Patent number: 10126102Abstract: An automatic scoring dart target device and a method of using the same are provided. The device includes a dart target, a plurality of image capturing units, a background-shield and a processor. The dart target is made of solid material on which darts are shot. The image capturing units and the dart target are disposed on the same surface. The image capturing units respectively capture a plurality of images at intersecting directions. The background shield is disposed relative to the image capturing units so that the image capturing units can generate the background information. The processor calculates the scores based on the background information and locations of the dart in a selection of two images among the plurality of images individually captured by the corresponding plurality of image capturing units. Thus, the scores of landed darts can be automatically calculated when using the conventional dart target.Type: GrantFiled: January 5, 2017Date of Patent: November 13, 2018Assignee: NVTEK Electronic Co., Ltd.Inventors: Wen-Chih Teng, Chin-Wei Liu

Publication number: 20140021788Abstract: An uninterrupted power supply and detection device wherein a light fixture operates with and is coupled to a driving and linking module and a power supply wire. The driving and linking module connected to the power supply wire can sense a voltage state on the power supply wire. At this time, operation of the light fixture can be controlled by a wired or wireless switch of a control unit. When the voltage state is abnormal, the electricity detecting unit set in the driving and linking module can detect a signal representing abnormal power supply. Thereby, backup power can be supplied for driving emergency illumination of a light emitting element of the light fixture. Accordingly, original operation performed in a general power supply system can be kept and backup power can be supplied to keep illumination of the light fixture when the normal power supply is interrupted.Type: ApplicationFiled: July 23, 2012Publication date: January 23, 2014Inventors: CHING-NAN YANG, Wu-Kun Shih, Wen-Chih Teng
