Abstract: A system capable of low power personnel detection is based on a focused linear array of passive infrared detectors sampled and processed over time. For example, an exemplary system can have a sensor that captures infrared line images for personnel detection by scanning through a sensing plane of a linear array's field of view. In such a system, a processor controls the array sensor and stores the resulting images. Velocity characteristics of moving objects are incorporated into the images over time resulting in horizontal velocity profile images. Long wave infrared (LWIR) radiation can be sensed, which works in day and night conditions without illumination. LWIR sensors, such as microbolometers, as well as pyroelectrics, can be used.

Abstract: A bucket of a type designed to attach to the stick of an excavator, using pre-existing pins. The bucket is powered by a hydraulic cylinder, the lines of which attach to excavator controls. Striker forks are mounted onto the stick of the excavator at a predetermined position. The clean-out system is a wiper plate incorporated into the bucket as the “roof”, which is designed to follow the inner contour of the sides of the bucket. As the bucket is filled, the wiper plate moves to the top of the bucket; when the bucket is emptied, the wiper plate contacts the striker forks, which force the material out of the bucket, preventing build-up of material on the inside of the bucket.

Abstract: A fish scaling tool with a scaling portion and a shank for removable insertion into the chuck of rotary drive device. The cylindrical scaling portion has pointed ridges which spiral (with a slight pitch) around the longitudinal axis of the shank. Equally-spaced longitudinal grooves in the scaling portion provide device for removing scales. Secondary cutting surfaces are provided by equally-spaced longitudinal notches in the scaling portion. A cup-shaped splash guard for deflecting detached scales and water can be attached to the shank of the tool.

Abstract: A clam bucket of a type designed to attach by way of a pin (20) through vertical lugs (92) to the stick of an excavator making the attachment process fairly simple. These vertical lugs (92) are part of the rotational housing (32) assembly which, in conjunction with a rotational mounting plate (22) at the top of a square tubing extension (48) enable the bucket (70) to make a full 360° turn. The bucket (70) halves are each powered by a hydraulic cylinder (56), the lines of which attach to excavator controls. The clean-out system is a pair of wiper plates (86) incorporated into the bucket (70) halves. These wiper plates (86) sweep the bucket (70) halves each time the bucket opens and closes preventing buildup of material. This self-cleaning hydraulic clam bucket can be manufactured in size to suit the consumer.
