摘要： A hand-held antenna system allows medical personnel to ascertain the presence or absence of objects (e.g., medical supplies) tagged with transponders in an environment in which medical procedures are performed. In use, the hand-held antenna system may be positioned proximate a patient at a time after a medical procedure, such as after child birth, so the system can scan the patient's body to determine the presence of objects tagged with transponders. The antenna system includes three antenna elements arranged mutually orthogonal to each other to transmit and receive signals in three coordinate directions. A controller is coupled to the antenna elements to transmit signals to the transponders and to receive response signals. The antenna system may operate in a static scan mode wherein the antenna system is held in a fixed position by a user and a dynamic scan mode wherein the antenna system is moved by a user.

摘要： The presence or absence of objects is determined by interrogating or exciting transponders coupled to the objects using pulsed wide band frequency signals. Interrogation is broken down into a number of subsample scan cycles each having interrogation cycles a start time forward in time by a fraction of a period of an expected transponder response signal. Ambient or background noise is evaluated and a threshold adjusted based on the level of noise. Adjustment may be based on multiple noise measurements or samples. Noise detection may be limited, with emphasis placed on interrogation to increase the signal to noise ratio. Matched filtering may be employed. Presence/absence determination may take into account frequency and/or Q value to limit false detections. Appropriate acts may be taken if detected noise is out of defined limits of operation, for example shutting down interrogation and/or providing an appropriate indication.
摘要翻译：物体的存在或不存在通过使用脉冲宽带频率信号询问或激发与物体耦合的转发器来确定。询问被分解成多个子采样扫描周期，每个子采样扫描周期都具有询问周期，时间上的开始时间是期望的应答器响应信号的一段时间的一段时间。评估环境噪声或背景噪声，并根据噪声水平调整阈值。调整可以基于多个噪声测量或样本。噪声检测可能受到限制，重点放在询问上以增加信噪比。可以采用匹配滤波。存在/不存在确定可以考虑频率和/或Q值以限制错误检测。如果检测到的噪声超出了限定的操作范围，例如关闭询问和/或提供适当的指示，则可以采取适当的行为。
