(20) FIG. 1 is a schematic representation of a protective helmet system 10 according to one exemplary embodiment of the present invention. The helmet system 10 comprises a helmet 20, a remote control 180, and a designated mobile computing device (e.g. a smartphone running a mobile app) having at least a processor. The helmet 20 comprises an upper shell 31, a bottom shell 32, a harness 33, a LED strip 60, optical sensors (e.g. cameras, ambient light level sensors) for capturing images of surrounding objects, environmental and road conditions and an electronics box 70, all of which are integrated with a liner 40 to form the helmet 20 as described in further detail as follows. The upper shell 31 and the bottom shell 32 are made of hard materials and are means for protecting a rider who wears the helmet 20. The harness 33 enables the helmet 20 to be fastened to the rider's head. The LED strip 60 is installed on the helmet 20, and has plural LEDs for producing light signals such that the rider becomes more visible to surrounding vehicles and pedestrians, thereby promoting safety to the rider.

(25) In addition, the electronics box 70 may further configured to house a battery 74. In one mode of operation, the control module can transmit the information about the battery 74 to the designated mobile computing device so that the remaining energy on the battery 74 can be displayed.

(26) FIGS. 4A, 4B and 4C depict different views of the LED strip 60 in accordance with one embodiment of the present invention. The LED strip 60 comprises a flexible base 68, and a plurality of LEDs installed on the flexible base 68. Preferably, the plurality of LEDs includes a front-right LED 62, a back-right LED 63, a back LED 64, a back-left LED 65, a front-left LED 66, a left brim LED 671, a right brim LED 672 and a center brim LED 673. In one preferred embodiment, each of the front-right LED 62 and the front-left LED 66 is preferably a super-bright dual-color orange and white LED; the back-right LED 63 and the back-left LED 65 are preferably super bright orange LEDs; the back LED 64 is preferably a super bright RED LED; the left brim LED 671 and the right brim LED 672 are preferably orange LEDs; the center brim LED 673 is red.

(27) The electronic box further comprises one or more of proximity sensors 77 for sensing surrounding objects, including vehicles, pedestrians, and other stationary obstacles; one or more speakers 78, one or more vibration motors 79 and one or more motion sensors 710 (e.g. inertial sensors) for sensing deceleration of the rider or detecting sharp movement of the rider caused by an accident such as a crash.

(28) In the normal time when the rider is biking straight, the control module may be configured to signal the LED strip 60 so that the back LED 64 is blinking. In this way, the rider will become more visible to surrounding vehicles and pedestrians. The rider can also designate blinking patterns for the LED strip 60 under different situations.

(29) When detecting an approaching vehicle via the one or more proximity sensors 77, the control module is configured, to control the center brim LED 673 to blink and increase the brightness of the LED strip 60, and to trigger the one or more vibration motors 79 to vibrate and the one or more speakers 78 to emit alarming sound thus to notify the rider. When the control module detects occurrence of high impact on the helmet through the one or more motion sensors 710, the control module can also transmit signal to the designated mobile computing device to trigger emergency call or messaging function on the designated mobile computing device.

(30) FIGS. 5A-5D depict perspective views regarding different versions of the remote control 180 according to one embodiment of the present invention. Refer to the two versions shown in FIGS. 5A and 5B first. The remote control 180 comprises a left button 51, a right button 52, an electronics box 50, and a mount 53 that is attached to a handle bar of the bicycle (or a handle bar of any vehicle that the rider rides on). The left button 51 and right button 52 are preferably made of soft rubber plastic. It is also preferable that the casing is plastic. Preferably, the mount 53 is plastic. In each of the versions shown in FIGS. 5A and 5B, the left button 51 and the right button 52 are positioned on or over the mount 53. In FIGS. 5C and 5D, there are two other versions each of which has a mount 54 having two wired buttons as a left button and a right button.

(31) FIGS. 6 and 7 are two flowcharts showing examples of firmware programs implemented in the control module and in the remote control 180, respectively.

(32) Note that it is required to install electronics into the helmet to provide functions thereto. In this regard, one or more electronic boxes, including the electronics box 70, are included in the helmet 20. Advantageously, each electronic box may be designed with a further objective of providing protection to the rider against being impacted by electronic components in the electronic box in case of an accident.

