DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Various embodiments will be described in detail with reference to the drawings, wherein like reference numerals represent like parts and assemblies throughout the several views. Reference to various embodiments does not limit the scope of the claims attached hereto. Additionally, any examples set forth in this specification are not intended to be limiting and merely set forth some of the many possible embodiments for the appended claims.
FIG. 1 illustrates an example light emitting head accessory 100 attached to an athletic cap 102 according to the present disclosure. In example embodiments, light emitting head accessory 100 can be removed from athletic cap 102. In other embodiments, light emitting head accessory 100 is permanently attached to athletic cap 102.
As described in more detail below, light emitting head accessory 100 includes an array of light emission devices. The array is controlled by a processor to selectively illuminate some of the light emission devices in a desired pattern or arrangement. For example, a message can be displayed on the array, such as “GO TEAM!!!,” as shown in FIG. 1. The light emitting head accessory 100 is typically arranged around a forehead of a person (either directly or on another article, such as a hat). If worn by a spectator at a sporting event, for example, the arrangement does not substantially obstruct the view of other spectators.
FIG. 2-3 show the structure of the example light emitting head accessory 100 in further detail. FIG. 2 is a schematic diagram of the front surface of example light emitting head accessory 100. FIG. 3 is a schematic diagram of the back surface of example light emitting head accessory 100.
Looking to FIG. 2, the light emitting head accessory 100 includes a strip of flexible material 202. In some embodiments, the strip of flexible material 202 runs the entire length of the light emitting head accessory 100 and is sized to fit around a persons head. In some embodiments, the light emitting head accessory 100 has a length in a range from about 10 inches to about 50 inches, and preferably in a range from about 20 inches to about 30 inches. In some embodiments, the light emitting head accessory 100 has a height in a range from about a half an inch to about 6 inches, and preferably from about 1 inch to about 4 inches. In other embodiments, the length and height is greater or smaller than these ranges. In some embodiments flexible material 202 includes multiple layers of materials or multiple types of materials. Examples of flexible materials include fabric, elastic, rubber, cardboard, paper, plastic, a flexible circuit board, or other flexible materials or combinations thereof. The flexible material allows the light emitting head accessory 100 to confirm to the size and shape of a person's head or a hat in some embodiments. In yet other embodiments, a strip of material is used that is substantially rigid, such as made out of a substantially rigid plastic.
The strip of flexible material 202 has a forward facing surface on which an array of light emission devices 204 are positioned. In some embodiments the array of light emission devices is arranged directly on the strip of flexible material. In other embodiments, the array of light emission devices is arranged on another material that is supported by the strip of flexible material 202. The array of light emission devices 204 contains an array (or matrix) of individual light emission devices 206. In example embodiments, the array of light emission devices 204 is a plurality of light emitting diodes (“LEDs”). In such an example, the individual light emission devices 206 are individual LEDs. In other embodiments, the array of light emission devices 204 is a liquid crystal display (“LCD”) panel, a plurality of light bulbs (such as incandescent, halogen, florescent, etc.), an organic light emitting diode (“OLED”) panel, an electroluminescent display (“ELD”), or an electronic paper (“e-paper”) display. Other embodiments include other light emission devices. A light emission device includes devices that selectively reflect light, but do not actually generate light. In some of these examples, the individual light emission devices 206 are individual pixels on the display.
Because the array of light emission devices are connected to a strip of flexible material 202, the array of light emission devices is also flexible in some embodiments. In some embodiments the array of light emission devices forms a loop (e.g., circular or elliptical when viewed from the top) so as to surround or substantially surround the head. In some embodiments a length of the array is in a range from about 50% to about 100% of the length of the strip of flexible material 102, and preferably in a range from about 75% to about 95% of the length of the strip of flexible material 102. In this way, a pattern or arrangement of illuminated light emission devices can be presented around most, or all, of the light emitting head accessory 100. For example, the pattern or arrangement can be displayed on the front and sides of the light emitting head accessory 100, and on or near the back of the light emitting head accessory 100 in some embodiments.
