicle (UAV) adapts to the environment around the UAV to ensure status notification lights are visible to an operator and/or abide by regulatory lighting requirements. A processor of the UAV may receive information from various sensors regarding environmental conditions and location of the UAV, and adjust a UAV lighting system to ensure visibility under the environmental conditions. Adjustments to the lighting system may include selection of light sources that are illuminated, the illumination intensity of particular light sources, the colors emitted by various light sources and other lighting configurations.

Abstract: Various embodiments involve dynamically controlling parameters for processing sensor data, including rates at which vehicle sensors are sampled and analyzed, based on the vehicle's speed and direction. Data or sampling rates of sensors useful for collision avoidance and/or path planning may be adjusted to emphasize data from sensors having a field of view encompassing the travel direction, while limiting processing of data from sensors less likely to provide useful data for such purposes. In some embodiments, the rate at which data from a particular sensor is sampled and/or processed may depend on a vehicle's direction and speed of travel as well as the sensor's field of view. Processing demands may be reduced by focusing processing on data from sensors viewing the direction of travel while reducing processing of data from sensors viewing other directions. In some embodiments, sensor data sampling or processing rates may vary based on collision risk probabilities.
