CURB POWER SOURCE

The present disclosure is directed to a curb for providing electricity to one or more devices on a street or a sidewalk. The curb includes a rigid curb housing for storing at least one power source or power source connector configured to be electrically coupled to a power source. The curb additionally includes a top plate removably attached to the rigid curb housing, the top plate configured to electrically couple at least one power outlet to the at least one power source or power source connector.

FIELD OF THE DISCLOSURE

This disclosure relates to curbs and applications for said curbs. More particularly, this disclosure relates to curbs that provide electricity to one or more devices on a street or a sidewalk.

BACKGROUND

Curbs are typically installed at the perimeter of a street to delineate the edge of the street from a sidewalk or street median adjacent to the street. A curb may enhance safety by redirecting low-speed motor vehicle traffic; may provide structural support to the street pavement; may reduce erosion risk by channeling runoff water from rain or melted snow into storm drains; may alert a pedestrian to stop or slow down as they approach the street; and/or may enhance an aesthetic appeal of the street. Traditional curbs are made of materials including asphalt, stone or masonry blocks, and concrete. In addition, these traditional curbs are solid rather than hollow.

SUMMARY

Currently, there is no safe, efficient way to distribute power to devices on a street or sidewalk. In suburban and rural areas, power is usually transmitted to buildings or streetlights via overhead power lines, and in urban areas or environmentally sensitive areas, power is usually transmitted to buildings or streetlights via underground power lines. While the space in which to run power lines has not risen (e.g., in cities, the space in which to run power lines is often limited by preexisting underground pathways), the need to power devices located outdoors has risen—increasing demand from new outdoor power consumption devices (e.g., lighting for outdoor restaurants, electric vehicles, and smart devices such as augmented reality headsets) has been coupled with demand from traditional power consumption devices (e.g., food tucks, cameras for film crews, construction equipment, billboards, and machinery for agriculture systems). Further, the demand from indoor power consumption devices (e.g., cooling and heating systems, home appliances, computers, and electric lights) has risen along with the increasing demand from outdoor power consumption devices.

Thus, electrically charging/powering a device (e.g., a vehicle) on a street or sidewalk currently can only be achieved in a limited capacity, and is usually achieved by running a cable from a building to the device. However, this method of charging/powering a device may be inefficient and/or infeasible in areas in which no buildings or few buildings are present; may result in safety concerns in areas in which traffic—whether pedestrian or vehicle—must frequently cross; and may result in costly code violations, fire hazards, and/or weather damage to the unprotected cable. Additionally, alternative methods to charge devices located outdoors, such as wireless charging, are very costly and are very inefficient, such that widespread adoption would require the work of tens, hundreds, or thousands of new power plants around the world.

Accordingly, Applicant has developed a curb that provides electricity to one or more devices on a street or sidewalk. Specifically, Applicant has developed a curb that is configured to electrically couple at least one power outlet located on a street-level or sidewalk-level to at least one power source or power source connector housed within the curb.

According to some embodiments, a curb for providing electricity to one or more devices on a street or a sidewalk is provided, the curb comprising: a rigid curb housing for storing at least one power source or power source connector configured to be electrically coupled to a power source; and a top plate removably attached to the rigid curb housing, wherein the top plate is configured to electrically couple at least one power outlet to the at least one power source or power source connector.

According to some embodiments, the rigid curb housing comprises a front side, a back side, and a bottom side.

Additional advantages will be readily apparent to those skilled in the art from the following detailed description. The examples and descriptions herein are to be regarded as illustrative in nature and not restrictive.

DETAILED DESCRIPTION

Applicant has developed a curb that can distribute power to devices on a street or sidewalk. The need to power devices located outdoors has risen as the need to power devices located indoors has also risen; however, the space in which to run power lines has not risen. Current solutions to deliver power to devices on a street or a sidewalk are neither scalable nor safe, as they (1) are inefficient and may require increased power generation at power plants; and/or (2) lead to increased fire hazards, tripping hazards for pedestrians, and weather damage that result from unprotected power lines. Accordingly, Applicant's curb can be configured to provide new pathways in which to distribute power to devices on a street or sidewalk. For example, Applicant's curb can distribute power from at least one power source or power source connector housed within the curb to at least one power outlet (or a set(s) of power outlets) on a street-level or sidewalk-level, and subsequently to one or more devices plugged into the power outlets. Distributing power through an electrified curb can provide a safe and efficient means to distribute power to devices on a street or sidewalk.

FIG. 1depicts an illustration of a segment of a street block100, according to some embodiments.FIG. 1includes an example of a street102; a sidewalk104; a curb106; a power station114comprising at least one first power outlet108and at least one second power outlet116. The at least one first power outlet108can comprise a first power outlet110and a second power outlet111, and the at least one second power outlet116can comprise a first power outlet118and a second power outlet119.FIG. 1additionally includes a moped112connected to power outlet110; a vehicle120connected to a power outlet (e.g., power outlet118); a building122; and a pedestrian124.

