  • Publication number: 20240085867
    Abstract: A static auto-tuning system and method for controlling operation of a motor in a system. A speed reference signal is generated resulting in a speed response of the motor. Closed-loop feedback magnifies the rotating friction effect to an observable level. Inertia and rotating friction coefficient values of the system are estimated based on the speed frequency response and a virtual damping coefficient. A fixed low frequency speed signal may result in a first frequency response function for determining virtual damping, and a variable frequency excitation signal may result in a second frequency response function for determining the inertia and rotating friction characteristics. Closed-loop gains are determined based on these characteristics. The excitation signal may be sampled and a peak value in each interval may be identified and stored to produce an envelope of peak values for determining the gain response. Operation of the motor is controlled using the determined gains.

  • Patent number: 11831519
    Abstract: Techniques are described by which a network management system (NMS) provides a common user interface (UI) to enable a user to collectively configure network devices to establish an EVPN topology. For example, an NMS is configured to: generate data representative of a common UI comprising UI elements representing a plurality of network devices to be configured in an EVPN topology; receive, via the common UI, an indication of a user input selecting one or more of the UI elements representing selected network devices; generate UI elements representing a plurality of ports of the selected network devices; receive, via the common UI, an indication of a user input selecting the UI elements representing one or more selected ports; and generate, based on the one or more selected network devices and one or more selected ports, topology relationship information of the one or more selected devices to establish the EVPN topology.

  • Publication number: 20220417742
    Abstract: Techniques are described that enable onboarding of a plurality of heterogeneous client devices with secure access to a wireless network using a network management system (NMS). The NMS has a memory to store a plurality of private pre-shared keys (PPSKs), where each PPSK is provisioned for a particular client device or a particular group of client devices. In response to a key lookup request from an access point (AP) device for a client device, the NMS performs a key lookup and, in response to identifying a PPSK provisioned for the client device, authenticates the client device to access the wireless network via the AP device. The NMS then manages one or more of tracking the client device, policy application to the client device, or handling of network traffic from the client device while connected to the wireless network using the PPSK as an identifier of the client device.

  • Patent number: 10165477
    Abstract: One embodiment of the present invention provides a system for configuring an access point in a wireless network. During operation, the access point discovers one or more existing access points associated with the wireless network. The access point then obtains a set of configuration information from one existing access point, and synchronizes a local timestamp counter to a selected existing access point, thereby allowing the access point to be configured without using a centralized management station.

  • Patent number: 9531550
    Abstract: A PoE-enabled wireless device facilitates providing wireless access to a local area network (LAN) by receiving power from an Ethernet cable. The device includes a first Ethernet port that can receive a power signal. The device also includes a second Ethernet port that facilitates coupling the apparatus to the LAN, and includes a wireless module to provide a wireless network connection to the LAN. Specifically, the wireless module receives power from the power signal of the first Ethernet port to provide the wireless network connection. The wireless device can also include a third Ethernet port for providing power and a network connection to a remote network device. The wireless device can use the third Ethernet port to send an external-reset signal to the remote network device, which facilitates remotely resetting a configuration of the remote network device without having to physically access the remote network device.

  • Patent number: 9131378
    Abstract: Systems and methods for authentication using paired dynamic secrets in secured wireless networks are provided. Each authenticated user is assigned a random secret generated so as to be unique to the user. The secret is associated with a wireless interface belonging to the user, so that no other wireless interface may use the same secret to access the network. The secret may be updated either periodically or at the request of a network administrator, and reauthentication of the wireless network may be required.

  • Patent number: RE48821
    Abstract: Apparatus and methods are provided for protecting network resources, particularly in association with automatic provisioning of new client devices. A global PKI (Public Key Infrastructure) scheme is rooted at a globally available server. Roots of PKIs for individual organizations also reside at this server or another globally available resource. To enable access to an organization's network, one or more authenticators are deployed, which may be co-located with access points or other network components. After a client device enabler (CDE) and an authenticator perform mutual authentication with certificates issued within the global PKI, the CDE is used to provision a new client device for the organization. After the client is provisioned, it and an authenticator use certificates issued within the per-organization PKI to allow the client access to the network.
