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: A permanent magnet alternator (PMA) includes a rotatable shaft, windings, a shunt regulator circuit, and a speed detection circuit. The rotatable shaft is connected electromagnetically to the windings. The shunt regulator circuit is electrically connected to the windings. A current sense transformer with a primary coil is electrically connected to the shunt regulator circuit. A secondary coil is electrically connected to a comparator circuit with reference voltage and generates voltage pulse indicating PMA speed. The voltage pulses form an output corresponding to and indicative of rotation speed of the shaft suitable for processing by a processor to present a PMA speed indication for use in the overall system architecture as a measurement parameter.

Abstract: A direct current-to-direct current (DC-DC) power supply includes a voltage converter module that converts an input voltage having a first voltage level into an output voltage having a second voltage level that is less than the first voltage level. An over-voltage detection module receives the second voltage and generates an over-voltage signal indicating an over-voltage condition of the DC-DC power supply. A shutdown module receives the over-voltage signal and generates a shutdown signal in response to the over-voltage condition. An over-voltage protection module interposed between the shutdown module and the input of the voltage converter module. The over-voltage protection module is configured to selectively inhibit delivery of the input voltage to the voltage converter module in response to the shutdown signal.