The curb (e.g., curb106) can provide electricity to one or more devices (e.g., moped112and vehicle120) on a street (e.g., street102) or a sidewalk (e.g., sidewalk104). According to some embodiments, the curb can be configured to electrically couple at least one power outlets (e.g., power outlets108) to at least one power source (e.g., a rechargeable battery, generator, etc.) or power source connector (e.g., a power cable that is electrically coupled to a power source). The curb can house the at least one power source or power source connector, and the at least one power outlet may be removably attached to a corresponding portion of the curb such that power may be distributed from the at least one power source or power source connector to the at least one power outlet. The curb may be installed adjacent to a street and/or sidewalk, such that the power outlets can be close to any device (e.g., an electric vehicle, a smart phone, a heater, and/or a projector) located near the street and/or sidewalk. Thus, a plurality of devices may be simultaneously plugged into the at least one power outlet such that they can be simultaneously charged/powered.

As shown, curb106can be installed between street102and sidewalk104, such that the curb separates the street from the sidewalk. Curb106can be installed such that the curb remains rigidly fixed in the ground. For example, a foundation for the curb may be dug into the ground, and a portion of a housing for the curb may extend into the ground (e.g., to a depth of at least 3 inches, at least 6 inches, at least 9 inches, at least 12 inches, at least 15 inches, or at least 18 inches), or the curb may be fastened to at least one support beam that extends into the ground.

The dimensions of curb106(e.g., a length, a width, and a height of the curb) may be customized. According to some embodiments, the dimensions of the curb may be customized based on the dimensions of one or more objects (e.g., a street or a sidewalk) adjacent to the curb, and/or based on the geographic area in which the curb is installed to conform with code rules pertaining to curbs for the geographic area. Further detail regarding the curb will be provided with respect toFIG. 2.

Curb106can house at least one power source and/or power source connector configured to provide electricity to at least one power outlet (e.g., power outlets108). A power source can be any power generation system (e.g., a power plant, a power generator, a battery (e.g., rechargeable battery), a wind turbine, a building power source, and/or a solar cell among others). According to some embodiments, some or all of the power may be provided by a renewable energy power source (e.g., a solar cell that harnesses solar energy, a wind turbine that harnesses wind energy, and/or a thermal pump that harnesses geothermal energy). A renewable energy power source may advantageously reduce dependency on fossil fuels, and increase air quality (e.g., by reducing dependency on diesel generators). According to some embodiments, a power source can be selected based on a requirement to provide tens, hundreds, or thousands of watts of power to the curb. A power source connector can be any connector (e.g., a power cable) configured to electrically couple a power source and at least one power outlet.

The at least one power outlet108can receive power from the at least one power source or power source connector, and can be used to electrically charge and/or power one or more devices. In some embodiments, a plurality of devices may simultaneously be connected to a plurality of power outlets, such that the plurality of devices simultaneously charge or are powered. The devices may be located on/near a street and/or a sidewalk adjacent to the power outlets. As shown inFIG. 1, moped112on street102is plugged into a power outlet110; another device may simultaneously be plugged into outlet111.

Moreover, as shown inFIG. 1, power outlets108may be comprised within power station114; according to some embodiments, power station114may comprise at least one power outlet on each of a front side and a back side of the power station (from the perspective of a pedestrian walking in the longitudinal direction of sidewalk104, the front side is the side closest to them and the back side is the side farthest from them). A power station that includes at least one power outlet on each of a front side and a back side can be advantageous at least because the power station may provide (1) more total outlets to consumers compared to a similarly sized power station which only comprises at least one power outlet on either a front side or a back side (this can be important especially in areas of high demand); and (2) outlets closer to a device being charged (this can be important at least to reduce power loss caused by transmitting power from an outlet to a device through a longer than needed path).

According to some embodiments, the at least one power outlet108can be housed within the front side of power station114, as depicted inFIG. 1, and the at least one power outlet116can be housed within the back side of power station114. For example, vehicle120on street102is plugged into an outlet (e.g., power outlet118) of the at least one power outlet116; similarly, another device may simultaneously be plugged into another outlet (e.g., power outlet119) of the at least one power outlet116. Thus, as shown inFIG. 1, power station114can simultaneously charge moped112and vehicle120.

The segment of a street block100can further comprise building122(the façade of which is shown inFIG. 1), and pedestrian124. As discussed above in the summary section, an alternative means to distribute power to one or more devices on a street or a sidewalk, other than via a curb power source, can involve running a cable from a building (e.g., building122) to a device (e.g., vehicle120). However, in addition to those reasons (e.g., inefficiencies and/or infeasibility in areas in which no buildings are present; costly code violations; fire hazards; and/or weather damage to the unprotected cable) enumerated in the summary section above, running a cable from building122to vehicle120can be disadvantageous at least because doing so poses a safety risk to pedestrian124. For example, if walking along sidewalk104, pedestrian124may easily trip over the exposed cable (especially if the sidewalk is crowded with pedestrians such that the cable is difficult to see and/or if the pedestrian is in a hurry).

