Disclosed is a non-volatile memory cell including a first conductive electrode region, a second conductive electrode region and a memory region disposed therebetween. The memory region includes one or a plurality of metal oxide nanoparticles, which contact and electrically connect the first and the second electrode region via contact locations and which exhibit a bistable resistance properties when applying an external voltage.

A decoding system, with a decoding engine, runs on a mobile device. The decoding engine decodes signals produced from a read of a first party's financial transaction card. The decoding engine accepts and initializes incoming signals from a read of the first party's financial transaction card until the signals reach a steady state, identifies peaks in the incoming signals and digitizes the identified peaks into bits. A transaction engine is coupled to the decoding engine. The transaction engine receives, as its input, decoded first party's financial transaction card information from the decoding engine, and serves as an intermediary between the first party and a second party. The first party does not have to share his / her financial transaction card information with the second party. The transaction engine is configured to be coupled to a payment system and a first party's financial transaction card institution or a first party's financial account.

The invention discloses a dense core permeability measuring device and method. The dense core permeability measuring device comprises a core holder, a standard gas mixture supply system, a confining pressure pump, a vacuum pump, a gas chromatograph and a thermostat, wherein an air inlet end of the core holder is connected with the standard gas mixture supply system through a pipeline. The method for measuring the dense core permeability of the dense core permeability measuring device comprises the following steps: S1, placing a rock sample to be measured with a length L into a rock sample cavity, and performing vacuum pumping on the rock sample and gas in the device by using the vacuum pump; and S2, starting the confining pressure pump, increasing the confining pressure of a confining pressure cavity to a required confining pressure value, and keeping the pressure constant. Through adoption of the dense core permeability measuring device and method, the problems of difficulty in measuring flow and no consideration of dispersion and slip in the process of measuring the permeability with the existing steady state method are solved.

The invention discloses a constant pressure water supply system. The system comprises a central processing unit. An input end of the central processing unit is connected with an output end of a signaltransmitting-receiving module through a local area network by bidirectional signals. The input end of the signal transmitting-receiving module is electrically connected with the output end of a display panel in a bidirectional manner, and the output end of the display panel is electrically connected with the input end of a buzzer. The input end of the central processing unit is electrically connected with the output end of the input module. Through arranging the central processing unit, a first pressure sensor, a second pressure sensor, and a third pressure sensor, when the constant pressurewater supply system supplies water, a steady-state value of pressure, super high pressure, and super low pressure are respectively detected. Through arranging a control node module and a water supplymodule, when water pressure does not meet requirement, water pressure can be adjusted in time, so that when the water supply system provides a water source, the water pressure can maintain constant, and a device can work normally, so as to improve production efficiency and reduce production cost.

The invention discloses a low-speed delay on-time setting method for a brushless DC motor. The setting method includes setting that initial value of start-up phase delay opening time to 0 after brushless DC motor enter low-speed steady-state working state, ; in each subsequent commutation cycle, the on-phase delay on-time is incremented by one microsecond; Recording the rotational speed Sa of thebrushless DC motor before commutation of each commutation cycle; Brushless DC motor speed Sb in each commutation cycle is record; Subtracting the Sb from the Sa to obtain the rotational speed deviation Delta S of the brushless DC motor; The on-phase delay on-time corresponding to the minimum absolute value of Delta S / Sa is taken as the setting value of the low-speed delay on-time of the brushlessDC motor.
