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.

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.

Abstract: The invention relates to an anhydrous composition comprising a vasodilator and an acceptable carrier wherein the vasodilator is present in an amount effective to increase the blood flow when the composition is applied to human tissue. The compositions according to the invention are non-flushing.

Abstract: The invention relates to a method of attaining enhanced sexual wellness of an individual comprising administering to the genital areas of the individual, an anhydrous composition comprising a vasodilator, for example, a niacin derivative, and an acceptable carrier. The method according to the invention does not cause flushing.
