    摘要： A dental appliance including a concave trough conforming to a plurality of teeth when placed over the plurality of teeth. The concave trough is configured to transition from a first shape to a second shape if a deforming force is applied. The concave trough further includes a shape memory material. The shape memory material is configured to restore the concave trough to an approximate first shape upon an application of an external stimulus. The first shape is configured to apply a first force on a tooth when the trough conforms.

    摘要： A system for generating digital postage stamps wherein a PC requests digital postage stamps from a data center. The data center generates a digital book of postage stamps, which the PC downloads to its hard drive. The digital book of postage stamps includes a read-only software module that prints each digital postage stamp using stamp related information contained within the software module. The software module on the PC verifies that the signature of the PC is identical to the PC signature that was stored in the software module when the software module was configured at the data center. If verified, the software module generates the digital postage stamp and then initiates printing on a printer coupled to the PC. The software module renders the data associated with the digital postage stamp being printed unusable for subsequent generations of digital postage stamps.

    摘要： A method and system for providing controlled access to information stored on a smartcard. The system includes a data processing center maintained by a trusted third party for storing a database of authorizations of various service providers to access information pertaining to individuals, and for responding to request by service providers for access from terminals which communicate with the data processing center and smartcards storing the individuals' information. The information is stored on the smartcard in encrypted form and the data processing center provides an access code, which includes a key for decrypting the information, only to service providers who are authorized to access the information. The service provider then sends the access code to the smartcard which verifies the access code and decrypts and outputs the requested information. The smartcard then computes a new key as a function of information unique to each access session and uses the new key to re-encrypt the information, and then erases the new key. The data processing center also computes the new key so that the data processing center can provide an access code including the new key for the next request for access.
