Accubeat – Cyber And Anti-Spoofing Solutions
Precise time, frequency and phase are all key elements in critical sectors such as Power and Utility Companies, Financial and Banking markets, Mobile and Computer Networks. In most cases GPS (or GNSS) is used to as a convenient and inexpensive means to obtain very accurate time which can be traced to the UTC (Coordinated Universal Time).
However, it is a well-known fact that the satellite signals coming from the GPS/GNSS units in space are precariously weak and these signals can easily be blocked, jammed or spoofed (delivering bogus signals to the GPS/GNSS receiver) intentionally or unintentionally. A group of researchers have demonstrated how a relatively simple spoofer can cripple an entire power network causing electrical outages to millions of subscribers within minutes.
Recognizing and understanding these threats, AccuBeat has developed and patented products and solutions to protect customer most critical assets, networks, platforms and infrastructure and ensure continued and secure operation even in a GPS/GNSS denied environment. These solutions include their unique and patented Time FireWall™ – a plug and play solution designed to protect customer legacy equipment without the need to replace existing equipment. AccuBeat also offers the AR50A – a portable timing dissemination case for instances where jamming or spoofing prevent an initial connection to a GPS/GNSS signal.
GP:50 Pressure Transmitter In Engine Test Stands
Engine test stands, also called Dyno’s, require precise measurement of various parameters such as pressure, temperature, load and flow. With today’s advanced data acquisition, higher accuracy and faster response sensors are required. Today’s engines operate more efficiently, and many times with higher pressure and temperatures. Choosing the correct pressure sensor for customer test stand is critical to meet the EPA or fuel efficiencies requirements.
GP50 240/340 series offers an economical, higher accuracy, compact design that meets the rugged demands of hydraulic and pneumatic pressures found in Dyno’s.
The model 241/341, GP50 most accurate pressure transducer, is designed specifically for automotive test stand applications and incorporates their proprietary digital correction circuit technology to provide high accuracy and high thermal stability. This circuit design provides some of the highest thermal accuracy in its class with an optional compensated temperature range from -40 to +250 ºF (-4.4 ºC to +121.11 ºC).
GP:50 Pressure Transmitter In Hydrogen Industry
GP:50 is staying on the cutting edge of the hydrogen industry, providing pressure and temperature transmitters for applications in both OEM fueling stations and cryogenic storage applications
Any unit that has 316L wetted parts is acceptable in Hydrogen gas, so Models like the 1003 series are good for larger OEM fueling station applications.
For cryogenic storage of hydrogen, the installer needs to use something like a siphon tube, see attached picture. Siphon tubes keep the liquid hydrogen from coming into contact with the sensor/ transmitter. This keeps the temperature at the sensor above cryo temps (usually -40 deg F or hotter) so typically a Model 311 or 340 series would work as long as you get 316L or Nitronic 50 wetted parts.
HSI Sensing Reed Switch In Pacemaker
HSI Sensing developed the new HSR-0025 reed switch to match the footprint of the MEM device, facilitating a seamless product integration which eliminated the need to cease their client’s pacemaker production schedule.
HSI Sensing continues to advance the reed switch industry by providing the world’s smallest reed switches the most sensitive reed switches. Their consistent quality with full traceability to raw materials ensures high performance standards. To date, HSI is still the go-to reed switch provider for the medical industry as they continue to produce the switch with the smallest profile (height – less than 0.9mm).
Knowles Capacitors For Electric Vehicle Drivetrains
The concept of the Electric Vehicle (EV) market is hard to miss nowadays. We increasingly see EVs on the streets and charging stations are becoming part of the landscape.
Modern EV’s, HEV’s and PHEV’s are sparking a revolution in the capacitor technology used in the control electronics. Higher temperatures inside the control circuits mean that conventional plastic film capacitors are no longer suitable for all applications and ceramic MLCC’s are now being increasingly used, with the added benefits that MLCC’s are generally surface mount direct to boards, yielding greater efficiency of assembly and allowing shorter circuit tracks with lower inductance. In many cases this last point allows lower capacitance values to be used, meaning that smaller components or less components can be used.
With the broadest range of AEC-Q200 approved MLC Capacitors, Tandem and Open Mode MLC capacitors, X8R High temperature MLC capacitors and EMI filters up to a voltage rating of 1kV at Knowles Precision Devices we provide for the requirements of EV and HEV systems.
Piconics Conical Inductors – A Broadband Microwave Choke
The Piconics’ broadband conical inductor is ideal for applications ranging from test instrumentation to microwave circuit design. The broadband inductor makes an excellent bias tee for use in communications platforms and RF test set-ups. The unique broadband response of the coil is attributed to its precision winding, selective gold plating and powdered iron filling.
Bias Tees are passive components whose function is to combine a dc bias voltage to a high frequency AC signal. The Piconics Broadband Conical inductor features a bandwidth extending from 10 MHz to 65 GHz with no resonance and flat across the full band. This allows the full band to be utilized in signal transmission. Applications include 40 GB and above data transmission systems and RF and Microwave AA radio platforms.
With the increased demand for fiber optic transmission lines, active devices with extremely broad bandwidths are in greatest demand. The power supply must be isolated from the active fiber optic device in order to drive them without damage. The broadband conical inductor solves this isolation problem over the full band by means of a single device. This single conical inductor will replace multiples of narrow band inductors in series.
Tekscan Flexiforce Sensor In Quantifying Robotic Grip
As technology advances, more and more minimally-invasive surgical procedures are being performed by complex robotic systems. These systems are designed to make specific actions with a high level of consistency.
A robotic surgical system manufacturer wanted to understand a robot’s surgical grip force, and evaluate its hinge design. A high-resolution pressure mapping sensor was placed between different gripper prototypes, to read the pressure distribution and grip force administered by the robot in real time.
In a separate but similar concept, researchers from the University of Los Angeles California School of Medicine developed a surgical gripper training device utilizing a FlexiForce sensor. The sensor was encased within a thin plastic cover on either sides of the gripper ends, which was used to measure the force exerted by the surgeon. The haptic feedback would be transmitted to the surgeon via a headband apparatus, which would prompt a tapping sensation on the surgeon’s forehead. If too much force was being applied, the apparatus would tap faster, instructing the surgeon to loosen their grip.
