Abstract: A shielded electrical connector having an elongated annular housing composed of an electrically insulative material molded so as to form an elongated structure for the connector and at least a portion of a grasp for a user of said connector. The housing defines outside and inside surfaces and front and rear ends for said connector. A contact holding portion composed of an electrically insulative material is positioned inside said annular housing and includes a plurality of electrically conductive signal contacts positioned therein so as to be completely surrounded by, yet spaced a distance away from, the inside surface of the housing. An elongated annular electrically conductive shield having inner and outer sides is insert molded with the housing so as to be disposed between its outside and inside surfaces.

Abstract: A flexible multi-parameter conductor cable having coaxially symmetric elongated zones for signal carrying conductor placement therein, comprising an electrically conductive inner shield defining an electrically shielded inner longitudinal zone symmetrically disposed along and defining a center of said cable for containing at least one of a first type of signal carrying conductor, and an electrically conductive outer shield spaced a given distance symmetrically around said inner shield so as to define an electrically shielded outer longitudinal zone symmetrically disposed about said inner longitudinal zone for containing a plurality of at least a second type of signal carrying insulated conductor arranged in a single layer adjacent one another in said second longitudinal zone, said second type of conductor having an electrically conductive outer jacket in electrical contact with at least said outer shield.

Abstract: The control unit of an automatic blood pressure monitor has a central chimney-shaped heat sink which is open at the top and the bottom. Air rising through the chimney dissipates heat generated during operation of the device. Additionally, in the event that liquid is accidently spilled from e.g. a bag of saline solution, it is directed downwardly through the chimney via a funnel.
