20160037484 | SYSTEMS AND METHODS FOR MULTI-USER SIMULTANEOUS TRANSMISSIONS - Systems, methods, and devices are provided for protecting a multiuser (MU) transmission between an access point and a plurality of wireless stations. The access point may transmit a frame that is addressed to multiple stations in a wireless network. Each of the stations addressed by the frame may respond with an identical clear-to-send frame. In some instances, the clear-to-send frames transmitted by each wireless station may utilize the same scrambling code utilized by the frame transmitted by the access point, use the same modulation and coding scheme, and/or occupy the same frequency bands such that the multiple clear-to-send frames are combined in the air and detected as a single frame by the access point. In some instances, the access point may thereafter transmit an uplink reference frame to trigger the wireless stations to transmit an uplink data request frame to the access point. | 02-04-2016 |
20160080954 | DISTRIBUTED ADAPTIVE CCA MECHANISMS - A method implemented by a first network device where the method provides an adaptive clear channel assessment (CCA) by collecting a neighboring network device set for a wireless local area network (WLAN). The method detects a wireless signal from a second network device on a wireless medium. A signal quality of the wireless signal is then determined. An identity of the second network device is also determined. The second network device is then added to the neighboring network device set of the first network device, in response to determining that the second network device is a neighbor based on the signal quality of the wireless signal. | 03-17-2016 |
20160087775 | ACKNOWLEDGMENT MECHANISMS FOR OFDMA OPERATION - In an example of wireless communications based on orthogonal frequency-division multiple access (OFDMA), an access point may send a downlink frame to multiple stations. In response, some or all of the stations may transmit their respective uplink frames simultaneously after a predetermined time period. The uplink frames from the stations may be aggregated or multiplexed to form a final uplink frame that is received by the access point. Each of the uplink frames from the stations may include at least a legacy header and an acknowledgment frame. While a legacy header occupies the entire channel bandwidth of its uplink frame, an acknowledgment frame occupies a sub-band assigned to its station, where a sub-band is a portion of the channel bandwidth. Other methods, apparatus, and computer-readable media are also disclosed. | 03-24-2016 |

20110047681 | PROTECTIVE EYEWEAR DEVICE WITH LATERAL EYE ACCESS - Disclosed herein are protective eyewear device embodiments that enable lateral access to the eye while at the same time shielding the eye from other directions. The protective eyewear device embodiments are particularly suitable for water activities as they allow air flow between the user and the device, thereby avoiding fogging of the lens. As water eventually enters in between the user and the device, which ultimately interferes with the eyes of the user, the user can wipe the eyes via the lateral access without actually having to remove the protective eyewear device. | 03-03-2011 |

20090086645 | APPARATUS AND METHOD FOR PASSIVELY ANALYZING A DATA PACKET DELIVERY PATH - A packet transmission diagnostic system transmits diagnostic packets during a communications session in which data packets are transmitted between a source and destination. The diagnostic packets elicit responses from routers along a path between the source and destination. The elicited responses, in the form of packets, are used by the diagnostic system to produce one or more packet-delivery metrics for one or more of the routers along a packet transmission path between the source and destination. | 04-02-2009 |
