摘要： A system and method of communicating efficiently and reliably between a sensor unit and a master unit, especially in a wireless system, is provided. The disclosed techniques require only minimal processing by the sensor unit for communications purposes and as such, the described system and method can be implemented in systems with tight constraints on the sensor unit side in terms of required memory, power consumption, and cost, such as in wearable sensor systems.
摘要翻译： 提供了一种在传感器单元和主单元之间，特别是在无线系统中有效且可靠地通信的系统和方法。 所公开的技术仅需要用于通信目的的传感器单元的最小处理，并且因此，所描述的系统和方法可以在对所需存储器，功耗和成本方面在传感器单元侧具有严格约束的系统中实现，诸如 在可穿戴传感器系统中。

摘要： In an embodiment, a method and system are provided for determining a pedestrian position via dead reckoning on a portable device carried by the pedestrian (or “user”). The device has at least a processor, a 3D accelerometer, and a 3D gyroscope. The 3D accelerometer, and a 3D gyroscope are sampled to calculate device orientation, and then 3D accelerometer samples are gathered during a sensor time frame and an average step frequency is calculated. The user's speed and direction of movement are estimated and a device velocity is calculated relative to a prior device velocity via dead-reckoning. The estimated device velocity is corrected for drift and the pedestrian position is calculated based on the corrected estimated current device velocity.
