Disclosed herein is a golf ball with a cover or mantle, or both, formed from an isophthalic acid polyamide composition and a method of making the same. A local server in communication with this stationary transceiver is configured to respond to a mobile processing-system present within the information portal. The implantable medical device includes battery charging and protection circuitry that controls the charging of the battery so as to assure its reliable and safe operation. The trenches have a minimal effect on the single fundamental mode of the individual shallow etched waveguides because the trenches are located far enough from the ridge waveguides where an evanescent tail of the fundamental mode approaches a minimal power level. The seat drive unit swings the seat member at least along a lateral direction.
