The system also includes a distance sensor coupled to the frame and communicatively coupled to at least one of the one or more processors. The distance sensor is operable to measure a distance between the sensor and an object. The system further includes a speed sensor coupled to the frame and communicatively coupled to at least one of the one or more processors. The motorized stroller system's one or more processors are operable to receive a distance measurement from the distance sensor, receive a speed measurement from the speed sensor, and determine, based at least in part on the received distance measurement and the received speed measurement, whether to apply the brake.
Certain embodiments of the present disclosure may provide one or more technical advantages. A technical advantage of the present disclosure is that the motorized stroller system may include a safety line with an operator connection and a stroller connection and a safety sensor with a control unit that measures the force exerted on the stroller connection. The control unit may communicate with the motor to slow the stroller down in the event the safety line detaches from the stroller connection. In some instances, motorized stroller system includes a temperature control system that regulates the temperature of air in the housing unit. Another technical advantage is that the motorized stroller system may include a running program that can measure the distance traveled by the stroller frame. In some embodiments, the motorized stroller system includes a flare connected to the stroller frame. The flare may ignite in extenuating circumstances, such as when a motorized vehicle comes within a certain distance of the stroller.
A further technical advantage of motorized stroller system is that it may include a camera connected to the stroller frame and operable to record real-time images of the rider in the housing unit. The camera may generate a signal to the operator's electronic display to provide the operator with a constant visual of the rider. In some instances, motorized stroller system includes audio receivers connected to the stroller frame that broadcast audio signals to the operator and rider so that the operator and rider may orally communicate with one another. Additionally, motorized stroller system may include one or more housing units connected to the stroller frame that enable the operator to transport one or more additional children.
Other technical advantages of the present disclosure will be readily apparent to one skilled in the art from the following FIGURE, descriptions, and claims. Moreover, while specific advantages have been enumerated above, various embodiments may include all, some, or none of the enumerated advantages.



BRIEF DESCRIPTION OF THE DRAWINGS
To provide a more complete understanding of the present invention and the features and advantages thereof, reference is made to the following description taken in conjunction with the accompanying drawing, in which:
FIG. 1 illustrates an example motorized stroller system and apparatus according to certain embodiments of the present disclosure.



DETAILED DESCRIPTION
Embodiments of the present invention and its advantages are best understood by referring to FIG. 1 of the drawing, like numerals being used for like and corresponding parts of the drawing.
Stroller operators must manually push the stroller frame while exercising or moving about to propel the stroller forward. Stroller systems, particularly those used for jogging, tend to be heavy, and the energy required to push the stroller, especially a stroller accompanying a child, can cause undue fatigue and weariness. In addition, pushing a stroller often leads to poor posture, which over time can lead to pain, discomfort, and injury. Moreover, jogging while pushing a stroller may cause the operator's stride to impact the stroller or may force the operator to reduce their stride length to avoid impacting the stroller.
In certain embodiments, a motorized stroller system includes a stroller frame, one or more housing units connected to the stroller frame, three or more wheels, one or more sensors connected to the stroller frame and/or housing units, a temperature control system for the housing unit, a running program operable to measure the distance traveled by the stroller frame, and one or more devices coupled to the stroller frame or housing unit, such as a flare, a camera, a speaker system, or a step.
FIG. 1 illustrates an example motorized stroller system 100 according to certain embodiments of the present disclosure. In an embodiment, system 100 includes stroller frame 102, three or more wheels 104, one or more housing units 106 connected to frame 102, motor 108, one or more brakes 110, one or more processors 172, and one or more devices coupled to stroller frame 102 or housing unit 106, such as user electronic display 152, rider electronic display 162, distance sensor 116, speed sensor 118, temperature control system 124 for housing unit 106, heart rate sensor 126, flare 128, camera 130, audio receiver 132, speaker 134, and step 113.
Frame 102 represents a structure operable to accommodate rider 160 and one or more components of system 100. Frame 102 may be comprised of any suitable material, such as steel, aluminum, plastic, fiberglass, or a combination thereof. In some embodiments, frame 102 includes rods, hinges, axles, hand grip bar or handles 136, and a support for an underneath storage compartment. Hand grip bar or handles 136 are adjustable to accommodate the height of operator 150 in some instances.
Further, in some examples, hand grip bar or handles 136 may support a console or a drink holder.