(33) FIGS. 8A, 8B and 8C depict a perspective exploded view, a bottom cross-section view and a side cross-section view, respectively, of a helmet with an electronics box having a wing design in accordance with one embodiment of the present invention. In particular, FIGS. 8A, 8B and 8C illustrate a method of integrating electronics into a helmet 82 with an electronics box 200 that features the wing design. In these figures, a cover 80 of the electronics box 200, a bottom 81 of the electronics box 200, the helmet 82 that the electronics are integrated in, and an exemplary PCB 83 that represents the electronics are shown. How this design enables the integration of electronics into the helmet 82 is through the following two ways.

(34) First, a wing 91 protrudes from the cover 80 that extends the contact of the electronics box 200 to the surrounding helmet section of the helmet 82. During impact, the surrounding area absorbs the impact energy.

(35) Second, a cavity 92 is situated between the bottom 81 of the electronics box 200 and the helmet 82. This cavity 92 prevents the compression of the foam of the helmet 82 beneath the electronics box 200 at the early stage of impact. During impact, the wing 91 transfers the impact energy to the area beneath the wing 91 first as the foam at this area collapse, this cavity 92 shrinks to a point that the foam beneath the bottom 81 of the electronics box 200 also starts to collapse and thus absorbs energy. If this cavity 92 were not there, the impact energy would pass to the foam beneath the bottom 81 of the electronics box 200 at the very first beginning of impact. Thus, more energy will be passed to this area where the foam is thinner because of the existence of the electronics box 200. This cavity 92 thus acts as a buffer to let the foam that surrounds the electronics box 200, which is thicker, absorb the energy first, thus decreasing the energy that the foam beneath the electronics box 200 need to absorb, and passing less energy to the head of the rider.

(36) FIGS. 9A and 9B depict a perspective view and a rear view, respectively, of a helmet with a LED display 300 in accordance with one embodiment of the present invention. The LED display 300 comprises a flexible base and a two-dimensional (2D) array of LEDs installed on the flexible base. As seen in FIG. 9A, the LED display 300 is curved to match the curved contour of the helmet. In particular, the LED display 300 is configured to produce visual information to vehicles and pedestrians surrounding the rider, causing the rider to be able to communicate with the surrounding vehicles and pedestrians using contextual display contents including graphical, textual and/or animated signs to thereby promote safety to the rider. In some embodiments, the processor of the designated mobile computing device is configured to provide the contextual display contents to the LED display. The graphical, textual and/or animated signs to be displayed in the LED display 300 may be configured and input using the designate mobile computing device through the communication module, and stored in the control module. For example, if a motorist is driving too closely to the rider as detected by the proximity sensor, the LED display may display a Danger warning sign to warn the motorist to keep a further distance. On the other hand, when the rider perceives safe road manner of a motorist, the rider may command the LED display to display a message of compliment.

(37) In one mode of operation, the control module may be configured to control the LED display to display a logo to identify the rider from other members of a riding group; and the communication module is configured to establish a point-to-multipoint communication group such that the rider can transmit or receive real-time and/or just-in-time information to other members of the riding group. For example, a member leading the group may command the LED display to display navigational directions (e.g. turn left/right ahead) and oncoming road condition (e.g. Steep Downward Slop Ahead). The communication modules of the one or more members' helmets can be configured in master-slave mode in which the contents displayed in the master helmet's LED display is propagated to one or more slave helmets' LED displays. In other words, the point-to-multipoint communication group is configured in master-slave mode in which the contextual display contents displayed in a master helmet's LED display is propagated to one or more slave helmets' LED displays. In another example, a group member may send a distress signal to the group when there is an accident. The control module is configured to control the LED display to display the distress signal. The communication modules of the one or more members' helmets can be configured such that the distress signal, identifying which member needs help and what kind of help, gets propagated to the one or more slave helmets' LED displays

(38) Preferably, the LED display 300 may include a configuration of 7 by 11 array optimized to strike a balance between the visible distance range of the helmet and power consumption of the LED display while providing a sufficiently rich contextual display content. As the number of LEDs increases beyond that of the 7 by 11 array, the power consumption becomes excessive or each LED becomes dimmer without a proportionally increased available electrical current. The particular configuration of 7 by 11 array also allows the optimized display of text (e.g. simultaneous display of two letters scrolling smoothly).
