摘要:
A Postal Authority regulated e-Mail messaging application is provided over a public network to a plurality of mailers and addressees using authenticated transaction records. The application transmits at least one e-Mail message through at least one e-Mail account configured for a specific class of service. The application creates transaction records relevant to the specific class of service based upon details of completed transactions. Electronic postmarks are obtained to authenticate transaction records. Authenticated transaction records are sent to the mailer. A unique identifier of an electronic postmark is embedded in the e-Mail message. The e-Mail message incorporating the unique identifier is sent to at least one addressee. Authenticated e-Mail messages and transaction records are created and protected from undetectable modification.

A method and apparatus provide digital receipts for third-party electronic commerce transactions, using a Web Receipt Service. The digital receipts can be used to validate the details of electronic transactions carried out over public networks such as the Internet. A Web service provides a digital receipt comprising a transaction record identifying transaction details. The transaction record is sent to the Web Receipt Service, where a computer controlled by the Web Receipt Service digitally signs and encrypts the record. The transaction record is encrypted such that it may be later decrypted only by the Web Receipt Service and cannot be altered by others. A digital receipt is formed comprising the encrypted transaction record, which may be embedded in a graphic using steganography to enable display in a Web page. The digital receipt containing the encrypted transaction record is returned electronically to each of the parties to the transaction. The digital receipt may be formed in real-time, so that it can be made an integral part of the electronic commerce transaction. The Web Receipt Service need not store the digital receipts. Each party may later present the digital receipt to the Web Receipt Service for verification. The Web Receipt Service decrypts the transaction record and returns the transaction record so that the parties may then compare the decrypted transaction record to any previously stored version they may possess.

The present invention provides an ergonomic mobility chair comprising a frame, two primary wheels and at least one secondary load-bearing rolling point device. The primary wheels are usable for hand propulsion of the chair and positioned forward of the center of gravity of the chair. The primary wheels are mounted on a collapsible axle structure coupled to the frame. The at least one secondary load-bearing rolling point device is positioned aft of the center of gravity of the chair and coupled to the frame. A seat and two knee supports are coupled to the frame, the seat and the knee supports being arranged with respect to one another so as to position a user of the chair in a kneeling, upright, and generally neutral physiologic position. The seat and the knee supports each comprise at least a comfort cushion support coupled to the frame of the chair.