FIG. 2depicts a zoomed-in illustration of a segment of a street block200, according to some embodiments. Street block segment200can include a street202(e.g., street102ofFIG. 1), a sidewalk204(e.g., sidewalk104ofFIG. 1), a curb206(e.g., curb106ofFIG. 1), a first power station218, and a second power station236.

As shown inFIG. 2, curb206can include a housing208. According to some embodiments, housing208may be configured to store at least one power source or power source connector. In some embodiments, at least one power source may be housed within the curb at least to reduce power losses caused by transmitting power over a long path. In some embodiments, at least one power source connector (e.g., a power cable that is electrically coupled to a power source) may be housed within the curb at least to provide a connection to a power source (e.g., a power plant or a wind turbine) that is not in the curb (e.g., it cannot fit within the curb). A plurality of power sources and/or a plurality of power source connectors may be housed within the curb to simultaneously distribute power to a plurality of power stations and/or power outlets, and subsequently to a plurality of devices.

According to some embodiments, housing208can be a rigid housing. In some embodiments, the rigid housing can be configured to be immovable and/or to serve as a barrier to low-speed motor vehicle traffic. The material composition, design, and/or dimensions of the housing may be selected to provide protection from motor vehicle traffic.

According to some embodiments, the material with which housing208is composed can enhance the rigidity of the housing. The rigidity of the housing can ensure safety of a power source or a power source connector within the curb. According to some embodiments, housing208can be composed of concrete, steel, aluminum, and/or copper. In some embodiments, steel may be selected based at least on its ability to mitigate rust, its impact resistance, and/or its ductility. According to some embodiments, housing208can be composed of reinforced or hardened steel. According to some embodiments, the curb housing can be designed to be in place for at least approximately 50 years before being replaced; the housing may need to be replaced due to material wear that decreases the rigidity of the curb, such that it can no longer provide adequate protection to the electrical components stored within the housing.

A height of the housing may be selected at least to serve as a barrier to motor vehicle traffic. According to some embodiments, the height of the housing (measured in a direction from the ground upward) may be at least 3 inches, at least 6 inches, at least 9 inches, at least 12 inches, at least 15 inches, or at least 18 inches above the level of street202, such that the housing can serve as a barrier to motor vehicle traffic yet is not excessively tall such that it is unnecessarily costly to manufacture and difficult for pedestrians (e.g., pedestrian124ofFIG. 1) to step over. Moreover,FIG. 2shows that a front side of the housing (the side of the housing adjacent to street202, hereinafter referred to as the “front side”) can be at a right angle relative to the ground; the verticality of the front side of the housing relative to the ground, coupled with the height of the housing, can advantageously allow the housing to serve as a barrier to low-speed motor vehicle traffic. Additionally, the verticality of the front side of the housing relative to the ground advantageously (1) can provide pedestrians (e.g., pedestrian124ofFIG. 1) with a straight step up or down, a straight step up or down being less likely to be tripped over; and (2) can enable manufacture of the curb to be easier, quicker, and cheaper (compared to if the curb were at an angle other than 90 degrees relative to the ground). In some embodiments, the curb can be at an angle other than 90 degrees relative to the ground.

The height of the housing may be customized. As shown inFIG. 2, the height of housing208may be configured such that the curb is flush to the level of sidewalk204when installed. As discussed above, according to some embodiments, the height of housing208may be at least 3 inches, at least 6 inches, at least 9 inches, at least 12 inches, at least 15 inches, or at least 18 inches above the level of street202. Although shown to be uniform throughout a length of the curb (measured in a direction from left to right as viewed inFIG. 2), the height of the housing may vary. For example, the height of the housing may be decreased in one or more regions along a length of the curb to provide access to a driveway or to make it easier for pedestrians (e.g., pedestrian124ofFIG. 1) to traverse crosswalks and other pedestrian crossings (e.g., such that the curb is just above the level of the street). Alternatively, the height of the housing may be increased in one or more regions along the length of the curb to provide greater protection from motor vehicle traffic (e.g., in areas with high pedestrian traffic and/or dangerous equipment, such as fuel pumps). According to some embodiments, the height of the housing can vary according to a gentle slope, such that when increasing in height, the curb curves up in a concave manner and when decreasing in height, the curb curves down in a convex manner.

Similarly, a width of the housing may be customized. As shown and described with respect toFIG. 2, curb206can be installed between a street (e.g., street202) and a sidewalk (e.g., sidewalk204). According to some embodiments, curb206can be installed between street202and sidewalk204such that housing208is adjacent to, but does not extend past, the street on the front side and the sidewalk on another side (hereinafter referred to as a “back side” of the housing); the width of housing208(measured in a direction extending from the front side to the back side of the housing) can, for example, be at least 6 inches, at least 12 inches, at least 18 inches, or at least 24 inches. The width of the housing may additionally be selected to provide sufficient storage room for the at least one power source or power source connector housed within the curb.

