Abstract: A dust screen for an inspection hatch disposed in the roof or a side wall of a dry bulk storage unit for use during pneumatic loading of aggregate material from a pneumatic trailer via air pressure ducted into the bulk storage unit. The dust screen includes an elastic cord in a hem surrounding an open end of the screen to secure the dust screen to the inspection hatch. An alternative embodiment may include a binding strap having a ratchet buckle to supplement the elastic cord. As the dust screen extends upward in the presence of said air pressure, the dust is allowed to settle into the storage unit. No separate container to contain the dust is required, and no separate structure is required to support the dust screen during operation. The dust screen is light weight, portable and reusable, and low in cost.

Abstract: Methods, systems, and computer program products for dynamically monitoring, processing, and managing alerts are described herein. In an embodiment, the method operates by receiving messages that are either alerts or responses to existing alerts. The messages are parsed to determine if whether they are alerts or responses to alerts. Actions including updating alert states and storing alert data are executed, and then the method sends notifications regarding the alert messages and responses to a collaboration list of registered subscribers that dynamically expands over time based upon alert escalations. The method then determines whether additional messages have been received; and performs actions associated with these additional messages until there are no remaining alerts or alert responses to process. The method stores updated alert and response data in a repository so that the alerts and responses can be monitored and managed.

Abstract: Methods, systems, and computer program products for monitoring, aggregating, and correlating business events in real time and acting on the results with near zero latency, wherein each event is processed in the first order relative to the event density, are described herein. In an embodiment, the method operates by receiving historical values comprising keys and data fields at an analytic model. Rules associated with actions are applied to the historical values. Actions including updating data are executed pursuant to the rules, and then the method determines whether additional rules are to be applied; and performs actions associated with these additional rules until there are no remaining rules to apply. The method stores updated data in a database.

Abstract: A power management scheme for a wireless communications device substantially implemented on a single CMOS integrated circuit is described. The present invention provides a method and apparatus for generating first and second clock signals for a wireless communication device, with the first and second clock signals corresponding first and second power levels, depending on the operating mode of the wireless communication unit. In the first operating state, the transceiver in the RF analog module is operational and the clock generator provides a first clock signal having the high-speed, high-accuracy characteristics necessary to maintain efficient operation of the transceiver. In a second operating state, the transceiver in the RF analog module is turned off. In this second operational state, the clock generator provides a second clock signal having a frequency and quality sufficient to maintain efficient operation of the digital modules in the wireless communication device.

Abstract: A method and apparatus for providing multiple clock signals for a communication device, with the clock signals being generated to correspond to the operating mode of various core modules of the communication device. A clock generator is operable to generate a plurality of clock signals having performance characteristics corresponding to the operating mode of individual cores in the system. A clock management logic circuit is operable to receive a plurality of request signals from the core modules and to cause the clock generator to generate appropriate clock signals based on the requests and other information relating to the operating mode of the core modules.

Abstract: A power management scheme for a wireless communications device processor substantially implemented on a single CMOS integrated circuit is described. By incorporating controls for sleep and wake-up mode transitions in the processor's control logic, improved power savings with reduced latency is provided, obviating the need for hardware-focused solutions with elaborate signaling mechanisms. A fully integrated power management with staged wake-up operations controlled by the MAC solution consumes less power than the conventional wireless LAN solutions in standby mode.
