  • Publication number: 20180278140
    Abstract: One example includes a switch circuit. The switch circuit includes a transistor configured to activate in response to an activation voltage at an activation terminal of the transistor. The switch circuit also includes a current source coupled to the activation terminal and being configured to generate an activation current. The switch circuit further includes a driver control circuit interconnecting the activation terminal and a voltage rail. The driver control circuit includes digital counter logic configured to cycle through a predetermined number of count values based on an oscillator signal. The driver control circuit is configured to adjust an amplitude of the activation voltage at each of the predetermined number of count values based on the activation current to provide a soft-start activation of the transistor.

  • Patent number: T995001
    Abstract: The pilling propensity of knit fabric from polyester staple fiber can be reduced by scouring the fabric at a temperature in the range of about 160.degree. to 205.degree. F. for from about 15 to 60 minutes in a 0.3 to 1.0% aqueous caustic solution containing about 0.001 to 0.1% of a quaternary ammonium salt of the formula: ##STR1## wherein R is an alkylene radical of 2 to 3 carbon atoms, R' is H or phenyl, R" is a C.sub.12 -C.sub.18 hydrocarbon radical, x is 2 or 3, y is 0 to 3, and Z.sup.- is an anion, preferably the dimethyl sulfate quaternary ammonium salt of bis(hydroxy-tri-1,2-propyleneoxy-2-ethyl)tallowamine. After scouring, the fabric is normally rinsed, neutralized, rinsed again and dried.
