Abstract: An integrated circuit is described. This integrated circuit may include: a receive circuit, coupled to a segment of a LIN bus, that receives bits; a measurement circuit, coupled to the receive circuit, that measures: a rising-edge time and a falling-edge time in the bits, or a bit time and a second bit time in the bits; control logic, coupled to the measurement circuit, that compares the rising-edge time and the falling-edge time, or the bit time and the second bit time; a transmit circuit, coupled to the receive circuit, that transmits the bits on a second segment of the LIN bus; and a delay circuit, coupled to the control logic, that applies, based at least in part on the comparison, a delay to: one or more rising edges or falling edges in the bits; or one or more bit times or second bit times in the bits.

Abstract: A communication device is provided which transmits and responds to differential currents. Thereby allowing communication between devices that may be floating with respect to each other.

Abstract: A method and apparatus for correlating requirements of educators, guiding documents, and educational resource providers is described. The apparatus includes a central correlator accessed by each of the external entities using keys established according to a uniform protocol. The correlator includes a central database including a range of elements describing in varying levels of detail a field of study. Each of the external users correlates a set of components, such as the components of a teaching plan, to the elements in the central database. The apparatus correlates the several sets of components to the external user's set of components and provides the various correlations through a variety of outputs.
