Connector interface system for data acquisition
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.
1. A wearable electrocardiogram (ECG) data acquisition device comprising:
a lanyard configured to be worn around a living subject's neck;
one or more electrode leads each configured to connect to an electrode on the living subject;
a receptacle connected to the lanyard and the one or more electrode leads;
a removable USB data connector on the wearable ECG data acquisition device configured to:
receive ECG data signals from the one or more electrode leads; and
connect with (i) a standard USB interface and (ii) with the receptacle configured to prevent interconnection with the standard USB interface.
2. The device of claim 1 , wherein the data connector comprises a feature that defeats a connection prevention mechanism in the living subject-connected receptacle.
3. The device of claim 2 , wherein the data connector comprises a slot that mates with a rib in the living subject-connected receptacle.
4. The device of claim 1 , further comprising circuitry to store, process, and/or transmit the received data signals.
5. The device of claim 1 , wherein the standard interface is a physical interface.
6. A wearable ECG data acquisition receptacle comprising:
a lanyard configured to be worn around a living subject's neck;
an input configured to receive data signals from one or more ECG electrode leads each connected to an electrode on the living subject; and
a connection prevention mechanism on the wearable ECG data acquisition receptacle that is configured to:
prevent interconnection with a standard interface, and
facilitate insertion of and electrical connection with a removable connector having a feature that defeats the connection prevention mechanism.
7. The receptacle of claim 6 , wherein the receptacle comprises a rib that mates with a slot in the data connector.
8. The receptacle of claim 7 , wherein the rib is formed along a center portion of the receptacle.
9. The receptacle of claim 6 , wherein the data connector is configured to receive biometric data signals from the living subject.
10. The receptacle of claim 6 , further comprising a substrate configured to facilitate secure connection of the data connector while inserted in the receptacle.
11. The receptacle of claim 6 , further comprising a recess to receive the data connector.
12. The receptacle of claim 6 , wherein the receptacle is formed in an unshrouded configuration that lacks a recess.
13. The receptacle of claim 6 , wherein the standard interface is a physical interface.
14. A wearable ECG data acquisition device comprising:
a lanyard configured to be worn around a living subject's neck;
one or more electrode leads each configured to connect to an electrode on the living subject;
a receptacle connected to the lanyard and the one or more electrode leads;
a removable USB plug configured to connect with (i) a standard USB-compliant device and (ii) the receptacle, wherein the receptacle is configured to prevent interconnection with standard USB plugs.
15. The device of claim 14 , wherein the USB plug comprises a feature that defeats a connection prevention mechanism in the living subject-connected receptacle.
16. The device of claim 15 , wherein the USB plug comprises a slot that mates with a rib in the living subject-connected receptacle.
17. The device of claim 14 , further comprising circuitry to store, process, and/or transmit the received data signals.
18. A wearable ECG data acquisition receptacle comprising:
a lanyard configured to be worn around a living subject's neck;
one or more electrode leads each configured to connect to an electrode on the living subject;
a connection prevention mechanism that prevents interconnection with standard USB plugs but that allows removable insertion of and electrical connection with a modified USB plug having a feature that defeats the connection prevention mechanism.
19. The receptacle of claim 18 , in which the USB plug comprises a slot that mates with a rib in the living subject-connected receptacle.
