| 20100119020 | Blanking Techniques in Receivers - An aspect of the present invention detects the presence of interference by examining an input signal received on an input path, and blanks the receiver if interference is detected. Information contained in the input signal may be recovered otherwise. In an embodiment, the duty cycle of a jamming signal is determined by examining the input signal, and a threshold strength having a positive correlation with the duty cycle is determined. If the strength of the jamming signal during the on-interval (start and end of the interference in each cycle) is greater than the threshold strength, then only the receiver is blanked. Otherwise, no blanking is performed, and only the gain of an amplifier in the path from the input path to a baseband processor is reduced. According to another aspect, one or more cycles of the interference is used to detect the start of interference and the receiver is blanked when interference is present. | 05-13-2010 |
| 20110026651 | AUTOMATIC GAIN CONTROL IN A RECEIVER - Automatic gain control in a receiver. A method for controlling operating range of an analog-to-digital converter (ADC) by an automatic gain control circuit includes estimating a peak-to-average ratio corresponding to an analog signal from digital samples of the analog signal. The method includes determining a peak value corresponding to the analog signal based on the peak-to-average ratio. Further, the method includes maintaining magnitude of the analog signal at an input of the ADC and gain of the receiver based on the peak value. | 02-03-2011 |
| 20110051639 | DYNAMIC LOW POWER RADIO MODES - A receiver in a packet based communication system includes a programmable block and a detection block that detects at least one of an operating condition of the receiver and a protocol condition of the communication system. Further, the receiver includes a control circuit coupled to the programmable block that controls the programmable block to transition to a set of radio modes according to at least one of the operating condition and the protocol condition. | 03-03-2011 |
| 20110111714 | METHOD AND SYSTEM FOR FALSE FREQUENCY LOCK FREE AUTONOMOUS SCAN IN A RECEIVER - Method and system for false lock free autonomous scan in a receiver is disclosed. The method includes identifying a presence of a desired signal to avoid false frequency lock in a Frequency Modulation receiver. The method includes receiving a signal. The method further includes identifying the desired signal, if a first energy is above a first threshold. The method also includes identifying the desired signal, if an Intermediate Frequency count is below a second threshold. The method includes identifying the desired signal, if a second energy of the signal is above a third threshold. The method includes identifying the desired signal, if an absolute difference between a first Received Signal Strength Indication (RSSI) value and a second RSSI value of the signal is below a fourth threshold. The method includes determining a third energy. The method includes identifying the desired signal, if the third energy is below a fifth threshold. | 05-12-2011 |

| 20100264973 | ECONOMY PRECISION PULSE GENERATOR - A system includes an input device, an output device, a mechanical chassis, a printed circuit board, and a semiconductor device. The semiconductor device includes a mechanical package, and a semiconductor die. The semiconductor die includes a semiconductor layer, a plurality of metal layers, a clock distribution network that distributes a clock signal within the die, and an economy precision pulse generating circuit. The economy precision pulse generating circuit includes a pre-charge circuit, a gate-to-the-partial-jam-latch-keeper circuit, a partial-jam-latch-keeper circuit, and a pull-down-against-the-up-keeper circuit. A source clock signal is derived from the clock signal. The source clock signal is provided to a first input of a logical AND circuit, the pre-charge circuit, and the gate-to-the-partial-jam-latch-keeper circuit. A common storage node is connected to a second input of the logical AND circuit. The logical AND circuit outputs an output pulse. The output pulse is fed back to the pull-down-against-the-up-keeper circuit. | 10-21-2010 |

| 20090299179 | Method For Detecting Cardiac Transplant Rejection - A method for detecting cardiac rejection in heart transplant patients is disclosed. The wall mechanics, such as wall shear, stress, and strain, of a heart ventricle of the transplant patient are measured. A property of the native vasculature is also measured. The measured property may include the wall mechanics or thickness of the native blood vessel. The wall mechanics measurements of the ventricle and the measured property of the native vasculature are compared, and the comparison is outputted. The outputted comparison is matched either to similarly-obtained comparisons from heart transplant patients undergoing early cardiac rejection of the transplanted heart or to similarly-obtained comparisons from heart transplant patients with normally-functioning hearts. | 12-03-2009 |
| 20100022887 | Method for imaging intracavitary blood flow patterns - A method for identifying blood flow patterns based on contrast-enhanced ultrasound imaging and, in particular, echocardiography. The method includes indicating a blood flow type in the cavity through which imaged blood is flowing by correlating the identified blood flow pattern with a selected pattern. Further, a report indicative of a condition of the cavity can be generated based on the indicated blood flow type. | 01-28-2010 |
| 20100130866 | Method for determining flow and flow volume through a vessel - A method for measuring and displaying flow and flow volume in the vessel of a subject. The method includes acquiring ultrasound data from a subject and producing a color Doppler m-mode image depicting the vessel. A 3D representation of the color Doppler m-mode image is then generated to enable an operator to identify the blood vessel and window the ultrasound data accordingly to a selected range of heart beats. Blood vessel walls are automatically identified from the windowed ultrasound data and blood flow through the vessel lumen is measured using pulsed Doppler ultrasound, which is gated to substantially exclude data from outside the lumen. Volume flow through the vessel is determined by multiplying the measured blood flow with a calculated cross-sectional area of the vessel and an image indicative of the volume is then generated and displayed. | 05-27-2010 |
