  • Patent number: 10742523
    Abstract: Some tests can be implemented as services. A network provider can deploy (“push”) a test to a container resident on one or more devices of the network, either at installation, periodically, or when a problem is reported. When a customer reports an issue, services running on one or more devices of the customer's installation can cause the containerized tests to be run. For example, the central office of the network provider can initiate a request to run the test through the internet (or other connection) by the container. In some implementations, there is an overlap of the service based test set with traditional technician initiated test sets forming a hybrid testing architecture.

  • Patent number: 10405234
    Abstract: Systems and methods provide load balancing on time division multiple access (TDMA) inroute channels of a satellite network. A bandwidth allocation manager or module can employ smart admission techniques to admit new terminals based upon the available bandwidth capacities of TDMA inroute channels including committed information rate (CIR) bandwidth requirements of already admitted terminals and current and CIR bandwidth requirements of the new terminals. Attempts are made to fully load a first TDMA inroute channel before providing admission to a second TDMA inroute channel. Additionally, an already admitted terminal requesting increased bandwidth or one or more other already admitted terminals may be reassigned to one or more alternative TDMA inroute channels to accommodate the requested increase in bandwidth.

  • Patent number: 10359827
    Abstract: A number of ones in the difference between a current pulse code modulated (PCM) audio sample and an immediately preceding audio sample is compared to a number of ones in the current audio sample to determine which has the fewer number of ones. The audio source sends either the difference or the current audio sample, whichever has fewer ones. By reducing the number of ones sent over a non-return to zero inverted (NRZI) audio bus from an audio source to an audio sink, the number of transitions is reduced, which reduces the power consumed relative to a transmission that does not use this process.

  • Patent number: 9841940
    Abstract: Power reduction through clock management techniques are disclosed. In one aspect, the clock management is applied to a clock signal on a SOUNDWIRE™ communication bus. In particular, a control system associated with a master device on the communication bus may evaluate frequency requirements of audio streams on the communication bus and select a lowest possible clock frequency that meets the frequency requirements. Lower clock frequencies result in fewer clock transitions and result in a net power saving relative to higher clock frequencies. In the event of a clock frequency change, the master device communicates the clock frequency that will be used prospectively to slave devices on the communication bus, and all devices transition to the new frequency at the same frame boundary. In addition to the power savings, exemplary aspects of the present disclosure do not impact an active audio stream.

  • Patent number: 9384065
    Abstract: A system and method of managing the storage of data is described where a plurality of requesting entities can be permitted access to a shared data resource. When a modification to the data is needed, the request may be executed as an atomic operation. To do this the memory region is temporarily locked until the atomic operation is completed so that other operations related to the data are deferred until the atomic operation has completed. The lock is secured by reference to a data array or register of fixed length where the address of the locked data region is represented by a bit, the position of which is determined by computing a hash value of the address modulo the length of the lock register.

  • Patent number: 9306696
    Abstract: A wireless network is provided that includes a base station and subscriber stations that communicate with the base station using radio frequency (RF) time division duplex (TDD) signaling. The base station may establish medium access control (MAC) connections with each station. The base station monitors communications with the stations and, in accordance, assigns stations or MAC connections to modulation groups. The base station transmits signals on MAC connections or to stations in a modulation group in adjacent TDD slots within a TDD frame. The base station may receive access requests from the stations, evaluate traffic requirements for the stations, and determine a longest downlink portion for the stations. The base station then allocates downlink and uplink portions of a TDD frame according to the length of the longest downlink portion.

  • Patent number: 9295010
    Abstract: This disclosure provides several mechanisms for adapting transmit power spectral density (PSD). A communications device may adapt the power spectrum utilized at the transmitter based, at least in part, on the channel conditions or PSD constraints associated with the communications medium between the transmitter and a receiver device. Additionally, the transmit PSD may be adapted based, at least in part, on a total power capability associated with a transmitter. Power is allocated to improve throughput and utilization of the communications channel. A transmission profile may be selected based, at least in part, on the notch depth. The transmission profile may be associated with symbol timing parameters. The communications device may maintain a plurality of selectable pulse shapes that are optimized for different notch depths.

  • Patent number: 9258233
    Abstract: A method for adjusting a set of primary rate limits for transmission rates of data flows having a certain priority in a transmitter is provided. A mean value is determined of a duty cycle of the certain priority at the port as obtainable from the transmission or flow control, wherein the data flows having different priorities including said certain priority are transmitted by a port of the transmitter, transmissions for rate-limited data flows having the certain priority are limited by secondary rate limits (r1?, r2?, . . . rn?) per data flow, and transmissions for all data flows having the certain priority are controlled by a transmission or flow control per priority. The secondary rate limits (r1?, r2?, . . . rn?) are obtained by adjusting the primary rate limits for the transmission rates of the data flows having the certain priority based on the determined mean value of the duty cycle.

  • Patent number: 9217781
    Abstract: A multi-cell battery pack in an electric vehicle is monitored by multiple sensing modules. A primary controller is coupled to a first plurality of cells to measure a predetermined parameter of each cell. The primary controller determines a sampling moment recurring at a fixed frequency for sampling the predetermined parameter of each of the first plurality of cells. The primary controller generates a sync pulse at each sample moment. A secondary controller is coupled to a second plurality of cells to measure the predetermined parameter of each cell. The secondary controller receives the sync pulse to start a pulse generator operating at a frequency which is a predetermined multiple of the primary controller fixed frequency. The secondary controller counts pulses generated by the pulse generator and schedules a synchronized secondary sampling moment according to a predetermined pulse count.

  • Patent number: 9147193
    Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.
