Patent number: 8438542Abstract: Technologies are described herein for generating a management pack at program build time. Data is received that defines one or more events generated by the application program. Data is also received that defines one or more management classes for the application program. When a request to build the program is received, the data defining the events generated by the program and the data defining the management classes is utilized to generate a management pack for the program in an automated fashion. Once the management pack has been generated, it may be provided to an operations manager application program for use in monitoring the operation of the application program.Type: GrantFiled: December 17, 2007Date of Patent: May 7, 2013Assignee: Microsoft CorporationInventors: Durgesh Nandan, Shuyi Hu, Cheng-Chang Chang

Patent number: 6881020Abstract: A pod transfer system having a retractable mast and a rotatable and vertically movable hoist is disclosed. A first extendable robot is situated under a first overhead transfer (OHT) unit, and a second extendable robot is situated under the second OHT unit. Each extendable robot has a fully retracted position for loading a pod from its respective OHT unit, as well as a fully extended position. The retractable mast is situated between a first conveyer and a second conveyer that are themselves situated between the OHT units. The retractable mast has a default fully extended position and a tool move-in fully retracted position. The hoist is situated on the retractable mast. The hoist is able to load the pod from either robot when the robot is in its fully extended position, and is able to load the pod to one of the conveyors.Type: GrantFiled: April 26, 2002Date of Patent: April 19, 2005Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Cheng-Chang Chang, Chien-Jung Huang

Patent number: 6779760Abstract: A safety system for an overhead transport (OHT) vehicle. In one embodiment, the safety system may include a pair of safety panels provided on opposite sides of the load and unload ports on a tool or stocker. An overhead sensor is provided on the OHT and is operably connected to a light curtain on the tool. In the event that the overhead sensor detects an obstruction in the travel path of the OHT during loading of a pod or cassette into the tool or stocker, the light curtain transmits an emergency stop signal to the tool or stocker controller, which terminates further loading operation of the OHT. In another embodiment, the light curtain assumes the look-down sensing function of the overhead sensor in the event that tool components interfere with the look-down function of the overhead sensor.Type: GrantFiled: December 19, 2002Date of Patent: August 24, 2004Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Cheng-Chang Chang, Li-Ren Lin, Chien-Jung Huang
