Patent HK-1144966-A1 (HK)
Title: Optical fiber coupling part comprising grin lenses
Inventor: MATSUMURA HIROYOSHI
IPC: G02B6/42
Filed: 2010-12-07
Abstract: An optical fiber coupling part capable of reducing coupling loss while maintaining a large operating distance, and having a good module assembling property. An optical fiber 4 has numerical aperture NAf, A first GRIN lens 1 has numerical aperture NA1. A second GRIN lens 2 has numerical aperture NA2. The second GRIN lens 2 has a first end fusion-spliced with one end of the optical fiber 4. The first GRIN lens 1 is fusion-spliced at one end with the other end of the second GRIN lens 2. The other end of the first GRIN lens 1 is unattached. The numerical aperture NA1 of the first GRIN lens 1 is larger than numerical aperture NA2 of the second GRIN lens 2. Thereby, the lights emitted from a light-emitting source 3 with a numerical aperture NAs can efficiently enter the optical fiber, and loss of the lights can thereby be reduced. In this case, the formula expressed by NAf ¤ NA2 < NAs ¤ NA1 is desirable. All lights emitted from the light-emitting source with a numerical aperture NAs can enter the GRIN lens, and the loss of the light can thereby be reduced.
Patent HK-1013747-A1 (HK)
Title: Method and system for audio scrambling and descrambling
Inventor: QUAN RONALD
IPC: H04K1/04
Filed: 1998-12-23
Abstract: Audio signals are descrambled by double sideband modulating the scrambled audio signal with a modulation carrier having a carrier frequency slightly above the highest audio signal present in the scrambled audio. This produces a double sideband signal that is passed through a low pass filter which in turn is modulated by a second carrier frequency lower than the first carrier signal by equal to the offset spectrum of the original scrambled signal. The first low pass filter nulls out any residual carrier from the first modulator that results form the intermodulation of the two modulation frequencies that would be audible at its descrambler output. The modulators used are low noise switch type modulators that improve the signal to noise ratio in the descrambled signal over the previously used linear modulators. The use of switch type modulators provides a lower cost device with improved performance. A companion scrambling device uses similar techniques to provide improved performance at a lower cost.

Title: An insulating medium
Inventor: ROCHEFORT MALCOLM
IPC: C04B26/00
Filed: 2007-10-17
Abstract: An insulating medium comprises a plurality of hollow microbodies which are gas impermeable and have a low aspect ratio.  The hollow bodies may be microspheres which are formed from a glass material.  The microbodies are bonded in a resin such as a phelonic, polyurethane or polyisocyanurate material.  The hollow microbodies have an internal void pressure of less than 0.1 bar a.  Panels formed from such an insulating medium are described.  Such panels have superior insulating properties and can be punctured by a nail or cut to size without adversely affecting its insulating properties.
Patent IE-20140303-A1 (IE)
Title: Fenestration system for radio frequency attenuation
Inventor: DARAGH NAUGHTON
IPC: H01R4/00
Filed: 2014-11-28
Abstract: The present invention relates to a fenestration system that acts in a manner to attenuate electromagnetic radiation across a spectrum of 500 MHz to 6 GHz. Attenuation of a minimum of 28 dB is achieved using a combination of a conductive metallic oxide coating, a conductive tape, a conductive gasket, a frame assembly and an earth bonding strap connected to an earthing point. The advantage of the present invention is that radio frequency attenuation can be achieved without sacrificing light transmission and is therefore suitable as a structural element in areas where a high level of security is required in tandem with aesthetic appeal. The fenestration system provides security and protection from unwarranted sources of electromagnetic energy and serves a duality of function. In the first instances, radio frequencies across a broad spectrum from GPRS to Wi-Fi and beyond can be attenuated in a localised manner from being received. In the second instance, the transmission of the afore mentioned spectrum can be attenuated to such an effect as to render transmission impossible. Such a duality of function provides commercial appeal to end-users such as prison authorities, military applications and government/private commercial entities tasked with the protection of electronic data from unwarranted interception.

Title: Deflutasy
Inventor: MAINO PIETRO
Filed: 1995-11-14
Abstract: Questo rivoluzionario sistema di travaso liquidi per taniche consente, con un minimo di sforzo, di ottenere un risultato massimo e preciso, evitando che chi voglia eseguire il travaso di un fluido da una tanica con sistema DEFLUTASY ad un altro recipiente, ad es. una bottiglia, si affatichi inutilmente a sollevare il bidone tenendolo sospeso durante il travaso ed evitando, a causa di tale scomodissima posizione, l'antipatico versamento di liquido sul pavimento. Tutto questo grazie alla semplice applicazione al tappo: di un comunissimo rubinetto stretto al tappo da una guarnizione larga quanto la circonferenza interna del tappo stesso e di un dado che stringa tale guarnizione al tappo ed al rubinetto inserito, quest'ultimo, nel tappo, attraverso un foro praticato sulla superficie liscia di quello (tappo). Entrata la filettatura del rubinetto nel tappo, stretto il dado e chiuso il tappo, anche capovolgendo il bidone il liquido non sgocciola grazie alla larga guarnizione che ha una duplice funzione: stringere il rubinetto e stringere il tappo. Posteriormente al bidone c'è un foro di presa d'aria e un tappetto.

Title: "circuito tampone e relativo procedimento di funzionamento"
Inventor: CONNELL LAWRENCE E
IPC: H03F1/32
Filed: 1994-11-04
Abstract: Un circuito ed un procedimento forniscono un circuito tampone o buffer a bassa distorsione mediante l'impiego di uno stadio partitore resistivo (18, 20) ed uno stadio di guadagno (12), il cui guadagno è uguale all'inverso del rapporto di attenuazione del partitore resistivo per fornire un guadagno unitario. Una molteplicità di ingressi (14, 42, 44,... 46) al circuito tampone sono resi possibili per mezzo di una rete di commutazione di ingresso (30, 38). L'errore di guadagno introdotto dalla resistenza della rete di commutazione (30, 38) viene eliminato inserendo una rete equivalente (60) in un percorso di retroazione dello stadio di guadagno. La preferita topologia del circuito è perfettamente conveniente per applicazioni a bassa tensione e fornisce una uscita a bassa distorsione. Sono anche previsti mezzi per ridurre il consumo di energia elettrica (68, 70) e per minimizzare i transienti indesiderabili (72).
