Disclosed are a method, a device, a system, and/or manufacture of electronic book enhancement. In one embodiment, a device includes a housing, a book coupler to secure a book to the housing, a page detection sensor generating a page signal usable to determine an open page of the book, a computer processor, a computer readable memory, and an audio output device. The computer readable memory stores an audio dataset including one or more page UIDs, one or more associated audio files, and an audio routine that includes computer readable instructions that when executed receive the page signal from the page detection sensor, determine a page UID for the open page, query the audio dataset for the audio file associated with the page UID, and generate an audio signal of the audio file on the audio output device to enhance a reading experience of the book based on the open page.

Device, system, and method for electronic book enhancement

A specialized variable speed drive of the present invention is capable of controlling a motor and increasing the efficiency of both an ACIM or DCBL motor by biasing operation in favor of a class AB mode. The variable speed drive may be configured with two gate drivers where one gate driver is a class D gate driver and the second gate driver is either a class AB gate driver or a class C gate driver. The system also operates to reduce electro-magnetic interference in the operation of motors while increasing the reliability of the overall VSD system.
