Abstract: A battery management system is a battery management system managing a battery device loaded in a vehicle. The battery management system includes: a sensor configured to measure an ON time of a battery module included in the battery device, the sensor being included in the battery device; a communication device configured to send the ON time measured by the sensor to a management device, the management device managing the ON time of the battery module and receive a reference value from the management device; and a circuitry configured to judge whether the battery module has been used outside management of the management device, based on the ON time measured by the sensor and the reference value, wherein the communication device also sends a judging result determined by the circuitry to the management device.

Abstract: An airbag assembly for a motor vehicle includes an inflatable airbag, a tether, and at least one guide member. The tether controls deployment of the inflatable airbag. The tether has a fixed length between a first end and a second end. The at least one guide member slidably receives the tether such that the tether has a first adjustable length portion between the first end and the at least one guide member and the tether has a second adjustable length portion between the second end and the at least one guide member.

Abstract: Gas guides or airbag assemblies including gas guides are disclosed. The gas guides can direct inflation gas within an inflatable cushion. The gas guides can include a forward opening that delivers inflation gas to a forward portion of an inflatable cushion and a rearward opening that delivers inflation gas to a rearward portion of an inflatable cushion. The gas guides can further include a downward opening that delivers inflation gas downward to a lower portion of an inflatable cushion. The area of the downward opening can be greater than the areas of the forward opening or the rearward opening such that a greater portion of the inflation gas is directed downward into the inflatable cushion.
