    摘要: A bag filler consisting of a single tubular member has a peripheral portion removed from one end thereof to form a hand grip while an opposing peripheral portion at the same end then forms a scoop, has its other end inserted into the open end of a bag to be filled, and the bag at both its ends is then turned about and within the associated ends of the tubular member so that an operator may with one hand hold both the open end of the bag and the hand grip of the tubular member for guiding the bag and bag filler into engagement with material from which the bag is to be filled, while the operator's other hand holds the bag and other end of the tubular member to propel the bag and bag filler.

    摘要: A mesh network is initiated by using multiple frequency bands for establishing communication between mesh nodes. In one aspect, a higher or lower frequency communication link may be established depending on the range between two mesh nodes. As the mesh network increases and decreases in density, and range and communication aspects change, a communication link may be change between the higher and lower frequency bands as necessary.
