Abstract: Digital predistortion (DPD) arrangements that use coding to differentiate between contributions from individual power amplifiers (PAs) is disclosed. When used with a phased antenna array having N antenna elements and N corresponding PAs, the arrangements may sequentially apply N codes to input signals provided to N PAs. Each code is a vector having N elements, where each element corresponds to a different PA in that the element is a complex gain applied to an input signal for the PA. Together, the N codes may be arranged as N rows or N columns of a matrix P. The disclosed arrangements may generate N feedback signals by applying the matrix P to a signal generated by a probe antenna element sensing wireless RF signals transmitted by the N antenna elements, and to update DPD coefficients based on the N feedback signals. The N codes may be either orthogonal or non-orthogonal.

Abstract: A compression roller device includes markers on roller heads for pressure-rolling over a substrate to form visual indicia that the substrate has been properly pressure-rolled. In example embodiments, there are two roller heads that each have a set of markers and that are spaced-apart with a handle center-mounted between them. In this way, the roller heads have free/unobstructed outer/opposite edges so they can be positioned closely against an obstructing surface or element for rolling substrates in tight spots with limited clearance. Also, the recess defined between the inner/facing edges of the roller heads provides clearance for rolling over any protruding fasteners securing the substrate in place. Further, the spaced-apart marker sets provide for marking the visual indicia on both sides of a seam/joint between two adjacent panels in a panel-and-tape system to show that both longitudinal side portions of the tape have been pressure-rolled.

Abstract: A rotary steerable tool is provided for use with a drilling apparatus. The rotary steerable tool includes at least a first portion that includes an outer housing, a rotary shaft extending through the outer housing, a drive clutch coupled to the rotary shaft, and a sensor coupled to the rotary shaft. The drive clutch is movable between an engaged configuration and a disengaged configuration. The sensor is configured to identify whether the drive clutch is in at least one of the engaged configuration and the disengaged configuration.

Abstract: An air delivery system includes a controllable flow generator operable to generate a supply of pressurized breathable gas to be provided to a patient for treatment and a pulse oximeter configured to determine a measure of patient effort during a treatment period and provide a patient effort signal for input to control operation of the flow generator.

Abstract: Components of a CPAP or other patient ventilation apparatus have a remotely-readable identification tag encoded with component identification data. The flow generator controller 40 is programmed to receive data derived from the identification tag from a tag reader, and to adapt functions of the flow controller to coordinate with the component.

Abstract: The invention provides a method for inhibiting hemoprotein- and heme-induced lipid peroxidation, a method for identifying compositions that are effective to inhibit hemoprotein- or heme-induced lipid peroxidation, and methods of therapeutic use for those compounds.

Abstract: A new and distinct Echeveria cultivar named ‘Joey2’ is disclosed, characterized a multiple, self-initiating branching habit, strong, uniform leaf color over a wide temperature range and under low water stress. Additionally, the new variety produces a high number of flower stems, with the peak amount in spring. The new variety is an Echeveria, typically produced as a garden or container plant.

Abstract: A new and distinct Echeveria plant named ‘MOBEc 69’ which is characterized by succulent foliage tightly held in a basal rosette, light blue-green foliage which is lightly margined red, and significantly delayed development of clonal offsets. The new variety has shown to be uniform and stable in the resulting generations from asexual propagation.
