    摘要: A tracking device can use a permanent encryption key pair to encrypt a temporary private key that corresponds to a set of diversified temporary public keys. When a community mobile device subsequently detects the tracking device, the central tracking system provides a diversified temporary public key to the community mobile device. The community mobile device uses the diversified temporary public key to encrypt location data representative of a location of the community mobile device, and provides the encrypted location data to the central tracking system. When a user subsequently requests a location of the tracking device from the central tracking system, the central tracking system provides the encrypted temporary private key and the encrypted location data to a device of the user, and the device can decrypt the encrypted temporary private key using the permanent encryption key pair, and decrypt the encrypted location data using the decrypted temporary private key.

    摘要: A stage device includes a stage having a copper main body and an electrostatic chuck, a cooling unit disposed below the stage, and a power supply mechanism for supplying power to an attraction electrode of the electrostatic chuck from a DC power supply disposed below the stage. The power supply mechanism includes a pair of terminals disposed at an outer peripheral portion of the stage while being spaced apart from each other, a first power supply line having a pair of metal rods spaced apart from each other while extending toward the stage and being connected to the DC power supply, a second power supply line having a pair of metal rods spaced apart from each other and connected to the terminals, and a connecting unit where the metal rods of the first power supply line and the metal rods of the second power supply line are connected.

    摘要: A computer-implemented method, gaming device and computer-readable medium for video game. The method includes maintaining a virtual space for a gaming environment. The method also includes repeatedly activating an event zone in the virtual space, wherein for one or more game objects having a position in the virtual space that is within the event zone when the event zone is activated, a state of the one or more game objects in the virtual space is changed. The method further includes displaying on a display device a visual representation of the event zone and a visual representation of a marker, the marker having a position in the virtual space. The method yet further includes changing the position of the marker such that a distance involving the marker and at least part of the event zone is related to a time remaining before the next repeated activation of the event zone.

    摘要: Digital data corresponding to a trace by a device is received. The digital data includes location data and time data obtained over a period of time and representing movement of the device. A set of derived values for the plurality of metrics is calculated from the sets of values corresponding to the metrics, and the set of derived values is input to a machine-learned classification model to determine whether the received digital data represents movement of a first type. In response to determining that the digital data represents movement of the first type, the received digital data corresponding to the trace is labelled with the first type of movement.

    摘要: A computer-implemented method, non-transitory computer-readable medium and apparatus for dynamic management of formations in a video game. The method includes maintaining a virtual three-dimensional environment and causing a plurality of video game characters to travel along a path in the virtual three-dimensional environment in a formation. The formation has a formation type and the formation type is a first formation type. The method also includes moving the formation along the path. The method also includes, responsive to determining a change in characteristics of the path at a point in the virtual three-dimensional environment that is ahead of the formation, changing the formation type to a second formation type in advance of the change in characteristics of the path.

    摘要: A system securely provisions a resource for access by computing systems of an untrusted network. The provisioning is performed securely such that at no stage during the process the computing systems of the untrusted network have direct access to the computing systems of the trusted network. The system creates a temporary network connected to the trusted network and provisions the requested resource in the temporary network. The system connects the temporary network to the trusted network for provisioning of the resource. The system disconnects the trusted network from the temporary network before connecting the untrusted network to the temporary network for providing access to the resource.

    摘要: Systems and methods are disclosed herein for performing a time-triggered distribution of messages from a region of networked machines to multiple destinations. In an embodiment, the system runs a software-based synchronization process to synchronize each of a plurality of gateways with a reference clock, wherein each gateway is a machine on a perimeter of the region of networked machines and is connected to transmit messages to multiple destinations. The gateways receive messages from within the region of networked machines for distribution to multiple destinations outside the region of networked machines according to a distribution schedule based on absolute time relative to the reference clock. The gateways perform the distribution of received messages, wherein each gateway determines absolute time based on that gateway's synchronization with the reference clock.
