  • Publication number: 20200346199
    Abstract: The present disclosure is related to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst and, more specifically, to a method for preparing a gaseous- or liquid-nitridation treated core-shell catalyst comprising steps of: nitridation-treating a transition metal precursor core and noble metal precursor shell particles in the presence of a gaseous nitrogen source; or forming a transition metal precursor core and noble metal precursor shell particles, by means of a liquid nitrogen source, and at the same time allowing the nitrogen source to bond with the transition metal precursor and thus allowing nitridation treatment. Therefore, the present disclosure allows a high nitrogen content in the core and thus enables a prepared catalyst to have excellent durability, a small average particle size and high degree of dispersion and uniformity, and thus to be suitable for the fuel cell field.

  • Publication number: 20200019955
    Abstract: A magnetic secure transmission system includes an inductor, a switching circuit connected to the inductor, and a control circuit. The control circuit controls the switching circuit to adjust a level of a current in the inductor by a first amount over a data transmission period, such that the inductor emits a magnetic pulse including a first magnitude during the data transmission period. The control circuit controls the switching circuit to adjust the level of the current in the inductor such that the level of the current is increased and decreased repeatedly by a second amount between two different levels during a data non-transmission period, and the inductor emits a magnetic pulse including a second magnitude during the data non-transmission period. The second amount is less than the first amount, the first magnitude is greater than a threshold value and the second magnitude is less than the threshold value.

  • Patent number: 10430701
    Abstract: A magnetic secure transmission (MST) system includes a switching circuit, an inductor, and a control circuit. The control circuit is configured to control the switching circuit to adjust a level of current in the inductor. The inductor current may be adjusted by a first amount over a data transmission period such that the inductor emits a magnetic pulse including a first magnitude. The inductor current may be kept constant during a first sub-period of a data non-transmission period and may be changed by a second amount at a constant slope during a second sub-period of the data non-transmission period, such that the inductor emits a magnetic pulse including a second magnitude during the second sub-period of the data non-transmission period. The second amount is less than the first amount. The first magnitude is greater than a threshold value. The second magnitude is less than the threshold value.

  • Patent number: 6614477
    Abstract: Image capture data is output from an image capture device, e.g., a CCD, at a commanded frame rate. A succession of fields that occur at a field rate are identified. A commanded frame rate that is less than or equal to the field rate is received. Read signals are applied to the image capture device for selected fields of the succession of fields to thereby output image data at the commanded frame rate. The image capture device is shuttered for a shutter interval based on the commanded frame rate to prevent image capture during the shutter interval. According to aspects of the invention, the commanded frame rate is selected such that the field rate is an integer multiple of the commanded frame rate. An image capture apparatus according to the present invention includes an image capture device configured to receive read signals and operative to output image data responsive thereto. A timing generator is operative to produce a timing signal that define a succession of fields that occur at a field rate.
