Latest Patents

One of Joseph Madak's latest patents is the "Magnetorheological fluid damper with multiple annular flow gaps." This improved damper closely approximates ideal performance requirements by providing an increased turn-up ratio and enhancing the linearity of damping force response. The design includes a plurality of concentric annular flow gaps formed between concentrically mounted flux rings positioned on a piston core. By utilizing multiple flow gaps, the damper increases the overall magnetorheological damping effect, creating a higher damping force and an increased turn-up ratio for a given piston size. Alternatively, this design allows for achieving a required damping force with a piston of significantly reduced length, thereby permitting a longer piston stroke. Additionally, the multiple flow gaps enable greater design optimization for controlling damping force linearity.

Another significant patent is the "Device for cooling power electronics." This invention features a heatsink or cold plate that cools power electronic components mounted to its surface with a cooling fluid flowing through it. The cold plate consists of a relatively planar structure with one or more passages directing the cooling fluid. These passages lead to recesses in the surface of the cold plate, enclosed by the power electronic components. This design allows for enhanced heat transfer characteristics by directly impinging the cooling fluid at the lower surfaces of the components, preferably at an acute angle.
