A first phase change material layer vertically aligned above a bottom electrode, a filament layer vertically aligned above the first phase change material layer, a second phase change material layer vertically aligned above the filament layer, an inner break in the filament layer connecting the first phase change material layer and the second phase change material layer, a top electrode vertically aligned above the second phase change material layer.

Abstract: A resistive random access memory device comprises: a bottom electrode; a bottom layer of dielectric material formed on the bottom electrode; a plurality of conductive contacts extending from the bottom electrode through the bottom layer of dielectric material; a top layer of dielectric material formed on the bottom layer of dielectric material and on the conductive contacts; a top electrode on the top layer of dielectric material; and at least one filament extending from the plurality of conductive contacts through the top layer of dielectric material to the top electrode.

Abstract: A method and device for issuing an identity certificate to a blockchain node in a blockchain network includes issuing a first identity certificate to a first terminal. a second identity certificate issuance request that is from the first terminal and that is made by using the first identity certificate is received and a second identity certificate is issued to the first terminal, which forwards the second identity certificate to a second terminal. A third identity certificate issuance request that is from the second terminal and that is made by using the second identity certificate is received and a third identity certificate is issued to the second terminal, which forwards the third identity certificate to a third terminal.

Abstract: A one-touch data transmission module includes a data receiving unit, for receiving a transmission datum sent by a physiological data analyzer; a control unit, electrically connected to the data receiving unit, for obtaining the transmission datum received by the data receiving unit; a memory unit, electrically connected to the control unit, for storing the transmission datum; a communication unit, electrically connected to the control unit, for sending the transmission datum to a designated place; a power unit, for supplying power to the data receiving unit, the memory unit and the communication unit; a trigger button, electrically connected to the control unit, for triggering the control unit to start the data receiving unit to receive the transmission datum, the received transmission datum being send by the communication unit. The data transmission module provides the functions of simple operation and real-time data transmission for an elderly person.

Abstract: A coaxial connector (100) adapted for mating with a mating connector (200) includes a bracket (10), and a clasping portion (40) clasping the mating connector. The bracket has a central contact (30) retained in the bracket for electrically connecting with the mating connector. The clasping portion includes a base flange (41) and a number of claw portions (42) extending from the base flange. Each claw portion has an engaging portion (421) for engaging with the mating connector. The coaxial connector further includes a resilient ring (70) mounted on the engaging portion of the clasping portion to strengthen the engagement between the engaging portion and the mating connector. The coaxial connector includes a conductive resilient sealing ring (60) mounted between the bracket and the mating connector.

Abstract: An RF connector (1) for mating with a plug connector (3) has an outer housing (1) defining an axial bore (101) for receiving the plug connector, a locking member (14) received in the axial bore, an insulative body (12) retained in the axial bore of the outer housing and defining an axial hole (121), a terminal (13) assembled to the axial hole of the insulative body, a first sealing ring (15) and a second sealing ring (16). The first sealing ring is assembled between an interior surface of the outer housing and an outer surface of the locking member. The second sealing ring is disposed around an inner surface of locking member for resisting against an outer surface of the plug connector when the plug connector is inserted in the RF connector.
