Additionally, there is a problem with providing power to many devices while creating a dynamic or flexible system that allows for device relocation, addition of devices, and removal of devices for the power/signal systems. Existing solutions provide cable raceways with multiple connection points (outlet strip approach) or power track systems (track lighting approach). Although many conductors for power and signal combinations can be used, the "outlet strip approach" lacks flexibility and expandability for adding or relocating devices. Traditional powered track systems lack easy ways to incorporate many power and signal conductors. Additionally for each conductor added to the traditional power track systems the connector required to access those conductors grows significantly in complexity and size.

[27] As illustrated in one embodiment in Figures 1 through 3, an exemplary low power voltage system 200 is shown. In this example, the low voltage power system 200 is an exemplary lighting system. Those of skill in the art will recognize that any low voltage power system may be utilized without departing from these embodiments. The exemplary lighting system 200 may also be a track and connector assembly 200 for use with a retail merchandise display system. The track and connector assembly 200 may include a track 210 and a power connector assembly 250. Figure 1 illustrates a perspective view of the track and connector assembly 200.

Additionally, those of skill in the art will recognize that any material, shape, form, or type of ferrous material may be utilized for the metal plates 226, such as brass. The track 210 may also include a track mounting bracket 222. The track mounting bracket 222 may be utilized to mount to the merchandise display system, thereby allowing the track and connector assembly 200 to attach to the merchandise display system at any preferred location. Those of skill in the art will recognize that the merchandise display system may include multiple tracks 210 and multiple power connector assemblies 250 without departing from this invention.

[29] The power connector 250 may include a housing which may include a first or left housing 252 and a second or right housing 254.

The low voltage power device may include various lighting systems, such as individual LEDs or other such similar low voltage power assemblies for the merchandise display system.

[30] Additionally, the power connector 250 may include a magnetic source 260 or mating device. The magnetic source may be a magnetic coil, magnet, or induction coil. Other magnetic or mating devices may be utilized without departing from this invention. The magnetic source 260 may be configured and located in line with the metal plate 226 on the track 210. The magnetic source 260 allows the power connector 250 and any low voltage power supply assemblies connected to the power connector 250 the ability to be moved along the entire length of the track 210. For example, individual LEDs may utilized and moved along the entire length of the track 210.

[31] As illustrated in another embodiment in Figures 4 through 7, another exemplary low voltage power supply system 300 is shown. In this embodiment, a lighting system 300 is utilized as the low voltage power supply system, however other low voltage power supply systems may be utilized without departing from these embodiments. For example, the exemplary lighting system 300 may also be a track and connector assembly 300 for use with a retail merchandise display system.

[32] The track and connector assembly 300 may include a track 310 and a power connector 350. Figure 4 illustrates a perspective view of the track and connector assembly 300. Figure 5 illustrates a cross-section view of the track and connector assembly 300 to include both the track 310 and the power connector assembly 350. Figure 6 illustrates a perspective view of the track 310. Figure 7 illustrates a perspective view of the power connector assembly 350. Generally, the power connector assembly 350 connects to the track 310 both through a magnetic connection and a power connection. The power connector assembly 350 may connect to the track 310 along any portion of the track 310.

[33] The track 310 may include one or more conductive plates 324 and one or more ferrous plates 326. As illustrated in Figure 12, a plurality of insulative materials 328 may be located between each of the ferrous plates 326 and the conductive plates 324. Those of skill in the art will recognize that any material, shape, form, or type of ferrous material may be utilized for the ferrous plates 324. Additionally, those of skill in the art will recognize that any material, shape, form, or type of conductive material may be utilized for the conductive plates 326, such as brass. The track 310 may also include a track mounting bracket (not shown in this embodiment). The track mounting bracket may mount to the merchandise display system, thereby allowing the track and connector assembly 300 to attach to the merchandise display system at any preferred location. In another aspect, the track may be a freestanding track without the need for a track mounting bracket. Those of skill in the art will recognize that a merchandise display system may include multiple tracks 310 and multiple power connector assemblies 350 and low voltage power supply systems without departing from this invention.

