Abstract

An apparatus for electrically and mechanically coupling a connection portion of a sensor assembly with a connection portion of an interface cable is provided. The apparatus includes a frame having an EMI shielding material. The frame defines a first port operable to engage the connection portion of the sensor assembly and a second port operable to engage the connection portion of the interface cable. The frame includes attachment features operable to mechanically secure the connection portion of the sensor assembly and the connection portion of the interface cable relative to the frame. The frame is configured to provide a Faraday Cage around substantially all of the connection portion of the sensor assembly and the connection portion of the interface cable when the connection portions are in coupled configuration.

Claims

1. An apparatus for electrically and mechanically coupling a connection portion of a sensor assembly with a connection portion of an interface cable, comprising:

a frame having an EMI shielding material, which frame defines a first port operable to engage the connection portion of the sensor assembly and a second port operable to engage the connection portion of the interface cable;

wherein the frame includes attachment features operable to mechanically secure the connection portion of the sensor assembly and the connection portion of the interface cable relative to the frame; and

wherein the frame is configured to provide a Faraday Cage around substantially all of the connection portion of the sensor assembly and the connection portion of the interface cable when the connection portions are in coupled configuration; and

wherein the connection portion of one of the interface cable and the sensor assembly includes a printed circuit board, and the other of the interface cable and the sensor assembly includes a DisplayPort connector.

2. The apparatus of claim 1, wherein the apparatus further comprises a housing configured to enclose the frame, which housing is formed of an electrically non-conductive material.

3. The apparatus of claim 1, wherein the frame is configured to form an internal cavity surrounded by one or more walls, and a first end of the cavity defines the first port and is configured to receive the connection portion of the sensor assembly, and an opposing second end of the cavity defines the second port and is configured to receive the connection portion of the interface cable.

4. The apparatus of claim 3, wherein the cavity is configured such that the frame walls surround substantially all of the connection portion of the sensor assembly and the connection portion of the interface cable when the connection portions are in coupled configuration.

5. The apparatus of claim 4, wherein the walls include the attachment features operable to mechanically secure the connection portion of the sensor assembly and the connection portion of the interface cable relative to the frame.

6. The apparatus of claim 5, wherein the attachment features are positioned to maintain a mechanical and electrical connection between the connection portions.

7. The apparatus of claim 6, wherein the attachment features are positioned to bias the connection portions together.

8. The apparatus of claim 6, wherein the attachment features are configured such that a predetermined amount of force is required to separate one or both of the connection portions from the frame.

9. The apparatus of claim 8, wherein the predetermined amount of force is equal to or less than an amount of force required to remove the sensor assembly adhered to a subject.

10. The apparatus of claim 6, wherein the cavity is configured such that the frame walls surround substantially all of the printed circuit board and the DisplayPort connector when they are in coupled configuration.

11. An apparatus for sensing a biological characteristic of a subject, comprising:

a sensor assembly operable to be attached to the subject, which sensor assembly is operable to produce electrical signals indicative of the biological characteristic being sensed, and which sensor assembly includes a connection portion;

a base unit having a processor, which base unit is operable to receive the electrical signals from the sensor assembly through an interface cable, and which interface cable includes a connection portion; and

a coupler that includes a frame having an EMI shielding material, which frame defines a first port operable to engage the connection portion of the sensor assembly and a second port operable to engage the connection portion of the interface cable, wherein the frame includes attachment features operable to mechanically secure the connection portion of the sensor assembly and the connection portion of the interface cable relative to the frame, and wherein the frame is configured to provide a Faraday Cage around substantially all of the connection portion of the sensor assembly and the connection portion of the interface cable when the connection portions are in coupled configuration.

12. The apparatus of claim 11, wherein the coupler further comprises a housing configured to enclose the frame, which housing is formed of an electrically non-conductive material.

13. The apparatus of claim 11, wherein the frame is configured to form an internal cavity surrounded by one or more walls, and a first end of the cavity defines the first port and is configured to receive the connection portion of the sensor assembly, and an opposing second end of the cavity defines the second port and is configured to receive the connection portion of the interface cable.

14. The apparatus of claim 13, wherein the cavity is configured such that the frame walls surround substantially all of the connection portion of the sensor assembly and the connection portion of the interface cable when the connection portions are in coupled configuration.

15. The apparatus of claim 14, wherein the walls include the attachment features operable to mechanically secure the connection portion of the sensor assembly and the connection portion of the interface cable relative to the frame.

16. The apparatus of claim 15, wherein the attachment features are positioned to maintain a mechanical and electrical connection between the connection portions.

17. The apparatus of claim 16, wherein attachment features are positioned to bias the connection portions together.

18. The apparatus of claim 16, wherein the attachment features are configured such that a predetermined amount of force is required to separate one or both of the connection portions from the frame.

19. The apparatus of claim 18, wherein the predetermined amount of force is equal to or less than an amount of force required to remove the sensor assembly adhered to a subject.

20. The apparatus of claim 16, wherein the connection portion of one of the interface cable and the sensor assembly includes a printed circuit board, and the other of the interface cable and the sensor assembly includes a DisplayPort connector, and the cavity is configured such that the frame walls surround substantially all of the printed circuit board and the DisplayPort connector when they are in coupled configuration.
