We’re grateful to be at CES 2023, where the momentum around solutions with Semtech’s LoRa® devices and the LoRaWAN® standard is incredibly strong. This morning, we had the pleasure of connecting with a wide range of customers, LoRa ecosystem partners and industry experts to discuss the powerful impact of low power, long range Internet of Things (IoT) technologies on enabling a smarter, greener and more resilient future for our planet. The journey to lower carbon emissions — and, more broadly, help the enterprise achieve its environmental, social and governance (ESG) goals — is a cornerstone to Semtech’s innovation for a better world

Whether you are watching an action replay of a baseball game on a giant screen at a stadium, a movie on your large-screen TV or streaming a video on your laptop computer, a high-quality audiovisual (AV) experience is always expected. Ultra-High-Definition Serial Digital Interface (UHD-SDI) and High-Definition Multimedia Interface (HDMI) are two standards for digital AV transmission. UHD-SDI standardizes the transmission of uncompressed and unencrypted digital AV signals over coaxial or fiber optic cables. HDMI is a digital interface for transmitting high-definition, high-speed digital multi-track audio and uncompressed video signals from HDMI-compliant sources to AV displays. Even though they both can transport ultra-high-definition AV signals from a source to a display, HDMI is preferred to connect consumer gadgets such as computers, gaming consoles, Blu-ray/DVD players, televisions, projectors, etc. UHD-SDI is preferred for high-end applications such as professional indoor/outdoor video production and television broadcasts because it supports long-range transmission and a rugged connection with the help of a physical lock mechanism at each end of the cable. UHD-SDI coaxial cable can transfer signals up to 300 feet, whereas HDMI cables struggle with excessive signal degradation even within 50 feet. These two interfaces can be used together via an HDMI-SDI or SDI-HDMI converter. For example, as shown in figure 1, an HDMI display would be used for confidence monitoring of an SDI stream to avoid the need to use specially calibrated SDI-specific displays.

Not too long ago, my only fitness tracker was a pedometer in my pocket to measure my daily step count. Things have since changed very quickly. I now have a smartwatch on my wrist to track my daily activities, including steps completed, distance covered, calories burned, heart rate, and breathing pattern. I also receive alerts for messages, take calls, listen to my favorite podcast, and check the weather via my smartwatch. These are all in addition to seeing the accurate time of the day. Due to all these innovative features, wearing a smartwatch and using it as a fitness tracker is the trend for the health-conscious population worldwide. While these wearables help people remain fit, extra care needs to be taken by the manufacturers to protect these wearables from electrical overstress (EOS) and electrostatic discharge (ESD) generated from the body of the person wearing these devices.

集约化养猪(也称为“集约化养猪系统”)已成为养猪业的主要养殖方式。根据这种方法,猪被圈养在室内高放养密度的单独隔间或稻草棚内,让年龄相近的猪在共同的环境下成群结队地生活在一起。这样可以显著提高饲养效率,并经常采用新兴技术来维持猪的健康和保护猪的生长,如使用无线温度和湿度传感器监测猪舍内的各种环境参数。
