Fire-retardant composites, methods of making fire-retardant composites, and use thereof are described. A fire-retardant composite can include at least two fire-retardant laminates, and a porous thermoplastic core material disposed between the at least two fire-retardant laminates. Each laminate can have one or more ply, each of the plies can include a plurality of fibers in a thermoplastic polymer matrix that includes a fire-retardant composition. The fire-retardant composite meets European fire-retardant standards for rail transportation.

Prefabricated insulated roof assemblies, methods for manufacturing such assemblies, and use of these roof assemblies in a building are described. The assemblies include a sheathing panel comprising an inset solar panel, I-joists, and a rigid foam insulation board positioned in a cavity formed by the sheathing panel and the I-joists.

The present invention relates to a double glazed window of a polycarbonate layer and, specifically, to a double glazed window of a polycarbonate layer, comprising an outer glass layer and an inner polycarbonate layer so as to have improved heat insulation and earthquake resistance. The double glazed window of a polycarbonate layer comprises: a glass layer forming an outer layer; a polycarbonate layer forming an inner layer; a vacuum layer (VL) formed between the glass layer and the polycarbonate layer; and sealing means for sealing the VL while coupling the glass layer and the polycarbonate layer.

A vehicle roof glass element having an exterior glass pane and a transparent insulating layer foamed on the inside onto the glass pane has an externally circumferential rim the runner points and the ventilation points of which are provided on the inside of the glass pane. Furthermore, a method and a tool for manufacturing a vehicle roof glass element are described.

A backpack is disclosed for a personal transport vehicle including, in some embodiments, a back piece including a molded front panel, a securing device, a padded back panel, and a shoulder strap system. The molded front panel includes at least two ridges configured for placement of at least a portion of a body of the personal transport vehicle between the ridges. The securing device, which is attached to a first ridge of the ridges, is configured to cross over the molded front panel to a second ridge of the ridges to secure the body of the personal transport vehicle between the ridges when present. The padded back panel is configured to rest against a backpack wearer's back. The shoulder strap system includes a pair of shoulder straps extending from a top portion of the back piece, across the back panel, and to a medial portion of the back panel.

A personal transport system is provided including, in an embodiment, an electrically powered vehicle, a companion remote control, and a companion mobile phone application. The vehicle includes an operator-supporting deck, one or more deck-mounted trucks, one or more axle-mounted wheels on each of the one or more trucks, one or more batteries, and a deck lighting system. The one or more batteries power a motor configured to drive the wheels by way of a pulley system, at least one battery of which is disposed under a battery enclosure. The battery enclosure has a first light indicator system, and the companion remote control has a second light indicator system, each of which is configured for communicating with the operator. The deck lighting system includes a light strip of light-emitting diodes disposed in a groove of the deck configured to change state to communicate with the operator or others sharing a road.

An energy efficient window includes a plate of glass having a first side and a second side opposite the first side. A polymer aerogel thermal barrier having a first side and a second side is further provided. One of the first side and the second side of the polymer aerogel thermal barrier is located on one of the first side and the second side of the plate glass.

A stack assembly including a glass element having a thickness of less than or equal to 200 microns, and a first layer supporting the glass element. The glass element having a first pen drop height value when directly adjacent on a solid aluminum stage. The first layer having a stiffness of from 910.sup.5 N/m to 2.010.sup.6 N/m. When the glass element is supported by the first layer on the aluminum stage, the glass element comprises a second pen drop height value, wherein the second pen drop height value is greater than the first pen drop height value.
