In an embodiment, a seizure monitor provides intelligent epilepsy seizure detection, monitoring, and alerting for epilepsy patients or people with seizures. In an embodiment, the seizure monitor may be a wearable, non-intrusive, passive monitoring device that does not require any insertion or ingestion into the human body. In an embodiment, the seizure monitor may include several output options for outputting the accelerometer/gyro or other motion sensor data and video data, so that the data may be immediately validated and/or remotely viewed. The device alerts and communicated to the outside care givers via wirelessly or wired medium. The device may also support recording of accelerometer or other motion sensor data and video data, which can be reviewed later for further analysis and/or diagnosis. The device and invention is also used and applicable for other body motion disorders or detection and diagnostics.

A system is described for management of an operations area. The management system includes a central processing component with one or more central processors. An active monitoring system component is connected to the central processor. The active monitoring system includes tags and readers for individual identification of one or more tagged entities. The active monitoring system component is arrayed to create a management zone. The tags and readers are linked to the central processing component such that information from the tags and readers is received and analyzed by the central processing component. A passive monitoring system component is connected to the central processor. The passive monitoring system identifies non-tagged entities entering the management zone and additional information is communicated to the central processing component for analysis.

User names and user groups serve as the basis of a formal policy in a network. A passive monitor examines network traffic in near real time and indicates: which network traffic is flowing on the network as before; which users or user groups were logged into workstations initiating this network traffic; and which of this traffic conforms to the formal policy definition. In one embodiment of the invention, users and user groups are determined by querying Microsoft® Active Directory and Microsoft® Windows servers, to determine who is logged onto the Microsoft® network. Other sources of identity information are also possible. The identity information is then correlated with the network traffic, so that even traffic that does not bear on the Microsoft® networking scheme is still tagged with identity

Devices, systems and methods provide passive patient monitoring of such parameters as body motion, body position, respiratory rate and/or heart rate. Passive monitoring generally involves a sensor device having at least two piezoelectric sensors, provided on a surface, such as a bed, chair, operating table or the like, so that a patient may be coupled with the device by simply allowing the patient to lie, sit, lean, stand on or wear the surface. In one embodiment, multiple patients in a general care area of a hospital may be continuously monitored via multiple passive monitoring devices. If a patient fails to meet one or more predefined threshold criteria or has a negative physiological trend, the system may activate an alarm.

The present invention is directed to a system and method in which an interface (proxy) is positioned between a browser and a speech server such that the proxy, while transparent to both the browser and the speech server, collects and stores data, including utterances and other media obtained from a user, such that the media data can be retrieved in a uniform manner for subsequent manipulation, such as, for example, transcription or presentation (or preservation) of a tangible format of the media as a function of a transaction session with the user. The proxy is a passive monitoring device positioned between the functioning components of a system such that the proxy looks to the browser as a speech server and looks to the speech server as a browser.

Various user behaviors are passively monitored and recorded when a user/viewer interacts with a network video player, e.g. a web video player, while watching an online video clip. For one embodiment, a data collection agent (DCA) is loaded to the player and/or to a web page that displays the video clip. The DCA passively collects detailed viewing and behavior information without requiring any specific input or actions on the part of the user. Indications of user preferences are inferred by user actions leading up to viewing the video, while viewing the video, and just after and still related to viewing the video. The DCA periodically sends this information to a central server where it is stored in a central database and where it is used to determine preference similarities among different users. Recorded user preference information may also be used to rate a video itself.

A method and system are provided for performing elliptical-based and hybrid surveillance, performing false target detection and resolution, and performing integrity monitoring using one or more receiving and transmitting elements time synchronized to a common precision time reference, and a central workstation. Antennas for transmitting and receiving elements are located at known positions separated from one another. At a given time, one of the transmitting elements transmits an interrogation signal to one or more targets, which respond to the interrogation with a reply transmission, received by one or more receiving elements. The central workstation calculates each target's ellipse of position with respect to each receiving element, using the interrogator element time of interrogation measurement and each receiving element's time of arrival measurement for the corresponding reply transmission, and then fuses the elliptical line of positions for each receiving element to compute target positions or augment passive surveillance position. At a scheduled time, the one or more transmitting elements transmit a reference signal to the receiving elements(s). The central workstation uses each of the receiving elements time stamped signals to perform integrity monitoring.
