摘要： The invention provides a highly sensitive immunoassay for detection of a biological species. The immunoassay comprises exposing an electrode to an analyte liquid putatively containing the biological species so as to couple the biological species, if present in the analyte liquid, to a binding antibody on the electrode. The electrode comprises a binding antibody and an anchor group, each being coupled to an electrically conductive substrate, said binding antibody being capable of binding to the biological species and said anchor group being capable of binding to a redox polymer. The electrode is then exposed to an antibody-enzyme liquid comprising an antibody-enzyme species, said antibody-enzyme species comprising a detection antibody capable of binding to the biological species, said detection antibody being coupled to a redox enzyme, whereby, if the analyte liquid comprises the biological species, the redox enzyme couples to the electrode by means of the coupling of both the detection antibody and the binding antibody to the biological species. The electrode is then exposed to a polymer solution comprising the redox polymer and to an enzyme substrate, whereby if the redox enzyme is coupled to the anchor group on the electrode the redox polymer is reduced and couples to the anchor group on the electrode. A voltage is then applied between the electrode and a reference electrode and the electrode is exposed to an oxidisable species, whereby a magnitude of an electric current between said electrode and a reference electrode is indicative of the presence or absence of the biological species.

摘要： Controller scaling and parameterization are described. Techniques that can be improved by employing the scaling and parameterization include, but are not limited to, controller design, tuning and optimization. The scaling and parameterization methods described here apply to transfer function based controllers, including PID controllers. The parameterization methods also apply to state feedback and state observer based controllers, as well as linear active disturbance rejection (ADRC) controllers. Parameterization simplifies the use of ADRC. A discrete extended state observer (DESO) and a generalized extended state observer (GESO) are described. They improve the performance of the ESO and therefore ADRC. A tracking control algorithm is also described that improves the performance of the ADRC controller. A general algorithm is described for applying ADRC to multi-input multi-output systems. Several specific applications of the control systems and processes are disclosed.

摘要： Embodiments are directed toward a method for Behavior-based Traffic Differentiation (BTD) that initially receives incoming packets and performs traffic classification to determine the protocol of the incoming packets. In addition, BTD performs bandwidth division/allocation to further support traffic classification amongst non-TCP traffic such as UDP and ICMP. For TCP traffic, the method for BTD determines whether a TCP connection has been established and performs at least one of rate limiting, waiting time reduction for half-open connections, and incrementing backlog queue size when the TCP connection has not been established. If the TCP connection has been established successfully, the method for BTD further includes proactive tests for traffic differentiation which identify normal traffic, which is admitted, and attack traffic, which is dropped.

摘要： Multiple designs, systems, methods and processes for controlling a system or plant using an extended active disturbance rejection control (ADRC) based controller are presented. The extended ADRC controller accepts sensor information from the plant. The sensor information is used in conjunction with an extended state observer in combination with a predictor that estimates and predicts the current state of the plant and a co-joined estimate of the system disturbances and system dynamics. The extended state observer estimates and predictions are used in conjunction with a control law that generates an input to the system based in part on the extended state observer estimates and predictions as well as a desired trajectory for the plant to follow.
