DETAILED DESCRIPTION

[0034] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be used, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure. [0035] A concept and design of an electronic add-on to the bike structure is described herein. The add-on is composed of a smart pedal in conjunction with a computer-based application, i.e. the recommender system or coach. The system is capable of recommending appropriate cycling strategies to improve the biking experience, based on the measured cycling characteristics in the outdoor or indoor environment. The virtual coaching system can grow and adapt with a rider the more the rider uses the system by combining and analyzing data from multiple sessions. The add-on can be augmented by other physiological transducers to provide exercise outcomes as the analogous to stationary bike in the gym.

[0036] FIG. 1 depicts an illustration of an embodiment of a virtual coach system 100. The virtual coach system 100 includes a pedal sensor 110 and a virtual coach 120. In some embodiments, the pedal sensor 1 10 is communicatively coupled to the virtual coach 120. The pedal sensor 110 and the virtual coach 120 may be connected via wired or wireless links. The wired links may include coaxial cable lines or optical fiber lines. The wireless links may include BLUETOOTH or Wi-Fi. In some embodiments, the wireless links may include any cellular network standards sued to communicate among mobile devices, including standards that qualify as 1G, 2G, 3G, or 4G.

[0037] In an embodiment, the pedal sensor 110 can communicate with the virtual coach 120 to transmit characteristics of a bike via a wireless connection. The virtual coach 120 can display the received information and characteristics of the bike. In some embodiments, the virtual coach 120 can be an application executing on a hand-held computing device. In one embodiment, the virtual coach 120 can execute on a smart phone based application such as an IPHONE device manufactured by Apple Inc. In other embodiments, the virtual coach 120 can execute on a wearable computing device such as Google Glass device manufactured by Google, Inc. In some embodiments, the virtual coach 120 can be coupled to a bike frame. In one embodiment, the virtual coach 120 can be coupled to the handlebars of a bike so a rider can view the display during a cycling session. In an embodiment, the virtual coach 120 can transmit the characteristics of the bike to a separate computing device to review and analyze the information after the cycling session is over.

[0038] In some embodiments, the pedal sensor 1 10 is coupled to a pedal of a bike 130 being operated by a rider 140. As the rider 140 applies force to the pedal, the pedal has a rotation movement that can be measured to determine certain characteristics of the bike 130, for example, bike speed. In some embodiments, the pedal sensor 110 includes various instruments to measure the characteristics of the bike 130 during a cycling session. The pedal sensor 1 10 can then transmit these characteristics to the virtual coach 120. As illustrated in FIG. 1, the characteristics can be displayed to the rider 140. Further, the virtual coach can manipulate the characteristics to generate recommendations to the rider to increase the riding experience.

[0039] As stated above, the pedal sensor is detecting characteristics of the bike 130 based on the operation of the pedal. FIG. 2 depicts an illustration of an embodiment of an expanded view of a pedal mechanism 200. In some embodiments, the pedal mechanism includes a pedal 210, a crank shaft 220, and a chainring 230. In an embodiment, the pedal mechanism 200 may be coupled to a rear wheel 260 of a bicycle via a chain 240 and a cassette 250. As the rider applies force on the pedal, the pedal will have a movement of translation around the crank's pivot 225 and rotation around its own pivot 215. Its own pivot 215 may be any type of mechanical adapter to connect the peal to the crank shaft. The crank shaft's pivot 225 may be a connection point connecting the crank shaft to the chainring.

[0040] In some embodiments, the pedal 210 is the part of a bicycle that the rider applies force to with their foot to propel the bicycle. The pedal 210 may include a pedal shaft adapter that connects to an end of the crank shaft 220. Additionally, the pedal 210 may have a body, on which the foot rests or is attached, that is free to rotate on bearings with respect to the pedal shaft. In an embodiment, the pedal shaft may be referred to as a spindle. In some embodiments, the pedal body may include a flat surface to rest the foot on. In other embodiments, the pedal body may include a cleat connection. The cleated connection, for example, may mate with a similar cleat connection point on the rider's shoes, allowing the rider to "clip into" the bike. In an embodiment, the pedal 210 provides a connection between the cyclist's foot or shoe and the crank shaft 220, allowing the leg to propel the bicycle's wheels.

