| 20100061425 | METHOD AND DEVICE FOR ANTI-INTERFERENCE FIGHTING IN A TELECOMMUNICATIONS SYSTEM - A method for fighting interference in a communication system is disclosed where the links are of frequency-hopping type. The signal has several frequency time slots. The system has at least one main sensor and one or more auxiliary sensors, one or more guard band are inserted between the useful bands of the frequency-hopping signal. The total area of the inserted guard bands is chosen so as to satisfy a chosen value of probability of interference interception. The signals of the inserted guard bands are selected whose level is greater than a given threshold. A set of spatial-filtering weightings are determined, for each time slot of the signal, by taking account of the correlation matrix of the noise plus jammers alone on the signals selected. The baseband signals of the assemblage of extended blocks are filtered by the set of calculated weightings of the time slot so as to generate extended blocks devoid of interference. | 03-11-2010 |

| 20120107191 | Food quality indicator - A food quality indicator includes a bio-indicator insert interposed between a gas-permeable, waterproof base and an impervious transparent cover, the base and the cover being sealed together about their peripheries to completely enclose the bio-indicator insert therebetween. The bio-indicator insert includes a porous substrate onto which a biosensor solution is applied, the biosensor solution being at least partially externally visible through the transparent cover. In use, the biosensor solution is adapted to change color within a defined color range that is dependent upon the concentration of amines detected. In this manner, the food quality indicator provides a visual indication of the state of microbial spoilage experienced by a food product in close proximity thereto. Due to its unitary, compact, durable and waterproof design, the food quality indicator can be used in a variety of potential applications and integrated into an array of different products, such as food storage containers. | 05-03-2012 |

| 20110275965 | INSTRUMENT FOR TREATING BIOLOGICAL TISSUE, METHOD FOR GENERATING SHOCK WAVE-LIKE PRESSURE WAVES IN SUCH AN INSTRUMENT - The invention relates to an instrument for treating biological tissue, including a housing, in which is disposed a ballistic device for generating extracorporeal shock wave-like pressure waves and a transfer element permanently placed on the biological tissue, said element coupling the pressure waves into the body of living creatures, wherein the transfer element couples non-focused, ballistically generated, shock wave-like pressure waves into the biological tissue, the waves generated by a striking member that is accelerated to a high final velocity of over 5 m/s by a pneumatic medium which is under an operating pressure in a pressure channel. A quick-acting valve releases the pneumatic medium, which is under working pressure, into the pressure channel, wherein a control circuit controls the duration of opening of the valve as a function of at least one or a combination of the following parameters: working pressure, impact frequency or pressure in the back-pressure chamber. | 11-10-2011 |
