摘要： A speaker enclosure, or enclosure, and kit with plural linearly aligned panels connected by flexible couplings are shipped in a parallel stack with all the coupled panels still coupled during shipment, plus additional panels, also stacked parallel. The flexible couplings may be provided by a single sheet of flexible substrate coupled to the linearly aligned panels. One side of the assembled speaker enclosure includes a middle panel of the coupled panels, having at least one flat rabbet joint. The external length of the middle panel is long enough to permit folding of at least one of the outermost of the panels, with flexible substrate and a covering, under the middle panel. The assembled speaker enclosure is held together with a flexible substrate, adhesive, clamps, or preferably, any two thereof. Openings for speakers and connector cups are provided. The kit includes adhesive, instructions, at least one connector cup, and hardware.

摘要： A collapsible and adjustable electronics support with a releasably lockable rotatable base having a link with adjustable drag hinges connecting the releasably lockable rotatable base to a receiver for a polygonal support adapter. One or two tools for adjusting the drag hinges are included with first and second releasably snap-fit covers for respective first and second link sides of the link. The covers also cover the adjustable device in the drag hinge ends. The releasably lockable rotatable base is a four-part base with an adhesive part, a flexible and resilient panel supporting an axle, a first rigid panel rotationally fixed relative to the flexible and resilient panel, and a second rigid panel that rotates relative to the first rigid panel. The low profile in a collapsed configuration avoids rubbing the environmental surface to which it is attached. Wire management guides are provided on the receiver.

摘要： A Radio Frequency (RF) structure services an antenna having a characteristic impedance and includes a differential Power Amplifier (PA), a differential Low Noise Amplifier (LNA), and a balun transformer. The differential PA has a differential PA output with a PA differential output impedance. The differential LNA has a differential LNA input with an LNA differential input impedance. The balun transformer has a singled ended winding coupled to the antenna, a differential winding having a first pair of tap connections coupled to the differential PA output and a second pair of tap connections coupled to the differential LNA input, and a turns ratio of the single ended winding and the differential winding. The turns ratio and the first pair of tap connections impedance match the PA differential output impedance to the characteristic impedance of the antenna. The turns ratio and the second pair of tap connections impedance match the LNA differential input impedance to the characteristic impedance of the antenna.

摘要： A method for temperature compensation of transmit power of a wireless communication device begins by measuring transmit power of the wireless communication device at a first temperature-based biasing condition to produce a first measured transmit power. The method continues by measuring transmit power of the wireless communication device at a second temperature-based biasing condition to produce a second measured transmit power. The method continues by determining ambient temperature of at least a portion of the wireless communication device based on the first and second measured transmit powers and a relationship between the first and second temperature-based biasing conditions. The method continues by compensating transmit power level of the wireless communication device based on the ambient temperature.