[0041] In some embodiments, the crank shaft 220 is the component of a bicycle drivetrain that converts the reciprocating motion of a rider's legs into rotational motion used to drive the chainring 230 and the chain 240, which in turn drives the rear wheel 260. In some embodiments, the crank shaft 220 transfers the force applied to the pedal 210 by the rider to the chainring 230 and the chain 240. The crank shaft 220 is coupled to the pedal 210 via the pedal shaft adapter. In some embodiments, the crank shaft 220 is coupled to the chainring 230 via a bolted connection. As the rider applies force to the pedal 210, the crank shaft 220 rotates around its connection to the chainring 230. In an embodiment, the pivot 225 for the crank shaft can be where it connects to the chainrung 230. In some embodiments, this rotational movement of the crank shaft 220 causes the chainring 230 to rotate.

[0042] In some embodiments, the chainring 230 is coupled to the crank shaft 220 and the chain 240. An end of the crank shaft 210 may be connected to a middle portion of the chainring 230. In some embodiments, the crank shaft 210 may be bolted to the chainring 230. The chainring 230 may include a threaded hole through the middle of the chainring 230 to insert a bolt and connect the crank shaft 220. As the crank shaft rotates in response to force applied by the rider, the chainring 230 may rotate causing the chain 240 move. In some embodiments, the chainring 230 may have a threaded outer surface, for example, the outer circumference of the chainring 230 may shaped as teeth. The teeth of the chainring 230 may be spaced at a particular distance to engage every link of the chain 240 as it passes over. In an embodiment, as the chainring 230 rotates, the teeth grip and pull the chain 240, causing the chain 240 to rotate.

[0043] In some embodiments, the chain 240 may include links that fit into the teeth of the chainring 230. The chain 240 may be coupled to the chainring 230 and the cassette 250 on the rear wheel 260. In some embodiments, as the chain 240 is pulled by the rotational movement of the chainring 230, the chain 240 causes the cassette 250 to rotate. In some embodiments, the cassette 250 may have a threaded outer surface referred to as teeth, similar to the chainring 230. The links of the chain 240 may be coupled to the teeth of the chainring 250. The teeth of the cassette 250 may be spaced at a particular distance to engage every link of the chain 240 as it passes over. In some embodiments, the rotational movement of the cassette 250, caused by the chain 240, may cause the rear wheel 260 to rotate.

[0044] In some embodiments, the cassette 250 may be coupled to the rear wheel 260 via a mechanical adapter. In an embodiment, the cassette 250 may include a cogset. A cogset may be coupled to a rear derailleur as part of a drivetrain to provide multiple gear ratios to the rider. In some embodiments, as the cassette 250 rotates the rear wheel 260 rotates, causing the bicycle to move. In some embodiments, the cassette 250 may transfer force from the chainring 230 and chain 240 to the rear wheel 260.

[0045] In some embodiments, the rear wheel 260 can be propelled by the force a rider applies to the pedal 210. In an embodiment, the rear wheel can be coupled to the cassette 250. The rear wheel may rotate in response to forces applied on the cassette 250. Thus, measurements taken at the pedal 210 can be used to determine a speed of the rear wheel and the speed of the bike. In some embodiments, these measurements can be transmitted to a virtual coaching system to monitor and provide recommendations to a rider during a cycling session. The measurements can be taken at both pedals of a bike (i.e., left pedal and right pedal). Further, the figures and descriptions herein may make reference to only one pedal, however the various embodiments of pedal sensors described herein can be applied to both pedals on the bike.

