Abstract: A thermal interface material provides thermal conduction or thermal dissipation across an interface, using a three-dimensional interconnected porous graphene (3D-IPG) foam structure. The 3D-IPG foam structure is constructed of three-dimensional interconnected graphene sheets formed as a plurality of monolayers, and having an flexible interconnection architecture. The flexible interconnection architectures allow the 3D-IPG to maintain a high interfacial thermal conductance by the 3D-IPG filling a gap between a heat source and a heat sink across the interface, and by capping small features up to nanoscale roughened surfaces.

Abstract: The described method and system provide an efficient routing of data packets protocol in an event-driven and delay-constrained WSN (wireless sensor network) that optimizes the sleep/wake schedule of nodes to maximize the lifetime of the WSM, subject to a constraint on the source-to-sink delay. Online forwarding techniques may be used to transfer data reports from monitoring nodes to the sink. A delay-constrained and energy-efficient routing protocol (DCEER) for asynchronous WSNs may be used to maximize the lifetime of the WSN while remaining within the maximum allowable delay requirements. With DCEER, each node may maintain the historical cost of forwarding a packet from itself to the sink as its virtual coordinate, and packets are forwarded in the direction of descending coordinates. The cost-based coordinates may change dynamically with a time-varying channel or topology.

Abstract: An apparatus using reconfigurable integrated sensor elements with an efficient energy harvesting capability is described. Each sensor element has sensing and energy harvesting mode. In the sensing mode, the sensor element measures an environmental characteristic by generating electrical charge and outputs a time-encoded signal indicative of the measurement. In the energy harvesting mode, the sensor element itself is used to harvest energy from ambient energy source and makes it available to other sensor elements or circuit components. The sensing element is switched from the sensing mode to the energy harvesting mode when the electrical charge reaches a predetermined threshold. An image sensor device using asynchronous readout for harvesting energy from incident light while generating images is also described.

Abstract: Described herein is a circuit and related method for improving the dynamic range and the linearity characteristic of a CMOS image sensor. In various embodiments of the CMOS image sensor, a current sampler, a comparator, and a 1-bit memory are incorporated in each pixel circuit. In the image sensor, pixels are arranged in columns and a column slice is used to read the digital and analog singles from each column. In addition, a calibration circuit is incorporated in the sensor circuit for providing calibration current, which is used to generate calibration parameter. The image sensor operates in three non-overlapping modes: the difference mode, the WDR mode, and the calibration mode. The image sensor is switched among the three modes by control signals, which are provided to the image sensor by various control circuits. The image sensor normally operates in the difference mode and switches to the WDR mode when the difference between consecutive frames is over a threshold.

Aligned carbon nanotube films of thickness ranging from 1 ?m to over 100 ?m were obtained. By manipulating various operating factors—position of substrate in the reactor, amount of water vapor, amount of catalyst, reactor temperature, and growth time, the morphology and thickness of these carbon nanotube films could be adjusted.

Abstract: A system and method of integrating IP multicasting with application layer multicasting for media streaming. The proposed approach teaches forming an overlay P2P tree using a scalable protocol. New node either detects an existing IP multicasting island to join or forms a new one. Ingress node of each island is adaptively elected and streams media to nodes in its island via IP multicasting, while getting the media from its parent node via traditional unicast to achieve much lower end-to-end delay and link stress.

In addition, the interposer assembly is attached and connected to a substrate layer, which is in turn attached and connected to a printed circuit board. In order to provide improve thermal management, the interposer surface carrying the high-power chips are oriented away from the circuit board. A heat spreader is attached to the back sides of the high-power chips for dissipating the heat.

The passivation facilitates simultaneous realization of effective/high current collapse suppression and low leakage current without the use of a sophisticated multiple-field plate technique. The passivation can be achieved by growing a charge-polarized AlN thin film on the surface of a group III-nitride based heterojunction device by plasma-enhanced atomic layer deposition such that positive polarization charges are induced at the interface to compensate for a majority of negative charges at the interface.
