Disclosed are systems and methods which power-down (reduce power to or deactivate) circuits in an ultrasound system during periods in which an acoustic signal is not being acquired, although image processing and other system functions are continued normally. Such circuits may be powered-down between each of a series of acoustic signal acquire operations, such as between acoustic signal scan lines and / or between acoustic signal scan frames. The circuitry which is powered-down between scan lines and scan frames may not the same, although some circuitry may be common to both. Embodiments may further operate to adjust the acoustic signal dead time circuitry power-down cycle, such as by adjusting acoustic signal frame rates. Power-down techniques may be utilized in addressing power issues and / or in controlling thermal aspects of the operation of an ultrasound diagnostic system.

The invention discloses an electric shock preventing power supply apparatus. The electric shock preventing power supply apparatus comprises an inserting-connecting part and a socket part arranged at the lower end of the inserting-connecting part; a connecting rod, a power connection sheet and a wire are included in the inserting-connecting part; inclined inserting rods, which are extended downwards, are fixedly arranged on the two sides of the connecting rod respectively; sliding frames are arranged in the upper end of the socket part in a left and right symmetrical and upward extended manner; a limiting block is arranged at the upper end of each sliding frame separately; a lower pressing groove is formed in each sliding frame; a first compression spring is arranged on the bottom surface of each lower pressing groove separately; a conductive sheet is glidingly matched and connected between two lower pressing grooves; the upward extended end of the first compression spring and the bottom surface of the conductive sheet are fixedly connected and are matched in a lower pressing manner; jacks are formed in the corresponding socket part at the lower ends of the inclined inserting rods; sliding grooves which are arranged symmetrically left and right are formed in the socket part among the jacks; a baffle fixedly connected with the socket part is arranged between the sliding grooves; a perforated hole which penetrates through the top wall of the socket part and is connected with the region between the sliding frames is formed in the upper end of each sliding groove; and a conductive pin is arranged in each perforated hole. The electric shock preventing power supply apparatus is simple in structure, can be automatically powered on in inserting and connecting and can be automatically powered off after pulling out, and is relatively high in power supply safety and relatively low in cost.