[0046] Interactive Cyclist Monitoring and Recommendations System

[0047] FIGS. 3A and 3B illustrate various views of a pedal sensor. FIG. 3A illustrates a side view of an embodiment of a pedal sensor 300. The pedal sensor 300 is coupled to a pedal body 340 via a pedal shaft adapter 320. The pedal sensor 300 includes a rotary sensor 310 and an electronic housing 330.

[0048] In some embodiments, the rotary sensor 310 may be connected to an end of a pedal body 340 via the pedal shaft adapter 320. In one embodiment, the rotary sensor 310 is coupled to the end of the pedal body 340, opposite of where the crank shaft is coupled to the pedal body 340 (i.e., the outer side with respect to the bike body). In some embodiments, the rotary sensor 310 may include at least one of an encoder, a continuous potentiometer, a digital counter, an accelerometer, and a gyroscope. In one embodiment, the rotary sensor 310 may include two encoders. In an embodiment, the rotary sensor 310 can measure pedaling speed as will be discussed in greater detail below. In some embodiments, the rotary sensor 310 may perform measurements continuously. In other embodiments, the rotary sensor may perform measurements once per rotation. The rotation may refer to a rotation of the pedal, crank shaft, or a wheel. In still other embodiments, the rotary sensor 310 may perform measurements at a specific time interval within a full rotation. [0049] In some embodiments, to measure the pedaling speed, the rotary sensor may measure a pedal shaft displacement. The pedal shaft displacement may include two components, a crank shaft rotation with respect to its external reference and a pedal rotation with respect to the crank shaft, as will be discussed in greater detail below.

[0050] In some embodiments, the pedal shaft adapter 320 may couple the rotary sensor 310 to the pedal body 340. The pedal shaft adapter 320 may be any type of mechanical adapter. In one embodiment, the pedal shaft adapter 340 includes a nut and bolt to affix the rotary sensor 310 to a threaded end of the shaft of the pedal body 340.

[0051] In some embodiments, the electronic housing 330 may include the rotary sensor 310. In an embodiment, the electronic housing 330 may include micromechanical types of sensors. For example, the electronic housing 330 may include at least one of a tilt sensor, an accelerometer, a gyroscope, and an inertial measurement unit (IMU). As illustrated in FIG. 3 A, the electronic housing 330 may be coupled to the pedal body 340 via a mechanical adapter. In other embodiments, the electronic housing 330 may be coupled to a crank shaft of a bike. In still other embodiments, the electronic housing 330 may be coupled to the body of the bike. In some embodiments, the electronic housing 330 and the rotary sensor 310 can be fabricated together to form one sensor. As illustrated in FIGS. 3A-3B, the electronic housing may be affixed to a bottom portion of the pedal body 340.

[0052] In some embodiments, the pedal sensor 300 may be battery powered. In an embodiment, the electronic housing 330 may include connections for a battery component. In some embodiments, the electronic housing 330 may include an electronic circuit board to power the pedal sensor 300. In an embodiment, the electronic housing 300 may include a computing device configured to collect, store, and transmit measurements from a sensor to another computing device, for example, the virtual coach. [0053] In some embodiments, the pedal body 340 may be a standard, generic bike pedal. The pedal body 340 may include a least one flat surface for a rider to press a foot down upon. In other embodiments, the pedal body 340 may be a cleat type pedal. In such an embodiment, the rider will "clip" into the cleated connection on the pedal with a cleated connection on the rider's shoe. In still other embodiments, the pedal body 340 can be any type of bike pedal available. The rotary sensor 310 may be fabricated and/or configured to connect to any shape or type of bike pedal.

[0054] The components of the pedal sensor 300, as described herein, may comply with common electronic equipment standards. In some embodiments, the pedal sensor 300 can be fabricated to fit onto any size pedal or pedal configuration. For example, in some

embodiments, the pedal sensor 300 may be fabricated to be coupled to a standard bike pedal. In other embodiments, the pedal sensor 300 may be fabricated to be coupled to a cleat type pedal. In some embodiments, all of the components of the pedal sensor 300 may be waterproof.

