Abstract: A headlight warning system for a vehicle includes a logic unit and a warning signal generator. The logic unit receives as inputs a level of ambient light at the vehicle, a position of a headlight switch for headlights of the vehicle, a position of an ignition switch of the vehicle, and a position of doors of the vehicle. The logic unit generates a logic output based on the following detected conditions: the ambient light level is low, the headlight switch is in an off position, the ignition switch is in an on position, and the doors of the vehicle are closed. The warning signal generator generates a warning signal output based on the detected conditions. The warning signal output is to cause a vehicle warning device to generate a warning to alert a driver of the vehicle when the headlights of the vehicle are turned off during nighttime driving.

Abstract: A Z source network includes positive and negative input terminals and a first snubber circuit connected across the positive and negative input terminals. The first snubber circuit is configured to suppress voltage transients across the positive and negative input terminals. The Z source network also includes positive and negative output terminals and a second snubber circuit connected across the positive and negative output terminals. The second snubber circuit is configured to suppress voltage transients across the positive and negative output terminals.

Abstract: A flow balancing device facilitates polymer injection in a horizontal formation in a manner that minimizes shear effects on the injected polymer. Features of the device reduce velocity using a broad circumferentially oriented inlet plenum that leads to a circumferentially oriented path having zig-zag fluid movement characterized by broad passages that define the zig-zag pattern so as to reduce velocity at such transition locations. Because the path is circumferentially oriented there is room for broad transition passages independent of the housing diameter. The broad crescent shaped inlet plenum also reduces inlet velocity, and therefore shear, to preserve the viscosity of the injected polymer. Other materials can be injected or the device can be employed in production service as well as injection. A related method employs the described device for injection.

Abstract: An electrical network configured to suppress voltage transients includes a capacitor and an electrical impedance in parallel with a diode. The capacitor is in series with the parallel connected diode and electrical impedance. The electrical network is configured to suppress voltage transients occurring across the series combination of the capacitor and the parallel connected diode and electrical impedance.

Abstract: The flow control device comprises one or more stacked spiral paths where the shape of an inlet to an end of a spiral has a taper on one or more sides to gradually increase the polymer velocity to eliminate rapid acceleration points as the flow enters the spiral path. The entrance with its taper can be curved to get into the spiral. The spiral can be entered tangentially or radially or axially.

Abstract: A liquid transfer arrangement for applying a printing liquid to a printing surface, for example, in a printing apparatus comprising a liquid transfer roller, a printing cylinder with a peripheral printing plate in surface contact with the transfer roller, and an impression cylinder in peripheral surface contact with the printing cylinder for conveying a printable substrate therebetween. The liquid transfer arrangement comprises an encasement arcuately surrounding a substantial circumferential portion of the transfer roller surface to define a substantially uniform constricted radial spacing therebetween for containing a limited quantity of the printing liquid to be carried by the transfer roller to the printing cylinder. A device associated with the encasement feeds a printing liquid supply into the radial spacing for take up by the transfer roller surface.
