For the First Time Ever, Panasonic's Image Analysis Technology “3D Tracking” Integrated into Live TV Broadcast of World Cup Volleyball 2019

Osaka, Japan – Panasonic Corporation (hereafter referred to as “Panasonic”) developed its image analysis technology, “3D tracking” to make headway in the sports business. And this technology is being integrated into Fuji TV’s live broadcast of World Cup Volleyball 2019 being held from September 14 to October 15, 2019. This is the first time that this technology has been integrated into any TV broadcast. World Cup Volleyball is held every 4 years by FIVB (International Volleyball Federation) and it is one of the big 3 tournaments on par with the Olympic Games and the World Volleyball Championships.
“3D tracking” technology integrated into the World Cup calculates the trajectory, speed, height, angle, etc. of the ball and other objects by gauging in real-time the 3D location data of the relevant objects using images from multiple cameras. Within the broadcast, the 3D tracking data will be applied to Fuji TV’s volleyball analysis display system, “Motion Scouter (displays the height and speed of serves and spikes)” and “Trace Vision (displays the trajectory of the ball and the angle of serve receives, the time it took from the toss to spike)” and overlaid onto replay footage. This will provide the audience a new viewing experience that integrates a scientific approach by providing footage of the athletes’ performance and the progression of the game, but also various relevant data.
With 2020 on the horizon, interest in sports will continue to amplify. By further developing and providing its 3D tracking technology to other sports, Panasonic will help bring to life a new spectating experience as well as a tool for athletes to hone their skills.

Large Anechoic Chamber for Evaluating Communication Performance of a Whole Vehicle with 5G Equipment

Osaka, Japan–Panasonic Corporation has announced today that it has built one of Japan’s largest anechoic chambers*1in Yokohama City, Kanagawa Pref. to evaluate the communication performance of a whole vehicle through omni-direction while autonomous and connected cars are expected to rapidly become equipped with 5G equipment.
Radio equipment and antennas for 5G communication, which achieves broadband communication by using multiple antennas (MIMO*2, beamforming*3), may not provide their actual or discrete performance when they are incorporated into vehicles owing to the reflection of radio waves on the body and electromagnetic noise from other electronic devices. In this anechoic chamber, the communication performance of a whole vehicle can be efficiently evaluated.
The chamber also contributes to determining the optimum positioning of 5G radio equipment and antennas that satisfy both the vehicle design concept and communication performance in the early stage of vehicle design with an automobile manufacturer.
The evaluation system in this anechoic chamber has the following features:
1. Efficient omnidirectional evaluation
2. Evaluation of MIMO antenna communication performance
3. Evaluation of beamforming performance
While rotating the turntable on which a vehicle is placed through a full 360 degrees, the system can conduct omnidirectional evaluation by moving the simulated base station tower along an arc and changing the distance between the tower and the vehicle. The system can simultaneously evaluate data at up to 200 frequencies and achieves high measurement efficiency. Furthermore, Panasonic’s antenna engineers analyze measured data from each antenna and provide communication performance evaluation results of complicated MIMO antennas and beamforming.

