Abstract: A golf mat that has a natural feel and mitigates injury during mat striking includes: a base, the base including a main structure with an upper surface and an open topped cavity in the upper surface; and an insert sized to be accommodated in the cavity, the insert including a layer of solid polymeric material selected to have shock absorption properties greater than the main structure; and artificial turf installed on the base and overlying at least a portion of the main structure and the insert.

Abstract: An annular seal for a conduit pig includes an annular diaphragm and a separate lead support structure. The annular diaphragm is devoid of internal supports and therefore quite flexible. However, the lead support structure supports the annular diaphragm such that a piston effect can be generated through the annular seal. A brush portion for a conduit pig may include forwardly raked bristles.

Abstract: A golf practise mat including a stance section and a ball strike section. The stance section is segmented into a plurality of planar components so that the golf may can be disassembled for shipping and storage. A kit is disclosed including the components and instructions for assembly. A golf practise mat may also have one or more swing training devices for installation of golf training rods.

Abstract: A golf practice mat assembly and a method for constructing a golf practice range is provided. The golf practice mat assembly comprising; a stance section with a first end, a second end, positioned opposite the first end, a front lengthwise side extending between the first end and the second end and a second lengthwise side extending between the first end and the second end; a strike section including a first side and an opposite side; a connection between the stance section and the strike section, the connection configured to securely and detachably connect the strike section to the stance section and the connection further configured to be angularly selectable and to connect the strike section at one of a plurality of possible angular orientations relative to the stance section.

Abstract: A brush useful in pipeline pigs, for example, in magnetic flux leakage tools or cleaning tools, a method of making the brush and pipeline pig comprising the brush. The brush has a metal bristle holder and a plurality of bristles, the ends of which are held in the bristle holder by glue, swaging or a combination of glue and swaging. The glue may be an anaerobic glue. The brush and method of making avoid the use of heat to secure the bristles to the bristle holder, avoid the use of solder or weld metal, and are less labor intensive than soldering or welding.

Abstract: A handheld communication device having an RF front end module has a switchable balun comprising a primary winding having a first two port winding and a second two port winding where a low noise amplifier is operatively coupled to the first and second two port windings and a power amplifier is operatively coupled to the first and second two port windings. A secondary winding is operatively coupled to an antenna, and a transceiver is operatively coupled to the low noise amplifier and the power amplifier. When the switchable balun is in a receive state, the antenna is operatively coupled to the transceiver through the low noise amplifier, and when the switchable balun is in a transmit state, the antenna is operatively coupled to the transceiver through the power amplifier. The ratio of the primary winding to the secondary winding is greater than a one-to-one ratio.

Abstract: A pipeline pig brush and method of assembly of the pipeline pig brush is provided. The pipeline pig brush has a body with a plurality of recesses provided in an outer surface. A number of brushes, each brush having a ferrule and a tuft of bristles, can be mounted to the body, wherein the ferrule of each brush is inserted into the recess and a removable fastener is installed to engage the body and overlap the ferrule such that the ferrule cannot be removed from the recess without removing the fastener.

Abstract: A golf practice mat including a surface pattern formed by thermally deforming and allowing setting of the deformed mat surface.
