Abstract:
An aircraft component includes a first segment having a first leading edge surface that extends to a first end of the first segment. The aircraft component also includes a second segment having a second leading edge surface that extends to a second end of the second segment. The second end is substantially adjacent to the first end of the first segment, and is connected to the first end. The first leading edge surface includes electrical resistance heating that extends to the first end of the first segment. In addition, the second leading edge surface includes electrical resistance heating that extends to the second end of the second segment. The electrical resistance heating is capable of providing ice protection heating immediately on either side of a juncture between the connected first and second ends.
Abstract:
A trailer comprises a trailer body having a side portion. A trailer cover is coupled to the trailer body and is movable between a first position and a second position relative to the trailer body. The trailer cover in the first position is sufficiently rigid to support a recreational vehicle above the side portion of the trailer body. The trailer cover, when in the second position, forms at least a portion of a roof and is spaced from the trailer body a sufficient distance to at least partially define a habitation space below the trailer cover.
Abstract:
A string-replacement assembly may be installed within an inner cavity of a body of a guitar. The assembly includes a plurality of cartridges each configured to contain a supply of replacement string therein, corresponding to a particular gauge of string for the guitar. Each supply of replacement string is rotatably mounted within a cartridge. A free end of each supply of the replacement string can be threaded through an exit opening in the body of the guitar for installation on a topside of the guitar. When string breaks or needs to be replaced on the topside of the guitar, a portion of the supply of the replacement string may be readily advanced from a corresponding cartridge to a desired length, and installed in a playing position on the topside of the guitar, to replace a removed portion (associated with the breakage or replacement) of the string.
Abstract:
A system for conducting a survey to obtain real-time survey evidence. It has a host server (12), a questions database (24) associated with the host server (12), and comprising records representing a survey, each record comprising a question with associated possible answers. A data acquisition device (14) to receive survey questions with associated possible answers and operable by an interviewee to select a response from the possible responses for a question and transmit the response for the question to the host server (12). A responses database (26) associated with the host server to store responses to the questions received by the host server (12) in which the responses are associated with the survey.
Abstract:
An inclined lift device for transporting an individual passenger includes a rail, a carriage adapted for being movable along the rail, a drive mechanism coupled to the carriage for moving the carriage along the rail, and a support secured to the carriage for supporting the individual passenger. The rail has at least one retaining surface and a guide surface. The carriage includes a housing pivotally coupled to the rail about an axis spaced from the guide surface, a retaining mechanism pivotally coupled to the housing about the axis and a follower coupled to the housing and spaced from the axis by a predetermined distance. The retaining mechanism engages said at least one retaining surface of the rail to retain the carriage relative to the rail during movement of the carriage along the rail. The follower engages the guide surface to pivot the carriage about the axis based upon a distance between the guide surface and the axis.
