Abstract: An unmanned aerial device according to an aspect of the present invention includes an aerial device body capable of flying in an unmanned manner, and a load-lowering device mounted to the aerial device body and configured to lower a load from the aerial device body. The load-lowering device has a linear member holder for holding a linear member having one end portion connectable to the load, the linear member holder holding at least the other end portion of the linear member, and a speed limiting mechanism that limits a speed at which the linear member is pulled out of the linear member holder, under a weight of the load.

Abstract: A reception processing unit receives a user operation performed with respect to an operation tool that causes a work vehicle to execute a predetermined motion. A motion processing unit causes the work vehicle to execute a motion corresponding to the user operation performed with respect to the operation tool. A travel processing unit switches from autonomous travel to manual travel when a change amount relating to the operation tool corresponding to the user operation exceeds a threshold while the work vehicle is performing autonomous travel. A setting processing unit sets the threshold based on at least one of setting information and work information of the work vehicle.

Abstract: A method at a first electronic device with a display and an input device includes: displaying a message input area along with a graphical input stream in a first application, where the graphical input stream includes a source of predefined graphical images and a source for a coded character set. The method includes detecting entry of one or more objects from the graphical input stream into the message input area and receiving a user input to transmit the contents of the message input area. In response to receiving the user input to transmit, and in accordance with a determination that the one or more objects includes a predefined graphical image, the method includes forming a merged message comprising the contents of the message input area, including the predefined graphical image, where a merged message is an image, and transmitting the merged message to a recipient or another application.

Abstract: A first test signal from a test signal source is provided to a spectrum analyzer to produce first measurement data. The test signal source is expressed by a first transfer function G(w) and the spectrum analyzer is expressed by second transfer function F(w). A second test signal is provided to the spectrum analyzer to produce second measurement data where the second test signal is derived from the first test signal by shifting the frequency by a known increment. From the first and second measurement data, the components are the same on G(w) but different on F(w). The G(w) components are cancelled by calculation using the first and second measurement data and then the second transfer function F(w) is evaluated independently of G(w).
