  • Patent number: 12231337
    Abstract: Optimized routing in localized dense networks is provided. A packet is received at a first network device in a network. An optimal route for the packet to a neighbor network device in the network is determined using a Source Routing Table (SRT), wherein the SRT includes an optimized routing table and a standard routing table, and wherein the optimized routing table comprises a list of neighbor network devices that the first network device can route to directly and wherein the standard routing table comprises a ZigBee source routing table. The packet is routed using the optimal route.

  • Patent number: 12108266
    Abstract: Methods and system to determine the health of wireless mesh networks are provided. Each radio node of a wireless mesh network transmits Link Quantification Messages (LQMs) interPAN at maximum power to enable adjacent nodes to determine the Received Signal Strength Indication (RSSI) on the wireless link to that radio node. Each radio node also transmits LQMs at successively lower power levels. The adjacent nodes detect a power level at measurable packet error rate to determine a noise floor for the wireless link. An aggregator collects link quantification information from the radio nodes and forms an intercommunication matrix for the wireless network. The RSSI and power level at measurable packet error rate information is used to remove unreliable links from the intercommunication matrix. Nodes are ranked and the reliability and dependability of the nodes is calculated to show the network health.

  • Patent number: 9917398
    Abstract: A connector assembly includes a first component having a slot and an indentation and a second component having a hook and a protrusion. The hook is configured to engage with the slot by being inserted into the slot and being translated with respect to the slot. The protrusion is configured to at least partially depress as the hook is inserted into the slot and engage with the indentation when the hook is positioned to engage with the slot. The hook and the slot, when engaged, resist separation of the second component from the first component. The protrusion and the indentation, when engaged, resist disengagement of the hook from the slot.

  • Patent number: 8959427
    Abstract: The disclosure describes exemplary methods and systems for building search-friendly websites from templates on a browser based or web-enabled stand-alone website builder application. The website builder application is an HTML page with JavaScript function calls and HTML content blocks enclosed with JavaScript functions. Each HTML content block includes HTML content and HTML IDs. The HTML page includes style scripts that update to reflect retailer implemented template property changes. When the user chooses a different layout for the website template, inputs to a JavaScript moving function in the form of HTML IDs of the origin HTML content and a destination HTML content block cause the JavaScript moving function to re-write the HTML content of the origin HTML content block to the destination HTML content block. The JavaScript moving function removes the origin HTML content block. The CSS styling from the destination HTML content block automatically applies to the static HTML content.
