Abstract: Configuration management of devices from multiple vendors using a hardware abstraction capability is provided. Abstraction between a high-level representation and vendor specific terminology may assist in translating configuration commands and operational status indicators to a single consistent presentation interface. Information may be obtained from computer devices to represent operational metrics of a corporate network infrastructure. Collected metrics may be translated for consistency across vendors. Similarly, configuration commands may initially be provided without regard to vendor specific syntax. Utilizing the high-level abstracted representation, a user interface representation of operational status (without regard to vendor terminology) may be provided for a heterogenous rack of associated components from at least two different vendors. Collected data may be analyzed to provide predicted failure of components.

Abstract: Systems and methods address automated temporally based configuration management of a procurement/deployment process that may be used at one or more data centers. A set of current configuration attributes and current parameter settings are maintained for a one or more data centers. Information may be obtained from a purchasing system describing a future device. Prior to actual arrival of the future device, the configuration for that future device may be defined. Upon detection of the uniquely identified future device being communicatively coupled to a management network, the previously defined configuration may be applied. Abstraction from a high-level to vendor specific configuration commands may also be incorporated to allow management of devices from multiple vendors.

Abstract: A head mounted display including a main body, a sound controller, a vibration driver, a motion sensor, a vibrator and a speaker is provided. The main body has a display device. The sound controller is electrically connected to the main body. The vibration driver is electrically connected to the sound controller. The motion sensor is configured to sense a motion state of the main body. The vibrator is electrically connected to the vibration driver. The vibration driver receives a vibration signal from the sound controller, adjusts the vibration signal as needed according to the motion state and then drives the vibrator to generate vibration by the vibration signal. The speaker is electrically connected to the sound controller. The speaker outputs a sound according to a sound signal received from the sound controller. A driving method of a head mounted display is also provided.

Abstract: An audio modification includes a signal transmitter, at least one signal receiver, a processor and an audio generator. The signal transmitter being disposed on a first device is configured to transmit a signal. The at least one signal receiver being disposed on a second device is configured to receive the signal. The processor is configured to determine a first distance between the first device and the second device according to a measuring indicator of the signal and to calculate a second distance that forms a head dimension of a user. The processor is further configured to apply the head dimension in a head related transfer function in order to modify audio information. The audio generator is configured to output a sound corresponding to the audio information.

Abstract: In some examples, a method includes constructing, by a computing device, a plurality of expressions using a generic query language that is independent of implementation of an associated data store, the associated data store supporting a plurality of operands comprising at least one comparison operand and multiple logical operands; generating, by the computing device, a single query including the plurality of expressions to the associated data store, wherein the plurality of expressions are connected using the multiple logical operands; transmitting, by the computing device, the single query to the associated data store; and receiving, by the computing device, a single set of results corresponding to the single query.

Abstract: In some embodiments, an apparatus includes a first controller configured to be operatively coupled within a network having a set of network nodes, a forwarding gateway and a configuration entity. The first controller is configured to manage session state and node state associated with the set of network nodes independent of the forwarding gateway. The first controller is configured to fail over to a second controller when the first controller fails, without the forwarding gateway failing over and without the configuration entity failing over.

Abstract: In some embodiments, an apparatus comprises of a control module implemented in at least one of a memory or a processing device that is configured to receive, via a network and from a wireless access point or an access network node, a control packet defined based on a control protocol. The control packet is associated with at least one control function of the wireless access point or access network node. The control module is configured to determine a status of an access network node based on the control packet from the access network node. The control module is configured to send via the network, a response to the access network node based on the status of the access network node.

Abstract: In some embodiments, an apparatus comprises of a first Control And Provisioning of Wireless Access Points (CAPWAP) module implemented in at least one of a memory or a processing device that is configured to be designated as a backup control module for a wireless access point during a first time period.
