    • SAW devices such as interdigital transducers (IDTs) have been widely used in RADAR applications and as filters. An IDT produces a SAW when excited by a single electrical pulse and can be fabricated to embody a code, which code provides for a passive autocorrelation of a SAW input to the IDT and thereby lends itself to further application as a signal generator in a communication device. However, internal dimensions of IDTs are inversely proportional to operating frequency, such that high frequency IDTs present significant manufacturing difficulties. Fabrication of IDTs for high frequency applications is simplified by exploiting a harmonic frequency SAW generated by IDTs. An IDT may therefore be designed according to fundamental frequency internal dimension criteria but can operate at a multiple of the fundamental frequency, thereby providing much higher frequency operation than conventional SAW systems. A communication system based on SAW harmonic techniques would be low-cost, low-power, small and simple alternative to known short range communications schemes, including for example the Bluetooth™ solution. Operation of a second harmonic SAW system at 2.4 GHz based on a fundamental frequency of 1.2 GHz is contemplated.
    • 诸如叉指式换能器(IDT)之类的SAW器件已被广泛应用于雷达应用和滤波器。 IDT在由单个电脉冲激励时产生SAW,并且可以被制造为体现代码,该代码提供SAW输入到IDT的无源自相关,从而使其进一步用作通信设备中的信号发生器 。 然而,IDT的内部尺寸与操作频率成反比,使得高频IDT存在显着的制造困难。 通过开发由IDT产生的谐波频率SAW,可以简化高频应用的IDT的制作。 因此,IDT可以根据基本频率内部尺寸标准设计,但是可以以基频的倍数工作,从而提供比常规SAW系统高得多的频率操作。 基于SAW谐波技术的通信系统将是低成本,低功率,小而简单的替代已知的短距离通信方案,包括例如Bluetooth TM解决方案。 考虑到基于1.2GHz的基频的2.4GHz的二次谐波SAW系统的操作。

    • A method of sensing the concentration level of at least one particular electrolyte in the sweat fluid of a subject, includes providing a sweat sensor system having sweat fluid absorbing material, measuring apparatus for sensing the electrical conductivity of sweat fluid absorbed by the absorbing material and producing ionic concentration data for said at least one particular electrolyte, and a user interface connected to the measurement apparatus for interpreting the data to a user. The absorbing material is applied to the skin of the subject to cause sweat fluid thereon to be absorbed by the absorbing material whereby the measurement apparatus produces ionic concentration data for the sweat fluid absorbed and the user interface interprets the data for a user.