[0055] FIG. 3B illustrates a perspective view of the pedal sensor 300 of FIG. 3A. In more detail, FIG. 3B illustrates a cut away view of a pedal body 340 to illustrate example connection points for the pedal sensor 300 and a crank shaft. The pedal sensor 300 includes a rotary sensor 310 and an electronic housing 330. The pedal body 340 includes the a pedal shaft 350. In some embodiments, the pedal shaft 350 runs through a center portion inside of the pedal body 340. The pedal shaft 350 may be referred to as a spindle. In some

embodiments, an end of the pedal shaft include a threaded end to connect the crank shaft onto, for example, via a nut and bolt. In an embodiment, the rotary sensor 310 may connect onto the end opposite of where the crank shaft connects. The rotary sensor 310 may be coupled to the pedal shaft 350 via a pedal shaft adapter 320. [0056] FIG. 4A depicts an illustration an embodiment of angular relationship 400 to a crank shaft to a pedal. The angular relationship 400 includes a pedal 410 and a crank shaft 420. In some embodiments, the angular relationship 400 may be referred to as a pedal shaft angular displacement. In some embodiments, while cycling, the crank shaft 420 will have a movement of rotation around its pivot while the pedal 410 will have movement of translation around the crank shaft's pivot and rotation around its pivot. By measuring the relationship between pedal 410 and the crank shaft 420, the speed of the bicycle can be determined. In some embodiments, the measurements can be performed continuously, once per rotation, or at a pre-determined time interval within a full round. In some embodiments, the pedal shaft angular displacement (Θ encoder) may be composed of two components, the crank shaft rotation (©crank) and the pedal rotation (0_pedai) with respect to the crank shaft 420. The relationship may be represented by the following equation:

[0057] @pedal ® crank ® encoder

[0058] A pedal sensor, such as those described above with respect to FIGS. 1- 3B, can measure the appropriate angles of the pedal 410 and the crank shaft 420. The pedal sensor can measure the angle of the pedal with respect to its reference. In an embodiment, this reference can be the pedal shaft. Further, the pedal sensor can measure the angle of the crank shaft with respect to an external reference. In an embodiment, the external reference may be the connection point to the chainring on a bike. By combining the angle measurements from the pedal 410 and the crank shaft 420, a total sensor angle can be determined.

[0059] FIG. 4B depicts an illustration of a relationship 450 of a flywheel to a rear wheel. In some embodiments, the crank shaft angle and pedal angle can be extracted from equation 1 to determine the angular velocity of a flywheel 460. In an embodiment, the chainring of a bike may be referred to as a flywheel 460. The angular velocity of the flywheel 460 can be calculated as follows:

^ crank

[0060] 'flywheel dt

[0061] Where (oif_lywhee{) represents the angular velocity of the flywheel 460. By determining the angular velocity of the flywheel 460, the pedal sensor or the virtual coach can use the relationship between the flywheel 460 and a rear wheel 470 of a bike to determine the bike velocity (i.e., bike speed). The relationship of the flywheel 460 to the rear wheel is illustrated in FIG. 4B. In some embodiments, based on the relationship between the flywheel 460 and rear wheel 470 of a bike, the angular velocity of the rear wheel 470 and the angular velocity of the bike can be calculated as follows:

[0062] Mflywheel * ^rflywheel ^{= ω}ννΙιββΙ * ^rwheel

[0063] Vbike = dibackwheel * ^rbackwheel ⁼ * ^rbackwheel

[0064] In some embodiments, v_bike equation above can be used to determine a bike velocity of a bike with a fixed gear ratio. In an embodiment, if the bike has a fixed gear ratio (i.e., no alternating gears), the rider may be prompted to answer a few questions by the virtual coach in addition to the characteristics measured by the pedal sensor. For example, in one embodiments, the rider can enter characteristics of the bike into the virtual coach. The characteristics of the bike may include a ratio of a radius of the flywheel 460 to a radius of the backwheel 470. The characteristics of the bike may further include a bike model type and a serial number. In some embodiments, the virtual coach can be configured to look up additional bike characteristics based on the entered model type and serial number. For example, the virtual coach may look up bike characteristics via an connection to the internet. Additionally, in some embodiments, the rider can enter physical characteristics, such as age, gender, and weight.

