An electret microphone assembly in which an insulating support disposed between the apertured front and back walls of a conductive housing has an enclosed portion contained in the housing and an exposed portion extending out of the housing through an opening formed in the side wall thereof. The support carries the back electrode of an electret microphone on the front of the enclosed portion and an FET amplifier circuit on the back of the same portion. Respective electrical contacts formed on the back of the exposed portion of the support extend inwardly through the side opening in the housing to provide external connections to the source and drain of the FET and to the amplifier common line.

Abstract:
A method of making a variable capacitor microphone in which the fixed capacitor element is formed by first coating the metallized surface of a relatively rigid insulating substrate with a polarizable dielectric material and then placing the substrate on one of a pair of spaced electrodes positioned in an ionizable gas and subjecting the gas to the action of alpha rays to produce ions in the space between the electrodes while applying a potential across the electrodes to cause ions to migrate toward the dielectric material to polarize the same to form an electret. After the fixed capacitor element has thus been formed, it is mounted in spaced relationship to a flexible diaphragm to form a microphone.
A hand-held microphone assembly for use with two-way communications equipment in which an electret-capacitor microphone is mounted in the upper surface of the barrel portion of a pistol-shaped casing. A push-to-talk trigger disposed at the end of the barrel actuates a double-pole, double-throw slide switch to couple the output of a local preamplifier in the casing to an audio output line leading from the casing and to make suitable couplings between three changeover lines. A resilient conductive strip disposed within the casing at the inner end of the slider element is actuated in response to the operation of the double-pole switch to couple the preamplifier to a normally disconnected amplifier power supply in the casing.
CEO Paul Cote told 25 Investigates the agency is operating at half capacity due to a staffing shortage. In an email he writes: Day Programs today are operating at approximately 40 to 50% of their pre-COVID in-person capacities. Up until September 2021 it was COVID Safety protocols that limited the
