Abstract: A system may include a delta-sigma analog-to-digital converter and a digital compression circuit. The delta-sigma analog-to-digital converter may include a loop filter having a loop filter input configured to receive an input signal and generate an intermediate signal responsive to the input signal, a multi-bit quantizer configured to quantize the intermediate signal into an uncompressed digital output signal, and a feedback digital-to-analog converter having a feedback output configured to generate a feedback output signal responsive to the uncompressed digital output signal in order to combine the input signal and the feedback output signal at the loop filter input. The digital compression circuit may be configured to receive the uncompressed digital output signal and compress the uncompressed digital output signal into a compressed digital output signal having fewer quantization levels than that of the uncompressed digital output signal.

Abstract: A power cord assembly for supplying power to a drilling rig is disclosed. The assembly is assembled such that it can be easily dismantled for infield repairs and replacement of a malfunctioning component, hence it is a re-buildable unit. A series of cords containing a stack of cables that supply power to the Top Drive unit are secured in position within a hose, by several compression blocks. The compression blocks are concentric to each other about an axis. A hanging system surrounds the compression blocks and the hanging system is further surrounded by a hose. A series of king clamps are placed around the hose for firmly securing the hose in its position. The king clamps are removed when needed (for example for repair of a cable) so that all the components which make up the assembly are easily accessed by a user. The assembly is secured to a drilling rig and goes up and down in a continuous fashion during use.

Abstract: A sealing assembly is disclosed for a hinged door which is pivotable over a door threshold when closed. The sealing assembly includes a plurality of elements located within a channel positionable adjacent an edge of the door. The elements include an actuator responsive to closing of the door, the actuator having at least one connector rod extending along the channel and being movable longitudinally within the channel in response to the door closing. The or each rod is connected to at least one pivotable arm comprising rigid sections divided by flexible joints, the other end of the arm being connected to a sealing member. The or each arm is flexible such that as the or each connector rod moves along the channel, part of the arm flexes vertically thereby imparting and maintaining vertical pressure on the sealing member during use.

Abstract: A system generates one or more media streams from time-stamped packets received over a network. The packets may include audio, video, or a combination of both, sampled at a rate determined by a master media clock at a transmitter of the time-stamped packets or at some other node on the network. Timestamps in the packets may be presentation times based on values of a remote real-time clock at the transmitter that is synchronized with a local real-time clock at a receiver. The system may generate the media streams from the media stream samples and present the sampled data according to the presentation times.

Abstract: A system may route media stream samples in time-stamped packets to a media interface. The system may determine a hash value from a stream identifier that identifies a source media stream corresponding to the media stream samples. The hash value may be determined based on a combination of a first portion of the stream identifier and a second portion of the stream identifier. The system may determine whether the stream identifier identifies a subscribed media stream by looking up the hash value in a hash table. The system may route the media stream samples to a media interface if source media stream is a subscribed media stream.

Abstract: A memory management unit (MMU) may buffer media stream samples of one or more media streams, such as audio and/or video streams, in a buffer. The MMU may determine how much time a media stream sample is to be buffered by comparing a value of a real-time clock with a timestamp associated with the media stream sample. The MMU may determine a target output block in the buffer for the media stream sample based on the period of a media clock and on the amount of buffer time that the media stream sample is to be buffered. The target output block is determined relative to an output block identified by a read address. The MMU may store the media stream sample in the target output block. The MMU may increase or decrease the read address at a rate determined by the media clock.

Abstract: A system recovers a local media clock from a master media clock based on time-stamped packets received from a transmitter. The packets may include audio, video, or a combination of both, sampled at a rate determined by the master media clock at the transmitter. Timestamps in the packets may be based on values of a remote real-time counter at the transmitter that is synchronized with a local real-time counter at a receiver. The local media clock may be syntonized with the master media clock through the clock periods. The clocks may be synchronized by syntonizing the clocks and adjusting the phase of the local media clocks based on timestamps and a real-time counter.

Abstract: The present invention relates to an upright reinforcing assembly for use with a pallet racking system, and racking system incorporating the same. The support configuration consists of an upright support and attached a bracket containing two L-shaped platforms which form a pocket. The upright support configuration is placed between two frame assemblies to support the beam, which is held in the pocket created by the bracket, thereby providing additional support to the beam and preventing rotation, bowing or distortion of the beam. Such a configuration lowers the cost of pallet racking as lower capacity beams can be used, or otherwise less frame assemblies are required in the racking.

Abstract: A system for memory instantiation in a programmable logic device (PLD) includes a computing device having a processor and memory coupled with the PLD. The processor is configured to receive memory parameters including at least a data width and a data depth. The processor is also configured to determine a number and sizes of block random access memory (BRAM) primitives required for data storage based on the memory parameters and based on one or more sizes of BRAM primitives available on the programmable logic device. In one example, the processor minimizes a size of the total number of BRAMs required for instantiation on the PLD. The processor is also configured to instantiate the determined number and corresponding sizes of the BRAM primitives in logic for configuration of the programmable logic device to include a device memory within the available BRAM primitives thereof corresponding to the determined number and sizes of the BRAM primitives.
