  • Patent number: 7376432
    Abstract: A paging transceiver and method for selectively paging provides a page to a paging transceiver but does not automatically provide an associated message. The paging transceiver receives the page and alerts the user that a message is waiting and preferably provides a short description of the message. The user can then download or otherwise act on the message at a time and at a place convenient to the user. The user can therefore place the paging transceiver in a location where it can easily receive and reply to the message. The paging system conserves air time and the paging transceiver conserves memory by not automatically receiving the associated messages. The user can determine the time at which the paging transceiver receives transmissions, such as during off-peak hours. The messages stored by the systems and delivered to the paging transceiver may be of different types, such as voice, text, audio, or even video.

  • Patent number: 7376073
    Abstract: Theft, distribution, and piracy of digital content on optical media (software, video, audio, e-books, any content of any kind that is digitally stored and distributed) is often accomplished by copying it directly to another disc using commonly available copy tools and recordable optical media, or the copying of media to another mass manufactured disc. Methods which cause the copy process to become lengthy and inconvenient, or which produce copies that are significantly measurably different from the original and therefore be recognizable as copies, deter or prevent an unauthorized individual from making copies. This is accomplished by modifying the optical path of an optical medium to include regions of selective distortion. This, in turn, modifies the read operation of the data in the regions, which can be used to identify and authenticate the medium.
