Patent number: 10915718Abstract: A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.Type: GrantFiled: December 21, 2018Date of Patent: February 9, 2021Assignee: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Nai-Chun An, Yuan-Chih Lin, Hsiu-An Tsai, Shuo-Ching Chen, Chih-Lung Lin

Patent number: 9841298Abstract: A measurement device for a linear stage includes a two-dimensional grating and a measurement unit respectively disposed on first and second moving stages of the linear stage. The measurement unit includes a light source, a two-dimensional sensor and a processor. The light source emits incident light to the two-dimensional grating so that the incident light is reflected thereby to result in reflection light. The two-dimensional sensor receives the reflection light and converts the same to a reflection signal. The processor receives the reflection signal and determines accordingly a first rotational angle, and first and second displacement components of a displacement of the first moving stage.Type: GrantFiled: December 30, 2016Date of Patent: December 12, 2017Assignee: Metal Industries Research And Development CentreInventors: Hsiu-An Tsai, Shuo-Ching Chen, Kuo-Yu Chien
