Abstract: Provided are apparatuses and methods using an optical speckle. An apparatus may include a light source configured to emit coherent light to an object and an imaging device configured to photograph a speckle pattern generated on the object by the coherent light. The apparatus may also include a processor having a function of determining whether the object is a living body or a non-living body by measuring a contrast of the speckle pattern. The processor may be configured to determine whether the object is a living body or not by comparing the contrast of the speckle pattern with a threshold contrast or a reference contrast previously registered by a user. The apparatus may be used by being applied to a fingerprint recognition system.

The method includes selecting, a sensor distribution pattern for a geographical region and determining a location for a base station. A plurality of sensor clusters are generated, each sensor cluster being formed by one of a first and second grouping mechanism. Further, the method allocates, for each sensor a time-slot within a time-frame to transmit a data packet from the sensor to the base station, and evaluates the performance of the first grouping mechanism and the second grouping mechanism for the selected sensor distribution pattern and base station location, by computing at least a ratio of delivered data packets to the base station to a total energy consumption, and a first delay and a second delay incurred by each data packet.

Abstract: Discussed herein are a sensor-network system and a method thereof for detecting and isolating faults occurring in sub-systems and sensors included in the network. The sub-systems and the sensor measurements are subject to noise and disturbances. A bank of Kalman-filters (KF) is used to detect and isolate the faults. Each KF is driven by either a pair of consecutive sensor measurements or a pair including a reference input and a sensor measurement. The KF residual is computed for each measurement pair and is a reliable indicator of a fault in subsystems and sensors located in the network.

Abstract: A waterborne shape memory polymer coating that gives textiles and fibers good shape memory performance. An amphiphilic, crosslinkable grafted polysaccharide polymer was synthesized and provided in a water dispersion that can be applied to a flexible fibrous material and then crosslinked to yield good shape memory properties. The polymer coating showed good binding to human hair, which could be styled into a permanent shape (e.g., straight) during the crosslinked step. Next, this permanent shape can be styled to a temporary shape (e.g. curly) by heating and styling, and cooling. Finally, the permanent style can be regained by activation with water, heat, or both.
