Abstract: A system for data aggregation and analytical scoring is described that includes a gateway operable to aggregate data received from multiple remote devices, and a device history data model storing properties for each of the multiple remote devices and storing the data received from each remote device. A scoring engine in the system acts to aggregate and analyze the data stored in the device history data model and to produce a metric based on the data. The system also includes a notification policy to conditionally notify a user based on the metric produced by the scoring engine.

Abstract: A system for providing local access by means of a local data appliance to data collected from remote monitors and sensors is described. The system includes a plurality of remote monitors and sensors, the remote monitors and sensors reporting data over a wide area communications network, and a data collection center receiving the data from the remote monitors and sensors, the data collection center operable to process the data and generate customer defined reports based on the data. A local data appliance placed in the customer's network operates to receive the data from the data collection center, and to process the customer data, generate reports based on the data and send instructions to the remote monitors and sensors. The appliance resides behind the customer's firewall but is separate from the customers network and data center equipment.

Abstract: A method for redirecting specific network traffic intended for a target device on a first data network is described. The method inserts a redirector into a first network in front of a target device and intercepting a transmission from the target device. The method then configures the network characteristics of the redirector to use the network addresses of the target device. Once configured the redirector inspects the network traffic on the first network to identify specific services, and sends the network traffic associated with the specific service to a destination device on a second network.

Abstract: A system for sending updates to a large number of remote units is described. The system includes a plurality of remote units, each remote unit comprising one or more sensors and a communications transceiver. A control center is in communication with the remote units and includes an update database reflecting the update status of each of the plurality of remote units. The control center establishes contact with each of the plurality of remote units and sends an update when communication has been established. The update database is periodically updated to reflect the completion of the update for each mobile unit based on a completion message from each of the remote units that has successfully installed the update.

Abstract: A system for tracking mobile assets is described. The system includes a plurality of mobile asset tracking devices, where each of the tracking devices has a short range radio transmitter used to transmit identifying information to other nearby tracking devices. A subset of the plurality of mobile asset tracking devices also include location determination modules and wide area network communications transmitters, this subset of mobile asset tracking devices is operable to collect the identifying information of the nearby tracking devices without the wide area network communication transmitter and to transmit the location and identifying information of the nearby tracking devices to a monitoring center to track the plurality of mobile asset tracking devices.

Abstract: MOSFET structures are frequently used to establish the charge level in the first potential well of a CCD in accordance with an external voltage. When employed conventionally there exists a finite amount of charge under the MOSFET gate at the instant of turnoff. An indeterminate amount of this charge flows into the first potential well thereby giving rise to an uncertainty in the amount of charge in the well. Use of the invention disclosed eliminates this source of uncertainty.

Abstract: It is frequently desirable to establish the level of charge in the first potential well of a CCD in accordance with an external electrical signal. Thermal noise associated with the output resistance of the external source gives rise to uncertainty in this charge level. The use of a floating diffused region as an intermediate receptacle for the charge introduced permits a substantial reduction in the magnitude of this uncertainty.
