Abstract: A packet communications system includes a method for maintaining quality of service by dynamically determining a maximum packet size for a communications system that transports at least one of real-time and time-sensitive data and other data in packets. Accordingly, a plurality of packets is received for transmission over a communications link. Either an encoder type or a packet size for the time-sensitive or real-time data packets is determined. A link speed for the communications link is determined. Based on the link speed and either the packet size or encoder type, a maximum packet size for any packets that do not include time-sensitive or real-time data is determined. Nominally, prior to transmission on the communications link, packets with non-real-time and non-time-sensitive data are fragmented into packets equal to or less than the maximum packet size. The maximum packet size may be dynamically reevaluated if the communications traffic or link characteristics change.

Abstract: Latch circuit and clock signal dividing circuit comprises sequentially connected latch circuits. Each latch circuit has D-type latch with latch clock input, data input and data output. A difference detector is coupled to D-type latch, and has a difference output that provides a difference signal when data at input is different than data at output. Each latch circuit has an edge triggered gate that has gate clock input, output coupled to latch clock input and gate control input coupled to difference output of difference detector. In operation, when both a transition of clock signal supplied at gate clock input is detected by edge triggered gate, and the difference signal is provided to gate control input, will edge triggered gate allow an edge of a clock signal supplied at gate clock input to determine logic values supplied to latch clock input. As a result, data at input is transferred to output.

A link adaptation parameter associated with the communication link is then selected or updated to maintain the required target error rate and the data stream is transmitted over the communication link using the selected/updated link adaptation parameter.

Abstract: There is described portable electronic devices having one or more proximity sensors with adaptive capabilities that can help reduce power consumption. The proximity sensors of the portable electronic device in accordance with the present invention may be adjusted to operate in multiple and/or different modes. These modes are environmentally and contextually driven. An adaptive sensor is dynamically adjusted based on different criteria. In particular, adjustments are based on correlations of input signals from one or more sensors of the device, data signals received from the device's processor and/or external data signals received from an external source, which provide characterization values of environmental, contextual and/or ambient light characteristics. Adjustments are made to pulse power to affect the range of the sensor, pulse frequency, filtering of noise of the sensor input signal to attenuate interference and the spectrum of a proximity detector.

Abstract: A method, a system and a base-station for automatically determining delays of data transmitted via Transmission Control Protocol (TCP) and inflating these delays in order to reduce jitter and improve TCP throughput in a communications network. A Dynamic Jitter Reduction (DJR) logic/utility operating within a communications node measures delays on a rolling basis in order to capture the delay profile. Based on the delay profile, the DJR utility determines a delay target. The DJR utility ‘inflates’/augments future/expected delays toward the delay target by performing on one or more of the following: (a) using a delay based factor in the scheduler metric for TCP applications; (b) performing fine-tuning of link adaptation schemes; (c) delaying transmission of packets at the transmit or receive buffer; and (d) delaying transmission of a received TCP ACK signal from the media access control (MAC) sub-layer to TCP layer.
