A tethered unmanned aerial vehicle (“UAV”) may be outfitted with a sensor payload for data gathering. The tethered UAV may be tethered to a ground station for constricting the flight space of the UAV while also providing the option for power delivery and/or bidirectional communications. The tethered UAV's flight path may be extended by introducing one or more secondary UAVs that cooperate to extend the horizontal flight path of a primary UAV. The ground station, which may be coupled with the tethered aerial vehicle, may comprise a listening switch configured to determine a condition of the tether such that the supply of power to the tether may be terminated when tether damage or a tether severance is detected.

In a method for controlling an unmanned aerial vehicle (UAV) in a flight space using a computing device, at least one camera is installed in the flight space. The method sets a flight area of the UAV in the flight space, and stores geographic information of the flight area into a storage device. The method further controls each of the camera to capture a series of 3D images from the flight space, analyzes a current location of the UAV in the flight space according to the 3D images, and compares the current location with the geographic information of the flight area to determine whether the UAV flies out of the flight area. In addition, the method sends a warning message to a remote controller when the UAV flies out of the flight area, and controls the UAV to fly within the flight area using the remote controller.

In the mass spectrometer of the present invention, a flight space is provided before the mass analyzer, and the flight space includes a loop orbit on which ions fly repeatedly. While ions fly on the loop orbit repeatedly, ion selecting electrodes placed on the loop orbit selects object ions having a specific mass to charge ratio in such a manner that, for a limited time period when the object ions are flying through the ion selecting electrodes, an appropriate voltage is applied to the ion selecting electrodes to make them continue to fly on the loop orbit, but otherwise to make or let other ions deflect from the loop orbit. If ions having various mass to charge ratios are introduced in the loop orbit almost at the same time, the object ions having the same mass to charge ratio continue to fly on the loop orbit in a band, but ions having mass to charge ratios different from that are separated from the object ions while flying on the loop orbit repeatedly. Even if the difference in the mass to charge ratio is small, the separation becomes large when the number of turns of the flight becomes large. After such a separation is adequately achieved, the ion selecting electrodes can select the object ions with high selectivity, or at high mass resolution. By adding dissociating means, fragment ions originated only from the selected object ions can be analyzed, which enables the identification and structural analysis of the sample at high accuracy.

In a time of flight mass spectrometer (TOFMS) having a flight space in which ions fly in a loop orbit formed by a plurality of electric sector fields, the present invention provides a simple structure that creates a spiral path by deflecting the ions in the axial direction of the electric fields at every turn of the ions. In a mode of the present invention, the TOFMS has cylindrical electrodes 11 and 12 for creating electric sector fields E1 and E2, between which a parallel pair of planer magnetic poles 15a and 15b are provided.

There is no need to provide one deflector for each turn of the ions, as in the case of conventional TOFMSs.

A thin metal plate (113) and two rectangular rod-shaped metal members (112) that are parallel to each other are alternately superposed repeatedly, and thick metal plates (111) are disposed on both ends of the stack to sandwich the stack. Each surface which is in contact with another surface is bonded thereto by diffusion bonding to form an integrated multilayer structure (110). The multilayer structure (110) is cut at given intervals along planes perpendicular to the thin metal plates (113). Thus, a grid-shaped electrode (100) which has spaces, as openings (102), formed by thin metal plates (113) serving as blades (101) and by metal members (112) as spacers is obtained. With this configuration, it is possible to increase the thickness of the blades (101) to heighten the mechanical strength while keeping the width of the blades (101) and the distance therebetween small. Furthermore, leakage of an electric field from the flight space side to the ion acceleration region side can be inhibited, and the ions which are being introduced can hence be prevented from escaping from the ion acceleration region to the flight space side.
