Abstract: A liquid dispensing element is provided. The element comprising; a dispensing plate comprising a plurality of orifices; the dispensing plate at least partially defining a fluid flow path; a plurality of piezoelectric transducers each comprising a piston configured to move perpendicular to the dispensing plate between a first position wherein the piston is close to the dispensing plate and a second position wherein the piston is further from the dispensing plate. The movement between the first and second positions results in the ejection of a droplet of fluid via a surface cavitation droplet ejection process such that the diameter of the droplet is less than a diameter of the orifice.

Abstract: The present invention relates to secure transmission and reception of electronic messages using an authentication device. The authentication device includes a light sensor that is used to scan a visual element displayed on a display of a user device in conjunction with an electronic message having an encrypted payload. The visual element encodes a unique identifier that the authentication device transmits to a server, receiving in response a cryptographic key stored in association with the unique identifier and usable to decrypt an encrypted payload of the electronic message. The authentication device can also generate encryption keys and corresponding unique identifiers suitable for encryption of payloads of electronic messages.

Abstract: When Integrated Circuit Cards (ICC's) such as chip cards are configured to initiate electronic transactions, such as financial transactions, lapses in security can have severe consequences. Although global standardization means a high degree of interoperability, it also means that ICC's may be manufactured anywhere in the world. A frequent problem is that ICC's with older generation IC's remain in circulation, and/or some manufacturers of ICC's may use older technologies in new cards. Both of these policies may increase the security risks. In addition, ICC's can be cloned, and may be difficult to distinguish from genuine ICC's. By providing a card reader with a signal generator for providing a circuit test signal, and a signal detector, for detecting a circuit response signal, the response signal may be compared with an expected response signal to determine a degree of electrical correspondence and whether the ICC passes or fails the hardware integrity control.
