Abstract: A computer includes a processor, a PCIe-compatible interface bus that includes a root that is connected to the processor, and a routing complex that is connected to the root and is controlled by the processor. The computer also includes a first interface slot that is connectable to the root by the switches, a second interface slot that is connectable to the root by the switches, and an extended interface slot that is connectable to the root by the switches. The switches are configured based on properties of a first peripheral device to define a first switching configuration when the first peripheral device is connected only to the first interface slot and to define a second switching configuration when the first peripheral device is connected to both of the first interface slot and the extended interface slot.

Abstract: Circuits, methods, and apparatus that may determine one or more characteristics relating to a mains power supply received by a computer system, and may then determine a maximum amount of power that may be drawn by the computer system given the determined characteristics. An example may provide a computer system having a power supply circuit that may include a detection circuit to receive a mains power supply and to detect a characteristic of the mains power supply. In response to the detected characteristic, the detection circuit may provide an output to a circuit in the computer system that sets a limit on a current that may be drawn by the circuit. In this example, the characteristic may be an RMS value of the mains power supply waveform, a location of where the mains power supply is being received, a quality of the mains power supply, or other characteristic.

Abstract: Ground detection of a touch sensitive device is disclosed. The device can detect its grounded state so that poor grounding can be selectively compensated for in touch signals outputted by the device. The device can include one or more components to monitor certain conditions of the device. The device can analyze the monitored conditions to determine the grounding condition of the device. The device can apply a function to compensate its touch signal outputs if the device determines that it is poorly grounded. Conversely, the device can omit the function if the device determines that it is well grounded.
