Abstract: A protective tree tube has an elongated hollow body that is made of a biodegradable material, and has holes formed in the wall of the tube. The tube can be filled, at a bottom portion, with drainage material, and on top of the drainage material a planting material can be provided in which the root ball of a tree is placed. Upon placing the protective tree tube with the tree into a planting hole, the protective tree tube ca be buried and thereafter the tree will commence forming new rootage and become established.

Abstract: The present invention provides methods for treating a stiffened joint in a subject that comprise administering relaxin, e.g., a PEGylated relaxin-2, to the subject. The relaxin may be administered intra-articularly as a sustained release formulation. The present invention also provides sustained release formulations in the form of a hydrogel for administering polypeptides that are covalently attached to a polymer, e.g., PEG.

Abstract: Systems and methods are described for using a single wideband pilot signal to reduce a timing misalignment between receivers in a multiple-input multiple-output (MIMO) radio system. The multiple generators of the MIMO radio system may be aligned using a second wideband pilot signal subsequent to performing the receiver alignment. The calibration kit of the MIMO radio system may be aligned using a third wideband pilot signal prior to performing the receiver alignment. Alignment may be achieved to subsample precision by determining time delays from the rate of change of the phase shift of the wideband pilot signals.

Abstract: A pipe restraint assembly includes a restraint body configured to be removably attached to a portion of pipe. The portion of pipe is associated with a postulated pipe failure associated with a release of high pressure fluid. A plurality of apertures penetrate through the restraint body and are positioned proximate to a location of the postulated pipe failure. The apertures are configured to provide a number of passageways for the fluid to exit from the location of the postulated pipe failure and to be released outside of the restraint body. One or more restraint devices maintain the position of the apertures relative to the location of the postulated pipe failure.

Abstract: A portable structure including a base, a first wall panel and a second wall panel. The base includes a first post and a second post. The first wall panel includes a first outer corner extrusion and a second outer corner extrusion, the first outer corner extrusion adapted to partially enclose the first post and the second outer corner extrusion adapted to partially enclose the second post. The second wall panel includes a first inner corner extrusion adapted to fully enclose the first post when used in combination with the first outer corner extrusion.

Abstract: The apparatus, systems and methods disclosed herein generally relate to the surgical repair or alteration of bone. More particularly, certain of the disclosed apparatus, systems and methods of the present disclosure relate to the use of a directionally-reinforced composite material to emulate anisotropic structural characteristics of an original anatomic trabecular structure. The directionally-reinforced composite material may generally include a scaffold set in a composite matrix, wherein the scaffold determines the anisotropic structural characteristics of the materials. In some of the embodiments, a scaffold may include at least a first plurality of struts which are generally aligned in a first direction and a second plurality of struts aligned in a second direction.

Abstract: In one general aspect, the invention features an illumination source that comprises a housing and a plurality of LED illumination elements that are mounted proximate each other in a central cluster with respect to the housing and leaving a peripheral space around the cluster, with the peripheral space being significantly larger than a separation between the LED illumination elements in the cluster. A transparent housing cover is mounted with respect to the housing in front of an axis of illumination of the LED illumination elements. A tinted transparent housing cover and/or a smoothing LED can also be employed.

Abstract: In one general aspect, an LED-based illumination source is disclosed that includes a screw-in household base with an outer thread centered about an insertion axis. A directional-type illumination housing is mechanically connected to the base and has a round light delivery end centered around the insertion axis and has a diameter that is larger than the base. One or more LED illumination elements occupy a portion of the round light delivery end of the directional-type illumination housing and each has an optical axis at least generally parallel with the insertion axis and face away from the base. One or more at least generally coplanar lenses have at least generally parallel optical axes each being aligned with one of the elements and being positioned opposite from the base with respect to the elements.
