Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.

Abstract: A process for mechanical destructuring of cellulosic biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications.

Abstract: A constant voltage dimmable LED (Light Emitting Diode) driver is disclosed that is compatible with all types of dimmers, including conventional phase cut (TRIAC) dimmers, and behaves like a conventional constant voltage driver which can be connected to any size of LED load that has a matching voltage rating. The driver produces a continuous train of pulses for driving the LED load and obtains an averaged measure of the voltage at the AC input for controlling the duty cycle of the continuous train of pulses. Therefore, when the averaged measure of the voltage at the AC input is reduced by a dimmer, the duty cycle reduces, resulting in a dimmed LED. The driver can be created by adding a few components to a conventional wide input range AC-DC converter without or with very little modifications.