In example embodiments, such as the one shown in FIG. 2, the array of light emission devices 204 includes a plurality of rows and columns of individual light emission devices 204. In one example, the array of light emission devices 204 has a quantity of columns in a range from about 20 to about 50. In other embodiments, the quantity of columns is in the range from about 50 to about 2000 (or more, such as 3000, 4000, 10000, etc). Other embodiments include greater or fewer columns. The quantity of columns is dictated in part by the length of the array of light emission devices 204 used on the light emitting head accessory 100 and the size of the individual light emission devices.
In one example, the array of light emission devices 204 has a quantity of rows in a range from about 5 to about 11. In other embodiments, the quantity of rows is in the range from about 12 to about 500. Other embodiments include greater or fewer rows. The quantity of rows is dictated in part by the height of the array of light emission devices 204 used on the light emitting head accessory 100 and the size of the individual light emission devices. The quantity of columns and rows is also dictated by the display technology used for the array of light emission devices 204. In some embodiments utilizing higher resolution panels, such as LCD or OLED, there are hundreds of rows and columns of individual light emission devices 206. There is no inherent limit in how many rows and columns could be used. Considerations are increased cost and size of the array of light emission devices 204 as more rows and columns are added. In addition, the level of resolution desired is a consideration. If a high level of resolution is desired, there should be a greater amount of rows and columns of individual light emission devices 206 and the rows and columns should be spaced closer together.
Depending on the type of display used, the array of light emission devices 204 is capable of one color display, multi color display, or full color display. For example, in examples where the light emitting head accessory 100 includes an LCD, OLED, or multi-color LED video panel as the array of light emission devices 204, full color text, images, and video may be displayed. In other embodiments, implementing less expensive single color LED arrays as the array of light emission devices 204, only single colors of text, images, and video are displayed. In addition, less complex and less expensive versions of the light emitting head accessory 100 operate to display static and/or scrolling text or simple animations.
The light emitting head accessory 100 also includes an electronics enclosure 208 in some embodiments. In example embodiments, the electronics enclosure 208 contains a logic circuit, and a power source. A data communication device is also included in some embodiments. These devices will be discussed in further detail with regard to FIG. 4. In example embodiments, the electronics enclosure 208 includes an input device 210, for user interaction and control of the light emitting head accessory 100. In example embodiments, the light emitting head accessory 100 includes at least one input device 210 connected to the logic circuit. The input device 210 controls the arrangements displayed on the array of light emission devices 204. In example embodiments, the input device 210 is a button that can be pressed to cycle through displaying a series of different arrangements on the array of light emission devices 204. In other embodiments, the input device 210 is a switch, dial, keypad, or other appropriate input device. Some embodiments of input device 210 include a wireless receiver (or transceiver), for receiving a data signal via a infrared, radio frequency, or other communication device. In some embodiments, there is more than one input device 210. In example embodiments, the input device is used to turn the power on and off to the light emitting head accessory 100. In other embodiments, the input may be configured to only turn the power on or off to the light emitting head accessory 100.
In some embodiments, the light emitting head accessory 100 also includes a plurality of strands 212 attached to the strip of flexible material 202. The strands 212 are positioned to hang downward below the strip of flexible material 202. The strands 212 incorporate a second array of light emission devices 214. Similar to the array of light emission devices 204, the second array of light emission devices 214 contains an array (or matrix) of individual light emission devices 216. In example embodiments, there are between about 10-30 strands 212 going around the entire circumference of the light emitting head accessory 100. In other embodiments there are greater or fewer strands. In example embodiments, each strand has between about 1-20 individual light emission devices 216. In other embodiments there are greater or fewer amounts of individual light emission devices 216 on each strand or none at all.

In the example embodiment shown in FIG. 10, the example light emitting head accessory 100 includes the data connection device 404 connected to the logic circuit 400. In example embodiments, the data connection device 404 is a wireless communication device, such as a BLUETOOTH® adapter, a cellular network adapter, or other radio frequency enabled communication device. In other embodiments, the data connection device 404 is a wired communication device, such as a Universal Serial Bus (“USB”) port. It is contemplated that other wireless or wired communication devices could be used for the data connection device 404.
