Publication number: 20240068783Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.Type: ApplicationFiled: July 25, 2023Publication date: February 29, 2024Applicant: VIETTEL GROUPInventors: Anh Tuan Vu, Duc Thanh Nguyen, Van Duc Ha, Kim Duc Hoang, Thanh Nhon Nguyen, Anh Tra Duong, Tran Nam Nguyen

Patent number: 11345575Abstract: A clamping device for lifting and transferring objects can employ slanting interfaces to convert a pulling action on the clamping device to a clamping action on the object. A pulling element in the form of a triangle can be disposed between a jaw and a jaw support of the clamping device. When the pulling element is pulled up, the base of the triangle shape pulling element can exert a force on the jaw against the jaw support, for securing a gripping action on the object.Type: GrantFiled: February 26, 2018Date of Patent: May 31, 2022Inventor: Hoa Nhon Nguyen

Publication number: 20200070279Abstract: The patent presents a new method of damping for laser activation systems including five steps: Step 1: Locating, clamping the batteries, PCB; Step 2: Receiving hammering force; Step 3: Damping for batteries; Step 4: Damping for PCB; Step 5: Sliding electrical contact drive. This damping method has outstanding advantages in vibration suppression in different frequency ranges and amplitudes, along with applied damping according to the requirements and characteristics of each part. As a result, the two-level damping method improves stability and longevity of the laser activation system.Type: ApplicationFiled: August 23, 2019Publication date: March 5, 2020Applicant: VIETTEL GROUPInventors: VAN DUC HA, THANH NHON NGUYEN

Patent number: 8369165Abstract: A synchronous signal generating circuit. The synchronous signal generating circuit includes a delay locked loop (DLL), an emulator and a multiplexer. The DLL is operative to delay a reference clock signal according to a count value to generate a first output clock signal. The count value is generated according to phase difference between the first output clock signal and the reference clock signal. The emulator is operative to provide a function of the DLL and includes a programmable delay line which is operative to receive the reference clock signal and a reference count value, wherein the reference clock signal is delayed according to the reference count value to generate a second output clock signal. The multiplexer is operative to receive the first and second output clock signal and selectively output the first or second output clock signal. The first output clock signal is outputted in a first mode and the second output clock signal is outputted in a second mode.Type: GrantFiled: February 17, 2011Date of Patent: February 5, 2013Assignee: Nanya Technology CorporationInventors: Nhon Nguyen, Phat Truong, John Phan

Patent number: 7490882Abstract: A clamping device suitable for lifting and handling of sheet like-objects has a fixed jaw parallel to a movable jaw. The movable jaw is supported for reciprocating, linear movement towards and away from the fixed jaw responsive to a tensile actuating force. The movable jaw comprises a clamping plate inclined at an angle of about 8 to 12 degrees with respect to first and second clamping surfaces. The clamping plate maintains said angle during movement to and from the fixed jaw. A tensile force transmitting member is guided and supported at an upper location of the clamping plate that substantially aligns with or overhangs the second clamping surface.Type: GrantFiled: January 14, 2003Date of Patent: February 17, 2009Assignee: Abaco Machines (Australasia) Pty, LtdInventors: Hoa Nhon Nguyen, Hau Nhon Nguyen
