  • Publication number: 20170278376
    Abstract: A sensor for sensing a usage status of an electrical device and its associated method are disclosed. The sensor is disposed at a near-end of a power line of the electrical device. The sensor provided with a magnetic detector, an analog-to-digital converter and a controller. The magnetic detector is close to the power line to detect a magnetic field change around the power line to correspondingly generate an analog signal. The analog-to-digital converter (ADC) is used to receive the analog signal and convert the analog signal to a digital signal. The controller is used to receive the digital signal and generate an indication signal to accordingly learn at least one of statuses of being turned on and turned off the electrical device.

  • Patent number: 9664084
    Abstract: An emission reduction system is provided. The emission reduction system includes a tank configured to store a reductant. The emission reduction system also includes a pump configured to draw the reductant from the tank and supply the reductant to an exhaust system. The pump is further configured to draw in air from an ambient air source. The emission reduction system further includes a control assembly disposed in fluid communication with the ambient air source and the pump. The control assembly is configured to selectively allow the pump to access the ambient air source for purging the pump.

  • Patent number: 8889227
    Abstract: A method for preparing monolithic catalyst washcoat is disclosed and includes the following steps: preparing a coating slurry; pretreating a monolithic carrier; applying the coating slurry onto the monolithic carrier by vacuum spraying; removing the excess coating slurry by vacuum extraction; and obtaining the monolithic carrier applied with the washcoat after drying and calcination. The washcoat of 5-20 wt % can be obtained on the monolithic carrier of the present invention by one-off applying. The method can be used to prepare the washcoat on monolithic cordierite ceramic carrier, monolithic metal carrier, monolithic active carbon carrier or monolithic molecular sieve carrier. The obtained washcoat is uniform, and has good adhesion with the carrier and excellent repeatability.

  • Publication number: 20140108363
    Abstract: Embodiments of the present invention provide an encoding/decoding processing method, an encoder/decoder, and a terminal. The method includes determining whether a field in a file is a locally recognizable field. If the field is not a locally recognizable field, the method includes acquiring a field display identifier of the field, where the field display identifier is a content identifier of the field displayed by an application to a user, and decoding the field according to the field display identifier. According to the technical solutions in the embodiments of the present invention, it can be ensured that data is not lost in a process of exchanging a VCard file, thereby improving efficiency of exchanging the VCard file.

  • Patent number: 8207078
    Abstract: A close coupled three-way catalyst for purification of exhaust gas of motor vehicle and the preparation thereof. The support is selected from cordierite honeycomb ceramic materials having a pore volume of 0.25-0.35 ml/g. The coating layer is the mixture of hexaaluminate and perovskite-type composite oxide, cerium-zirconium solid solution, rare-earth oxide and alumina, alkali-earth oxide and zeolite having a high Si/Al ratio. The active components are palladium-rhodium, rare-earth oxide and transition metal in the hexaaluminate and perovskite-type composite oxide. The catalyst has not only the function of low-temperature catalytic oxidation of hydrocarbons, but also the function of reduction of nitrogen oxides, and can be used for purifying the exhaust gas of motor vehicles using gasoline, liquid gas, or CNG as fuel.

  • Patent number: 7121189
    Abstract: A valve for a fluid circuit is disclosed. The valve has a main valve element with a first end and a second end. The main valve element is movable between a flow-passing and a flow-blocking position in response to fluid pressure exerted on the first and second ends. The valve also has a solenoid mechanism operatively associated with the main valve element to move the main valve element toward one of the flow-passing and the flow-blocking positions. The valve further has a main valve spring configured to bias the main valve element in opposition to movement caused by the solenoid mechanism. The valve additionally has a relief valve element configured to communicate a fluid with the first end of the main valve element in response to a fluid pressure to initiate movement of the main valve element.
