摘要： A fat depth measuring apparatus and method for use in measuring in an animal (10) the depth of a fat layer (14) between hide (12) and muscle (16). An ultrasonic generator (25) generates ultrasonic pulses and an ultrasonic echo detector (25) generates echo signals (26) indicative of ultrasonic pulses received by the detector after reflection from boundaries or discontinuities (13, 15) within the tissues of the animal. Variable gain amplifier (35) amplifies the echo signals (26) and produces detector signals (38). Gain control means (40) varies the gain of the amplifier (35) to increase the probability of having exactly two detector signals (38) identifiable as arising from echoes from a hide/fat boundary (13) and a fat/muscle boundary (15). A fat depth determining means (47) receives the detector signals (38) and if they exceed primary threshold levels (39a, 39b) identifies the two required detector signals (38a, 38b) so as to thereby enable determination of the depth of the fat layer (14). If more than three detector signals have levels exceeding 60 % of the threshold level (39), the depth determination is considered invalid.

摘要： A target (10) for providing coded data readable by an imaging apparatus (30). Location marking means (20) enable location of the target by the imaging apparatus preparatory to an imaging operation, the location marking means having high visibility characteristics e.g. being of retroreflective material (11) to enable identification of the location marking means against a background. Code marking regions (13c-14c) of annular shape include circumferentially disposed code markings (12) containing coded data which are imaged by the imaging apparatus to enable recovery of the coded data from the target. The location marking means (20) is located generally centrally of the code marking regions (13a-14c) so that identification of the location marking means also locates the centre of the code marking regions. The location marking means (20) includes at least one concentric annular region (22) to enable fine location of the centre. The code marking regions (13a-14c) are rotationally dispersed relative to the centre.