Although shown to be uniform throughout the length of the curb, the width of the housing may vary along the length of the curb (e.g., to widen in a region along the length of the curb which can be configured to provide access to a driveway, such that a motor vehicle may cross a sidewalk at a low speed to access the driveway; to remain adjacent to a street and a sidewalk if the street and/or the sidewalk narrows or widens; and/or to conform to code rules pertaining to the width if the rules change from one jurisdiction to another along the length of the curb).

Further, the length of the curb may be customized: the length of the curb may extend throughout only a portion of a street block, throughout an entire street block, or throughout a plurality of street blocks. A longer curb may advantageously be able to distribute power to more devices. However, a longer curb may be more difficult to manufacture and install; for example, as discussed above, the width of the housing may vary throughout the length of the curb. Moreover, a longer curb may be more costly to manufacture and install. Thus, it may be advantageous to manufacture and install the curb for only a portion of a street block (e.g., near parking spots for electric vehicles, or near an outdoor restaurant) for which device charging is most needed.

According to some embodiments, the length of the curb may be customized by designing the curb housing to be modular, such that one or more segments of the housing can be modified, added, and/or subtracted. For example, as shown inFIG. 2, housing208can comprise a first segment209and a second segment210. In some embodiments, first segment209and first segment210are two separate housings (e.g., first housing209and second housing210). Designing the curb housing to be modular can advantageously (1) increase flexibility of the length of the curb; (2) increase flexibility of the curvature of the curb; (3) reduce construction and installation time and cost; and/or (4) reduce maintenance time and cost. Each segment of the curb housing or each curb housing may be connected at one or more joints (e.g., joint246shown). The one or more joints can be configured to (1) provide support for the housing(s) and/or any objects placed on top of the housing(s); (2) allow for movement of housing(s) along a curve of road202; and/or (3) allow for a cutout in the front side of housing(s) for an inlet (e.g., a storm drain).

According to some embodiments, the rigid curb housing can comprise a rigid shell. According to some embodiments, the front side (i.e., side adjacent the street), the back side (i.e., side adjacent the sidewalk), and a bottom side (i.e., side resting in and on the ground) of the housing can be enclosed by the rigid shell. For example, as shown inFIG. 2, housing208can be a walled shell. According to some embodiments, a thickness of a wall of the shell can be at least 0.25 inches, at least 0.5 inches, at least 1 inch, at least 1.5 inches, at least 2 inches, at least 3 inches, or at least 4 inches. The thickness of a wall of the shell may be customized based at least on (1) the need to ensure that the shell remains rigid if impacted (e.g., by a motor vehicle), such that the at least one power source or power source connector housed within the curb remains protected; and/or (2) the desire to make the shell lightweight and/or easier or cheaper to manufacture. The thickness of each wall of the shell may be uniform, as shown, or may vary depending on the side of the shell or the region along the length of the shell (e.g., the thickness of the side adjacent to the street may be greater than that of the side adjacent to the sidewalk, or the thickness of the side adjacent to the street may be increased where the street curves sharply).

According to some embodiments, the housing or rigid shell comprises at least one aperture on its top side. In some embodiments, the at least one aperture may be configured to provide access or to the at least one power source or power source connector stored in the housing. In some embodiments, the at least one aperture may be configured to store the at least one power source or power source connector housed within the curb. Storing the at least one power source or power source connector within an aperture can provide increased flexibility compared to, for example, a housing designed to fit only a specific power source or power source connector.

The dimensions of an aperture may be customized based at least on the dimensions of the segment of the curb in which it is located. As shown inFIG. 2, aperture210can be configured to fit within segment209, and to take up a majority of volume of the curb segment; a larger aperture beneficially can provide more access and/or storage space for the at least one power source or power source connector, can enable the curb to be more lightweight, and can reduce material consumption. According to some embodiments, a width of aperture210(measured in the direction of the width of housing208) can be at least 2 inches, at least 3 inches, at least 4 inches, at least 5 inches, or at least 6 inches; a length of aperture210(measured in the direction of the length of housing208) can be at least 1 foot, at least 2 feet, at least 3 feet, at least 4 feet, or at least 5 feet; and a depth of aperture210(measured in the direction of the height of housing208) can be the thickness of the shell wall or at least 3 inches, at least 6 inches, at least 9 inches, at least 12 inches, or at least 15 inches (e.g., so that the aperture extends to the ground). As shown, the longitudinal direction of aperture210can extend in the longitudinal direction of curb206. The dimensions of all apertures may be the same, or one or more dimensions of one or more apertures may vary.

According to some embodiments, an aperture can be manufactured via a milling process and/or via one or more stepped-extrusions. Manufacturing an aperture may require specialized tooling. Alternatively, the tooling used to manufacture an aperture may be rapidly reconfigurable, such that a tool may be used to manufacture a wide variety of parts in addition to an aperture.

