  • Patent number: 11463425
    Abstract: Traffic broadcast to a VLAN is restricted. To do so, a plurality of stations are associated with a BSSID (basic service set identifier). A first VLAN is configured by sending a first group key to each station from the plurality of stations that is a member of the first VLAN, wherein each VLAN is associated with a unique group key. One or more frames addressed to the first VLAN are received. The one or more frames are encrypted with the first group key to prevent stations without the first group key from being able to decrypt the one or more frames. The one or more encrypted VLAN frames are broadcast to the plurality of stations associated with the BSSID.

  • Patent number: 11083116
    Abstract: The present disclosure relates to a cooler and to a display device having the same, where a heat-exchanger of the cooler is arranged on a side surface of a display unit in order to simplify the structure and to make a slimmer display device. The cooler includes a closed air circulation pathway circulating between the front, rear and sides of the display unit; an open air flow pathway that flows in the length direction of the side of the display unit; and a cooling module that is installed on the side of the display along the length direction of the display, and that includes the heat-exchanger, where the closed air circulation path and the open air flow part are adjacent, thereby causing heat-exchange.

  • Publication number: 20210166237
    Abstract: Raw merchant data of real-time ISO transactions is enriched with normalized merchant data, including a normalized merchant name, a normalized merchant location, by transmitting the raw merchant data to an external resource and receiving the normalized raw merchant data from the external resource. An authorization request from a real-time ISO transaction concerning a specific mobile user can be initiated by a specific merchant device at a merchant location. A user location is obtained and utilized to identify enriched merchant data. It is the enriched merchant data that is used for deciding whether to approve or deny a transaction with more accuracy.

  • Patent number: 10905036
    Abstract: The present invention relates to: a cooler capable of simplifying a structure, increasing heat exchange efficiency, and slimming a display device; and a display device using the same. A cooler structure applied to the display device uses a heat pipe allowing a refrigerant, which is a volatile liquid, to flow therein and a fin structure expanding a heat transfer cross section, so as to rapidly absorb, through evaporation of the refrigerant, heat from the air in a closed air circulation path circulating around a display unit, and quickly dissipate heat from an outside space (an open air circulation path) of the closed air circulation path through condensation of the refrigerant, thereby enabling heat exchange to occur very efficiently while occupying less volume. Additionally, the present invention provides the cooler structure in which the heat pipe is made in a circular fashion such that the refrigerant efficiently flows therein.

  • Patent number: 10880749
    Abstract: Techniques which prevent rogue devices from continued access to a wireless communication system. A control element directs access points as to which mobile stations to service. Each access point maintains a record of the mobile stations it is servicing. At the direction of the control element, one or more access points send ACK (acknowledgement) messages when hearing messages from a rogue device. When the rogue device sends a message, it expects an ACK message in response, but those additional ACK messages interfere with the responsive ACK message, causing the rogue device to never hear the responsive ACK message. The rogue device assumes its message was not received, so it retries sending of that message. When the rogue device retries sending of its message, the responsive ACK message is similarly interfered with, until the rogue device concludes that its connection has been lost.

  • Patent number: 10652905
    Abstract: Network devices are steered to preferred access points using a probability function. A probe request for connection is received from a network device. The probe request can be from a network device attempting to use a wireless network (e.g., a IEEE 802.11-type network or other suitable type of network). A probability function that defines a likelihood of granting the network device a connection is used to determine whether to accept or deny the response. The probe response is then sent to the network device.

  • Publication number: 20200113208
    Abstract: Provided are a method of concentrating protein in grain powder, grain powder including protein that has been concentrated by using the method, and a feed additive including the grain powder including concentrated protein. According to the method of concentrating protein in grain powder, grain powder is treated with enzyme to increase the water-soluble saccharide content in a source, and by inoculating bacteria or yeast and fermentation, the increased water-soluble saccharide is removed, leading to a higher concentration of protein. Thus, the protein content ratio increase effects and the function of grain powder as a protein source are enhanced.

  • Patent number: 10341920
    Abstract: Data distribution between mobile stations and external data paths is assigned to a new set of devices, distribution points. Each distribution point is independently coupled to mobile stations, also assigned to access points. Control elements operate to control the distribution points separately from the access points. Each access point maintains a substantially stateless link with each distribution point for which the two share a mobile station. Access points might exchange data with any one or more distribution points concurrently. Access points thus obtain greater bandwidth connectivity to external data paths. Mobile stations transfer between access points and transfer between distribution points independently. This has the effect that bandwidth connectivity between distribution points and external data paths have no particular requirement for VLAN separation. Mobile stations may roam among multiple Internet protocol subnets.

  • Patent number: 10327186
    Abstract: A technique for providing per station control of multiple stations in a wireless network across multiple access points. A look-up table that assigns a station connected to the access point and at least one communication parameter to each of a plurality of persistent, uniquely-assigned BSSIDs (Basic Service Set Identifiers) is stored. An access point responds to messages addressed one of the plurality of persistent, uniquely-assigned BSSIDs and ignores messages addressed to other BSSIDs. Persistence of the BSSID allows the controller to maintain individual control over each station after moving to a second access point of the plurality of access points. A frame comprising the plurality of BSSIDs corresponding to each connected station aggregated into the frame is generated. The frame is transmitted to the plurality of stations.

  • Patent number: 10278105
    Abstract: AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.

  • Patent number: 10225764
    Abstract: Uplink medium access control on per-wireless device level for a specific user. An access point sends a beacon frame to a wireless device. The beacon frame includes a BSSID that is unique to the wireless device. The beacon frame also includes embedded uplink configurations specifying uplink medium access for the wireless device. In one embodiment, a controller recognizes a device or user associated with the device, and sends corresponding uplink configurations for embedding in a subsequent beacon frame.
