    • Passive tags use two antennas with only limited mutual coupling one of which receives a power/clock field and the other of which receives a data signal. An area-reading antenna, or two or more antennas, are deployed to generate the power/clock field, from a base station. The base station, or active tags, or both, generate the data signals from time to time. This topology together with the use of low frequencies permits area reads, and permits small and economical passive tags, and further permits localization of a particular passive tag as being nearby to a particular active tag.

    • A system uses a large loop antenna, connected with a transceiver operating below 1 MHz. The loop antenna is deployed from a spool to surround a crime scene, and may carry indicia communicating that it is a crime scene boundary. The system interrogates devices, including evidence bags and badged personnel, as they enter and leave the scene. The system can optionally log the time of salient events. A second loop antenna can log evidence bags as they enter a vehicle. The devices can be silenced by the transceiver and thus collisions can be reduced and avoided among responses from devices. The system performs “area reads” that would not be possible if higher RF frequencies were employed.
    • 系统使用大型环形天线,与低于1 MHz的收发器相连。 环形天线从卷轴部署到围绕犯罪现场,并且可以携带指示它是犯罪现场边界的标记。 系统在进入和离开现场时,对装置进行询问,包括证件袋和标识人员。 系统可以选择记录突出事件的时间。 第二个环形天线可以在进入车辆时记录证据袋。 这些设备可以被收发器静音,从而可以减少和避免设备响应之间的冲突。 如果采用较高的射频频率,系统将执行“区域读取”。

    • The invention disclosed provides a method, system, and associated tag for detection and tracking of inanimate and animate objects. The novel method broadly comprises the steps of: a) attaching a low radio frequency detection tag to each of the objects, each tag comprising a tag antenna operable at a low radio frequency not exceeding 1 megahertz (preferably not exceeding 300 kilohertz), a transceiver operatively connected to the tag's antenna, the transceiver being operable to transmit and receive data signals at the low radio frequency, a data storage device operable to store data comprising identification data for identifying said detection tag, a programmed data processor operable to process data received from the transceiver and the data storage device and to send data to cause the transceiver to emit an identification signal based upon the identification data stored in said data storage device, and an energy source for activating the tag's transceiver and data processor; b) storing, in the data storage device of each tag, shipping data selected from object description data, address-of-origin data, destination address data, object vulnerability data, and object status data; c) commingling the objects in a repository selected from a warehouse and a truck, the repository being provided with at least one large loop field antenna operable at said low radio frequency; the field antenna being disposed at a distance from each object that permits effective communication therewith at the low radio frequency, d) reading the identification data and shipping data from the transceiver of each tag by interrogating all tags commingled in said repository with data signals, such as specific IP addresses or other identification codes, via said field antenna; and e) transmitting the identification data and shipping data from each tag to a central data processor to provide a tally of the objects in said repository.

    • A package storage and delivery system includes electronically controlled lockers disposed at or near customer locations. Each locker is unlocked by a courier, preferably by means of a short-range transceiver or transmitter carried on the courier's person. The customer can unlock the locker and receive the delivered package. Cryptographically signed communications are employed along with nonvolatile usage logs to minimize the risk of loss of a package or fraud by courier or customer. The lockers may be stackable, permitting a delivery courier to add lockers in the event a customer receives too many deliveries to fit into a single locker. Each box has, of course, a physical location, and has associated with it an address code indicative of the physical location, for example by means of a human-readable or compressed representation of the precise latitude and longitude. A package delivered to such a box preferably bears the address code. A merchant can greatly reduce the risk of credit card fraud by requiring the use of such codes for the simple reason that a fraudulent transaction may be traced to a specific physical location.
    • 包裹储存和运送系统包括设在客户位置或附近的电子控制柜。 每个储物柜由快递公司解锁,最好是通过快递员身上的短距离收发器或发送器。 客户可以解锁储物柜并接收交付的包裹。 密码签名的通信与非易失性使用日志一起使用,以尽量减少快递或客户丢包或欺诈的风险。 储物柜可以是可堆叠的,允许送货快递员在客户收到太多交货以适应单个储物柜的情况下添加储物柜。 当然,每个盒子都有一个物理位置,并且与它相关联一个表示物理位置的地址代码,例如通过精确纬度和经度的人类可读或压缩表示。 交付给这样的盒子的包装件优选地承载地址码。 商人可以通过要求使用这样的代码来大大降低信用卡欺诈的风险,原因很简单,就是将欺诈性交易追溯到特定的物理位置。