[34] As illustrated in Figures 4, 5, and 6, the power connector 350 may include a printed circuit board 352 which houses the electronics for the power connector 350. In this given embodiment, a lighting assembly 354 that includes one or more LEDs 355 and/or other light sources known and used in the art may be electronically connected to the printed circuit board 352. Other low voltage power supply devices may be utilized and electronically connected to the printed circuit board 352 without departing from this invention. Additionally, the power connector 350 may include one or more power connector contacts 356. The power connector contacts 356 may be configured and located in line with the conductive plates 324 on the track 310. The power connector contacts 356 may be defined by spring contacts or any other type of power contacts known and used in the art. The power contacts 356 may then provide power to the lighting assembly 354, such as individual LEDs or other such similar lighting assemblies for the merchandise display system.

[35] Additionally, the power connector 350 may include a magnetic source 260 or mating device. The magnetic source may be a magnetic coil, magnet, or induction coil. Other magnetic or mating devices may be utilized without departing from this invention. The magnetic source 360 may be configured and located in line with the ferrous plates 326 on the track 310. The magnetic source 360 allows the power connector 350 and any lighting assemblies 354 (or low voltage power connectors) to be connected to the power connector 350 with the ability to be moved along the entire length of the track 310. [36] These embodiments illustrated in Figures 1 through 7 solve the problem with providing power to many devices while trying to create good wire management, and also creating a dynamic or flexible system that allows for device re-location, addition of devices, and removal of devices for the power/signal system. Existing solutions include cable raceways with multiple connection points (outlet strip approach) or powered track systems (track lighting approach). However these traditional approaches fall short in several ways. Although many conductors for power and signal combinations can be used, the "outlet strip approach" lacks flexibility and expandability for adding or relocating devices. Traditional powered track systems lack easy ways to incorporate many power and signal conductors. Additionally for each conductor added to the traditional power track systems the connector required to access those conductors grows significantly in complexity and size.

[37] The purpose of these embodiments illustrated in Figures 1 through 7 is to provide a "break away" connection. Another purpose of these embodiments illustrated in Figures 1 through 7 is to provide an easy to use power and signal distribution track system. Track lighting is a good example of a powered track system intended for distributing power to many devices, however current track lighting systems do not use magnetic attachment methods and are not intended for distributing more than power for connected devices. These embodiments are intended to distribute both power while allowing the easy movement and placement of connected devices such as lighting systems for the retail merchandise display systems.

[38] Examples of retail uses for this embodiment are under-shelf or display-case lighting that may require spot lights for product specials. Spot light modules such as the proof of concept prototype could be used to add lighting in a dynamic, modular, and reconfigurable way. Examples of non-retail applications might include systems which use sensor modules that communicate via additional conductors in the configuration or assembly. This type of application would allow for easy customization of the sensor system.

[39] If additional voltages are added to the configuration of products, additional configurations of products that require different voltages could be connected on the same distribution track such that the devices contacts make contact only with the conductors required. In a given aspect of this invention, there may two bus bars and/or conductive plates. In another aspect of this invention, there may be four bus bars and/or conductive plates in order to handle various additional voltages.

[40] Other devices using this distribution track may separate the magnetic connector from the device itself by using a corded magnetic connector. This allows for many types of devices (especially larger devices) to make use of the distribution track. One example might be embedded hardware devices which use the distribution track as a means for getting power and for intercommunications between embedded devices utilizing additional signal conductors.

[41] Another advantage of this embodiment is that the distribution track implementations may incorporate many conductors for power and/or signal and may only grow in size as conductors are added. The additional conductors for power and/or signal may not increase the complexity because the access of one conductor does not interfere with the other conductors as it does in the traditional powered track approach. This characteristic allows the design technique to be scalable for many applications.

[42] LED lighting systems may be utilized with these embodiments as a low voltage power supply with magnetic connections, and specifically LED lighting systems utilized with a retail merchandise display system. LED lighting systems as disclosed in U.S. Application Serial No. 13/162,076, filed June 16, 2011 and U.S. Application Serial No. 12/955,198, filed November 29, 2010 wherein each of the above-identified U.S. applications are herein incorporated by reference in their entirety.
