Patent ID: 8409095

Claim:
A sonographic control system comprising: a control interface comprising a first and second sensor positioned at a first location and a second location of the control interface, respectively, wherein the first sensor is configured to detect an object being in proximity to the first sensor and to generate, responsive to detecting the object, a first control signal, the first control signal indicating an increased level of adjustment of a parameter of the sonographic system, and wherein the second sensor is configured to detect the object being in proximity to the second sensor and to generate, responsive to detecting the object, a second control signal, the second control signal indicating a decreased level of adjustment of the parameter of the sonographic system; and a controller coupled to receive the first and second control signals, the controller configured to: initiate a hands-free operation of the sonographic system responsive to receiving the first and second control signals at the same time; generate, during the hands-free operation, an output signal to adjust the parameter of the sonographic system based at least in part on an increased or a decreased level of adjustment associated with the first control signal or the second control signal; and prohibit generation of the output signal to adjust the parameter of the sonographic system during hands-free operation responsive to receiving the first and the second control signal at the same time.
