    Abstract: Systems (100) and methods (600) for making a marker. The methods comprise: obtaining a resonator material which has been annealed under a tensile force selected to provide a maximum resonant amplitude at a bias field Hmax in the marker; and providing with the bias material of the marker an operating bias field Hoperating with a value less than a value of said bias field Hmax. The value of Hoperating is reduced by performing at least one of the following operations: selectively modifying a geometry of a bias material which is to be disposed in a housing of the marker; selectively modifying a spacing between the resonator material and the bias material arranged in a stacked configuration; and partially de-gaussing the bias material subsequent to being fully saturated.

    Abstract: A driving circuit for driving electronic paper is provided, which includes a plurality of driving units. Each driving unit couples to display units of a row of the electronic paper through a data terminal for driving a display unit from a previous gray level to a target gray level during a driving period. Each driving unit includes a data driver and a switch. The data driver respectively provides a black data DC voltage and a white data DC voltage to the data terminal during a black phase and a white phase of the driving period, and provides a first pulse and a second pulse to the data node during a program phase of the driving period. The switch conducts the data node to a middle voltage between the first pulse and the second pulse.

    Abstract: A video compression circuit including a video pre-processor, a macroblock data storage unit and a video processor is provided. When fulfilled by an input video signal, the video pre-processor converts the input video signal to generate a macroblock data. The macroblock data storage unit alternatively and temporally stores the macroblock data generated from the video pre-processor. The video processor alternatively reads the macroblock data stored in the macroblock data storage unit, and compresses the readout macroblock data to an output video signal.

    Abstract: A water quality control method for an evaporative cooling water chiller uses a water pump to transport cooling water from a water tank to a water-spraying element via a water pipe. The cooling water is sprayed onto fins and a refrigerant pipe of a first heat exchanger, flows along the fins and is collected in the water tank. Thereby, the cooling water reduces the temperature of the heat exchanger. The water pump is set to operate for a first period and to stop for a second period so that the temperature of the fins and the refrigerant pipe increases. Thereby, the limescales attached to the heat exchanger are detached and drop into the water tank. Subsequently the water pump is turned on again. The cooling water in the water tank flushes out the accumulated particles on the bottom of the water tank, and clean cooling water is added.
