The first switch has first and second terminals for respectively receiving the mirrored cell and reference currents. The second and third switches have first terminals respectively coupled to the first and second terminals of the first switch, and control terminals respectively coupled to the second and first terminals of the first switch. The fourth switch is connected to second terminals of the second and third switches.

Abstract:
A method for auto updating application program suitable for a global position system (GPS) navigator is provided. The method comprises the following steps. First, a map-update short message is sent to the GPS navigator at a client terminal from a wireless station. Then, a map-downloading program inside the GPS navigator is woken up when the GPS navigator receives the map-update short message. Then, connecting to a map server through the map-update short message when a user decides to update the map. Accordingly, a newest electronic map can be downloaded from the wireless station.
Abstract:
A multiple system image options selective booting method and interface is proposed, which is designed for use in conjunction with a computer platform for the user to select a desired system image from multiple available options contained in a system image source (such as a CD-ROM module) for booting up the computer platform with the user-selected system image. This feature allows the user to more conveniently select a desired system image from a collection of system image options for booting up a computer platform.
Abstract:
A system and method which is capable of compensating for unintended elevations in process temperatures induced in a substrate during a semiconductor fabrication process in order to reduce or eliminate disparities in critical dimensions of device features. The system may be a plasma etching system comprising a process chamber containing an electrostatic chuck (ESC) for supporting a wafer substrate. A chiller outside the process chamber includes a main coolant chamber, which contains a main coolant fluid, as well as an compensation coolant chamber, which contains an compensation coolant fluid. A main circulation loop normally circulates the main coolant fluid from the main coolant chamber through the electrostatic chuck to maintain the chuck at a desired set point temperature.
