    摘要: A system and method for measuring a lead edge and/or a trail edge media curl utilizing a dual cross beam sensor. The dual cross beam sensor includes one or more pairs of emitters (e.g., a pair to two pairs of emitters) and one or more detectors positioned sequentially in a media path so that a media passes via dual cross beams. Timing data with respect to the media can be measured as the media crosses via the dual cross beam sensor from a leading edge and/or trailing edge. A true instantaneous media speed and a curl height (i.e., media tip height or media curvature) can be simultaneously calculated from the timing data associated with the lead edge/trail edge with respect to each single cross beams of the dual cross beam sensor. An average curl height can be then calculated to enhance the accuracy of the media curl measurement.

    摘要: In certain communication systems, such as TD-HSDPA communications, channel quality index (CQI) reporting is based on a predetermined configuration, such as a mobile device (UE) reporting a CQI for a most recently received data transmission. This configuration may lead to errors if a UE reports a CQI for a certain data transmission but the base station (node B) believes the CQI corresponds to a different data transmission, such as a later transmission the UE never received due to an error processing control channel information. Offered is an indicator to accompany CQI reports. The indicator indicates to the node B which communication resource corresponds to the CQI report.

    摘要: An apparatus includes a photoreceptor belt, a fixed transfer roller positioned on the inside of the photoreceptor belt, and a movable transfer roller positioned on the outside of the photoreceptor belt. The fixed transfer roller and the movable transfer roller are positioned to form a nip, and the photoreceptor belt and a web of print media are positioned in the nip. Also, a support roller and a compensation roller contact the web of print media. The support roller is positioned between the compensation roller and the nip. A physical link is connected to the support roller and the compensation roller. The physical link moves the support roller and the compensation roller so as to keep a constant tension on the web of print media.

    摘要: In TDD-LTE wireless systems, an additional fourth preamble for the random access channel, called short RACH, may be used. If short RACH signaling is to be used, the random access preamble is transmitted in the uplink pilot time slot (UpPTS) field in the special subframe. The location of the uplink pilot time slot (UpPTS) is next to a downlink subframe. Therefore, interference from neighbor base stations may interfere with the short RACH preamble within the uplink pilot time slot. The interference to the short RACH will prevent the eNodeB from detecting the short RACH preamble and thus prevent the UE from accessing the network. An interference level on an Uplink Pilot Time Slot (UpPTS) may be measured and when the interference level exceeds a threshold value a User Equipment (UE) is instructed to disable short Random Access Channel (RACH) signaling. The UE may then be instructed to enable normal RACH. When the interference level falls below the threshold value the UE is instructed to resume short RACH signaling
