Abstract: One or more techniques and/or systems are disclosed for alerting workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a detection unit operable to mount to a work zone boundary marker. The detection unit can monitor the work zone for intrusion by moving objects, such as by using the Doppler Effect. The detection unit can transmit an alarm signal to one or more personnel alerters, such as worn by workers. The personnel alerters can receive the alarm signal and activate an alert, such as an audible, visual, or other sensory alert. In this way, an alert is provided to personnel working in an established work zone that a moving object, such as a vehicle, has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.

Abstract: One or more techniques and/or systems are disclosed for warning workers in a work zone of a potential intrusion by a vehicle. The example system can comprise a master device, coupled with one or more boundary markers using a tripwire. When the trip wire, and/or one of the boundary markers, is impacted with sufficient force, the tripwire is disengaged from the master device. Once disengaged, the master device can transmit a wireless alert signal to one or more portable alerter, such as worn by workers. The portable alerters can receive the signal and activate a personnel alert, such as an audible, visual, or other sensory alert. In this way, an alert is provided to personnel working in an established work zone that a potentially threatening vehicle has penetrated the work zone perimeter. This type of alert may provide the personnel the vital seconds needed to move to safety.

Abstract: A method and system for information collation through software code by a digital computer. The software code includes a collator. The collator receives first update information from a first user for updating a first topic portion of a first document with the first update information. The first topic portion has an associated first topic identified by a first topic identifier assigned to the first topic by a first template that the first document conforms to. The collator updates the first topic portion of the first document with the first update information based on the collator having determined that the first user has been assigned a project identifier that matches the project identifier of the project and that the first user has been assigned a topic identifier that matches the first topic identifier, which confirms the first user's authorization to have the first document updated with the first update information.

Abstract: In a method for an alerting system for travelers, a processing center receives travel itinerary information from a subscriber. The travel itinerary information includes a destination arrival time. The processing center sends a processor message to a recipient other than the subscriber when a cancellation message is not received from the subscriber prior to a predetermined period of time after the destination arrival time. The processor message includes a portion of the travel itinerary information.

Abstract: A composition useful for the surface treatment of copper, in particular for micro-roughening of the copper surface so as to improve the adhesion characteristics of the copper surface, comprises an oxidizing agent for copper and an aromatic sulfonic acid or a salt thereof. In a preferred embodiment, the oxidizing agent is hydrogen peroxide and the aromatic sulfonic acid is sodium m-nitrobenzenesulfonate. The composition preferably also includes an inorganic acid such as sulfuric acid and a corrosion inhibitor such as benzotriazole.

Abstract: By using as the lightweight aggregate, in the manufacture of lightweight concrete, polystyrene-bead materials of particularly controlled characteristics in regard to bead size and coefficient of variation of absolute volume, there is obtained a substantial improvement in regard to the accuracy with which the density of the product lightweight concrete can be controlled or preordained. Since the strength and insulation-value properties are closely related to the density, the improvement aids in the design and production of more economical parts.
