Abstract: In a method for data transmission in which the binary original data (D0, . . . , Dm) is transferred from a transmitter to a unit of a receiver (1), selected preferably by means of a binary base address (A0, . . . , An), preferably to a register (80, . . . , 87), where the original data (D0, . . . , Dm) and preferably also the base address (A0, . . . , An) are transmitted through one or several data lines, the inverted original data (inversion data) (D0′, . . . , Dm′) and preferably also the complementary base address (complementary address) (A0′, . . . , An′, Ak) are transmitted by the transmitter. The transmitted inversion data (D0′, . . . , Dm′) and preferably the transmitted complementary address (A0′, . . . , An′, Ak) are inverted in the receiver, the transmitted base address (A0, . . . , An) and the transmitted original data (D0, . . . , Dm) are compared with the inverted complementary address (A0′, . . .

Abstract: An optical transmitting and receiving device with light-conducting receiver, which are arranged inside the housing, in front of a light-permeable cover between a transmitting unit and a receiving unit, so that the share of light reflected at the light-permeable cover of the transmitting unit is conducted to the receiving unit, thus making it possible to detect the operational readiness of the transmitting unit as well as the degree of soiling of the light-permeable cover.

Abstract: A vehicle occupant sensing system includes a laser array that generates three beams. A first beam is directed toward an upper body zone, a second beam is directed toward a middle body zone, and a third beam is directed toward a lower body zone. A first sensor assembly receives reflection beams from the upper body zone and generates a first signal that represents a proportional amount of an occupant present in the upper body zone. A second sensor assembly receives reflection beams from the middle body zone and generates a second signal that represents a proportional amount of the occupant present in the middle body zone. A third sensor assembly receives reflection beams from the lower body zone and generates a third signal that represents a proportional amount of the occupant present in the lower body zone. The laser array and the first, second, and third sensor assemblies are all mounted within a common housing that is mounted to a vehicle structure such as an A-pillar or rear view mirror.