[0065] In some embodiments, a pedal sensor can transmit the bike speed to a virtual coach. In one embodiment, the pedal sensor can include a inertial measurement unit (IMU). The output of the pedal sensor can include at least a pedal speed, a crank shaft speed, and a bike speed. In other embodiments, the virtual coach can perform the calculations without the pedal sensor. For example, in one embodiment, a virtual coach can be an application executing on a smartphone. The smartphone can have an embedded inertial measurement unit (IMU). The virtual coach can utilize the IMU of the smartphone to calculate bike speed. For example, the IMU may include a gyroscope and an accelerometer, which can be utilized to derive a bike speed during a cycling session outdoors. In such an embodiment, the virtual coach can receive measurements from the pedal sensor to calculate a current gear ratio.

[0066] FIG. 5 depicts an illustration of the steps taken in one embodiment of a method for monitoring and providing recommendations to a rider during a cycling session. In a brief overview, the method 500 can include displaying, by a virtual coach, characteristics of a bike in a first virtual cycling session, the characteristics measured by a pedal sensor during a cycling session (505). The virtual coach can assess a performance of a rider during the cycling session(510) and generate recommendations in the first virtual cycling session based on the performance of the rider (515). The virtual coach can create a second virtual cycling session based on the rider performance and the recommendations (520).

[0067] In some embodiments, the method 500 includes displaying, by a virtual coach, characteristics of a bike in a first virtual cycling session (505). In an embodiment, the display can be an interactive map. In some embodiments, the display can be a display for a hand-held computing device. In one embodiment, the display can be a display of a smart-phone. In other embodiments, the display can be coupled to a wearable computer device.

[0068] In an embodiment, the characteristics can be measured by a pedal sensor during a cycling session.

The operator of the vehicle may notice the change in the laser lights 840, 860 behavior and be alerted to the presence of the cyclist. [00116] FIG. 12 depicts an illustration of one embodiment of a visual alert 1200. In some embodiments, the safety sensor can include components for the visual alert 1200. In an embodiment, the safety sensor can be include a motion detector 1230 and an audio receiver/transmitter 1240. Further, in some embodiments, the visual alert 1200 can generate a front signal arrow 1210 and a rear signal arrow 1220. In an embodiment, the safety sensor system may detect an upcoming intersection and the front signal arrow 1210 may indicate to the rider to take the appropriate turn at the intersection. In such an embodiment, the back arrow may indicate the turn the rider is about to make to another cyclist behind them or to a motor vehicle. In some embodiments, the audio receiver/transmitter 1240 can emit audio commands to the rider, for example "left turn ahead" to coincide with the display of the front arrow 1210 in front of the rider and the back arrow 1220 in back of the rider. In other embodiments, the rider can swipe their hand in front of the motion sensor 1230 to indicate a turn they expect to make. In such embodiments, the visual alert 1200 can generate appropriate front arrows 1210 and back arrows 1220 to indicate the expected turn the rider anticipates making.

[00117] In some embodiments, the visual alert 1200 can indicate to other cyclists and motor vehicles when the rider is slowing down. In an embodiment, the visual alert 1200 can indicate slowing down by displaying the arrows in a red light, similar to brake lights on a motor vehicle. In some embodiments, the visual alert 1200 can generate any range of symbols, characters, and/or numbers to indicate characteristics of the bike to other cyclists and motor vehicles around the bike. In an embodiment, the safety sensor can include automated signaling capabilities. In an embodiment, the rider can set a destination, for example in a smartphone GPS, at the beginning of a trip or cycling session. In one embodiment, the safety sensor can determine the intended cycling route and pre-program appropriate signals, front arrows and back arrows, to correspond with the anticipated turns to reach the destination. In some embodiments, the safety sensor can generate the appropriate front arrow and back arrow based on the intended destination independent of rider interaction. In such an embodiment, the safety sensor can generate arrows at intersections without a rider indicating which way they intend to turn.

