Title: Process for managing a symmetric key in a communication network and devices for the implementation of this process
Inventor: ANDREAUX JEAN-PIERRE
IPC: H04N21/2347
Filed: 2002-04-09
Abstract: Process for managing a symmetric key in a communication network and devices for the implementation of this process The communication network comprises a device of a first type (1) furnished with a source of data to be broadcast over the network and at least one device of a second type (2) intended to receive the said data. The symmetric key management process comprises the following steps: - the source device (1) determines a first symmetric key (Kc) and transmits it securely (E1{PUB2}(Kc)) to at least one receiver device (2); - a receiver device (2) receives the first symmetric key (Kc), encrypts it (E2) with the aid of a second symmetric key (Kn), known to the receiver devices (2) of the network and transmits it to the source device; - the source device (1) recovers the encryption (E2{Kn}(Kc)) of the first symmetric key (Kc) and stores it.      Before transmitting the data (CW) to at least one reception device (2), the source device (1) encrypts (E3) these data with the aid of the first symmetric key (Kc), then it transmits these encrypted data (E3{Kc}(CW)), accompanied by the first encrypted symmetric key (E2{Kn}(Kc)), to at least one receiver device (2). The receiver device (2) decrypts the first symmetric key (Kc) with the aid of the second key (Kn) which it possesses, then it decrypts the encrypted data with the aid of the first symmetric key thus recovered.      The invention also pertains to devices for implementing the process.

Title: Piezo-electric content use monitoring system
Inventor: PETERSEN MICHAEL
IPC: G01M99/00
Filed: 2002-04-24
Abstract: A content use monitoring system is provided for monitoring use of blister packaged contents. The monitoring device comprises an integrated circuit, battery and piezo-electric foil or other transducer that can be attached to a existing blister package, in physical contact with their backing, via adhesive. When a content is expelled from a blister through the backing, the piezo-electric foil or other transducer is deformed, generating an electrical signal. The integrated circuit monitors the piezo-electric foil circuit for such signals, analyzes them, and if they meet the programmed specifications, the time and other characteristics of the event are recorded in the integrated circuit's memory. The content use data can later be downloaded for analysis, education or clinical purposes via either a remote or contact reader.

Title: Dual closure nozzle
Inventor: BONZER ROBERT L
IPC: B05B1/30
Filed: 2002-11-04
Abstract: A dual closure nozzle for use with a hose carrying a liquid under pressure. The dual closure nozzle is made up of an inner delivery conduit attached to an end cap and threaded within an outer sleeve. The nozzle is configured to have two different stop positions and to be adjustable between these two step positions and a variety of open positions. When a liquid is forced through the nozzle, the flow of the liquid can then be adjusted from a first stop position, where no liquid passes out of the nozzle, through a variety of open position spray patterns to a second stop position. This configuration thus provides a nozzle that can be closed by turning the outer sleeve portion of the nozzle in either of two directions.
