摘要： The present invention relates to locating a person who is operating a wireless communications device in an indoor environment. In particular, it relates to processing various combinations of RSSI, direction of arrival and flight time characteristics of a signal, as received at two or more and preferably three or more access points. In one embodiment, the access points implement a wireless LAN (WLAN) and the communications device is a telephone operating over the WLAN. In another embodiment, the localization of a wireless device allows a system to reject users who are outside a predefined physical area.

摘要： A variable gain analog amplifier is described that uses pulse-density modulation in the form of a sigma-delta modulator (SDM) to produce a gain by modulating the selection of a switch that selects the amount of resistance in a negative feedback loop of the amplifier. The output of the SDM is dithered to increase the gain resolution of the analog amplifier, wherein the increased resolution produces a quiet, inaudible transition between changes in gain setting at an output of the variable gain amplifier and in addition produces a quiet, inaudible mixing and merging of audio signals.

摘要： Communication processing paths include distortions, such as DC offset in the baseband analog path which needs to be accounted for. The use of a digital-to-analog converter (DAC) to inject a DC offset cancellation signal can bring about noise/area/power advantages. The DAC is driven by a mixed signal low pass filter loop. However, the DAC could also be driven in an open loop system, or a combination of open and closed loop. A low noise sign and magnitude DAC with low area and power requirements is implemented using selectively connected programmable current sources to virtual earth input terminals on a transimpedance amplifier (TIA) op-amp circuit. The constant virtual earth voltage eliminates linearity problems that would otherwise exist due to the finite current source output impedance. Current sources are only switched in when required so unneeded sources are out of circuit and do not contribute noise or use any power.

摘要翻译： 通信处理路径包括失真，例如需要考虑的基带模拟路径中的DC偏移。 使用数模转换器（DAC）注入直流偏移消除信号可以带来噪声/面积/功率优势。 DAC由混合信号低通滤波器环路驱动。 然而，DAC也可以在开环系统中驱动，也可以是开环和闭环的组合。 具有低面积和功率要求的低噪声符号和幅度DAC通过使用选择性连接的可编程电流源到跨阻抗放大器（TIA）运算放大器电路上的虚拟接地输入端子来实现。 恒定的虚拟接地电压消除了由于有限的电流源输出阻抗而将存在的线性问题。 电流源仅在需要时才开关，因此不需要的电源不会出现电路，不会产生噪音或使用任何电源。

摘要： The invention provides a system for evaluating a patient featuring: 1) an ECG-measuring system connected to the patient and configured to sense ECG information from the patient; 2) a data-acquisition system interfaced to a vital sign-monitoring system configured to sense vital sign information from the patient during an electro-physiology (EP) procedure; and 3) an external software system interfaced to both systems. The external software system includes a first software interface that receives ECG information measured from the patient by the ECG-measuring system, and a second software interface that receives vital sign and EP-related information from the data-acquisition system measured from the patient during an EP procedure. A database stores physiological and EP-related information measured from the patient before, during, and after the EP procedure. And an algorithm interfaced with the database determines an efficacy of the EP procedure by collectively analyzing information measured during each of these phases.
