**Introduction**Mobilus Labs (formerly named Noto Technologies LTD) is a company dedicated to developing a new generation of hands-free voice communications systems that exploit the principle of bi-directional bone conduction. This technology enables users, wearing personal protective equipment (ear defenders, safety helmets, respirators), to hold normal conversations with people and devices. Mobilus' lead product is a modular clip-on communication module that retrofits to the rear of a standard safety helmet and enables the user to access voice based systems (communication, voice control) regardless of their surroundings. The aspirational concept is a product that enhances the safety and productivity of people working in the construction/industrial sector.**Innovation**This concept is intrinsically novel, while parties have integrated bone conduction into consumer products Mobilus is unique in developing an industrially focused device for the PPE sector with two-way voice comms. Furthermore, the business has developed extensive IP and knowhow in the technologies required to ensure the appropriate quality and differentiation of wanted and unwanted acoustic signals in the presence of extreme noise.**Project motivation**Mobilus has developed an advanced prototype of the Mobilus solution using investor and Innovate UK funds (project \#9045, project-end: November 2019), this hardware unit is now the focus of commercial exploitation outside the remit of this application. However, the performance of the commercially available transducer components being used is currently limiting the true potential of the larger solution. The business needs to research, design, and develop their own bi-directional bone conduction transducer in order expand commercial growth and meet user expectations which include:* Hands free full-duplex voice communication (versus Push-to-Talk interfaces)* Ear-free compatibility with industry standard PPE* Resilience to environmental noise above 100dB* Resilience to high levels of Electromagnetic interference* Acoustic power efficiency to enable a device to last for a full 14 hour shift on a single charge.The motivation for this project is to enable the company to conduct a programme of technical research and development to develop this novel bi-directional bone conduction transducer that fully exploits the benefit of the Mobilus ear and hands free industrial communication platform. This R&D will enable the business to conduct crucial applied research and testing, supported by leading industrial actors and a set of expert subcontractors with vital access to expertise and facilities needed to develop and validate the Mobilus system.

**简介**Mobilus Labs（前身为Noto Technologies LTD）是一家致力于开发利用双向骨传导原理的新一代免提语音通信系统的公司。该技术使用户能够在佩戴个人防护设备（耳罩、安全帽、呼吸器）的情况下，与人和设备进行正常对话。Mobilus的主要产品是一种模块化的夹式通信模块，可以安装在标准安全帽的后部，使用户能够在任何环境下访问基于语音的系统（通信、语音控制）。理想的概念是一种产品，可以提高在建筑/工业部门工作的人的安全和生产力。**创新**这一概念本质上是新颖的，而各方已将骨传导集成到消费产品中，Mobilus在为PPE部门开发具有双向语音通信的工业重点设备方面是独一无二的。此外，该公司还开发了广泛的知识产权和技术诀窍，以确保在极端噪声存在的情况下，适当的质量和区分所需和不需要的声学信号。**项目动机**Mobilus使用投资者和Innovate UK资金开发了Mobilus解决方案的先进原型（项目\#9045，项目结束：2019年11月），该硬件单元现在是该应用程序范围之外商业开发的重点。然而，目前使用的商用传感器组件的性能限制了更大解决方案的真正潜力。企业需要研究、设计、并开发自己的双向骨传导传感器，以扩大商业增长并满足用户期望，其中包括：*免提全双工语音通信（相对于一键通接口）*与行业标准PPE的无耳兼容性*对100dB以上环境噪声的弹性*对高水平电磁干扰的弹性*声功率效率，使设备能够在一次充电中持续工作14小时。该项目的动机是使公司能够开展技术研究和开发计划，以开发这种新型双向骨传导换能器，充分利用Mobilus耳朵和免手工业通信平台的优势。这项研发将使企业能够进行关键的应用研究和测试，由领先的工业参与者和一组专家分包商提供支持，这些分包商可以获得开发和验证Mobilus系统所需的专业知识和设施。
