A method for detecting a face in a mid-shot digital image of a person comprises capturing first and second mid-shot digital images of nominally the same scene using different capture settings such that the foreground is differently differentiated from the background in each image, and comparing the first and second images to determine the foreground region of the images. A portion of the foreground region likely to correspond to a face is estimated based upon the geometry of the foreground region.

Monitoring system for automatic charging apparatus for vehicle
InactiveUS7053792B2Centralized managementLong calculation timeAcutation objectsTicket-issuing apparatusDummy dataMonitoring system
When a monitor apparatus judges that a vehicle has stopped at a predetermined position (step 705), the monitor apparatus transmits pseudo position information of the vehicle (dummy data) to an automatic charging apparatus (step 725). The automatic charging apparatus calculates a charge amount on the basis of the dummy data, and transmits the result of the calculation to the monitor apparatus. The monitor apparatus receives the result (step 735) and judges on the basis of the result whether the automatic charging apparatus is in an anomalous state (step 740). Since the above-described successive operations are performed only when the vehicle stays, the status of another automatic charging apparatus not monitored is not misidentified as the status of an automatic charging apparatus to be monitored.

A method for estimating the performance of a croupier at a roulette table. For each period of time the croupier is working at a roulette table the total amount bet by individual players participating in multiple spins of a roulette game is determined. The game that has a chipper machine and an intelligent table terminal. The method involves interfacing the chipper sorting machine with the table terminal, allocating a chip to a patron at the terminal, counting the number of color chips sorted by the chipper machine per color, and associating the number of color chips sorted by the machine per color with the patron. The total amount bet by that patron is then determined by mathematically linking the chip value of the color chip of the patron with the number of chips of the individual color sorted by the chipper machine in the time period in which the color chip is associated with that patron.

Reducing interference in a GSM communication system
InactiveUS7187736B2Reduces co-channel and adjacent channel interferenceSacrificing interference cancellation performanceMultiple-port networksDelay line applicationsFinite impulse responseCommunications system
A method for reducing interference in a desired signal in a GSM communication system uses a finite-impulse-response filter for alternate linear equalization. The method includes a first step (300) of inputting a burst of data of a received waveform including interference from a channel of the communication system. A next step (302) includes training the finite-impulse-response filter with a set of symbols of specific quadrature phase, known a priori, in the burst of data of the received waveform. For example known real only and imaginary only symbols are alternatively selected from a midamble of the data burst. A next step (304) includes operating on the received waveform with the finite-impulse-response filter to alternately linearly equalize the burst of data to provide an estimate of the desired signal.

Method, equipment and recording device for suppressing pulsed interference in analogue audio and/or video signals
InactiveUS6654471B1High click densityLess complexTelevision system detailsAnalogue recording/reproducingPeak valueEngineering
Clicks in voice and music signals are removed by detecting and interpolating the click. The use of a permanently set threshold value above the peak value of the audio signal is known for detecting the clicks, and interpolation carried out on the basis of the sample values before and after a click is known for filling them in. Disadvantages of these methods are, on the one hand, that many clicks do not have a larger amplitude than the peak signal and therefore remain undetected, and, on the other hand, interpolation is a highly complex procedure and is limited to a maximum click density. The invention provides for an error signal (en) to be determined by adaptive filtering (AF). A sample value is designated as distorted in the input signal (xn) if the absolute instantaneous value in the error signal (en) exceeds a dynamically adapted threshold value. The output signal of the adaptive filtering (yn) is used as a substitute value for the sample value designated as distorted, specifically both in the case of the signal which is output and in the input values of the adaptive filtering.

Fast arbitration scheme for a bus
A distributed arbitration scheme includes arbiters with each agent. The arbiters receive request signals indicating which agents are arbitrating for the bus. Additionally, the agent currently using the bus broadcasts an agent identifier assigned to that agent. The arbiters receive the agent identifier and use the agent identifier as an indication of the winner of the preceding arbitration. Accordingly, the arbiters determine if the corresponding agent wins the arbitration, but may not attempt to calculate which other agent wins the arbitration. In one embodiment, the arbiter maintains a priority state indicative of which of the other agents are higher priority than the corresponding agent and which of the other agents are lower priority. In one implementation, the bus may be a split transaction bus and thus each requesting agent may include an address arbiter and each responding agent may include a data arbiter.
