Abstract: A door access control and key management system is disclosed, in which a number of doors and door users are involved. The system comprises a door/key administering system and a door lock/control assembly mounted on each door, which are communicatively interconnected with each other via a communications network. The door/key administering system serves to store a key unique to each of the users, store an identification code unique to each of the doors, and assign access authorization to at least one user for each door. The door lock/control assembly serves to read the key presented by the user, verify that the key has access authorization, and operate the door in response to the authorization for access. Each user can gain access to the doors authorized to the user with a unique key and each door can provide access to the user or users assigned thereto.
Abstract: A hosted system and method for user creation and update of a user Web, provides for customization of appearance and functionality of a user Web that is totally separate from the maintenance of the variable contents of a user Web. The hosted system and method of the present invention first generates a fixed default design for a user's Web site of at least one generic type of page and the linkages between this page and a Home Page. Thereafter, the hosted system provides capabilities for a user to perform multiple, generic types of customization of the appearance of a user Web from which both a ‘view’ and a companion ‘update’ Web page is generated for each user page. Any variable content of a ‘view’ page of a user Web is entered and updated by the user employing the ‘update’ Web page after the Web site has been generated and stored at a Host by the hosted system and method of the present invention.
Abstract: A data server for use in networks in which media signals are transmitted as digital signals in packet form comprises at least one shelf having at least one card whose purposes are to provide a shelf controller function and a media processor function, together with a plurality of backplane buses. The data server accesses media signals in packet form. Distributed software is distributed in the cards on the shelf, and consists of a modular software architecture having a transport layer, a media processing layer, a session control layer, and a management plane which spans across the other layers. A plurality of digital signal processors has a plurality of dynamically changeable discrete software objects so as to process packets of media data. The management plane provisions and monitors the operations of said data server, and gives alarms in keeping with predetermined criteria. There is at least one connection interface to a packet network from which media signals in media form are received.

Abstract: A system and method for maintaining privacy in transmission of a high bandwidth analog signal. A preferred system and method breaks an input signal into bands and then uses Walsh codes to overlay many signals on top of each other with a set of phase modulators to establish scrambling of the input signal. The scrambled signal is then transmitted. The received scrambled signal has the phase modulation removed and an inverse Walsh transform recovers the original bands. The recovered bands are added together to recover the original signal. The system and method use techniques that establish synchronization and phase coherency complete the process.
