Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A device dynamically collects runtime data while the device is continuously executing an application to identify the cause of a performance bottleneck. The device hardware first collects data of high-level performance events that indicate alternative causes for the performance bottleneck. Based on real-time analysis of the data, a first performance event is identified among the high-level performance events for causing the performance bottleneck. The device hardware is then re-configured to collect additional data of lower-level performance events that are under the first performance event and indicate additional alternative causes more specific than the alternative causes. The collecting, identifying, and re-configuring are performed while the device is continuously executing the application.

Abstract: A method provides device selective suspension feature when the operating system does not allow certain device drivers to perform device selective suspension. Two driver stacks are provided in the kernel space for the device. The first driver stack includes a virtual bus, a PDO (physical device object) created by the virtual bus, and a driver for the device (e.g. NDIS driver); the second stack includes a device driver stack (e.g. USB generic driver) and a function driver that performs device selective suspension by sending power IRPs to the device driver stack. By using a virtual bus and PDOs created by the virtual bus in the first driver stack, the driver above the PDO can be any one of many types of drivers (NDIS driver being one example). The virtual bus forwards IRPs from the first driver stack to the second driver stack.

Abstract: A low power switching mode driving and sensing method for capacitive multi-touch systems is used in a capacitive multi-touch system with a capacitive touch panel. When the capacitive touch system operates in an idle mode, the method uses a self-capacitance driving and sensing technology to detect touch points. When the touch points are detected on the capacitive touch panel, the capacitive touch system is switched to an active mode and uses a mutual-capacitance driving and sensing technology to detect touch points for accurately acquiring the positions related to the touch points detected. During a predetermined time interval in which there is no touch point detected, the method automatically performs a calibration to update a mutual-capacitance base image raw data and a self-capacitance base image raw data, so as to overcome the drifting of sensors of the capacitive touch system.

Abstract: A USB device enumeration process implemented in a USB device is described. The USB device first detects a type of the operating system (OS) of the USB host connected to the device, and performs device enumeration using a process selected from multiple stored processes based on the detected host OS type. To detect the host OS type, the USB device first presents itself to the host as a USB MSD or HID, performs device enumeration to collect OS behavior factors from the host, and determines the OS type from the OS behavior factors. Thereafter, the USB device performs actual device enumeration by presenting itself as the USB device it actually is, using an enumeration process specific to the detected host OS type. The multiple stored enumeration processes are customer configurable. Further, a method is provided to stop an enumeration process when the host is in a BIOS stage.
