Abstract: A system including a physical layer module and a control module. The physical layer module is configured to generate a first clear channel assessment for a first sub-channel of a communication channel and generate a second clear channel assessment for a second sub-channel of the communication channel. The first clear channel assessment indicates whether the first sub-channel is free or busy. The second clear channel assessment indicates whether the second sub-channel is free or busy. The control module is configured to, in response to the second sub-channel being busy, extend a duration of the second clear channel assessment by a predetermined period of time, and transmit data via (i) only the first sub-channel or (ii) both the first sub-channel and the second sub-channel based on (a) the first clear channel assessment, (b) the second clear channel assessment, and (c) the extended duration of the first clear channel assessment.

Abstract: A system includes a signal processing module and a control module.

The control module receives the second CCA signal and a third CCA signal for a second sub-channel of the communication channel. The control module transmits data via one of the second sub-channel and the communication channel based on the second and third CCA signals.

Abstract: A process for the preparation of new polyols and polyesters from a natural oil or other unsaturated fatty acid esters is described. The process involves ozone cleavage of double bonds in the fatty acid chains of the oils along with coupling of a hydroxylated compound such as a mono-alcohol, a diol, or a polyol to the cleaved ends of the molecules resulting from the cleavage with a base. The resulting polyols and polyesters are as intermediates for polymers.

Abstract: A wireless network device having active and inactive modes comprises a clock generating module that generates a first clock signal having a first clock rate. A voltage supply module generates a first voltage level and a second voltage level that is less than the first voltage level. A first digital module receives the first clock rate and the first voltage level during the active mode, receives the second voltage level during the inactive mode and does not receive the first clock signal during the inactive mode. A first analog module communicates with the voltage supply module and has reduced current consumption during the inactive mode.

Abstract: A low power E-fuse repair methodology substantially removes system latency during memory and/or E-fuse farm module power-down in a device that employs E-fuse farm technology. The method maintains power to the repair registers and minimal control logic in the memories, while all other circuitry can be either placed in a low power data retention mode, or completely powered off. There is no need to rescan the repair data from the E-fuse farm after one or more memories are powered back up. This provides dynamic power savings since there is no longer any need to idle the system to reload repair data. Since the E-fuse farm can be powered down after initial system power-up and repair data is loaded into the memories, there is also a significant leakage power savings.

Abstract: An embodiment of a ultra low-power data retention latch circuit involves a slave latch SL that concurrently latches the same data that is loaded into a main circuit (such as a main latch ML) during normal operation. When the circuit enters a low power (data retention) mode, power (VCC) to the main latch ML is removed and the slave latch SL retains the most recent data (retained data SA, SA-). When power is being restored to the main latch ML, the slave latch's retained data SA, SA- is quickly restored to the main latch ML through what constitute Set and Reset inputs SAR, SAR- of the ML. This arrangement ensures that data restoration is much quicker than conventional arrangements that require the output data path DATA- to be stabilized before power is re-applied to the main latch. Further, there is no need to wait for power to the ML to be stable before restoring data from the SL to the ML, providing an increase in data restoration speed over conventional data retention latches.
