of the laser beam, and picks up an image of a bright point which is generated on the surface of the work-piece by emission of the pointer light onto the surface; a memory which records distance derivation information for derivation of a working distance; and working distance measuring means ...

This working principle is illustrated in FIGS. 2aand2b. These figures show a power drill as an example of a handheld working tool1equipped with the first embodiment of the positioning system according to the invention. The emitted rotating measurement beam5defines a plane9perpendicular to the dril...
The angle of the detection area is around 110 degree cone. A knob is given to adjust the sensitivity; we can vary from 3 meter to 7 meters perpendicular to senor. The sensitivity reduces as we move either sides of the sensor. Operating Temperature: The HC-SR501 has an impressive operating...
of the intensity field distribution, we present an illumination concept for a super-resolution microscope which allows a three dimensional (3D) optical resolution around 150 nm for working distances up to the centimeter regime. In principle, the system allows great flexibility, because the ...
You might have heard of the popular adage –“If you fail to plan, you plan to fail.”This is so true when it comes to working from home. Work from home can be extremely easy or very challenging, depending on how good you are at planning and prioritizing your work. You will have ...
This same principle was applied to solenoids20. When the wire position coincides with the magnetic axis, the transversal field components cancel out and no motion is induced on the wire. Two wire resonance frequencies are excited for co-and counter-directional movements of the wire stages in the...
This paper reviews current TENG technologies with the sustainable energy generation principle to produce electricity from wasted mechanical energy sources, the surface structure applied to harvest energy and enhance output performance of TENGs, the energy storage system used to store energy for stable elec...
Notice that, both of them depend on a fixed base station with a known position nearby, though the principle of them is quite different. In Oct 2020, when we write this paper, RTK GPS is still an extraordinary expensive approach and usually be used to define the ground truth position of ...
