LED light and sound ball for emergency responders

Abstract

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The LED light and sound ball for emergency responders, designated generally as 10 in the drawings, is shown in FIG. 1, having been activated upon contact after being launched by an emergency responder ER from a launcher L to illuminate an area of interest P, such as a potential crime scene. While the LED light and sound ball may be thrown, for greater range the LED light and sound ball is fired from a launcher that has a cylinder loaded with a compressed gas, such as compressed air or carbon dioxide, to launch emergency response projectiles. The details of the LED light and sound ball 10 are best seen in FIGS. 2-4. The light ball includes a clear polymeric, spherical, slightly flexible outer casing 20, similar to hollow, transparent polymer toy balls. As with the toy balls, the outer casing 20 is resilient and yields upon impact, but returns to its spherical shape thereafter. The outer casing 20 may be in two hemispherical pieces that are fused together to house the remaining components therein. A rectangular, clear inner casing 40 (FIG. 4) is mounted within the outer casing 20, and a printed circuit board 22 is mounted within the inner casing 40. The circuit board 22 includes a plurality of conductive traces 28 (shown in FIGS. 2 and 3) for making the electrical connections, as described below with respect to the block diagram of FIG. 5. It should be noted that the traces 28 shown in FIGS. 2-3 are for illustrative purposes only and are not intended to represent the actual traces on the circuit board 22. A plurality of rig rods 21 extend through the inner casing 40 and include curved heads 23 that are in close proximity to the inner surface 25 of the spherical outer casing 20. Upon impact with a surface, the outer casing 20 flexes and pushes against one of the curved heads 23 (depending on the area of impact on the spherical outer casing 20) and pushes its associated rig rod 21 inward, thereby closing an electrical contact (not shown). The light ball 10 also includes a plurality of high-power LEDs 24 mounted on or near the circuit board 22, capable of producing 2700 lumens or more in total, one or more batteries 30 for powering the light ball, a sound generator 27 and an integrated circuit or latch 26. The rig rods 21 are, in essence, momentary switches connected in parallel and having elongated contact pins that are activated by contact of the ball 10 with an object applying sufficient pressure to the head of at least one contact pin to momentarily apply power to the LEDs 24. The rig rods are spaced radially so that contact at any angle is sufficient. Once turned on, the latch 26 keeps the LEDs 24 and sound generator 27 turned on until power is dissipated or disconnected.

(9) FIG. 5 shows a block diagram 50 of the electrical circuit of the LED light ball for emergency responders 10. The positive electrode of the battery 30 is connected to one of the contacts of each of the rig rods 21 and to a first terminal of the circuit or latch 26 by first wire and/or trace 52. The other contact of each of the rig rods 21 is connected to a second terminal of the circuit or latch 26 by a second wire and/or trace 54. A third terminal of the integrated circuit or latch 26 is connected to the positive lead of all of the LEDs 24 and the positive lead of the sound generator 27 by a third wire and/or trace 56. The negative electrode of the battery 30 is connected to a fourth terminal of the circuit or latch 26 and to the negative lead of all of the LEDs 24 and the negative lead of the sound generator 27 by a fourth wire and/or trace 58. The contacts for the rig rods 21 are wired in parallel, such that a single activated rig rod triggers the integrated circuit or latch 26 to connect the positive terminal of the internal battery (or batteries) to all of the LEDs 24 and the sound generator 27. The LEDs, for example, can provide 900 lumens per light or more equaling 2700 lumens or more in total with three LEDs. The circuit 26 may be a simple latching micro-relay that maintains the LEDs lit and the sound generator 27 turned on, once triggered by one or more of the rig rods 21. In other embodiments, the circuit 26 is a programmable integrated circuit that can provide strobe-like, light pattern flashing or other lighting and sound functions. Furthermore, the rig rods 21 are only one way of triggering the circuit 26, and other devices or circuits for triggering the circuit 26, such as an accelerometer, are contemplated.

(10) A further embodiment of the LED light and sound ball (or projectile) 60 is shown in FIG. 6. The LED light and sound projectile 60 has an outer casing in the form of a two-piece elongated cylinder with rounded ends. The LED light and sound projectile 60 includes all the components as described with respect to the first embodiment of FIGS. 1-5. The first, front piece 64 is in the form of a short cylinder with a rounded closed end 68 and an open second end. The second, rear piece is in the form of an elongate cylinder 62 with a rounded closed end 66 opposite to the rounded closed end 68 of the first, front piece 64 and an open second end. The first front piece 64 has a larger diameter than the second rear piece 62 and slides over the second piece 62, the open second end of the second piece 62 being frictionally inserted into the open end of the first front piece 64. The previously described rig rods 21 are disposed within the projectile 60 such that their heads 23 are in close proximity to an inner surface of the rounded closed end 68. Upon impact with a surface, the front piece 64 is driven backwards against the rig rods 21, thereby activating the LEDs 24 and sound generator 27, as described above with respect to the embodiment of FIGS. 1-5. Unlike the LED light and sound ball 10, the LED light and sound projectile 60 is less likely to continue rolling past the area of interest.
