Publication number: 20230223714Abstract: The embodiments of the present utility model provide a spring leaf, a connection terminal, and an electrical connector, where the spring leaf is provided in a cylindrical housing in a winding manner, and extends outward from a first end to form hangers extending out of the housing. The spring leaf is hung on an end portion of the housing through the hangers, and then the hangers are fixed through an end cover arranged at the end portion of the housing. Thus, the first end of the spring leaf may be fixed through the hangers, and a second end of the spring leaf may move automatically. When a pin is inserted, the compressed spring leaf will not be dislocated, which ensures the contact reliability of the pin with the spring leaf.Type: ApplicationFiled: January 9, 2023Publication date: July 13, 2023Applicant: Xuancheng Luxshare Precision Industry Co.,LtdInventors: Shuguang CHEN, Rongxin SHEN, Wei GAO, Qi YANG, Chongyang ZHONG, Guangyu XI

Patent number: 10879613Abstract: Various embodiments are described that relate to patch antenna elements and parasitic feed pads. A patch antenna element can have a resistance and reactance. The resistance can be desirable while the reactance can be undesirable. To counteract the reactance, a parasitic feed pad can be placed near the patch antenna element and the parasitic feed pad produces a capacitance. The capacitance balances out the reactance to cancel out one another. When two patch antenna elements and two parasitic feed elements are employed in one antenna stack, the stack antenna can function as a dual band antenna.Type: GrantFiled: April 14, 2020Date of Patent: December 29, 2020Assignee: The Government of the United States, as represented by the Secretary of the ArmyInventor: Shuguang Chen

Patent number: 10186775Abstract: Various embodiments are described that relate to a patch antenna. Portions of a patch antenna, such as a patch antenna element and a probe feed wire can produce an impedance that is undesirable. To compensate for this, a parasitic feed pad can be aligned with the patch antenna element to create a capacitor. This capacitor produces a capacitance that negates the impedance. It can be preferred for the capacitance to be such that there is no excess capacitance and no excess impedance.Type: GrantFiled: August 11, 2015Date of Patent: January 22, 2019Assignee: The United States of America, as represented by the Secretary of the ArmyInventors: Timothy Bocskor, Shuguang Chen, Mahmoud Khalil

Patent number: 10079437Abstract: Various embodiments are described that relate to co-polarization between a first antenna and a second antenna. The first antenna and second antenna can be configured such that co-polarization between the two is increased (e.g., maximized) while cross-polarization is decreased (e.g., minimized). This can be accomplished by physical orientation of the first antenna against the second antenna and/or through powering the first antenna and second antenna differently with phase delay.Type: GrantFiled: September 28, 2015Date of Patent: September 18, 2018Assignee: The United States of America, as represented by the Secretary of the ArmyInventors: Shuguang Chen, Mahmoud Khalil, Timothy Bocskor

Publication number: 20180149272Abstract: Provided is a concave-plate triple eccentric butterfly valve, which includes a valve body, a upper valve stem, a valve seat, a valve plate, and a lower valve stem, among which the valve plate has a concave structure. When used in an isolation function application as well as in a fully open state, the valve plate is hidden behind the valve seat and the fluid passage of the valve is a smooth fluid passage, the valve can have a greater flow capacity. The flow of the fluid does not flush the valve plate sealing surface from the front. During the opening and closing process, the turbulence caused by the disturbance of the fluid is reduced and therefore the vibration of the system is reduced. In adjustment applications, the adjusting sleeve concave spherical surface, the adjusting sleeve fluid passage, and the valve plate convex spherical surface can cooperate to form the fluid passage adjusting opening.Type: ApplicationFiled: May 5, 2017Publication date: May 31, 2018Inventors: SHUGUANG CHEN, XINYANG LIU

Patent number: 9973291Abstract: Various embodiments are described that relate to a combined signal. A signal can be transmitted from a transmitter and be received by a receiver. The receiver can be an antenna array that comprises multiple individual antenna elements. At least some of these individual elements can receive the transmitted signal at different reception angles and these received signals can be considered signal copies. The reception angle can influence a power level of a signal copy. Multiple signal copies can be combined together into a combined signal that has a greater power level than the individual signal copies used in the combination.Type: GrantFiled: February 18, 2016Date of Patent: May 15, 2018Assignee: The United States of America, as represented by the Secretary of the ArmyInventors: Steven Goodall, Shuguang Chen
