Patent number: 11584351Abstract: A parking release monitoring device for an automatic transmission vehicle is proposed. The device includes: a receiver sensing an output signal of a shift lever; a determiner determining a target gear stage in accordance with the output signal of the shift lever; a driver transmitting a control signal to a parking solenoid to engage a parking sprag and applying a driving current to a clutch control solenoid to engage a clutch and prevent rolling of the vehicle when the determined target gear stage is a P-gear stage; and a detector measuring the intensity of the driving current applied to the clutch control solenoid, in which the determiner receives intensity information of the driving current applied to the clutch control solenoid from the detector and compares the received intensity information of the driving current with the output signal of the shift lever, thereby determining whether parking release has occurred.Type: GrantFiled: December 10, 2020Date of Patent: February 21, 2023Assignee: Hyundai Kefico CorporationInventors: Chang Kyu Shin, Ji Young Jung

Patent number: 7754372Abstract: A lithium secondary battery having a cap assembly including a cap plate, an insulation plate and a terminal plate. The insulation plate and the terminal plate each have a predetermined vent hole corresponding to a safety vent formed on the cap plate so that if the secondary battery is dropped, an electrolyte passes through the vent-holes and undergoes a pressure reduction, thereby preventing fracture of a safety vent by the electrolyte while allowing gas to be exhausted upon battery overcharge, full discharge or by overheating.Type: GrantFiled: March 16, 2006Date of Patent: July 13, 2010Assignee: Samsung SDI Co., Ltd.Inventors: Teak Hyen Kwon, Chang Kyu Shin, Hoon Yim
