20110002391 | DIGITAL IMAGE COMPRESSION BY RESOLUTION-ADAPTIVE MACROBLOCK CODING - Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” If appropriate, a macroblock is “downsampled” to a lower resolution. The lower-resolution macroblock is then encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted and actual contents of the macroblock. The low-resolution residual is then either transmitted to an image decoder or stored for later use. In some embodiments, the encoder calculates the rate-distortion costs of encoding the original-resolution macroblock and the lower-resolution macroblock and then only encodes the lower-resolution macroblock if its cost is lower. When a decoder receives a lower-resolution residual, it recovers the lower-resolution macroblock using standard prediction techniques. Then, the macroblock is “upsampled” to its original resolution by interpolating the values left out by the encoder. The macroblocks are then joined to form the original digital image. | 01-06-2011 |
20110002554 | DIGITAL IMAGE COMPRESSION BY RESIDUAL DECIMATION - Disclosed is an image encoder that divides a digital image into a set of “macroblocks.” Each macroblock is encoded by applying spatial (and possibly temporal) prediction. The “residual” of the macroblock is calculated as the difference between the predicted content of the macroblock and the actual content of the macroblock. The residual is then “decimated” by taking an orderly subset of its values. The decimated residual is then either transmitted to an image decoder or is stored for later use. To recreate the original image, the macroblocks are first recreated from their received residuals. When a decimated residual is received, the values of the residual left out during decimation are interpolated from the values actually received. Using the prediction techniques along with the residual, the original content of the macroblock is recovered. The macroblocks are then joined to form the original digital image. | 01-06-2011 |

The dominant edge direction may be utilized for the prediction direction, such as in response to a detection mode flag signaled to the decoder, or modified by an angular adjustment, which can be communicated to a decoder. | 10-13-2011 |
20120014443 | DIFFERENTIAL CODING OF INTRA DIRECTIONS (DCIC) - Spatial domain directional intra prediction has been shown to be very effective to remove the correlation between the pixels in the current block and reconstructed neighbors. In AVC, 8 directional prediction modes (plus the DC prediction mode) are defined. The prediction mode number is signaled to the decoder using a simple predictive coding method. The previous intra prediction methods have two major disadvantages: lack of precision for arbitrary directional patterns and accuracy lack of accuracy to exploit geometric dependency between blocks. To address these issues, a new method accurately predicts the intra directions from reconstructed neighboring pixels and differentially encode the intra directions. This allows a more precise directional prediction without the significant increase in the cost for transmitting the side information. | 01-19-2012 |

20150147560 | METHOD FOR ALIGNING HIGH ASPECT RATIO MATERIALS AND COMPOSITIONS THEREFROM - A method for alignment of high aspect ratio materials (HARMs) within a liquid matrix by means of magnetic particles. The application of an external magnetic field creates a forced motion of the magnetic particles. This in turn leads to a laminar flow within the matrix which imposes a drag force on the HARMs, aligning the HARMs across the matrix. The used magnetic particles eventually accumulate at one end side of the matrix container and can be removed either by an incision or an extraction process. Unlike the previously proposed methods, there is no need for the magnetic particles to be attached either physically or chemically to the HARMs. Thus, the ultimate aligned HARMs are mostly pure and free of any magnetic particles. Once the matrix is a polymeric solution, the mentioned method is capable of synthesis of aligned HARMs-polymer composites, which exhibit improved mechanical and electrical properties. | 05-28-2015 |

20160055694 | ACCESS MANAGEMENT AND RESOURCE SHARING SYSTEM BASED ON BIOMETRIC IDENTITY - Disclosed are an apparatus and a method for managing access to a shared resource based on identity that is established by use of biometric data. A biometric locking device (i.e., a “b-lock”) can be used to restrict access to a shared resource, such as a house, a car, etc. In some embodiments, the b-lock can establish an identity of a user based on biometric data obtained by a biometric sensor of the b-lock, and can register the biometric data. After the biometric data is registered, the user can scan, e.g., his finger using the biometric sensor of the b-lock, and the b-lock can verify that the biometric data obtained based on the scan of the finger matches the registered biometric data. Once verified, the b-lock can unlock a locking mechanism of the b-lock to enable the user to access the shared resource. | 02-25-2016 |
20160055695 | ACCESS MANAGEMENT AND RESOURCE SHARING PLATFORM BASED ON BIOMETRIC IDENTITY - Disclosed are an apparatus and method that enables an owner/administrator to manage access to a shared resource based on identity that is established by use of biometric data. For example, access to a shared physical resource can be restricted via use of a biometric locking device. An access management platform can be used to authorize a new user to access the shared resource. Once authorized, the new user can unlock the biometric locking device based on, for example, fingerprint data of his finger. The access management platform can similarly be used to manage access to a virtual shared resource, such as an online account. A virtual locking device, such as a computer that acts as an intermediary between the user and the online account, can be used to restrict access to the online account. The access management platform can enable the user to access the online account based on biometric data. | 02-25-2016 |
