Abstract: There is disclosed a telemetry monitoring apparatus for remotely monitoring a plurality of users, such as firefighters, working in a hazardous environment. The apparatus comprises a plurality of portable devices, each arranged to be associated with breathing apparatus worn by a user, and at least one central monitoring station onto which portable devices can be logged on and monitored. The portable devices are arranged to transmit a logon message including an identifier identifying either the user or the portable device.

Abstract: There is disclosed a telemetry monitoring system including a central monitoring unit configured to display data regarding one or more portable devices, each associated with the breathing apparatus of a user. The system further includes removable data storage connected to the central monitoring unit and configured to store system status data of the central monitoring unit as recovery data, the system status data defining an operational status of the central monitoring unit. In the event of a failure of the telemetry monitoring system, the telemetry monitoring system can be recovered by restoring the recovery data to the central monitoring unit or a replacement central monitoring unit from the removable data storage.

Abstract: A method and composition for reducing hydrogen sulfide generated or emitted from an asphalt composition are disclosed. In certain aspects, a method for reducing hydrogen sulfide emissions from an asphalt composition is provided wherein an additive is mixed with the asphalt composition and the additive is a copper-based complex. The asphalt composition can include asphalt and an asphalt modifying acid. The copper-based complex can comprise copper carboxylate. The copper carboxylate can be an oil-soluble metal organic.

Abstract: Methods for isolating viable cancer cells from a sample that comprises a mixture of cancerous cells and normal (non-cancerous) cells are provided. In the methods, a fluid preparation comprising a mixture of cancerous and normal cells is repeatedly exposed to fluid shear stresses, whereby the repeated exposure to the fluid shear stresses preferentially imparts fluid shear stress-resistance to the cancerous cells.

Abstract: Apparatus and associated methods may relate to a unitary body having a hardness of between 20 and 35 according to the Japanese Industrial Standards (JIS) and adapted to be removably inserted into the canal 10 of an ear. In an illustrative example, the body may include a central portion between an adapter portion disposed at the proximal end of the body to couple an audio signal from an audio signal source to the central lumen. The retention portion may be disposed at a distal end of the body along a distal end axis. When inserted in the ear canal, the retention portion may be adapted to engage the canal wall between a prominence and the eardrum membrane with comfort for extended periods of time, including during physical activities, without falling out of the ear. Some embodiments by be packaged as a kit containing pairs in a range of predetermined sizes.
