Abstract: A mobile electronic device such as a tablet computer is provided having flexible display panel that deforms in response to the application of pressure thereto. The tactile response of the display panel is affected by underlying structures. A bottom layer, which may be rigid, is positioned beneath, parallel to and spaced away from the flexible display panel. Elastic diaphragms or elastic bodies can be interposed between the display panel and bottom layer. A guidance matrix, which may be rigid, can be further interposed between the display panel and bottom layer, such that pressure applied to the display panel results in localized downward deformation in the area of a guidance matrix cavity. The elastic diaphragms or elastic bodies may extend into the guidance matrix cavities. These subsurface structures may be utilized to provide variable tactile response corresponding to the locations of keys on a virtual keyboard displayed on the display panel.

Abstract: A heat exchanger includes a first header tank, a second header tank, and a core. The core is positioned between the first header tank and the second header tank. The core includes a plurality of tubes, a set of cooling fins and a plurality of channels. Each tube of the plurality of tubes provides fluid communication between the first header tank and the second header tank. The set of cooling fins are located between the heat exchange tubes of the plurality of tubes to increase a heat exchange area. The plurality of channels is defined by the plurality of tubes and the set of cooling fins. The channels of the plurality of channels are operative for directing a flow of air through the core such that a flow of air enters a front face of the core in a first direction and is generally directed toward a plane.

Abstract: A heat exchanger includes at least two tanks containing a medium to be temperature treated and a plurality of heat exchange tubes extending between the at least two tanks. The heat exchange tubes have exterior surface areas at least partially defining a heat exchange area. A set of cooling fins is located between the heat exchange tubes of the plurality of heat exchange tubes to increase the heat exchange area. The fins are configured to define a plurality of non-straight line paths for the flow of air across the heat exchanger. The non-straight line paths force the flow of air across the heat exchange to change direction and cause impingement of the air onto the fins and tubes as well as turbulence for increasing heat transfer performance.

Abstract: A frame subassembly for a vehicle is provided that includes a one-piece hydro-formed upper side beam and may also include a one-piece hydro-formed lower side beam. The side beams extend from the front or grill area of the vehicle to the rear portion of the vehicle. The side beams are interconnected by A, B and C pillars. The beams are welded to each other through access openings in the beams and in and the pillars. The pillars are attached to the beams by welding through access holes.
