Abstract: Communication in a broadcast-only distributed wireless network of nodes is provided. Each of the nodes of the network uses a repeated communication frame with an idle period and a TDMA schedule for active communication. The active TDMA schedule of at least some of the nodes in the network are aligned and synchronized. The distributed network does not require a central node for coordinating the TDMA schedules of another node or for synchronizing the communication frames. TDMA slots of the TDMA schedule are used for broadcasting and receiving messages. A node broadcasts a message without the use of an address of the receiving node. Communication frames having dynamic properties, such as communication frame length and start time, TDMA schedule position and length, and idle period position and length, are provided. Distributed functions for nodes to search for and synchronize with other nodes are also provided.

Abstract: The present invention provides a system for window blast protection. The system includes a first material, which is either elastomeric or non-elastomeric, which is bonded to a second material, which is elastomeric when the first material is non-elastomeric, and is non-elastomeric when the first material is elastomeric. The system also includes a cover for protecting the materials, where the cover releases the materials in response to the pressure impact of an explosive blast. The second material is anchored to the inside of the cover. When the system is in use, the system further includes a bonding agent for bonding the first material to a film attached to the inner surface of the window and an anchoring means for anchoring the outside of the cover to a frame or wall surrounding the window.

Abstract: Observation-based user profiling and profile matching are provided. The network behavior of users of a computer-implemented social network are observed and used for user profiling. By observing network behavior instead of necessarily relying on user self-reported data, accurate and objective user profiles can be formed; user profiling is accomplished based on the observed network behaviors with or without the knowledge of the user being profiled. The observed network behaviors can include the customization of a visual graphic, a media preference, a communication preference, or a selection of words from a word list. The user profiles can be with respect to a domain and two or more users can be matched based on their profiles with respect to the same domain. User ratings and profile updating based on the ratings are also provided.

Abstract: Partitioning electronic sensor packages is provided. The electronic sensor package includes an electronic component, a sensor device, and electrical connections between the electronic component and the sensor device. A dam is written in the electronic sensor package to partition the package into two or more sections, where the sensor device is situated at least partially in one section and the electronic component is situated at least partially in another section. The partitioning of the dam allows the two sections to be filled with different fill materials. For example, the section with the sensor device can be filled with a soft gel-like material to provide some moisture protection to the sensor device without causing detrimental stresses to the sensor device, while the section with the electronic component can be filled with a highly moisture protective epoxy.

Abstract: Automatic placement of safety cones from a moving vehicle is provided. The preferred safety cone would have a flexible cone part. A receptacle holds a plurality of safety cones either with the flexible cone part in non-compressed position or in spring-loaded position. The receptacle is removably attached to the vehicle. A releasing means that is attached to the receptacle is controlled and advances the safety cones in an automatic and controlled fashion, one-by-one, to different locations on a ground surface from a moving vehicle. The advantage is that it automatically handles the placement of a plurality of safety cones while driving. There would be no more need for a person to manually place the safety cones. It provides for increased road safety since it decreases or even eliminates the number of fatal or non-fatal accidents as well as chronic injuries of road-workers that are involved in placing safety cones.

Abstract: A general imaging scheme is proposed for applications of CBCT. The approach provides a superior CBCT image quality by effective scatter correction and noise reduction. Specifically, in its implementation of CBCT imaging for radiation therapy, the proposed approach achieves an accurate patient setup using a partially blocked CBCT with a significantly reduced radiation dose. The image quality improvement due to the proposed scatter correction and noise reduction also makes CBCT-based dose calculation a viable solution to adaptive treatment planning.

Abstract: A system for auto-anastomosing a region of the body using magnetic members that may be individually delivered to different locations in the body. The magnetic members have a polar alignment that generates an attractive force to compress tissue in the region between them. The tissue in the region necroses as a result of the compressive force such that tissue surrounding the necrosed tissue heals together to form an anastomosis. A cutting member may be coupled to either the first or second magnetic member to create a temporary opening in the tissue.

