  • Patent number: 8348543
    Abstract: A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars having raised bosses are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable. An external device is attached to a pair of cuffs in the form of C-shaped cylindrical rings each with a circular inner surface. A gap in the ring interrupts the inner surface. The width of the gap is greater than the diameter of the bosses so that the cuffs may be slid onto the collars when the gaps are aligned with the bosses. The bosses are circumferentially offset when the cable is in its normal operating state to lock the cuff and the external device to the collars. The cuffs and the external device can be installed on or removed from the cable by twisting the cable to align the bosses and sliding the cuffs onto or off of the collars. When installed, the cuffs ride on the races to allow the cable to rotate inside the cuffs.

  • Patent number: 8346224
    Abstract: An improved system and method for rating subscribers based on wireless subscriber specific credentials. A wireless network operator, or a content/application provider assigns to a subscriber a unique username. For purposes of providing rating or feedback information, the assigned username acts uniquely to identify the subscriber, whose actual identity therefore remains anonymous. The subscriber uses his or her mobile phone to access a mobile telephony network. Evaluators may offer feedback or ratings of the subscriber using the internet.

  • Patent number: 8346313
    Abstract: Techniques for dynamically selecting warm-up time for a wireless device operating in the idle mode are described. At each active interval, conditions affecting warm-up of the wireless device at a next active interval are determined. The conditions may pertain to channel conditions, operating conditions, and/or hardware configuration. A warm-up time is selected based on the determined conditions. A wake-up time for the next active interval is determined based on the selected warm-up time. The wireless device then goes to sleep until the wake-up time. In one scheme, the strongest pilot acquired in each active interval is identified, and its pilot strength is averaged to obtain an average pilot strength. The average pilot strength is compared against at least one threshold, and one of at least two possible time durations is selected for the warm-up time based on the comparison result.

  • Patent number: 8345646
    Abstract: The access terminal is configured to wirelessly send to a data system a request that the data system assign an access terminal identifier (ATI) to the access terminal. The access terminal delays transmission of the request until after a user of the access terminal has employed the access terminal to request a packet data service from the data system. In some instances, the data system is an Evolution, Data Only (EV-DO) system and the access terminal identifier (ATI) is a Unicast Access Terminal Identifier (UATI) generated by the Evolution, Data Only (EV-DO) system.

  • Patent number: 8344542
    Abstract: Disclosed is a power assembly for supplying electrical power to 4-20 mA 2-wire field devices, including HART-enabled, short run Profibus PA, and Foundation Fieldbus protocols. A preferred embodiment of the power assembly is designed to simplify the testing, troubleshooting, and configuration of HART 2-wire field devices. The disclosed device is compatible with hand-held or PC-based configuration software, and utilizes the available power from the USB port of a laptop, or any other compatible source of low-voltage DC. An internal circuit converts the low voltage DC to 24-volt DC to provide 2-wire power for the field devices. The power supply includes the necessary network communication load and/or resistance and may provide a quick modem/network interface and/or milliamp meter connection. All the necessary connections to the 2-wire field device are made with a single pair of quick-disconnect fittings.

  • Patent number: 8342313
    Abstract: An accumulation-and-release conveyor using a roller belt with rollers arranged to rotate in the direction of belt travel. The rollers extend through the thickness of the belt. A movable stop is positioned along the carryway just downstream of a bearing surface that is movable into and out of contact with the rollers. When the bearing surface is out of contact with the rollers, they are freely rotatable; when the bearing surface contacts the rollers, they roll on the bearing surface to propel articles in the direction of belt travel. The stop is selectively moved between a blocking position preventing articles from passing and accumulating them with low back line pressure on the freely rotatable rollers and a release position allowing articles to pass to the accumulation zone where they are propelled forward and separated from each other by the rotation of the rollers rolling on the bearing surface.
