Abstract

A data acquisition system includes a receptacle and a data acquisition device. The receptacle has a housing, sensor inputs to receive data signals from sensors coupled to an object, and a rib to block insertion of a standard Universal Serial Bus (USB) plug and facilitate insertion of a modified USB plug having a slot that mates with the rib. The data acquisition device includes circuitry to receive, store and process data, a USB plug having pins operatively coupled to the circuitry, a first subset of pins configured to receive data signals from the receptacle and a second subset of pins configured to support standard USB communication with USB-compliant devices, and a slot formed in the USB plug such that the slot facilitates interconnection of the USB plug both with standard USB-compliant devices and with the receptacle, the slot mating with the rib to facilitate interconnection.

Claims

1. A data acquisition device comprising:

circuitry configured to receive biometric data acquired from one or more sensors having electrode leads coupled to a living subject;

a Universal Serial Bus (USB) plug having a plurality of pins operatively coupled to the circuitry, a first subset of the plurality of pins configured to receive data signals from the one or more sensors having electrode leads coupled to the living subject and a second subset of the plurality of pins configured to support standard USB communication with USB-compliant devices; and

a modification to the USB plug configured such that the modification facilitates interconnection of the USB plug both with standard USB-compliant devices and with a living subject-connected receptacle that is configured to prevent interconnection with standard USB plugs;

wherein the modification to the USB plug comprises an opening that mates with an accommodating protrusion in the living subject-connected receptacle.

2. The device of claim 1 in which the USB plug comprises a USB 3.0 Type-A connector.

3. The device of claim 2 in which the first subset of the plurality of pins comprises pins 5-9 of the USB 3.0 Type-A connector and the second subset of the plurality of pins comprises pins 1-4 of the USB 3.0 Type-A connector.

4. The device of claim 1 in which the opening formed in the USB plug comprises a slot that mates with an accommodating protrusion in the living subject-connected receptacle.

5. The device of claim 4 in which the USB plug has top and bottom sides, and the slot is formed symmetrically in at least one of the USB plug'"'"'s top and bottom sides.

6. The device of claim 1 further comprising circuitry to store, process and/or transmit the acquired data.

7. A data acquisition receptacle comprising:

a plurality of sensor inputs configured to receive biometric data signals from one or more sensors having electrode leads coupled to a living subject; and

a connection prevention mechanism that is configured to prevent insertion of a standard Universal Serial Bus (USB) plug and to facilitate insertion of and electrical connection with a modified USB plug having a feature that defeats the connection prevention mechanism;

wherein the connection prevention mechanism comprises a protrusion that mates with an accommodating opening in the modified USB plug.

8. The receptacle of claim 7 in which the protrusion comprises a rib.

9. The receptacle of claim 8 in which the rib is formed along a center portion of the receptacle.

10. The receptacle of claim 8 further comprising a substrate configured to facilitate secure connection of the modified USB plug while inserted in the receptacle.

11. The receptacle of claim 7 further comprising a recess to receive the modified USB plug.

12. The receptacle of claim 7 in which the receptacle is formed in an unshrouded configuration that lacks a recess.

13. A data acquisition system comprising:

(i) a receptacle including;

(a) a housing;

(b) a plurality of sensor inputs configured to receive biometric data signals from one or more sensors having electrode leads coupled to a living subject; and

(c) a rib that is configured to block insertion of a standard Universal Serial Bus (USB) plug and to facilitate insertion of and electrical connection with a modified USB plug having a slot that mates with the rib when inserted; and

(ii) a data acquisition device including;

(a) circuitry configured to receive, store and/or process data received via the receptacle from the one or more sensors having electrode leads coupled to the living subject;

(b) a USB plug having a plurality of pins operatively coupled to the circuitry, a first subset of the plurality of pins configured to receive data signals from the receptacle and a second subset of the plurality of pins configured to support standard USB communication with USB-compliant devices; and

(c) a slot formed in the USB plug such that the slot facilitates interconnection of the USB plug both with standard USB-compliant devices and with the receptacle, the slot mating with the rib to facilitate interconnection between the data acquisition device and the receptacle.

14. The system of claim 13 in which the USB plug comprises a USB 3.0 Type-A connector.

15. The system of claim 14 in which the first subset of the plurality of pins comprises pins 5-9 of the USB 3.0 Type-A connector and the second subset of the plurality of pins comprises pins 1-4 of the USB 3.0 Type-A connector.

16. The system of claim 13 in which the USB plug has top and bottom sides, and the slot is formed symmetrically in at least one of the USB plug'"'"'s top and bottom sides.

17. The system of claim 13 in which the receptacle'"'"'s rib is formed along a center portion of the receptacle.

18. The system of claim 13 in which the receptacle further comprises a substrate configured to facilitate secure connection of the USB plug while inserted in the receptacle.

19. The system of claim 13 in which the receptacle further comprises a recess to receive the USB plug.

20. The system of claim 13 in which the receptacle is formed in an unshrouded configuration that lacks a recess.

21. A method of acquiring data, the method comprising:

establishing a connection between a receptacle to a living subject from which biometric data is to be acquired via one or more sensors having electrode leads coupled to a living subject, the receptacle having a connection prevention mechanism comprising a rib that prevents connection of a standard USB plug to the receptacle;

connecting a data acquisition device having a modified USB plug to the receptacle having the connection prevention mechanism, the modified USB plug being configured such that the modification comprises a slot that defeats the receptacle'"'"'s connection prevention mechanism while facilitating interconnection of the modified USB plug with standard USB-compliant devices; and

acquiring living subject-related data via the one or more sensors having electrode leads coupled to a living subject using the connected data acquisition device.

22. The method of claim 21 further comprising:

disconnecting the data acquisition device by unplugging the modified USB plug from the receptacle having the connection prevention mechanism; and

connecting the data acquisition device to an electronic device having a standard USB receptacle.

23. The method of claim 22 wherein the electronic device having the standard USB receptacle comprises a computer system.
