TL;DR: In this paper, each user is provided a registration key, and a long-time updated broadcast key is encrypted using the registration key and provided periodically to a user, where the user decrypts the broadcast message using the short time key.
Abstract: Method and apparatus for secure transmissions. Each user is provided a registration key. A long-time updated broadcast key is encrypted using the registration key and provided periodically to a user. A short-time updated key is encrypted using the broadcast key and provided periodically to a user. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key.

TL;DR: In this article, a method and apparatus for providing emergency notification by a wireless mobile device in response to triggering a sensor is presented, which consists of one or more sensors configured to sense an emergency event and transmit a message via a wireless link regarding the emergency event.
Abstract: A method and apparatus for providing emergency notification by a wireless mobile device in response to triggering a sensor. A detection system, which may be located within a vehicle, comprises one or more sensors configured to sense an emergency event and transmit a message via a wireless link regarding the emergency event. For example, the wireless mobile device may be programmed to call a predetermined emergency number such as E911, and transmit data including position and other information from the mobile device to the emergency number in response to the received message.

TL;DR: In this article, the authors present a CDMA system with a forward link (120) and a reverse link (130) for communicating a data packet, which is well suited for use in CDMA applications.
Abstract: In a digital communication system for communicating digital information (100), the digital communication system having a forward link (120) and a reverse link (130), a system and method for communicating a data packet. The system comprises a communicating transceiver (202), from among a number of digital transceivers (102), for sending the data packet on a random access channel (208) over the reverse link and for receiving the digital information from the forward link. The system also comprises a base station (108) for receiving the data packet on the random access channel (208) from the reverse link (130) and for sending the digital information over the forward link (120). The digital transceivers (102) share the random access channel (208). The digital transceivers (102) have a bandwidth demand. The system (100) may also include a dedicated channel (214) for communicating the data packet between the communicating transceiver (202) and the base station (108) and a processor (212) for switching from the random access channel (208) to the dedicated channel (214) when the bandwidth demand exceeds a first threshold, and for switching from the dedicated channel (214) to the random access channel (208) when the bandwidth demand drops below a second threshold. The system is well suited for use in CDMA applications.

TL;DR: A persistent positional relationship can be established among cards, represented by a one-dimensional sequence, in which newly opened cards are generally placed at the end of the sequence, although a new card that bears a relationship to an open card may, in some embodiments, be placed adjacent to the already open card as mentioned in this paper.
Abstract: In various embodiments, a card metaphor is established, in which each activity can be represented within an area of the screen referred to as a card. In various embodiments, any of several display modes are available for viewing, interacting with, manipulating, initiating, and dismissing cards. A persistent positional relationship can be established among cards, represented by a one-dimensional sequence. Newly opened cards are generally placed at the end of the sequence, although a new card that bears a relationship to an already open card may, in some embodiments, be placed adjacent to the already open card. In various embodiments, cards may be grouped, with such groups being represented as stacks of cards or by other visually distinctive means.

TL;DR: In this paper, the authors proposed a concentrated subscriber wireless remote telemetry system which uses low-cost remote communication devices operating on existing wireless communication systems in order to provide real-time reading and control of remote devices.
Abstract: A concentrated subscriber wireless remote telemetry system which uses low-cost remote communication devices operating on existing wireless communication systems in order to provide real-time reading and control of remote devices. The metering system comprises at least one powerline remote metering device which collects and forwards telemetry data to an associated wireless remote telemetry device. The wireless remote telemetry device relays the telemetry data to a central controller over existing wireless communication systems, such as cellular base stations, using existing communication standards. The wireless remote metering device transmits various messages over a shared random access channel to the central controller. The central controller transmits messages to the wireless remote metering unit over a paging channel. The wireless remote metering unit may operate in a half-duplex mode only. Furthermore, the wireless remote metering unit may provide a gateway to advanced consumer services at the remote location.
