The invention relates to a connector element of an electrical connector, comprising a contact carrier that is provided with one or more electrical contacts, an actuation sleeve which surrounds the contact carrier, and a threaded engaging part that is provided with one or more engaging thread projections which are to penetrate into a mating thread of a mating connector element. A control difference is determined from a difference between a predefined fuel pressure and a detected fuel pressure. In response to determining that the count exceeds the prior count, a bit of the first group of data bits that has the particular bit value and that corresponds to a same memory cell as a corrected data bit of a second group of data bits is identified. The luminaire described herein provides a light source with enhanced thermal dissipation features in an aesthetically pleasing package. Each sensor device can be switched between a master mode, in which the device is operable to transmit events derived from a signal from an object, and a slave mode, in which the device is responsive to such events from another sensor device for processing its own signal in order to determine the time delay between receipt of the signals by the sensors of the respective devices.