In some embodiments, frame 102 may be folded for compactness. For example, operator 150 may retract or expand frame 102 by pushing a release button or by turning a handle or a hand grip bar to release hinged connections. In some instances, a locking mechanism may secure frame 102 in either its compacted or expanded position. One purpose of the locking mechanism is to prevent the stroller from accidentally closing when in use.
Wheel 104 represents a component coupled to frame 102 that rotates about one or more axes. Wheel 104 is generally circular in shape but can be any shape or size. Frame 102 may be supported by three or more wheels 104. For example, eight wheels 104 may support frame 102 to improve maneuverability over uneven or rough surfaces. In some embodiments, wheel 104 includes a rim, a hub, and spokes. Further, wheel 104 may include a suspension system to allow relative motion between the stroller's frame and the wheel. For example, the suspension system may allow one wheel to move independently from the other wheels. The suspension system helps absorb vibration and shock from the surface, thus contributing to the handling of operator 150 and the comfort of rider 160. Further, in some embodiments, one or more wheels 104 swivel for improved maneuverability. In some particular embodiments, one or more wheels 104 lock to impede rotation and thus provide better stability. In some instances, only the back wheels are locked, allowing the front wheels 104 to swivel. Wheels 104 may be comprised of any suitable material, such as rubber or plastic.
Housing unit 106 represents a structure operable to accommodate one or more riders 160. In some embodiments, frame 102 accommodates housing unit 106 in a forward-facing direction. In some specific embodiments, frame 102 may adjust to accommodate forward-facing housing unit 106 in one or more reclined positions. Additionally, frame 102 may accommodate housing unit 106 in a rear-facing direction, and in some particular instances frame 102 may adjust to accommodate rear-facing housing unit 106 in one or more reclined positions. In other embodiments, housing 106 comprises a reversible seat, and frame 102 accommodates the reversible seat in both the forward-facing and rear-facing directions. Further, frame 102 may accommodate more than one housing unit 106.
In some instances, housing unit 106 comprises an independent transport device that can be removed from frame 102, such as a car seat. For example, frame 102 may provide snaps, buttons, Velcro®, or some other mechanism to secure the removable housing unit in place. In some instances, frame 102 may support the removable housing unit in either a rear-facing or forward-facing direction. Additionally, frame 102 may support more than one removable housing unit.
Housing unit 106 may consist of any suitable material, for example, one or more of plastic, rubber, fabric, or nylon. In some embodiments, housing unit 106 is adjustable to accommodate riders of different sizes (e.g., infant, toddler, etc.). For instance, housing unit 106 may be comprised of components operable to expand to different sizes (e.g., fabric, Velcro®, snaps, buttons), modular components that support adding or removing portions of housing unit 106 to increase or decrease the size (e.g., expanded polystyrene foam), or other structure or material that allows housing 106 to dynamically increase or decrease in size (e.g., viscoelastic polyurethane foam).
In certain embodiments, housing 106 may comprise one or more different materials. For example, all or a portion of the housing unit 106 may comprise a structurally solid material (e.g., plastic, fiberglass, metal). Additionally, all or a portion of housing unit 106 may be comprised of a flexible material (e.g. fabric). In some embodiments, housing unit 106 includes a combination of two or more of the aforementioned materials. Different riders may benefit from different configurations. For example, small riders such as infants that require extra support may benefit from a structurally solid housing unit encased in fabric, whereas larger riders such as toddlers may benefit from an all-fabric housing unit that allows for more movement. Further, housing unit 106 may include an adjustable 3-point or 5-point harness to secure the child to housing unit 106. In some examples, the harness includes nylon straps, plastic buckles, and metal clips.
In some embodiments, housing unit 106 is an enclosure. The enclosure may be adjustable by a zippers, snaps, or any other suitable fasteners. In some particular embodiments, the material covering the enclosure is transparent to provide rider 160 visibility to the outside environment. Additionally, the material covering the enclosure may be opaque (e.g., cloth, flexible plastic, etc.). In other embodiments, housing unit 106 is open to the environment. Housing unit 106 may include a sun visor or a shade to shield rider 160 from ultraviolet (UV) rays. Further, housing unit may be comprised of waterproof or water resistant materials.
Motor 108 represents a power unit operable to impart motion to stroller frame 102. Motor 108 may be coupled to frame 102 and/or to one or more wheels 104. In some embodiments, motor 108 is an electric motor. In some particular embodiments, motor 108 is a DC electric motor powered by one or more batteries. Motor 108 may power only the rear wheels of motorized stroller system 100 in some instances, reserving the front wheels for steering. Additionally, motor 108 may power only the front wheels of motorized stroller system 100. In another embodiment, motor 108 powers both the rear and front wheels, or a combination thereof.
