Abstract: A system for processing text files to extract and create conceptual graphs. The system determines key terms, prescribes a set of edge relations (i.e., defines edge categories), and the extracts conceptual graphs from source documents, including raw text, using these representations together with a semantic parser, followed by post processing. The conceptual graphs can then be used for a variety of purposes, including the creation of questions in an automated tutor system.

Abstract: A personal air filtration device and methods of using the same for providing a zone of filtered air proximate a breathing zone of a user are described. A blower provides an air flow to a head support which delivers the air flow to a zone proximate the users head. The air flow passes through a filter. The filter can be a point of delivery filter disposed about an air permeable surface of the head support. The delivered air flow can provide a laminar air flow defining a zone of filtered air about the user's breathing zone.

Abstract: A neck-worn personal air filtration device for providing a zone of filtered air around or near a user's breathing zone is described. The device comprises a blower, a hose, and a neck-worn plenum including a filter. Air blown from the blower, passes through the hose and into the plenum exiting the plenum. The air is filtered by a filter for breathing by the user.

Abstract: A method, apparatus, and system for managing load in a server are provided. The server performs events for a plurality of electronic communication devices, each of the devices enabled to transmit to the server, at a respective given time and at a respective given frequency, a request to perform a respective event. The server receives the requests and determines that its load is above a threshold load value during a given time period when the requests arrive. In response, for a subset of the devices, the server transmits a delay time to each electronic communication device in the subset. The delay time causes each device in the subset to change the respective given time to a respective new time comprising the delay time added to the respective given time such that a next request is transmitted from each device in the subset to the server at the respective new time.

Abstract: The present invention relates to a computer implemented method and system for determining the source of a determined performance variance of a complex entity, and determining one or more different actions to be taken as a consequence of the determined source of performance variance.

Abstract: A third party that performs data stream computation is requested to return not only the solution to the computation, but also “annotations” to the original data stream. The annotations are then used by the data owner (in actuality, a “verifier” associated with the data owner) to check the results of the third party's computations. As implemented, the verifier combines the annotations with the original data, performs some computations, and is then assured of the correctness of the provided solution. The cost of verification is significantly lower to the data owner than the cost of fully processing the data “in house”.

Abstract: Methods for determining the appropriateness of anti-platelet therapy in a patient with a platelet-affected disease. The Mean Platelet Component value in a patient blood sample is determined corresponding to the patient's platelet activation status. A high platelet activation status indicates the appropriateness of anti-platelet therapy.

Abstract: Methods are disclosed for monitoring patients utilizing Mean Platelet Component values during therapeutic intervention.

Abstract: Methods for assessing patient risk for platelet-affected disease states are disclosed. Also disclosed are methods for predicting the appropriateness of platelet antagonist therapy, and for monitoring patients during therapeutic intervention or during a combined regimen of therapy and angioplasty.

Abstract: A warming device includes a clinical garment having an inside surface supporting a convective apparatus with separately-inflatable sections, each adapted to enable a particular mode of warming. Each section has a surface or region with a permeability that varies from the permeability of a surface or region in another section.

Abstract: Implementing asymmetrical wireless communications without significant wastage of bandwidth within the up-link block of frequency spectrum is becoming increasingly important. If the frequency spectrum is divided such that a single up-link block is paired with a plurality of corresponding down-link blocks of similar bandwidth size and respective fixed frequency offsets, the bandwidth efficiency of spectrum usage can improve when considering many data applications such as the Internet. MTs that utilize different down-link blocks can share a common up-link block so that, in ideal statistical situations, the up-link block statistically runs out of bandwidth at approximately the same time as the combination of the down-link blocks. With fixed frequency offsets between the up-link block and each of the plurality of down-link blocks, the design of the STS and the MTs can be kept reasonably simple.

Abstract: A compression technique is used to suppress the idle or silent portion of both stations in a facsimile transmission. Facsimile transmission is a half-duplex protocol resulting in considerable idle time for either the called terminal or the calling terminal. The invention provides a signal level threshold for each station whereby signals above the threshold are allowed to pass through while signal levels below threshold are not, resulting in more efficient network bandwidth utilization.

Abstract: A plurality of terminals, such as digital telephones, are connected to a serial data bus formed by a balanced two-wire line. Each terminal transmits bytes bit-serially with the magnitude bits first, in order of decreasing significance, then the sign bit, and finally an even parity bit to maintain the balance of the line, the "1" bits being transmitted with alternating polarity. The terminals operate simultaneously and in synchronism. If a terminal, during a "0" bit of a byte which it is transmitting, detects a "1" pulse on the bus from another terminal, then it gives up transmission for the remainder of that byte and receives the greater magnitude byte which prevails on the bus. Thus a single two-wire line can be used for digital transmission in both directions between arbitrary numbers of telephones.
