Display cooler and display device using same
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. Particularly, when a section in which the heat pipe generates heat is disposed on the side of the display unit, the display device can be formed to be just as slim. |

Overvoltage detection circuit with first and longer second response times
A light emitting diode system allows for high current end user LED matrix applications while mitigating internal damage to control circuitry that may be caused by excess current flow. In one example, multiple switches operate in parallel across an LED. When an overvoltage condition is detected in a first switch, a logic circuit determines those switches programmed to operate in parallel and causes them to conduct current. This reduces the amount of current flowing through any one switch and mitigates harm to the device. The parallel configuration of switches may be driven by a single pulse width modulated current. This allows the drive current to be divided between parallel transistors, limiting the damaging effects that can be caused by high currents flowing through the transistors. |

Techniques for providing full-featured browser access during captive portal authentication routines
The present disclosure is generally directed to a method and system for authentication with a computer network that comports with CNA requirements, but utilizes a bypass approach that allows for authentication to be completed within a full-featured browser. In an embodiment, an access point (AP) may be configured to allow for user devices to associate and detect the presence of a captive portal. However, during the CNA messaging sequence, the AP can provide a CNA bypass message that causes the CNA browser instantiated on the user device to consider the authentication complete without having to satisfy authentication requirements. Based on the CNA bypass message, the user device may then transition to a full-featured browser to complete authentication via a captive portal. Authentication may be completed by, for example, watching at least a portion of a video, playing a video game, taking a quiz, and/or entering identifying information. |

Database firewall for use by an application using a database connection pool
An application server environment that uses connection pooling is augmented to include a database access control system having a database firewall. When the database firewall detects a security violation with respect to a request received via a pooled connection, the firewall skips over (i.e. do not forward) the violating request and instead creates an artificial error database protocol packet corresponding to the application request. The database firewall then sends the error database protocol packet as a response back to the application, using the pool connection. The application receives the database error as a response to the security violating request, and it responds by releasing the connection of the policy violation database user. By releasing the pool connection is this manner, the performance of other applications (or other clients) using the connection pool is not impacted. Preferably, the error packets include no sensitive information. |

Intelligently routing a response packet along a same connection as a request packet
A first edge server of multiple edge servers of a distributed edge computing network receives a request from a client device regarding a resource hosted at an origin server according to an anycast implementation. The first edge server modifies the request to include identifying information for the first edge server prior to sending the request to the origin server. The origin server responds with a response packet that includes the identifying information of the first edge server. Instead of routing the response packet to the client device directly, one of the multiple edge servers receives the response packet due to the edge servers each having the same anycast address. If the edge server that receives the response packet is not the first edge server, that edge server transmits the response packet to the first edge server, who processes the response packet and transmits the response packet to the client device. |
