Abstract: Embodiments include an antenna assembly for a wireless microphone, comprising a helical antenna including a feed point and at least one contact pin coupling the feed point to the wireless microphone. The helical antenna is configured for operation in first and second frequency bands. Embodiments also include a wireless microphone comprising a main body having top and bottom ends and an antenna assembly coupled to the bottom end. The antenna assembly comprises a helical antenna configured to transmit and receive wireless signals, an inner core configured to support the helical antenna on an outer surface of the inner core, and an outer shell formed over the inner core and the helical antenna. Embodiments further include a method of manufacturing an antenna assembly for a wireless microphone using a first manufacturing process to form a core unit of the antenna assembly and a second manufacturing process to form an overmold.

Abstract: This invention relates to ion exchange resins that have a reduced amount of physically adsorbed organic compounds, as well as methods of producing and using such resins. In particular, the amount of extractable total organic carbon on the resins may be less than about 200 parts per trillion by wet weight, as measured using gas chromatography/mass spectrometry. This invention also relates to methods of treating water that use such resins.
