    • The present invention of damping segmental ring structure for subway tunnels built in grim environments of deformable ground can mitigate the stress-concentration of the tunnel lining structures. The deformable ground can be caused by differential settlement or high-intensity earthquakes. Embodiments of the invention have self-adjustment features and forms for deformation and rotation, which comprise one adapter in the middle, two transitional grooved segmental structures, and an internal steel tube. All three forms comprised 3 or 4 pieces with the same features so they can be easily installed, transported and erected on sites and bolts are used to bolt them together to form an integrity structure with damping characteristics. The damper placed in the middle comprises two loading plates that form the shell of the damper, the internal core of the damper which includes interbedded installed rubber pads and steel plates within the loading plates and spring systems that compress the internal core. The springs are locked to the loading plates using locking clamps and the loading plates are bolted to the transitional grooved segmental ring structures, and the transitional grooved segmental ring structures are bolted themselves in the circumferential direction to form a ring structure and bolted with the regular segmental ring structures in the longitudinal direction. The internal steel tube is concentric with the damper but has a smaller diameter so it can support the damper by fastening the counter-reaction bolts installed in the bent-up flanges of each piece. Waterproof anti-slippery rubber pads are placed in all interfaces between the damper, and the transitional segmental ring structure, the regular segmental ring structure and the internal steel tube. The invention of the damping segmental ring structure has self-adjustment capabilities for deformation and rotation whereas the stiffness remains sufficient to resist soil and groundwater pressure. The invented damping segmental ring structure can be manufactured in factories that manufacture the regular segmental ring structure and can be shipped to and installed on-site using the same equipment that installs the regular segmental ring structure. The internal steel tube provides double-safety for the stiffness of the damper and the supports can be adjusted during tunnel operations.

    • An enhanced encryption keypad (100) capable of preventing illegal disassembly for an automated teller machine comprises a key panel (101) and a main control board (102). A removal detection protection circuit is disposed inside a main chip of the main control board (102), and at least one pin of the removal detection protection circuit is guided out from a surface (1021) of a side of the main control board (102) near the key panel to form a removal detection point (1022). The removal detection point (1022) has two opened signal contact points. The two opened signal contact points are conducted by a conductive adhesive (103) to activate the removal detection protection circuit. A conductive protection ring (1023) isolated from the removal detection point is disposed at the periphery of the removal detection point. The conductive protection ring (1023) is connected to the removal detection protection circuit inside the main control chip. A protection circle (1024) is disposed at the periphery of the conductive protection ring and the corresponding conductive adhesive. The present application effectively protects the encryption keypad from illegal attacks on the removal detection point from the side.
    • 能够防止自动柜员机非法拆卸的增强型加密键盘(100)包括键盘(101)和主控板(102)。 移除检测保护电路设置在主控板(102)的主芯片的内侧,移除检测保护电路的至少一个引脚从主控板(102)侧的表面(1021)被引出 ),以形成移除检测点(1022)。 移除检测点(1022)具有两个打开的信号接触点。 两个打开的信号接触点由导电粘合剂(103)进行以激活去除检测保护电路。 从去除检测点隔离的导电保护环(1023)设置在移除检测点的周围。 导电保护环(1023)连接到主控芯片内部的去除检测保护电路。 保护圈(1024)设置在导电保护环的周边和相应的导电粘合剂上。 本应用有效地保护加密小键盘免受从侧面的去除检测点的非法攻击。
