MicroLoop - System Overview

MicroLoop MK8 System

The Micro Medical MicroLoop is a data recording spirometer consisting of a hand held microcomputer unit incorporating a high resolution, colour touch screen, USB interface and transducer ports. Supplied with the microcomputer is a Cradle base unit, Bi-directional transducer, disposable mouthpieces, mains adapter, nose clip and USB cables. The MicroLoop is powered by internal Nickel Metal Hydride cells or by the mains adapter supplied, either connected to the cradle or directly to the MicroLoop unit. When testing a subject, the Bi-directional transducer is plugged into the microcomputer unit. The Bi-directional transducer is used to measure the subjects expired flow and volume in accordance with the operating manual.

Bidirectional Transducer

The Micro Medical digital volume transducer consists of an acrylic tube with a vane positioned between two swirl plates. The low inertia vane is attached to a stainless steel pivot that is free to rotate on two jewelled bearings mounted at the centre of the swirl plates. As air is passed through the transducer a vortex is created by the swirl plates that causes the vane to rotate in a direction dependant upon the direction of airflow. The number of rotations is proportional to the volume of air passed through the transducer and the frequency of rotation is proportional to the flow rate. The transducer housing consists of a main body that contains a pair of light emitting diodes (LED’s) and phototransistors. The transducer is fixed to the mouthpiece holder that pushes into the main body and is captured by an “O” ring seal. The LED’s produce infrared beams, which are interrupted by the vane twice per revolution. This interruption is sensed by the phototransistors. The output from the collector of each phototransistor will be a square wave with a phase difference between the two of + or - 90 degrees depending upon the direction of flow. The square waves are detected by a microprocessor that measures the period of each pulse and transmits that information to the main unit via a high-speed asynchronous serial link. There is no routine maintenance required for the transducer other than cleaning according to the instructions in the operating manual.

MicroLoop Mk8 Repair

Disassembling the MicroLoop Mk8 for Repairs

1. Disconnect the mains power supply

We recommend that you use a Pozidriv No. 1 screwdriver for the following

instruction.

2. Place the MicroLoop Mk8 face down on a soft surface. Remove the four screws in the lower

moulding. Put the screws to one side. 3. Turn the unit face up before easing the upper and lower mouldings apart. 4. Taking all precautions against static damage, lift the MicroLoop PCB and display out of the bottom

moulding and place on an antistatic work surface. Note that the battery is secured to the bottom moulding by an adhesive pad.

5. Reconnect the power supply to the MicroLoop Mk8 charging socket 6. The MicroLoop is now ready for fault finding.

Reassembling the MicroLoop after repairs

1. Disconnect all mains power supplies. 2. Place the MicroLoop PCB and display assembly into the MicroLoop bottom moulding. 3. Insert the top and bottom end panels into the bottom moulding. It may be necessary to lift the PCB

slightly in order to fit the connectors through both end panels. 4. Ensuring that the keys do not fall out, position the top moulding over the bottom moulding and

ensure that they both mate correctly.

We recommend that you use a Pozidriv No. 1 screwdriver for the following

instruction.

5. Place the MicroLoop Mk8 face down on a soft surface and replace the four screws in the lower

moulding. 6. The MicroLoop Mk8 is now ready for operation.

Circuit Descriptions

Microcomputer Unit

Overview (105-01) and Micro controller (105-02). The drawing 105-01 is a hierarchical block diagram showing the connections of the sub-sections. The rest of the drawings are sub-sections and are described in detail below. U1 is a Sharp LH79520 32 bit microprocessor with 32K of Cache Ram, and no internal flash memory. The system clock is supplied by 14.7456MHz crystal (X1). J1 is the JTAG interface for programming the unit. JP1 is the jumper that must be in place for programming, and removed for normal use.

Power Supply (105-03)

Battery Charger and Voltage Regulators

U6 serves as the battery charger and voltage regulators. The capacity of the battery is 1600mAh, and the voltage can vary between 3 and 4.2V. When powered from mains, the charging current is set at 500mA. When powered by USB, the unit can initially draw 100mA. When switched on, the unit can request up to 500mA from the USB host The 3.3V rail is used for the microcontroller, the reset circuit, jtag interface, buttons, rtc, eeprom, lcd display, touch screen, lcd backlight, sound driver, usb, flash, sram. The 1.8V rail is used for the microcontroller, flash, and the lcd backlight. U8 is used to generate the 5V rail. This rail is used for Micro Medical Transducers, sound driver, and USB hosting.

Fuel-Gauge

U7 is a fuel gauge which is powered by the battery pack. The fuel gauge estimates the remaining battery capacity.

Microloop8 Sensor Interface (105-04)

2 Sensor ports are available on the unit.

U10 is used to translate the levels from 3.3 to 5V. TR7 is used to switch the power on for MM Sensor 1. TR8 is used to switch the power on for MM Sensor 2.

7

Keypad, EEPROM, RTC (105-05)

Two buttons are available on the unit.

KEY0 is the ON/OFF button. KEY1 is the HELP button U13 is used to generate an interrupt to the microcontroller if either the on/off or help button is pushed. BAT2 is a lithium coin cell to give the RTC power for up to 10 years. U10 is the RTC and is clocked by a 32.768kHz xtal. D2 enables power to be drawn from the main 3.3V regulator when the unit is on. U25 is a 32Kbyte EEPROM. This is used to store general settings and calibrations.

Display Driver (105-07)

The 3.5” TFT LCD Display is driven directly by the main microcontroller. The display has a built in touch screen and LED backlight, all on the same connector (J8). U16, and U17 are used to invert 2 lines from the processor. U18 is the touch screen controller. U21 controls a constant current through the LED backlight of the display. U20 can adjust the current to which U16 has to control. U19 is a step-up switching regulator used to create the appropriate voltages for the display (AVDD approx 8V, VGH approx 15V, VGL approx –8V).

Sounder (105-08)

The sound driver includes a digital potentiometer and an amplifier. The digital potentiometer (U22) is used to adjust the volume, and the amplifier (U23) is used to drive the 16ohm speaker with the final signal.

USB Driver (105-09)

The cypress SL811HST (U24) is a host/slave USB controller, which can be used for communicating with a PC or an external printer. In host mode 5V power is supplied through TR13, and switched on with TR14. The chip has is clocked by a 12MHz crystal (X4).

Memory (105-10)

U28 is a 32Mbyte FLASH 28F256P30 used to store all program code, and the files/filing system. U29 is a 2Mbyte SRAM CY62167DV30 used to store all volatile memory, such as video memory, and program memory.

Fault Analysis

The following analysis is only a guideline and should be carried out in a logical sequence. If the fault is still apparent after the following suggestions then the unit should be fault found using the circuit descriptions and circuit diagrams provided.

When the unit is turned on there is no display present

-Ensure charger is turned on at the mains.

FVC readings are low

-Remove turbine from transducer housing. Taking the turbine, move it slowly through the air and check that the vane is not sticking.

The unit does not recognise that the transducer is connected

-Ensure that the Bi-directional transducer is correctly plugged into the MicroLoop. -Inspect the Bi-directional transducer cable and connector for damage.
