Abstract: A wireless sensor system includes a sensor assembly and a sensor trigger assembly. The sensor assembly includes a housing configured to be coupled to a device actuated by a rotary actuator, at least two position sensors disposed within the housing, and a power source disposed within the housing and configured to provide power to the at least two position sensors. The housing and the at least two position sensors and the power source disposed therein are coupled to the device such that the sensor assembly is stationary. The sensor trigger assembly is configured to be coupled to and rotate with a rotatable shaft of the rotary actuator. The sensor trigger assembly includes a sensor trigger carrier configured to be coupled to the rotatable shaft and a sensor trigger connected to the sensor trigger carrier. The at least two position sensors are disposed in a first position relative to the sensor trigger to sense a change in a rotational position of the sensor trigger when the rotatable shaft rotates.

Abstract: A communications port of a network communications device maintains capability information indicating that under normal operating conditions a communications link is capable of operating in a secure mode in which communications signals of the communications link are unintelligible to an intruder having an unauthorized physical connection (e.g. tap) to the communications link. During operation, the port detects occurrence of a link event of a type that can invoke an automatic communications-mode control mechanism to change the operating of the communications link to a non-secure mode in which communications signals of the communications link are intelligible to such an intruder. An example is Ethernet auto-negotiation which can change from relatively secure 1000BaseT signaling to relatively non-secure 10/100BaseT signaling.

Abstract: The present invention provides an access control server that holds information pertaining to both network access and facility access. The access control server enforces policies based on location, type of resource, time of day, duration, or other events, and logs all successful and unsuccessful attempts to access a given resource whether it be on the network or at the facility. The access control server operates off a common list or table of attributes and policies, or separate lists or tables of attributes and policies that are arbitrated by a credential verification and policy engine. This unified access control server implements protocols that work with network and/or physical premises-based devices. The unified access control server allows events in the facility to be associated with events on the network and vice versa and direct policies that may be executed in the physical or network realm.

Abstract: Method, system and apparatus are provided for transmitting data over a network based on external, non-network oriented (external to the network) stimulus. A facility's physical security, environment monitoring/management, or production control system utilizing a frame-based/packet-based network includes a number of edge devices, an event/state change detector, a priority, security level, route specification, destination changer, a transmitter, and a number of destination devices. Edge devices generate data for the network; the event/state change detector identifies an event associated with the data; the priority, security level, route specification, destination changer changes the priority, security level, route, destination of the data, based on the detected event or state change; and the transmitter then transmits the data to an intended destination device, based on the changed priority, security level, route, and destination.
