    摘要: A method and apparatus is provided that provides a reliable diskless network-bootable computers using a local non-volatile memory (NVM) cache. The NVM cache is used by the computer when the network is temporarily unavailable or slow. The cache is later synchronized with a remote boot server having remote storage volumes when network conditions improve. It is determined if data is to be stored in the NVM cache or the remote storage volume. Data sent to the remote storage volume is transactionally written and the data is cached in the NVM cache if a network outage is occurring or a transaction complete message has not been received. The data stored in the NVM cache allows the user to continue operating during network outages and the computer can be cold-booted using the data in the NVM cache if the network is unavailable.

    摘要: A computer is adapted for use in different operating modes by configuring an output controller, such as a graphics processing unit, to screen output signals prior to presenting them to the output device. A secure environment in the output controller verifies a digital signature or a hash of the output signal to determine whether the output signal is compatible with the current mode of operation. Thus only authorized output signals are presented when the computer is operating in a limited function mode, such as when metered usage time is expired. The apparatus and method also disclose similar output signal screening for determining whether the computer should be returned from a standby, or no-metering, mode to an active, or metered mode.

    摘要: An active matrix for a capacitive multiple touch sensing device is disclosed. One embodiment comprises one or more active matrix capacitive touch sensing pixels that each include a capacitor and a thin film transistor, wherein a voltage can be applied to the thin film transistor to address the capacitor. In this way, the thin film transistor can operate as a switch to apply an alternating current to the capacitor, and the capacitor's capacitance can be measured in relation to the alternating current and an externally applied electric field.

    摘要: A system for binding a subscription-based computer to an internet service provider (ISP) may include a binding module and a security module residing on the computer. The binding module may identify and authenticate configuration data from peripheral devices that attempt to connect to the computer, encrypt any requests for data from the computer to the ISP, and decrypt responses from the ISP. If the binding module is able to authenticate the configuration data and the response to the request for data from the ISP, then the security module may allow the communication between the computer and the ISP. However, if either the configuration cycle or the response cannot be properly verified, then the security module may degrade operation of the computer.

    摘要: Active vibration techniques are described. In implementations, a selection of a type of writing surface or a type of writing implement is received, the selection made through interaction with a user interface. The selected type of writing surface or type of writing implement is simulated using vibrations of a stylus or surface of a computing device that is configured to receive one or more inputs from the stylus.
