‘Sentry drone' warning system to help ‘Hong Kong low-altitude economy fly high'
A new 'sentry drone ' system is expected to help Hong Kong's low-altitude economy fly high, providing early alerts about navigation signal interference to ensure flight safety and reduce accidents, the transport minister has said. Secretary for Transport and Logistics Mable Chan offered the upbeat assessment in a post on her weekly blog on Saturday, saying she had recently taken a look at the system, developed by local company Aerovision Technology, which has applied for a Chinese patent covering Hong Kong. The 'Sentry Drone System for Early Alert of Global Navigation Satellite System (GNSS) Interference' uses innovative AI algorithms to patrol designated drone operating areas and provide warnings to operators to ensure flight safety. A GNSS is susceptible to interference such as jamming, spoofing – where malicious fake signals are transmitted to deceive a receiver – and certain solar effects, which may endanger flight safety and can lead to major accidents. 'We are confident that once this system successfully 'takes off', it will reduce safety risks associated with drone flights, allowing us to discuss lowering drone insurance premiums with the insurance industry, ultimately benefiting the entire low-altitude economy,' Chan said.

Hong Kong to deploy robotic dogs to combat chikungunya amid rising imported cases
Hong Kong will deploy robotic dogs as part of its enhanced mosquito-control efforts to curb the chikungunya virus, as the number of imported cases is expected to rise, the environment chief has said. Secretary for Environment and Ecology Tse Chin-wan revealed the new measure on Saturday after the number of imported cases of the mosquito-borne disease increased to nine the previous day. He said the government was exploring the use of new technology, including trialling a robotic dog next month. It will be used to carry and spray mosquito insecticide in rugged areas that are difficult for control teams to access on foot. 'Starting from next month, we will conduct a trial using a robotic dog to spray insecticide on hillsides and other places that are difficult for control teams to access,' he told a radio programme. 'This initiative is aimed at reducing burden on frontline staff during hot weather. If the trial proves successful, more robotic dogs will be deployed and the government will continue to research other new mosquito-control methods.' Tse added that the government's current mosquito-control measures were similar to those used during previous dengue fever outbreaks, saying he was confident the Chikungunya situation could be contained.

Nvidia's efforts to please both US and China get harder as H20 becomes bargaining chip
On his visit to Beijing in July, Nvidia CEO Jensen Huang received a rock-star welcome as he announced to Chinese state media that Washington had assured the company that export licences for its H20 chips would soon be granted. Warmly greeted by Chinese entrepreneurs and government officials, Huang – who wore a Tang suit and addressed the audience with his rusty Mandarin at the state-backed China International Supply Chain Expo – earned national fame overnight. Just two weeks after Huang concluded his third visit to China this year, the company saw its fortunes take a dramatic turn. On July 31, the Cyberspace Administration of China (CAC) said it had summoned Nvidia executives to question them about the security of its H20 chips. The powerful regulator said the inquiry was partly due to US lawmakers demanding the installation of tracking features into chips for export. That led to a back-and-forth between Nvidia defending the integrity of its chips and intensified pressure from state media for the company to demonstrate its security credentials.
