Publication number: 20230113086Abstract: An adjustable sander having a body and a flexible base. The flexible base includes a first end and a second end spaced apart from one another. The first end and second end are each pivotally attached to the body. The flexible base is configured to move between a concave configuration, a neutral configuration, and a convex configuration relative to the body. The adjustable sander further includes a removable sanding surface affixed to a surface of the flexible base that is distal from the body. The adjustable sander also includes a locking mechanism configured to selectively hold the flexible base in a desired concave, neutral or convex configuration. The locking mechanism is characterized in that it includes an axial having a head and a shaft having a series of shaft notches.Type: ApplicationFiled: October 6, 2022Publication date: April 13, 2023Inventors: ChihChiang LEE, Wan-Chiang WANG, Hui-Mei CHANG, Yen-ting WU, Yi Tung CHAN, Tsung-Chih TSAI, Yu-Wei TSAI

Patent number: 10610448Abstract: A spa apparatus may comprise a cart, a magnifying lamp, a phototherapy mask, a bed, and a bathtub. A computer, a storage battery, and a communicator are electrically connected and installed inside the cart, and the cart is electrically connected to a power outlet and a display, which enables the cart to be moved and used not limited by the location of power supply. Moreover, the cart has a drawer and a spacing for the storage of beauty products and tools, and through sequentially connecting to a front arm, a rear arm, and a base, the phototherapy mask is configured to be used in different angles and to be held above or in front of a user's in a preferable height.Type: GrantFiled: May 29, 2018Date of Patent: April 7, 2020Assignees: Yi Jin Shiuan Beauty Co. Ltd., Dept. of Electrical Engineering, National Changhua University of EducationInventors: Hui-Mei Chang, Tsair-Rong Chen

Patent number: 10524590Abstract: A wrench support rack including a base, and at least one clamp assembly attached to the base and comprising a vertical stop spaced apart from a push member. The space in between the vertical stop and the push member forms a groove configured to receive a stem of a wrench. The vertical stop includes an upper ridge portion configured to engage a stem of a wrench and limit vertical movement of a wrench disposed in the groove. The push member includes an inward protrusion configured to press a stem of a wrench in to the vertical stop and limit horizontal movement of a wrench disposed in the groove.Type: GrantFiled: August 30, 2017Date of Patent: January 7, 2020Assignee: Stanley Chiro International Ltd.Inventors: Yen-ting Wu, Chihchiang Lee, Wan-chiang Wang, Yi Tung Chan, Ching-Yi Tu, Hui-Mei Chang

Patent number: 8922225Abstract: A sensing pad includes a first sensing layer, a second sensing layer and a spacer layer. The second sensing layer has at least one second sparse sensing zone and at least one second dense sensing zone. The spacer layer is disposed between the first sensing layer and second sensing layer, and includes at least one high pressure spacer zone and at least one low pressure spacer zone. The second sensing layer is pressed downwards upon receiving a load to compress the spacer layer and contact the first sensing layer to generate electric connection, thereby detecting the pressed location. Through the dense sensing zone and sparse sensing zone distributed on the second sensing layer whether a person is lay on a bed can be judged to reduce faulty judgments, and the posture of the person can be detected to better understand conditions of the person lay on the bed.Type: GrantFiled: June 7, 2012Date of Patent: December 30, 2014Assignee: China Medical UniversityInventors: Jin-Chern Chiou, Shih-Che Lo, Hsin-Hsueh Tsai, Jia-Hung Yan, Fong Yuan Chang, Hui-Mei Chang
