Abstract: Online retailers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may include queries requesting market data corresponding to items offered for sale on an electronic commerce website operated by the online retailer. The response to the queries may be stored by one or more services of the online retailer and used as market data for the electronic commerce website. The market data may be used to notify customers about one or more items offered for sale on the electronic commerce website.

Abstract: Fasteners such as clip nut fasteners can include a clip having a nut cage and a nut supported by the nut cage. The nut cage can have a wall supporting a portion of the nut wherein the wall can flex toward and away from the nut. The nut can have projections or other discontinuities for engaging bearing surfaces in the nut cage, for limiting rotation of the nut when under torque.

Abstract: A fiber sealing apparatus in which a seal about an outer fiber optic cable may be formed relatively independently of a seal about an inner fiber optic line. The fiber optic sealing apparatus may comprise a housing containing a central passageway there through. The housing may further comprise a fiber seal and a seal energizer configured to interact with the fiber seal. An intermediate cap may be coupled with an end of the housing and configured to apply a load to the seal energizer. An end cap may be coupled with an end of the intermediate cap and configured to seal against an inserted fiber optic cable. Applying the load to the seal energizer may result in a barrier forming around an inserted fiber optic line.
