摘要:
A method for link quality control in a wireless communications network includes determining whether an indicator of link imbalance exists among a plurality of base stations associated with a mobile unit, and implementing a control action to help prevent at least one of fading or signal cutoff between the mobile unit and at least one of the base stations, if the indicator indicates that link imbalance exists.
摘要:
A system is implemented on a wireless network for adjusting a forward link power control parameter based on forward link feedback. A wireless unit is in communication with several base stations during soft handoff, and provides feedback relating to forward link quality, e.g., forward link pilot signal strength or traffic channel frame error rate. The feedback is compared to a comparison or reference point (such as target frame error rate, or a maximum pilot signal strength in the active set) chosen for gauging the quality or nature of the feedback for power control purposes. Based on this comparison, a power control parameter of one or more of the base stations may be adjusted upwards or downward. The power control parameter may be a forward link reference transmit power level “Pref” used to control base station power transmission levels in the presence of power control bit errors.
摘要:
A cooler for fluids uses multiple internal channels to increase the time a hot fluid is contained in the cooler, thus increasing cooling efficiency, and allowing the length of the cooler to be shorter than an equivalent cooler with fewer passes. The cooler uses external and internal heat-exchanging fins to increase surface area for contact with both the fluid and the external environment. The cooler is designed around a cylindrical vessel, equipped with a set of internal baffles, forming the multiple channels. End caps, one of which contains inlet and outlet ports, are welded to the cooling vessel, increasing ability to contain pressure. The small channel size and fluid flow-path holes cut through the baffles prevent air bubbles, which would reduce cooling efficiency. Coolers with four channels are provided for higher-pressure applications and coolers with six channels are provided for lower-pressure applications. Some coolers have an air flow assembly with a fan, to direct more cooling air around the cooler vessel. An airflow assembly with a fan controlled by a thermostat on the cooler is also disclosed.
