Embodiments of the invention provide a composition for shielding radiation, including 100 parts by weight of a first resin including one or more selected from the group consisting of a polyurethane resin, a polysiloxane resin, a silicone resin; a fluorine resin, an acrylic resin, and an alkyd resin; 5 to 30 parts by weight of a second resin including one or more selected from the group consisting of polyvinyl alcohol (PVA), medium-density polyethylene (MDP E), high-density polyethylene (HDPE), and low-density polyethylene (LDPE); 5 to 30 parts by weight of a polyether ether ketone (PEEK) resin powder; 5 to 80 parts by weight of a metal powder; 1 to 70 parts by weight of a metal oxide powder; 1 to 50 parts by weight of paraffin; 5 to 15 parts by weight of a boron compound; and 10 to 50 parts by weight of a carbon powder. Accordingly, a fiber complex, protective clothing, and the like including the composition for shielding radiation of the present invention includes a PEEK resin without use of lead, and thus, may shield even neutron rays as well as radiation, such as alpha rays, beta rays, proton rays, gamma rays, and X-rays.

Solid-state additive manufacturing methods for compounding conductive plastic compositions, fabrication of conductive plastic parts and conductive coatings, and plastic recycling are disclosed. Electrically conductive or thermally conductive plastic compositions are compounded and subsequently printed with the solid-state additive manufacturing system. The solid-state fabricated compositions, parts and coatings can also be manufactured to be both thermally and electrically conductive. Solid-state plastic waste recycling methods are also disclosed where various plastic waste materials and shapes are solid-state processed. The plastic waste can be mixed with virgin plastic material or mixed with other types of materials such as metals, ceramics or their combination. The waste plastic feedstock is reinforced with different types of reinforcing particles or fibers, or various additives are added for improving properties of the final deposits.

The invention relates to a radar device (1) for a motor vehicle, having a radar apparatus (2) for emitting and receiving electromagnetic waves (4) and having at least one absorption element (9, 100), which is formed from an absorption material which absorbs the electromagnetic waves (4), wherein the at least one absorption element (9, 100) is embodied as an element which is separate from a housing (3) of the radar apparatus (2) and is arranged outside the housing (3), in particular on the housing (3).

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a proximal member having a proximal end, a distal end, and a proximal diameter. The guide extension catheter may additionally include a collar member attached to the distal end of the proximal member, the collar member comprising a base portion and one or more ribs connected to the base portion and extending distally away from the base portion. In still some additional embodiments, the guide extension catheter may further include a distal sheath member attached to the collar member, the distal sheath member having a distal diameter larger than the proximal diameter.

A connector including an electrically conductive shell with a generally tubular shell body, a body insert-molded inside the shell body, a terminal entirely disposed inside the shell body, and a cable. The shell body extends in a first direction. The body is entirely housed inside the shell body, is exposed from inside the shell body to one side in the first direction, and includes a housing hole extending through the body in the first direction. An intermediate portion of the terminal is at least partly retained in the housing hole. A rear portion of the terminal is disposed in the housing hole, or alternatively protrudes from the housing hole to the other side in the first direction. The cable is partly received inside the shell body from the other side in the first direction and connected to the rear portion of the terminal inside the shell body.

Various systems, devices, and methods for insulated containers with a drawer are provided. In general, an insulated container, such as a portable cooler, includes a drawer. The insulated container includes a main chamber and includes a drawer chamber that is separate from the main chamber and is configured to movably receive the drawer therein. The main chamber is configured to hold a cooling agent that is configured to cool any items in the main chamber and also any items in the drawer. The insulated container can be manufactured using injection molding.