In the embodiments employing a BLUETOOTH® adapter, an external device such as the mobile telephone 1202 is paired with the BLUETOOTH® adapter implementation of the data connection device 404 of the light emitting head accessory 100. In other embodiments employing a BLUETOOTH® adapter, a smart phone, personal digital assistant, netbook, or laptop with a BLUETOOTH® adapter could also be used in lieu of the mobile telephone 1202. In example embodiments, the person 1200 can determine what will be shown on the light emitting head accessory 100 by sending instructions from connected mobile telephone 1202. For example, the person 1200 could type the alphanumeric message 1204 “GO TEAM!” into his mobile telephone 1202 and send the instruction via the BLUETOOTH® connection to the light emitting head accessory 100. The light emitting head accessory 100 receives the instruction at the data connection device 404 implemented as a BLUETOOTH® adapter. The data connection device 404 relays the instruction to the logic circuit 400, which carries out the instruction by illuminating the appropriate individual light emission devices 206 in the array of light emission devices 204 to display “GO TEAM!” This same method can also be used by a person 1200 to send instructions to display other text, images, animations, videos, etc. It is even contemplated that the person 1200 would be able to take a picture on his mobile telephone 1202 and instantly send the picture via the BLUETOOTH® connection to the light emitting head accessory 100 to be displayed in real time. In other embodiments, a USB or other cable would be used to connect the mobile telephone 1202 to the light emitting head accessory 100. Once connected, the method of sending instructions and content to the light emitting head accessory 100 from the mobile telephone 1202 proceeds the same as outline above.
In some embodiments employing a cellular network adapter, the device receives instructions from the mobile telephone 1202 via a text message, such as a short message service (“SMS”) message. Specifically, a spectator could compose a text message and send it to a number specific to the light emitting head accessory 100. The text message would contain instructions that could be implemented according to the method above. In other embodiments, the light emitting head accessory 100 is connected to a wireless network such that the light emitting head accessory 100 can be controlled remotely from another location at the game or even across a Wide Area Network (“WAN”), such as the Internet. In some embodiments an arrangement, pattern, or message is only displayed on light emitting head accessory 100 if a user has paid a subscription fee to a service provider.
In some embodiments a remote control device is used to control light emitting head accessory 100. An example of a remote control device is a cell phone configured to communicate with the light emitting head accessory. Another example of a remote control device is a key fob type device including one or more buttons. Each button is associated with a predetermined pattern or arrangement (which may include a message, graphic, text, animation, or combination thereof). When one of the buttons is selected (such as at the occurrence of an event), a signal is sent to the light emitting head accessory 100, which displays the associated pattern or arrangement. For example, upon the occurrence of a touchdown in a football game, the user selects a button associated with a touchdown arrangement. The remote control sends a signal to the light emitting head accessory 100, and the associated pattern or arrangement is displayed. In some embodiments the display continues until another button is pressed, or until the pattern or arrangement has completed, or until a predetermined time period has elapsed (e.g., a range from about 5 seconds to about 60 seconds).
Though the person 1200 was described in the previous examples as being both the person sending the instructions and wearing the light emitting head accessory 100, it is contemplated that in example embodiments other people or machines could remotely control the light emitting head accessory 100 via the wireless data connection 408. For example, a machine updates the light emitting head accessory 100 via the wireless data connection 408 in the example embodiment described above where a concessionaire is wearing the light emitting head accessory 100 and updated scores and statistics or other information are sent to the light emitting head accessory 100 in real time from a computing system automatically aggregating and sending the desired information.
In example embodiments, the communication between the mobile telephone 1202 and the light emitting head accessory 100 is bi-directional, such that the light emitting head accessory 100 sends information, such as status, back to the mobile telephone 1202.
FIG. 13 is a perspective view of the light emitting head accessory 100 worn directly on the head of the person 1200. In example embodiments, the person 1200 wears the light emitting head accessory 100 directly on his head by placing the strip of flexible material 202 against the his forehead and connecting the first fastening devices 218 to the second fastening devices 220 at the back of his head. In example embodiments, the third fastening device 222 is also connected to the fourth fastening device 224. The plurality of strands 212 attached to the strip of flexible material 202 hang downward from the light emitting head accessory 100. The strands 212 incorporate the second array of light emission devices 214. In example embodiments, the strands 212 do not block the vision of the person 1200 because they are thin enough that the person 1200 can see around them. In other embodiments, the strands do not hang down from the entire circumference of the light emitting head accessory 100, such as to hang only on the sides and back of the person's head. This allows the user's face to be free of strands so that the person 1200 has a clear and unobstructed view.
