Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a high-performance and low-latency implementation of a wavelet-based image compression scheme. A processor may generate, in a single pass for each of a plurality of horizontal and vertical divisions of an image frame, a set of wavelet coefficients for the image frame based on a DWT. The processor may select a set of bits associated with the set of wavelet coefficients to remove based on an entropy coding process. The processor may serialize the set of wavelet coefficients, where the set of serialized wavelet coefficients do not include the set of bits. The processor may output, for a second device, a bitstream including the set of serialized wavelet coefficients.

Abstract: A side handle assembly comprises a handle configured to be gripped by a user, a rod coaxially coupled the handle and rotationally fixed to the handle, and a clamp coupled to the rod.

Abstract: Selectively automating the powering of downhole equipment during run-in-hole (RIH) operations provides a means of safely installing and monitoring downhole equipment. Selective automation comprises monitoring lowering of a pump assembly into a borehole as part of an installation process. In response to determining that the lowering of the pump assembly into the borehole has stopped, an output of power from a power source to a cable coupled to the pump assembly is allowed. A data transmission is communicated from a downhole gauge in the pump assembly to a communication device at a surface of the borehole via the cable. In response to not receiving a valid data transmission at the communication device, it is determined that the cable may be damaged, and that further cable testing should occur.

Abstract: In a satellite gateway, data is transmitted over a downstream channel at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. The downstream data is parsed to extract data packets. The data packets are then loaded into packet queues based on an identifier within such packets. The queues represent a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers that may also be based on the current signal quality at a subscriber location. The parsed data traffic is processed based on the profile of the plurality of profiles to produce processed data traffic, and transmitted from the packet queues over a downstream channel.

Abstract: A system and method for providing upstream adaptive modulation. Burst parameters associated with a range of data interval usage codes (IUCs) are defined. Each of the data IUCs has a different modulation order and forward error correction (FEC). The SNR and codeword error rate for each satellite modem in the network are monitored. The data IUCs are dynamically assigned to different satellite modems within an upstream channel based on SNR and/or codeword error rate to enable each of the satellite modems in the upstream channel to achieve maximum bandwidth efficiency during upstream data transmissions. Bandwidth requests are received from the satellite modems and granted. The grant includes the assigned data IUC. The data bursts received in the upstream channel are each processed using the parameters from the assigned IUC for each of the satellite modems sending data in the upstream channel.

Abstract: A downstream adaptive modulation system and method. The downstream adaptive modulation system comprises a wireless access termination system and one or more wireless modems. The wireless access termination system includes a plurality of queues and a parser. The parser parses data traffic onto the plurality of queues. Each queue is associated with a different coding and modulation scheme. Each of the one or more wireless modems receives data traffic from the plurality of queues based on the wireless modem's ability to demodulate and decode the signal from each of the plurality of queues. When a wireless modem experiences a change in signal strength, the present invention enables the wireless modem to adapt to data from other queues to compensate for the change in signal strength. Thus, if the signal strength improves over a period of time, the wireless modem may receive data at a higher order modulation and FEC code rate.
