20090086028 | CATV Digital Receiver Intermodulation Susceptibility Tester - A method and apparatus are provided for testing susceptibility of a receiver to intermodulation distortion of a digital channel, the method including selecting a first digital channel from channels in a composite signal, determining a first power measurement from the first digital channel, determining a total power measurement from other channels in the composite signal, and determining susceptibility of the first digital channel to intermodulation distortion by comparing the first power measurement and the total power measurement with intermodulation distortion characteristics of the receiver. | 04-02-2009 |
20090086804 | Automatic Gain Control Stress Measurement For Digital Carriers - The testing equipment of the present invention calculates a single “AGC stress” value, which provides an indication of the stability of the level of a digital carrier based on the change in gain required to stabilize the power of an incoming cable signal over time. Ideally the AGC stress value is rated on a scale, e.g. 1 to 10 or 0 to 5, and is fed into the DQI measurement system as a new data model. | 04-02-2009 |
20090185037 | MEASURING HUM IN A DIGITAL TV SIGNAL - The invention relates to a method for measuring Hum on a digital QAM carrier using a testing device for testing digital TV signals including a QAM demodulator therein, and to a testing device implementing the method. A micro-controller is used to sample a register associated with an AGC circuit in the QAM demodulator, and to process the collected register values to obtain one or more Hum characteristics. | 07-23-2009 |
20100014572 | TEST DEVICE AND METHOD OF DETECTING AN IMBALANCE IN A POWER LEVEL OF A CHANNEL - The present invention provides a test device and a method enabling automatic detection of an imbalance in a power level of a channel. The test device includes a tuner, a power-level measurement system, and an evaluation unit. According to the method, a test channel is selected from a plurality of channels, by means of the tuner. A power level of the test channel and a total power level of the plurality of channels are measured, by means of the power-level measurement system. A ratio of the total power level of the plurality of channels to the power level of the test channel is then evaluated, by means of the evaluation unit, to detect an imbalance in a power level of the test channel. | 01-21-2010 |
20100086015 | TEST DEVICE AND METHOD OF DETECTING AN IMBALANCE IN A POWER LEVEL OF A DIGITAL CHANNEL - The present invention provides a test device and a method enabling automatic detection of an imbalance in a power level of a digital channel. The test device includes an attenuator, a tuner, a demodulator, and an evaluation unit. According to the method, a plurality of channels are attenuated at a plurality of attenuation levels, by means of the attenuator. A digital channel is selected from the plurality of channels, by means of the tuner. A modulation error ratio (MER) of the digital channel is measured at the plurality of attenuation levels, by means of the demodulator. A variation of the MER of the digital channel with attenuation level is then evaluated, by means of the evaluation unit, to detect an imbalance in a power level of the digital channel. | 04-08-2010 |

20100016444 | Methods and Compositions for Treating Mammalian Nerve Tissue Injuries - To achieve, an in vivo repair of injured mammalian nerve tissue, an effective amount of a biomembrane fusion agent is administered to the injured nerve tissue. The application of the biomembrane fusion agent may be performed by directly contacting the agent with the nerve tissue at the site of the injury. Alternatively, the biomembrane fusion agent is delivered to the site of the injury through the blood supply after administration of the biomembrane fusion agent to the patient. The administration is preferably by parenteral administration including intravascular, intramuscular, subcutaneous, or intraperitoneal injection of an effective quantity of the biomembrane fusion agent so that an effective amount is delivered to the site of the nerve tissue injury. | 01-21-2010 |
20110052713 | REPAIRING DAMAGED NERVOUS SYSTEM TISSUE WITH NANOPARTICLES - The present application relates to reduction of acrolein-mediated cell death following neural insult. According to at least one embodiment, chitosan is utilized as a membrane fusogen to restore cell function. According to at least one other embodiment, chitosan or silica is used to create a non-toxic polymer surfaced microcolloid (PSM). PSMs were found to preferentially target the damaged nerve tissues; to restore conduction of nerve impulses; to seal/restore nerve fiber membranes; and to reduce to baseline the efflux of a large intracellular enzyme. PSMs are further used as a drug delivery vehicle for acrolein scavengers including hydralazine. | 03-03-2011 |
