  • Post payment processing tokenization in merchant payment processing
    Patent number: 12561674
    Abstract: Systems and methods for payment processing include receiving, by a payment terminal, a personal account number to complete a payment. The personal account number is encrypted by the payment terminal. The encrypted personal account number is sent from the payment terminal to a merchant server via a network. The encrypted personal account number is sent from the merchant server to a tokenization service provider server for tokenization and validation via a payment processor. The merchant server receives an indication of whether the transaction was successful and a token from the tokenization service provider server.

  • Cold-field-emitter electron gun with self-cleaning extractor using reversed e-beam current
    Patent number: 11830699
    Abstract: An e-beam device includes a cold-field emission source to emit electrons and an extractor electrode to be positively biased with respect to the cold-field emission source to extract the electrons from the cold-field emission source. The extractor electrode has a first opening for the electrons. The e-beam device also includes a mirror electrode with a second opening for the electrons. The mirror electrode is configurable to be positively biased with respect to the extractor electrode during a first mode of operation and to be negatively biased with respect to the extractor electrode during a second mode of operation. The extractor electrode is disposed between the cold-field emission source and the mirror electrode. The e-beam device further includes an anode to be positively biased with respect to the extractor electrode and the cold-field emission source. The mirror electrode is disposed between the extractor electrode and the anode.
