Publication number: 20180341106Abstract: The lighting of a person via incident light radiation is controlled to address dazzling. The light radiation originates from a source of light and passes through a medium of variable and controllable opacity. The position of the source of light relative to the person can vary. A zone of the eyes of the person and a position of the zone of the eyes relative to the medium is detected. A incidence of dazzling of the zone of the eyes is detected. In response to the detection, the direction of incidence of the light radiation is determined. From this determination, from the position of the zone of the eyes, a region of said medium is identified that has a projection on the face of the person which includes said zone of the eyes. The opacity of the region of the medium is then modified in a controlled manner to preclude dazzling.Type: ApplicationFiled: May 21, 2018Publication date: November 29, 2018Applicant: STMicroelectronics (Grand Ouest) SASInventor: Vincent ABRIOU

Patent number: 10141246Abstract: The present disclosure is directed to a leadframe package having a side solder ball contact and methods of manufacturing the same. A plurality of solder balls are coupled to recesses in a leadframe before encapsulation and singulation. After singulation, a portion of each solder ball is exposed on sidewalls of the package. This ensures that the sidewalls of the leads are solder wettable, which allows for the formation of stronger joints when the package is coupled to a substrate. This increased adhesion reduces resistance at the joints and also mitigates the effects of expansion of the components in the package such that delamination is less likely to occur. As a result, packages with a side solder ball contact have increased life cycle expectancies.Type: GrantFiled: April 12, 2018Date of Patent: November 27, 2018Assignee: STMicroelectronics, Inc.Inventors: Jefferson Talledo, Tito Mangaoang
