Palakkad DRM inspects elephant intrusion detection system implementation
The Divisional Railway Manager (DRM), Palakkad Division, Arun Kumar Chaturvedi, inspected the ongoing implementation of the elephant intrusion detection system (EIDS) in the Kottekkad – Madukkarai section, a vulnerable stretch spanning Kerala and Tamil Nadu that has recorded wild elephant movements onto railway tracks. The EIDS is an initiative of Palakkad Division, Southern Railway, aimed at preventing elephant intrusions and enhancing the safety of both wildlife and train operations. It integrates an optical fibre–based sensing network with artificial intelligence–driven analytical modules to detect the presence and movement of elephants in real time. The system covers all identified elephant corridors along both the A and B lines of the section. Installation of the system has been completed on both the A Line and the B Line. At present, signal validation, fine‑tuning, and systematic reduction of unconfirmed (spurious) alarms are in progress. Pre-commissioning activities are targeted for completion by July 30. Using distributed acoustic sensing, sensors along the tracks capture vibration signatures (such as characteristic elephant footfall patterns) and relay data to the Distributed Acoustic Sensing unit located at Walayar. The AI engine and reference databases then localise any confirmed elephant presence to the exact kilometre. Verified alerts will be relayed without delay to the Station Masters of stations concerned, Divisional Control Office, Palakkad Division, any level crossings between the stations, and locomotive pilots via dedicated display and alert interfaces, enabling timely operational responses to avert incidents. The estimated project cost is ₹15.42 crore, fully funded by the Railways. During the visit, the DRM also inspected protection measures in the section, including solar fencing, rail fencing, clearance of vegetation on both sides of the track, and the functioning of railway‑constructed elephant underpasses.

AI system to track animals on 15km rail stretch, smart sensors will warn loco pilots of wildlife crossings
Dehradun: An Artificial Intelligence (AI)-powered intrusion detection system was cleared for installation along the 15km Motichur-Raiwala railway stretch to prevent wildlife from being hit by speeding trains. Officials identified five key points on this stretch as highly vulnerable to animal crossings and plan to deploy sensors and alarms to alert train operators and forest teams. The test run of the system will begin this week. Rajeev Sharma, senior consultant from the team implementing the system, said they received the go-ahead from the chief wildlife warden. He added that the animal intrusion system uses fibre optics and Distributed Acoustic Sensing (DAS) to detect animal movements close to the tracks. "It can also sense other activities like train movement, digging and cable damage. Once the system picks up an acoustic signal, it immediately sends alerts to the station master, loco pilot, and frontline forest staff. Alarm hooters and audio-video signals are also triggered for faster response. This system will significantly improve animal safety and enhance railway security by giving advance warning of wildlife movement," Sharma said. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giá vàng đang tăng mạnh trong năm 2025 — Các nhà giao dịch thông minh đã tham gia IC Markets Tìm hiểu thêm Undo The state has a high density of wildlife including tigers, leopards, elephants, and ungulates. As per forest department data, elephants and leopards are among the most frequently hit species, especially in the Shivalik Elephant Reserve, which spans Garhwal and parts of Haldwani, Tanakpur, and Ramnagar in Kumaon. Since Uttarakhand was formed, at least 12 elephants have been killed by trains on this route. Similar systems have already been tested along elephant corridors in Kerala, Tamil Nadu and Odisha. These use buried fibre optic cables to detect movement and vibration up to 30-40 metres from the track. In Tamil Nadu's Walayar-Kanjikode section, trials showed successful real-time alerts sent to station staff and train pilots. The technology was also trialled along the Howrah-Mumbai route, using elephants during testing to calibrate detection accuracy. Globally, DAS has found wider railway applications, from detecting rockfalls to sensing rail fractures and trespassing. By turning existing fibre infrastructure into large-scale acoustic sensors, railways can track multiple hazards in real-time.

Murata Launches World's First High-Frequency Filter Using XBAR Technology for 5G, Wi-Fi 7, and Future 6G Networks
KYOTO, Japan--(BUSINESS WIRE)--Murata Manufacturing Co., Ltd. (TOKYO: 6981) (ISIN: JP3914400001) has announced the mass production and commercial shipment of the world's first *1 high-frequency filter using XBAR technology *2. Developed by combining Murata's proprietary Surface Acoustic Wave (SAW) filter expertise with XBAR technology from Murata's subsidiary Resonant Inc., it enables the extraction of desired signals while achieving both low insertion loss and high attenuation. These features are critical for the latest wireless technologies, including 5G, Wi-Fi 6E, Wi-Fi 7, and emerging 6G technologies. The demand for reliable high-frequency communications continues to grow in response to the widespread deployment of 5G and the future development of 6G. Simultaneously, wireless local-area network (WLAN) standards such as Wi-Fi 6E and Wi-Fi 7 are expanding into higher frequency domains to accommodate ultra-fast data rates. Filters used in these applications must address key challenges, such as preventing out-of-band interference, maximizing system battery performance, and meeting strict space limitations. Traditional approaches using Low Temperature Co-Fired Ceramic (LTCC) or conventional Bulk Acoustic Wave (BAW) filters often fall short in these performance areas. Murata's new XBAR-based filter addresses these limitations by achieving high attenuation performance while maintaining a wide bandwidth and low signal loss. The XBAR structure itself excites bulk acoustic waves using comb-shaped electrodes and a piezoelectric single-crystal thin film, enabling performance beyond the reach of conventional filter structures. It effectively removes high-frequency interference, even in bands above 3 GHz, allowing for clearer signal detection and better performance, contributing to high-speed, high-capacity, and high-quality wireless communication. Key performance parameters include a passband of 5150–7125 MHz, a typical insertion loss of 2.2 dB, and a typical return loss of 17 dB. Typical attenuation figures are 11 dB at 4800–5000 MHz, 28 dB at 3300–4800 MHz, 27 dB at 7737–8237 MHz, and 26 dB at 10300–14250 MHz. The new filter is targeted at devices with embedded wireless functionality, including smartphones, wearables, notebook PCs, and communication gateways, offering an optimal balance of performance and cost efficiency. Murata will continue to drive innovation in filter technologies to support the evolution of wireless communications, and expects this architecture to scale further, with future product generations capable of operating effectively in ultra-high frequency bands above 10GHz.

