One press advances the year by one, pressing the Volume Down button for longer advances the year by 10. When the correct date is displayed press the Toco Zero button once. You are then prompted to enter the time if different to that displayed. This works in a similar manner to the date with the Volume Up button advancing the hours and the Volume Down button advancing the minutes. When the correct time is displayed press the Toco Zero button once. You are then prompted to enter the Toco Base Line offset. This sets an artificial zero line for the toco transducer above zero, it can be set by pressing the Volume Up or Volume Down buttons for a value between 0 - 20. After setting this value the Toco will be set to this every time the Toco Zero switch is pressed, and allows small negative Toco excursions to be seen on the chart. When the correct time is displayed press the Toco Zero button once. You are then prompted to enter the Toco Filter Value. This sets the filtering within the monitor to produce a smoother Toco trace if required. ( The filter can remove some of the maternal breathing artefact). It is set by pressing the Volume Up button for a value soothing value between 1sec and 2sec.. When the correct filter value is displayed press the Toco Zero button once. You are then prompted to enter the Toco Range. This sets the response of the Toco transducer to either a full scale of 100 or 200 on the chart print out. It is set by pressing the Volume Up button for a value between 100 and 200.. When the correct range is displayed press the Toco Zero button once.



You are then prompted to enter the Chart recorder speed. This sets the initial turn-on speed of the chart recorder. Then once the chart is running the speed can be further changed to 1 ,2 or 3 cm/min. It is set by pressing the Volume Up button for a value of 1, 2 or 3 cm/min.. When the correct speed is displayed press the Toco Zero button once. You are then prompted to select the Data Block on or off. The Data Block is printed at the start of each recording, this function can be disabled by setting Data Block to off. It changes from on to off and back again by pressing the Volume Up button.. When the Data Block is set to your requirements press the Toco Zero button once. You are then prompted to select the Tachycardia Alarm on or off.

Ultrasound Technologies Ltd Circuit Description Power supply Circuit

The 240/110 VAC supply enters the FETATRACK 310 via an IEC double fused inlet / mains filter and switch and is fed to a torroidal transformer. The input supply voltage is stepped down to a nominal 24 VAC and is then bridge rectified by D19, smoothed by C140.

Regulated Supplies

The voltage regulators (U28 and U29) are fed from D19 at a voltage of around 36VDC. These oscillate at approximately 120 KHz transferring pulses of current into L12 and L14 respectively. The output of inductor is fed back directly into U28 (29) which at pin 1 is reference comparator and alters the pulses transferred into the inductor to obtain a stable voltage output. The output of U28 is 5V DC and U29 is 12V DC. Pulses of current in to inductor L14 are also taken into a charge pump to provide a stable –12V DC after regulator transistor Q14. D19 also supplies current to the printhead and motor drive circuits via Q13 and U30 which provides a stable 24V DC .

Printhead and Motor Drive Supply

The printhead requires pulses of current equalling 10A but for a very small amount of time, therefore current is taken from the charge built up in C130 rather than expecting the power supply to supply the pulses. Q13 is connected as an ON/OFF switch to the printhead voltage circuits to act as protection. An explanation of its operation can be found in section PRINTER INTERFACE. When ON, current is fed to U30 connected as a variable voltage regulator with a range of +18 v to +24 v where VR1 adjusts this voltage.


Ultrasound Technologies Ltd Ultrasound Circuit Overview

The ultrasound circuit is built up of four discrete sections. These are: Oscillator and Transmitter amplifier Receiver and Detector Audio amplifier Signal pre-processing. These operate to produce a continuous wave of 2MHz ultrasound which is passed to the transmitter crystal in the transducer. The signal is then reflected from moving interfaces within the body to the receiver crystal in the transducer, amplified and then detected so the audio Doppler shift of that moving interface can be heard audibly or passed via signal pre-processing to the A/D converter for rate calculation. The circuit board has the option of two ultrasound circuits which operated at different frequencies, the operation of each is identical as so only one is described here. The current nominal frequencies are 2.1MHz for US1 and 1.8MHz for US2.

Oscillator and Transmitter output.

L4 forms an oscillator with Q4 and its associated capacitors producing a sine wave drive at the required frequency. This is fed via a high current output driver Q1 and output transformer L1.

