    摘要： Methods and circuits for power supply arrangement and control are disclosed herein. In one embodiment, a switching regulator can include: (i) a filter network coupled to an output terminal, where an output voltage is generated at the output terminal from an input source; (ii) an active switch to connect the input source to the filter network by periodically operating between on and off states over a switching period, where a duty cycle of the on state relative to the switching period is modulated based on a PWM control signal; (iii) a comparator receiving an output feedback signal, a hysteresis signal, and a reference level, and providing the PWM control signal therefrom; and (iv) a hysteresis programming circuit generating the hysteresis signal, and a ramp control signal, where the hysteresis signal is programmed based on conditions at the input source and the output voltage to achieve a pseudo constant frequency operation.

    摘要： A multiple-cell battery includes a battery case and a number of cells positioned in the battery case. Each of the cells includes a positive lead and a negative lead. A number of electrically conductive elastic elements are correspondingly seated between every two adjacent positive leads and/or negative leads. The elastic elements each include at least two contacting portions resiliently abutting against the two adjacent positive leads and/or negative leads, so as to connect the cells in series and/or in parallel.

    摘要： The present invention discloses a key device for a mobile phone, which comprises a printed circuit board (PCB), a key disposed on the PCB and a metal dome disposed above the key. The metal dome is able to make electrical contact with the key. The key comprises a first electrode, a second electrode and a third electrode, and the third electrode is formed as two rings in which the first electrode and the second electrode are disposed respectively. In the key device for a mobile phone provided by the present invention, the key is formed with three electrodes, so when the metal dome makes contact with the first electrode or the second electrode, the three electrodes of the key are electrically connected with each other simultaneously. This imparts the key for a mobile phone with the compatibility, thereby reducing the product cost and shortening the duration of research and development.

    摘要： Activation of electrogenic pump molecules can be realized by a dynamic entrainment procedure which includes two steps: synchronization of individual pump molecules to work at the same pumping pace, and gradual modulation of the synchronization frequency. Na/K pump molecules were used as an example in a physiological operating mode by applying the concept of an electronic synchrotron to the biological system. It was shown that individual Na/K pump molecules can be synchronized by a well designed oscillating electric field. The synchronized pump currents show separated inward and outward pump currents and a magnitude ratio of 3:2 reflecting stoichiometric number of the pump molecules.

    摘要： A molecular detection device for use in electrochemical detection assays includes at least two electrodes, and has a film deposited on at least one of the electrodes. The film includes a conductive polymer and conductive particles, having mean diameters between 1 and 100 nm, within the conductive polymer. Probe molecules may be attached on or to the conductive polymer, or be included in the conductive polymer. The device may be used to detect specific target molecules in a sample, for example, protein, peptide, nucleic acid or small molecule target molecules.
