摘要:
In a phase-locked loop (PLL) calibration system and method, the PLL input reference clock is phase-modulated, the resulting PLL output modulation is measured, and PLL calibration signals, such as a PLL proportional path adjustment signal and a PLL integral path adjustment signal, are derived from the measured PLL output modulation.

An active termination circuit for a differential receiver includes a first receiver element configured to receive a first component of a differential signal, a second receiver element configured to receive a second component of a differential signal, a common mode measurement element configured to receive the differential signal and generate a transmit common mode signal (Vcm) representing an average value of the differential signal, and a receiver (RX) common mode signal node. The termination circuit also comprises an active element configured to receive the transmit common mode signal (Vcm) and provide an output to the receiver common mode signal node, the output configured to drive the value of the signal at the receiver common mode signal node to the value of the transmit common mode signal (Vcm), and a capacitive element coupled to the receiver common mode signal node in parallel with the active element.

A pet enclosure includes a cover and a collapsible support frame. The cover includes a bottom panel, a top panel opposite the bottom panel, and a plurality of side panels extending between the bottom panel and the top panel to define an interior space of the cover, wherein an aperture is defined in the cover for accessing the interior space. The collapsible support frame is configured for insertion into the interior space of the cover via the aperture, and the support frame includes a floor arrangement, a first truss hingedly connected to the floor arrangement, and a second truss hingedly connected to the floor arrangement opposite the first truss. The first truss and the second truss are movable relative to one another within the interior space of the cover between a collapsed configuration of the support frame and an uncollapsed configuration of the support frame.
摘要:
A pet enclosure includes a cover and a support frame. The cover includes a bottom panel, a top panel opposite the bottom panel, and a plurality of side panels extending between the bottom panel and the top panel to define an interior space of the cover. An aperture is defined in at least one of the top panel and one of the plurality of side panels for accessing the interior space. The support frame is pivotable between a collapsed configuration and an upright configuration and is insertable into the interior space of the cover through the aperture in the collapsed configuration of the support frame. The support frame is also pivotable from the collapsed configuration to the upright configuration while disposed within the interior space of the cover.

A collapsible pet enclosure is provided. The enclosure includes a pliable cover supported by a rigid, but foldable, frame. The cover includes an opening in a top panel such that the enclosure is top loading. The cover is completely removable from the frame so that it can be machine washed. The frame is of one-piece jointed construction so that it is collapsible for easy transportation or storage. Because all frame components are jointedly attached to one another, the frame does not include any loose components that are easily lost. The enclosure is quick and easy to set up and collapse.

A transfer decal retail product unit includes a transfer decal assembly, which can optionally be mounted on a display card. The assembly includes a liner comprising a material that contrasts visually with a graphic material releasably mounted thereon. An optional clear, transparent mask is releasably mounted on the graphic material and is adapted for removal after installation. The visual contrast between the liner and the graphic material facilitates point-of-purchase sales by attracting customers.
