  • Patent number: 9183553
    Abstract: A once card transaction system comprises a once card embedded with a once card number generator. The embedded once card number generator is able to communicate a once card number with a swipe card reader through the magnetic stripe emulator interface on the back of the card for in-store transaction or display it at the front of the card for online transaction. The embedded once card number generator is capable of generating an unpredictable once card number inside the once card without communicating with a central server. This distributedly generated once card number can be approved by an authentication entity by a valid OCN hashing list, and once the number is transacted, it is put on a rejection list.

  • Patent number: 9158951
    Abstract: A laser scanning module employs a scan mirror and magnet rotor subassembly supported by a stationary stator structure. The scan mirror and magnet rotor subassembly includes: a silicone frame having a pair of silicone torsional hinges (i.e. posts) aligned along a scan axis and a supported by a pair of support elements associated with the stator structure, to support the scan mirror and magnet rotor subassembly. When the scan mirror and magnet rotor subassembly is rotated about its scan axis, by forces generated by an electromagnetic coil structure acting on the permanent magnet mounted on silicone frame, the silicone torsional hinges are elastically distorted and generate linear restoring forces which return the rotor subassembly back to its home position about the scan axis.
