Abstract: A system for near-surface geophysical subsurface imaging for detecting and characterizing subsurface heterogeneities comprises an instrument that outputs probing electromagnetic signals through a ground surface that interact and are affected by scattered signals of acoustic waves that travel through the ground surface and further senses vibrational modes of a subsurface below the ground surface; an imaging device that dynamically generates a time sequence of images of properties of the acoustic waves and maps elastic wave fields of the acoustic waves; and a processor that analyzes dynamic multi-wave data of the images to quantify spatial variations in the mechanical and viscoelastic properties of the subsurface.

Abstract: An adjustable bouncing frame for a child support device including a support frame coupled between a base portion and a child seat platform of the child support device. The support frame is configured to support the child seat platform a distance above the base portion which rests on a support surface. The adjustable bouncing frame generally includes at least one support member that is slidingly coupled to the child support device at a first end. Lateral movement of the first end of the support member can adjust the height of the child seat platform relative to the base. The frame can also include a resilient member that allows for reciprocal lateral motion of the first end of the support member which results in an up-and-down bouncing motion of the child seat platform.

Abstract: A child support device is provided with a height that is easily adjustable. The child support device includes a seat assembly suspended from at least one upright frame member extending above the seat assembly by at least one support member. The upright frame member includes a cap through which the support member is threaded. The height of the seat assembly is vertically adjustable by repositioning engagement of the support member with the at least one upright frame member.

Abstract: A compact jumper for an infant or young child. The compact jumper includes a support frame, at least one resilient member, and a child-receiving apparatus. The support frame is configured for resting on a support surface and the at least one resilient member is coupled to a portion of the support frame. The child-receiving apparatus is supported by the at least one resilient member, with a collar mounting the resilient member to the child-receiving apparatus, and is guided by a portion of the support frame. The child-receiving apparatus is movable with respect to the support surface as the child moves and jumps.

Abstract: A convertible children's walker device includes a seated walker portion and a standing walker portion. The standing walker portion is detachably mounted to the seated walker portion in a first seated-support mode wherein the standing walker portion is used in combination with the seated walker portion, and the standing walker portion is detached from the seated walker portion in a standing-support mode of use independent of the seated walker portion.
