  • Patent number: 8807630
    Abstract: A cowling assembly (10) is installed about the radiator (R) of a vehicle (V). A frame (12) fits about the radiator and defines an opening through which air can flow into the radiator. The frame has a contour that allows air flow smoothly about the frame. A cover including a panel (18) or a coiled sheet (118) is movable through the frame to cover the opening. A motor (50) operated by a controller (80) moves the panels or sheets to expose a portion of the opening and allow air to flow into the radiator. The frame and the panel or sheet facilitate smoother air flow over and about the front of the vehicle thereby reducing the amount of drag on it while still allowing air flow into the radiator.

  • Patent number: 8802469
    Abstract: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.

  • Publication number: 20140207005
    Abstract: There is taught herein a real-time, lumped parameter cardiovascular dynamics model that uses features extracted from online electrocardiogram (ECG) signal recordings to generate certain surrogate hemodynamic signals. The derived signals can be used to real time animate a 3-D heart model. The model represents the coupled dynamics of the heart chambers, valves, and pulmonary and systemic blood circulation loops in the form of nonlinear differential equations. The features extracted from ECG signals can be used to estimate the timings and amplitudes of the atrioventricular activation input functions as well as other model parameters that capture the effect of cardiac morphological and physiological characteristics. The results indicate the potential of a virtual instrument that uses the model-derived signals for clinical diagnosis in lieu of expensive instrumentation.
