Abstract: A protective case for an electronic device having an antenna includes a first case member and a second case member. The first case member includes at least two metallic case portions joined to each other by at least one electrical insulator segment that electrically isolates the at least two metallic case portions from each other to reduce electromagnetic interference between the first case member and the antenna of the electronic device. The second case member that attaches to the first case member to form an enclosure that at least partially encloses the electronic device when the electronic device is installed in the protective case.

Abstract: A metallic protective case for an electronic device having an antenna structure includes a first metallic case element and a second metallic case element. The first metallic case element includes at least two metallic case portions joined to each other by a first set of electrical insulators and also includes a lip. The second metallic case element is hingedly attached to the first metallic case element to form a hinged enclosure having an open position and a closed position. The hinged enclosure is adapted to receive the electronic device when in the open position and at least partially enclose the electronic device when in the closed position. The second metallic case element includes at least two metallic case portions joined to each other by a second set of electrical insulators, a first latch portion, and a second latch portion.

Abstract: At least one embodiment of the inventive technology may be an item support apparatus (1) that comprises at least two fee (4); a base (5) from which said feet extend at a first retention element (6); at least two risers (7) retained to the base by a second retention element (8); and at least one arm (9) retained to each riser by an arm retainer (10). Disclosed is a novel, efficient yet strong item support stand that may be used to support an item such as a musical instrument (a keyboard, as but one example) and that may be collapsible and/or adjustable in certain embodiments.

Abstract: In a multiblower system for cooling electronic components, each blower has a backflow preventor. The backflow preventor has two pieces of flexible material and a screen attached to the intake side of the blower assembly. Each of the pieces of flexible material is scored through to form a petaled opening through which air may pass. The scores on one of the pieces of flexible material are out of alignment with the scores on the other piece when assembled together in the blower assembly. When the blower is running, the petals in the pieces of flexible material open to allow air to pass through the blower assembly. When the blower is stopped, the petals are closed against the screen due to the pressure differential between the inside of the enclosure and the outside of the enclosure caused by the effect of the draw of the other blowers in the system.
