Abstract: A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal/noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit.

Abstract: A method and system for logging messages in a test environment. Devices that display, output, store, or transmit log messages are instantiated as objects to log messages sent from a testing application. The testing application requests that a message be logged by a logger. The logger passes a formatted log message to a publisher. The publisher packages the log message in a trace object which is then published to each device that has requested messages of a type including the log message. The testing application need not be recompiled to cause log messages to be logged in a different manner.

Abstract: Operation commences with the cellular network infrastructure setting up a forward link and a reverse link with a cellular mobile station. The cellular network infrastructure transmits signals to the cellular mobile station on the forward link and receives signals from the cellular mobile station on the reverse link. The cellular network infrastructure monitors the quality of the reverse link. When the reverse link quality level meets a reverse link lost criteria, the cellular network infrastructure enters reverse link recovery mode of operation in which the transmit power of the forward link is increased in an attempt to recover the reverse link. During the reverse link recovery mode of operation, the cellular network infrastructure may determine that the reverse link quality meets a reverse link recovered criteria.

Abstract: A method for manufacturing a hollow parison includes forming a parison having a wail of multiple layers of polymer including a barrier layer, and open ends, each end having an end surface extending around the periphery of the respective end.

Abstract: A self coordinated machine network is established by two or more machines in proximity with each other via a wired or wireless network infrastructure. The machines are configured to establish an ad hoc network between themselves for sharing information related to their common applications. New machines that come into proximity of the network infrastructure are configured to join an existing ad hoc network. Machines that power down or are removed from proximity of the network infrastructure are eliminated from the ad hoc network. Communications between the constituent machines of the ad hoc network allow the machines to self coordinate the network and redundantly store information pertaining to the common and disparate applications of the various machines that comprise the self coordinated machine network.
