Title: Dispositivo autoveicolare di avviamento codificato che consente la accensione successivamente all'inserimento del codice segreto sulla
Inventor: VIGOTTI GIORDANO
Filed: 1995-11-02
Abstract: La presente invenzione ha per oggetto un dispositivo autoveicolare di avviamento codificato. Di norma negli autoveicoli l'accensione dei motori è attivata mediante l'inserimento delle chiavi nello apposito dispositivo. L'invenzione integra questo sistema con un collegamento all'impianto elettrico della autoradio di bordo. Recentemente tali impianti, sono dotati di frontalini estraibili e sono protetti da un proprio codice di accesso che, nel caso l'apparecchio venga rubato, lo rende inutilizzabile.Utilizzando gli interruttori di preselezione dell'impianto autoradio, si inserisce il codice segreto di 4 cifre ottenendo la accensione dell'autoveicolo e della radio stessa, la quale successivamente si potrà spegnere. Qualora si commetta più errori successivi nell'inserimento del codice, sarà necessario l'intervento dello installatore che potrà cancellare la memoria a condizione che si dimostri la proprietà della vettura.

Patent NO-20180990-A1 (NO)
Inventor: HERRE JÜRGEN
IPC: H04S3/02
Filed: 2018-07-13
Abstract: In processing a multi-channel audio signal having at least three original channels, first and second downmix channels derived from the original channels are provided. For a selected original channel of the original channels, channel side information are calculated such that a downmix channel or a combined downmix channel including the first and second downmix channels, when weighted using the channel side information, results in an approximation of the selected original channel. The channel side information and the first and second downmix channels form output data to be transmitted to a low-level decoder, which only decodes the first and second downmix channels, or to a high-level decoder, which provides a full multi-channel audio signal based on the downmix channels and the channel side information. Since the channel side information occupy few bits only and since the decoder does not use dematrixing, an efficient and high quality multi-channel extension for stereo players and enhanced multi-channel players is acquired.

Inventor: FRIED REINHARD
IPC: C23C4/02
Filed: 1996-12-02
Abstract: A method of applying a metallic bonding layer for thermally sprayed ceramic heat insulating layers (6) on metallic components involves (a) applying a binder onto the degreased and oxide-free metallic surface of the substrate material (2); (b) applying metallic bonding powder (4) uniformly onto the binder; (c) applying solder powder (5), of smaller particle size than the bonding powder (4), uniformly onto the binder; and (d) drying the binder and heat treating to effect soldering. In an alternative method, an oxidation and corrosion resistant layer is produced on the cleaned metallic surface by gas-shielded plasma spraying prior to step (a), the bonding powder is a coarse powder having the same composition as this oxidation and corrosion resistant layer, step (c) is omitted and step (d) comprises drying the binder and then heat treating (solution annealing) to form a sintered bond between the metallic component and the oxidation and corrosion resistant layer and between the oxidation and corrosion resistant layer and the bonding powder. Also claimed are metallic bonding layers produced by the above methods.
