摘要:
Systems and methods for monitoring a paging signal from a mobile switch to a cellular transmitter for occurrences of congestion. The system includes a switch; a cell site in communication with the switch, for broadcasting a page received from the switch to a cellular device configured to receive the page; and a monitoring module in communication with the switch for monitoring occurrences of paging congestion between the switch and the cell site.
摘要:
A shield apparatus for use with a powered vegetation trimmer of the type including a trimmer head assembly having an output shaft and a cutting mechanism rotatable with the output shaft. The shield apparatus is mounted coaxially about the output shaft between the cutting mechanism and a head portion of the head assembly. The shield includes first and second outer walls coaxially disposed about the axis of rotation of the output shaft. The first outer wall circumscribes at least a portion of the cutting element to define a distal annular gap. The second outer wall circumscribes at least a portion of the head portion of the head assembly to define a proximal annular gap. The shield isolates the output shaft from the area surrounding the cutting mechanism so as to prevent vegetative matter from contacting the output shaft, or at least minimize such contact.
