Abstract: A PIM probe that includes a PIM antenna carried on a wand sized for positioning by hand. The PIM antenna is tuned by loop size to receive PIM corresponding to uplink reception channels of a site antenna generated by downlink broadcast frequencies F1 and F2 of the duplex antenna. The PIM antenna vanes may include conductors printed on a PC boards or wire loops. A PIM probe system includes a signal analyzer that displays a representation of PIM received by the PIM antenna. The PIM probe system further includes an RF filter for passing the PIM frequencies of interest and suppressing the test frequencies transmitted by the site antenna, such as a cellular base station antenna. When the site antenna is broadcasting the test frequencies, the technician places the PIM antenna in various locations to detect the presence of PIM in those locations.

Abstract: Laser drilling devices are disclosed which include a laser beam source and a laser drilling head. The laser drilling head includes a beam manipulator system in which the only dynamically moving optical element is a mirror. The mirror is dynamically and reciprocally translatable along the direction of the incoming laser beam and is also dynamically and reciprocally tiltable about an axis that is perpendicular to the nominal optical axis of the drilling head. The drilling head also includes a spinnable laser beam rotating system, a simplified compensation system, and a focusing system. The compensation system includes as its only laser beam path shifting optical elements one or two wedge plates which, if two, are fixably rotatable relative to one another in planes which are perpendicular to the nominal optical axis of the laser drilling device.

Abstract: A method and apparatus for replacing an individual conduit located within a bank of individual conduits, without rendering inoperable the surrounding adjacent individual conduits of the bank. A conduit expander is pulled through the subject individual conduit to break it and push the pieces out. Knife blades may be used to split the individual conduit. A rearward flared out portion pushes the broken conduit outwardly far enough for a new conduit to be moved therethrough, but not far enough to render inoperable the surrounding adjacent individual conduits of the bank. A replacement conduit is attached to the rear end of the conduit expander and moved into the individual conduit as the conduit expander moves therethrough.
