Abstract: Systems and techniques are generally described for audio signal processing for motion detection. In some examples, a first energy level of a first audio signal detected by a first microphone is determined over a first period of time. In some further examples, a first change in the first energy level from a first energy level value to a second energy level value is determined during the first period of time. In some other examples, a determination is made that the first change in the first energy level exceeds a threshold change value associated with the first period of time. In at least some other examples, a bias of an audio amplifier of the first device is adjusted.

Abstract: Methods of operating a cellular radio are provided in which a first power supply signal is transmitted from a power supply to a wireless power unit at least in part over a power cable. A second power supply signal is wirelessly transmitted from the wireless power unit to the cellular radio to power the cellular radio. Data is transmitted from a baseband unit that is associated with the cellular radio to a wireless transceiver at least in part over a data cable. This data is wirelessly transmitted from the wireless transceiver to the cellular radio. The data is then transmitted through an antenna that is coupled to the cellular radio.

Abstract: Aspects of the present disclosure are directed to rule based switchable polarization techniques. In one aspect, a device may receive one or more RF signals. A packet error rate associated with the received one or more RF signals may be determined. A polarization switching circuit may determine if the measured PER is greater than a predetermined threshold PER. In response to the determination that the PER is greater than the predetermined threshold PER, the polarization switching circuit may change a polarization of the device.

Abstract: A system and method for defining a boundary within a wireless coverage area using a physical access control system (PACS) and limiting access to the wireless network to devices located within the boundary area is provided. The system includes a PACS for controlling access to a secured area defined by the boundary to authorized personnel and a wireless network generating system for generating a wireless network. Access to the wireless network is limited to devices associated with an authorized personnel when the authorized personnel is determined to be within the secured area and denied to devices associated to personnel determined to be outside the secured area.

Abstract: A method and apparatus for providing a security system. The method includes the steps of providing an identity card for use by a person entering a secured area of the security system, reading the identity card at an entry point to the secured area, randomly generating an alphanumeric key upon the occurrence of a predetermined event, writing the alphanumeric key into the identify card at the entry point, reading the card within the secured area as a request for access to a computer and granting access to the computer by the person, but only when an alphanumeric key is found on the card that matches the generated alphanumeric key.

Abstract: A route planning system is provided. The system includes a mapping processor that extracts geometric information about a building from a building model of the building and generates an adjacency map of adjacent areas from the extracted information, a triangulation processor that translates each adjacent area of the adjacency map into a closed polygon representation and splits the closed polygon representation into a minimal group of triangles that covers the area where each triangle of the minimal group of triangles includes adjacency information derived from the adjacency map, a user interface that receives first and second locations within the building and a route processor that defines a route between the first and second locations by identifying a minimum set of triangles from the triangles that together form a continuous path between the first and second locations based at least upon the triangle adjacency information.

Abstract: A method and apparatus are provided for controlling access to a secure area. The method includes the steps of providing a plurality of user credentials, generating a Boolean equation based upon the plurality of user credentials where the generated Boolean equation provides a predetermined response to each user credential of the plurality of credentials, saving the generated Boolean equation in a memory in place of the user credentials and recognizing a user credential of the plurality of user credentials by reference to the Boolean equation.

Abstract: A method and system for dynamic association of security levels and enforcement of security procedures. A secure object can be tracked across a building or complex, and security levels may be dynamically updated to reflect the new security requirement. In response to the security level adjustment, security measures and protocols may be implemented dynamically. The system comprises a sensitivity index assigned to each of a plurality of secure objects, a scanner for detecting the sensitivity index, and a logic unit in communication with the scanner for determining a security level for the secure area based on the sensitivity indices of the plurality of secure objects within the secure area. The method comprises detecting a plurality of secure objects within a secure area, each secure object having a sensitivity index, and determining a security level for the secure area based on the sensitivity indices of the plurality of secure objects within the secure area.

Abstract: A method and apparatus is provided for generating reports for ensuring process compliance. The method includes the steps of receiving a sign-in event notification for a process, identifying a set of rules for controlling the process based upon a source of the sign-in notification, receiving a sign-out event notification for the process and associating a set of images from the area recording portions of the process with an event report in accordance with the identified rules.
