Abstract: A range animal injection apparatus has a syringe, a pressure chamber, a needle and a self-removal system which may include a contact member positioned only on one side of the needle and projections extending from an end of the dart. When the apparatus hits an animal the contact member is pushed back opening a valve at the needle end of the syringe. Pressure in the pressure chamber acts on the plunger of the syringe pushing medication into the animal. The plunger eventually closes the valve and moves the contact member forward to remove the apparatus from the animal. Pinching is reduced by the contact member being positioned below and not around the needle. The projections help keep the dart relatively perpendicular to the hide reducing pinching and increasing leverage. The projections also reduce rotation of the apparatus, helping to keep the contact member below the needle.

Abstract: Disclosed is a feature for a vehicle that enables taking precautionary actions in response to conditions on the road network around or ahead of the vehicle. A database that represents the road network is used to determine locations where a potentially hazardous condition exists. Then, precautionary action data is added to the database to indicate a location at which a precautionary action is to be taken relating to the hazardous condition. A precautionary action system installed in a vehicle uses this database, or a database derived therefrom, in combination with a positioning system to determine when the vehicle is at a location that corresponds to the location of a precautionary action. When the vehicle is at such a location, a precautionary action is taken by a vehicle system as the vehicle is approaching the location where the potentially hazardous condition exists.
