| 20090262864 | SYMMETRICAL DATA SIGNAL PROCESSING - In a digital communications receiver configured to receive, via a communications channel, a received first signal representing a sequence of symbols, each symbol being encoded to be representative of data bits, a method of processing the received signal includes adjusting a magnitude, filtering, and applying cyclic prefix restoration, to the received signal to produce a second signal, converting the second signal from time domain to frequency domain to produce a frequency domain signal, and determining a first quantity of values representing a first portion of the symbols by evaluating a relationship of channel values representing characteristics of the communications channel and a second quantity of values representing a portion of the frequency domain signal, the first quantity being smaller than the second quantity. | 10-22-2009 |
| 20100246733 | TRELLIS DECODER FOR DECODING DATA STREAM INCLUDING SYMBOLS CODED WITH MULTIPLE CONVOLUTIONAL CODES - A trellis decoder decodes a stream of encoded symbols, including symbols of a first type (e.g. symbols encoded with a first trellis code) and symbols of a second type (e.g. encoded with a second, more robust, trellis code), without storing path indicators along a trellis for symbols of the first type. In this way, limited memory may be used to store path indicators along the trellis for symbols of the second type. This allows for more accurate decoding of the symbols of the second type. For transitions from symbols of the second type to symbols of the first type, states of the trellis decoder may be stored. In this way, paths may be traced back along the trellis for trellis decoding, without the path indicators for the symbols of the first type. | 09-30-2010 |

| 20090064476 | PIEZOELECTRIC MATERIALS BASED ON FLEXOELECTRIC CHARGE SEPARATION AND THEIR FABRICATION - An example flexoelectric piezoelectric material has a piezoelectric response, which may be a direct piezoelectric effect, a converse piezoelectric effect, both effects, or only one effect. A flexoelectric piezoelectric material comprises shaped elements of a material, which may be a substantially isotropic and centrosymmetric material. The shaped elements, such as cones, pyramids, wedges, or other tapered elements, may provide an electrical response in response to stress or strain gradients due to a flexoelectric effect in the material, and may provide a mechanical response in response to electric field gradients. Examples of the present invention include improved methods of fabricating devices comprising such shaped elements, and multi-layer devices having improved properties. | 03-12-2009 |
| 20110006641 | FLEXOELECTRIC - PIEZOELECTRIC COMPOSITE BASED ON FLEXOELECTRIC CHARGE SEPARATION - An example flexoelectric-piezoelectric apparatus provides an electrical response to an applied force, and/or an actuation in response to an applied electric field, that originates from the flexoelectric properties of a component. For example, shaped forms within the apparatus may be configured to yield a stress gradient on application of the force, and the stress gradient induces the flexoelectric signal. A flexoelectric-piezoelectric apparatus can be substituted for a conventional piezoelectric apparatus, but does not require the use of a piezoelectric material. Instead, the response of the apparatus is due to the generation of stress gradients and/or field gradients. | 01-13-2011 |

| 20110008369 | PD-1 BINDING PROTEINS - The present invention features PD-1 binding proteins, a subset of which inhibits binding of PD-L1 to the PD-1 receptor. These binding proteins can be employed to modulate the immune system through the manipulation of the PD-1 signaling pathway, enhancing host immunity to treat infections and cancer. | 01-13-2011 |
| 20110136896 | VARIANT HCMV PP65, IE1, AND IE2 POLYNUCLEOTIDES AND USES THEREOF - The present invention relates to compositions and methods to elicit or enhance cell-mediated immunity against HCMV infection by providing polynucleotides encoding variant HCMV pp65, IE1, and IE2 proteins, and fusion proteins thereof. The present invention also provides recombinant vectors including, but not limited to, adenovirus and plasmid vectors comprising said polynucleotides and host cells comprising said recombinant vectors. Also provided herein are purified forms of the variant HCMV pp65, IE1, and IE2 proteins described herein, and fusion proteins. The variant HCMV proteins, and fusion proteins thereof, are useful as vaccines for the protection from and/or treatment of HCMV infection. Said vaccines are useful as a monotherapy or a part of a therapeutic regime, said regime comprising administration of a second vaccine such as a polynucleotide, cell-based, protein or peptide-based vaccine. | 06-09-2011 |
