Abstract: A multi-directional digital camera comprising: a light sensor capable of converting incoming light beams into an electrical signal output representing an imaged scene; one or more multi-mode optical path controlling elements, each having at least two operation modes including (a) a first operation mode in which the multi-mode optical path controlling element reflects the light beams directed thereon, and (b) a second operation mode in which the multi-mode optical path controlling element enables passage of the light beams directed thereon; a controller configured to selectively change the imaged scene by selectively changing an optical path of the light beams, wherein changing the optical path is made by changing the operation modes of one or more of the multi-mode optical path controlling elements.

Abstract: A multi-directional projector includes: a laser source capable of emitting laser beams, a reflective surface capable of reflecting the laser beams emitted by the laser source, wherein the reflective surface is movable by a movement mechanism, for causing the laser beams to reflect to a plurality of directions, a plurality of optical elements, each capable of directing incoming laser beams of the laser beams, being the laser beams directed by the reflective surface when moved by the movement mechanism at the direction of the respective optical element, to a respective projection direction with respect to the laser source, wherein at least two of the optical elements direct the respective incoming laser beams in different projection directions having at least a 90 degrees difference.

Abstract: Mitigation of spectral interference in communications systems such as Digital Subscriber Loop (DSL) systems, and in particular mitigation of spectral interference using dynamic spectral shaping (DSS) in DSL systems, and in particular Single-pair High-speed DSL (SHDSL) systems.

Abstract: A DSL communication system and a method for configuring a DSL communication system. The method includes training at least one anchor DSL modem transmitter to transmit information over at least one anchor line at an anchor bit rate that is determined based on an allowable tolerable noise level and a minimum allowable signal-to-noise ratio (SNR) margin; training one or more other DSL modem transmitter to transmit information over one or more other line at a bit rate that is determined by a current noise level and a target SNR margin, wherein the target SNR margin is higher than the minimum allowable SNR margin; and transmitting information by at least one trained DSL modem transmitter to at least one DSL modem receiver.
