Vehicle door latch, in which the catch comprises a casing made of sound-proofing material, the casing containing a buffer pocket, situated behind the primary position in clockwise direction and the buffer pocket being stretched around up to the area of the primary position, forming an overtravel stop cooperating with the pawl. The method can include a wireless communication device detecting a stall condition resulting from a transmission channel change. The connector can also include a second arm, connected to the support portion, and defining a second arm channel, the second arm being apart from the first arm. The holdable registers can prevent that the inputs of unused functional units change, which would result in unnecessary power dissipation. The opening provides a liquid path to the rear face of the vibratable membrane. Among the factors considered in the optimization are the characteristics of the originating source and the network path.
