Abstract: Methods and systems for tracking an individual's eye, by tracking one or more ocular axes, are presented.

Abstract: Some embodiments are directed to a system comprising a MEMS based actuator unit and a control electric circuit. The actuator unit comprising one or more MEMS actuators, each comprising a stator and a rotor and configured to define a payload position in response to electric potential between said stator and rotor. The electric circuit comprising one or more amplifiers configured to provide electric control signal to the one or more MEMS actuators to selectively vary position of said payload. The electric circuit comprises a sensing circuit configured for providing an alternating carrier signal and for monitoring said carrier signal to generate data on impedance of said one or more MEMS actuators indicative of position of the rotor with respect to the stator of said one or more MEMS actuators.

Abstract: Geometric-waveform oscillator for processing light, the geometric waveform oscillator including a plurality of masses, at least one force producing element, and a plurality of elastic elements, each of the force producing elements being coupled with a respective one of the masses, at least one of the masses including a light processing module, each of the force producing elements applying a force to the masses, the elastic elements coupling the masses together, the elastic elements coupling the masses with a respective support, wherein the mass values of the masses, the force values of the forces, and the stiffness coefficients of the elastic elements, are selected such that the light processing module oscillates according to the geometric-waveform.

Abstract: A method and system for performing measurements on a test sample with a metrology or inspection tool are disclosed. At least one of the test sample and the tool is moved with respect to the other from a first position to a second position. At the second position, the tool is aligned for measurement of a measurement target on the sample. A focus of the tool on the test sample is adjusted while moving from that first position to the second position.

Abstract: A system configuration for use in testing and/or evaluating a network switching apparatus is set forth. The system configuration includes a network switching apparatus that is to be tested that has a plurality of bidirectional network ports, switch fabric, and a switch fabric control. The switch fabric interconnects the plurality of bidirectional network ports while the switch fabric control directs packet flow through the switch fabric and between the plurality of bidirectional network ports in response to control parameters. A plurality of interconnections facilitate communication of packets between selected pairs of the plurality of ports. The control parameters and the plurality of interconnections are selected to direct packets through each of the plurality of bidirectional network ports for testing using a minimal number of packet generators.
