Keeping Up with Wireless Hearing Assistive Technology

A Review of Assistive Listening Device and Digital Wireless Technology for Hearing Instruments

Assistive listening devices (ALDs) refer to various types of amplification equipment designed to improve the communication of individuals with hard of hearing to enhance the accessibility to speech signal when individual hearing instruments are not sufficient. There are many types of ALDs to overcome a triangle of speech to noise ratio (SNR) problems, noise, distance, and reverberation. ALDs va...

Keeping up with calcium

Our understanding of how calcium functions as a second messenger continues to increase at an incredible pace. This symposium covered most, if not all, aspects of the many roles of calcium in the regulation of cellular processes and ranged from calcium imaging through to the structure and function of calcium-binding proteins. Emphasis was placed on elucidating the involvement of these proteins i...

Assistive Technology: Use and Service Delivery

As individuals with long-term disabilities and other older adults face declines in health and function, there is a greater need for assistive technology (AT) or assistive devices and environmental interventions (EI) to help them maintain their independence and community participation. These aids can help older adults and individuals with disabilities function in work, home, recreational, and ot...

Passive wireless tags for tongue controlled assistive technology interfaces.

Tongue control with low profile, passive mouth tags is demonstrated as a human-device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed ...
