Abstract: Backward compatibility may require the use of fields or other indicators that are interpreted by new nodes or stations in a system in a manner different from the way legacy nodes interpret those same fields. In some circumstances, these indicators may be used to 'spoof' legacy nodes to behave in certain ways, to allow a next generation protocol to be performed without interference from those legacy nodes. While this practice is may increase communication effectiveness, spoofing may lead to inefficient operation of legacy nodes. Legacy nodes may detect spoofing, including detecting field settings in a legacy portion of a transmitted message, or detecting phase shifts in a message. Once spoofing is detected, a variety of steps may be taken, including determining the duration of the next generation message, entering a low power state for the duration, communicating on alternate channels for the duration, modifying legacy backoff procedures, and others.

Abstract: A somewhat flexible floor assembly is supported by a matrix of spaced-apart vertically-adjustable devices, such as electrically-operated jacks operated by servo motors. The devices are centrally individually controlled whereby height of the devices may be individually varied so that the floor surface may have its contour varied as desired.  Somewhat flexible metal rods are supported by the jacks, and they in turn support joist assemblies which support a subfloor and flooring surface. The vertically-adjustable devices may be controlled by a computer, which may access data corresponding to a number of selectable pre-configured contours, such that selection of one of the pre-configured contours causes the height of the devices to vary so as to move the floor surface to a configuration corresponding to the selected pre-configured contour. The pre-configured contour may be, for example, a simulation of a real-life golf green.

Abstract: A single screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of a slide instead of to the discharge port.  The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the slide further allows the use of an offset discharge port in the casing, in relation to the main rotor. This means that pressure acting through the discharge port in use of the compressor tends to press the slide against another structure than the main rotor, for instance a bearing housing, giving better support to the slide. The slide also provides an improved oil delivery arrangement

Abstract: A process is provided for increasing the production of PHA in a mixed culture biomass. In a first stage of the process, organic material associated with a substrate is converted to volatile fatty acids, In the case of a wastewater treatment process, if the wastewater includes sufficient volatile fatty acids (VFAs) to support the process, then it is unnecessary to convert organic material to VFAs. In a second stage of the process, an anaerobic-aerobic selection process is utilized to select glycogen accumulating organisms that cause these organisms to proliferate and dominate the open mixed culture biomass. By providing relatively high organic loading in the form of VFAs in the anaerobic treatment phase of the selection process, glycogen accumulating organisms having a relatively high level of stored glycogen are produced. In a third stage, the PHA accumulation process is practiced where the glycogen rich organisms are fed VFAs under anaerobic or aerobic conditions or combinations thereof. Through the consumption of externally supplied VFAs and internally stored glycogen, relatively high levels of PHA in the biomass are produced.  Thereafter PHA is separated from the residual biomass.
