    Abstract: An electroformed sheath for protecting an airfoil includes a sheath body and a mandrel insert is provided. The sheath body includes a leading edge. The sheath body includes a pressure side wall and an opposed suction side wall, which side walls meet at the leading edge and extend away from the leading edge to define a cavity between the side walls. The sheath body includes a head section between the leading edge and the cavity. The mandrel insert is positioned between the pressure side and suction side walls, and includes a generally wedge-shaped geometry. A method for protecting an airfoil includes: 1) securing a mandrel insert to a mandrel; 2) electroplating a sheath body onto the mandrel and the mandrel insert; 3) removing the mandrel from the sheath body so that a sheath cavity is defined within the sheath body; and 4) securing the airfoil within the sheath cavity.

  • Patent number: 9960865
    Abstract: A station (STA) can receive messages (e.g., beacon frames) at a regular interval, and perform measurements on the received messages. The STA maintains a running average of recent measurement values, and updates the running average after each new measurement interval. At some measurement opportunities, the expected messages cannot be received by the STA, and so the STA cannot perform a measurement; when this occurs, the STA can choose substitute values to use for the missed measurements when next calculating the running average. As one example, the STA can substitute the value for a previously-performed measurement for the missed measurements. As another example, the STA can substitute a predetermined low value for the missed measurements. Based on the value of the running average at a given point in time, the STA can take actions such as initiating a roaming scan or switching to a different wireless interface.

  • Patent number: 9596637
    Abstract: In order to facilitate communication between an electronic device and another electronic device, the electronic device determines communication-quality metrics for a first connection in a wireless network based on received information from the other electronic device. Then, the electronic device calculates an overall communication-quality indicator for the first connection based on at least some of the communication-quality metrics. Moreover, the electronic device dynamically adapts the communication with the other electronic device based on the overall communication-quality indicator. For example, the electronic device may establish a second connection in a cellular-telephone network and may use the second connection to communicate with the other electronic device.

  • Patent number: 9516483
    Abstract: A method for wireless communication between stations of differing protocols begins by determining whether protocols of target stations of a wireless communication are different than a protocol of a source station. The method continues by, when at least one of the target stations has a different protocol than the protocol of the source station, determining whether the wireless communication is a direct wireless communication or an indirect wireless communication. The method continues with the source station transmitting a frame to an access point, wherein the frame is formatted in accordance with the protocol of the source station, when the wireless communication is the indirect wireless communication. The method continues with the access point converting the frame into at least one alternate frame based on the protocol of the at least one of the target stations having the different protocol.

  • Publication number: 20160212575
    Abstract: Protocol adaptation layer for wireless communications. Communication devices that include one or more radio modules operable in accordance with multiple communication protocols establish communications using one communication protocol and then switch to another communication protocol. This switching to another communication protocol may be performed based on a variety of factors including effectuating communications of higher throughput, supporting uni-directional communications vs. bi-directional communications, or any other desired factor. In some embodiments, various communication devices include two radio modules that are each implemented to operate in accordance with one particular communication protocol. Alternatively, a multi-protocol capable radio module may support and operate in accordance with more than one communication protocol. Examples of possible communication protocols include those compliant with Bluetooth, IEEE 802.11, and/or 802.15.3c.

  • Patent number: 9344535
    Abstract: A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.

  • Patent number: 9300368
    Abstract: Information may be communicated between two or more wireless devices via adaptive or steered antennas or antenna systems and 60 GHz signals. The adaptive or steered antennas or antenna systems may be initialized based upon location information determined from a beacon signal and/or a reference system. The beacon signal may be swept through an angle and may be utilized along with reference system information to determine the direction and/or distance between the two or more wireless devices. Spatial relationships between the two or more wireless devices may vary. The two or more wireless devices may communicate and coordinate communications between them via alternate lower frequency signals.

  • Patent number: 9247439
    Abstract: A method for receiving a frame in a high data throughput wireless local area network begins by receiving a preamble of the frame via a channel in accordance with a default receiver filter mask. The processing continues by validating the preamble. The processing continues by, when the preamble is validated, interpreting the preamble to determine a high data throughput channel configuration. The processing continues by reconfiguring the default receiver filter mask in accordance with the high data throughput channel configuration to produce a reconfigured receiver filter mask. The processing continues by receiving a data segment of the frame in accordance with the reconfigured receiver filter mask.

  • Patent number: 9198035
    Abstract: An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. In another embodiment, a direct link comprising direct packet transfers without beaconing is performed between the multi-mode device and another multi-mode device. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link or over an IEEE 802.11 direct communication link.

  • Patent number: 9191092
    Abstract: Aspects of the invention described herein may enable a greenfield access mode in IEEE 802.11n WLAN systems in comparison to an alternative approach that may not provide greenfield access. The utilization of greenfield access may reduce the portion of time required to transmit data due to overhead comprising preamble fields and header fields. This may enable higher data throughput rates to be achieved. This may further enable more robust transmission of data by enabling comparable data rates to be maintained while reducing the coding rate of encoded transmitted data. The reduction of the coding rate may enable comparable data rates to be maintained for transmission via RF channels characterized by lower SNR while still achieving desired target levels of packet error rates. In another aspect of the invention, mixed mode access may be achieved while reducing the portion of time required for transmitting data due to overhead.
