Granted: 2006-02-21
Abstract: An advance notification system (10) and method notifies system users of the impending arrival of a transportation vehicle (19), for example, a school bus, at a particular vehicle stop. The system (10) generally includes an on-board vehicle control unit (VCU) (12) for each vehicle (19) and a base station control unit (BSCU) (14) for making telephone calls to users in order to inform the users when the vehicle (19) is a certain predefined time period and/or distance away from the vehicle stop. The VCU (12) compares elapsed time and/or travelled distance to the programmed scheduled time and/or travelled distance to determine if the vehicle (19) is on schedule. If the vehicle (19) is behind or ahead of schedule, the VCU (12) calls the BSCU (14), which then adjusts its calling schedule accordingly. Significantly, a calling report generator (11) in the BSCU (14) allows a system user to solicit a calling report from the BSCU (14) that indicates the time(s) and outcome(s) of any previous notification attempt(s) by the BSCU  (14) to the user telephone (29).

Abstract: The damper includes a damper housing and a piston assembly reciprocating therein. The damper housing includes an attachment device formed of an interior partially circular wall with a triangular cross section thereby forming an interior partially circular apex for engaging a cylindrical boss. This allows the damper to rotate about an axis of the interior partially circular wall and pivot about an axis perpendicular to the rotational axis.      Additionally, the piston assembly includes a detent protrusion formed from a stem supporting a head, the radius of the head being greater than that of the stem. The detent protrusion is engaged by a keyhole-shaped aperture with a first portion with a radius of curvature substantially equal to that of the stem and a second portion with a radius of curvature substantially equal to that of the head. The detent protrusion can therefore rotate within the keyhole-shaped aperture. Additionally, the cap of the damper housing is formed of elastic O-rings to allow the piston assembly to rotate within the damper housing.

Abstract: The present invention relates to a method for identification of cellular protein antigens to which patients with cancer, or patients at risk for cancer, may develop autoantibodies. The method of the invention involves the use of patient derived sera for the identification of the cellular protein antigens using two-dimensional gel electrophoresis followed by Western Blot analysis. The identification of such protein antigens provides novel markers that can be utilized for screening, for diagnostics and prognosis of disease. The invention also provides for the use of the identified protein antigens in immunoassays designed to detect the presence of serum antibodies to the specific protein antigens in sera from individuals that may harbor such antibodies. The invention further relates to the use of the identified antigens as immunogens for stimulation of an immune response in patients expressing such protein antigens. The invention is demonstrated by way of example in which elevated levels of circulating autoantibodies reactive against a tumor specific antigen were identified in sera derived from a lung cancer patient. In addition, elevated levels of circulating autoantibodies reactive against several specific .beta.-tubulin isoforms were detected in the sera of neuroblastoma patients.

Title: Adaptive media control
Inventor: GANZ AURA
IPC: H04J3/22
Filed: 1998-08-13
Granted: 2011-04-26
Abstract: A media control approach that supports transmission of data streams with QoS requirements, such as minimum throughput or maximum delay, while adapting to the changing characteristics of the transmission medium. The media control approach includes use of a polling manager (324) and a resource manager (322). The resource manager (322) provides an admission control procedure that prevents admission of sessions that cannot be supported by the system and allocates network resources needed to support admitted sessions. The polling manager (324) uses an efficient "just in time" polling of stations based on their allocated bandwidth or communication rates. Stations that do not use their allocated rates are polled less often than those which use their allocation, thereby increasing the total throughput of the system and providing proper quality of service support for real-time application.

Abstract: The invention relates to a threshold extension block phase estimator (TEBPE) which gives improved performance over existing BPE algorithms in the presence of noise. Specifically, the threshold and sector slip performance is superior to that of previously disclosed algorithms. This can be of crucial advantage in coded systems. Another attribute of the TEBPE is that it can be configured as a hybrid feedback loop incorporating characteristics of both the BPE and the PLL. This gives a high degree of flexibility with very fast acquisition times at high signal-to-noise ratio (SNR), and improved threshold performance at low SNR.

Abstract: La présente invention concerne un système d'émission en anneau à multiplexage par répartition à longueur d'ondes (MRL), équipé de deux concentrateurs. Des groupes identiques de signaux optiques destinés à être émis sur l'anneau sont entrés dans les deux concentrateurs, mais l'un des concentrateurs comprend des commutateurs optiques destinés à faire passer sélectivement l'un des groupes de signaux optiques vers l'anneau MRL. En conséquence, si une faute se produit dans l'une des connexions concentrateur-réseau, ou si l'un des concentrateurs tombe en panne, les commutateurs couplent les signaux optiques du concentrateur en activité à l'anneau MRL. En outre, les signaux optiques émis par les noeuds couplés à l'anneau MRL sont sortis des deux concentrateurs, ce qui permet d'assurer la sortie et l'entrée de signaux dans l'anneau, même si l'un des concentrateurs tombe en panne.

Abstract: A method is disclosed for predicting the presence of an abnormal level of one or more proteins in the clotting cascade from at least one time-dependent measurement profile. At least one time-dependent measurement on an unknown sample (103) is performed and a respective property of the sample is measured over time so as to derive a time-dependent measurement profile (101).  A set of a plurality of predictor variables (110) are defined which sufficiently define the data of the time-dependent measurement profile (101). A model (113) is then derived that represents the relationship between the abnormality and the set of predictor variables (110). Subsequently, the model (113) is utilized to predict which protein or proteins in the clotting cascade are at an abnormal level, with the prediction (120) being a better prediction than clot time alone.

Abstract: A method and apparatus for compressing packets that enables inter-packet compression thereby achieving greater robustness and increased compression ratios. More particularly, a variable-length coding is used in conjunction with maintaining a separate hash table for each packet. Further, the per-packet hash table indexes particular byte strings in the packet but does not index data in any other packet(s).  That is, a respective separate hash table for each packet is employed wherein such hash table is constructed as the particular packet is compressed. As such, the respective hash table is encoded with the particular packet. Employing a per-packet hash table in combination with variable history state inter-packet compression provides for efficient and robust overall compression of the packets.
