Abstract: The test packet sequencer according to the present invention, is configured to generate one or more sequences of packets and subsequently place these one or more sequences of packets onto a communication network. The test packet sequencer is further configured to measure timings associated with the one or more sequences of packets. For example, the test packet sequencer can be configured to measure the departure and/or receipt times of one or more sequences of packets. In order to overcome inherent delays or inaccuracies relating to the functionality of one or more components along the network path, the test packet sequencer is configured to pre-activate at least a portion of the network path prior to placement of the one or more sequences of packets on the communication network.

Abstract: An all weather hood with adjustable cuff openings around each ear to accommodate earmuffs designed to provide hearing protection. Earmuffs are put on first, then the hood is pulled on over them and the ear cuffs are adjusted snugly around each earmuff. Also acts as a liner for safety helmets with attached hearing protection earmuffs. The helmet is worn over the hood, then the earmuffs are pulled down passing through the hood ear cuff openings to be placed directly over the ears. The hood ear cuffs are then adjusted snugly around each earmuff. Provides superior hearing protection compared to liners worn under hearing protection earmuffs and provides superior weather protection compared to liners worn over hearing protection earmuffs. The hood, when combined with a safety helmet having attached hearing protection earmuffs, work together as a single unit of personal protection equipment (PPE), for simple and efficient operation.
