  • Publication number: 20230337400
    Abstract: A new approach is proposed to support fan-less thermal mitigation for an industrial-grade appliance. The industrial-grade appliance may comprise a plurality of hardware components that are major sources/regions of heat production in the industrial-grade appliance. Under the proposed approach, a heatsink is included in the industrial-grade appliance to address heat dissipation for all of the major sources/regions of heat production positioned on a main board of the industrial-grade appliance. The heatsink is specifically designed to have a plurality of surfaces that are in contact with all of the major heat-producing components of the industrial-grade appliance, wherein each of the plurality of surfaces of the heatsink has a maximum overlapping surface area with at least one of the major heat-producing components in order to transfer maximum amount of heat through conduction. Under the proposed approach, the heatsink is fan-less wherein no fan is used for heat dissipation.

  • Patent number: 10439990
    Abstract: An approach is proposed that contemplates system and method to configure firewall rules of a VPN gateway of a protected network so that users of devices in the protected network can access Internet securely via a captive network. First, the proposed approach enables the VPN gateway to probe the captive network with an HTTP request to discover a captive portal of the captive network. After the captive portal is discovered, one or more firewall rules of the VPN gateway are added so that network traffic from the devices in the protected network are redirected to the captive portal for authentication. Once the users are authenticated and a VPN tunnel is established between the VPN gateway and a remote VPN tunnel terminal, the firewall rules previously added are removed from the VPN gateway and all network traffic from the devices in the protected network are routed over the VPN tunnel.

  • Publication number: 20140254100
    Abstract: A desktop enclosure provides cooling for a circuit board without the noise and power consumption of fans. An elastomeric suspension applies a force to a circuit board. The circuit board transmits the force to a heat source which is thermally coupled to a heat conduction rod through a non curing, ultra-high conductive performance thermal interface grease. The heat conduction rod is fastened to a heatsink lid of the enclosure which dissipates the heat by convection and radiation.

  • Patent number: 6422608
    Abstract: An anti-abrasion pipe fitting for high speed particle-laden flow is disclosed, which includes a plurality of flow fields such as a vortex flow field formed at a flow direction changing portion during a fluid feed by expanding an outer side curved portion and inner side curved portion of the flow direction changing portion to the outside of a standard flow range in an elbow shaped curved coupling pipe formed of an upper side straight portion, a lower side straight portion perpendicular to the upper side straight portion, and a flow direction changing portion formed between the upper side straight portion and the lower side straight portion, so that it is possible to prevent an abrasion at a portion in which a flow direction is changed without forming a protection film formed of an anti-abrasive material at an inner wall of a pipe for thereby increasing the life span of the system.
