The stress hormone cortisol could be detected accurately by a straightforward bedside test, according to researchers at Rutgers University. They are using an electrode coated in an antibody that binds with cortisol to do the detection, and needed the counter electrode to be really close to keep sensitivity high and noise low. At a few microns apart, interdigitated fingers were ...

TDK-Lambda has introduced a series of ac-dc mains power supplies rated at 350W convection, 500W with forced air and 1kW peak. Called CUS350MP, the PSUs have medical and industrial safety certifications. Input can vary across 85 to 265Vac (with leakage current <300µA). Four output voltages are available: 24, 30, 36 and 48V, plus a 5V 300mA isolated stand-by voltage – remote on/off is also fitted ...

Bourns has introduced two series of high-grade surface-mount fuses, rated to 150°C. SF-0603SA-M and SF-1206SA-M have slow-blow characteristics, conducting for at least four hours at rated current, and clearing within 5s at room temperature and 2.5x rated current. They come in EIA 0603 and 1206 footprints respectively, and are of multilayer ceramic construction with protection against thermal shock, salt spray and mechanical ...

TFT displays can be integrated into a variety of installations, in industrial and commercial settings. Assemblies are typically made up of a touch panel or cover lens and the display, with an air gap between the two. When an external light source (natural sunlight or ambient lighting) enters the front of the assembly, the light passes through the touch panel ...

TrumPower is aiming at medical and IT applications with a range of single-output ac-dc mains power supplies capable of delivering 100W with convection cooling and 150W with 10 CFM forced air cooling. Called TWM150, they come in three styles: 51 x 76 x 30mm open frame 66 x 91 x 38mm u-channel 66 x 91  x 39mm enclosed Eight output ...

Sensirion and Nicolay have teamed up to offer an evaluation kit that measures air flow and pressure for human ventilator development. The companies already have an evaluation kit for proximal measurements of inspiratory and expiratory respiratory gas flow rates – Sensirion makes the flow sensors and Nicolay the connector and cable. “Having received many inquiries from ventilator manufacturers about whether we ...

Suitable for indoor and harsh environments as well as more unusual designs for indoor displays, the FLR-0959MLV0PCFA1  is a series of round displays by FutureLabs which are now available from Relec Electronics. The 9.5-inch TFT and PCAP (projected capacitive) displays have an active display area of 240mm. Resolution is 1540 x 1540 with 1000 CD/M2 brightness. They can be used in ...

Vox Power is extending the range of medical applications for its NEVO+600 and NEVO+1200 series of power supplies with two new 300W output modules. The dual slot OPA2 and OPA3 modules provide manually adjustable output voltages of 4.5 to 15V at 25A and 9 to 30V at 15A respectively, Vox Power states. “Vox Power’s NEVO+ power supplies offer system designers ...

Cosel has introduced 1,500W power supplies for medical and industrial applications with a serial interface for monitoring and control. Called PCA1500F, it has a universal input working across 85 to 264Vac and comes in 5, 12, 15, 24, 32 and 48V output versions. “All output voltages can be adjusted to near zero volts and operated in constant voltage or constant current ...

Scientists in France have demonstrated a lens-less infra-red spectral-imaging system for medical diagnostics, obtaining simultaneously morphological and biochemical information. Images at different wavelengths differentiate tumour cells “The combination of a set of lasers and lens-less imaging with an uncooled bolometer matrix allows biochemical mapping over a wide field of view,” said Grégoire Mathieu of Grenoble research institute CEA-Leti. “The project ...