Receiver and Detector

The reflected Ultrasound signal is fed via a resonant transformer L1 to the gate of Q3, the drain of this FET connects to the source of Q2 to form a cascode amplifier From the drain of Q2 the amplitude complex of the received signal is detected by passing the signal through a detector diode D3 . The raw low frequency heart complex is then amplified and filtered by U1 where its associated components form a bandpass filter amplifier with a bandwidth of 150Hz to 1KHz. This signal is passed to the audio section and the signal pre-processing .

Audio Amplifier

The audio signal then passes to a input selector U25 where the user can select via the front panel which Ultrasound channel will pass to the audio circuits and then to digital gain control U24 and buffer amplifier U32, where the volume setting is determined by the microprocessor subject to the user setting. From here the gain controlled signal is fed to the input of a monolithic power amplifier U27 and from here to the loudspeaker at J11.


Ultrasound Technologies Ltd Signal Pre-processing

The detected audio complex is fed to U5 a bandpass amplifier where the filter characteristics are arranged to reject signals below 150Hz and above 1KHz , and the output is taken do a digital AGC U3. The amplitude stabilised signal is then amplified and full wave rectified by U2 . This full wave rectified signal is then buffered and smoothed by an active filter. The smoothing is achieved by the low pass active filter having a 3db at 5Hz hence giving the average value of the audio complex. This signal is then passed to the A/D converter stage of the cpu U8 for further digital signal processing .

Toco Circuit

A stabilised 5V is fed to the toco transducer along with 0V which form the excitation of a Whetstone bridge in the transducer. The Differential output of the transducer is fed via a high gain differential amplifier U26 to a low pass filter U32 for signal smoothing into the A/D converter U11 further digital signal processing U8. Toco Zero is automatically adjusted by D/A converter U31 providing an offset voltage into the input of U32 . Overall gain is adjusted by VR2.


Ultrasound Technologies Ltd Microprocessor Circuit

The microprocessor circuit is arranged around MC68HC812 a fast second generation central processing unit (CPU). When power is applied to the circuit a monitor circuit waits for the power rail to become stable and then 100 ms later takes the reset on the CPU high (logic 1) to 5 v. This starts the CPU working by reading the bytes at the very top of its memory map from the EPROM (ROM). This shows the CPU the start position in ROM from which to start executing. This sets up all the peripheral devices, which includes an interrupt timer, starts the system clock which consists of interrupts from the cpu to the watchdog ic at the rate of 1 every millisecond. As all functions are time dependant nothing starts without this clock. The CPU now reads all the preset variables from the battery protected RAM within the real time clock. The battery source is a lithium 3.6 v cell with a nominal life of 10 years.

After the CPU has loaded the variables it rums a system check for any internal problems which are reported on the system display. Selection of the individual devices is controlled by cpu internal the chip select circuits. Most analogue signals eventually require digital signal processing for display, chart recording or digital transmission, the signals are presented to CPU, where an internal 8 bit A/D converter with an 8 way multiplexed input converts the signals to digital form. The converter accepts unipolar signals of 0 - 5 v.. The CPU with the display and keyboard circuit using on chip peripheral interface , as well as detecting selection of ultrasound and the presence of an Event keypress.

Printer Interface

A proportion of the micro-circuit is dedicated to printer interface and control, the primary interface circuit contains timers, serial drivers and peripheral drivers. The principal of operation of the printhead and motor drive circuit is as follows : Data is decoded by the software into bit positions within the allowable area of the printhead . This data is then passed in serial form with a clock signal into the printheads serial buffer. The data is latched by a pulse from the cpu via CMOS buffer, this gives added protection in the case of device failure. Data is then burnt onto the printhead by strobes 1 to 4 from the cpu which last less than 1 mS . Under normal conditions with the printer OFF there is no supply connected to the printhead or chart motor. Only when printing is requested does the cpu turn on the 24VDC supply. The cpu also drives the chart recorder stepper motor via the high current microstep interface.

Data Storage (optional)

Full resolution patient data is stored on the optional data file when fitted to the unit. The file can store in excess of 48 hours of data that can be subdivided into 16 separate patient files. The data can be recalled to strip chart recorder or to UltraTrace fetal PC software. The Data file card is fitted to the serial 2 channel of the controller card.
