FIG. 1 is a perspective view of a door system 10 is accordance with the present disclosure. The door system 10 may be mounted in a space 11 to be enclosed such as a garage, warehouse or any other domestic or commercial building. The door system 10 operates the opening and closing of a door 12 such as an upward acting door 12 as shown in FIG. 1. The space 11 may in defined, at least in part, by the door 12, walls 14, ceiling 16 and floor 18.

Tracks 20 may be mounted to the walls 14 and/or ceiling 16 to support and guide the door 12 equipped with rollers (not shown) which roll along the tracks 20. An operator 22 is operatively connected to the door 12 to move the door 12 along the tracks 20 between open and closed positions. The operative connection may include a rail 24 connecting the operator 22 and the 12 and allow a trolley (not shown) to move along the rail 24 when the door 12 is in operation.

A power supply 26 such as a connection to an AC outlet for providing line power powers the operator 22. In some embodiments, the power supply may include a battery to provide DC power to the operator 22. In particular, batteries may provide back-up power. In such embodiments, the battery located in the power supply 26 may have a cord 27 connecting the power supply 26 to an AC outlet in order for AC power charge the battery suppling DC power to the operator. Some embodiments may include power converters to allow power to be converted between AC and DC power to provide whatever power is needed to operate the motors associated with the operator 22.

The door system 10 includes accessory devices. Some door systems use batteries or line voltage connections at the accessory devices to provide power to the accessory devices that are remotely located from the operator 22. While this method may be effective, it also has certain drawbacks such as limited battery life and aesthetic and logistical issues associated with power supply cords connecting the accessory devices to a power source.

In the present disclosure, a laser will provide power to the accessory device(s). A laser transmitter or eTransmitter 28 is connected to a power supply such as line AC power. In some embodiments, a battery (such as, for example a back-up battery) may provide DC power to the laser transmitter 28. In some embodiments, the laser transmitter 28 may be integrated or otherwise associated with the operator 22. In other embodiments the laser transmitter 28 may be remotely located from the operator 22 and may be operatively connected to the operator 22.

The door system 10, may include accessories and each accessory has a laser receiver. FIG. 1 shows a laser receiver 30 for a wall console 32. The wall console 32 is configured for sending control commands to the operator 22. Also shown are a laser receiver 34 for an edge sensor 36, a laser receiver 38 for a photo sensor 40. A laser reflector 42 is also shown. The door 12 is equipped with smart glass 44 a laser receiver 46 for the smart glass 46.

The wall console 32 is a common accessory device. It is usually wall mounted and allows a user to give control signals to the operator 22 via transmitters/receivers/transceivers 50 operatively connected to the wall console 32 and operator 22.

Other optional accessories may include Smart Glass windows 44. The Smart Glass windows 44 may be configured to be adjustable between transparent, various levels of translucent, and even opaque depending upon a current or voltage applied to the Smart Windows 44. The Smart Glass may communicate with the operator 22 via a transmitter/receiver/transceiver 50.

Sensors such as a reflective sensor 40 and edge sensor 36 may use the laser generated by the laser transmitter 28 to run along the bottom of the door 12 as an edge sensor 36 to detect obstacles. If an obstacle is detected, the laser beam will be broken and the photo sensor 40 will transmit the information to the operator 28 with the transmitter/receiver/transceiver 50.

The laser transmitter 28 emits a laser to a laser receivers 30, 34, 38, and 44, to power their related accessories 32, 36, 40, and 44. The laser receivers 30, 34, 38, and 44 convert the energy from the laser to power to supply the accessories 32, 36, 40, and 44.

In some embodiments, the laser transmitter 28 emits a different laser in a different direction depending upon what accessory is desired (or needs to be) powered.

Lights located remotely from the operator 28 and other accessories may also be powered by the laser as described herein.

In the event that emitting the laser from the laser emitter 28 to the laser receivers 30, 34, 38, and 44 in a direct line-of-sight is not practical, laser reflectors 42 may be used to reflect the laser beam 52 as shown in FIGS. 2 and 3.

FIG. 2 shows an embodiment were a single laser reflector 42 is used to direct the laser beam 52 from the laser emitter 28 to the laser receiver 30, 34, 38, or 46. The laser reflector 42 may be attached with attaching structure 48 to the walls 14, ceiling 16 or any other suitable mounting surface. The laser beam 52 approaches the reflector 42 at an approach angle z and an exit angle y. The angle A is defined by the approaching and exiting laser beam 52. Angles A, z and y are selected to direct the laser beam 52 to where it is desired to go to reach the laser receiver 30, 34, 38, or 46.

FIG. 3 shows an embodiment where the laser beam 52 is reflected several times on various laser reflectors 42 on its way to the laser receiver 30, 34, 38, 46. Multiple reflectors 42 are connected to walls 14 or the ceiling 16. The approach angles z, x, v, t; the exit angles y, w, u, s; and the angles between the approach and exit beams 52 A, B, C, and D are selected to allow the laser beam 51 to be reflected to where it is desired to go. As many or as few laser reflectors 42 may be used to direct the laser beam 52 in a desired manner.

FIGS. 4 and 5 show a laser receiver 46 that is mounted to a garage door 12. In FIG. 4, the door 12 is in a horizontal orientation such as when an upward acting door 12 is in an open position. In FIG. 5, the door 12 is in a vertical orientation such as when an upward acting door 12 is in a closed position. Mounting a laser receiver 46 on a garage door 12 provides challenges in that the door 12 moves, causing the laser receiver 46 to move and change orientation. When the laser receiver 46 moves, it makes it difficult for the eTransmitter 28 to provide power efficiently to the laser receiver 46.

In order to mitigate movement and/or orientation of laser receiver 46 with respect laser emitter 28, the laser receiver 46 may be mounted with a hinged (or other movable type) mount 52 to the garage door 12. The hinge mount 52 may allow the laser receiver 46 to move as the door 12 moves to maintain an advantageous orientation with respect to the laser transmitter 28.

The hinge mount 52 may include a door mount 54 attached to the door 12 and a laser receiver mount 56 attached to the laser receiver 46. The door mount 54 and the laser receiver mount 56 may be attached to each other with a hinge pin 58 or other movable connection that allows laser receiver 46 to maintain an orientation that allows the laser receiver 46 to receive power from the laser transmitter 28. To facilitate movement to maintain a desired orientation of the laser receiver 46 when the door 12 moves, a weight 60 may be attached to the laser receiver 46 maintain the laser receiver 46 is a vertical position.

While the disclosure has been described in terms of exemplary aspects, those skilled in the art will recognize that the disclosure can be practiced with modifications in the spirit and scope of the appended claims. These examples given above are merely illustrative and are not meant to be an exhaustive list of all possible designs, aspects, applications or modifications of the disclosure.