Ultra-low quiescent current delivers longer battery life

TI’s TPS7A02 ultra-low-power LDO linear voltage regulator claims the industry’s lowest quiescent current of sub-25 nA, and doubles the battery life for applications using standard battery chemistries
By Maurizio Di Paolo Emilio, contributing writer
One of the most critical challenges in electronic design today is to reduce energy consumption. Power management is an important design consideration for many devices, particularly those that rely on a battery for operation. As a result, most systems use various power management operating modes.
Functions like standby, sleep, power save, hibernate, and shutdown are critical for designers to reduce power consumption and extend battery life. During each mode, the currents can easily vary from a few mA to nA during sleep phases.
The advent of wearable devices has made this task difficult, due in part to the need to use small batteries to ensure small factors. The trend toward smaller batteries to accommodate decidedly smaller, lighter, and more powerful electronics has led to several compromises. The internet of things (IoT) and all connected devices have increased this need, requiring a reliable operating mode for an extended period and in a variety of operating conditions. Battery-powered systems require careful partitioning, tight space utilization, and efficient use of the available charge.
The high efficiency of these devices is demonstrated above all during the necessary standby phase for an extended time. In these cases, the energy consumption is defined by the quiescent current (IQ), different from the shutdown current. It is the operating condition of the circuit when it is not controlling any load. The quiescent current is commonly confused with the quenching current, which is the current absorbed when a device is turned off, but the battery is still connected to the system.
Why ultra-low quiescent current?
While the active current consumption is an important factor for extending the life of a battery, the time of use of the battery itself also depends on the other operating modes, in particular, that of standby. The absorption current during the standby phase (Iq) must allow the device to wake up at any time to execute the requests from the microcontroller.
The Iq is the main exponent for the standby power consumption of an electronic system, and is an important design parameter in the modern low-power DC/DC converters used in power management circuits. Iq enables the evaluation of different factors like power dissipation for small loads.
Power management is generally made up of regulators, such as switching ones that increase or reduce the voltage or those with low dropout (LDO). Some involve more architecture and perhaps even a charger. Reducing Iq increases efficiency and, therefore, increases battery life by consuming less battery power.
Power design
Power management circuits include several DC/DC solutions for supplying the sub-components of the device, such as sensors and microcontrollers (MCUs). A low-power MCU influences the energy efficiency of the entire system. MCUs are available in different shapes, sizes, and architectures, but for a connected IoT device, a 32-bit ARM microcontroller is a good bet. These MCUs are well supported by multiple manufacturers, and it is relatively easy to develop robust and portable software.
The manufacturing processes to produce the electronic components also affect energy efficiency. For example, advanced CMOS processes help ensure proper battery usage while reducing consumption. The designers need to balance capacities and dimensions with efficient power management techniques. Increasing the energy efficiency of a system is a common way to offer long battery life.
The power management part involves the use of voltage supervisors to ensure that the entire power system works appropriately. If the voltage is interrupted, the monitoring solution must signal the error condition so that the rest of the system can shut down correctly. The quick start delay allows the detection of a voltage fault before the rest of the system turns on, providing maximum safety in dangerous conditions. Texas Instruments’ (TI) TPS3840 Nanopower high-input voltage supervisor with manual reset and programmable-reset time delay offers this type of solution with high accuracy (Fig. 1). 
Fig. 1: A functional block diagram of the TPS3840.
With the mobile device portfolio growing every year, lithium-ion batteries require special care with a specialized charge cycle to maximize cell life. Battery charging for wearables is challenging because batteries must be both small in size and capacity.
TI also offers the  BQ25619, a new switching integrated battery charger (IC) that supports a termination current of 20 mA. It enables 7% higher battery capacity, and reduces battery leakage down to 6% in ship mode. This device provides designs for more efficient medical and personal electronics applications such as hearing aids.
DC/DC solutions
The selection of the right power management devices for the application is linked to the architecture of the DC/DC solution. Elements that should be considered when selecting a DC/DC solution include the quiescent current (an ever-lower value always represents the ideal choice), and efficiency (the higher the percentage, the better the battery life will be). The ideal is to have an efficiency of >90% at the level of µA. Another parameter is the input voltage range that allows operation even in an almost “dead” battery condition.
Power management integrated circuits (PMICs) include over a dozen LDOs. LDOs are also integrated into microprocessors, graphics processing units (GPUs), and many other on-chip systems (SoCs). The two main categories of voltage regulators are linear voltage regulators (LDO) and switching regulators.
There is certainly a significant use of switching power supplies due to the advantages they offer in terms of power density and overall efficiency. However, LDOs are used due to their low noise output voltage, small size, and low cost compared to switching regulators. There is usually a compromise between achieving a very low Iq and at the same time complying with other key parameters such as excellent dynamic performance, low output noise, and high-power noise rejection.
TI introduced an ultra-low-power, low-dropout (LDO) linear voltage regulator, the TPS7A02, which claims the industry’s lowest Iq of sub-25 nA — one-tenth that of competing ultra-small devices. The new controller allows engineers to at least double battery life, and claims best-in-class transient response for faster wake-up, improving application response times and dynamic performance.
In addition, the small footprint enables designers to reduce the size of the end products, making it a winning choice for all wearable applications. 
The TPS7A02 can shrink the solution size by 70%, enabling engineers to add more functionality to their designs in space-constrained applications or lower system cost by using smaller boards.
The TPS7A02 is used in low-power applications such as in grid infrastructure, building automation, and medical equipment (Fig. 2). By using the device in wireless video doorbell and security camera designs, engineers can achieve 24 months or more of battery life (up to four times the industry standard).
“As consumers expect to recharge or replace batteries less often, there’s an increasing demand for electronics that offer extended battery life, higher efficiency, and smaller size. Low quiescent current plays a key role in helping engineers address all of those challenges,” said Mike Beckman, vice president, Texas Instruments. “That’s why Texas Instruments continues to focus on developing and delivering innovative, low-Iq DC/DC converters, LDOs, battery management systems, and other power supply elements that help engineers solve design challenges surrounding small, low-power, long-lasting industrial and personal electronics.”
Fig. 2: A block diagram of the TPS7A02.
TI also offers the TPS62840, an ultra-low-power switching regulator with operating IQ at 60 nA. The wide input voltage (VIN) range of 1.8 V to 6.5 V supports a variety of battery chemistries and configurations. It finds applications in many battery-powered, always-on industrial and personal electronics applications, including narrow-band IoT, grid infrastructure equipment, and wearables (Fig. 3).
Fig. 3: A TPS62840 evaluation board.
Both ICs operate at very low levels of quiescent current, offering a simple solution to help improve the battery life of any battery-powered device. An essential reduction in the quiescent current could make the difference in an application running for a few seconds, minutes, hours, or even days.

