一 |     The president of a Detroit synagogue was found stabbed to death outside her home Saturday morning, police and the synagogue said.The Isaac Agree Downtown Synagogue put out a statement later in the afternoon identifying the victim as board president Samantha Woll.Detroit police responded to a 911 call of an unresponsive person around 6:30 a.m. and found a body outside a home on Joliet Place. The woman, who was not immediately identified by investigators had suffered multiple stab wounds, police said."At this point, we do not have more information, but will share more when it becomes available. May her memory be a blessing," the synagogue said in a Facebook post.In an update shared on Sunday, the Detroit Police chief said in a brief statement that there is no evidence to point to the crime being motivated by antisemitism."The investigation into the death of Ms. Woll remains ongoing. At this time, however, no evidence has surfaced suggesting that this crime was motivated by antisemitism," Chief James White’s statement read.“DPD investigators are working with the FBI to forensically analyze all of the information obtained up to this point in an effort to ascertain the timeline that ultimately led to Ms. Woll's death. Individuals with information that may further this investigation are being interviewed,” his statement continued.Authorities are investigating Woll's death as a homicide, police said on Saturday."Police officers observed a trail of blood leading officers to the victim’s residence, which is where the crime is believed to have occurred," the police said in a statement.The investigation remains ongoing.A law enforcement official briefed on the probe told ABC News that the preliminary investigation has revealed there was likely no forced entry to Woll’s home.Woll's death comes as law enforcement agencies across the country are warning of increased anti-Semitic threats in light of the ongoing Israel-Hamas conflict.Woll had a long career in local politics and worked with several elected officials over the years, according to her LinkedIn page.She recently served as the political director for Michigan Attorney General Dana Nessel's re-election campaign.Nessel released a statement on X, formerly known as Twitter, expressing shock at Woll's murder."Sam was as kind a person as I’ve ever known. She was driven by her sincere love of her community, state and country. Sam truly used her faith and activism to create a better place for everyone," Nessel said in her post which included a photo of Woll.Woll also worked as a deputy district director for U.S. Rep. Elissa Slotkin, D-Mich., who also released a statement on X following her death."She did for our team as Deputy District Director what came so naturally to her: helping others & serving constituents. Separately, in politics & in the Jewish community, she dedicated her short life to building understanding across faiths, bringing light in the face of darkness," Slotkin said.Michigan Gov. Gretchen Whitmer said the state police will be assisting the Detroit Police department in the investigation."My heart breaks for her family, her friends, her synagogue, and all those who were lucky enough to know her. She was a source of light, a beacon in her community who worked hard to make Michigan a better place," she said in a statement.Other Michigan elected officials also expressed their condolences."Decades ago, I shared a day of joy with Sam at the dedication of the newly renovated Downtown Synagogue. It was a project she successfully led with great pride and enthusiasm. Sam’s loss has left a huge hole in the Detroit community," Detroit Mayor Mike Duggan said in a statement to ABC affiliate WXYZ. Woll's funeral was planned for Sunday afternoon, according to WXYZ.Anyone with information is urged to call the Detroit Police's Homicide section at 313-596-2260.ABC News' Ben Siegel and Josh Maroglin contributed to this report. 。    打造智慧工厂实现降本增效小小互感器，撬动十亿大产业近日，记者在位于沧州市青县经济开发区的青县择明朗熙电子器件有限公司1号厂房看到，一条条银色带材从非晶重力制带机中疾速喷出，经过卷绕、热处理、喷涂、绕线、灌胶、组装等多道工序后，制成各种规格的互感器。“互感器是电力系统的重要组成部分，主要供测量仪表、计量装置、继电保护装置等使用。”公司总经理周恩勇介绍，今年1月，电子元器件生产项目一期正式投产，预计年产磁芯1000吨、互感器1亿只，年产值达3亿元。

二 | 到2030年，这一省重点项目全部投产后，年产值将突破10亿元。作为一家高新技术企业，择明朗熙主要研发和生产纳米晶带材、纳米晶铁芯、电流电压互感器、霍尔电流电压传感器等产品。

三 | 产品广泛应用于工控仪表、智能电表、新能源汽车充电桩等多个领域，销售市场已拓展至16个国家和地区。过去，受限于场地狭小、设备不足，公司产能长期处于紧平衡状态，难以满足新能源、智能电网等领域快速增长的产品需求。2023年，公司开始筹备电子元器件生产项目，通过建设高标准厂房和立体仓库，以数字化、智能化重塑生产全链条，打造智慧工厂，力求扩大产能、提升产品品质。设备的智能化升级是项目的一大亮点。全自动绕线机1000台、纳米晶自动卷绕机600台……穿梭在生产线的各个环节，周恩勇对各种智能设备如数家珍。

四 | “过去依赖人工操作，效率低、成本高。现在公司引进了先进设备，不仅大幅提高成品率，还实现了降本增效。”周恩勇说。来到一台视觉检测机前，记者看到，一名员工将一枚磁芯放入检测台，机器自动完成质量检测，并分拣出合格品和次品，又快又准。

五 | “这是我们自主研发的智能检测机，检测效率较传统人工检测提高了数倍。”周恩勇告诉记者，公司专门成立了设备研发部门，根据生产需求，自主研制智能设备，不断提高生产线的智慧化水平。

六 | 除了升级设备，公司还积极引入多套数字化管理系统，力求实现生产全流程的无人化、智能化管控。在铁芯真空热处理车间里，10多台真空热处理炉高效运行。在中控室，一名员工正通过电脑上的横磁炉自动控制系统，远程监控炉内温度、气压等。

七 | 周恩勇指着屏幕介绍，他们在系统上设定好工艺参数，炉子就能自动执行命令。一旦出现异常，系统自动发出预警，及时提醒工作人员到场干预。

八 | 在周恩勇看来，提高产品核心竞争力是企业的立身之本。厂区内，一款刚出炉的纳米晶互感器格外吸睛。

九 | 该产品由公司自主研发，小巧但功能齐全。据统计，这款产品月均销售量达150万只，处于行业领先地位。

十 | “多数生产互感器的厂家选择购买铁芯部件。而我们选择自产铁芯，采用国内先进的铁芯生产工艺，打造从母合金冶炼、带材制作到互感器制造的全产业链条。”周恩勇表示。项目的稳步推进，不仅是企业技术迭代、产能提升的重要举措，更是当地持续优化营商环境的生动实践。从立项到开工，青县经济开发区组成服务专班，为项目提供了“一站式”全流程帮办代办和跟踪服务，将投产预期时间缩短了三分之二。“每个环节都有专人主动对接和上门服务，我们可以安心搞建设、搞研发。”周恩勇说。市场需求与营商环境的双重驱动，让公司对项目未来发展充满信心。“立足‘十五五’开局之年新起点，我们将继续坚持技术引领，加速产品迭代升级，深耕国内外市场，稳步提升产品竞争力和市场占有率，为加快推动新一代电子信息产业高质量发展注入新动能。

十一 | ”周恩勇表示。（日报记者 解楚楚）。
