摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

摘要： A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

摘要： Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

摘要： An ammonia adsorption product is described which may be used for fresh caught fish and bait. The product may comprise functionalized tectosilicate compound and a buffer. High concentrations of ammonia produced by fish waste can be lethal, even though oxygen availability is rich enough to keep fish breathing. The product is a user-friendly, sustainable, affordable product which is able to extend the life of the fish by safely removing ammonia by an ion-exchange mechanism. This product can convert toxic ammonia into ammonium and uptake ammonium by releasing sodium ions in the water.

摘要： Maintaining communication of a wireless device and using a plurality of wireless communication technologies. A first paging message schedule may be determined for maintaining communication between the wireless device and a first base station associated with a first wireless communication technology. Similarly, a second paging message schedule may be determined for maintaining communication between the wireless device and a second base station associated with a second wireless technology. Additionally, a scheduling conflict may be determined between the first paging message schedule and the second paging message schedule. Accordingly, communication with the first base station may be switched to a third base station using the first wireless technology in response to determining that there is a scheduling conflict.

摘要： In one illustrative example, a technique in a mobile communication device which is operative in a wireless communication network for Push-To-Talk (PTT) communications involves receiving, at the mobile communication device, presence information associated with at least one other mobile communication device, the presence information including at least one of a current availability indication or capability indication; and buffering a PTT communication prior to its transmission from the mobile communication device based on the presence information. The current availability or capability indication may be an automatic answering indication or a media capability indication, as examples.
