  3. Multiple Access with Collision Avoidance for Wireless

    en.wikipedia.org/wiki/Multiple_Access_with...

    Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol. [3] [4] It uses RTS-CTS-DS-DATA-ACK frame sequence for transferring data, sometimes preceded by an RTS-RRTS frame sequence, in view to provide solution to the hidden node ...

    en.wikipedia.org/wiki/Timing_synchronization...

    Timing synchronization is achieved by stations periodically exchanging timing information through beacon frames. In (intra) BSS, the AP sends the TSF information in the beacons. In Independent Basic Service Set (IBSS, ad-hoc), each station competes to send the beacon. Each station maintains a TSF timer counting in increments of microseconds (μs).

    RIFS is used when no SIFS separated response frames are expected from the receiver. The value of RIFS is 2μs for 802.11n phy. [1] The use of RIFS is obsolete from 802.11ac amendment onwards. [2] An 802.11ac station will not transmit frames separated by RIFS. So a 11ac station operating in HT mode sets the RIFS mode field in HT operation ...

    This included a subset of configurable settings called "convenience settings" as well as other settings that adapted according to the programs and devices installed on the Lisa Office System. The original control panels in the earliest versions of the classic Mac OS were all combined into one small Desk Accessory .

  8. Remote Skylights - Wikipedia

    en.wikipedia.org/wiki/Remote_Skylights

    Remote skylights are composed chiefly of a solar collection dish, a "heliotube" and a distribution dish. [1] The collection and distribution dishes are both parabolic reflectors . The collection dish is connected to a heliostat , a mechanism which tracks the transit of the sun across the sky, so as to maximize the intensity of light falling ...

    A retractable skylight rolls (on a set of tracks) off the frame, so that the interior of the facility is entirely open to the outdoors, i.e., not impeded by a hinged skylight. The terms retractable skylight and retractable roof are often used interchangeably, though skylight implies a degree of transparency. Tubular daylight device
