摘要： A method for correcting operation of the sleep oscillator (116) of a wireless communications device (100). Sleep oscillator frequency is estimated (412) so as to compensate for estimated temperature induced errors. In estimating temperature induced errors, errors (504) in sleep oscillator frequency are treated as being temperature induced errors (522), but probable multipath errors are bounded (410, 520) to predetermined sleep clock error maxima (602) corresponding to sleep duration over which the error occurred.

摘要： A system and method of conducting wireless communications between a wireless communication device (WCD) and both a first network (e.g., IS-2000) supporting voice and data services and a second network (e.g., IS-856) supporting packet data services. The method comprises providing the WCD with a primary transceiver and a secondary receiver for conducting wireless communications in a spatial diversity for the second network traffic or broadcast; disabling the secondary receiver and spatial diversity before a paging slot or 1x system acquisition and synchronization attempts; tuning the secondary receiver to a first network carrier frequency to perform first network activities; and retuning the secondary receiver to a second network carrier frequency for spatial diversity after performing the first network activities. The first network activities may include pilot set maintenance, overhead message maintenance, page match detection, or 1x system acquisition and synchronization attempts.

摘要： A system and method of improving wireless communications between a wireless communication device and both a first network supporting voice and data services and a second network supporting packet data services. The method comprises providing the WCD with a primary transceiver and a secondary receiver for conducting wireless communications in both a simultaneous-mode and a hybrid-mode; performing simultaneous-mode-to-hybrid-mode and hybrid-mode-to-simultaneous-mode transitions based on a performance metric; and evaluating the performance metric to determine whether to perform the mode transitions. In the simultaneous-mode, the primary transceiver conducts wireless communications in the second network and the secondary receiver conducts wireless communications in the first network. In the hybrid-mode, the primary transceiver use is time multiplexed during all of the first and second networks communications combinations. When the metric measures below a threshold, the WCD reverts from one mode to another mode at paging slot wake-ups.

摘要： The present invention relates to a vent pipe de-icing system that has a first external pipe, a first internal pipe, a second external pipe and a second internal pipe. The external pipes sit above the top surface of a vent pipe, and the internal pipes sit within the vent pipe. The internal pipes are connected to a hot water tank and or pump that pumps hot water or other heated fluid through the pipes such that the heated fluid exits the external pipes and falls into the inside surface of the vent pipe. In this manner, the device can be used to continuously defrost or de-ice a vent pipe and prevent ice from forming. The device can further be controlled via a mobile application, which allows a user to control when and how much fluid is pumped within the device.

摘要： A wireless remote unit performs SPS acquisition interleaved with receiving paging information over a wireless slotted paging channel and receiving data packets over a wireless data communication system. The remote unit tunes to a pilot channel, synchronizes to an internal clock of the wireless remote unit with a pilot signal transmitted over the pilot channel; and starts a search for SPS satellites after completing synchronization with the internal clock.

摘要： A quick paging channel (QPCH) is used to receive paging indicators that indicate that a wireless communication device (WCD) has a message on a paging channel relating to, for example, an incoming call to the WCD. When the condition of the quick paging channel is too low to receive paging indicators reliably, the quick paging channel is disabled to avoid false alarms, and the slotted paging channel is used to receive paging messages without monitoring the QPCH. When the QPCH signal is strong, the probability of false alarms is lower, and the quick paging channel is enabled. By using the quick paging channel to receive paging indicators only when the QPCH signal is strong, the wireless communication device can remain in a sleep state for greater periods of time as compared with the use of a slotted paging channel. As a result, standby time may be significantly improved.
摘要翻译：快速寻呼信道（QPCH）用于接收指示无线通信设备（WCD）在寻呼信道上具有与例如对WCD的呼入有关的消息的寻呼指示符。当快速寻呼信道的条件太低而无法可靠地接收寻呼指示时，快速寻呼信道被禁止，以避免误报，而时隙寻呼信道用于接收寻呼消息而不监控QPCH。当QPCH信号强时，误报的概率较低，快速寻呼信道被使能。通过使用快速寻呼信道仅在QPCH信号强时接收寻呼指示符，与使用时隙寻呼信道相比，无线通信设备可以保持较长时间的睡眠状态。结果，可以显着提高待机时间。

摘要： A method and apparatus whereby a remote unit in a slotted mode wireless communication system may calculate accurate time throughout its entire active state. In the remote unit a “wall clock time” is calculated from a modulo 80 counter called a combiner time counter. When a remote unit enters its inactive state, counters within the remote unit, including the combined time counter, are deactivated. When the remote unit reenters its active state, the value in the combiner time counter may not be correct in relationship to slotted mode time. A controller in the remote unit forces the combiner time counted to the correct phase resulting in the combiner being within 26.66 of the correct value. The controller then determines a combiner offset to compensate for any remaining error in the combiner time counter. The control may then use the combiner time counter and the combiner offset to calculate accurate wall clock time. When convenient, such as at a slot boundary, the remote unit may reset the combiner counter to a correct value, and set combiner offset to zero.
摘要翻译：时隙模式无线通信系统中的远程单元可以在其整个活动状态下计算精确时间的方法和装置。在远程单元中，从称为组合器时间计数器的模80计数器计算“挂钟时间”。当远程单元进入非活动状态时，远程单元内的计数器（包括组合时间计数器）被禁用。当远程单元重新进入其活动状态时，组合器时间计数器中的值与时隙模式时间的关系可能不正确。远程单元中的控制器迫使组合器时间计数到正确的相位，导致组合器在正确值的26.66以内。然后，控制器确定组合器偏移量以补偿组合器时间计数器中的任何剩余误差。然后，控制可以使用组合器时间计数器和组合器偏移来计算精确的挂钟时间。当方便时，例如在时隙边界，远程单元可以将组合器计数器复位到正确的值，并将组合器偏移量设置为零。
