Abstract: A vehicle detection system warns snowmobilers of other approaching vehicles with potential risk of collision. To better prevent accidents, the system calculates collision risks and warns the rider based on level of risk. When riding in groups, a member can press a stop request button to ask the group to slow down. When a member exits the group, everyone in the group will receive a message, alerts or indication with the update. The vehicle detection system utilizes Bluetooth® low energy (BLE), LoRaWAN® technologies and/or global positioning system technologies and is designed to detect other devices in the region and use acquired information to calculate proximity and risk of collision.

Abstract: A door stay for attachment to a door above a floor, the door stay comprising a mounting means, and a floor-contacting element rotatably mounted on said mounting means, the floor-contacting element being biased against said floor by the mounting means. Preferably, the floor-contacting element is a ball and the ball moves over the floor under tension. The door stay provides significant advantages in the positioning of a door so that it will not swing to and fro, but which can still nevertheless be swung open when desired by manual operation of the door. The door stay is attachable to the lower edge of the door, wherever required and removed when no longer required, or when it is required somewhere else. All of these features are provided in a relatively simple low cost door stay which is highly effective in practical use.

Abstract: A paint bucket has a preferably removable divider, the divider having a magnet positioned such that at least two paint brushes can be held by it, at least one on each side of the divider. Preferably, at least a portion of the divider is a grid for wiping excess paint off a brush in use. A paint tray has spaced-apart male and female connections, such that when one said liner is inverted over another liner, the liners mate with each other via the male and female connection means, the respective connection means of one liner mating with the opposite connection means of the other liner.

Abstract: The device is an improved knife blade container comprising a lid portion and a container portion. The container portion comprising at least two compartments the first compartment for storing new knife blades and the second compartment for storing used discarded knife blades. The lid portion encloses the container portion such that the items stored within each of the separated compartments can remain separated.
