The LED light and sound ball for emergency responders is activated upon contact after being fired from a launcher to illuminate and direct responders to an area of interest, such as a potential crime scene. The ball includes a clear polymeric, spherical outer casing, and a rectangular, clear inner casing having a circuit board mounted therein. A plurality of rig rods extend through the inner casing and include curved heads that are in close proximity to the inner surface of the spherical outer casing. Upon impact, the outer casing flexes and pushes against one of the curved heads and pushes its associated rig rod inward, thereby closing a contact that triggers a control circuit to continuously illuminate a plurality of bright LEDs and continuously activate a sound generator that emits a foghorn-type alarm. The LED light and sound ball may be thrown or fired from a conventional compressed air launcher.

An open field game arrangement includes glowing targets and provides responses, such as lights and sounds, when the targets are hit.

Implementations of an announcer ball comprise a structure configured to be tossed or otherwise deployed and to provide a lighted visual indicator, such as a blue light indicator, to indicate the entry and presence of police or other personnel in a location. In some implementations, a method of using the announcer ball comprises tossing or otherwise deploying the announcer ball into a dwelling or other suitable location and the announcer ball emitting a lighted visual indicator, such as a blue light indicator, in the location to indicate the entry and presence of police or other personnel.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

An electronic tracking system for assisting a user in determining distances to landmarks and objects in a sporting environment includes a user tracking system for determining the location of a user, a heads up display for displaying information to the user, and a processor operable to communicate with the user tracking system and the heads up display. The heads up display is designed to be worn on the user's head, and to display an image within the user's field of view. The processor is programmed to determine a distance between the user's determined location and an object or a landmark on. This information is displayed via the heads up display as a numeric representation of the determined distance.