Abstract: Motion capture animation, shape completion and markerless motion capture methods are provided. A pose deformation space model encoding variability in pose is learnt from a three-dimensional (3D) dataset. Body shape deformation space model encoding variability in pose and shape is learnt from another 3D dataset. The learnt pose model is combined with the learnt body shape model. For motion capture animation, given parameter set, the combined model generates a 3D shape surface of a body in a pose and shape. For shape completion, given partial surface of a body defined as 3D points, the combined model generates a 3D surface model in the combined spaces that fits the 3D points. For markerless motion capture, given 3D information of a body, the combined model traces the movement of the body using the combined spaces that fits the 3D information or reconstructing the body's shape or deformations that fits the 3D information.

Abstract: Detecting and identifying ions using surface enhanced Raman spectroscopy (SERS) and an ion separation pre-filter, such as an ion spectrometer, are provided. The combination of an ion separator as a pre-filter for SERS provides a highly sensitive detector with very low false alarm rates. Target ions from an ionized sample are identified and separated by the ion separator. The target ions are steered and deposited onto a SERS substrate for Raman spectroscopic analysis with an optical probe. The Raman spectrum is compared with reference spectra and the composition of the sample is identified. The ion current from the target ions can also be measured, preferably concurrently with the Raman spectrum measurement. Types of ion separators include a differential ion mobility spectrometer, an ion mobility spectrometer, or a mass spectrometer.

Abstract: A method and system for encrypting a first piece of information M to be sent by a sender [100] to a receiver [110] allows both sender and receiver to compute a secret message key using identity-based information and a bilinear map. In a one embodiment, the sender [100] computes an identity-based encryption key from an identifier ID associated with the receiver [110]. The identifier ID may include various types of information such as the receiver's e-mail address, a receiver credential, a message identifier, or a date. The sender uses a bilinear map and the encryption key to compute a secret message key gIDr, which is then used to encrypt a message M, producing ciphertext V to be sent from the sender [100] to the receiver [110] together with an element rP. An identity-based decryption key dID is computed by a private key generator [120] based on the ID associated with the receiver and a secret master key s.

Abstract: A method and apparatus for convolving spectroscopic data with certain phase information for practicing phase-compensated sensitivity-enhanced spectroscopy (PCSES). PCSES uses a beam of radiation in a polarization state PSp from a source emitting at a plurality of wavelengths, and places in the beam a compensator capable of altering polarization state PSp by applying a delimited phase shift ? between two orthogonal polarization axes of the radiation to restrict a finely-vibrating spectrum. A sample disposed in the beam after the compensator generates a response beam by reflection, transmission or even both. A polarization state PSa of the response beam is passed to a detector to determine a spectrum of the response beam. A first spectrum is collected when polarization states PSp, PSa and the compensator are in a first polarization-altering configuration and a second spectrum is collected when polarization states PSp, PSa and the compensator are in a second polarization-altering configuration.

Abstract: A medical imaging-based system and method uses both kV and MV images captured during a treatment period for organ motion tracking. 3D geometric locations of internal features are computationally tracked as a function of time from internal features, such as natural biological features or implanted fiducials, which are computationally extracted from the captured kV and MV images. A partial information method allows 3D tracking to be maintained in the event that imaging information is temporarily not available.

Abstract: A computer-implemented method for updating a web user interface on a client device is provided. A router back-boned to the Internet communicates with the client device web-user interface data defined in markup language to dynamically update the web-user interface on the client device. The router contains no logic regarding the web-user interface running on the client device. The client device has a browser server for dynamically updating the web-user interface through downloading and caching the data from the router. The browser server on the client device has (i) a user interface model of the web-user interface running on the client device defined in Javascript, and (ii) a JavaScript Runtime Engine for dynamically converting the downloaded and/or cached web-user interface markup language data into JavaScript objects. The web-user interface is dynamically updated by combining steps (i) and (ii).

