Abstract: A monitor system has at least first and second child units that can each monitor audio at a different location and can each transmit signals representative of the audio monitored. A parent unit can receive the signals from the first and second child units. In one aspect, the parent unit can have at least one multi-color notification light that can be illuminated in a first color when receiving the audio monitored by the first child unit and a second color different from the first color when receiving the audio monitored by the second child unit. In another aspect, the parent unit can emit an audible notification representing the audio monitored by each of the child units. In this aspect, a volume control is in communication with the parent unit and can be operated to adjust a volume level of the emitted audible notification for each of the child units independent of the other child units.
Abstract: Disclosed herein are digital systems and methods for use with a ramped clock signal. The digital system includes an input element having a data input to receive a data signal, a control input to receive a control signal, and a dynamic node to be driven by the ramped clock signal. The digital system further includes a static memory element having an input at the dynamic node and is configured to reside in an operational state in accordance with the data signal and the ramped clock signal. The input element further includes a switch coupled to the control input to condition updating of the operational state based on the control signal without decoupling the ramped clock signal from the dynamic node. In this way, distribution and delivery of the ramped clock signal to the digital system is continued to facilitate recovery of clock signal energy from the digital system.

Abstract: A playard is movable between an open arrangement and a folded arrangement. The playard includes a plurality of legs, a plurality of pivot joints connected to the plurality of legs, and a plurality of slider joints engaging the plurality of legs. A plurality of cross members are arranged in pairs extending between the legs, and at least one latch mechanism is operable in a latched condition to maintain a predetermined gap along a leg between one of the slider joints and one of the pivot joints to prevent movement of the playard toward the folded arrangement. A plurality of top rail segments extend between the legs to define an upper periphery of the playard.

Abstract: A stroller is provided having a stroller frame supported by front and rear wheels. The frame includes a latch assembly that is movable between a locked and an unlocked position. When in the locked position, the latch assembly prevents the frame from being folded. When in the unlocked position, the latch assembly allows the frame to be folded. A cup holder is supported by the frame that can move between an extended and a retracted position. The cup holder automatically moves to the retracted position when the stroller is folded.
Abstract: A foldable stroller has a frame assembly reconfigurable between an in-use configuration and a folded configuration. The frame assembly has a left and a right frame side and each frame side includes an elongate bottom part having a front end and a back end. Each bottom part is oriented extending generally from a front to a back of the frame assembly. A fold latch is on the frame assembly and has two latch parts pivotally coupled to one another. A push arm has a lower end connected to one of the latch parts and extends upward and rearward to a handle. A front leg has a lower end pivotally coupled to a front end of the bottom part and extends upward and rearward to an upper end connected to the other of the latch parts. A support strut has an upper end pivotally coupled to the fold latch at a pivot axis and has a lower end pivotally coupled to the bottom part forward of the back end at a pivot connection. The pivot connection of the support strut in one example is positioned further forward than the pivot axis.

Abstract: A stroller has a frame structure with spaced apart sides and is collapsible from an in-use arrangement to a compact collapsed arrangement. The stroller has a seat supported by the frame structure and has a tray assembly with a front. The tray assembly is supported between the sides of the frame structure and is spaced from the seat when the frame structure is in the in-use arrangement. A foot is provided as part of the tray assembly. The foot is in an extended position projecting outward relative to the front of the tray assembly when the frame structure is in the collapsed arrangement. The foot is in a stored position when the frame structure is in the in-use arrangement.

Abstract: A stroller has a stroller frame with a child seat positioned on the stroller frame. The stroller further includes a child barrier that can be coupled to the stroller frame forward of a seat bight of the child seat. The child barrier also includes a cup holder with a central longitudinal axis. When the child barrier moves relative to the stroller frame, the cup holder pivots about the central longitudinal axis.

Abstract: A playard includes a frame structure movable between an open arrangement and a folded arrangement. The frame structure includes a plurality of pivot joints arranged in an upper set and a lower set, each pivot joint in the upper set being positioned over a corresponding pivot joint in the lower set, and a plurality of cross members connected at respective slants to the upper and lower sets of pivot joints. The playard further includes a plurality of top rails, each top rail being attached to adjacent pivot joints in the upper set. The frame structure lacks legs to support the upper set of pivot joints at an elevation above the lower set of pivot joints. The elevation decreases as the respective slants of the cross members change to move the frame structure from the folded arrangement to the open arrangement until the top rails are under tension.
