Abstract: A process and system for producing a fermentable gas stream from a gas source that contains one or more impurity which may be harmful to the fermentation process is provided. To produce the fermentable gas stream, the gas stream is passed through a specifically ordered series of removal beds. The removal beds remove and/or convert various impurities found in the gas stream which may have harmful effects on downstream removal beds and/or inhibitory effects on downstream gas fermenting microorganisms. At least a portion of the fermentable gas stream may be capable of being passed to a bioreactor, which contains gas fermenting microorganisms.

Abstract: Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.

Abstract: Methods and systems described herein are directed to automatedly generating entity-specific notifications of a vehicle accident occurrence for entities. In response to a notification system receiving accident data, the system can determine characteristics for the accident occurrence. Using these characteristics, the system can then determine parameters for the notifications defining types of entities which ought to be recipients in accordance with the characteristics. The system can use these parameters to locate specific entities that match the parameters. Having determined the entities, the system can issue notifications to the entities, using templates specific to the entities and with accident characteristics added.

Abstract: A fabrication of a build structure by an additive layer manufacturing machine is assessed and controlled. A first portion of a first material is selectively heated to form a first formed layer of the build structure having a first thickness. An image of a predefined region of the first formed layer is generated. The image depicts topographical characteristics within the predefined region of the first formed layer. A subsequent portion of the first or a second material is selectively heated to form a subsequent formed layer of the build structure attached to the first formed layer. The subsequent formed layer has a second thickness that correlates with the depicted topographical characteristics.

Abstract: A method and system for selecting a sub-band in a television white space frequency band may include configuring an antenna matching circuit based on the selected sub-band and configuring a bandpass filter based on the selected sub-band. The method may include receiving a first signal through a radio-frequency path including the antenna matching circuit and not including the bandpass filter, measuring a parameter of received first signal, and determining whether the selected sub-band is usable based on the measured parameter of the received first signal. The method may include receiving a second signal through radio-frequency path including the antenna matching circuit and the bandpass filter, measuring a parameter of the received second signal, and determining whether the selected sub-band is usable based on the measured parameter of the received second signal.

Abstract: A radiofrequency (RF) power regulator includes a forward RF power detection circuit to detect forward RF power supplied by an RF transmitter circuit to an RF transmitting antenna. An RF power sampler is coupled to the forward RF power detector circuit and provides RF power samples of the supplied forward RF power. Multiple filters are coupled to receive the RF power samples. Each filter differently filters the received forward power samples to apply a different average power period. Each filter activates an RF power adjustment trigger signal while a time-averaged forward RF power supplied to the RF transmitting antenna satisfies a forward RF power adjustment condition for the average power period of the filter. Forward RF power adjustment logic is coupled to filters and operable to adjust the forward RF power supplied by the RF transmitter circuit to the RF transmitting antenna based on the RF power adjustment trigger signal.

Abstract: A first encapsulation protocol processing component (EPPC) at a particular device of a virtualized computing service establishes a network packet tracking session with a second EPPC at another device. The first EPPC tags at least some encapsulation packets (which contain baseline packets generated at or directed to guest virtual machines) sent to the second EPPC as tracked packets. The first EPPC obtains network metrics corresponding to the tracked packets of the session from the second EPPC, prepares network health updates based on the metrics, and send the updates to a network health management service associated with the virtualized computing service.

Abstract: Radio Frequency (RF) power back-off optimization techniques are described for specific absorption rate (SAR) compliance. A mobile device may be configured to intelligently modify antennas and radio device transmission levels to maintain compliance with SAR limits while minimally perturbing radio operations. The mobile device may implement a SAR optimization scheme that accounts for user presence and signal conditions to maintain compliance. Rather than setting a fixed back-off, user presence detectors may be employed along with information on current signal conditions to determine potential for excessive SAR exposure and selectively apply variable adjustments to RF transmission power (e.g., “back-offs”), accordingly. The mobile device may also be configured to report SAR conditions and/or mitigation actions to a base station to enable the base station to manage a connection to services based at least in part upon knowledge of SAR actions taken by the mobile computing device.

Abstract: The subject invention relates to a novel gene referred to herein as DSM-2. This gene was identified in Streptomyces coelicolor A3. The DSM-2 protein is distantly related to PAT and BAR. The subject invention also provides plant-optimized genes encoding DSM-2 proteins. DSM-2 can be used as a transgenic trait to impart tolerance in plants and plant cells to the herbicides glufosinate and bialaphos. One preferred use of the subject genes are as selectable markers. The use of this gene as a selectable marker in a bacterial system can increase efficiency for plant transformations. Use of DSM-2 as the sole selection marker eliminates the need for an additional medicinal antibiotic marker (such as ampicillin resistance) during cloning. Various other uses are also possible according to the subject invention.
