Computing and reporting latency in priority queues
Channel traffic in Internet Protocol (IP) networks may be placed in priority queues upon receipt. Providing an efficient way for operators to use the channel may enable the operator to better make decisions for configuring the priority queues, maximizing effectiveness. For example, measuring a queue latency and making a queue latency visible to an operator may enable a better configuration of priority queues. Further, an improved latency metric may assist an operator to judge a relative effect that priority assignments have on traffic over a channel. Such techniques may be applied to an out-of-band (OOB) channel to include an assessment of parameters important for optimizing the configuration of priority queues in a downstream channel. For example, an improved latency metric for assisting an operator to judge the relative effect that priority assignments have on traffic is a parameter assessed for better use of an OOB channel. |

Semi-analog FIR filter with high impedance state
A system and method is disclosed for placing some of the elements of a FIR filter into a high impedance state in certain situations. When it is detected that the signal to an impedance element is the same as the previous value, then the driver of that impedance element is “turned off” or goes into a high impedance state, so that no current flows through that impedance element, and it no longer contributes to the filter output. Alternatively, if the impedance elements are the same between two adjacent taps of the delay line, the driver of one of those impedance elements may be turned off or go into a high impedance state. The technique may be particularly useful in differential output filters. Turning off a driver effectively removes the attached impedance element from the filter and reduces current flow and power consumption, thus extending battery life in mobile devices. |

Terminals for electrical connectors
A female terminal for an electrical connector may generally include a socket with an opening for receiving a male terminal, a first pair of contacts, a second pair of contacts, a pair of crimping members, and positioning tabs. The socket may be defined by a pair of opposing sidewalls, a top, and a bottom, at least in examples where the socket is generally rectangular. The first and second pairs of contacts may be disposed along the pair of opposing sidewalls, projecting at least partially into the socket configured to contact and exert substantially the same normal force on a male terminal that is inserted into the socket. The pair of crimping members can be utilized to secure a wire to the female terminal, and the positioning tabs may be utilized to secure the female terminal within the electrical connector. |

Electric connector
The contact state of a signal transmission medium and contact members is enabled to be maintained well by a simple configuration. Medium pressing portions of an actuator, which is subjected to a moving operation so as to electrically connect contact portions of contact members, which are in a multipolar arrangement, and a signal transmission medium (FPC, FFC, or the like) to each other, are disposed at the same positions as the contact portions of the contact members in the direction of the multipolar arrangement. The medium pressing portions of the actuator at the positions directly opposed to the contact portions of the contact members are configured to press the signal transmission medium when the actuator is moved to a working position so that the contact pressures applied from the medium pressing portions of the actuator to the signal transmission medium are reliably applied to the contact portions of the contact members without being dispersed. |
