Abstract: Systems and methods for selecting, sequencing, and presenting traffic events to viewers. This may involve using a prioritizing scheme that estimates the proximity or relevance of the event to the viewers by associating the event with a geographic zone and the viewer with a localized service area served by a particular distribution points of the television content distribution system. In some cases, for each localized service area, zones are given priority values that are used when prioritizing the relevance of traffic events associated with those zones. For viewers in a given localized service area, a first zone may have a higher priority than a second zone, such that in prioritizing traffic events, events associated with the first zone are given a higher priority than events occurring in the second zone. Different zone priority schemes may be associated with a given localized service area at different times of day, week, or year.

Abstract: A portable alarm consists of a unit which emits an alarm signal when it is tilted to a predetermined extent from its upright position, and having a base support which will support the unit in a condition of unstable equilibrium, and a stay which, when the unit is stood substantially upright near to a door, for example, may be rested against the door to impart stability to the unit, which will fall from the upright position and emit the alarm signal if the door is opened to move the stay.

Abstract: An exterior rear vision mirror for a vehicle is rotated about its axis, within its housing, by an electric motor, and is restrained from significant vibration by a flexible drive from the motor to the center of the mirror, and by stabilizer ring coaxial with the mirror and pressing against it to maintain it in the desired plane. In wet conditions, rain drops are thrown centrifugally from the mirror, keeping it clear. In dry conditions, the mirror may be cleaned of dust by water directed from a nozzle onto the central part of the rotating mirror.
