US Classification:

Abstract:

A method and system for determining whether an IP address is part of a bot-network are provided. The IP-address-aggregate associated with the IP address of an e-mail sender is determined. The IP-address-aggregate is associated with an IP-address-aggregate-category based on the current SMTP traffic characteristics of the IP-address-aggregate and the known SMTP traffic characteristics of an IP-address-aggregate-category. A bot-likelihood score of the IP-address-aggregate-category is then associated with IP-address-aggregate. IP-address-aggregate-categories can be established based on historical SMTP traffic characteristics of the IP-address-aggregates. The IP-address-aggregates are grouped based on SMTP characteristics, and the IP-address-aggregate-categories are defined based on a selection of IP-address-aggregates with similar SMTP traffic characteristics that are diagnostic of spam bots vs. non-botnet-controllers spammers. Bot likelihood scores are determined for the resulting IP-address-aggregate-categories based on historically known bot IP addresses.

Abstract:

An emergency spinal immobilization and extrication device permits a victim of spinal column trauma to be firmly supported and immobilized for transportation to a health care facility. The device comprises a container filled with a multiplicity of small, resilient particles resting on a light-weight, rigid base-board, and having a sliding rigid cover. The container comprises means for inflating with gas and deflating. In operation the victim is placed on the cover and restrained at the ankles. As the cover is removed by sliding, the victim descends onto the container. The container is then deflated, leaving the victim supported by the particles which cling together as the gas is evacuated.