[00118] In some embodiments, the front console 805 and the back console 850 each include at least two lasers 840, 860. In an embodiment, the two lasers 840, 860 can be placed at a length of about 5 feet from each other. A length can be selected, such that the proper angle is created to maximize the design's efficiency. For example, estimating the consoles would be about 3 feet above the ground, to detect cars from at least 15 feet behind and 5 feet to the left or right of the bicycle, an ideal angle was found to be about 37 degrees in between the two sensors

[00119] In some embodiments, the main component of both the front console 805 and the back console 850, can be an ultrasonic sensor or any kind of wave and light sensor which can detect approaching objects to the cyclist. In some embodiments, there will be a transceiver module integrated in the proximity sensor system 800 to send the data to the virtual coach system, for example the virtual coach system as described in FIG. 6. In an embodiment, the proximity sensor system 800 can be powered by batteries and controlled by an on/off switch. In some embodiments, the battery can be recharged by the power generated by the rider by applying force to the pedal. In an embodiment, to save energy, the proximity sensor can automatically turn on with a movement detector and will turn off when no movement is detected within a pre-determined range of time, for example 5 minutes.

[00120] In some embodiments, the front console 805 and the back console 850 may weigh no more than 0.6 lb. each. The proximity sensor system 800 features can be fabricated to fit onto any type bike model. In some embodiments, the electric components including lights and sensors can be of low energy consumption and can be fitted in a custom lightweight housing adaptable to all bike types. Additionally, in an embodiment, the proximity sensor systems 800 may include waterproof housing.

[00121] FIG. 9B depicts an illustration of the steps taken in one embodiment of a method 950 for monitoring and crash prevention for a rider during a cycling session. In a brief overview, the method 950 may include creating, by the safety sensor, a smart lane around a bike operated by a rider during a cycling session, the smart lane indicates a safe zone around the bike (960). The method may further include detecting, by the safety sensor, an object approaching the smart lane during the cycling session (970). The method 950 may further include generating, by the safety sensor, an alert to the rider of the bike to notify the rider of the approaching object (980).

[00122] In some embodiments, the method 950 may include creating, by the safety sensor, a smart lane around a bike operated by a rider during a cycling session, the smart lane indicates a safe zone around the bike (960). In some embodiments, the safety sensor s can interact with the laser lights, such as laser lights 840, 860 described above with respect to FIG. 9A, to increase the awareness of both the bike as well as any nearby drivers. For example, in an embodiment, the safety sensor may detect a nearby vehicle or external danger and will trigger a change in the laser lights' 840, 860 behavior (e.g., change in color, flashing lights, etc.). The operator of the vehicle may notice the change in the laser lights 840, 860 behavior and be alerted to the presence of the cyclist.

[00123] In some embodiments, the method 950 may include detecting, by the safety sensor, an object approaching the smart lane during the cycling session (970). In some embodiments, the safety sensor may detect an approaching object (e.g., a vehicle) within a certain distance from the bike. FIG. 13A depicts an illustration of an embodiment of a range of detection 1300. In more detail, FIG. 13A depicts a bike 1310 with a car 1330 approaching. The safety sensor 1320 of the bike 1310 detects the car 1330 as it approaches and can alert the rider through various types of alerts and signals. In one embodiment, the safety sensor 1320 can detect the car 1330 when it is fifteen feet behind the bike 1310 and five feet away. In such an embodiment, lasers on the safety sensor 1320 can be placed at an angle of 16.20 degrees to detect the car 1330. In some embodiments, the angle of the lasers and the range of detection of the safety sensor 1320 can depend on the desired range and be fabricated to meet such a range.

