1. A filter assembly for use in an electronic enclosure, the filter assembly configured to remove contaminants within the electronic enclosure and to prevent entry of contaminants into the electronic enclosure, the filter assembly comprising:
a housing, configured for placement in an electronic enclosure containing a rotating disk, the housing comprising:
an air scoop configured to direct airflow through a filter material, the air scoop having an entrance configured for placement proximate to the rotating disk in the electronic enclosure; and
a major surface comprising a wall having an opening configured for receiving a filter material and being in fluid communication with the entrance to the air scoop; and
a filter element positioned within the housing and covering the opening in the major surface, the filter element having first and second portions, where the portion of the element is configured to filters air directed from the air scoop and the second portion of the element is configured to filters air from the exterior of the electronic enclosure.
2. The filter assembly of claim 1, wherein the housing defines a cavity configured to receive an adsorbent material, the cavity being in fluid communication with the entrance to the air scoop and with the opening in the wall of the major surface of the housing.
3. The filter assembly of claim 2, wherein the cavity is bisected by a divider to define a recirculation portion and a breather portion.
4. The filter assembly of claim 1, wherein the opening in the wall of the major surface of the housing is in fluid communication with the interior of the electronic enclosure.
5. The filter assembly of claim 1, wherein the opening in the wall of the major surface of the housing is integrally formed with the electronic enclosure.
6. A filter assembly for use in an electronic enclosure, the filter assembly comprising:
(a) a housing defining an air inlet, an air scoop, an air outlet, and a channel connecting the air scoop with the air outlet, the air scoop being configured to direct airflow through a filter material; and
(b) a dual purpose filter comprising:
(i) a breather filter element positioned within the housing and in fluid communication with the air inlet and the air outlet, the breather filter element positioned to filter air entering the electronic assembly; and
(ii) a recirculation filter element positioned over the air outlet to filter air circulating within the electronic enclosure.
7. The filter assembly of claim 6, wherein the dual purpose filter comprises at least one common layer between the breather filter element and the recirculation filter element.
8. The filter assembly of claim 6, wherein the housing comprises a major surface having a wall and an opening in the wall, the opening configured for receiving a filter material and being in fluid communication with the entrance to the air scoop.
9. The filter assembly of claim 8, wherein the opening in the wall of the major surface of the housing is exposed to the interior of the electronic enclosure.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of communicating in first and second wireless local area networks comprising:
operating as an access point of the first wireless local area network, wherein the first wireless local area network is operating in a first frequency band;
transmitting a message including one of a null message, a ready to send (RTS) or clear to send (CTS) command, over the first wireless local area network during a predetermined time interval, wherein the transmitting of the message causes stations of the first wireless local area network to refrain from transmitting during the predetermined time interval; and
during said predetermined time interval, operating as a network bridge with a device of the second wireless local area network wherein the second wireless local area network is operating in a second frequency band.
2. The method of claim 1, further comprising:
extending the predetermined time interval to enable communications with the device of the second wireless local area network.
3. The method of claim 1, further comprising:
periodically transmitting the message, with a first time interval between transmissions, wherein the first time interval is based on an estimation of a second time interval of a beacon transmission of the second wireless local area network.
4. The method of claim 1, further comprising:
buffering communications related to the device of the second wireless local area network while communicating with the device of the first wireless local area network.
5. The method of claim 1, further comprising:
while operating as the access point of the first wireless local area network, simulating a standby or power saving mode with respect to at least one device of a second wireless local area network.
6. The method of claim 1, further comprising:
broadcasting as the access point of the first wireless network a message to mobile units of the first wireless local area network containing a request to cease transmission for said predetermined time interval.
