Patent number: 8120504Abstract: A circuit for indicating operating status of a plurality of hardware devices of a computer includes a detecting module, a decoding module, and an indicating module. The indicating module includes a dual color indicator and two electronic switches connected to a first input and a second input of the dual color indicator respectively. The detecting module detects an operating status of the plurality of hardware devices, and outputs state signals of each hardware device during power on self test of the computer. The decoding module decodes the state signals, and outputs level control signals to turn on or off the two electronic switches. The dual color indicator indicates operating status of the plurality of hardware devices by shifted to be at different indicating states by the two electronic switches correspondingly.Type: GrantFiled: December 22, 2008Date of Patent: February 21, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventors: Xun-Chun Qiu, Guang-Dong Yuan, Chung-Chi Huang, Rong Hu

Patent number: RE45681Abstract: A tool changer comprising a master module and a tool module includes a rapid-connect communication bus between the master and tool modules. A unique tool identification number, along with other tool-related information, may be transmitted from the tool module to the master module within about 250 msec of the master and tool modules coupling together. The master module includes a robotic system communications network node connected to the rapid-connect communication bus, and operative to transmit data between the tool and the network via the communication bus. The need for a separate network node in the tool module is obviated, reducing cost and reducing the start-up time required to initialize such a network node upon connecting to a new tool. The rapid-connect communication bus may be a serial bus.Type: GrantFiled: September 13, 2013Date of Patent: September 29, 2015Assignee: ATI Industrial Automation, Inc.Inventors: Dwayne Perry, Richard I.
