The new flow sensor uses screen-printed thick-film thermistors and resistive heaters protected by a thin layer of Parylene-C to convert heat transfer to fluid flow velocity using King's law. The thick film substrate is connected to a small electronics board, which includes a TI MSP 430 microprocessor. The electronics manage power to the resistive heaters, and measure differential output across a four-wire bridge formed by four of the screen-printed thermistors. They also detect alarm conditions such as dry-line and reverse flow. Dry line is measured using a temperature rate-of-rise algorithm. Reverse flow is detected using a secondary resistive heater positioned in immediate proximity to a temperature measuring thermistor. When the flow direction is opposite to that of the normal ...
During the last decade, the world of electronics has experienced a surge in autonomous electronic devices. One last tether has prevented consumers from completely leaping into the wireless convenience - the power cord. Wireless power transmission (WPT) will remove the need for power cords for portable electronic devices including smartphones, tablets, laptops and more. More than 800 million wireless power transmitters and receivers are forecast for 2015 for mobile devices such as laptops, mobile phones, tablets, e-Readers and media players. Evidence is increasing that wireless power can be environmentally friendly. This technology is improving the capability of contactless charging and direct power for many applications from military to medical to consumer electronics.
Although WPT is moving forward, ...
Analysis of the stability of buildings is a needed measurement process for all buildings in the cities. Periodic monitoring of the structure for such damage is therefore a key step in rationally planning the maintenance needed to guarantee an adequate level of safety and serviceability. However, in order for the installation of a permanently installed sensing system in buildings to be economically viable, the sensor modules must be wireless to reduce installation costs, must operate with a low power consumption to reduce servicing costs of replacing batteries, and use low cost sensors that can be mass produced such as MEMS sensors.In this project MEMS accelerometer is used to sense the shaking of the building which in sends message signal ...

We named this solution NEM – Never Ending Memory. It is composed of very good known technologies. We just connected them a little differently.
The idea is very simple. We replaced Flash memory with dual port Flash memory, where second port is connected to the storage cloud through LTE interface. That is all.
Dual port Flash have a role of cache memory. It contains only small part of user’s data (few dozen gigabytes). NEM reports the capacity ...

The PMAL will be a compact multi-function laser device, integrated optionally at the external side of an astronaut’s suit.
It will be used as a Laser Doppler device – pointer – distance meter – emergency position indicator – morse signal beacon.
The laser beam will be selected in the visual wavelength and in safe margins of output power. Special attention must be given during the design of the PMAL, on product safety (e.g. short-circuit fire) and the possible effects on other equipment onboard the suit, the targets etc. (e.g HIRF) in the working environment of space.
The readings of the PMAL could be shown on the helmet mounted displays of the astronauts and could also be used as verification ...
Nation-crippling failures of Extra-High-Voltage (EHV) transformers from geomagnetic induced currents (GICs) caused by earth-directed solar coronal mass ejections (CMEs) have been quantified and impacts highlighted by our mass media for more than a decade. Unaddressed, durations of the power distribution outages will be determined by new/repaired transformer replacements available from very few suppliers.
Transformer protection schemes are intended to enable timely grid disconnections of transformers experiencing excessive GICs which shift excitation operating points that cause rapid thermal insulation damage (described below). Costs of the hardware associated with proposed approaches often appear attractive, but require costly high-voltage installations, inhibiting wide-scale implementation and creating vulnerability to inappropriate activation or compromise. Monitoring only GIC-caused Wye-grounding currents to justify switching (e.g., more than ...
With the introduction to new conductive inks and toners, printing circuits onto
unconventional materials is now possible. This project involves printing electromagnetic coils onto both sides of a paper substrate. With a simple hole punch the coil circuits can be connected in series with conductive ink, glue or foil.
The direction of the coils (left hand and right hand) are configured to cumulate the field for coils aligning front side and back side. However, each set repels the next set which are folded in a zig-zag pattern resulting
in a expansion or contraction (depending on electrical polarity).
This arrangement is very simple, low cost, bio-degradeable, and light weight.
Additional articulation can be accomplished by printing ...
