摘要： A disclosed device and method are useful for monitoring a tube bending process. An example sensor detects a force associated with moving a mandrel in tubing during at least a portion of a tube bending process. The detected force is used to determine a quality of the tube bending process. For example, a detected pulling force provides an indication of whether a bent portion of a tube is within an acceptable range of a desired configuration. The detected pulling force is also useful to provide an indication of whether a condition of a mandrel or a machine used during the process is as expected.

摘要： A device for determining the quality of a part includes a sensor for detecting a strain on a selected portion of a part forming machine. A controller utilizes the detected amount of strain to make a determination regarding the quality of a corresponding part. In one example, the sensor detects a compressive or tensile strain on a machine frame when the sensor is aligned to detect a strain parallel to a direction of a force applied during the part formation process. The controller uses one or more characteristics of the sensor output and determines whether the detected amount of strain is within an acceptable range. In one example, monitoring the strain during the formation of a plurality of acceptable parts provides information for determining the acceptable range. The disclosed arrangements allow for making part quality determinations without requiring a sensor to be “in line” with the load.

摘要： A sensor device includes at least one piezoelectric polymer film supported on a plate that is positioned relative to a machine such that a force used during a manufacturing process involving the machine is incident on the plate. The piezoelectric polymer film provides an electrical output indicative of the incident force. In a disclosed example, a single piezoelectric polymer film extends across a substantial portion of a surface area of the plate. In another disclosed example, a plurality of piezoelectric polymer film sensor elements area are arranged symmetrically about a location where the incident force is expected to be most prominent.

摘要： A descending bid auction system includes preregistered bids from remote locations. Preregistered bids submitted before an auction cycle begins are awarded a sale when the pricing device declines to a price that matches that of the preregistered bid. In keeping with traditional Dutch auction style, in one example, local bidders who submit a bid are given priority because of the first-submitted tradition. Similarly, when more than one remotely submitted preregistered bid is for the same price, the first such bid submitted is given priority. An alternative way of using a remote bidding terminal designed according to this invention is to competitively bid while an auction cycle is in process. Bids submitted while the auction cycle is in process preferably are submitted when a remote clock, which operates in advance compared to the auction site clock, reaches a desired price. the remote bid preferably is received at the auction site before the auction site clock reaches the intended price.
