Patent number: 11961775Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.Type: GrantFiled: November 8, 2022Date of Patent: April 16, 2024Assignee: Amkor Technology Singapore Holding Pte.

Patent number: 11926310Abstract: Controlling a speed limit includes determining a virtual vehicle speed as being a lower one of a vehicle speed and a target limit speed, determining a virtual APS value as being a larger one of a first APS value and a second APS value, transitioning to a second mode at a point in time at which an actual APS value and the second APS value become different, when it is expected to transition to the second mode, among a first mode for sustaining a SOC of a battery at the target limit speed and the second mode for depleting the SOC, and determining a transmission gear position by applying the determined virtual vehicle speed and the determined virtual APS value to one of a first shifting pattern and a second shifting pattern.Type: GrantFiled: September 28, 2020Date of Patent: March 12, 2024Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Hui Un Son, Sang Joon Kim, Kyu Hwan Jo, Sung Bae Jeon, Sung Hoon Yu, Joo Young Kim, Jin Kyeom Cho

Publication number: 20240067079Abstract: A brake lamp control method of a vehicle is provided. The method includes determining whether a deceleration of the vehicle based on regenerative brake through the electric motor is present in a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp. When the deceleration of the vehicle is present in the hysteresis period, the method includes determining a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period. In response to determining that the brake lamp is turned on or off for a reason except for the regenerative brake before the deceleration of the vehicle enters the hysteresis period, a request for turning on the brake lamp is set or reset based on the regenerative brake in response to the determined state of the brake lamp.Type: ApplicationFiled: November 2, 2023Publication date: February 29, 2024Inventors: Hui Un Son, Sang Joon Kim, Kyu Hwan Jo, Sung Bae Jeon, Sung Hoon Yu, Joo Young Kim, Jin Kyeom Cho
