Abstract: Multiple methods for determining a location of a STA operating on a mesh wireless network are described herein. A STA finder is used to monitor changes in received signal strength at each access point of a group of access points operating the mesh wireless network. The changes in received signal strength are then utilized to determine a location of STAs operating on the mesh wireless network. Methods for identifying poor performance areas on the mesh wireless network using the position information and then providing recommendations for improving the performance of the mesh wireless network are also described herein.

Abstract: Disclosed is a method for selecting a path in a communication network. The method comprises transmitting, through a device connected to a target node, a beacon, to one or more nodes in the communication network. The beacon comprises a set of informative parameters. The method comprises calculating, by each node, a selective score towards one more paths to be selected for reaching the target node in the communication network. The method further comprises identifying, by each node, a target path from the one or more path. The target path is a path having a highest value of the selective score as compared to selective score for other paths in the one or more paths. The method further comprises selecting, by each node, the target path from the one or more paths for reaching the target node.

Abstract: A wireless device operates as both a station and one or more access points. In the wireless device, a scan window of a specified duration is requested to start at a first time, to scan for access points external to the wireless device in accordance with operation of the wireless device as a station. It is determined that a beacon scheduled for transmission or reception at a second time conflicts with the requested scan window. In response, the beacon is transmitted or received at the second time and at least a portion of the scan window is delayed until after the beacon has been transmitted or received.

Abstract: Systems and methods are provided for enhancing the concurrency of a wireless device operating in multiple network contexts. At least one virtual interface may be implemented for each network context. A recurring communication event having a defined interval associated with one of the network contexts may be identified and the interval may be time divided into multiple operation periods, such that each operation period corresponds to one of the virtual interfaces. Accordingly, each virtual interface may be given access to the physical transceiver during the corresponding operation period. As desired, the operation periods may be subdivided into one or more slots, which may be associated with different priorities of communication.

Abstract: This disclosure provides implementations of electromechanical systems resonator structures, devices, apparatus, systems, and related processes. In one aspect, a sacrificial layer is deposited on an insulating substrate. A lower electrode layer is formed proximate the sacrificial layer. A piezoelectric layer is deposited on the lower electrode layer. An upper electrode layer is formed on the piezoelectric layer. At least a portion of the sacrificial layer is removed to define a cavity such that at least a portion of the lower electrode layer is spaced apart from the insulating substrate.

Abstract: A sheet film protective covering for different types of contour sensing devices is described. In a preferred embodiment, this covering is a Mylar sheet film that is coated with a layer of a conductive material. The bottom surface of the Mylar film is also preferably coated with a layer of an adhesive. The sheet film covering preferably is contiguous and serves the purpose, among other things, to protect the underlying surface of the pressure-sensing device from contaminants and from electrostatic discharge, as well provide force concentration during use.

Abstract: A sensor for a textured surface (e.g., a fingerprint) is provided. The sensor includes a flexible substrate and a flexible membrane supported above the substrate by one or more spacers. The sensor also includes multiple pressure sensor elements responsive to a separation between parts of the membrane and corresponding parts of the substrate. The membrane is conformable to the textured surface being sensed, so the variation in separation between substrate and membrane is representative of the textured surface being sensed. Such pressure sensors can be included in fingerprint authentication subsystems including associated integrated electronic circuitry (e.g., encryption, image processing, fingerprint matching, communication and/or location determination circuitry). Such subsystems can be included in various access control systems (e.g., smart cards and mobile electronics).

In one embodiment, the method is directed to a sensor that that is protected from external contaminating particulates and will self-equalize using air from outside the sensor. Further combinations of such protection among various membrane switches, in combination with various types of membranes, is described. In another embodiment, a method of making a skin-texture sensor for sensing a skin texture having a plurality of ridges and a plurality of valleys is described, such that when completed, applying a ridge of the texture to a membrane switch will cause flexure of the membrane resulting in a contact between the lower electrode and the upper electrode, the contact establishing an electrical communication between said one of the row lines and said one of the column lines, whereas disposing a valley of the texture over said each membrane switch will not result in the contact between the lower electrode and the upper electrode.

Once provided, the method then includes sensing a resistance in the plurality of layers upon application of pressure to the sensing device, the applied pressure causing the magnetization vector of the magnetoresistive layer to change and thereby result in a change in resistance.
