20110017651 | VERTICAL DESALINATION ELEMENT - A vertical desalination element comprising a vertical pressure vessel (PV), membrane elements, and a loading mechanism for loading the membrane elements into the vertical PV. The vertical arrangement of the membrane elements and the vertical PV enhances air bubble percolation, increases construction efficiency and allow handling heavy membrane elements. The membrane elements may be loaded singly or groupwise, from either the upper or the lower end of the vertical PV. The loading mechanism may comprise various appliances and devices for supporting and securing the membrane elements, and may apply various ways of loading and releasing the membrane elements. | 01-27-2011 |

20090113214 | SOFTWARE PROTECTION AGAINST FAULT ATTACKS - A method for protecting information in a device includes providing a device with a non-secure hardware domain, a processor having a software-controlled mode of operation, and a secure hardware domain having a secure memory that is inaccessible by the processor when the processor is operating in the software-controlled mode of operation. Data from the non-secure hardware domain is established in the secure hardware domain. Computing operations are executed on the data in the secure hardware domain to produce a result. The secure hardware domain is purged, while retaining the result therein. The result is thereafter returned from the secure hardware domain into the non-secure hardware domain. | 04-30-2009 |

20090116096 | All Optical System and Method for Providing Extended Depth of Focus of Imaging - An imaging system and method are presented. The system comprises an imaging lens unit, an imaging detector, and a birefringent element located between the imaging lens unit and the imaging detector. The system is thus configure and operable to provide in-focus imaging of objects located at both near-field and far-field ranges. Also provided is an optical device configured to be mounted on an imaging lens, being one of the following: a lens of an individual's glasses, on a contact lens, and an eye internal lens. The optical device is configured to be located between the imaging lens and the retina and comprises a birefringent element, to thereby provide in-focus imaging onto the retina of the objects located at both near-field and far-field ranges therefrom. | 05-07-2009 |
20130033676 | IMAGING SYSTEM WITH OPTIMIZED EXTENDED DEPTH OF FOCUS - An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing. | 02-07-2013 |
20130044289 | IMAGING WITH EXTENDED DEPTH OF FOCUS FOR USE WITH POLYCHROMATIC LIGHT - An imaging lens unit is presented, comprising an imaging lens having a lens region defining an effective aperture, and a phase coder. The phase coder may be incorporated with or located close to the lens region. The phase coder defines a surface relief along the lens region formed by at least three phase patterns extending along the lens region. Each of the phase patterns differently affecting light components of one of at least three different wavelength ranges while substantially not affecting propagation of light components of other of said at least three wavelength ranges. The surface relief affects light propagation through the lens region to extend a depth of focus for at least one of said at least three wavelength ranges. | 02-21-2013 |
20130046381 | MULTI-FOCAL LENS - An imaging lens structure and method of imaging are presented. The imaging lens structure comprising a lens region defining an effective aperture of the lens structure. The lens region comprises an arrangement of lens zones distributed within the lens region and comprising zones of at least two different optical functions differently affecting light passing therethrough. The zones of at least two different optical functions are arranged in an interlaced fashion along said lens region corresponding to a surface relief of the lens region such that adjacent lens zones of different optical functions are spaced apart from one another along an optical axis of the lens structure a distance larger than a coherence length of light at least one spectral range for which said lens structure is designed. | 02-21-2013 |