Brake 110 represents an apparatus configurable to slow, stop, or park the stroller. In some embodiments, brake 110 applies force directly to one or more wheels 104 to slow frame 102. For example, brake 110 may comprise a lever that presses a friction plate against one or more rear wheels 104. In another embodiment, brake 110 functions by decreasing power to motor 108, thus allowing frame 102 to decelerate. Some embodiments of motorized stroller system 100 include a safety brake that automatically or manually slows or stops wheels 104 in the event operator 150 separates more than a specified distance, for example three feet, from frame 102. Motorized stroller system 100 may also include a parking brake that prevents wheels 104 from rotating, thus securing frame 102 in a stopped position.
Electronic display 152 represents a device operable to present information to at least operator 150. Electronic display 152 may be coupled to frame 102 and communicatively coupled to at least one of the one or more processors 172. In some instances, electronic display 152 presents information such as time, speed, route, map, distance traveled, calories burned, the song playing, and/or a video of rider 160 in the stroller. For example, electronic display 152 may show operator 150 a video of rider 160 in real time to assure operator 150 that rider 160 is safe. In some embodiments, display 152 is located on the hand grip bar or handles. Electronic display 152 may also be positioned on an operator console or on any other suitable part of frame 102.

In some embodiments, electronic display 162 is positioned on a rider console or on any other suitable part of frame 102. In some embodiments, electronic display 162 is a screen, such as an LED, LCD, or plasma screen. In some particular instances, the display screen may be curved.
Distance sensor 116 represents a device operable to detect the presence of objects 140 within a specified range of the sensor. For instance, distance sensor 116 may emit an electromagnetic radiation beam (e.g., infrared) or an electromagnetic field to detect the presence of nearby objects 140. Distance sensor 116 may couple to frame 102, wheels 104, and/or housing unit 106. In certain embodiments, distance sensor 116 can determine the distance between frame 102 and object 140 obstructing the path of the stroller, such as a boulder. Further, in some embodiments distance sensor 116 can determine the distance between frame 102 and a moving object, such as a bicycle or a motorized vehicle, and sound an alarm when distance between rider 160 and object 140 is less than a specified length, such as five feet. In some instances, distance sensor 116 detects the curvature in the path and/or traffic. Distance sensor 116 may include a communication port (e.g., USB port) communicatively coupled to one or more of frame 102, wheel 104, housing unit 106, motor 108, or brake 110.
In some embodiments, distance sensor 116 may generate a command to change the speed of motorized stroller system 100. For instance, distance sensor 116 may send a command to motor 108 to slow frame 102 when the stroller comes within a specified threshold of object 140. In some specific embodiments, the distance threshold may vary depending on the target object. For example, object 140 such as a butterfly may have no distance threshold, allowing the stroller to come into contact with the butterfly without altering the stroller's speed. However, a larger object may have a larger distance threshold. For example, if frame 102 comes within three meters of a wall, distance sensor 116 may send a response to motor 108 to slow frame 102. Further, distance sensor 116 may be operable to sound an alarm when object 140 enters a specified threshold.
Speed sensor 118 represents a device operable to measure the speed of frame 102. In a particular embodiment, speed sensor 118 may determine the speed of frame 102 by using the rate of rotation of one or more wheels 104. Additionally, speed sensor 118 may determine the speed of frame 102 by communicating with a Global Positioning System (GPS) device. Speed sensor 118 may couple to frame 102, wheels 104, and/or housing unit 106. Further, speed sensor 118 may include a communication port (e.g., USB port) communicatively coupled to one or more of frame 102, wheel 104, housing unit 106, motor 108, or brake 110.
Pressure sensor 120 represents a device operable to measure pressure from operator 150. Pressure sensor 120 may be coupled to stroller frame 102 (e.g., hand grip bar) or to a hand-held device (e.g. remote control device). In other examples, pressure sensor 120 may be coupled to an article of clothing (e.g., shirt, wristband) of operator 150. In some embodiments, changes in pressure detected by sensor 120 operate to change the direction of motorized stroller system 100. For example, operator 150 may apply pressure to a button on a hand-held device to turn wheels 104.
