Delhi HC dismisses Umar Khalid's bail plea_我的网站

A |     New Delhi, Oct 18 (UNI) The Delhi High Court on Tuesday dismissed a bail application of JNU student leader Umar Khalid arrested in the 2020 Delhi riots case.

Justices Siddharth Mridul and Rajnish Bhatnagar after hearing argument from both sides dismissed the bail saying the court did not find any merit in the plea.

Khalid's counsel moved the bail plea submitting that the student leader has been falsely implicated in the matter and did not have any role in the violence of Delhi's Northeast area.

Police opposed it saying that Khalid was arrested on September 13, 2020 on the charges of Unlawful Activities (Prevention) Act (UAPA).

Police has charged Khalid, Sharjeel Imam, and several others person under the anti-terror law and Indian Penal Code for allegedly being the masterminds of the protests and riots in Delhi's Jamia and Northeast area in the December 2019 and February 2020 violence during the protests against the Citizenship (Amendment) Act (CAA) and the National Register of Citizens (NRC) that left 53 people dead and over 700 injured.

B |     8月25日消息，近日，保时捷公布一项车载音响创新技术，将氮化镓（GaN）半导体引入柏林之声3D高端环绕音响系统，主要用于400W低音炮功放单元。

C |     这是全球首个计划量产装车的氮化镓车载高端音响方案，预计2027年随新一代保时捷车型正式落地。    该项目由保时捷联合斯图加特大学共同研发，2023年年中立项，2024年春季完成原型开发，已经申请多项相关专利。         据介绍，氮化镓常见于手机快充头，相比传统硅基芯片，功率转换损耗更低，工作过程发热量大幅下降，用在音响系统上会专门负责400W低音炮的电压转换，输出功率保持不变的前提下，功放散热压力显著降低。    最直观的变化体现在散热硬件上：功放散热器重量可以减少约20%，电容、电感等周边元器件也能够同步小型化，整套功放变得更加紧凑轻巧。    此外，传统功放散热器大量使用铝材，而铝冶炼属于高耗能工艺，应用氮化镓后，散热器减重，直接减少铝材消耗，帮助降低零部件生产环节碳排放，实现减重与可持续的双重目标，对追求轻量化的跑车平台意义突出。         保时捷表示，这次升级核心是提升电源转换效率，并非单纯强化低音音量，更低的热损耗，也意味着车载电能浪费变少。    目前氮化镓仅率先应用在低音炮功放模块，保时捷也正在评估，未来把该半导体技术拓展至车内更多电源转换部件。    保时捷把快充领域成熟的第三代半导体移植到车载Hi-Fi上，也给汽车电子打开新思路，也就是在有限车身空间内实现更高功率、更少材料消耗。