80-W DC/DC converter provides 10-year warranty

Cosel’s rugged 80-W DC/DC converter delivers long life and high efficiency for demanding applications
By Gina Roos, editor-in-chief
Cosel Co, Ltd. released a high reliability 80-W DC/DC converter, the MGF80, with a failure rate of less than 30 parts-per-million (ppm). All components used in the manufacture of the supply are selected for a very long lifetime, enabling the company to guarantee a 10-year warranty.
Designed for a range of demanding applications, the MGF80 series is available in two input voltage ranges: 9 V to 36 V, and 18 V to 76 V. A single-output version, the MGFS80, is available in four output voltages — 3.3, 5, 12, and 15 V, and can be adjusted within a range of +/-10% using a resistor bridge or potentiometer. A dual-output version, the MGFW80, is available in two, factory-trimmed output voltages, +/-12V and +/-1 5V.
Synchronous rectification and soft-switching technology contribute to the MGF80 series’ 94% typical efficiency. The MGF80 series operates over a  temperature range of -40°C to 85°C with a maximum case temperature of 110°C. Other features include overcurrent and overvoltage protection, and thermal protection that switches the unit off when the maximum allowable safe temperature is reached.
The devices have passed three-axis vibration testing equivalent to 10G and shock testing of 50G. Applications include industrial, IoT, and mobile equipment, particularly in demanding applications.
The MGF80 devices are packaged in a six-sided, brass, nickel-plated housing in an industry standard 50.8 × 25.4 × 9.9 mm (2 × 1 × 0.39 in.) footprint. The series provides an input-output isolation of 1500 VDC, and an input and output to case isolation of 1,000 VDC. It is UL62368-1, C-UL [CSA62368-1) and EN62368-1 approved, and has a CE mark 2014/35/EU. The MGFS80 and MGFW80 are RoHS compliant.