Temperature control sensor 122 represents a device operable to measure the temperature of an object (e.g., housing unit 106). For example, temperature control sensor 122 may monitor the temperature of housing unit 106 until the ambient temperature of housing unit 106 equals the preset temperature. In some embodiments, temperature control sensor 122 is preset by operator 150 before using stroller system 100. Additionally, temperature control sensor 122 may be adjusted by operator 150 while stroller system 100 is in use. Further, temperature control sensor 122 may be permanently set to a specified temperature. Temperature control sensor 122 may be coupled to housing unit 106, frame 102, or on any other suitable part of stroller system 100.
In some embodiments, housing unit 106 includes a temperature control system 124 operable to regulate the temperature of air in the housing unit. Temperature control system may include a temperature control sensor 122, a heater operable to emit hot air into housing unit 106, and/or a cooler operable to emit cool air into housing unit 106. In some instances, temperature control sensor 122 may communicate with temperature control system 124 to shut off the heater if the temperature falls within a certain range, for example above 78 degrees Fahrenheit. Similarly, temperature control sensor 122 may communicate with temperature control system 124 to shut off the cooler if the temperature falls within a certain range, for example below 70 degrees Fahrenheit.
Heart rate sensor 126 represents a device operable to measure the heart rate of an operator 150 or rider 160. In some embodiments, heart rate sensor 126 is coupled to frame 102 or a hand-held device and reads the heart rate of operator 150 when operator 150 makes contact with the sensors. In some instances, heart rate sensor 122 may include a control that adjusts the intensity of the workout of operator 150 based on the heart rate of operator 150, for example adjusting the speed of motorized stroller system 100.
Sensors are not limited to the aforementioned sensors and may measure other variables such as position, motion, connectivity, moisture, various wavelengths of light (e.g., infrared, visible, and/or ultraviolet), various wavelengths of sound (e.g., ultrasonic and or infrasonic), particle concentration (e.g., contaminants in air), or any other measurement suitable for motorized stroller system 100.

Similarly, audio receiver 132 may receive an audio signal from operator 150 and a speaker 134 may broadcast the audio signal to rider 160. The one or more audio receivers 132 and the one or more speakers 134 may be coupled to stroller frame 102, housing unit 106, or any other suitable component of stroller system 100.
Step 113 represents a device connected to stroller frame 102 and operable to support the weight of operator 150. In some embodiments, step 113 may provide a support for operator 150 to rest a leg on top of (e.g., for stretching) while stroller system 100 is not in motion. In some embodiments, operator 150 may climb onto step 113 such that one or more feet of operator 150 no longer touch the ground. This may allow operator 150 to take a break from the current walk or run without requiring stroller system 100 to stop any movement or travel. In some embodiments, step 113 may be connected to stroller frame 102 on the same side as hand grip bar 136, such that it is present on the side of frame 102 on which operator 150 may primarily be. Step 113 may include a hinge and a clasp, such that it may be folded and clasped to frame 102. This may ensure that it does not extend into the stride of operator 150 while stroller system 100 is in motion and operator 150 is walking and/or running behind stroller system 100.
In certain embodiments, one or more components of system 100 (e.g., motor 108, brake 110, electronic operator display 152, electronic rider display 162, distance sensor 116, speed sensor 118, temperature control system 124, heart rate sensor 126, flare 128, camera 130, audio receiver 132, speaker 134, operator display 152, rider display 162, or any other suitable component) may communicate (via wireless or wireline communication) with one or more control units 170. Control unit 170 may include one or more computer systems at one or more locations. Control unit 170 may include any suitable combination of software, firmware, or hardware.

In some embodiments, control unit 170 determines whether to apply brake 110 based on a received distance measurement and a received speed measurement. Distance sensor 116 may determine the distance between object 140 and distance sensor 116. Object 140 may be a boulder, another stroller, a wall, a light post, or any obstruction that may cause harm if stroller system 100 becomes too close or even hits object 140. For example, distance sensor 116 may determine that it is 10 feet away from object 140. Distance sensor 116 may transmit the measured distance to control unit 170. Speed sensor 118 may measure the speed of frame 102. For example, speed sensor 118 may determine the frame 102 is moving at 3 miles per hour. Speed sensor 118 may transmit the measured speed of frame 102 to control unit 170. Control unit 170 may determine whether to apply brake 110 based on the distance measurement and speed measurement transmitted by distance sensor 116 and speed sensor 118, respectively. Control unit 170 may have thresholds for each measurement that must be exceeded before determining to apply brake 110. For example, if frame 102 is within 10 feet of object 140 and frame 102 exceeds 2.5 miles per hour, control unit 170 may determine to apply brake 110. As another example, if frame 102 is within 2 feet of object 140 and frame 102 has a current speed of 0 miles per hour, control unit 170 may determine not to apply brake 110. By basing the determination on the distance measurement and/or speed measurement, control unit 170 determines to apply brake 110 in situations where object 140 may pose a threat to stroller system 100.