According to some embodiments, the rigid shell or housing can include at least one aperture on a longitudinal end of the shell (e.g., on its right side, as shown inFIG. 2). As shown inFIG. 2, aperture228can be configured to provide access to or store at least one port (e.g., port230or port231) electrically coupled to a power source and/or at least one power source connector (e.g., power cable232) electrically coupled to at least one of the plurality of ports.

Moreover, as shown inFIG. 2, aperture228, and a corresponding section of curb206, can extend downward beneath ground level. Aperture228may extend downward beneath ground level at least to increase the ease of connecting preexisting underground data cables to the ports (e.g., power is transmitted underground in many urban areas). According to some embodiments, aperture228and a corresponding section of curb206can extend downward to a depth of at least 1 foot, at least 2 feet, at least 3 feet, at least 4 feet, or at least 5 feet. According to some embodiments, the depth to which the aperture and corresponding curb section extend may be customized based at least on the depth of power lines to which the curb connects and/or the number of ports aperture228is configured to store.

According to some embodiments, some or each of the ports may be configured to receive power from a power source. According to some embodiments, each of the ports may receive power from the same power source. According to some embodiments, some or each of the ports may receive power from a different power source. For example, a first power line carrying power from a first power plant may be electrically coupled to port230, and a second power line carrying power from a second power plant may be electrically coupled to port231. The diameter of a port may be determined based at least in part on the power source it is electrically coupled to, and/or the power load it is configured to receive.

Each of the ports may be comprised within a transformer. For example, as shown inFIG. 2, port230and port231are comprised within transformer229. A transformer may be configured to modify (e.g., to decrease (‘step down’) or to increase (‘step up’)) the power level received at the power outlet(s), based at least on the power the power outlet(s) is configured to transmit to one or more devices connected thereto; the settings of the transformer and/or the transformer used may be modified based at least in part on any modification to the power requirement of the power outlet(s). According to some embodiments, the curb comprises at least one transformer (e.g., transformer229and transformer233shown inFIG. 2); the transformer(s) may be configured such that different power outlets receive the same amount of power, or such that different power outlets receive different amounts of power.

A power source connector may be electrically coupled to a power source to distribute power received from the power source throughout the curb. For example, power cable232may be electrically coupled to port230and/or port231to distribute the power received at the port throughout the curb. According to some embodiments, power cable232can be designed to be used for approximately 10 years before being replaced; the power cable may need to be replaced due to material wear that decreases the insulation around the cable, rendering power transmission along the cable both less efficient and more dangerous.

According to some embodiments, power cable232may be electrically coupled to port230, and a second power source connector (e.g., a second data cable233) may be electrically coupled to port230; a second power source connector may be included at least to transmit power received from a second power source and/or to distribute power to another region of curb206.

According to some embodiments, a power source connector can distribute power throughout the curb by extending through one or more of the segments of the curb. For example, as shown inFIG. 2, power cable232can extend throughout first segment209of curb206by extending through aperture210; thus, aperture210may serve as an electrical conduit through which power is transmitted. According to some embodiments, power cable232may extend throughout second segment210in addition to first segment209. For example, there may be a cylindrical channel within joint246through which power cable232passes; according to some embodiments, the channel may be just large enough in diameter (e.g., 0.1 inches, 0.2 inches, 0.3 inches, 0.4 inches, or 0.5 inches) such that the power cable may pass through it, but not so large that the rigidity of the curb housing is compromised.

According to some embodiments, a top plate is removably attached to a corresponding curb housing or a segment of the curb housing. According to some embodiments, a protruding portion of the top plate can be configured to fit within an aperture on the top side of the curb housing. When attached, the top plate can provide a water-tight seal to protect the at least one power source or power source connector housed within the housing by enclosing a portion of the top side of the housing corresponding to the aperture. For example, as shown inFIG. 2, top plate212can be configured to removably attach to housing208, and a protruding portion214of top plate212can be configured to fit within aperture210. Configuring the top plate to removably attach to the curb housing can be advantageous for at least 2 reasons: (1) it can provide greater accessibility to the at least one power source or power source connector housed within the curb (e.g., to perform maintenance and/or to modify the power source or power source connector being used); and/or (2) it can provide greater flexibility to swap out a top plate with a different top plate (e.g., to replace a top plate that has been damaged and/or to replace a top plate with a top plate that is configured differently).

A top plate may removably attach to the curb housing in a number of ways. For example, similar to a manhole cover, the top plate may be locked in place and composed of a very heavy, strong material such that the plate is difficult to remove for unauthorized people without suitable tools. According to some embodiments, the top plate removably attaches to the top side of the housing via at least one fastener. A fastener may include any variation of a removable securing device, such as nuts and bolts, screws, pins, nails, any combination thereof, and/or the like. According to some embodiments, the top plate removably attaches to the curb housing via a press fit between the protruding portion of the plate and an aperture on the top side of the curb housing; to remove the top plate without causing damage to the plate, the plate may be cooled (e.g., below the freezing point of the material with which the plate is made) to allow it to shrink.

