摘要： A monitoring device of a main spindle rotation speed in a machine tool displays a variation state of the rotation speed by a rotation speed variation unit using a display unit in the machine tool. The monitoring device includes a variation value setting unit, a drawing unit, a first display unit, and a settable range calculating unit. The settable range calculating unit is configured to calculate a settable range of a variation amplitude and a variation cycle based on a calculation formula. The calculation formula includes the variation cycle, a difference between a first rotation speed and a second rotation speed at mutually different timings among the rotation speeds varied relative to a reference rotation speed, an inertia of a rotating body, a rated output of a motor that drives a main spindle, and a usage proportion to the rated output of the motor.

摘要： Examples of systems and methods for locating movable objects such as carts (e.g., shopping carts) are disclosed. Such systems and methods can use dead reckoning techniques to estimate the current position of the movable object. Various techniques for improving accuracy of position estimates are disclosed, including compensation for various error sources involving the use of magnetometer and accelerometer, and using vibration analysis to derive wheel rotation rates. Also disclosed are various techniques to utilize characteristics of the operating environment in conjunction with or in lieu of dead reckoning techniques, including characteristic of environment such as ground texture, availability of signals from radio frequency (RF) transmitters including precision fix sources. Such systems and methods can be applied in both indoor and outdoor settings and in retail or warehouse settings.

摘要： A method and apparatus for detecting and removing air from a syringe containing a volume of liquid and a volume of gas is described. The method includes moving a piston in the syringe to expel gas through an orifice of the syringe, sensing a movement of the piston in the syringe, and determining when the volume of gas is expelled from the syringe based on a change in the sensed movement. Moving the piston may include applying oscillating force to the piston using an electromagnetic actuator, and displacement and speed of the piston during each oscillation may be sensed. Determining when the volume of gas is expelled may be based on a change in the sensed movement of the piston during one or more oscillations of the piston or based on a comparison to a given reference value.
