Abstract

An apparatus interposed between a healthcare pillow speaker and an internally-unmodified commodity television where said apparatus powers the pillow speaker, enables the pillow speaker to control the television and drives the pillow speaker with said television audio content. The apparatus is designed to attain applicable healthcare safety approvals. The apparatus is designed to be compatible with standard healthcare equipment and to be placed within new and existing installations. The apparatus can selectively shut off the audio drivers to reduce noise. The apparatus generates its own audio content for the pillow speaker. The apparatus can enable, disable, set access timers, track and report on user access and equipment operational. The apparatus can internally configure limits and alternatives in how the television equipment will be controlled.

Claims

1. A hospital grade entertainment interface device comprising:

an interface unit;

a plurality of communications ports communicatively connected to said interface unit,

wherein one or more of said plurality of communications ports is a media communications port,

wherein one or more of said plurality of communications ports is a control communications port,

wherein one of said plurality of communications ports is a pillow speaker communications port,

wherein said interface unit is capable of processing commands received from one or more of said plurality of communications ports,

wherein said interface unit is capable of communicating media information via said one or more of said plurality of communications ports,

wherein said interface unit is capable of communicating control information via said one or more of said plurality of communications ports,

wherein said interface unit is capable of communicating media information via said pillow speaker communications port,

wherein said interface unit galvanically isolates one or more devices connected to said interface unit from a pillow speaker connected to said pillow speaker communications port by providing an interface unit divided into two distinct electrical sections, an upper and lower section, wherein said upper and lower sections have no direct electrical connections and possess power and ground separate from each other, wherein said upper and lower sections are bridged only by a plurality of galvanic isolation components which provide galvanic isolation of power and signals, thereby providing isolated power to said lower section in which said pillow speaker communication port resides, and permitting operational interactions between said one or more devices and said pillow speaker, said one or more devices being connected to said upper section; and

a power supply communicatively connected to said interface unit,

wherein said power supply and said plurality of communications ports are galvanically isolated from said pillow speaker communications port.

2. The system of claim 1 wherein the power supply is provided by a medical grade power supply.

3. The system of claim 1 wherein said pillow speaker communications port is galvanically isolated from said plurality of communications ports.

4. The system of claim 1 wherein said media information may be comprised of one or more of audio information, data information and video information.

5. The system of claim 1 wherein said interface unit is capable of transmitting media content to said pillow speaker from one or more connected peripheral devices.

6. The system of claim 1 wherein the interface unit is further comprised of circuitry for enhancing fidelity and dynamic range of audio output to the pillow speaker communications port.

7. The system of claim 1, wherein said one or more galvanically isolated components comprise a power isolation component.

8. The system of claim 7, wherein said one or more galvanically isolated components comprise audio isolation components.

9. The system of claim 8, wherein said one or more galvanically isolated components comprise amp control isolation components.

10. The system of claim 9, wherein said one or more galvanically isolated components comprise data isolation components.

11. The system of claim 1, wherein one of said one or more devices is a television.

12. The system of claim 1, wherein said interface unit enables a pillow speaker to operate a television without use of a commercial grade control interface or set top box.

13. A method of controlling an entertainment system, by way of a hospital grade entertainment interface device, the method comprising the steps of:

receiving, at an interface unit, a command from a pillow speaker communications port;

processing said command at said interface unit into a control communication;

transmitting said control communication via a communications port;

processing media information received from a media communications port at said interface unit;

transmitting media data via said pillow speaker communications port; and

electrically isolating one or more devices or a power source connected to said interface unit from a pillow speaker connected to said pillow speaker communications port by providing an interface unit divided into two distinct electrical sections, an upper and lower section, wherein said upper and lower sections have no direct electrical connections and possess power and ground separate from each other, wherein said upper and lower sections are bridged only by a plurality of galvanic isolation components which provide galvanic isolation of power and signals, thereby providing isolated power to said lower section in which said pillow speaker communication port resides, and permitting operational interactions between said one or more devices and said pillow speaker, said one or more devices being connected to said upper section.

14. The method of claim 13 further comprising the step of:

removing electrical noise from an audio signal path in said interface unit.

15. The method of claim 13 further comprising the step of:

maintaining dynamic range and frequency response of said media information without introducing harmonic electrical noise.

16. The method of claim 13 further comprising the step of:

communicating isolated electrical power via said pillow speaker communications port.

17. The method of claim 13 further comprising the steps of:

receiving a rental access code via a communications port;

processing said rental access code at said interface unit;

setting said interface unit into a state based on said processing of said rental access code, wherein said state enables control and viewing access of a television by a pillow speaker for a set duration of time if said rental code is valid; and

sending a control signal via said control communications port.

18. The method of claim 17 further comprising the step of:

determining, at said interface unit, whether said rental access code is valid.

19. The method of claim 13, wherein said interface device galvanically isolates a consumer television from a hospital grade pillow speaker.

20. The method of claim 13 further comprising the steps of:

receiving, at said interface unit, a rental access code from a galvanically isolated pillow speaker communications port;

processing said rental access code at said interface unit into a control communication;

determining, at said interface unit, whether said processed rental access code is valid; and

setting said interface unit into a state based on said processing of said rental access code, wherein said state enables control and viewing access of a television by a pillow speaker for a set duration of time if said rental access code is valid.

21. The method of claim 20 further comprising the steps of:

receiving, at said interface unit, a command from said pillow speaker communications port; and

determining, at said interface unit, whether said command is permissible.

22. The method of claim 21 further comprising the steps of:

transmitting, from said interface unit, a control communication via a communications port when said command is determined to be permissible;

processing media information received from a media communications port at said interface unit; and

transmitting media data via said pillow speaker communications port.

23. The method of claim 13 further comprising the step of:

galvanically isolating said pillow speaker communications port.

24. The method of claim 13 further comprising the step of:

removing electrical noise from a media information signal path in said interface unit.

25. The method of claim 13 further comprising the step of:

maintaining, at said interface unit, dynamic range and frequency response of said media information without introducing harmonic electrical noise.