According to some embodiments, the dimensions of a top plate may be customized based at least in part on the dimensions of the aperture within which a portion of the top plate is configured to fit and/or the dimensions of the segment of the curb upon which a portion of the top plate is configured to rest. As shown inFIG. 2, the length and width of top portion213of top plate212can be selected based on the length and width of segment209, and the length, width, and depth of protruding portion214of top plate212can be selected based on the length, width, and depth of aperture210(all measurements made along the same directions as the corresponding length, width, and height measurements of housing208).

The depth of top portion213of top plate212may be selected to ensure the rigidity of the top plate, while minimizing the weight of the plate and the cost to manufacture the plate; the depth of protruding portion214of top plate212may be selected to ensure that the plate is securely attached to the housing, but that there is still room in aperture210underneath top plate212in which to store the at least one power source or power source connector. According to some embodiments, the depth of top portion213can be at least 0.25 inches, at least 0.5 inches, at least 1 inch, at least 1.5 inches, or at least 2 inches. According to some embodiments, the depth of protruding portion214can be one-eighth the depth of aperture210, one-quarter the depth of aperture210, one-half the depth of aperture210, or three-quarters the depth of aperture210.

As shown inFIG. 2, the length and width of protruding portion214of top plate212can approximately match (i.e., may be slightly different depending on the assembly method (e.g., press fit vs clearance fit)) the length and width of aperture210; this can advantageously allow for a secure attachment to the housing. The length of top portion213may be determined according to Equation 1 and the width of top portion213may be determined according to Equation 2.

where L213represents the length of top portion213, L210represents the length of aperture210, T208represents the thickness of a wall of housing208, and L246/2 represents one-half the length of joint246.

where W213represents the width of top portion213, W210represents the width of aperture210, and 2*T208represents twice the thickness of a wall of housing208.

According to some embodiments, protruding portion214can be a solid block of material. According to some embodiments, protruding portion214can be hollow, such that the at least one power source or power source connector within curb segment209can be housed within protruding portion214. In these embodiments, the thickness of one or more walls of protruding portion214may be at least 0.25 inches, at least 0.5 inches, at least 1 inch, or at least 1.5 inches.

According to some embodiments, the length or width of protruding portion214of top plate214may be smaller than the length or width of aperture210at least to provide more access or room for storage within the aperture. Moreover, although shown to be uniform along the length of the plate, the width of the top portion213and/or protruding portion214of top plate212may vary, at least to correspond to any variations in the width of the curb housing.

Each top plate may have the same dimensions, or one or more top plates may have one or more different dimensions. For example, the length of top portion245of top plate244, configured to enclose an aperture248corresponding to segment210, may be determined according to Equation 3.

where L245represents the length of top portion245of top plate244, L248represents the length of aperture248(not shown inFIG. 2), L246/2 represents one-half the length of joint246, and L250/2 represents one-half the length of joint250(the region of curb206at which segment210connects to another segment of the curb).

A different equation may be used to calculate the length of top portion245of plate244compared to the length of top portion213of plate212due to segment209being at an end of curb206and segment210being in between two other segments of curb206.

According to some embodiments, the material with which a top plate is composed can enhance the rigidity and mechanical strength of the top plate. The enhanced rigidity and mechanical strength of the top plate can ensure adequate protection of a power source or a power source connector comprised within a corresponding section of the curb. For example, according to some embodiments, top plate212can be composed of concrete, steel, aluminum, and/or copper; steel may be selected based at least on its ability to mitigate rust, its impact resistance, and/or its ductility. According to some embodiments, top plate212can be composed of reinforced or hardened steel. All top plates may be composed of the same material, or one or more top plates may be composed of a material other than the material with which top plate212is composed (e.g., if one segment of the curb is subject to greater forces).

According to some embodiments, a top plate can be designed to be used for approximately 1 to 5 years before being replaced; the top plate may need to be replaced due to material wear that decreases the rigidity and/or mechanical strength of the plate, such that it can no longer provide adequate protection to the at least one power source or power source connector stored within the corresponding section of the curb.

According to some embodiments, a top plate comprises an indentation configured to electrically couple at least one power outlet to at least one power source or power source connecter stored within a corresponding segment of the curb housing. For example, indentation216of top plate212can be configured to electrically couple power outlets220to at least one power source or power source connector within curb segment209. As shown inFIG. 2, power outlets220may be comprised within a power station218, and a portion of power station218may be configured to fit within indentation216. Thus, a power source connector (e.g., power cable232) may be electrically coupled to a power source on one end (e.g., coupled to port230, which may be in turn coupled to a power line emanating from a power plant), may extend through an aperture of the curb (e.g., aperture210), and may be connected to a power outlet (e.g., power outlets220comprised within power station218) on the other end to charge one or more devices plugged into the power outlet (e.g., smart phone227plugged into outlet224via power cable226).

