摘要： An improved error detection for microprocessor-based transmitters in two-wire process control loops operating in the process control industry. In particular, techniques are shown which are useful in solving malfunctions or failures of microprocessor-based transmitters. When the transmitter is energized, the impedance of the process loop cabling is resolved and stored, displayed or transmitted as desired. The loop impedance is used to calculate potential of a power supply used to power the control loop. This information is used in testing the two-wire loop.

摘要： In this invention, a multivariable transmitter providing an output representative of mass flow has a dual microprocessor structure. The first microprocessor compensates digitized process variables and the second microprocessor computes the mass flow as well as arbitrating communications between the transmitter and a master. In a second embodiment of the present invention, a first microprocessor compensates digitized process variables, a second microprocessor computes an installation specific physical parameter such as mass flow and a third microprocessor arbitrates real-time communications between the transmitter and a master.

摘要： A field mounted transmitter for use in a two-wire process control loop includes a sensor, measurement circuitry and a power supply. The sensor senses a process variable of a process which is transmitted over the control loop by the measurement circuitry. The power supply is powered by a current flowing through the control loop and powers the measurement circuitry. The power supply includes an inductive element coupled to the measurement circuitry and a switch which selectively couples the inductive element to the control loop.

摘要： A cable drive circuit allows a transmitter in a process control system to drive signals across a capacitive length of cable. The cable drive circuit uses a charge pump to store charge, which is then used in conjunction with open drain outputs to transmit logic signals across a cable to a peripheral at the other end of the cable. A microcontroller or other device specifies the number of communication pulses to send across the cable before allowing the charge pump to recharge. By transmitting communication pulses for a small percentage of the time the average current is minimized, making the circuit suitable for operation under the 4-2OmA standard for two-wire devices.

摘要： A driver boost signaling circuit provides a pulse boost to the first cycle of an output pulse wave applied to an associated load. The circuit includes a signal generator circuit generating a signal including a series of pulses, a determining circuit determining a high impedance state of a signal load line and a first one or more cycles of the series of pulses applied to the load line following the high impedance condition, and a receiving circuit receiving a control signal. A logic circuit generates first and second logical signals responsive to the control signal and to the determining circuit determining the first one or more cycles and other cycles of the series of pulses. A switchable impedance circuit coupling the signal generator with the associated load line is responsive to the first logical signal to provide a low impedance level between the signal generator circuit and the associated signal load line, and to the second logical signal to provide a high impedance level between the signal generator circuit and the associated signal load line.

摘要： A method and system for resolving contentions among passive identification tags. A reader may divide a possible range of tag values into a number of smaller ranges. For each smaller range, the reader may then poll the tags to determine which tags have tag values that fall within the smaller range. If more than one tag responds simultaneously, then the reader may further divide the smaller range into even smaller ranges and poll the tags with respect to those even smaller ranges. Once the range partition gets small enough, the reader may then opt to poll the tags for a match of each possible value in the range, rather than partitioning further. This arrangement enables the reader to efficiently identify tags, by quickly eliminating from analysis any range of tag values to which no tags match or only one tag matches.
摘要翻译：一种用于解决被动识别标签之间争用的方法和系统。读取器可以将可能范围的标签值划分成多个较小的范围。对于每个较小的范围，读者可以轮询标签来确定哪些标签具有落在较小范围内的标签值。如果多个标签同时响应，则读取器可以进一步将较小的范围分割成更小的范围，并相对于更小的范围轮询标签。一旦范围分区变得足够小，读者可以选择轮询标签以获得该范围内每个可能值的匹配，而不是进一步划分。这种安排使得读者能够通过快速地从分析中消除任何标签值与任何标签匹配或仅一个标签匹配的任何范围。
