Abstract

An apparatus for providing data communication and power to a device located in a room having a power outlet is disclosed. The power outlet may be a standard AC outlet, for example. The apparatus includes a cable extending from the device and having a plug comprising a plug body. Prongs extend from the plug body and couple to the power outlet to receive power. A first near field communication antenna is carried by the plug body. A communication module has a second near field communication antenna and is located in the room in proximity to the plug. At least one of the first near field communication antenna and the second near field communication antenna communicates data wirelessly to the other of the first near field communication antenna and the second near field communication antenna.

Claims

1. An apparatus for providing data communication and power to a device located in a room, the room having a power outlet, the apparatus comprising

a cable extending from the device and having at one end thereof a plug comprising a plug body, a plurality of prongs extending from the plug body and configured to couple to the power outlet to receive power,

a first near field communication antenna carried by the plug body,

near field communication circuitry carried by the device and coupled to the first near field communication antenna via at least one conductor routed along the cable, wherein the plug body is devoid of any circuit components of the near field communication circuitry, and

a communication module comprising a second near field communication antenna, the communication module being located in the room in proximity to the plug, at least one of the first near field communication antenna and the second near field communication antenna communicating data wirelessly to the other of the first near field communication antenna and the second near field communication antenna, wherein the first near field communication antenna is included in a label that sticks to the plug body, wherein the label is devoid of any electrical components other than the antenna and at least one conductor leading to the antenna.

2. The apparatus of claim 1, wherein the first near field communication antenna and the second near field communication antenna are spaced apart by about four centimeters (4 cm) or less when the first near field communication antenna and the second near field communication antenna communicate wirelessly.

3. The apparatus of claim 1, wherein the first near field communication antenna serves as a passive target and the second near field communication antenna is included as part of an initiator circuit that actively generates a radio frequency field via the second near field communication antenna to power up the passive target for data transfer.

4. The apparatus of claim 1, wherein the second near field communication antenna serves as a passive target and the first near field communication antenna included as part of an initiator circuit that actively generates a radio frequency field via the first near field communication antenna to power up the passive target for data transfer.

5. The apparatus of claim 1, further comprising a wall plate carrying the second near field communication antenna and the wall plate having an opening through which the power outlet is accessible.

6. The apparatus of claim 1, further comprising a wall plate carrying the second near field communication antenna and the wall plate being configured to cover an existing wall plate associated with the power outlet.

7. The apparatus of claim 1, further comprising first circuitry coupled to the first near field communication antenna and second circuitry coupled to the second near field communication antenna, the first and second circuitry communicating via the first near field communication antenna and the second near field communication antenna according to a peer-to-peer protocol.

8. The apparatus of claim 1, further comprising a read/write module coupled to the first near field communication antenna.

9. The apparatus of claim 1, further comprising a read/write module coupled to the second near field communication antenna.

10. An apparatus for coupling a patient-support device to a power outlet and to a computer network in a healthcare facility, the apparatus comprising

a cable extending from the patient-support device and having at one end thereof a plug comprising a plug body, a plurality of prongs extending from the plug body and configured to couple to the power outlet to receive power, and a first near field communication antenna carried by the plug body,

near field communication circuitry carried by the patient-support device and coupled to the first near field communication antenna via at least one conductor routed along the cable, wherein the plug body is devoid of any circuit components of the near field communication circuitry,

a communication module comprising a second near field communication antenna, at least one of the first near field communication antenna and the second near field communication antenna communicating data wirelessly to the other of the first near field communication antenna and the second near field communication antenna, wherein the first near field communication antenna is included in a label that sticks to the plug body, wherein the label is devoid of any electrical components other than the antenna and at least one conductor leading to the antenna.

11. The apparatus of claim 10, wherein the communication module comprises a housing in close proximity to the power outlet and the second near field communication antenna is situated in the housing.

12. The apparatus of claim 11, wherein the housing has an opening through which the plug is inserted to couple to the power outlet.

13. The apparatus of claim 11, wherein the communication module further comprises a mounting plate that mounts over a cover plate associated with the power outlet and the housing couples to the mounting plate.

14. The apparatus of claim 10, wherein the communication module comprises a Nurse Call cancel button.