According to some embodiments, the dimensions of an indentation may be customized. For example, the length, width, and/or height of indentation216may be customized based at least in part on the length, width, and/or height of top plate216. As shown inFIG. 2, the length of indentation216(measured in the direction of the length of curb206) may be approximately equal to one-fourth the length of the top portion213of top plate212; this may advantageously allow for a plurality of indentations (e.g., both indentation216and indentation234) to be comprised within top plate212and spaced apart from each other such that a plurality of power stations (e.g., both power station218and power station236) may be electrically coupled to top plate212. According to some embodiments, the length of indentation216can be at least 4 inches, at least 6 inches, at least 8 inches, at least 10 inches, at least 12 inches, or at least 14 inches.

According to some embodiments, a different power source and/or power source connector may be used to provide power to the different power stations (e.g., power cable232may be connected to port230and may provide power to power station218via indentation216, and a second data cable233(not shown inFIG. 2) may be connected to port231and may provide power to power station236via indentation234). According to some embodiments, the same power source and/or power source connector may be used to provide power to different power stations (e.g., power cable232may be connected to port230and may subsequently be split into two cables, one of which provides power to power station218via indentation216and the other of which provides power to power station236via indentation234).

As shown inFIG. 2, the width of indentation216(measured in the direction of the width of curb206) may be approximately equal to half the width of top plate212; reducing the width of indentation216to be much less than half the width of top plate212may disadvantageously decrease the area by which power station218may couple to top plate212, and increasing the width of indentation216to be much more than half the width of top plate212may disadvantageously reduce the area by which protruding portion214of top plate212connects to top portion213of top plate212. According to some embodiments, the width of indentation216can be at least 2 inches, at least 4 inches, at least 6 inches, at least 8 inches, or at least 10 inches. According to some embodiments, the depth of indentation216(measured in the direction of the height of curb206) may be at least 0.25 inches, at least 0.5 inches, at least 1 inch, at least 1.5 inches, or at least 2 inches; the depth of indentation216may be selected at least to ensure that a portion of power station218can be securely attached to top plate212, but that there can still be room in aperture210underneath indentation216in which to access or store the at least one power source or power source connector within aperture210.

According to some embodiments, an indentation of a top plate can be manufactured via a milling process and/or via one or more stepped-extrusions. Manufacturing an indentation may require specialized tooling. Alternatively, the tooling used to manufacture an indentation may be rapidly reconfigurable, such that a tool may be used to manufacture a wide variety of parts in addition to an indentation of a top plate.

According to some embodiments, a portion of a power station can be removably attached to an indentation of a top plate via a rigid sheet. According to some embodiments, the rigid sheet can be connected to the bottom of the power station (e.g., the side of the power station which is closest to the ground). For example, as shown inFIG. 2, power station218can be coupled to indentation216via rigid sheet222. According to some embodiments, the length, width, and depth of a rigid sheet can be configured to approximately match those of a corresponding indentation of a top plate; as shown inFIG. 2, the length, width, and depth of rigid sheet222approximately match those of indentation216. Thus, a top side of a rigid sheet may be flush to a top side of an indentation, which may beneficially limit damage to the rigid sheet.

According to some embodiments, the rigid sheet may be connected to a side (e.g., a left side or a right side) of the power station which extends in a direction perpendicular to the ground. For example, as shown inFIG. 2, rigid sheet223can be attached to a side of power station218. Connecting the rigid sheet to a side of the power station, rather than to the bottom of the power station, may beneficially allow the coupling of the power station to the top plate to occur in a region of the power station which is closer to the power outlets comprised within the power station.

Removably attaching a power station to an indentation of a top plate via a rigid sheet advantageously can provide increased flexibility: if any dimension of the indentation is modified (e.g., if top plate212is modified), then the corresponding dimension of the rigid sheet may be modified, rather than modifying any dimension of the power station itself.

According to some embodiments, rigid sheet222can be composed of the same material as top portion213of top plate212(e.g., reinforced steel, concrete, aluminum, and/or copper) to provide the same protection to the at least one power source or power source connector comprised within curb segment209as can be provided by top portion213.

According to some embodiments, rigid sheet222can be removably attached to indentation216via at least one fastener. A fastener may include any variation of a removable securing device(s), such as nuts and bolts, screws, pins, nails, any combination thereof, and/or the like. As shown inFIG. 2, rigid sheet222may be removably connected to indentation216via4fasteners, each of which is configured to attach a corner of rigid sheet222to a corner of indentation216.

According to some embodiments, a rigid sheet can comprise a port configured to receive a power source connector (e.g., power cable232). In these embodiments, a power source connector may be electrically coupled to the power source on one end and the power station on the other end. This may advantageously allow power to be transmitted along the shortest path from a power source to power outlets comprised within the power station, thus reducing unnecessary power losses.

