Abstract: An analog-to-digital converter for converting an analog input signal to a digital output signal is described. The ADC includes a comparator circuit having first to nth stages of comparators responsive to the analog input signal. Each comparator includes a plurality of magnetoelectronic devices for performing comparison function. Each magnetoelectronic device has one or more ferromagnetic elements capable of being switched into a first or second magnetization states. The amplitude of analog input signal upon exceeding a predetermined threshold level (IS or VS) of a respective magnetoelectronic device sets a magnetization state of the respective magnetoelectronic device to the first state and the resulting output of the respective magnetoelectronic device to a HIGH state, and vice-versa. In one embodiment, the magnetoelectronic device is a Hybrid Hall Effect device. In another embodiment, the magnetoelectronic device is an isolator.

Abstract: In accordance with this invention a wood working machine is provided which facilitates the sequential working of opposite sides of a wooden work piece to form a flange for a cable reel. The work piece is grippingly held against a work piece support while the support moves downwardly to permit working on one side of the work piece with a first set of working elements and then moves upwardly to permit working on the other side of the work piece by a second set of wood working elements after which the support returns to its initial position and the work piece is released for removal from the apparatus.
