Abstract: Systems and methods for managing digital rewards for users associated with completion of product reviews by the users. According to certain aspects, a server determines that a user purchased a given product, and offers a digital reward to the user for completing a review of the given product. An electronic device enables the user to complete the review and communicates the review to a digital repository that avails the review for use by a website. The server interfaces with the digital repository to determine that the user completed the digital review, and applies the digital reward to an account of the user.

Abstract: The invention provides a system for distributing a text document (101) comprising: a data conditioning system (102) including: a data receiver for receiving the text document (101) in a received document format; and a conversion system for converting the text document (101) from the received document format to text data in a standardised text-to-speech format; and a transmission system (105) for transmitting the text data in the standardised text-to-speech format, whereby a receiver (109), including a text-to-speech converter, can be used for converting the text data into speech.

Abstract: A sterilization apparatus wherein one or more electron beam tubes are used to direct electron beams into an ambient gaseous environment to create an electron plasma cloud into which non-sterile target objects may be moved. The electron plasma cloud is formed by interaction of the electron beam with the ambient atmosphere. Helium or other like gaseous may be used to expand the effective volume of the electron plasma cloud. Manipulators are used to move target objects in the electron plasma cloud, exposing non-sterile surfaces to the cloud and then joining the surfaces together where appropriate. The beam tube used to generate the electron beam has a thin low energy absorbing window which allows relatively low energy beams to be used, minimizing damage to materials within the surface of the target objects.
