  • Patent number: 11234628
    Abstract: The present invention provides systems and methods for detection and diagnosis of concussion and/or acute neurologic injury comprising a portable headwear-based electrode array and computerized control system to automatically and accurately detect cortical spreading depression and acute neurological injury-based peri-infarct depolarization (CSD/PID). The portable headwear-based electrode system is applied to a patient or athlete, and is capable of performing an assessment automatically and with minimal user input. The user display indicates the presence of CSD/PID, gauges its severity and location, and stores the information for future use by medical professionals. The systems and methods of the invention use an instrumented DC-coupled electrode/amplifier array which performs real-time data analysis using unique algorithms to produce a voltage intensity-map revealing the temporally propagating wave depressed voltage across the scalp that originates from a CSD/PID on the brain surface.

  • Publication number: 20160031713
    Abstract: A method of producing high grade activated carbon is introduced. The method entails providing soft wood biomass material pretreated to result in a mass of fermentation residual solids having a desired content of lignin. The material is pyrolyzed/carbonized in an inert environment at a temperature rate of 10° C./min up to an upper temperature range and held at the upper temperature range for up to one hour to produce char. Thereafter, the char is activated by changing the inert environment after about one hour at the upper temperature range to an oxidizing environment at a desired oxidizing gas flow rate for a predetermined time period. The environment is then switched back to an inert environment and allowed to cool until room temperature is reached so as to produce the activated high grade carbon. Applications for the material include but is not limited to: carbon electrodes in supercapacitors and mercury adsorbent material.

  • Patent number: 8973011
    Abstract: Techniques for multi-core resource utilization planning are provided. An agent is deployed on each core of a multi-core machine. The agents cooperate to perform one or more tests. The tests result in measurements for performance and thermal characteristics of each core and each communication fabric between the cores. The measurements are organized in a resource utilization map and the map is used to make decisions regarding core assignments for resources.

  • Patent number: 8801306
    Abstract: Systems and techniques relating to printing include an apparatus including a base mounting a storage spool to store printing ribbon including a web carrying marking medium, the base mounting a ribbon take-up spool. A ribbon path from the storage to the take-up spool runs through a printing station where there is a print head, and printing is effected at the printing station when relatively moving the head and the substrate with the ribbon interposed between. The apparatus includes a movable ribbon guide member, a ribbon guide member drive device to move the ribbon guide member, and a controller which, during or in between at least some printing operations, controls drive of at least the take-up spool to advance ribbon through the printing station. The controller controls the ribbon guide member in response to an input signal representative of ribbon tension along the ribbon path to adjust the ribbon tension.

  • Patent number: 8327738
    Abstract: A composite transmission housing includes resin transfer molding or vacuum assisted resin transfer molding manufacturing processes combined with discontinuous fiber preforms. The preforms are assembled in a prepared injection and cure mold with additional details and fillers. The preforms are constructed such that the preforms are assembled into the mold in a specific order to assure proper arrangement. Using a combination of vacuum and pressure, a resin is injected into the mold to completely infuse the assembled preforms. At completion, the mold is heated to the resin cure temperature and held at this temperature for sufficient time to insure complete cure.

  • Publication number: 20100160781
    Abstract: A noninvasive technique that can be used to deny blood flow to a particular region of tissue, without the inherent risks associated with invasive procedures such as surgery and minimally-invasive procedures such as embolization. Blood flow in selected portions of the vasculature can be occluded by selectively treating specific portions of the vasculature with high intensity focused ultrasound (HIFU), where the HIFU is targeted Doppler ultrasound data, and a duration of the therapy is automatically controlled using a negative feedback loop provided by Doppler ultrasound data collected during the HIFU therapy. A portion of the vasculature providing blood flow to the undesired tissue is selected by a clinician, or automatically selected based on Doppler data, and HIFU is administered to the selected portion of the vasculature to occlude blood flow through that portion of the vasculature.

  • Patent number: 7603104
    Abstract: A system of operating a wireless handset capable of making clear and secure calls is claimed. A secure call may be made by pressing a key for a predetermined amount of time. The handset enters a secure mode if the key is held for a time period greater than the predetermined amount of time. The handset enters a clear mode if the key is held for a time period less than the predetermined amount of time.

  • Patent number: 7526706
    Abstract: A computer implemented method, apparatus, and computer usable program code to determine whether an acknowledgment packet from an end point acknowledges receipt of unsent data in response to receiving the acknowledgement packet over a connection with the end point. A determination is made as to whether acknowledgement packets for unsent data have been received sequentially a selected number of times over the connection in response to the acknowledgement packet being for unsent data. The acknowledgment packet is dropped if acknowledgement packets have been received sequentially the selected number of times over the connection.

  • Publication number: 20080091696
    Abstract: A schema identifies a field in a document as a key field. Using an XML schema, the key field can be identified by attaching a property to the element or attribute to be used as a key field (if the XML schema standard is modified to support properties). Otherwise, attributes can be used to identify the element or attribute that is to be a key field. Fields can be primary keys, secondary keys, or foreign keys, as supported by data stores. The data store can analyze the schema to determine which fields are key fields. The key fields can be duplicated in the native format of the data store for use in indexing, searching, and other data store functions on the documents. The documents themselves can be stored as objects, into which the data store cannot reach, or can be stored in the native format of the data store, as desired.

  • Publication number: 20080052283
    Abstract: A directed set can be used to establish contexts for linguistic concepts: for example, to aid in answering a question, to refine a query, or even to determine what questions can be answered given certain knowledge. A directed set includes a plurality of elements and chains relating the concepts. One concept is identified as a maximal element. The chains connect the maximal element to each concept in the directed set, and more than one chain can connect the maximal element to any individual concept either directly or through one or more intermediate concepts. A subset of the chains is selected to form a basis for the directed set. Each concept in the directed set is measured to determine how concretely each chain in the basis represents it. These measurements for a single concept form a vector in Euclidean k-space. Distances between these vectors can be used to determine how closely related pairs of concepts are in the directed set.
