  • Patent number: 7319811
    Abstract: A moving image processing apparatus can perform a zoom process for each frame image of moving image data in an digital zoom section. An image quality determining section determines an image quality of a frame image obtained through the zoom process in reproduction, when this zoom process is performed, and passes quality information representing its determined result to an MPEG CODEC. The MPEG CODEC encodes the moving image data processed in the digital zoom section and a noise reduction section, and stores the image data, and the quality information associated with each frame in a storage medium. In this manner, when the reproduction object data is processed to have some effect on the quality in reproduction, the data can be provided with the information regarding the quality in reproduction.

  • Patent number: 7319819
    Abstract: The invention is the novel use of dispersion compensation in a long haul wavelength division multiplexed high capacity optical transport system which has very many channels packed extremely closely together, in order to greatly reduce the deleterious effects of four-wave mixing. Four-wave mixing is an exchange of energy between nominally independent channels, arising from the fundamental fiber non-linearity, which has the effect of degrading transmission quality. Conventional systems make use of fiber dispersion compensating modules to overcome the effects of fiber dispersion. In such systems, it has been discovered that the exact distribution of fiber dispersion along the optical link (the ‘dispersion map’) strongly influences the degree of four-wave mixing, and hence the degradation in transmission quality.

Such messages are referred to as “electronic car-mail” or “C-mail” messages as each message has a destination or origination address which includes an identifier, e.g., a vehicle identification number (VIN), identifying the automobile. The messages may be delivered to the automobile from a remote server through a communications network, e.g., the Internet. One such message may contain a recall notice to the automobile. Another message may contain just-in-time map information for navigation, depending on the current location of the automobile. Yet another message may contain advertising information concerning selected entities, e.g., restaurants, gas stations, department stores, etc., also depending on the current location of the automobile. The messages transmitted from the automobile to the remote server may contain, e.g.

  • Patent number: 7319849
    Abstract: A system for tuning a radio-frequency signal includes a first input path, a second input path, a common reference generator, a selector, a mixer, and a filter. The first input path and the second input path propagate a first single-ended input signal and a second single-ended input signal, respectively, to the selector. The selector converts the first single-ended input signal and the second single-ended input signal into a first differential input signal and a second differential input signal, respectively, using a reference signal generated by the common reference generator. The selector selectively couples one of the first and the second input path to an input of the mixer. The mixer downconverts a selected on of the differential input signals received from the selector. The filter attenuates a portion of the downconverted input signal outside a passband associated with the filter.

  • Patent number: 7319850
    Abstract: In a low noise block downconverter converting a right-hand (or horizontally) polarized wave signal and a left-hand (or vertically) polarized wave signal to intermediate frequency signals, one of two filters for removal of interference waves from the intermediate frequency signals on the right-hand (or horizontally) polarized wave side and on the left-hand (or vertically) polarized wave side is formed of a plurality of stages of parallel resonant trap circuits having capacitors and inductors connected in parallel, respectively, which exhibit attenuation characteristic that is wideband and steep and allows great attenuation in the reject band. Thus, it is possible to provide a low noise block downconverter employing an LPF that achieves attenuation characteristic being wideband and steep and allowing great attenuation in the reject band with the least possible number of inductor components that would otherwise increase the cost.

  • Patent number: 7319852
    Abstract: An apparatus for coarse compensation of a direct current (DC) offset in a direct to baseband receiver architecture utilizes a serial analog to digital converter (ADC), such as a Delta-Sigma converter, to convert the received signal to digital form. The output of the ADC is sampled for a predetermined number of samples and a counter coupled to the ADC is incremented each time the sample generated by the ADC is a logic one. The counter is not incremented if the sample from the ADC is a logic zero. After the predetermined number of samples is obtained, the counter value is indicative of the DC offset in the received signal. The counter value may be converted by a code converter to a correction value for easy operation of a digital to analog converter (DAC). If the number of samples from the ADC is a power of two, the code converted may be readily implemented by simply inverting the most significant bit (MSB) from the counter to thereby generate a twos complement version of the counter value.

  • Patent number: 7319854
    Abstract: During a system reconfiguration, a selected column or column of wireless units, such as associated with airplane seats, are powered up. The first unit in the column detects a ground and begins a wireless identification process with an access point which allows the system to determine a corresponding physical location for each node's logical address. The first unit then closes a switch, which connects the ground to the next unit. As the next unit detects the ground on the line, such as a token line, the second unit communicates with the AP. This process continues sequentially down the column until the last unit is assigned a physical location/address. The next column of units can then be powered up and identified.
