Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a plurality of shock absorbers provided to the plurality of rotor units; and a main body to which the plurality of rotor units attach. The plurality of rotor units and the plurality of shock absorbers are attachable to and detachable from the main body.
Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a plurality of shock absorbers including a first shock absorber and a second shock absorber different from the first shock absorber, the first shock absorber defining a first gas chamber containing a first gas that is less dense than air; and a release unit that is disposed on the first shock absorber and configured to release the first gas contained in the first gas chamber at a predetermined timing.
Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a balloon that laterally covers the plurality of rotor units, across the height of the plurality of rotor units in the up-and-down direction; a camera that protrudes, along a predetermined axis, beyond the balloon; and a holding component that holds the camera and whose overall length can be shortened along the predetermined axis.
Abstract:
An aircraft includes; a plurality of rotor units each of which includes a propeller and a motor which drives the propeller, and generates thrust for flight of the aircraft; a controller which controls rotation of the propellers included in the plurality of rotor units; a balloon which laterally covers the plurality of rotor units; and a detector which detects a state of the aircraft, wherein the controller decreases a rotational speed of the propeller included in at least one rotor unit among the plurality of rotor units, according to a result of detection by the detector.
Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a bag-shaped body including a chamber; and an injector that injects gas into the chamber to inflate the bag-shaped body. The bag-shaped body covers at least one of the plurality of rotor units when inflated.
Abstract:
The present disclosure provides a method of copying files at a high speed when accesses to both of a local memory physically connected to an access device and a remote memory connected via a wireless network. A file copy controller in the access device generates a FS transfer list in which logical address positions of copy sources and logical address positions of copy destinations are stored, based on file system management information of the local memory and an access list, obtained from another access device, of the remote memory, and inputs the FS transfer list to a non-volatile memory controller connected to the local memory. The non-volatile memory controller copies data between the local memory and the remote memory based on the information stored in the FS transfer list without using a CPU in the access device or an internal bus connected to the CPU.
Abstract:
A recording device operates in accordance with an instruction from an access device. The recording device comprising a nonvolatile memory that stores data, a communication unit that receives an instruction issued by the access device, and a memory controller that controls the nonvolatile memory. When a recording instruction for recording data into the nonvolatile memory is received from the access device, the memory controller starts recording of data into the nonvolatile memory. When the memory controller receives from the access device a suspension instruction for suspending the recording of data, the memory controller stores suspension information into the nonvolatile memory, the suspension information indicating a suspended position as a position in a recording area of the nonvolatile memory at which the data is being recorded upon reception of the suspension instruction.
Abstract:
An aircraft includes: a plurality of rotor units each of which includes a propeller, and a motor which drives the propeller; and a balloon to which the plurality of rotor units are connected and in which a gas less dense than air is contained. At least one rotor unit among the plurality of rotor units generates downward thrust.
Abstract:
An aircraft includes: a plurality of rotor units each including a propeller and a motor that drives the propeller; a balloon that laterally covers the plurality of rotor units, across a height of the plurality of rotor units in an up-and-down direction; and a drive unit configured to change the external shape of the balloon at a predetermined timing.
Abstract:
An aircraft includes: a plurality of rotor units each including propeller and motor that drives propeller; a shock absorber covering an entire vertical length of a lateral side of the plurality of rotor units; and a plurality of rudders each being disposed downstream of a corresponding one of the plurality of rotor units and rotating about axis of rotation that extends in a direction intersecting a flow direction of air current generated by the corresponding one of the plurality of rotor units.
