Abstract: A system for tracking personnel and equipment in hazardous environments in pre or post-accident situations includes an intrinsically safe tracking tag and an intrinsically safe reader system. The intrinsically safe tracking tag transmits identification and status information to the intrinsically safe reader system, which includes a plurality of intrinsically safe antennas and a hub cable driver. In one embodiment, antennas are located at known positions in the hazardous environment and connected via a redundant, wired-mesh topology. The wired-mesh topology also allows more flexible antenna placement than line-of-sight wireless-mesh systems. The hub cable driver provides intrinsically safe power to and communication with the antennas using communication cables, receives data signals from the antennas, and transmits the data signals to a server. The server stores the data signals in a storage device and is connected to a workstation. The workstation retrieves the stored data to track persons or equipment.

Abstract: A system and method for detecting a proximity of a person to a machine includes a first transmitter unit carried by the person, a plurality of receiver units located on the machine at know locations, and a processing unit including data defining a first boundary around the machine. The first transmitter unit transmits a magnetic proximity signal having a predetermined signal strength and a predetermined signal frequency. Each of the plurality of receiver units is for determining a received signal strength of the received magnetic proximity signal. The processing unit: determines a location of the first transmitter unit relative to the machine based on the received signal strength of the magnetic proximity signal and the known location of the plurality of receiver units; and outputs a proximity warning signal if the location of the transmitter relative to the machine is within the first boundary around the machine.

Abstract: A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers. When used in conjunction with FEC encoding, the methods include delivering portions of an encoding of each source block from potentially different servers.

Abstract: A sequence of symbol operations (a “schedule representation”) within a data storage device, wherein the operations are those used to process encoding or decoding operations of a forward error correction code (an “FEC code”) upon an arbitrary block of data of a given size (where size can be measured in numbers of symbols). The method is such that the schedule representation can be used to direct the processing of these operations upon a block of data in a way that is computationally efficient. Preferably, the same method can be applied to represent schedules derived from multiple different algorithms for the encoding or decoding of a code or for multiple different codes.

Abstract: Techniques are disclosed for representing a user quality of experience (QoE) experienced by users of a streaming media service using a single QoE metric. The single QoE metric may be determined based on a set of empirical characteristics relating to the streaming video service such as startup latency, video quality, and the likelihood of interruptions in streaming playback. The empirical characteristics may be weighted according to how much one factor influences user quality of experience, relative to the others. Representing the QoE as a single metric may allow a streaming media service provider to improve key business measures such as subscriber retention and engagement.
