BACKGROUND OF THE INVENTION 
       [0001]    The subject matter herein relates generally to wireless power systems for a closure member in a closable opening. 
         [0002]    Closable openings have closure members associated therewith that open and close the closable opening. For example, a door may be received in a doorway, which opens and closes the opening to the building or structure. Other examples may include a window received in a window opening, which opens and closes the opening to the building or structure. 
         [0003]    Some applications have a need for powering electrical components associated with the closure member. For example, some applications have an electronic lock for locking and unlocking the closure member. An electronic keypad is provided that unlocks the electronic lock. The electronic lock may or may not include a radio system for communicating with a home automation system or other controlling device. The electronic lock requires power to actuate the electronic lock. Typically, a battery is provided in the electronic lock assembly. The battery needs to be replaced often, which may be tedious. The housing of the electronic lock must be large enough to hold the battery. To avoid the use of a battery, and thus eliminate the need for replacing batteries, some applications have been proposed that hard wire the electronic lock to building power. For example, a power wire spans from the door frame to the door at the hinged side of the door. The wire is routed through the door to the latching and locking side of the door. It is difficult and expensive to route wires to provide power to the lock assembly. 
         [0004]    A need remains for a wireless system for a closure member in a closable opening that may transfer power and/or data to a closure member. 
       BRIEF DESCRIPTION OF THE INVENTION 
       [0005]    In one embodiment, a wireless door lock power system is provided including a power transmitter configured to be coupled to a building power supply having a transmit face at or near a door jamb and a power receiver configured to be coupled to a door closably received in the door jamb. The power receiver has a receive face at or near an edge of the door. The power receiver receives a wireless power transmission from the power transmitter. A chargeable battery is received in the door. The battery is electrically coupled to the power receiver. The battery receives power from the power receiver to recharge and maintain the charge of the battery. An electronic door lock is operably coupled to the battery. The electronic door lock has a lock electronically actuated to lock the door to the doorjamb. 
         [0006]    In a further embodiment, a closure member wireless power system for a closable opening is provided including a power transmitter configured to be coupled to a power supply. The power transmitter has a transmit face at or near an edge of a frame of the closable opening. The wireless power system also includes a power receiver configured to be coupled to a closure member closably received in the frame of the closable opening. The power receiver has a receive face at or near an edge of the closure member. The power receiver receives a wireless power transmission from the power transmitter. The wireless power system includes a powered electrical component mounted to or housed in the closure member. The powered electrical component is electrically connected to and powered by the power receiver and/or the battery it is connectect to.

The powered electrical component  410  may be a display screen on the window  402 . The powered electrical component  410  may be a camera in other various embodiments which may be powered by the wireless power system  400 . The powered electrical component  410  may be a wireless data transmitter or a wireless data receiver in various embodiments or in combination with other electrical or electronic components. For example, the powered electrical component  110  may be a wireless radio for communication with a home automation system or other remote control device. 
         [0046]    It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments (and/or aspects thereof) may be used in combination with each other. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from its scope. Dimensions, types of materials, orientations of the various components, and the number and positions of the various components described herein are intended to define parameters of certain embodiments, and are by no means limiting and are merely exemplary embodiments. Many other embodiments and modifications within the spirit and scope of the claims will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. Further, the limitations of the following claims are not written in means-plus-function format and are not intended to be interpreted based on 35 U.S.C. §112(f), unless and until such claim limitations expressly use the phrase “means for” followed by a statement of function void of further structure.

Summary:
A wireless door lock power system includes a power transmitter configured to be coupled to a building power supply having a transmit face at or near a door jamb and a power receiver configured to be coupled to a door closably received in the doorjamb. The power receiver has a receive face at or near an edge of the door. The power receiver receives a wireless power transmission from the power transmitter. A chargeable battery is received in the door. The battery is electrically coupled to the power receiver. The battery receives power from the power receiver to recharge the battery. An electronic door lock is operably coupled to the battery. The electronic door lock has a lock electronically actuated to lock the door to the doorjamb.