Meghan Markle Shares Prince Harry's Unique Royal Parenting Style With Prince Archie & Princess Lilibet
Prince Harry is a hands-on father. That's what Meghan Markle is making sure royal fans know — his best role in life is as Prince Archie, 6, and Princess Lilibet's, 4, dad. His proactive role in his children's lives was seen in the Duchess of Sussex's sweet Father's Day tribute to her husband on Instagram. The adorable moments were captured in a tender video and gave her followers a more intimate look at their personal lives — and they look happy! Meghan shared her love for Harry by captioning the video, 'The best. Happy Father's Day to our favorite guy.' She added a two-pink-heart emoji and added Jason Mraz's single, 'Have It All (Acoustic) to the clip. More from SheKnows Megan Fox & Machine Gun Kelly Reveal Their Newborn Daughter's Name - & It's Both Poetic & Edgy Most of the footage was from Archie and Lilibet's younger years (probably to protect their privacy), but we can't help but smile at the dad milestones Harry has been able to witness — from teaching his son how to ride a bike to taking a father-daughter beach walk with his daughter. It's the everyday activities his late mother, Princess Diana, appreciated despite her royal title. She tried to give Princes William and Harry a normal childhood even though they were very famous young boys. In the last year, the Duke of Sussex has doubled down on his decision to move to the U.S. after exiting the royal family – it was the right move for his family. 'I enjoy living [in the U.S.] and bringing my kids up here,' Harry at The New York Times' DealBook Summit in December 2024. 'It's a part of my life that I never thought I was going to live, and it feels as though it's the life that my mom wanted for me. I want my kids to grow up with the opportunity to be themselves.' Princess Diana's parenting style was imprinted on Harry at a young age even though she passed in 1997, he has never wavered from her teachings. 'My main goal is to be the best dad and husband I can be,' he added. It's not much different from what Diana told the press in her years as a royal. 'I will fight for my children on any level so they can reach their potential as human beings, and in their public duties,' she said in her BBC interview with Martin Bashir in 1995. Instead of having a household of staff raising her children, she made sure she was entrenched in William and Harry's lives. Harry has never doubted his mother's love and he's making sure Archie and Lilibet experience every ounce of that care through him — it's a way for Diana's legacy to live on. 'I can still feel the hugs that she used to give us,' Harry said in the 2017 TV documentary Diana, Our Mother: Her Life and Legacy. 'I miss that feeling. I miss having that mother to give you those hugs and that compassion that everyone needs.'Best of SheKnows Celebrity Parents Who Are So Proud of Their LGBTQ Kids Recent Baby & Toddler Product Recalls Every Parent and Caregiver Should Know About These Podcasts for Parents of Teens Will Make You Feel Seen

Young Kerry musician launches fundraiser to help her collaborate with Grammy winner
Lorraine, who hails from Lyreacrompane, released her first album All That I Can Be back in 2023 before releasing a deluxe edition of the same album earlier this year. Now she hopes to get back into the studio sooner rather than later on her sophomore outing, one that she hopes to collaborate on with none other than multi-Grammy award-winning musician (14 to be exact) by the name of Ron Block, the last of which came back in 2011 when his band Alison Krauss & Union Station won the award for Best Bluegrass Album. 26-year-old Lorraine is – as well as currently touring with The Hothouse Flowers – in the midst of preparing for her Glastonbury debut on June 28 when she will take to the Acoustic Stage, playing alongside amazing acts that she has loved and admired for years such as Nick Lowe, the Hothouse Flowers, Oisin Leech, Billie Marten, Gabrielle Alpin, and The Henry Girls. Collaborating with Ron Block on the new album will not come cheap though with Lorraine hoping that, with financial support from the public, she will be able to afford to fly to Nashville in Tennessee. Lorraine first connected with Ron earlier this year and she said that she is 'incredibly excited' to potentially head to Nashville to 'bring these new songs to life.' Writing on her Kickstarter fundraiser page, Lorraine had this to say: 'Streaming and the digital landscape of the music industry has made it very hard to sustain a career in music, let alone fund an album. That's why I'm asking for your support to help pay for the creation of this record. I'd be so grateful if you could contribute or share this with someone who might be in a position to do so. You can give as much or as little as you like and you can choose from any of the rewards [on the page]. Lorraine has budgeted that the entire trip will cost about €25,000 (the full breakdown of costs can be found on the Kickstarter page) and she has so far raised almost €5,000. There are some risks involved for Lorraine in her fundraiser if she doesn't reach her target goal, she said that she won't receive a single penny. If this fundraiser is successful I will be able to apply for my USA working visa and get to Nashville as soon as possible. I then face the challenge of raising the remaining €5000 through funding applications and gigging. Your help will break the back of the beast and make it possible for me to get started on what will be a really special record,' she said.
