Abstract: An example equipment structure includes an outer wall for deployment at least partially below the surface of the ground. An inner casing is provided within the outer wall and forms an interstitial space between the inner casing and the outer wall. The inner casing provides a protective barrier for an equipment cavity formed within the inner casing. A lid covers the equipment cavity for electronics equipment. A riser column is mounted in the equipment cavity formed within the inner casing. The riser column has a backplane to mount the electronics equipment thereto. The riser column is configured to move between a first lowered position in the equipment cavity formed within the inner casing, and a second raised position for access to the electronics equipment mounted to the backplane.

Abstract: A laundry dryer control method including: setting the dryer to a default drying operation; performing the default drying operation when a user selects the default setting and does not select a dry boost setting; and performing a non-default drying operation when a user selects the default setting and does select a dry boost setting. In default operation, the dryer operates the drum and fan, and operates supplemental drying mechanism according to a predetermined schedule of “on” cycles and “off” cycles. If dry boost is selected, or if another non-default cycle is selected, the dryer operates the drum, fan and supplemental drying mechanism using a temperature feedback control loop, and operates until the laundry reaches a first dryness threshold.

Abstract: A trailer system having an adaptable trailer-deck assembly which incorporates rails to increase the surface area of attachment points, and a plurality of sleeve members. This modular design allows for a plurality of attachment and insertion points for a variety of accessories for both residential and recreational use. The arrangement of one or more sleeve members may align with similarly-oriented sleeve members on a watercraft for ease of transition between vehicles. The trailer system may be folded into a stowable orientation via a winch mechanism.

Abstract: A watercraft having a frame which incorporates rails and a plurality of sleeve members. The rails may be used to increase modularity of the watercraft and increase the surface area for attachment of accessories and may be comprised of modular aluminum extrusion. The sleeve members may be used to attach a variety of accessories for recreational watercrafting or for fastening the watercraft to a trailer.

Abstract: A laundry dryer control method comprising: setting the dryer to a default drying operation; performing the default drying operation when a user selects the default setting and does not select a dry boost setting; and performing a non-default drying operation when a user selects the default setting and does select a dry boost setting. In default operation, the dryer operates the drum and fan, and operates supplemental drying mechanism according to a predetermined schedule of “on” cycles and “off” cycles. If dry boost is selected, or if another non-default cycle is selected, the dryer operates the drum, fan and supplemental drying mechanism using a temperature feedback control loop, and operates until the laundry reaches a first dryness threshold.

Abstract: A reinforced notched sub-purlin is formed by a top flange, one or more vertical webs, one or more base flanges, one or more notches, and at least one reinforcement. The top flange extends the entire length of the reinforced notched sub-purlin. The vertical web(s) extend from the top flange, and the one or more notches are formed by removing a portion of the vertical web (where only one vertical web is used) or by separating adjacent vertical webs (where a plurality of vertical webs are used). A base flange extends from the vertical web(s) in a direction opposite the direction in which the top flange extends from the vertical web. The at least one reinforcement is provided on the vertical web(s) and provides enhanced stiffness, thus improving ability of the reinforced notched sub-purlin (and a roof or wall panel installed thereon) to resist forces resulting from, for example, wind and snow.
