BLOOD-FLOW SENSOR KYOCERA
Kyocera has developed one of the smallest known optical blood-flow sensors, which measures the volume of blood flow in subcutaneous tissue. With the sensor, Kyocera is researching a variety of mobile health (mHealth) applications such as monitoring stress levels or preventing dehydration, heatstroke and altitude sickness by studying trends or changes in blood-flow volume as alerts for these conditions and developing algorithms for detection.
Devices equipped with this new sensor will be able to measure blood-flow volume in subcutaneous tissue by placing the device in contact with an ear, finger or forehead (the sensor targets capillaries for measurement and cannot be utilised on all parts of the body; measurement site may depend on monitoring applications). When light is reflected on blood within a blood vessel, the frequency of light varies — called a frequency or Doppler shift — according to the blood- flow velocity. The new sensor utilises the relative shift in frequency (which increases as blood flow accelerates) and the strength of the reflected light (which grows stronger when reflected off a greater volume of red blood cells) to measure blood-flow volume.
The company developed this sensor as an integrated module, incorporating the laser diode and photodiode into a single ceramic package, based on its established expertise in miniaturisation technologies.
Featuring a high signal-to-noise ratio (S/N), small size and low power consumption (output: 0.5mW), the sensor can be easily integrated into a smartphone or wearable device for mHealth applications.

PAT100 SERIES Megger
The PAT100 series of hand held portable appliance testers enable simple, fast safety testing in all environments; including offices, shops and business units. It is ideally suited to training organisations, easy to learn to use, tough and reliable yet with full functionality.
With rubber armoured cases and fitted with hardened, scratch proof glass, the PAT100s are exceptionally tough instruments, well able to cope with the treatment they will encounter on site or in the van. They are the perfect tester to carry just in case your customers ask “Could you just test...”
There are 3 testers in the range:
PAT120 simple PAT tester offer Class I, Class II and power and extension lead testing with fixed pass limits; because it has two insulation test voltages it can be used to test IT and surge protected equipment.
PAT150 full functionality PAT tester adds to the offering Portable RCD (PRCDs) testing at 10 mA and 30 mA, separate tests for continuity, insulation, mains powered leakage testing and SELV measurements using the quick test (QT) button, and can be used for testing fixed appliances.
PAT150R is a rechargeable version of the PAT150.
