The present application provides a handheld wireless communication device. The handheld wireless communication device includes a two part housing having an upper housing and a lower housing, the upper housing and the lower housing being rotatably coupled together via a hinge. The upper housing and the lower housing through a relative movement via the hinge can transition between an opened position and a closed position. The lower housing has a first conductor including one or more tuned structures and has a second conductor including one or more tuned structures, where each of the tuned structures of the first conductor and the second conductor are adapted for at least one of transmitting or receiving electromagnetic energy having a respective predefined range of frequencies in support of wireless communications. The first conductor and the second conductor in a spaced apart fashion relative to each other are located proximate a first side edge of the lower housing, where the first side edge is opposite a second side edge of the lower housing, where the second side edge of the lower housing is the side edge of the lower housing, which is most directly coupled to the upper housing via the hinge.

Foldable wireless electronic devices that communicate wirelessly are provided that can attenuate the cavity modes created when the devices are folded. The electronic devices may utilize prescribed housing dimensions, ohmic contacts, and capacitive coupling to attenuate the cavity modes. There may be minimal impact on the industrial design of the devices. The radiation efficiency and VSWR of the antennas of the electronic devices may not be degraded. Also, the frequency of the cavity modes may be controlled such that the cavity modes are resonated out of frequencies of interest, and the severity and occurrence of RF energy absorption may be attenuated or eliminated. Users of the foldable wireless electronic devices may have increased satisfaction as the devices may perform better while still having desirable aesthetics and appearance.

The present inventiondiscloses a portable, modular skate rail comprising a plurality of square or tubular interlocking rail membersthat may be assembled to provide grind rails of various lengths and elevations. Each rail memberhas at least one hinged leg supportwith a hinged footplatethat allows the leg support and footplate to be folded in a substantially parallel relation to the rail member to save space during transport and storage. Additionally provided are bracketswhereby two railscan be fastened together with one rail having a handlefurnishing means for porting the present inventionas an integral assembly. The railsof the present inventionmay also be adapted to provide an angled rail relative to the ground
