Safety is an important concern among vehicle operators and pedestrians alike. Often cyclists and drivers share the same route and clearly communicating a cyclist's intended direction of travel to the drivers and other cyclists decreases the risk of accidents. Cyclists often communicate their intended direction of travel using conventional hand signals. Unfortunately, however, these hand signals go unnoticed, especially under circumstances of poor ambient illumination. In response to the dangers of riding, cyclists often wear protective helmets for safety. It would, therefore, be beneficial to incorporate further safety features, such as illumination, into the protective helmet for increased visibility. In addition, the illumination assembly should be adaptable to fit around any conventional article of headgear.

Aspects of the present invention are disclosed in the following description and related figures directed to specific embodiments of the invention. Those skilled in the art will recognize that alternate embodiments may be devised without departing from the spirit or the scope of the claims. Additionally, well-known elements of exemplary embodiments of the invention will not be described in detail or will be omitted so as not to obscure the relevant details of the invention. Further, to facilitate an understanding of the description discussion of several terms used herein follows.
As used herein, the word “exemplary” means “serving as an example, instance or illustration.” The embodiments described herein are not limiting, but rather are exemplary only. It should be understood that the described embodiments are not necessarily to be construed as preferred or advantageous over other embodiments. Moreover, the terms “embodiments of the invention,” “embodiments,” or “invention” do not require that all embodiments of the invention include the discussed feature, advantage, or mode of operation.
Further, many embodiments are described in terms of sequences of actions to be performed by, for example, elements of a computing device. It will be recognized that various actions described herein can be performed by specific circuits (e.g., application specific integrated circuits (ASICs)), by program instructions being executed by one or more processors, or by a combination of both. Additionally, these sequence of actions described herein can be considered to be embodied entirely within any form of computer readable storage medium having stored therein a corresponding set of computer instructions that upon execution would cause an associated processor to perform the functionality described herein. Thus, the various aspects of the invention may be embodied in a number of different forms, all of which have been contemplated to be within the scope of the claimed subject matter. In addition, for each of the embodiments described herein, the corresponding form of any such embodiments may be described herein as, for example, “logic configured to” perform the described action.
The present invention relates generally to a light notification system, and in particular to an adaptive light signal assembly for headgear or the equivalent thereof. The light signal assembly may be universally affixable to an exterior surface of an article of headgear, such as a protective helmet, to enhance the visibility and safety of a wearer, especially in vehicular and pedestrian traffic. It should be appreciated that headgear may take any desired form, including but not limited to, various sporting helmets, such as bicycle, scooter, motorcycle, skateboarding, and equestrian helmets, as well as construction hard-hats, safety helmets, military helmets, baseball hats, and the like.
According to an exemplary embodiment, a light signal assembly for headgear may be described herein. The light signal assembly may provide visual confirmation of a wearer's intended movement (e.g., to continue forward, to turn or bear right, to turn or bear left, to stop, etc.) in a manner that is readily observable and understandable by passersby. The light signal assembly may include an elongated flexible light strip, the light strip being generally conformable to the curved surfaces of the headgear, and mountable thereto around the entire circumference. The light strip may be populated with a plurality of light sources that are configured to create meaningful direction signals when controllably actuated via a controller. For example, in some exemplary embodiments, the light strip may include turn signals, sidelights, a backlight, and a front headlight. The turn signals and/or sidelights may serve as directional indicators, while the backlight and/or sidelights may further serve as a brake indicator. In addition, the front headlight may increase wearer visibility, especially in low or poor ambient light environments, by projecting an illuminating beam toward the path ahead.
The plurality of light sources may be connected in series, parallel or a combination thereof on at least one conducive base acting as an electrical connector. In some exemplary embodiments, the conductive base may form a physical mounting platform; alternatively, the conductive base may be mounted on any suitable substrate (e.g., plastic) to provide an elongated light strip. The conductive base may operatively connect to a power source to activate the light sources.
An electrical control unit may be mounted within the light-emitting display strip and be configured to selectively control the plurality of light sources. The electrical control unit may be, for instance, disposed within the backlight portion of the light-emitting display strip. In one exemplary embodiment, the electrical control unit may include a microprocessor having a memory with at least one stored control program executable by the microprocessor for controlling the illumination of the plurality of light sources, and control circuity for activating/deactivating the individual light sources. It should be appreciated, however, that the electrical control unit may be equipped with any number of microprocessors, memory storage units, and electrical components suitable for controlling the plurality of light sources within the light signal assembly. For example, changes in the supply of electrical current may dim, brighten, and turn on or off the light sources as may be understood by a person having ordinary skill in the art. The electrical control unit may also regulate various lighting characteristics, such as, but not limited to, the quantity, frequency, intensity, and color of the light sources.
In some exemplary embodiments, a remote controller may wirelessly communicate (e.g., by Wi-Fi or BLUETOOTH) with the electrical control unit to transmit a desired light sequence instruction thereto. In other exemplary embodiments, these components may communicate via a wired connection, such as a USB or Ethernet cable.
The process data and light sequence instructions may be stored in memory. These processes and instructions may also be stored on a storage medium disk such as a hard drive (HDD) or portable storage medium. Further, the claimed advancements are not limited by the form of the computer-readable media on which the instructions of the inventive process are stored. For example, the instructions may be stored on RAM, ROM, PROM, EPROM, EEPROM, hard disk or any other information processing device.
