    • Methods of post-slaughter handling a carcase are presented in a first example a carcase is hung from its symphysis pubis and cut by; (1) removing the knuckle, fillet end and chump from the rest of the carcase; and, (2) separating the knuckle from the fillet end and chump by cutting at an angle of less than 45.degree. to the back line of the carcase. In a second example the carcase is hung from its symphysis pubis and cut by; (1) removing the leg and chump from the rest of the carcase; (2) removing at least the pelvic bones; (3) straightening the leg. In a further example, the method comprises (1) hanging the carcase from its symphysis pubis; and (2) applying high voltage stimulation to the carcase.

    • An optical device for reading one- and two-dimensional symbologies at variable depths of field, the device including a light source for projecting an emitted light towards the two-dimensional image and an optical assembly, or zoom lens, with dual field of view capability for focusing light reflected from the framed symbology onto a CCD detector for detecting the focussed light and generating a signal therefrom. The dual field of view capability enables scanning of both wide and narrow fields of view. An apodizing filter is provided within the optical assembly to increase depth of field. Aiming of the sensor to read the symbology is facilitated by a frame locator including a laser diode which emits a beam that is modified by optics, including diffractive optics, to divide the beam into beamlets having a spacing therebetween that expands to match the dimensions of the field of view of the sensor, forming points of light at the target to define the edges of the field of view. One or two sets of diffractive optics may be provided, with one set corresponding to each position, for each of the dual field of view positions of the zoom lens.

    • A technique for acquiring and tracking terminals in a free-space laser communication system involves exchanging beacon laser beams between the terminals to acquire and then track the terminals such that data laser beams exchanged by the terminals for communication are steered based on feedback from detection of the beacon laser beams. The beacon laser beams used for acquisition have a greater beam divergence than those used for tracking. Gimbals provide coarse steering of the data laser beams, and steering mirrors provide fine steering. GPS position data exchanged via an RF link can be used for initial pointing of the beacon laser beams for acquisition. The beacon laser beams can be chopped such that all terminals can use the same beacon wavelength and are distinguished by using different chopping frequencies. By detecting a chopped signal, the position sensor detector can be AC coupled to reduce sensitivity to solar radiation and glint.
    • 用于在自由空间激光通信系统中获取和跟踪终端的技术包括在终端之间交换信标激光束以获取并跟踪终端,使得由终端用于通信的交换的数据激光束被基于来自检测的反馈 信标激光束。 用于采集的信标激光束具有比用于跟踪的光束发散更大的光束发散度。 万向表提供数据激光束的粗略转向,而转向镜提供精确的转向。 通过RF链路交换的GPS位置数据可以用于用于采集的信标激光束的初始指向。 信标激光束可以被切碎,使得所有终端可以使用相同的信标波长,并且通过使用不同的斩波频率来区分。 通过检测斩波信号,位置传感器检测器可以被AC耦合以降低对太阳辐射和闪烁的敏感度。
