    摘要： An integrated policy enforcement system for a computer network implements several policies on the network traffic. A rule compiler compiles these policies and converts them into a rule tree-graph, which is then used to provide desired behavior to the network traffic comprising data packets. The rule compiler comprises three sub-modules namely—a rule input module, a rule tree generator module and a rule output module. The rule input module receives the input for the rule compiler and prepares the input for the rule tree generator module. The rule tree generator module generates the rule tree-graph. The rule tree-graph is a data structure comprising tree data structure and graph data structure. Such a data structure combines the properties of tree data structure and graph data structure, and enhances the performance of the policy enforcement systems by striking a balance between the memory requirement for storing the data structure and the processing capabilities of the system required to process the network traffic. The Output module converts the rule tree-graph to policy files, which can be downloaded to various modules of the policy enforcement systems.

    摘要： A high-speed sampling system and an analog to digital converter are disclosed. One embodiment of a method of sampling a signal includes receiving an analog signal and generating first samples at a rate of Fs, and generating second sub-samples from the first samples at a rate of Fs/N and having a relative phase of approximately (360/N)*(i-1) degrees, where i varies from 1 to N. In a first embodiment, at most two second sub-samplers are tracking the output of the first sampler at any point in time. In a second embodiment, only one of the N second sub-samplers are tracking the output of the first sampler at any point in time. A third embodiment further includes generating third samples from the second samples at a rate of Fs/N, and having a relative phase of approximately ((360/N)*(i-1)+180) degrees. A method of interleaved analog to digital converting includes corresponding time interleaved ADCs receiving the third samples.

    摘要： A biasing scheme for a MOSFET that mitigates the MOSFET body effect. The biasing scheme can be realized replicating the voltage at the source terminal of a MOSFET and applying this replicated voltage to the body terminal. In this manner, the effect of the body transconductance, at high frequencies, becomes a function of the ratio of the well-to-substrate capacitance of the MOSFET to the sum of the well-to-substrate capacitance and the source-to-body capacitance of the transistor. At high frequencies, the biasing scheme mitigates the reduction in gain of a source follower caused by the body effect of a driven MOSFET within the source follower, improves the stability of a feedback network established by a gain boosting amplifier and the driven MOSFET by contributing a negative half plane zero to the transfer function of the feedback network, and reduces the power consumed by the gain boosting amplifier.

    摘要： Systems and methods are provided for controlling predictive medical monitoring. A non-linear-predictive-guide model estimates a patient parameter that is used as a guide in a deep neural network for improving accuracy of estimation by the deep neural network. The guide model generates a guiding first estimated patient parameter based on the guide model and patient input data. The deep neural network generates a second estimated patient parameter based on the deep neural network, the patient input data, and the guiding first estimated patient parameter. The deep neural network includes an input layer that receives the guiding first estimated patient parameter, and hidden layers including respective artificial neurons configured to perform a linear or nonlinear transformation on output of at least one artificial neuron from an adjacent layer in the deep neural network. An output layer receives at least one output from a hidden layer.
