A signal digitizing system and method based on analog-to-time optical mapping, optically maps amplitude information of an analog signal of interest first into wavelength information using an amplitude tunable filter to impress spectral changes induced by the amplitude of the analog signal onto a carrier signal, i. The labelform combination document is constructed of two separate materials joined together at a coplanar joint. and hence the speed at which a content-buffer on the MHD is replenished changes. A signal processing unit determines a distance between the third sensor and the adjacent object in accordance with a signal strength calibration as a function of the third sensor signal. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic polymers. After the target value is changed so that the intake valve openscloses in accordance with a specific value of the valve characteristic, the operating position of the mechanism is learned as a reference position for the control of the valve characteristic.
