Abstract: A method for uplink and downlink scheduling in a satellite long-term evolution (LTE) network includes receiving, at a satellite base station, a scheduling request from a terminal device. The method further includes transmitting an uplink and downlink grant to the terminal device with an initial allocation that supports the configured data rate. User data is sent and received from the terminal device based on this initial allocation without continually sending grants to the terminal device. The method also supports changes to the persistent allocation based on updated user traffic requirements as indicated by the terminal device.

Abstract: The present invention is related to synthesis of highly pure cationic surfactant products by eliminating or reducing impurities generation that has beset prior art. This is achieved through the N-acylation of ester of amino acid and its inorganic salts or its organic salts (e.g. amino acid or hydrochloride of amino acid or sulfate of amino acid or acetate of amino acid etc.) in non-hydrolytic or nearly non-hydrolytic reaction conditions involving mono or biphasic reaction system with fatty acid halide (C4 to C20), under moderate uniform basic condition yielding high purity N-acyl substituted amino acid ester, particularly ethyl lauroyl arginate. The present process achieves pH control through process strategy rather than the measurement and control steps. This ambient temperature process is stable through a range of temperature variation eliminating rigid low temperature control.

Abstract: A method for resource allocation in a multi-beam satellite LTE network includes determining, via a communication processor, a per sub-frame resource block (RB) threshold value on a per-beam and per-LTE carrier basis, based on a total transmission power and shared power amplifiers available to multiple beams of a space vehicle while ensuring that power amplifiers operate in a linear amplification region. The method further includes communicating the LTE per subframe RB threshold value to a downlink LTE scheduler function within the eNode-B to ensure that the count of subframe level RB allocations is less than the determined LTE per subframe RB threshold value.

Abstract: Selectively permitting or denying usage of a service available on a device is provided. Usage restrictions on usage of services available on the device are maintained, the usage restrictions including customizable restrictions on usage of the services available on the device. A usage restriction for a service indicates usage parameter(s) of the device under which the service is usable or is unusable to users of the device. Based on detecting an event associated with the device, current usage parameter(s) of the device are identified and compared to usage parameter(s) indicated by a usage restriction to determine whether the service is to be usable or unusable. Usage of the service by a user of the device is then permitted or denied based the comparison.

Abstract: System(s) and method(s) are provided for power management in an electronic display via compensation of a power source of a light-emitting-diode (LED) backlighting system. A compensation feedback loop includes a load-aware controller that receives the load condition from a dimming controller and supplies a control signal to the power source. An efficiency regulator functionally connected the backlight circuitry closes the compensation feedback loop and provides an input signal to the load-aware controller. The dimming controller implements phase-shifted pulse-modulation dimming, which based on duty cycle can establish a dimming equilibrium with two load conditions. The load aware controller includes a set of compensation blocks arranged in parallel, with a single compensation block connected to the input signal and that provides the control signal.

Abstract: A performance analysis system analyzes the performance of affiliate sites that provide links to specific items in an electronic catalog, and identifies catalog items that can be listed by such affiliate sites to improve performance. An association mining component analyzes transaction data attributable to specific categories of affiliate sites to identify items that are frequently purchased in combination by users of such sites. The detected item associations are used to evaluate, for a given affiliate site, whether significant disparities exist between the expected and actual sales quantities of specific items. The results of the analysis are incorporated into affiliate-specific performance reports, which may include specific recommendations for improving performance. The disclosed methods may also be used to analyze the performance of, and provide recommendations to, online sellers within a marketplace or auction system.

Abstract: The present invention relates to circuits and methods for detecting transistor operation in the triode region including a circuit for a transistor in a constant current source. The circuit comprises a detector having a first input, a second input, and an output. The first input of the detector is coupled to the source of the transistor and the second input of the detector is coupled to the set point terminal of the constant current source. The circuit also comprises a flag coupled to the detector output. The detector has parameters selected so that, when the voltage at the source of the transistor satisfies a reference condition, the output of the detector sets the flag. The reference condition is established relative to the voltage at the set point terminal of the constant current source and relative to the triode transition voltage of the transistor at a selected drain-source current.

The phase-shifting pulse width modulation circuit can include a counter-based programmable delay subcircuit consisting of two counter-based programmable delay blocks.

Abstract: A global demand forecast is generated for a product group in a computer system, where the product group comprises a plurality of products of a predefined genre. A historical relationship between an aggregate of product level demand forecasts and actual demand for the products in the product group, and the global demand forecast are used to adjust a critical ratio employed to generate a product level demand forecast in the computer system for a product in the product group. The critical ratio expresses a probability that the product level demand forecast will exceed an actual demand for a corresponding product.

Abstract: An IP multicast broadcast device, an IP multicast receiver device, and a method of congestion control in reliable IP multicast are described that mitigate the impact of signal blockage in radio-based IP multicast networks. In one example multicast network, the IP multicast broadcast device, and the IP multicast receiver devices may be configured to support an IGMP-based multicast protocol in which a NORM protocol, a congested packet marking protocol, e.g., such as the ECN protocol described above, and a router congestion prediction protocol, e.g., such as the RED protocol, have been implemented. In addition, the implemented NORM protocol may implement a TCP congestion control algorithm that generates adjusted transmission rates based, at least in part, on a count of ECN congestion marked packets and a count of dropped packets at a selected receiver. As a result, the generated transmission rates are not unduly affected blockage of the radio-based transmission signal.

Abstract: A performance analysis system analyzes the performance of affiliate sites that provide links to specific items in an electronic catalog, and identifies catalog items that can be listed by such affiliate web sites to improve performance. An association mining component analyzes transaction data attributable to specific categories or types of affiliate web sites to identify items that are frequently purchased in combination by users of such sites. The detected item associations are used to evaluate, for a given affiliate site, whether significant disparities exist between the expected and actual sales quantities of specific items. The results of the analysis are incorporated into affiliate-specific performance reports, which may include specific recommendations for improving performance. The disclosed methods may also be used to analyze the performance of, and provide recommendations to, online sellers within an online mall, online marketplace, or online auction system.
