Abstract: Aspects of disclosure provide a system for reducing traction of a vehicle. The system includes a mobile controller, and a remote controller. The mobile controller is configured to control release of a liquid. The mobile controller corresponds to a vehicle and configured to direct the release of the liquid to specified wheels of the vehicle. The remote controller is in wireless communication with the mobile controller. The remote controller is configured to store a liquid release setting for the mobile controller, to receive a selection of the vehicle, and to issue a liquid release command including the liquid release setting to the mobile controller corresponding to the selected vehicle. The mobile controller corresponding to the selected vehicle is configured to initiate a release of the liquid directed to one or more wheels of the selected vehicle to reduce traction of the selected vehicle according to the liquid release setting.

Abstract: A peep site as a sighting mechanism for an archery bow and arrow slidably mounts on an archery bow string. The peep site is self-aligning with an elastic string anchored between the peep site and an archery bow that pulls the peep site forward toward the bow when the bow string is stretched. The mount has a slot between the hole on one mount end and the other mount end to which the elastic string attaches. To install the mount the bow string is inserted through the slot and into the hole. The slot is then closed, either by one end of the elastic string looped around the mount or by a plug secured to the mount. A member with a peep hole extends from the mount such that when the mount is forward aligned and located on the bow string at a preferred position, the peep hole is in a natural, or convenient, location for the user to view a target through the peep hole. To locate the mount on the bow string at the preferred position a clip is secured firmly on the bow string.
