Abstract: A tool, e.g. a downhole tool, utilizes at least one actuator which may be actuated rapidly between positions during operation of the tool. The actuator is moved via flow of an actuating fluid controlled by a main valve which, in turn, is controlled via a pilot valve. The pilot valve is operated to selectively control flow of the actuating fluid to the main valve so as to shift the main valve between desired operational positions.

Abstract: A method for verifying liveness of a finger of a user by capturing a first fingerprint sample from the finger placed on a display by using a first sensor placed under the display. The method may involve transmitting light, by using a first light transmitting display area of the display, towards a first area of the finger. The first light transmitting display area may be smaller than a first sensor area. The first sensor may capture reflected light from the finger. The reflected light may be transmitted through the display. A first feature of the first fingerprint sample may be identified by using the reflected light. The first feature may include scattered light from the finger. The light transmitted from the display may include a first light component with a first wavelength from a first area of the display.

Abstract: A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a2-ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