In some embodiments, control unit 170 determines to apply brake 110 based at least in part upon the determination that safety line 111 engaged switch 112, the speed measurement, and a maximum deceleration rate. Operator 150 may attach safety line 111 to the clothing of operator 150 or may hold safety line 111 in the hand of operator 150. Operator 150 may move at slower speed than stroller system 100 and, at a certain distance away from stroller system 100, safety line 111 may engage switch 112. If switch 112 is or has been engaged, control unit 170 may determine to apply brake 110. In certain embodiments, control unit 170 may want to ensure stroller system 100 does not come to an abrupt stop, but rather gradually slows down and stops. Control unit 170 may assess the speed of frame 102 (as determined by speed sensor 118) and, based on a maximum deceleration rate (e.g., one based on speed and determined to be a comfortable rate), apply brake 110 such that stroller system 100 slows down and/or stops moving.
In some embodiments, operator 150 uses pressure sensor 120 to change the direction of movement of stroller system 100. Operator 150 may vary the pressure applied to pressure sensor 120 (e.g., by the hand or finger(s) of operator 150) to communicate to change the direction of stroller system 100. For example, operator 150 may press on the right side of pressure sensor 120 to indicate that stroller system 100 should veer to the right. In response to the pressure on the right side of pressure sensor 120, one or more wheels 104 may turn such that stroller system 100 veers to the right of its current direction. In some embodiments, how far in one direction the wheels turn may depend upon the intensity of the pressure, the length of time the pressure is applied, and/or the amount of individual presses operator 150 applies to pressure sensor 120. By using pressure sensor 120 to change the direction of stroller system 100, operator 150 may limit the amount of energy used to steer and turn stroller system 100, thus limiting cause undue fatigue and weariness.
In some embodiments, control unit 170 may ignite flare 128 to send a warning signal to other persons, alerting them of presence of stroller system 100. Control unit 170 may receive a distance measurement from distance sensor 116. For example, if stroller system 100 ends up in the middle of a road, distance sensor 116 may determine object 140 (e.g., a car, bicycle, truck, runner) is within a certain distance (e.g., 10 feet) of stroller system 100. Continuing the example, control unit 170 may determine object 140 is a high-risk object and ignite flare 128. Control unit 170 may ensure that flare 128 ignites in a direction opposite from stroller system 100 and object 140 such that flare 128 will not hit either. The ignition of flare 128 alerts other people (e.g., the driver of a car, a cyclist, a truck driver, a runner) of the presence of stroller system 100. Flare 128 serves as a safety mechanism so that other people may ensure they do not hit stroller system 100 with object 140 (e.g., car). Control unit 170 may ignite flare 128 in addition to applying other safety mechanisms, such as applying brake 110 and/or changing the direction of stroller system 100.
In some embodiments, control unit 170 may present information to operator 150 regarding the workout of operator 150. In one embodiment, heart rate sensor 126 may determine the heart rate of operator 150 and control unit 170 may present the heart rate measurement to operator 150 on operator display 152. This may be beneficial so that operator 150 is aware of the heart rate of operator 150, for example, if operator 150 is working out and wants the heart rate to be within a certain range. In one embodiment, control unit 170 may determine a distance traveled by stroller system 100 and present the determined distance on operator display 152. Control unit 170 may determine the distance traveled based on the rate of rotation of one or more wheels 104 and/or by communicating with a Global Positioning System (GPS) device. This presentation of the distance traveled may be beneficial to operator 150, for example, if operator 150 has a goal mileage to travel within a certain time frame (e.g., a day, a week, a month, a current run and/or walk). By presenting heart rate and distance traveled information to operator 150, stroller system 100 ensures that operator 150 meets any exercise or fitness goals while transporting rider 160.
Although a particular implementation of system 100 is illustrated and primarily described, the present disclosure contemplates any suitable implementation of system 100, according to particular needs. Moreover, although the present invention has been described with several embodiments, diverse changes, substitutions, variations, alterations, and modifications may be suggested to one skilled in the art, and it is intended that the invention encompass all such changes, substitutions, variations, alterations, and modifications as fall within the spirit and scope of the appended claims.
