Abstract: A medical device for infusing medical substances has activation buttons accessible on the exterior of the device housing. Activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to the user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether activation is intended and valid. These time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.

Abstract: An improvement to foldable headrests remote actuators by providing a tube mounted spring compensator to facilitate movement between a stowage position and an operating position. The spring compensator is inserted concentrically within the hollow tubes that support the adjustable headrests to boost or compensate for the lack of force routinely experienced under cold weather use or aging of materials. The spring compensator is positioned inside the headrest support tube to help pull the cable up through the seat when the seat and headrest are returned from a stowage position to a passenger seating position. The spring compensator inside the headrest support tube allows the use of a smaller torsion spring in the headrest and reduces the stress on the components in the mechanism.

Abstract: A micropump according to the invention uses axially oriented pistons to define a pump volume. Translating the pistons axially with respect to each other within a pump housing draws a metered amount of fluid into the pump volume from a reservoir port for delivery to a cannula port when the space is collapsed. Radially situated seals on the pistons cooperate with the axial movement to close off and open the cannula port and the reservoir port respectively at different positions of the piston stroke.
