A method of forming an MTJ memory cell and / or an array of such cells is provided wherein each such cell has a small circular horizontal cross-section of 1.0 microns or less in diameter and wherein the ferromagnetic free layer of each such cell has a magnetic anisotropy produced by a magnetic coupling with a thin antiferromagnetic layer that is formed on the free layer. The MTJ memory cell so provided is far less sensitive to shape irregularities and edge defects than cells of the prior art.

An MTJ element is formed between orthogonal word and bit lines. The bit line is a composite line which includes a high conductivity layer and a soft magnetic layer under the high conductivity layer. During operation, the soft magnetic layer concentrates the magnetic field of the current and, due to its proximity to the free layer, it magnetically couples with the free layer in the MTJ. This coupling provides thermal stability to the free layer magnetization and ease of switching and the coupling may be further enhanced by inducing a shape or crystalline anisotropy into the free layer during formation.

Methods and devices to treat discogenic lumbar back pain are disclosed. Electrodes are implanted within the anterior epidural space of the patient. A pulse generator that is connected to the electrodes delivers electrical impulses to sympathetic nerves located within the posterior longitudinal ligament (PLL) of the lumbar spine and outer posterior annulus fibrosus of the intervertebral disc.

An MTJ MRAM cell element, whose free layer has a shape induced magnetic anisotropy, is formed between orthogonal word and bit lines. The bit line is a composite line which includes a high conductivity current carrying layer and a soft adjacent magnetic layer (SAL). During operation, the soft magnetic layer concentrates the magnetic field of the current and, due to its proximity to the free layer, it magnetically couples with the free layer to produce two magnetization states of greater and lesser stability. During switching, the layer is first placed in the less stable state by a word line current, so that a small bit line current can switch its magnetization direction. After switching, the state reverts to its more stable form as a result of magnetostatic interaction with the SAL, which prevents it from being accidentally rewritten when it is not actually selected and also provides stability against thermal agitation.

An MTJ MRAM cell is formed above or below an intersection of vertically separated, magnetically clad, ultra-thin orthogonal word and bit lines whose thickness is less than 100 nm. Lines of this thickness produce switching magnetic fields at the cell free layer that are enhanced by a factor of approximately two for a given current. The word and bit lines also include a soft magnetic layer of high permeability formed on their surfaces distal from the cell to improve the magnetic field still further. The fabrication of a cell with such thin lines is actually simplified as a result of the thinner depositions and eliminates the necessity of removing material by CMP during patterning and polishing, thereby producing uniform spacing between the lines and the cell free layer.

In telecommunication video calling and videoconferencing systems, it is strongly desirable for remote observers to interact with natural gaze cues. In natural gaze interaction, the camera for a source observer appears to be co-located in the eye region of a destination observer image and vice versa. The appearance of camera co-location is achieved for stereoscopic camera pair that are placed either side of an autostereoscopic 3D display. Such cameras typically provide stereoscopic images that have disparity distributions that provide unnatural perceived head roundness. The present embodiments achieve perceived head roundness that is closer to that expected in natural face to face interaction by modification of perceived local depth in detected regions of the head.

A large-area projector screen, whose joining gaps are inconspicuous, and a method of producing the screen are provided. The screen according to the present invention is produced by arranging and bonding a surface diffusion sheet having a predetermined haze value and approximately isotropically diffuses incoming light and multiple directional diffusion sheets together. Here, the directional diffusion sheets have a large scattering effect with respect to light incident at a predetermined angle and have a small scattering effect with respect to light incident from other directions. As a result, even when a large screen is formed using a directional scattering sheet divided into multiple regions, boundaries between the divided regions become difficult to visually recognize due to a diffusion action of the surface diffusion sheet and more natural image projection becomes possible.

Amplitudes of signals produced by a digital modulator can be clipped so that instead of processing the output vector of the digital modulator or it's component vectors, processing is applied to the base band I and Q signals prior to modulation. The I- and Q signals are applied to an input of a clipping circuit. Predetermined limit values are also applied to another input of the clipping circuit. The clipping circuit rotates on the I-Q vector towards the limit vector. At the same time the limit vector is rotated towards the I-Q vector. Rotations are performed by using Cordic algorithm. After rotations have been completed, the rotated I-Q vector is aligned with the original limit vector, and the rotated limit is aligned with the original I-Q vector. Then the length of the rotated I-Q vector will be compared with the original limit vector. If the rotated I-Q vector is shorter than the limit vector, then the original I-Q signals are output signals from the clipping circuit. But if the rotated original I-Q vector is longer than the limit vector, then the original I-Q signals will be rejected and substituted by the coordinate values of the rotated limit vector.
