A Wireless Voice-Link-Module for the Hearing Impaired

简介（由申请人提供）：蓝牙是一种新的短距离无线通信技术，由瑞典爱立信移动通信公司领导的全球公司联盟开发。这项技术的重要优势包括：抵抗其他无线传输的干扰、低成本、低功耗、体积小、编码语言的通用性以及能够形成蓝牙术语中所谓的“皮康网”。piconet是一种扩展使用的无线网络，它允许一个适当装备的单个便携式设备与各种设备（如移动电话和家用电话（无线或硬连线）、计算机、打印机和其他设备）进行接口，只要它们配备了蓝牙收发器，而无需更换硬件。作为蓝牙特别兴趣组（Bluetooth Special Interest Group， SIG）长期目标的一部分，该技术的所有潜在用户都可以获得免费许可，但必须经过设计审查，以确保满足某些功能标准。本应用程序的主要目标是：(1)利用蓝牙技术开发用于听障应用的无线“语音链路模块”（VLM）；(2)证明VLM在不受其他近距离类似系统干扰的宽带教室放大系统中的有效性。这两种系统都将按照营销计划的描述向听力受损社区进行营销。

DESCRIPTION (provided by applicant): Bluetooth is a new short-range wireless communication technology developed by a worldwide consortium of companies led by Ericsson Mobile Communications AB of Sweden. Among the important strengths of this technology are: resistance to interference from other wireless transmissions, low cost, low power consumption, small size, universality of the encoding language and ability to form what are called, in Bluetooth parlance, "piconets". Piconets are are extended use wireless networks that allow a suitably equipped single portable device to interface with a variety of equipments such as cell phones and home phones (wireless or hard-wired), computers, printers and other equipments without change of hardware so long as they are equipped with Bluetooth transceivers. As part of the Bluetooth Special Interest Group (SIG) long term goals, free licences are issued to all would-be users of this technology subject only to design reviews to assure that certain functional criteria are met. The primary goals of this application are: (1) To develop a wireless "Voice Link Module" (VLM) for hearing impaired application using Bluetooth technology; and (2) Demonstrate the effectiveness of the VLM in the context of a wide-band Classroom Amplification System not subject to interference from other similar systems in close proximity. Both of these systems would be marketed to the Hearing Impaired Community as described in the Marketing Plan. During the Phase II portion of this work we will take the developments done during the Phase I work and integrate them into the VLM and the Classroom Amplification System. The Classroom System will be evaluated in a Cambridge, Ma. School as described in the body of this application. We believe that the market potential for these systems are exceptional and will form the basis for using Bluetooth technology in other applications for the Hearing Impaired. Bluetooth Products are being developed for virtually all-wireless applications, but very little effort is being directed towards our market.
