Abstract: Aircraft wings, aircraft, and related methods. Aircraft wings include a spoiler constructed substantially of a monolithic structural body with an upper side that defines a portion of an airfoil surface of an aircraft wing. The monolithic structural body further includes a lower side, opposite the upper side, that includes a plurality of stiffening ribs that define a plurality of open voids. Methods of constructing a spoiler for an aircraft wing include forming a monolithic structural body of the spoiler.

Abstract: An impairment detection device includes a body and a housing removably secured to the body that together resemble a beverage container. A breath analyzer is located within the housing or body and includes a chemical sensor that is configured to detect a chemical impairment level of a user, such as resulting from the use of drugs and/or alcohol. The housing is configured to be removably secured to the body to enable a user to quickly attach and remove the housing from the body. The combination of the housing and body provides a disguise for the impairment detection device because it resembles an actual beverage container. A mouthpiece extends from the housing and is in communication with the chemical sensor for receiving a user breath sample. The housing includes a user interface that is operably associated with the breath analyzer.

Abstract: A concealment apparatus for an ignition interlock device includes a container defining a cavity with an open upper end, and a lid covering the open upper end. The cavity is configured to receive and conceal an ignition interlock device, such as a handheld ignition interlock device. The apparatus may be configured to resemble a beverage container.

Abstract: A concealment apparatus for ignition interlock devices includes a container that has a top, a bottom, and at least one side wall separating the top and the bottom. The at least one sidewall includes a screen opening for viewing at least a screen of an ignition interlock device. The container can resemble a beverage container, such as a mug, a tumbler, a can, a sports bottle, or a thermos. An ignition interlock concealment system includes a concealment apparatus and an ignition interlock device contained therein.

Abstract: The present invention relates to a wireless personal communications system (WPCS) having several features embodied in several forms. In one embodiment, the, WPCS includes at least one RP, a first SU in communication with the RP, and a second SU in communication with the first SU through the RP without involving the RPC in the manner contemplated by the specification. The RP may preferably include a channel switching unit for connecting the first SU with the second SU without using any tariff lines to or from an RPC. Such an RP may be used as a component in a wireless PBX or Centrex system including ISDN based systems. Another preferred embodiment provides for a walkie-talkie option where the first SU communicates directly with the second SU, preferably over an unlicensed frequency. In another preferred embodiment, a plurality of SUs in communication with an RP may be accessed individually using a single dialed number.
