  • Patent number: 10404462
    Abstract: Embodiments described herein combine both glyph technologies and cryptography technologies by encrypting data with a private key of an entity tasked with issuing controlled documents, and then converting the resulting encryption as a visual glyph, such as a QR code. This permits validation of the printed document by scanning the QR code using a smartphone and decrypting using the issuing entity's public key. In some embodiments, a purpose-built software application executed by the smartphone may automatically recognize QR codes on a document presented for review and then automatically decrypt the QR code using the public key of the issuing entity. A user performing the validation may then compare the document's content with the decrypted data on the smartphone.

  • Patent number: 6600814
    Abstract: A messaging system comprises a storage unit for storing e-mail messages, a text-to-speech converter for converting the different text segments of e-mail messages into speech signals for playback to a user via a telephone handset, and a cache for storing the speech signals of selected ones of previously converted text segments. Upon a subsequent request by a user to convert the text segments of a new e-mail message to speech signals for playback via a telephone handset, the speech signals of previously converted text segments that are identical to any text segments of the new e-mail message are played back from the cache thus avoiding the need for the text-to-speech converter to convert those text segments of the new e-mail message to speech. The load on the text-to-speech converter is thereby reduced.

  • Patent number: 5225197
    Abstract: A chewable tablet comprises a medicament dispersed in a chewable base, such as mannitol, together with an effervescent couple, such as citric acid - sodium bicarbonate. The combination of effervescence and chewability with optional flavorings improves the taste characteristics of the medicament in oral adminstration. A disintegrant such as microcrystalline cellulose may be added to give the patient the option of dispersing the tablet in water.