According to some embodiments, a portion of each of a plurality of power stations can be removably attached to a respective indentation of a top plate, such that each indentation can be configured to electrically couple a respective power outlet(s) to at least one power source or power source connector comprised within a segment of the curb. According to some embodiments, a portion of each power station is attached to a respective indentation of a top plate via a respective rigid sheet. For example, as shown inFIG. 2, power station218is removably attached to indentation216via rigid sheet222(as explained above) and power station236is removably attached to indentation234via rigid sheet240. Power station218can comprise power outlets220, and power station236can comprise power outlets238. One or more devices on a street or sidewalk (e.g., street202or sidewalk204) may be simultaneously plugged into power outlets220(e.g., a device may be connected to outlet224) and plugged into power outlets236(e.g., a device may be connected to outlet242). As discussed above, a different power source and/or power source connector may be used to provide power to the different power stations, or the same power source and/or power source connector may be used to provide power to the different power stations.

According to some embodiments, the curb may comprise a plurality of top plates; each top plate may be configured to removably attach to and fit within an aperture of the curb, enclosing a top portion of a corresponding segment of the curb when attached. According to some embodiments, each top plate comprises at least one indentation configured to electrically couple a power outlet(s) to a power source or power source connector. For example, as shown inFIG. 2, curb206comprises top plate212, configured to fit within aperture210and enclose a top portion of segment209, and top plate244, configured to fit within aperture248and enclose a top portion of segment210. Moreover, top plate212can comprise indentation216which can be configured to electrically couple outlets220to a power source or power source connector comprised within segment209and indentation234which can be configured to electrically couple outlets238to a power source or power source connector comprised within segment209; similarly, top plate244can comprise indentation252and indentation254, each of which can be configured to electrically couple a respective power outlet (not shown) to a power source or power source connector comprised within segment210.

The same power source or power source connector may be used to power at least one power outlet electrically coupled to different top plates, or a different power source or power source connector may be used to power at least one power outlet depending on the top plate. It may be advantageous to use the same power source or power source connector to power at least one power outlet electrically coupled to different top plates at least to minimize the amount of storage space taken up within the limited storage space afforded by the curb; this may be particularly important for a curb which is configured to provide power to many power outlets. It may be advantageous to use a different power source or power source connector to power at least one power outlet depending on the top plate at least to (1) reduce the distance through which power is transmitted from a power source to a power outlet (and thus to reduce unnecessary power losses); and/or (2) reduce dependency upon any one power source or power source connector.

According to some embodiments, a top plate can include one or more light sources electrically coupled to at least one power source or power source connector stored within a corresponding segment of the curb. For example, top plate212may comprise a light source (e.g., a lightbulb, such as an LED light). A light source comprised within a top plate of a curb may advantageously provide light to pedestrians on a sidewalk and to motor vehicle drivers on a street. According to some embodiments, each top plate comprised within a curb includes at least one light source; according to some embodiments, only one or some of the top plates comprised within a curb includes at least one light source.

A top plate may comprise an aperture in which a portion of a light source can be configured to fit. According to some embodiments, a top plate comprises a plurality of apertures, enabling a plurality of light sources to be attached to the top plate. The aperture(s) may be adjacent to the indentation(s) of the top plate, at least to allow the coupling of the power outlet(s) to the at least one power source or power source connector comprised within the curb, as described above. A light source may be removably attached to the top plate. According to some embodiments, a light source can be removably attached to the top plate via at least one fastener, such as any variation of a removable securing device(s) (e.g., nuts and bolts, screws, pins, nails, any combination thereof, and/or the like). Moreover, a light source may be housed within the top plate, such that a top side of the light source (e.g., the side farthest from the ground) is flush with the top side of the top plate when attached; this may advantageously mitigate any potential damage to the light source.

A light source may be electrically coupled to the same power source and/or power source connector used to power the at least one power outlet, or a light source may be electrically coupled to a different power source and/or power source connector used to power the at least one power outlet. Moreover, each light source may be electrically coupled to the same power source and/or power source connector, or a light source may be electrically coupled to a different power source and/or power source connector compared to another light source.

Although the disclosure has been described with respect to a curb configured to electrically couple at least one power source or power source connector to at least one power outlet, the curb may be configured to electrically and/or communicatively couple other objects. For example, the curb may be configured to electrically and/or communicatively couple at least one data source (e.g., a computer, a database, a web service, an API, any combination thereof, or the like) or data source connector (e.g., a data cable) to at least one data outlet. According to some embodiments, the curb may house the at least one data source or data source connector. For example, some or each of the ports of the curb (e.g., port230and/or port231of curb206) may be configured to receive data from a data source, and the curb may house at least one data cable that is configured to receive and transmit data from the at least one data source.

According to some embodiments, the data cable may be an Ethernet cable that provides an Ethernet connection to at least one data outlet (e.g., an Ethernet port) electrically and/or communicatively coupled to the curb, and subsequently to one or more devices (e.g., a phone and/or a computer) electrically coupled to the at least one data outlet. The Ethernet cable may be housed within the curb, connected to at least one data source on one end, and connected to at least one data outlet on the other end. Thus, the curb may advantageously provide an Ethernet connection to one or more devices connected thereto. The Ethernet connection may be advantageous at least to provide a faster, more reliable, and/or more secure internet connection to the one or more devices than would otherwise be achievable (e.g., via WiFi).
