    摘要： An exemplary voltage testing device includes a testing circuit and an oscillograph. The testing circuit includes a filtering unit, a rectifier unit, and a voltage dividing unit. The filtering unit receives and filters an alternating current (AC) voltage. The rectifier unit receives the filtered AC voltage and rectifies the filtered AC voltage into a first direct current (DC) voltage. The voltage dividing unit receives the first DC voltage, and dividess the first DC voltage into a second DC voltage equaling an effective value of the AC voltage, thereby the second DC voltage is tested and displayed on the oscillograph.

    摘要： Methods for debugging designs are provided. First, signal correlation information for signals of a design at least two design level is obtained. Then, design descriptions corresponding to the design at the at least two design levels are loaded and presented in at least two sets of windows or at least two debugging processes which controls the respective set of windows. A selection of a first signal in a first set of windows or a first debugging process is received. In response to the selection, a second signal corresponding to the first signal is queried according to the signal correlation information, and the second signal in a second set of windows or a second debugging process is automatically selected.

    摘要： To provide a fast and systematic selection of exercises for a training plan of a user, the invention proposes a method and device for selecting exercises, each of a plurality of exercises (E1 to E5) being associated with a set of characteristics, and each characteristic of the set of characteristics being associated with a set of categories (C1 and C2) for classifying the plurality of exercises, the method comprising the steps of: A. selecting, according to input reflecting answers to a first set of questions related to a given characteristic among said set of characteristics, a subset of categories (C1) from a set of categories (C1 and C2) which is associated with said given characteristic, wherein said answers to the first set of questions reflect information of said user; B. determining a set of exercises based on said selected subset of categories (C1). The method takes each category as a whole and selects proper categories, and then determines proper exercises from the exercises in the determined proper categories. The present invention enables the proper exercises to be obtained faster and more systematically as compared to selecting the proper exercise from a number of exercises by checking them one by one.

    摘要： A transceiver circuit having 10 mb and 100 mb transmit and receive circuitries using the power saving methods of the present invention is disclosed. The power consumption of the transceiver circuit can be significantly reduced by providing each defined subcircuit with its own power supply and means of activation and deactivation. However, the method for activating and deactivating digital subcircuits and analog subcircuits are different and therefore different types of control signals and methods are provided. Furthermore, there are two general types of power-saving situations. The first type is near total circuit power-down and the second type is partial circuit power-down. The present invention in yet another embodiment discloses a method for minimizing energy usage during idle period.
