Abstract: Position of a transceiver is calibrated using a pair of calibration devices spaced from the transceiver and each other. A calibration wave signal is emitted from one of the calibration devices and detected by the transceiver as well as the other calibration device. The transceiver generates a response wave signal upon receipt of the calibration wave signal which response wave signal is detected by one of the calibration devices. A delay constant for use in distance determination between transceivers is calculated based on the sum of detected transmission and receipt time intervals and the propagation speed of the wave signals.

Abstract: The yarn feeder device (1) of the invention has one or more yarn feeler levers (26), which are movably supported on the housing (2). The yarn feeler lever (26) is movable between an operating position I and a response position II. In the operating I, its crossbar (28) which forms the yarn feeler means is approximately in the same line as yarn guide elements, such as the struts (19, 23) of yarn guide bails (18, 22). Somewhat above its operating position I, the yarn feeler lever (26) meets a stop, past which it is not moved by the yarn (8). To improve the accessibility to the yarn guide elements (19, 23) particularly when yarn is being inserted and threaded in, the stop of the yarn feeler lever (26) is embodied as yielding. The yarn feeler lever (26) can therefore be moved upward manually past the stop on its lower end (28), in order to open up the space enclosed between the yarn guide elements (19, 23).
