A system including a drone device comprising securable compartments, each of the securable compartments lockable and configured to be unlocked by a user or a remote device is provided. The system also includes a series of sensors provided with the drone device and configured to assess health attributes of the user while the drone is positioned proximate the user and a remote computing system configured to receive sensed information from the drone device and assess health of the user, wherein the remote computing system holographically displays health attributes of the user. The drone device travels to the user to provide or receive healthcare related objects to or from the user. The series of sensors comprise at least one audio sensor and at least one video sensor configured to assess user health attributes about the user's body in a contactless manner based on both audio and visual health attribute readings.

Disclosed is a suspended system with orientation control including a planar frame, a plurality of sensors coupled to the frame and configured to track an orientation of the frame in real time and at least two thrusters coupled to the frame and configured to adjust the orientation of the frame. Each of the at least two thrusters may have an axis oriented in a direction perpendicular to the frame and two propellers axially aligned with the axis and configured to rotate in a same direction while creating thrust in opposite directions. A holographic fan configured to display a graphic may be coupled to the frame. The planar frame may be suspended from an unmanned aerial vehicle.

In a general aspect, a device for attaching a towed device to an aircraft in flight can include an attachment cable secured to the towed device. The attachment cable can have one end forming a closed loop and including a loop head. The device can also include a first attachment element secured to the loop head of the attachment cable, The first attachment element can include first electrical connectors. The device can further include a towing cable attached to the aircraft and a second attachment element attached to one end of the towing cable. The second attachment element can be configured to cooperate mechanically and electrically with the first attachment element. The second attachment element can include second electrical connectors configured to cooperate with the first electrical connectors. The device can still further include fasteners or guides configured to hold the loop head of the attachment cable off the ground.

In a general aspect, an airborne geophysical prospection device can include a support structure having a surface area of several hundred square meters and an electromagnetic antenna disposed on the support structure. The electromagnetic antenna can have a surface area of several hundred square meters. The electromagnetic antenna can include one or more loops disposed on the support structure. The support structure can be configured to be towed behind an aircraft with a towing cable. The support structure can be supple, deployable under traction and substantially planar after deployment.
