Abstract: Provided are tissue webs, and products produced therefrom, that are generally durable, flexible and have improved cross-machine direction (CD) properties, such as CD tensile energy absorption (CD TEA), CD stretch and CD modulus. The inventive tissue products generally comprise multiple tissue plies, such as two or more plies, that have been prepared by through-air drying and more preferably by through-air drying without creping. Moreover, the plies may be produced in a through-air drying process that utilizes a transfer fabric positioned between the forming fabric and the through-air drying fabric where the transfer fabric imparts the nascent web with a high degree of CD strain.

Abstract: System, method, and apparatus for commutating and controlling a multi-phase motor using one output rotor sensor and circuitry that measures time between rotor pole-to-pole transitions is disclosed. The exemplary system, method, and apparatus may utilize the polarity of the single-output rotor sensor and the measured time between the polarity transitions detected by the single-output rotor sensor.

Abstract: A system and method for reducing fan noise by controlling the drive current to the fan motor. In one embodiment the system approximates a linear drive using a number of transistors in parallel and sequentially deploying the transistors. In another embodiment, a scheme is used to activate and deactivate transistors in discrete steps thereby achieving the benefits of the linear controller topology.

Abstract: The invention in the simplest form is a technique to provide for sharing of power and signal pins on a motor controller. The switching simply follows the magnetic switching detected by the Hall sensor as the motor magnet passes and uses a diode or resistor instead of a switch. The power transistors are respectively connected to a voltage regulator through a diode or resistor and there are no switches in the circuit. To avoid simultaneous switching, one embodiment is designed by turning “On” slowly and turn “Off” quickly. Slow “On” is accomplished by using a resistor/capacitor (RC) delay such that the gate drive ramps slowly. Fast “OFF” is obtained by discharging the gate capacitance with an N-CH transistor that bypasses the RC delay.

Abstract: An apparatus for polishing an edge of an automotive glass sheet comprising a retaining device, which is capable of supporting the automotive glass sheet, and a polishing wheel assembly. A motor assembly is coupled to and drives the polishing wheel assembly to polish the edge of the automotive glass sheet to maximize the strength of the glass sheet and improve the aesthetic properties thereof. A pressure system, such as a compliant member, a robotic system, or a floating spindle assembly, is coupled to either the retaining device or the polishing wheel in order to actively maintain a predetermined generally constant contact pressure between the polishing wheel and the edge of the automotive glass sheet to insure proper polishing thereof.