[00124] FIG. 13B depicts an illustration of an embodiment of a laser range of detection 1350 . In more detail, FIG. 13B depicts a bike 1360 and a laser 1370. In some embodiments, the average height of a seat on the bike 1360 can be about three feet from the ground.

Accordingly, in an embodiment, to have a five foot wide smart lane, the lasers 1370 of the safety sensor can be placed at a 40 degree angle from the y-axis. As illustrated in FIG. 13B, the lasers 1370 can generate a smart lane behind the bike 1360 with a width of five feet when they are placed at a 40 degree angle from the y-axis. In some embodiments, the lasers 1370 can be placed at various angles to produce a smart lane of varying sizes.

In an embodiment, a detection distance may be pre-determined. In one embodiment, the rider may enter the detection distance prior to a cycling session via a user interface. In other embodiments, the detection distance may be entered by an administrator during manufacture. In response, the safety sensor may trigger a change in the light emitted from at least one of the laser lights. For example, in some embodiments, the safety sensors can detect a motor vehicle within a pre-determined distance from the left side of the bike. In some

embodiments, the safety sensor can compare current bike characteristics to a detected change in a cycling route condition to identify a dangerous situation. For example, in one embodiment, the safety sensor may compare a current bike speed to a map of the road the rider is cycling on. Based on the comparison, the safety sensor may determine the rider is going too fast for an upcoming turn. In other embodiments, the safety sensor may detect a change in a road condition. The change in the road condition may include at least one of a pothole and a change in elevation of the road, for example a bump in the road.

[00125] In some embodiments, the safety sensor system can detect when another rider (i.e., cyclist) is approaching in a blind spot or when a vehicle is coming out of a drive way. In an embodiment, the smart lane can save the cyclist response time when a vehicle is approaching and also alerts vehicles when the cyclist is going to turn. In some embodiments, the system can teach a rider to slow down at intersections and show them if they are a safe rider. In an embodiment, the system can serve as a communication device with cars showing the cyclist's location in the car's GPS system. In some embodiments, the safety sensor can be coupled to many types of vehicles, including at least one of a motorcycle and a motor vehicle. In an embodiment, the safety senor can collect and analyze data related to many types of vehicles including at least one of a motorcycle and a motor vehicle.

[00126] In some embodiments, the method 950 may further include generating, by the safety sensor, an alert to the rider of the bike to notify the rider of the approaching object (980). In an embodiment, the safety sensor can generate a visual alert to the rider using the laser lights to alert the rider of the dangerous situation. In one embodiment, generating the visual alert may include emitting, by the laser lights, a red lane instead of a green lane on the side of the approaching object to alert. In some embodiments, the laser lights may emit flashing lights to alert the rider of the incursion.

[00127] In some embodiments, the proximity sensor may generate an audio alert to the rider. In an embodiment, the safety sensors can determine if a vehicle is invading the rider's personal lane (e.g., the smart lane). In some embodiments, when the safety sensors can detect an incursion, the rider's personal lane will start flashing and the speaker from the front console can make a sound alerting the cyclist to move away.

[00128] In some embodiments, the safety sensor system may be communicatively coupled to a GPS system. In an embodiment, the GPS system can be a component of the safety sensor. In some embodiments, the safety sensor can detect a change in a cycling route condition by interacting with the GPS system. In an embodiment, the change in the cycling route condition may include upcoming changes in a road or street configuration (e.g., an intersection, sharp turn, rotary, construction, pothole, speed bump, etc.). In an embodiment, the GPS system can be a mapping application, such as Google Maps distributed by Google, Inc, executing on a portable computing device, such as an IPHONE mobile device manufactured by IPHONE, Inc. In some embodiments, the safety sensor may generate at least one of an audio, visual, and a tactile alert to the rider in response to detecting an upcoming intersection.

