20130000488 | Composite hollow ceramic fibers, precursors for, methods of making the same, and methods of using the same - A composite hollow ceramic fiber includes a porous hollow core supporting a thin, dense sheath. The non-gas-tight core comprises a first ceramic compound and an interconnecting network of pores. The gas-tight sheath comprises a second ceramic compound. The fiber is made by extruding first and second suspensions of the first and second ceramic compounds in polymeric binders and solvent from a spinnerette and coagulating the nascent hollow fiber to effect phase inversion of the polymeric binders. The resultant green fiber is sintered in a two step process. First, the binder is burned off. Second, the sheath is densified and the second ceramic compound is sinter without fully sintering the first ceramic compound. The first ceramic compound has a melting point higher than that of the second ceramic compound. | 01-03-2013 |

20130077779 | ENABLING WIRELESS CLIENTS FOR LOW-POWER OPERATION WHEN CLIENTS REQUIRE CONTROL MESSAGES FROM EXTERNAL SOURCES FOR COMMUNICATION - A wireless station (A) is operated in a power-save mode, in which the station is alternately in power-ON and power-OFF states to reduce power consumption. Wireless station (A) computes at least some future time instances at which another wireless station (B) is expected to start transmitting control messages. Wireless station (A) is ensured to be in the power-ON state in corresponding time intervals encompassing durations of at least some of such future transmissions of control messages by wireless station (B), and is thereby enabled to receive the control messages. In an embodiment, the control messages correspond to group key message updates in which values of a decryption key are transmitted, wireless station (A) being a wireless client, wireless station (B) being an access point, with wireless stations (A) and (B) operating in a wireless network consistent with IEEE 802.11 specifications, and communication between wireless stations (A) and (B) being encrypted. | 03-28-2013 |
20130272180 | CORRECTION OF CLOCK ERRORS IN A WIRELESS STATION TO ENABLE REDUCTION OF POWER CONSUMPTION - According to an aspect, a wireless station uses a low-frequency clock during sleep intervals and a high-frequency clock during awake intervals. Drift between the low-frequency clock and the high-frequency clock are corrected to enable aligning a wake time instant of the wireless receiver with start of beacon transmissions from an access point, and thereby to reduce power wastage. According to another aspect, errors between the clock of an access point and that of a wireless station are corrected. The wireless station computes an error between the clocks, and extrapolates the error for a sleep interval to compute a wake-up time instant. The correction and extrapolation are performed in every awake interval. Again, undesired power consumption in the wireless station is thereby reduced. | 10-17-2013 |
20130294303 | REDUCING POWER CONSUMPTION IN A DEVICE OPERATING AS AN ACCESS POINT OF A WIRELESS LOCAL AREA NETWORK - An access point communicates with a wireless station based on a point-to-point channel, to determine time instances of future communication to be received from the wireless station. In intervals between such future communications, the access point powers down at least some portions of a circuit contained within the access point for at least a partial duration between such future communications. In an embodiment, the powered-down portions include the receiver portions of the access point. The access point may be battery-powered, and the powering-down of the receiver portions enables reduction of power consumption in the access point. | 11-07-2013 |
