Abstract: A system and method for producing an image include a plurality of sensors detecting light from a subject being imaged, each sensor generating an associated video signal indicative of its detected light, each video signal comprising a predefined time interval. A decoder receives the video signals from their associated sensors, detects the predefined time intervals of the received video signals, generates a synchronization signal, and transmits the synchronization signal to each sensor during the predefined time interval of its associated video signal.

Abstract: An image sensing systems supports independently setting sensor parameters in two or more different regions of interest. In one implementation resolution, exposure time, and gain are independently selectable in each region of interest. Independently setting exposure time and gain in different regions of interest improves image recognition when there are large differences in the illumination of objects within an image. Independently setting resolution permits the resolution to be selectively increased in regions of interest requiring high resolution in order to reduce the pixel data bandwidth and processing requirements.

Abstract: An image sensor includes near-infrared cut filters formed over an array of photosensitive elements in a predetermined pattern. The near-infrared cut filters may be formed over one half of a photosensitive element in a split pixel arrangement, over one half the photosensitive elements in the array, over every other photosensitive element in the array, and/or in a checkerboard pattern.

Abstract: Sensor system for sensing pressure applied to a seat by an occupant of the seat and for controlling deployment of an airbag which includes a bladder defining a chamber and which is adapted to be arranged in a seat portion of the seat, and a pressure sensor for measuring a pressure in the chamber. Deployment of the airbag is controlled based at least in part on the pressure in the chamber measured by the pressure sensor. A control module may be provided to control deployment of the airbag so that when the pressure sensor generates a signal based on the measured pressure in the chamber and provides the signal to the control module, the control module controls deployment of the airbag based on the signal.

Abstract: Method for determining weight of an occupying item of a seat in a vehicle having a seat cushion assembly and a seat back assembly defining a contact surface adapted to be in contact with the occupying item of the seat in which a support structure is arranged underneath the seat cushion assembly to support the seat on a substrate in the vehicle. The support structure transfers a force exerted by the occupying item on the support structure to the substrate. At least one strain measuring transducer is mounted at a respective location on the support structure to provide a measurement of the strain in the support structure at the location at which it is mounted. The weight of the occupying item of the seat is determined based on the strain in the support structure measured by the strain measuring transducer(s).

Abstract: Method and system for obtaining and optionally utilizing information about an occupant of a vehicle includes a weight sensor system arranged in connection with a bottom portion of a seat on which the occupant will be seated to provide data about weight of an occupant, and a spatial sensor system which monitors a space above the seat in which the occupant would be situated if seated in the seat to provide data about occupancy of the space above the seat. Information about the occupant is determined based on data provided by the weight sensor system and the spatial sensor system. The weight sensor system is a bladder arranged in the bottom portion or at least one strain gage mounted on structural members of the seat.

Abstract: Method for developing and adapting a system for determining the location of an object in a passenger compartment of a vehicle using a variety of transducers and pattern recognition technologies and techniques that applies to any combination of transducers that provide information about vehicle occupancy. These include weight sensors, capacitive sensors, inductive sensors, ultrasonic, optic, infrared, radar among others. The adaptation process begins with a selection of candidate transducers for a particular vehicle model based on, e.g., cost, vehicle interior passenger compartment geometry, desired accuracy and reliability, vehicle aesthetics, vehicle manufacturer preferences. Once a candidate set of transducers is selected, these transducers are mounted in the test vehicle and the vehicle is subjected to an extensive data collection process wherein various objects are placed in the vehicle at various locations and various databases are collected.

Abstract: System for determining the occupancy of a seat in a vehicle using pattern recognition technologies and techniques that apply to any combination of transducers that provide information about seat occupancy, for example, weight sensors, capacitive sensors, inductive sensors, ultrasonic, optical, electromagnetic, motion, infrared and radar sensors. A processor is coupled to the transducers for receiving data therefrom and processes the data to obtain an output indicative of the seat's current occupancy state. A combination neural network is resident in the processor and is created from data sets, each representing a different occupancy state of the seat and being formed from data from the transducers while the seat is in that occupancy state. The combination neural network produces the output indicative of the current occupancy state of the seat upon inputting a data set representing the current occupancy state of the seat and being formed from data from the transducers.
