Abstract: Electronic devices (10, 30, 50) utilizing electrically-controlled liquid components to accomplish device switching. Electric fields are used in a device structure to manipulate the position and/or geometrical shape of a conductive fluid or liquid (60, 24) using electrowetting. This manipulation regulates the flow of current between electrodes of the device structure, such as the source and drain regions (16, 20) of a transistor construction, by bridging a non-conductive channel (15) separating the electrodes (16, 20) so that the electrodes (16, 20) are electrically coupled.

Abstract: The present invention is directed towards a prosthetic anchor (36) including a central layer (1) through which embedded fibers (2), such as artificial tendons, pass in defined pathways (4), a ‘deep’ surface membrane (7) which interfaces with a hard structure, whether that is a prosthesis, a bone, or other hard tissue, and a ‘superficial’ surface membrane (8) which interfaces adjacent tissue and may be configured to adhere or not to adhere to that tissue. The central layer (1) is positioned intermediate the surface membranes (7, 8) which are mechanically and/or adherently attached thereto. Also, non-limiting examples of methods of fabrication and of affixing the anchor (36) to a relatively rigid structure, natural or prosthetic, in a human or animal body with improved stress distribution in the fixed tension member end are taught.
Abstract: As various applications of wireless ad hoc network have been proposed, security has become one of the big research challenges and is receiving increasing attention. The present invention provides for a distributed key management and authentication approach by deploying the recently developed concepts of identity-based cryptography and threshold secret sharing. Without any assumption of pre-fixed trust relationship between nodes, the ad hoc network works in a self-organizing way to provide the key generation and key management service, which effectively solves the problem of single point of failure in the traditional public key infrastructure (PKI)-supported system. The identity-based cryptography mechanism provided not only to provide end-to-end authenticity and confidentiality, but also saves network bandwidth and computational power of wireless nodes.

Abstract: A rotary drill bit having one or more fluid nozzles is provided. Each nozzle may include interior surfaces designed to optimize hydraulic performance and efficiency of fluid flowing through the nozzle. The interior surfaces cooperate with each other to minimize turbulent fluid flow through the respective nozzle. Each nozzle may also include a discharge port or outlet with at least one Coanda surface operable to direct fluid flow in a direction which optimizes efficiency of transferring fluid energy to adjacent portions of a wellbore. The orientation of fluid flow from each nozzle may be directed to optimize cleaning of associated cutting structures and/or to minimize or prevent balling of formation cuttings.

Abstract: The present invention describes reagents and methods for using concatermized double-stranded oligonucleotide molecules (CODN) for transcription factor decoys. In one embodiment, the concatemers consist of a variable number of end-to-end copies of a short dsDNA containing a sequence or sequences that act as transcription factor decoys.
Abstract: A process for the encapsulation of liquid particles within nanometer thick polymer shells utilizes an interfacial free radical alternating copolymerization process. Encapsulating a liquid material includes providing a mixture comprising the liquid material to be encapsulated, a hydrophobic monomer in a non-polar solution and a hydrophilic monomer in a polar solution. The liquid material is compatible in either the polar solution or the non-polar solution. The polar solution and the non-polar solution are not miscible in each other. The mixture is homogenized to form an emulsion, and then polymerized by an initiator which initiates an interfacial free radical alternating copolymerization process. The copolymerization process is optimally constrained to proceed only at the hydrophobic and hydrophilic interface thus forming a polymer around the liquid material.

Abstract: The present invention provides for a slow-release inhibitor that is applied to a metal surface, such as by way of a paint or primer coating, for corrosion control of the metal. An exemplary embodiment of the slow-release corrosion inhibitor includes a water-soluble particle, or pigment, and an organic polymeric film that encapsulates the particle. This water-soluble particle may be either organic or inorganic and, preferably, is non-carcinogenic and non-toxic. An additional water-soluble particle having an encapsulating, organic polymeric film further may be provided along with a water-soluble, organic compound to form the corrosion inhibitor. The polymeric film(s) are of a desired hydrophobicity and permeability to permit, upon interaction of the particle(s) with water, controlled diffusion of particle ions therethrough.
