  • OPTICAL INTERCONNECT IN SPIN-BASED COMPUTATION AND COMMUNICATION SYSTEMS
    Publication number: 20150333839
    Abstract: Techniques are described for data transfer in spin-based systems where digital bit values are represented by magnetization states of magnetoresistive devices rather than voltages or currents. For data transmission, a spin-based signal is converted to an optical signal and transmitted via an optical transport. For data reception, the optical signal is received via the optical transport and converted back to a spin-based signal. Such data transfer may not require an intervening conversion of the spin-based signal to charge-based signal that relies on voltages or currents to represent digital bit values. In addition, techniques are described to use magnetoresistive devices to control the amount of current or voltage that is delivered, where the magnetization state of the magnetoresistive device is set by an optical signal.

  • Method and apparatus for reducing spatial noise of images
    Patent number: 9031353
    Abstract: A method for reducing spatial noise of images includes the following steps. A target pixel is obtained and an operating block is built accordingly. Pixel values of the target pixel and multiple neighboring pixels in the operating block are operated to obtain a variance corresponding to the operating block. Whether the target pixel is characteristic is judged according to the variance. If the target pixel is not characteristic, the multiple pixels in the operating block are filtered to obtain a modulated pixel value. The pixel value of the target pixel is updated to the modulated pixel value.

  • RIGID WAVE PATTERN DESIGN ON CHIP CARRIER SUBSTRATE AND PRINTED CIRCUIT BOARD FOR SEMICONDUCTOR AND ELECTRONIC SUB-SYSTEM PACKAGING
    Publication number: 20150054177
    Abstract: A rigid wave pattern formed on a first side of a substrate in a semiconductor die package. The rigid wave pattern aligns with and overlies the contact fingers formed on the second side of the substrate. The rigid wave pattern includes a first pattern with an etched portion and an unetched portion around the etched portion. When the substrate and dice are encased during the molding process, the rigid wave pattern effectively reduces deformation of and stresses on the dice, therefore substantially alleviating die cracking.
