Abstract: A device for harvesting electricity from vibrations of a body that includes a coil with a core that are designed to be fixed to the body, a spring with a suspending magnet attached to its first end in a way that the magnet is positioned close to the core and the second end of the spring is designed to be fixed to the body. The device also includes an electric device that includes a power management circuit that is connected to the coil and an electric energy storing device, and a gap controlling device that is capable to control the distance between the core and the suspending magnet. The vibrations cause the magnet to vibrate relative to the core and to induce electric current in the coil and the energy harvesting can be optimized by controlling the distance between the core and the magnet.

Abstract: An optomechanical device, based on mode coupling, and methods for its use. Two waveguides cross each other and a movable suspended coupler is located at the cross-over, such that on activation, the light propagating in one of the waveguides is coupled into the second waveguide. The coupler may be a third waveguide that upon in-plane deflection, is brought into close proximity or to contact with the sides of the two waveguides. This action creates an optical path by means of the evanescent fields of the two waveguides and the coupling waveguide itself. This basic building block creates a 1 to 1 switching unit that can be scaled up to form non-blocking matrices of ‘n’ input waveguides by ‘m’ output waveguides. Applications for Wavelength Add and Drop Systems, and for Gain Equalizer Systems are described.

Abstract: A neural network, and a method of storing information and retrieving it by such network. The network comprises neurons, synapses and switches, and when required also rectifying means. The network is based on a substance which undergoes a reversible change from stable state A to stable state B, and this substance can also be changed from state A to another state C, which change is also reversible, where each change provides a measurable electrical pulse. The change of state is brought about by means of illumination for a predetermined period of time at a certain wavelength, it being possible to convert a desired part of the substance from one state to the other.
