Abstract: Air purification devices are described. Devices are powered to form an electric field along an airflow path that creates a plasma for destruction of pathogens carried through the device. Devices can be single-user, portable devices for purification of air flow to and/or from a single user.

Abstract: Embodiments are directed toward transparent denial of service protection. Instruction set information that references a seed file may be communicated to a client computer. A network packet key may be generated based on the instruction set information or encrypted and provided by a server. A client computer may generate a client network packet key based on the instruction set information provided by the network computer and a seed file installed on the client computer. The client computer may include the client network packet key the one or more network packets that it is sending to the network computer before they are provided to the network computer. A packet rule that includes the network packet key may be generated and installed in a packet inspection engine. If network packets are received, the packet inspection engine compares the network packet key to the network packets using the packet rule.

Abstract: A security management system can log, investigate, respond, and track computer security incidents that can occur in a networked computer system. In other words, the security management system can produce a security record of information related to the tracking of suspicious computer activity or actual computer security threats, such as denial of service attacks or other similar compromises to computers or computer networks. The security record can include, but is not limited to, date and times of computer security incidents, a name for a particular security incident, a security management system user, and a potential source of the computer security incident. The security record can be designed as a running log that saves or records all activity of a computer incident source as well as the activity of the security team responding to the computer incident source.

Abstract: An apparatus includes a wireless device having a radio frequency (RF) circuit, an omni-directional antenna coupled to the RF circuit, a directional antenna coupled to the RF circuit, and a switch configured to couple at least one of the omni-directional antenna and the directional antenna to an output of the RF circuit.

Abstract: A computerized method for modifying an optical wavelength division multiplexing (WDM) network is described. The method includes providing an initial configuration of the optical WDM network. At least one parameter that represents a characteristic of a span in the optical WDM network as defined by the initial configuration is evaluated. The initial configuration of the optical WDM network is modified in response to the evaluation. The method can also include determining if a predetermined set of engineering rules are satisfied.
