Abstract: The article of invention is referred herein as a prime polygon reflector. In its various forms it is a device of predetermined geometric shape with aspects and scalable dimensions derived from a prime number and its mathematical square root. Geometric shapes based on the prime polygon have reflective surfaces that cause multiple internal reflections of incident waveform energy. When used in conjunction with absorptive media, coatings, or linings, the waveform energy is forced to pass through absorptive media multiple times, thereby increasing effectiveness of the media, coating, or lining. Prime polygon reflectors as disclosed herein produce waveform reflections that are non-inverted by causing an even number of internal reflections. Applications include but are not limited to acoustic, solar, and radar energy absorption.

Abstract: A method of forming a device having a compliant member includes providing an elastomeric layer in an uncured state. The elastomeric layer is pre-cured to increase its viscosity. Subsequently, a bobbin and housing, each having an end, can be positioned such that their ends extend at least partially into the elastomeric layer. The elastomeric layer is cured to secure it to the bobbin housing. Examples of pre-cure and cure operations include one or more of a thermal cure, evaporative cure and ultraviolet cure, and the application of moisture, microwave energy and chemical additive. Due to the increased viscosity after the pre-cure, the migration of elastomeric material is substantially reduced relative to an uncured elastomeric material. The reduction in elastomeric material migration results in smaller menisci formed along the walls of the housing and bobbin, and reduced thinning of the compliant member formed at their ends.

Abstract: The present subject matter includes a system for communications between a transmitter and a receiver. In various embodiments, the system uses a sleep interval to allow the receiver to go to sleep between wake up times to “sniff” for transmissions from the transmitter. The system adjusts the length of the preamble of the transmitted signal or a repetition of packets to allow the receiver to detect a transmitted signal based on drift in the clocks of the system. In various embodiments, a receive channel is changed if a signal is not received at a prior channel selection. In various embodiments, the transmission is determined by detection of an event. In various embodiments, the event is an ear-to-ear event. In various embodiments, the receiver and transmitter are in opposite hearing aids adapted to be worn by one wearer.
