    摘要： Systems, devices, and methods for automatic data collection. An automatic data collection system includes an image capture subsystem and a processor subsystem. The automatic data collection system is operable to decode machine-readable symbols in a machine-readable symbol reading mode, and to automatically switch from a machine-readable symbol reading mode to an optical character recognition mode in response to information encoded in a machine-readable symbol. In some embodiments, the automatic data collection system is further operable to perform optical character recognition on human-readable symbols in a human-readable symbol reading mode.

    摘要： A system and method of scanning machine-readable symbols with a signal source modulated by a local oscillator to create by heterodyne mixing upconverted signals at the sum and difference frequencies of the local oscillator frequency and the frequency of the time-varying reflectance off the scanned symbols is disclosed. The reflected heterodyned signal is detected by a receiver. Ambient noise is filtered out from the reflected signal, and the received signal at the sum and difference frequencies is processed.

    摘要： At least one identification (ID) number is used to effectuate communication between a radio frequency (RF) number and a radio frequency identification (RFID) base station. In accordance with a first embodiment of the present invention, at least a first ID number and a second ID number are stored on an RF transponder. Upon receipt of a write request, the RF transponder compares an ID number portion of the write request with the second ID number stored on the RF transponder. If the numbers matched, then a data portion of the write request is stored on the RF transponder. If the ID numbers do not match, then the write request is ignored. In accordance with a second embodiment of the present invention, the RF transponder is adapted to determine the second ID number using at least a portion of the first ID number. For example, the second ID number could be a subset of the first ID number, determined using an algorithm that is based (at least in part) on a portion of the first ID number, etc. In accordance with a third embodiment of the present invention, the second ID number is independent of the first ID number. For example, the second ID number could be a constant that is unrelated to the first ID number. In accordance with a fourth embodiment of the present invention, the data portion of the write request is stored on the RF transponder before the ID number portion of the write request is compared to the ID number stored on the RF transponder. If the ID number portion of the write request matches the ID number stored on the RF transponder, then the stored data is left undisturbed. If, however, the ID numbers do not match, then the stored data is erased (e.g., replaced with a null set, the original data, etc.).

    摘要翻译： 使用至少一个标识（ID）号来实现射频（RF）号码和射频识别（RFID）基站之间的通信。 根据本发明的第一实施例，至少第一ID号和第二ID号被存储在RF转发器上。 在接收到写请求时，RF转发器将写请求的ID号部分与存储在RF转发器上的第二ID号进行比较。 如果数字匹配，则写入请求的数据部分被存储在RF转发器上。 如果ID号不匹配，则写请求将被忽略。 根据本发明的第二实施例，RF应答器适于使用第一ID号码的至少一部分来确定第二ID号码。 例如，第二ID号可以是使用基于（至少部分地）第一ID号码的一部分上的算法等确定的第一ID号码的子集。根据本发明的第三实施例 发明，第二ID号与第一ID号无关。 例如，第二ID号可以是与第一ID号无关的常数。 根据本发明的第四实施例，在将写入请求的ID号部分与存储在RF转发器中的ID号进行比较之前，将写请求的数据部分存储在RF转发器上。 如果写入请求的ID号部分与存储在RF发送应答器上的ID号码相匹配，则保存的数据不受干扰。 然而，如果ID号不匹配，则存储的数据被擦除（例如，被替换为空集合，原始数据等）。

    摘要： An optical assembly includes a first tubular member having a pitched bearing surface proximate one end; a second tubular member having a pitched bearing surface proximate one end; a coupling tubular member fixedly coupled to the second tubular member and rotatably and slideably coupled to the first tubular member; and an optical element received in at least one of the first, the second or the coupling tubular members. At least a portion of the pitched bearing surface of the first tubular member is in engaging contact with at least a portion of the pitched bearing surface of the second tubular member. Rotating the first tubular member with respect to the second tubular member smoothly varies a distance between the first and second tubular members and allows a large, smooth adjustment with little effort. Rotation in a single direction returns the distances to an initial starting point.

    摘要： A proxy RFID read/write unit is used in conjunction with a non-RFID enabled network printer to add a capability to a local area network (LAN) to encode RFID transponders that are either embedded in print media or separate from the print media. The proxy RFID read/write unit is adapted perform the following functions: (a) detecting a message packet directed to the network printer containing a command to print a bar code label; (b) recovering information from at least one data field of the message packet; and (c) writing the information to an RFID transponder. If the network printer is adapted to print onto label media containing embedded RFID transponders, and the RFID interrogator is oriented with respect to the network printer so that a mouth of the printer is disposed within the interrogating range, the information can be written to an RFID transponder embedded in a corresponding print label of the label media.
