Patent number: 9689657Abstract: The disclosure relates to a method of detecting an object using a detection signal supplied by a proximity sensor. The method comprises the steps of generating a reference signal by filtering the value of the detection signal, defining a first detection threshold, and going from an object non-detecting state to an object detecting state when the value of the detection signal becomes greater than the first detection threshold. When the value of the detection signal becomes greater than the first detection threshold, the value of the reference signal is readjusted in a manner such that the value of the detection signal again becomes less than or respectively greater than, the first detection threshold.Type: GrantFiled: August 3, 2011Date of Patent: June 27, 2017Assignee: STMicroelectronics (Rousset) SASInventors: Maxime Teissier, Cyril Troise

Patent number: 9097774Abstract: Internal shorts and other failures in lithium-ion battery cells may be detected during balancing of the battery cells. A counter may be used to detect when a battery cell is behaving differently than other battery cells by balancing more or less frequently. The counter may increment each time a battery cell is balanced to the other battery cells. A misbehaving battery cell may be flagged, when the counter exceeds a threshold value, for safety checks before an overheating event occurs. This misbehaving battery cell may be faulty due to an internal short. If the faulty battery cell is not corrected by replacement with a different battery cell or corrected by a user resetting the counter, the misbehaving battery cell may be disconnected to prevent the overheating event.Type: GrantFiled: July 14, 2011Date of Patent: August 4, 2015Assignee: SOUTHWEST ELECTRONIC ENERGY CORPORATIONInventors: David A.
