A system and method of determining data latency in a network is provided. A first data sample of application level data (e.g., financial data) is provided from a data stream received at a first network point. A second data sample of application level data (e.g., financial data) is also provided from a data stream received at a second network point, where the data streams in the first and second ne...

A portable device for preventing communication errors caused by disturbance such as noise. The portable device receives a first request signal from a communication controller and transmits a first response signal corresponding to the first request signal. A transmitter transmits the first response signal with a selected one of a plurality of frequencies. A transmission control unit transmits the f...

An apparatus for drawing a flexible cord into a wrapped configuration around a reel. The apparatus has a housing and a reel that is movable around a first axis relative to the housing. The apparatus further includes a spring system through which a rotational force is exerted on the reel tending to rotate the reel around the first axis to thereby cause a flexible cord associated with the reel, that...

The invention relates to a sound dampening housing for a rock drill which moves along a feed beam in a longitudinal direction thereof, the sound dampening housing being attachable to the feed beam of the rock drill on its both sides so that together with the feed beam the sound dampening housing constitutes a substantially closed space. The sound dampening housing is double-shelled, and an airspac...

The invention relates to a shield structure of a rock drilling apparatus for dampening noise, the rock drilling apparatus comprising a feed beam whose one end is a drilling end, whereby the drilling end of the feed beam comprises a first shield part mounted immovably relative to the feed beam, and a second shield part mounted movably relative to the feed beam. A tubular shield flexible at least in...

A method of operating an ad-hoc network having a plurality of wireless nodes includes operating the wireless nodes using a routing protocol, such as OLSR, so that the wireless nodes store forward multi-point relay (MPR) spanning tree routes and reverse MPR spanning tree routes. A first wireless node communicates with a second wireless node using a reverse MPR spanning tree route. The method furthe...
