A cluster storage system comprises a plurality of nodes that access a shared storage, each node having two or more failover partner nodes. A primary node produces write logs for received write requests and produces parity data for the write logs (storing the parity data to local non-volatile storage). By storing parity data rather than actual write logs, the non-volatile storage space within the cluster for storing write logs is reduced. Prior to failure of the primary node, the primary node also sub-divides the write logs into two or more sub-sets and distributes the sub-sets to the two or more partner nodes for storage at non-volatile storage devices. Thus, if the primary node fails, its write logs are already distributed among the partner nodes so each partner node may perform the allotted write logs on the storage, thus improving the response time to the primary node failure.

In a peer-to-peer network system, a local node communicates with a remote node on which detailed information about content objects resides and optionally, the content objects reside. The local node uses caching, message request resizing and predictive message requesting to speed response time to user requests and internal control node requests.

A network caching system for streamed applications provides for the caching of streamed applications within a computer network that are accessible by client systems within the network. Clients request streamed application file pages from other client systems, proxy servers, and application servers as each streamed application file is stored in a cache and used. Streamed application file page requests are broadcast to other clients using a multicast packet. Proxy servers are provided in the network that store a select set of streamed application file pages and respond to client requests by sending a response packet containing the requested streamed application file page if the streamed application file page is stored on the proxy server. Streamed application servers store all of the streamed application file pages. Clients try to send requests to streamed application servers as a last resort. Clients can concurrently send requests to other clients, to a proxy server, and to a streamed application server. Clients measure the response time to the client's requests placing a positive weighting on the more responsive request path and sending subsequent requests to the more positively weighted request path first.

Security systems typically communicate with alarm monitoring centers using a telephone connection. Security systems will check in with the alarm monitoring center with a diagnostic signal at a predetermined interval—typically once per day. When a security system is connected to a Voice-over-IP service (using Broadband Internet), rather than a standard telephone line, the opportunity exists to poll in real-time the status of the connection, and alert the owner (or alert the alarm monitoring center) that the customer's connection has been broken. The present invention offers a system and technique for monitoring a security system connected using a Voice-over-IP connection, in real time, and alerting the owner of the security system, or the alarm-monitoring center, when the connection is broken. This alert can be used, for example, to issue a telephone call to the police, informing them of the breach of line integrity and possible compromise of the premise.

In order to provide a combination weighing apparatus having an automatic filter adjusting capability which is effective to secure a weighing accuracy and also to adjust a filter characteristic of a digital filter having a short response time, the filter characteristic is automatically adjusted, based on a result of comparison of respective vibration components U of filtered weight signals FW1 to FWn with a permissible level US of the vibration components, so that the respective vibration components U of the filtered weight signals FW1 to FWn can attain a value approximating to the permissible level US, but not exceeding the permissible level US. In this way, by damping the vibration components U down to a value within the permissible level US, the weighing accuracy can be secured and, on the other hand, by damping the vibration components U down to a value approximating to the permissible level US, the filter characteristic can be obtained quickly in a short time.

A method of detecting the state of an operator of a vehicle utilizes a low-cost operator state detection system having no more than one camera located preferably in the vehicle and directed toward a driver. A processor of the detection system processes preferably three points of the facial feature of the driver to calculate head pose and thus determine driver state (i.e. distracted, drowsy, etc.). The head pose is generally a three dimensional vector that includes the two angular components of yaw and pitch, but preferably not roll. Preferably, an output signal of the processor is sent to a counter measure system to alert the driver and / or accentuate vehicle safety response.

Security systems typically communicate with alarm monitoring centers using a telephone connection. The present invention offers a system and technique for monitoring a security system connected using a Voice-over-IP connection, in real time, and alerting the owner of the security system, or the alarm-monitoring center, when the connection is broken. This alert can be used, for example, to issue a telephone call to the police, informing them of the breach of line integrity and possible compromise of the premise. In addition, the present invention allows for one-way or two-way voice communication between the alarm panel and an alarm operator and / or a 3rd party. Such voice communication helps the alarm operator and / or 3rd party to determine whether an alarm is a real alarm or a possible false alarm.

The invention relates generally to a computer system and method for integrating insurance policy underwriting. In one aspect, it integrates an older legacy insurance policy generating system to on-line rating systems where users access the system through browsers. The computer system to perform the process of dynamically rating includes generating an input XML file of risk information that is sent to a web service and calculated in a calculation engine. The processed data is retrieved by the web service and transmitted as an XML file to a user interface that parses the rating information and displays the data.

Disclosed is a system for copying data sets from a first storage device to a second storage device. The first storage device is managed by a first controller and the second storage device is managed by a second controller. The first controller receives a command to copy a plurality of data sets from the first storage device to the second storage device. First and second data structures are generated to include fields corresponding to the data sets. The fields initially indicate that the data sets have not been copied. For the data sets subject to the copy command, the first controller transfers a copy of the data set to the second controller. The second controller stores the copy of the data set received from the first controller in the second storage device. The field in the first data structure corresponding to the data set copied to the second storage device is then modified to indicate that the data set was copied to the second storage device. The field in the second data structure corresponding to the data set the second controller stores in the second storage device is also modified to indicate that the data set was stored in the second storage device.

An approach is provided for supporting retrieval of web content over a meshed communication network. A first server receives a request from a browser application for the content resident in the web server. The first server includes a downstream proxy configured to modify the request to include information specifying support of a parse and pre-fetch service within an optional header field of the request as to permit handling of the modified request by the web server in absence of an upstream proxy that is communicating with the web server. A second server is configured as the upstream proxy to intercept the modified request and pre-fetch the content from the web server. The second server forwards the pre-fetched content over the communication network to the first server. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

A geo-fence is defined and established automatically based on a current location of an asset along with some range or distance, avoiding the need for a user to manually specify a location by drawing a perimeter, specifying a point location, or by any other means. Once established, the geo-fence can be activated so as to notify the owner of the asset and / or some other entity of movement of the asset beyond the boundary specified by the geo-fence. In one embodiment, the geo-fence can be automatically activated upon certain conditions, or can be manually activated, or any combination thereof.

An approach is provided for supporting retrieval of a web page over a data network from a web site is disclosed. A downstream proxy communicating with a host executing a browser receives a request message from a browser to retrieve the web page. An upstream proxy parses the web page to determine an object embedded in the web page, wherein a promise list is generated specifying the embedded object that is to be pre-fetched according to a criterion. The promise list is transmitted to the downstream proxy, wherein the upstream proxy pre-fetches the embedded object from the web site. The upstream proxy determines whether to forward one of the pre-fetched embedded object to the downstream proxy based on a comparison of cookies associated with one of the pre-fetched objects supplied, respectively, by the browser and the web site. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

Light sources are affixed at appropriate positions in a multilevel structure or in an obstructed environment. The light sources generate modulated light signals, such as controlled light-emitting diodes, which identify the positions of the light sources by their three-dimensional global positioning coordinates and / or equivalent representation that specifies their in situ locations in the environment. Mobile communication devices, upon receiving the light signals, can derive spatial positioning information and transmit such information to a remote location, such as an emergency response system.