Abstract: An advanced water treatment method processes a continuous flow of water in a sequence of stages including pre-filtering to remove solids, conditioning to adjust pH, blending with a recycled dense microalgae culture, and passing the resulting mixture through an enclosed, environmentally-controlled photobioreactor where nutrients, PCB's, trace metals and other pollutants and regulated compounds are taken up by the algae. The flow from the PBR is separated using cross-flow filtration to produce a treated water flow and a dense microalgae flow that is recycled to the blending stage upstream. Thus, whereas the algae is recycled, the water entering the system is treated by flowing sequentially through the stages of the system, without any recycling or repetition of treatment stages.

User-created notes are enriched with labels, context traits, and relevant data to minimize friction in the note-taking process. In other words, the present invention is directed to collecting unscripted data, adding more meaning and use out of the data, and binding the data to services. Mutable and late-binding to services is also provided to allow private thoughts to be published to a myriad of different applications and services in a manner compatible with how thoughts are processed in the brain. User interfaces and semantic skins are also provided to derive meaning out of notes without requiring a great deal of user input. Linking physical objects to notes are also provided, such as through QR codes.

Abstract: A method of growing spatially-separated and size-controlled particles on substrate surfaces is provided. The method utilizes chemical modification of the substrate surface, an atomic layer deposition (ALD) system, providing a modified layer to the substrate surface and providing an ALD material for nanoparticle deposition. The method induces a Volmer-Weber growth method, where islands of the nanoparticles are formed on the surface. The modified layer controls a number of nucleation sites on the surface, where controlling the number of ALD cycles limits an amount of deposited the material for discrete the nanoparticles.

Abstract: A method of locating the source of an unknown signal is provided that includes calculating a differential offset for a signal for each of a plurality of positions within a region in which the transmitter must lie, for each of a series of times m with respect to first and second signal relays and respective first and second receivers, the positions of the signal relays and receivers being known, generating a cross-ambiguity function (CAF) using data corresponding to samples of the unknown signal received at the first and second receivers via the first and second signal relays respectively, estimating the level of noise in the CAF, and using this data to obtain a measure of the likelihood that the source is located within defined areas within the region, where the differential offsets are differential time offsets, or differential frequency offsets, or both. The method provides location which is unconditionally convergent.

Abstract: A method of using electrokinetics for separating particles in a buffer solution is provided, where a chromatographic column is provided having a non-uniform internal longitudinal cross-section. At least one main inlet for inputting solution and at least one main outlet for outputting solution are provided. At least one sample inlet and at least one sample outlet are provided. The particle is introduced to the column from the sample inlet and fractionated samples are eluted from the sample outlet, where quality control and further analysis are enabled. An electric field is applied to the solution in the column to generate a charged double layer at a solid-liquid interface within the column. The electric filed moves ions within the double layer, and a non-uniform velocity profile is induced to the buffer solution. The moving ions carry the particles along the column and the particles are separated according to size or charge.

Abstract: A biologically inspired climbing device with toes and spines is provided. The device has toes capable of moving independently from each other. Each toe distinguishes a compliant linkage, which has non-compliant parts and compliant parts. Spines are distributed over each of the toes. The spines have a diameter that is less than or equal to a diameter of an asperity of a surface. The toes with spines could be arranged into one or more feet. The feet could then be organized in legs enabling the device to climb a surface in a gait pattern. The device uses low power and is quiet, leaves no traces or tracks behind, works well on smooth, rough, uneven, porous and dirty surfaces, and is able to carry and support its own body weight.

Abstract: A computer-implemented method to correct motion and interpolation effects for functional magnetic resonance imaging (fMRI) analysis is provided. The method estimates the motion on every voxel of the data and removes those effects to leave a residual signal that can be analyzed to high accuracy. The estimation of the motion includes solving a normal matrix equation based on the local translational motion of each voxel of the head, and a regularization parameter that depends on the local spatial structure of the head. Methods to regularize a matrix from the normal equation using the regularization parameter are also provided. A rolling filter implementation for real-time processing and motion correction is provided.
