    摘要: A voltage protection circuit for controlling an input data signal on a signal-carrying line to a binary data-storage device having an input line for receiving the input data signal comprises two transistors in series having current-control electrodes coupled to an input control terminal and a third transistor having its current-control electrode coupled to the input line with one current-conducting electrode coupled to a voltage source and another current-conducting electrode coupled to current-conducting electrodes of the first two transistors.

    摘要: A method of freemium based marketing includes providing a utility consumer with an offer for a freemium requiring the consumer to respond to the offer. When the consumer responds to the offer, consumer data is collected and a bundle of additional consumer products are selected based on the consumer data. The bundle of additional products may include home service products. The method then offers the consumer an opportunity to purchase products from the selected bundle. The method then provides the user with the freemium.
