HSK taper comparing and measuring instrument

Abstract: The utility model relates to an HSK taper comparing and measuring instrument. A traditional taper comparing and measuring instrument has many disadvantages. An HSK, which is a handle used for high-grade machine tools of a high cutting speed, is rapidly popularized due to excellent performance in the aspects including rigidity, radial jump precision, repeated installation precision and cutter service life. The HSK taper comparing and measuring instrument comprises a large-diameter annular gauge (1), a low-diameter annular gauge (2), a standard plug gauge (3), inductive sensors (4) and an electrical box (7), wherein the standard plug gauge is connected with both the large-diameter annular gauge and the low-diameter annular gauge, one inductive sensor is connected with both the large-diameter annular gauge and the low-diameter annular gauge, the lower end of each inductive sensor is fastened via fastening screws, fixing pivots are fastened via the fastening screws, and cable joints of the inductive sensors are connected with the electrical box. The HSK taper comparing and measuring instrument can be applied to measurement in which the HSK taper needs to be compared.

Inductive proximity sensor and method for detecting proximity

Abstract: The sensor has a magnetic device for generating a magnetic field with magnetic flux density (Bf) for a measurement period, where the device is modulatable. A magnetic sensor is provided as a hall element with two pairs of electrical connections at opposing sides. One of the pairs of electrical connections is connected with a power source, and the other pair of electrical connections taps hall voltage (Uh) as a sensor parameter, where the hall voltage is generated transverse to a direction of current (Ih). A microcontroller stores and multiplies the sensor parameter. An independent claim is also included for a method for detecting proximity using an inductive proximity sensor.

Wearable Posture Monitoring Sensor

Abstract: The ability to perform rehabilitation at home has many advantages, both in terms of greater efficiency in the health service and comfort for the patient. The monitoring of human physiological parameters at home has to be non-invasive for the patient. This paper describes a wearable system for monitoring physiological posture during rehabilitation exercises for the spine. The system is able to measure the posture of the subject through a T-shirt instrumented using an inductive sensor. This paper reports the conceptual framework and a description of the first tested device. The preliminary experimental results are reported and compared with results obtained through an optical system that measures the position of markers placed on the back of the patient. In this work, the system is manufactured and tested with a commercial impedance analyzer.
