Passive correlation is done via monitoring of the gripping pressure of the operator's hand(s) on a handgrip containing pressure transducers. Correlation with Hori stage 2 is a preliminary indicator of the onset of operator fatigue. Active correlation is done via contingent Psychomotor Vigilance Tests administered upon the preliminary indication, with operator stimulus from a vibratory element in the handgrip and operator response being a rapid increase in gripping pressure. Correlation of the frequency of contingent PVT requests with Hori stage 3 is a critical indicator of the onset of operator fatigue. Upon detection of the onset of fatigue, an alarm is signaled to the operator and other personnel. | 03-12-2009 |

20130091197 | MOBILE DEVICE AS A LOCAL SERVER - Architecture that embeds a server (a local server) inside a mobile device operating system (OS) close to the data (but under the OS services) such that the server has access to native capabilities, and offers an Internet-like frontend with which a browser or application can communicate. The local server appears as a web server, and small programs can be pushed into the local server from the browser or a remote server such that the local server can be made to perform work more effectively. Local and remote events can be triggered such as launching a browser (or other application(s)), initiating remote server calls, triggering battery save mode, locking the phone, etc. The local server can run a script execution environment such as node.js, an event driven I/O model where callbacks are invoked to handle emergent conditions (e.g., explicit requests, state changes, etc.). | 04-11-2013 |
20130097440 | EVENT SERVICE FOR LOCAL CLIENT APPLICATIONS THROUGH LOCAL SERVER - In server/client architectures, the server application and client applications are often developed in different languages and execute in different environments specialized for the different contexts of each application (e.g., low-level, performant, platform-specialized, and stateless instructions on the server, and high-level, flexible, platform-agnostic, and stateful languages on the client) and are often executed on different devices. Convergence of these environments (e.g., server-side JavaScript using Node.js) enables the provision of a server that services client applications executing on the same device. The local server may monitor local events occurring on the device, and may execute one or more server scripts associated with particular local events on behalf of local clients subscribing to the local event (e.g., via a subscription model). These techniques may enable development of local event services in the same language and environment as client applications, and the use of server-side code in the provision of local event service. | 04-18-2013 |
