Variable optical attenuators (VOAs) are provided, based on electrically switchable CLC reflective polarizers. The reflectivity of the described reflective VOAs can theoretically be electrically adjusted between 0% to 100%, and the reflective bandwidth can be easily adjusted. In general, the VOA includes a pair of switchable CLC polarizers and a driver for driving the polarizers. When the electric fields on both polarizers are off, the polarizers serve as two reflective mirrors. When the fields are turned on, the two polarizers are switched into two transparent sheets allowing light to transmit therethrough. Continuously changing the voltages on the two polarizers electrically adjusts the attenuation.

In order to achieve food and energy security, while at the same time eliminating the “food vs. biofuel” conflict, a transformational three dimensional multilayer farming, MLF, is presented. This exploits the third dimension. This goal is realizable by the disclosed means and methods to increase the 3D plant productivity, 3D yield, ton/m3/year, using ultra-compact ultra high density vertical structures. Each layer in the MLF system comprises at least one string of SanSSoil Growth Elements, SGEs, each designed to carry out multiple functions essential to sustain plant growth, and constructed in a manner to integrate these functions at low-cost. The networked strings of SGEs in each layer provide near self-sufficiency for growth, and in an integrated MLF system, achieve maximum vertical compactness and highest growth density. The multi-functions of each integrally made SGE include: germination, growth sustenance, localized delivery of nutrients, environment sensing, and localized delivery of illumination.

A line blanker system for converting a stereoscopic image into a line-blanked stereoscopic image suitable for stereoscopic viewing on a standard non-interleaved display device is provided. The system includes a method for controlling the line blanker. According to the invention, one can enable and disable the line blanker, identify the first line of the image being processed and determine whether the first line is for viewing by the left eye or the right eye of a viewer. In addition, the invention includes a line doubler. The line doubler provides enhanced brightness and resolution by replacing the blanked line with a double of the line immediately adjacent to the blanked line.

A method for fabricating multi layer devices on a substrate with a buried oxide layer is disclosed. Multi layer microelectromechanical, microfluidic, and integrated circuit devices are fabricated on a substrate with layers of predetermined weak and strong bond regions with deconstructed layers of devices at or on the weak bond regions. The layers are then peeled and subsequently bonded to produce a multi layer microelectromechanical and microfluidic devices. An arbitrary number of layers can be bonded and stacked to create either microelectromechanical or microfluidic device or a hyrbid type of device.

A reconfigurable backlighting construction for use in portable computer-based systems having direct and projection viewing modes of operation is provided. These computer-based systems are capable of selectively displaying color video images on an actively driven display surface, or projecting such video images onto a wall surface or projection screen without the need for a bulky overhead projector, required by all prior art systems. These computer-based systems can be easily reconfigured for projection viewing without physical removal of the light guiding panel and its light diffusing structures. A portable light projection accessory device is also provided for use with the portable computer-based systems of the present invention. The portable light projection device has first and second housing portions that are interconnected by a foldable structure that permits the first and second housing portions to be selectively reconfigured for simple trouble-free use during the projection viewing mode of operation, and for compact storage during the direct viewing mode of operation.
