    摘要： A system and methods for the efficient segmentation of globally optimal surfaces representing object boundaries in volumetric datasets is provided. An optical surface detection system and methods are provided that are capable of simultaneously detecting multiple interacting surfaces in which the optimality is controlled by the cost functions designed for individual surfaces and by several geometric constraints defining the surface smoothness and interrelations.

    摘要： An electrical circuit whose slow rate can be changed. Included in the circuit is an input node for applying a voltage signal, a first switch in series with the input node, and a resistance in series with and in-between the input node and first switch. The slew rate of the circuit is adjusted by changing the equivalent resistance between the input node and the first switch based upon a control signal.

    摘要： A PWM current control circuit that determines whether a start-up time, during which an decreased current is being drawn, for a load has elapsed and providing a switch that supplies current to the load with a control signal that limits the current being drawn if the start-up time has not elapsed and providing a standard PWM control signal from a microcontroller if the start-up time has not elapsed. Excessive inrush current during the start-up period of the load is avoided while the current is maintained to be within a predetermined range during start-up and after the start-up time has elapsed the control is again turned over to the microcontroller.

    摘要： A system and method for detecting the presence of a voltage on a ground conductor which is coupled to a protective Earth (PE) terminal associated with a power source. The power source is used to apply a voltage to a device. The system may use a high impedance device coupled across a switch, with the switch being in communication with a portion of the device. A control system may monitor a voltage across the high impedance device and determine if the voltage across the high impedance device exceeds a predetermined threshold. Exceeding the predetermined threshold indicates that an unsafe voltage from the power source is present on the ground conductor. A natural high impedance path between the device and the Earth is used to provide an Earth connection through the device to the Earth during operation of the system.

    摘要： Methods, systems, and media are provided for identifying languages in multilingual text. A document is decoded into a universal representative coding for easier tag manipulation, then broken into plain-text content sections. The sections are identified and assigned a weight, wherein more informative sections are given a higher weight and less informative sections are given a lesser weight. A language likelihood score is determined for each word, phrase, or character n-gram in a section. The language likelihood scores within a section are combined for each language. The combined section scores are then summed together to obtain a total document score for each language. This results in a document score for each language, which can be ranked to determine the primary language for the document.
