Title: Spinta laterale di molla e peso centrifugo su uno dei due bracci
Inventor: SERI RANIERO
Filed: 1994-08-22
Abstract: Energia illimitata per alternatori, macchine e pompe.(Come già, Archimede, Leonardo, Pascal, e innumerevoli altri, alla ricerca di un punto di appoggio per sollevare il mondo col moto perpetuo, o seconda ruota, in grado di fornire energia illimitata da sola, abbiamo pensato all'utilizzo non della solita spinta perpendicolare al piano di incidenza, ma a quella laterale del rigonfiamento (C), che tende a portarsi sulla verticale (A-B), senza mai riuscirci, trovando sul suo cammino un braccio eccentrico di cerchio, che preme dalla parte opposta altro braccio, che tira una corda, attaccata alla circonf.za di ruota concentrica, e un gancio da questa alla corda di A-B, che scavalca la corona del cuscinetto a sfera in rotazione di binario circolare fisso, con un peso che ruotando produce centrifugazione illimitata (da centrale atomica). L'inventore SERI Raniero - CESI di Macerata - 62038 - Serravalle - Italy - propone elettrogeni, silenziosi, e RIVENDICA: 1) congegni autorotanti con trazione di molla stirata (e/o martinetto, o altro) per la spinta interna di braccio di cerchio in trazione di altro su corda e cerchio, con o senza un peso in centrifugazione).

Patent IT-TO920855-A1 (IT)
Inventor: LAZZARI GIANNI
IPC: G10L/
Filed: 1992-10-23
Abstract: A system is described for the detection and location of acoustic signals which can be used, for example, for the acquisition of voice messages or the like, in environments in which noises, echoes and reverberations are present. The system further enables an acoustic message (RS) cleared on the undesired components which are due to noises, echoes, etc. to be reconstructed. In order to perform functions of this type, the system employs an array of microphones (P0, P1, P2, P3) and is based on the Fourier antitransform calculus of only the information of phases of the normalised cross power spectrum (Y1, Y2, Y3) of pairs of signals (S0, S1, S2, S3), acquired from the microphones in the array (P0, P1, P2, P3). <IMAGE>

Title: En protokollbro mellom Bluetooth Low Energy og trådløse sensornettverk
Inventor: SVENDSEN TOBIAS BORÉN
IPC: H04W8/00
Filed: 2013-05-09
Abstract: Oppfinnelsen gjelder en løsning for trådløs ad-hoc kommunikasjon mellom BLE enheter (5) og enheter i et trådløst sensornettverk (7) som benytter protokollen ZigBee, ISA100.11a eller WirelessHART. Løsningen realiseres ved bruk av en eller flere broenheter som støtter både BLE og den anvendte protokollen i det trådløse sensornettverket (ZigBee, ISA100.11a eller WirelessHART). All standard funksjonalitet som er definert for applikasjonsnivået i den anvendte protokollen for det trådløse sensornettverket vil bli tilgjengelig for en BLE-enhet som kobler seg til broenheten. Dette blir realisert ved å innkapsle funksjonskall og returverdier i GATT karakteristikker. BLE-enheten vil ha alle funksjoner for den anvendte protokollen i det trådløse sensornettverket tilgjengelig gjennom et applikasjonsgrensesnitt. Broenheten vil utføre de faktiske funksjonskall som BLE-enheten etterspør, samt tilbakeformidle returverdier, som en fullverdig deltakende node i det trådløse sensornettverket.
