2- THEORY of OPERATION2.1 Overview
The Intelect/Genisys Ultrasound Therapy Systems are comprised of several PC board assemblies housed within acommon enclosure. These assemblies each support a distinct function in the product. The basic elements are UserInterface, Control Board, Ultrasound Board, Ultrasound Applicator, and Power Supply Circuits.
2.2 Power Supply Circuits
A universal input power supply provides all parts of the system with 12 volts DC. The supply is connected to the mainsat all times when the cord is attached. The power switch on the top of the unit, switch the 12V output of the powersupply to the different components in the system by way of the Power Distribution Board. The 12V supply is regulatedlocally at each PC board as required.
2.3 Control Board
The Control Board serves just as its name implies. It controls the operation of the ultrasound board, user interface andoptional accessories. The control board communicates to the ultrasound board through a proprietary 8-bit parallel bus.The control board drives the display. The control board reads the menu buttons. The control board also reads theamplitude and the contrast control on the system. Sound output is generated by the control board and routed to aninternal speaker.
2.4 Ultrasound Board and Applicator
The ultrasound board generates the 1 or 3.3 MHz output to drive the ultrasound Sound Head. The ultrasoundboard is accessed much like an I/O port by the control board. It can provide current and voltage informationabout the ultrasound output of the board. The calibration data for the Sound Head is passed through theultrasound board from the applicator up to the control board. By storing the calibration data in the applicatorthere is no calibration necessary for the ultrasound board. Calibrated Chattanooga Group Ultrasound Applicators,designed specifically for the Intelect/Genisys Ultrasound Therapy Systems, can be connected and operated toprovide accurate coupling and output.
2.5 User Interface and Accessories
The LCD display panel provides the operator visible feedback in the way of menu choices. Pressing the menubuttons makes selections from the menus. The control board interprets these user inputs and respondsaccordingly. Audible feedback is given as well for events such as keypresses and end of treatment.
The Optional Battery mounts in the system bottom and supplies 24 VDC to the power supply. The Power Supplydistributes the power required to the system as needed. The charging circuit for the battery is incorporated on theControl PCB. An icon on the display reflects the available amount of charge in the battery. When the system isconnected to an approved power outlet and a battery is installed in the system, the system will charge the batteryto full capacity. The incorporated charger will not overcharge the battery.
