Abstract: A window system for a passenger compartment of a vehicle includes a window including an inner transparent layer, an outer transparent layer and a pixelated layer interposed therebetween. The pixelated layer includes a two-dimensional array of electrochromic cells and an electrode array that is electrically connected to the electrochromic cells. A controller determines, via an incident light monitoring subsystem, a field of view of a passenger and determines an intensity of incident light in relation to the field of view of the passenger. The controller is disposed to command a passenger compartment incident light management subsystem to activate selected electrochromic cells in the transparent window based upon the intensity of the incident light in relation to the field of view of the passenger.

Abstract: A method for controlling an inflatable airbag system in a motor vehicle having a seatbelt includes detecting a position of a vehicle occupant relative to an airbag suppression zone (ASZ). Electronic input signals are received from a sensor suite, including an occupant position signal and a seatbelt usage status signal. A restraint capacity setting of the airbag is adjusted in response to the electronic input signals such that corresponding restraint activation logic is executed by the controller based on whether the occupant is belted or unbelted. Different ASZs may be used for belted and unbelted occupants. A motor vehicle includes a vehicle body defining a vehicle interior, an airbag, a seatbelt, a sensor suite for detecting a position of an occupant relative to the ASZ, and a controller operable for controlling a restraint capacity setting and location of the ASZ in accordance with the method.

Abstract: A method for operating an automobile vehicle pedestrian sensing system includes: embedding multiple piezoelectric sensors in a vehicle bumper fascia, each generating a voltage in response to an impact of an object with the fascia; retrieving multiple threshold values from a memory, each assigned to one of the sensors; reading the voltage from each of the sensors; grouping individual sensors into multiple different logic circuits, each including at least two of the sensors; determining for each sensor in each of the logic circuits if the voltage is greater than the assigned threshold value; creating a positive signal following any one of the logic circuits when the voltage is determined to be greater than the assigned threshold value for the sensors grouped into the one of the logic circuits; and generating a hood deployment system deployment signal when the positive signal is output from all of the logic circuits.
