Abstract: A signaling device is disclosed comprising an electronic circuit positioned within a housing and comprising at least one LED, a light diffuser manufactured from a non-opaque material and a USB Port. Side edges of the housing each comprise a barb engaging slot therein. A cap end covering the USB port and comprising a pair of flexible fingers each comprising a barb-like feature for engaging respective ones of the barb engaging slots comprises an actuating part fabricated from a compressible rubberlike material which is secured towards a second end of each of the flexible fingers. Compressing the actuating part motivates the outer ends of the flexible fingers to move apart, thereby releasing the barb-like features from their respective barb engaging slot and allowing the cap to be removed from the housing.

Abstract: A light-emitting beacon for attachment to a helmet comprising a convex outer surface is disclosed. The beacon comprises a printed circuit board assembly arranged within a hollow space between a carapace and a battery such that a first surface of a circuit board assembly faces the power source and a second surface of the circuit board assembly faces the carapace. The circuit board assembly further comprises a plurality of LEDs arranged on the second surface wherein a first of the LEDs emits a first light visible from a first lateral side of the carapace and a second of the LEDs emits a second light visible from a second lateral side of the carapace. There is also discloses a light activated beacon comprising at least one LED activated or deactivated in response to light sensed by at least one of a plurality of photosensors arranged on the second outer surface.

Abstract: A light-emitting beacon a dome e translucent or transparent carapace and a base. A printed circuit board assembly is arranged within the hollow space adjacent the carapace and above and on either side of a battery, the circuit board assembly comprising a plurality of LEDs arranged to emit light out of the carapace and such that when emitting at least one of the LEDs is visible from either side of the carapace. In a particular embodiment the light-emitting beacon is for mounting on a helmet and comprises an elongate carapace a first translucent or transparent material joined to a base having a concave undersurface and manufactured from a second plastic material, the first material of a greater hardness than the second material. The carapace is dome like and at least one LED arranged to emit light out of the carapace.

Abstract: An electronic device comprising a lens and a selector ring is disclosed. The selector ring is mounted for rotation about the lens and comprises a plurality of tabs projecting inwards towards the lens which engaging with and are held within a tab receiving groove comprising a plurality of spaced notches. Each of the notches is dimensioned to receive one of said tabs. A wave spring positioned between an annular ledge of the lens and the selector ring which biases the plurality of tabs against the groove and such that when each of the plurality of tabs is positioned adjacent a respective one of the notches, the tabs are biased into the notches thereby preventing said selector ring from being rotated. A user disengages the tabs from the notches by pressing said selector ring against the bias of the wave spring, thereby allowing the selector ring to be rotated.
