摘要： A transponder communicates information on a physical condition to a remote location, without the need for a local power supply or any wire or optical communications with the remote location, by detecting the physical condition and encoding information on the condition into a reprogrammable portion of the transponder memory for transmission in response to an interrogation signal. The encoder is preferably formed from an oscillator that provides an output signal whose frequency is a function of the information provided by the detector, and a counter that accumulates a count which is a function of the oscillator frequency, with the counter programming the memory in accordance with its accumulated count. A variable capacitor, resistor or inductor is preferably used to detect the physical condition and vary the oscillator's output frequency. A bubble wrap-type variable capacitor is particularly useful for monitoring the quantity of air within a tire.

摘要： A wireless modem employs a radio frequency (RF) transponder system components to remotely access the memory of an electrical or electro-mechanical device by providing an exciter/reader/writer (ERW) circuit free of electrical contact with the electrical or electro-mechanical device and a transponder including a transmit/receive antenna, a reading circuit, a programming circuit, and a transponder memory. The transponder memory is directly connected to the device memory. The ERW circuit initially generates an RF excitation signal powering the transponder. In response to the RF excitation signal, the transponder generates a RF response signal using the reading circuit that is transmitted back to the EWR circuit. The RF response signal includes data from the device memory. The RF response signal is received by the ERW circuit, which in turn generates an RF write signal that is transmitted to the transponder. The RF write signal powers the transponder and programs the device memory using the programming circuit of the transponder.

摘要： An electronic anti-shoplifting system monitors articles of merchandise in a sales outlet to deter shoplifting. The system is provided with transponder tags connected to the articles of merchandise. A tag exciter is positioned at an exit leading from the sales outlet and generates an RF surveillance excitation signal. If a customer carries an article through the exit without removal authorization due to failure to pay for the article, the transponder tag is activated, being powered by the RF surveillance excitation signal as the customer passes the tag exciter. The activated transponder tag generates an RF surveillance response signal that triggers an alarm. If the customer has removal authorization as the result of paying for the article, the transponder tag is reprogrammed to modify the operational data stored therein. The operational data typically includes data to alter the frequency of an RF response signal generated by the transponder tag, the frequency of an RF excitation signal to which the transponder tag responds, and/or the type of modulation used by the transponder tag to generate an RF response signal. Sales data, such as the purchase price and date of purchase, is also stored in the transponder tag. When the customer exits the sales outlet after the transponder tag is reprogrammed, the transponder tag does not generate the RF surveillance response signal that triggers the alarm. However, the sales data stored in the transponder tag can be accessed by the clerk of the sales outlet at a later date.
摘要翻译：电子防盗系统监控销售商店的商品，以防止商店盗窃。该系统具有连接到商品的转发器标签。标签激励器位于从销售口导出的出口处，并产生RF监视激励信号。如果客户由于无法支付商品而通过出口携带文章而没有取消授权，则当客户通过标签激励器时，应答器标签被激活，由RF监控激励信号驱动。激活的应答器标签产生触发警报的RF监视响应信号。如果客户因为物品付款而取消了授权，则转发器标签被重新编程以修改存储在其中的操作数据。操作数据通常包括用于改变由应答器标签产生的RF响应信号的频率的数据，应答器标签所响应的RF激励信号的频率和/或由应答器标签用于产生转发器标签的调制类型 RF响应信号。销售数据（如购买价格和购买日期）也存储在转发器标签中。当应答器标签被重新编程后，当客户退出销售点时，应答器标签不产生触发报警的RF监视响应信号。然而，存储在应答器标签中的销售数据可以由销售商的职员在以后访问。

摘要： An RF transponder system is provided that is capable of detecting and correcting data transmission errors. The RF transponder system includes an exciter that generates an RF excitation signal and a transponder that receives the RF excitation signal and is powered thereby. The transponder generates and transmits a RF response signal including a plurality of data sets each containing a common message. At least one of the data sets is encoded in a manner different from the remaining data sets. The RF response signal is received by a reader that decodes the encoded data sets. Corresponding bits of each of the data sets are compared for purposes of error detection. If a majority of corresponding bits from each of the data sets match, a valid bit is defined thereby. Bits that are not in the majority are discarded. An invalid bit is defined where less than a majority of corresponding bits match a selected bit of a selected data set.
