20130093444 | Remote Sensing of PD-Side Voltage in 4-Pair PoE Applications for Estimating Cable Resistance - Provided is a system and associated method for detecting a resistance of a cable. An example method may comprise applying power to a first end of a first and a second conductive pair of the cable, measuring a first voltage across the first end of the first and second conductive pairs of the cable, applying a current source across the first end of a third and a fourth conductive pair of the cable, measuring a second voltage across the current source, and determining a resistance of the cable using the measured first and second voltages. This method may be carried out in a physical arrangement where a second end of the first, second, third and fourth conductive pairs of the cable are connected to a first, a second, a third and a fourth input terminal of a powered device, respectively. | 04-18-2013 |
20140111180 | METHOD AND APPARATUS FOR CURRENT SENSING IN POWER OVER ETHERNET (PoE) SYSTEMS - Systems and methods are provided for power control. In some implementations, a power control system includes a first transistor having a drain coupled to a first conductor (e.g., first pair of wires of an Ethernet cable), a second transistor having a drain coupled to a second conductor (e.g., second pair of wires of the Ethernet cable), a current sensor coupled to sources of the first and second transistors, and a current management circuit. The current management circuit may detect drain voltages of the first transistor and the second transistor, and adjust gate voltages of the first transistor and the second transistor to keep the drain voltages of the first transistor and the second transistor approximately equal. The current management circuit may detect a current through the current sensor, and adjust the gate voltages of the first transistor and the second transistor to limit the detected current to a current limit. | 04-24-2014 |
20140136874 | LOW LATENCY DISCOVERY FOR POWER OVER ETHERNET - Embodiments of the present disclosure provide systems and methods for reducing discovery time in a power over Ethernet (PoE) system where the nature of a load is known or can be safely assumed. By using prior knowledge of the nature of the load, the discovery procedure can be simplified. A power source device (PSE) controller measures a port voltage to determine if an open circuit exists or if a short circuit exists. If neither an open circuit or a short circuit exists, the system can be safely powered up. | 05-15-2014 |

20150254049 | Dynamic Playout of Audible Punctuation in Connection with Playout of Playlist Content - Disclosed are methods and systems for dynamically playing audible punctuation in connection with playout of content defined by a playlist. A client receives a playlist defining a sequence of media content items to be played out by the client, the playlist indicating attribute data for each media content item of the sequence. For each of at least one of the media content items of the playlist, the client determines based on the attribute data and perhaps based on user preference data an audible punctuation to play out in connection with playout of that media content item, and the client retrieves and plays out the audible punctuation in connection with playout of that media content item. | 09-10-2015 |
20150254050 | Generating a Playlist Based on a Data Generation Attribute - An example method involves determining an attribute associated with an audible version of a news story, wherein the attribute indicates a manner in which data representing the audible version of the news story was generated; using the determined attribute associated with the audible version of the news story as a basis to generate a playlist of a news program that includes the audible version of the news story; and transmitting the generated playlist to a client device. | 09-10-2015 |
20150254051 | USE OF AN ANTICIPATED TRAVEL DURATION AS A BASIS TO GENERATE A PLAYLIST - An example system may include a communication interface; a processor; and a non-transitory computer-readable medium having stored thereon program instructions that when executed by the processor cause the server to perform of a set of functions. The set of functions may include determining an anticipated travel duration of a user of a client device, using the anticipated travel duration of the user as a basis to generate a playlist of a personalized news program for the user, and transmitting data representing the generated playlist to the client device. | 09-10-2015 |
20150255055 | Personalized News Program - An example method involves (i) accessing data representing a text-based version of a news story; (ii) using a text-to-speech system to convert the accessed data representing the text-based version of the news story into data representing an audible version of the news story; (iii) determining a set of attributes associated with a user of a client device; (iv) using the determined set of attributes associated with the user as a basis to generate a playlist for a personalized news program, wherein the playlist includes a reference to the converted data representing the audible version of the news story; and (v) transmitting the generated playlist to the client device. | 09-10-2015 |
20150255056 | Real Time Popularity Based Audible Content Aquisition - A personalized news service provides personalized news programs for its users by generating personalized combinations of audible versions of news stories derived from text-based versions of the news stories. The audible versions may be generated from the text-based version by a text-to-speech system, or may by recording a person reading aloud the text-based version. To acquire recordings, the personalized news service can make a determination that a particular news story has a threshold extent of popularity. The news service can then transmit a request to a remote recording station for a recording of a verbal reading of the particular news story. The news service can then receive the requested recording from the remote recording station. | 09-10-2015 |
