Abstract: A system for determining the authenticity of an object including a reference-image acquisition module for acquiring a reference-image. The reference-image acquisition module includes a light-source, an imager including an imaging-sensor, and a database coupled with the imager for storing the reference-image. The light-source directs circumferential-light toward an authentication-region on the object. The circumferential-light is at least one of collimated and telecentric. The circumferential-light impinges on the authentication-region from a plurality of different azimuthal directions and at a predetermined oblique angle relative to the normal of a plane defined by said object. A portion of the circumferential-light is reflected from the authentication-region toward a specular reflection region and another portion is scattered from the authentication-region. The imager is focused on the authentication-region and acquires a reference-image. The reference-image is a focused image of the scattered light. The reference-image includes image features related to surface features scattering phenomena of the authentication-region.

Abstract: A drone control system for controlling a drone which includes an onboard-flight-system previously configured to receive navigational-data in a format compliant with a standard navigational data transmission protocol. The system includes a remote-sensor and an interface. The remote sensor is located remotely from the drone and determines the position of the drone relative to the remote-sensor. The interface, coupled with the remote-sensor, produces a pseudo GPS signal indicating the position of the drone and to provide the pseudo GPS signal to an onboard-flight-system of the drone. The format of the pseudo GPS signal is fully compliant with the standard navigational data transmission protocol employed by the onboard-flight-system. The onboard-flight-system is receives inertial tracking data from an onboard inertial-measuring-unit and the pseudo GPS signal, and tracks the position of the drone by merging the inertial tracking data and the pseudo GPS signal and navigates the drone accordingly.

Abstract: An electric double-layer capacitor (EDLC) and method for manufacturing thereof. The ELDC includes at least one capacitor cell with two parallel current collectors, two opposite polarity electrodes, a separator, a rigid dielectric frame, and at least one evacuation mechanism. Each electrode is disposed on a respective current collector, and impregnated with aqueous electrolyte. The frame is disposed along the perimeter on the surface of a current collector and enclosing the electrodes. The evacuation mechanism removes superfluous fluid material from the capacitor cell interior. The evacuation mechanism may be a compartment in the frame, operative to collect residual electrolyte that seeps out from the electrodes, or a capillary formed within the frame and extending into a portion of the electrode, the capillary composed of a porous hydrophobic material and operative to evacuate discharged gases from the electrodes out of the EDLC.

Abstract: An optical seismic surveying system including, a multibeam laser source including a plurality of laser-sources, a Diffractive-Optical-Element (DOE), an imager and a processor. The laser-sources direct respective laser-beams toward a single common focal point. The DOE is located at a single common focal point and configured to split each laser-beam into a plurality of laser-beams, toward an instantaneous area of interest. The laser-beams impinging on the instantaneous area of interest produce a laser spot assemblage including a plurality of laser spots. The imager acquires a plurality of defocused images of speckle patterns produced by diffused reflections of the laser spots. The speckle pattern correspond to a respective laser spot and thus to a respective sensing point in the instantaneous area of interest. The processor determines a relative displacement between corresponding speckle patterns in sequential pairs of images and determines a respective time-signal for each sensing point representing vibrations thereat.

Abstract: A method and circuit for providing adaptive suppression of signal crosstalk appearing on a common return wire in a signal cable connected to a device. The method steps comprise connecting an adjustable negative resistance circuit between the common wire terminal and a common point at the device; determining an auxiliary current (Iaux) such that is flowing through at least one of the cable wires and returns through the common wire; sensing the voltage between selected at least one of the cable wire terminals at the device port and the common point, while ensuring that this level is substantially affected by Iaux; measuring a level of the sensed voltage according to a predefined level measurement procedure; and adjusting the negative resistance so as to nullify said voltage level, thereby effectively cancelling the common wire ohmic resistance.

Abstract: An impulse radio (IR) ultra-wide band (UWB) transceiver adapted for a rake receiver is provided herein. This may be implemented as follows: on the transmitter side, the input data is converted to N-parallel streams having different delays, each stream is transmitted by an impulse radio signal with defined different carrier frequency. On the receiver side, the multicarrier RF signal is converted into base band signal, emulating multipath channels, so that rake receiver technique is used for an optimal demodulation of the received signal.
