20120063591 | METHOD AND APPARATUS FOR CONTROLLING ECHO IN THE CODED DOMAIN - A method and corresponding apparatus for coded-domain acoustic echo control is presented. An echo control problem is considered as that of perceptually matching an echo signal to a reference signal. A perceptual similarity function that is based on the coded spectral parameters produced by the speech codec is defined. Since codecs introduce a significant degree of non-linearity into the echo signal, the similarity function is designed to be robust against such effects. The similarity function is incorporated into a coded-domain echo control system that also includes spectrally-matched noise injection for replacing echo frames with comfort noise. Using actual echoes recorded over a commercial mobile network, it is shown herein that the similarity function is robust against both codec non-linearities and additive noise.

The names of the people identified in the image are used in naming the image files and in naming the path to the image files. | 2012-03-15 |
20120063651 | REAL-TIME PLAYER TRACKING - Some implementations of the invention provide methods, devices and systems for acquiring patron data in real time. A plurality of networked cameras may be used to acquire information regarding casino patrons. The cameras may include “smart cameras” having an integrated machine vision system. The real-time information may be used to populate one or more databases of a player loyalty program. Patron information may also be used to determine trends associated with patron demographics, with levels of a player loyalty program, etc. Some implementations of the invention involve monitoring patron event data and determining when predetermined events of interest occur. When a defined event occurs, patron data relating to the associated patron may be monitored, analyzed and used to populate one or more player loyalty databases. In some implementations, patron data acquired prior to the time of the defined event may also be analyzed and used. | 2012-03-15 |
20120063652 | Method and apparatus for performing color-based reaction testing of biological materials - Color-based reaction testing of biological materials may be performed by capturing, in an uncalibrated environment, a digital image of an exposed test strip, together with an adjacently-located reference color chart or on-strip color chart. The image data specifically representing the individual test pads on the test strip, as well as the reference color blocks on the reference chart, are then located within the captured image, and compared to identify any color matches between the test pads and the corresponding sequences of reference color block. Based on this comparison operation, a set of test results can be generated which effectively identifies which of the reference chart's color blocks most closely matches the color of the corresponding dipstick's test pads. The generated test results may then be provided to the user in a printed or displayed form. Alternatively, the test results may simply be stored for later retrieval. | 2012-03-15 |
