Abstract: An information handling system includes a battery and a charger. The battery provides a battery voltage to a main power rail of the information handling system and is couplable to the main power rail through a switch. The charger has an output coupled to the main power rail and an input coupled to an external power adapter. The power adapter provides a selectable voltage level to the input. The information handling system selects a particular voltage level that is lower than the battery voltage and directs the switch to decouple the battery from the main power rail when the information handling system is in a soft power-off state.

Abstract: Multiple models for various stages of a non-linear process control are developed by clustering perturbation data obtained from the nonlinear process so as to permit multiple local data regions to be identified as a function of substantial similarity between the data, wherein the data of first data set represent the non-linear process. A discrete model corresponding to each of the local data regions is generated. The number of the discrete models may be reduced as a function of prediction error between actual outputs of the process and predicted outputs of the models and as a function of a gap metric based on closed loop similarity and frequency response similarity between the models.

Abstract: One embodiment of the application provides a system for visualizing trend data of an industrial performance (e.g., utility consumption) of a power plant. The system includes a macro trend view generator, navigator, a pointer position calculator, and a micro trend view controller. The macro trend view generator is configured to generate a macro trend view of a sensed parameter in a display. The navigator is configured to navigate a pointer for locating an area in the macro trend view. The pointer position calculator is configured to calculate a position of the pointer in the macro trend view. The micro trend view controller is configured to generate a micro trend view associated with the located area in the display, as a function of the calculated position of the pointer in the macro trend view.

Abstract: A stack of pre-formed bags, each bag of the stack comprising: a body portion formed by front and rear walls having closed sides, a closed bottom and an open mouth; spaced apart handles extending from the body portion; and front and rear tabs extending from the front and rear walls respectively, the tabs being located between the handles, wherein the front and rear tabs are separably attached to the handles at attachment points spaced from the mouth of the bag the arrangement being such that a bag can be removed from the stack without leaving any waste material behind.

Abstract: A chemical solution coating apparatus, having a carrier board and a plurality of spray apparatuses. The carrier board is to carry the wafer to be coated, and the spray apparatuses are located at a periphery of the carrier board to evenly spray chemical solution on the wafer. Since the chemical solution is coated on the wafer in a spray manner, so that the unnecessary lapse and process cost are avoided. The number and spraying angle spray apparatuses can be adjusted to reach an optimum status.

Abstract: A dispensing system used in a spin coater is provided to transport a solvent to a wafer. The dispensing, system includes a switch valve, a sucking-back valve, a solenoid valve, a speed control unit of the sucking-back valve, and a speed control unit of the switch valve. The switch valve controls a solvent dispensing status. The sucking-back valve receives the solvent from the switch valve and exports the solvent to a wafer. The solenoid valve controls the switch valve and the sucking-back valve. The speed control unit of the switch valve is coupled between the switch valve and the solenoid valve and is used for a control of action speed on the switch valve. The speed control unit of the sucking-back valve is coupled between the switch valve and the sucking-back valve, and is used for a control of action speed of the sucking-back valve by a sufficient delay time of action.

Abstract: A photoresist dispensing system used in a photoresist coating machine includes a pump, a sucking-back valve, a solenoid valve, a first pump speed controller, a second pump speed controller and a sucking-back speed controller. The pump is used to transport photoresist and spray a substrate. The sucking-back valve is used to suck back liquid photoresist from a transporting duct end. The solenoid is used to activate or inactivate the pump and the sucking-back valve. The first and the second pump speed controllers are separately coupled between the pump and the solenoid valve, and the sucking-back speed controller is coupled between the sucking-back valve and the sucking-back speed controller is coupled between the sucking-back valve and the route, where is between the pump and the second pump speed controller. Hence, the sucking-back valve produces a sucking force after the pump is inactivated and releases a sucking force after pump is activated.

Abstract: A SOG coater nozzle pot includes a pot for containing fluid and letting the fluid in the pot flow out, a funneled nozzle including a wider opening for receiving fluid from the pot and a narrower opening on a protuberance inserted into a duct, and a mounting device for mounting the funneled nozzle on the SOG coater. The nozzle pot according to the invention makes the mounting/dismounting operations of the pot more convenient and less time-consuming. The stability of the SOG coater is maintained as well.

Abstract: The present invention discloses a stepper vacuum chuck wiper for cleaning a stepper vacuum chuck, which includes a rod frame, a bearing device, a flare type soft shield, a wiping stick and an illuminating device. The rod frame has a through hole at one end and the bearing device is sleeved inside of the through hole. The flare type soft shield with a flare opening on its lower end is sleeved inside the bearing device, and the diameter of the flare opening is larger than the outside diameter of the bearing device. The wiping stick is sleeved inside the flare type soft shield. The illuminating device for illuminating the stepper vacuum chuck includes a light source, a battery set and a switch. The battery set is coupled to the other end of the rod frame to provide electricity to the light source, and the switch is coupled between the battery set and the light source to control the illumination of the light source, wherein the light source and the switch are disposed on the rod frame.