[00129] In one embodiment, the safety sensor may further include a vibration device. In some embodiments, the vibration device may be coupled to the handlebars of the bike. In an embodiment, the safety sensor may transmit a signal to the vibration device to cause the vibration device to vibrate the handlebars and alert the rider of the upcoming intersection. In some embodiments, the safety sensor can compare current bike characteristics to a detected change in a cycling route condition. For example, in one embodiment, a current bike speed can be measured. In response to detecting an upcoming intersection, the safety sensor can vibrate the handle bars to alert the rider to slow down. In an embodiment, a vibrator in communication with the safety sensor can vibrate the handle bars in response to a trigger event from the safety sensor. The trigger event may be in response to a detection of an approaching danger. In some embodiments, the trigger event may be an approaching object, for example a motor vehicle, a motorcycle, or another cyclist. In other embodiments, the trigger event may include a dangerous situation. The dangerous situation may include at least one of an upcoming intersection in the road and a sharp turn in the road.

[00130] In some embodiments, the safety sensor may further include a helmet monitoring system. In such an embodiment, safety sensors, similar to those illustrated in FIGS. 8A and 8B can be coupled to the rider's bike helmet. In some embodiments, these helmet sensors can monitor the rider's surroundings and provide feedback to the rider via a small speakers or headphones. In an embodiment, the speakers can alert the rider of events that are happening within a close range such as "car approaching on the left side". One of the benefits of this concept is that it would encourage cyclist to wear his or her helmet always.

[00131] FIG. 1 1 depicts an illustration of an embodiment of a safety sensor system 1100. In some embodiments, the safety sensor system 1 100 can operate similar to the safety sensor 1000, however the placement of the components may be different. In an embodiment, the safety sensor system 1100 can include four proximity sensors 1 120 and two speakers 11 10. In such an embodiment, the proximity sensors 1 120 may be placed on the outside of a chainring or cog set of the bike 1130 to cover both sides of the bicycle. In some

embodiments, the four proximity sensors 1120 can be used to determine if any car is approaching the bicycle 1 130 and how close it is similar to those described above with respect to FIG. 8A and 8B. In an embodiment, the proximity sensors 1 120 may work with the speakers 1 1 10 to help warn the cyclist by generating an audio alert. In some embodiments, the speakers 1 110 can be programmed so that as the car gets closer, the speaker 1 110 can start to emit sound with shorter intervals. In an embodiment, the safety sensor 1100 can warn the rider if they are in possible danger and/or if the car may invade their personal space (e.g., within the smart lanes boundaries). Further, the safety sensor 1100 can warn people around them (e.g., other cyclists, runners, walkers) to alert them to move further away from the car.

[00132] In some embodiments, a safety sensor can include a "safety officer application" to collect the information from the crash detection module and provide advice/recommendations to the rider indicating a risk factor related to the rider's performance. In an embodiment, the safety office application may be executing on a hand held computing device or a wearable computing device. In some embodiments, the safety officer application can transmit and receive information and data from the safety sensor.

[00133] In some embodiments, the safety sensor can include a real-time feedback via leftVight horns (or haptic/visual feedback by smartphone), to show the direction of the approaching dangerous object. For example, in the case of a "dangerous" approaching object to the bicycle, the horns can alarm and warn the rider to react. In some embodiments, the dangerous approaching object can be defined as a quick movement of two objects to each other that can potentially result in a crash. In an embodiment, the left/right horns can respond depending the position of the dangerous object, such as a vehicle. In some embodiments, based on the horn sound, the rider can have a few milliseconds to react and at least reduce the crash intensity. In an embodiment, the horn can be loud enough to be heard by the driver of the other vehicle as well.

[00134] In another embodiment, the safety sensor can include an off-line feedback via smartphone application (i.e. "safety office"), to educate individuals on their cycling behavior (i.e. how risky they drive and what the chance of accident was in the past 30 days).

[00135] This system can also be realized as a bi-directional transceiver module between the cyclist and the other drivers. So when they approach dangerously to each other, in addition to the cyclist the car driver also receives the warning feedbacks via the appropriate medium implemented in his personal car.
