Output control method for a digital controller of a source measure unit
An output control method for a controller includes the following steps. At each of detection time points, the controller detects a detection voltage value and a detection current value of a load. In a voltage control mode, the controller generates a setting parameter to control the power amplifier according to part of the detection voltage values. In a current control mode, the controller generates the setting parameter to control the power amplifier according to part of the detection current values. When the controller switches to the voltage control mode or the current control mode, the controller determines a ratio between the detection current value and the detection voltage value at one of the detection time points and the setting parameter is generated according to the ratio. Therefore, the bandwidth is substantially the same no matter if the controller operates in the voltage control mode or the current control mode. |

Interactive outline as method for learning
Systems and methods for learning one or more subject areas. The methods may comprise an interactive outline learning system, in which the subject area may be organized into one or more multi-layered outlines, and lines may connect elements in each layer with related elements in adjacent layers. Each layer of the outline may correspond to one or more steps in the analysis of a question presented about the subject area. The systems may include a user interface component which may receive input comprising a first selection of an element from the first level of the outline, and then selections from subsequent layers of the outline. The methods may include determining whether each selection correctly corresponds with a step in the analysis of the question, and may visually indicate the correct element and/or connecting lines in response to a correct selection. |

Predictive recommendation engine
Computer processes, systems and methods for alerting a student device when an objective is mastered according to a piecewise Gaussian distribution updated according to a Bayesian method are disclosed herein. The system can include a student device having a network interface to exchange data with a server via a communication network, and an I/O subsystem to convert electrical signals to user interpretable outputs user interface. The system can include a server that can: receive a student identification; retrieve the next learning objective; determine the difficulty level of the next objective problem set; and determine the probability of the student correctly answering the problems in the problem set. The system may also include a teacher device. |
