20110057501 | PIPELINE PIG BRUSH AND BRUSH ASSEMBLY - A brush useful in pipeline pigs, for example, in magnetic flux leakage tools or cleaning tools, a method of making the brush and pipeline pig comprising the brush. The brush has a metal bristle holder and a plurality of bristles, the ends of which are held in the bristle holder by glue, swaging or a combination of glue and swaging. The glue may be an anaerobic glue. The brush and method of making avoid the use of heat to secure the bristles to the bristle holder, avoid the use of solder or weld metal, and are less labor intensive than soldering or welding. | 03-10-2011 |

20080205380 | SWITCHBOARD FOR MULTIPLE DATA RATE COMMUNICATION SYSTEM - A switchboard device and methods of operation of same are disclosed. Embodiments of the invention may provide a flexible means of interconnecting wideband and narrowband communications interfaces, where wideband communications interfaces may transfer low-band data and high-band data, and narrowband communication interfaces may transfer low-band data. Low-band data may be combined and sent to a narrowband communications interface or a wideband communications interface. High-band data may be combined and sent to a wideband communications interface. The low-band data may represent audio signals below a predetermined frequency, while the high-band data may represent audio signals above the predetermined frequency. The predetermined frequency may be, for example, approximately 4 kHz. The spectral mask of the low-band data may meet the spectral mask of G.712. Methods of operating embodiments of the present invention are included. An additional aspect of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing. | 08-28-2008 |
20080291940 | Switchboard For Dual-Rate Single-Band Communication System - A switchboard device and methods of operation of same are disclosed. Embodiments of the invention may provide a flexible means of interconnecting wideband and narrowband communications interfaces, where wideband communications interfaces may transfer wideband data sampled at a higher sampling rate, and narrowband communication interfaces may transfer narrowband data sampled at a lower sampling rate. Data streams sampled at different sampling rates can be combined and the sampling rate of the result adjusted as needed by the destination interface. Methods of operating embodiments of the present invention are included. An additional aspect of the present invention may include machine-readable storage having stored thereon a computer program having a plurality of code sections executable by a machine for causing the machine to perform the foregoing. | 11-27-2008 |
20100104049 | DUAL-RATE SINGLE BAND COMMUNICATION SYSTEM - A system, method, and apparatus for a multiple data rate communication system is presented herein. The communication system receives data samples that are either sampled at a narrowband rate or a wideband rate and provides various functions and services, such as echo cancellation, DTMF detection and generation, and call discrimination. For wideband signals, a down-sampled signal is provided for each of the foregoing function and service. The output of the function or services is then recombined with the wideband signal. | 04-29-2010 |

20100325302 | GENERIC ON-CHIP HOMING AND RESIDENT, REAL-TIME BIT EXACT TESTS - Details of media encoding and decoding devices which support generic homing sequences, and methods for operating such devices are disclosed. The use of generic homing sequences may permit an embodiment of the disclosed invention to support real-time, bit-exact testing of existing and future media encoding and decoding devices. An embodiment of the present invention may permit the initialization of encoding and decoding algorithms to a known state, enabling bit-exact testing of a large group of devices using these algorithms, including those whose specifications do not support such functionality. This capability may permit the full-speed, bit-exact, testing, of both locally and remotely situated media encoders and decoders. | 12-23-2010 |
20110135038 | MULTIPLE DATA RATE COMMUNICATION SYSTEM - Seamless wideband support is afforded by utilizing split-band data streams. For wideband signals, the 8 kHz bandwidth is divided into a low band, with approximately 0-4 kHz bandwidth, and a high band, with approximately 4-8 kHz bandwidth. Narrowband functions and services operate on the low band, while wideband functions and services operate on both low and high bands. | 06-09-2011 |
