Abstract: An HVAC case having an airflow junction. A mount is at the airflow junction and is configured to individually mount a door and an airflow blocker at the airflow junction. The door is mounted at the mount of the airflow junction to configure the HVAC case for use with HVAC systems configured for airflow through the airflow junction. The airflow blocker is mounted at the mount of the airflow junction to configure the HVAC case for use with HVAC systems not configured for airflow through the airflow junction.

Abstract: An airflow door for a heating, ventilation, and air conditioning (HVAC) system. The airflow door has a first material and a second material. The first material and the second material are temperature responsive materials that change shape at different temperatures such that at a first temperature the first material and the second material are shaped to provide the airflow door with a first configuration, and at a second temperature the first material and the second material are shaped to provide the airflow door with a second configuration that is different from the first configuration.

Abstract: An airflow baffle for controlling airflow through a heating, ventilation, and air conditioning (HVAC) system. The airflow baffle includes a main body, an upstream side of the main body, and a downstream side of the main body. A plurality of holes are defined by the main body, and extend through the main body between the upstream side and the downstream side. The plurality of holes include holes of various different diameters spaced apart at various different intervals to provide uniform airflow through the baffle.

Abstract: A vehicle heating, ventilation, and air cooling (HVAC) system that includes a module, an evaporator, and a heater core; the module defines a defrost outlet, a side window outlet, a front face outlet, and a front foot outlet. The evaporator and heater core are both housed within the module. The defrost outlet being open and closed by a defrost door, the side window outlets being open and closed by a plurality of demist doors. The defrost door and demist doors share a common shaft, a torsion spring around the shaft allows the defrost door to remain offset from the demist doors.

Abstract: A composition for damping mechanical motions, such as for damping of mechanical impacts or oscillations can include at least one collagen as well as at least one carrier matrix for the at least one collagen. The carrier matrix contains a formable material. The composition also can include at least one liquid having or containing polar molecules. The carrier matrix, the at least one collagen and the liquid form a mixture (or batch). A method for manufacturing a material for use in damping mechanism motions includes preparing an essentially non-cross-linked, liquid elastomer parent substance as well as providing a liquid collagen parent substance that contains at least one collagen and at least one liquid with polar molecules. The method also includes generating a mixture from the elastomer parent substance and the collagen parent substance as well as cross-linking molecules of the elastomer parent substance in the generated mixture.

Abstract: A spring mattress including a plurality of helical springs formed of rattan tubes and extending between the top and the bottom of the mattress sheath, with the helical springs forming a plurality of parallel, spaced from each other rows of helical springs, and stiffening grids provided at opposite ends of the helical springs for retaining the helical springs in their predetermined positions.

Abstract: An energy-absorbing damping device comprises a basic body which delimits a liquid-filled chamber, the basic body being provided with channels opening onto the outside of the basic body, the channels ensuring communication with a medium which deforms elastically under the pressure of the liquid. To enhance the cost-effectiveness of the damping device, the channels are designed as narrow, flow-restricting channels and the elastically deformable medium is an elastically extensible diaphragm sealed around it periphery and covering the external openings of the flow-restricting channels. The energy of an impact or a blow is absorbed by the liquid being forced through the narrow flow-restricting channels and by extension of the elastic diaphragm.

Abstract: There is a sports shoe with a sole (4) and an inflating device which is arranged under a convex part of the foot (3) and delimits a compression chamber (16) with a chamber body (1) as well as a chamber roof (14), the compression chamber having an inlet opening (17) and an outlet opening (18). It is desirable to improve the effect of the inflating device by minimizing the clearance space in the compression chamber. This is accomplished by forming the compression chamber (16) as a semi-lentil-shaped (dished) bowl which is conformed to fit the convex contour of the region of the foot (3) loading it and by having the inlet opening (17) as well as the outlet opening (18) arranged in the central area of the chamber (16). Since, on compression, the chamber cover will hug the bottom of the compression chamber, it is possible to produce a positive pressure commensurate with the down-stepping force applied.
