    • The accuracy of a reverse geocode for a GPS fix in a mobile phone navigation device is improved significantly by considering together the user's last known location on an original route, the elapsed time between the last known location on the original route and the latest GPS fix, and the likelihood that the user could have traveled from the last known location on the original route to one of numerous candidate locations (generated from the reverse geocode) in the elapsed time. The navigation server relies only on a GPS fix, timestamps, and a back-end routing database to provide improved or superior accuracy of reverse geocoding a GPS fix (selection of a point on a road) when a relevant user has deviated from the intended route. The reverse geocoding allows for accurate and functional re-routing capabilities.
    • 通过考虑用户在原始路线上的最后一个已知位置,原始路线上的最后一个已知位置与最新的GPS定位之间的经过时间,将移动电话导航设备中的GPS修复的反向地理编码的精度大大提高, 以及在经过的时间内用户可能已经从原始路线上的最后一个已知位置行进到许多候选位置之一(由反向地理编码生成)的可能性。 导航服务器仅依赖于GPS定位点,时间戳和后端路由数据库,以便当相关用户偏离预期路线时,提供GPS定位(GPS选项)对路线进行反向地理编码的改进或更高精度 。 反向地理编码允许准确和功能重新路由功能。

    • A method and system for delivering anti-tachycardia pacing is disclosed. A cardiac rhythm management device, such as an implantable pacemaker having anti-tachycardia pacing capability, delivers anti-tachycardia pacing therapy in accordance with an anti-tachycardia pacing protocol upon detection of a terminable arrhythmia. The anti-tachycardia pacing is delivered as a burst of one or more pacing pulses at a specified coupling interval after a sensed ventricular polarization. By sensing if an evoked potential occurs, the device can determine whether or not the anti-tachycardia pacing burst has captured the ventricle and can adjust the coupling interval and/or other parameters accordingly.
    • 公开了用于递送抗心动过速起搏的方法和系统。 具有抗心动过速起搏能力的心脏节律管理装置,例如具有抗心动过速起搏能力的可植入起搏器,在检测到可终止的心律失常时,根据抗心动过速起搏方案提供抗心动过速起搏治疗。 抗心动过速起搏在感测到的心室极化之后以指定的耦合间隔作为一个或多个起搏脉冲的脉冲串发送。 通过感测是否发生诱发电位,该装置可以确定抗心动过速起搏脉冲是否已经捕获到心室,并且可以相应地调整耦合间隔和/或其他参数。
