1. A system for locating a blood vessel, the system comprising:
- a temperature sensor operable to output a temperature measure of a point on a surface of a skin; and
a processor in communication with the temperature sensor and configured to;
receive a first temperature measure from the temperature sensor,receive a second temperature measure from the temperature sensor,determine a differential between the first temperature measure and the second temperature measure, andgenerate an output signal indicating the presence of a blood vessel if the differential exceeds a threshold.

Abstract
Systems and methods for locating a blood vessel are described. One described method includes receiving a first temperature measure associated with a first point on a surface of a skin; receiving a second temperature measure associated with a second point on the surface of the skin, and determining a differential between the first temperature measure and the second temperature measure. The method further includes generating an output signal indicating the presence of a blood vessel if the differential exceeds a threshold.
