Abstract: A portable signaling device and method of use in which an elongated reflected strip with a broad and flat profile is held taut in air so that the elongated reflective strip freely twists and rotates along a line formed between a first and a second attachment point of the composite strip when a breeze contacts the broad and flat profile to create a visual signaling display as a result of twisting and rotation of the elongated reflective strip.

Abstract: The fuel control routine of an engine control module sets a cold enrichment schedule used for engine starting when the engine is cold. The enrichment value is dependent on coolant temperature. To prevent plug fouling in a new vehicle subject to short engine run times, the enrichment value is reduced if the mileage is below 50 miles, the coolant temperature is within set limits and the previous engine run time was shorter than a set period.

Abstract: Apparatus for piercing the earlobe to produce an opening for the wearing of earrings. A relatively movable anvil and carriage are provided. The carriage mounts a precompressed spring, bearing against a piercing dart. A spring housing and barrel on the carriage are also relatively movable. The earlobe is placed between the anvil and carriage and the carriage moved into engagement with the earlobe. Further pressure on the carriage produces relative movement between the spring housing and barrel and this relative movement causes dual triggers to be cammed out of engagement with the piercing dart. The movement of the triggers releases the dart which pierces the earlobe and is guided into a catch button on the anvil. A catch spring engages the shaft of the piercing dart and holds the parts in association so that the body portion of the apparatus may be removed.
