Abstract: Methods and systems are disclosed for delivery of tailored content to differentiated devices, such as desktop, mobile, and tablet devices, over a computer network. In one embodiment, a proxy cache server has a content cache for storing previously retrieved objects like web pages or multimedia files. For at least some objects, several versions are stored, each version representing an object suited for a given set of client device characteristics. A device-equivalency data structure maintained at the proxy facilitates a determination of whether such cached versions can be used to service a current request. The versions might represent, for example, modified versions created using, e.g., mobile device transcoding techniques, in response to prior requests. They may also represent a set of alternate content created by a content provider and available from an origin server. Such methods and systems may be implemented in a distributed computing networks, e.g., a content delivery network.

Abstract: Inbound call processing systems and methods for processing inbound calls to controlled-environment facility resident media and/or communications devices employ an inbound resident call server configured to host inbound calling accounts established by non-residents, receive inbound calls from the non-residents, route the inbound calls to an authenticating server, confirm that the resident device is active, and connect the inbound resident call system with the resident device if active or inform the non-resident the resident is not available if not. The inbound resident call server also connects the non-resident inbound call with the resident device if the non-resident is associated with the inbound calling account, the inbound calling account is associated with an address identifier of the resident device and the resident's personal identification number is associated with the address identifier of the resident device, all of which may be authenticated by the authenticating server.

Abstract: A process for training and optimizing a system to select video frames for optical character recognition (OCR) based on feature metrics associated with blur and sharpness. A set of image frames are subjectively labelled based on a comparison of each frame before and after binarization to determine to what degree text is recognizable in the binary image. A plurality of different sharpness feature metrics are generated based on the original frame. A classifier is then trained using the feature metrics and the subjective labels. The feature metrics are then tested for accuracy and/or correlation with subjective labelling data. The set of feature metrics may be refined based on which metrics produce the best results.

Abstract: A system and method are disclosed including an automatic sensor excitation voltage adjustment feature, a multi-range concentration feature, and a single calibration feature. The automatic sensor excitation voltage adjustment feature may include a transmitter having an associated microprocessor that provides an initial voltage to an associated sensor. The sensor may include a microprocessor, and as the voltage changes a correction signal may be relayed from the sensor microprocessor to the transmitter microprocessor. The correction signal may be used by the transmitter microprocessor to adjust the voltage applied to the sensor. The multi-range concentration sensor feature may include an amplifier associated with the sensor/microprocessor to create gain settings used to optimize sensor resolution by changing a gain value associated with the sensor. This, in turn, enables a single sensor to be used for a variety of different concentration ranges, as desired by a user.

Abstract: A method and a wearable communication system for personal face-to-face and wireless communications in high noise environments are provided. A noise cancellation device (NCD) operably coupled to a wireless coupling device (WCD) includes a speech acquisition unit, an audio signal processing unit, one or more loudspeakers, and a communication module. The NCD receives voice vibrations from user speech via a contact microphone and a second microphone and converts the voice vibrations into an audio signal. The NCD processes the audio signal to remove noise signals and enhance a speech signal contained in the audio signal. A loudspeaker emits the speech signal during face-to-face communication. The NCD transmits the speech signal to a communication device via the WCD and receives an external speech signal from the communication device during wireless communication. With the NCD, the signal intelligibility and signal-to-noise ratio can be improved, for example, from ?10 dB to 20 dB.
