Abstract: A device may include a memory and a processor. The device may receive, from a ground control station (GCS) associated with an unmanned aerial vehicle (UAV), credentials associated with a user. The device may determine whether the GCS has been registered and determine, in response to determining that the GCS has been registered, whether the UAV has been registered. The device may present, in response to determining that the UAV has been registered, a list of UAVs the user is authorized to operate and receive selection of a particular UAV from the list of UAVs. The device may facilitate operational activities of the particular UAV.

Abstract: A method may include receiving an identifier (ID) from a first unmanned aerial vehicle (UAV) prior to a flight, storing the ID and receiving telemetry information from the first UAV during the flight. The method may also include storing the telemetry information, receiving a request from a user device for information associated with a first location and authenticating the user device. The method may further include determining whether at least one UAV is flying in an area associated with the first location and transmitting telemetry information associated with the at least one UAV, in response to determining that at least one UAV is flying in the area associated with the first location.

Abstract: The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a watersoluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.

Abstract: An unmanned aerial vehicle (UAV) may include a communication interface and a pressure sensor configured to measure barometric pressure. The UAV may also include a processor configured to generate a request for elevation data and barometric pressure data and transmit, via the communication interface, the request to the at least one other device. The processor may also be configured to receive, from each of the at least one other device, elevation data and barometric pressure data, and estimate the elevation of the UAV based on the measured barometric pressure, the received elevation data and the received barometric pressure data.

Abstract: The invention is related to a hydrated silicone hydrogel contact lens having a layered structural configuration: a lower water content silicone hydrogel core (or bulk material) completely covered with a layer of a higher water content hydrogel totally or substantially free of silicone. A hydrated silicone hydrogel contact lens of the invention possesses high oxygen permeability for maintaining the corneal health and a soft, water-rich, lubricious surface for wearing comfort.

Abstract: The invention relates to a soft hydrogel contact lens, especially a silicone hydrogel contact lens, which has a capability of delivering a hydrophobic comfort agent into the eye of a wearer. The hydrophobic comfort agent includes without limitation a monoglyceride, a diglyceride, a triglyceride, a glycolipid, a glyceroglycolipid, a sphingolipid, a sphingo-glycolipid, a phospholipid, a fatty acid, a fatty alcohol, a hydrocarbon having a C12-C28 chain in length, a mineral oil, a silicone oil, or a mixture thereof. It can be released from the soft hydrogel contact lens into the eye of a wearer when being worn so as to strengthen and stabilize the tear film lipid layer and alleviate the dryness of the eye.
