MODULATION TRANSFER FUNCTION EVALUATION FOR RED/CLEAR FILTERED OPTICAL DEVICES

ZF ACTIVE SAFETY AND ELEC...

1. A system for evaluating a modulation transfer function (MTF) of a device under test comprising a red/clear (RCCC) color filter, the system comprising:a pattern source that provides a pattern suitable for use in the evaluating the MTF via a slanted method;
the device under test, which images the pattern to provide an image comprising a plurality of filtered pixels, each having an associated brightness value, and a plurality of unfiltered pixels, each having an associated brightness value; and
an image analysis system that determines, for each of a plurality of filtered pixels, an axis of a plurality of axes having a lowest curvature, wherein a first axis of the plurality of axes is not orthogonal to a second axis of the plurality of axes, generating an interpolated image having a new brightness value for each of the plurality of filtered pixels as a function of respective brightness values for a set of unfiltered pixels selected from a first-order Moore neighborhood of the pixel, the set of pixels being selected along the axis having the lowest curvature, and determines the modulation transfer function from the interpolated image.

BALL NUT ASSEMBLY FOR A POWER STEERING ASSEMBLY OF A VEHICLE

ZF Active Safety and Elec...

1. A power steering assembly comprising:a housing;
a ball nut assembly supported on the housing and having a ball nut axis;
a first surface between the housing and the ball nut assembly;
a second surface of the ball nut assembly, wherein the second surface rotates on the first surface such that the ball nut assembly rotates relative to the housing on a rotation axis that is transverse to the ball nut axis; and
first and second stop surfaces between which the second surface rotates and that limit rotational movement of the ball nut assembly relative to the housing.

EXTERNAL DAMPING OF POWER STEERING FOR A VEHICLE

ZF Active Safety and Elec...

1. A power steering assembly comprising:a steering linkage in a steering housing;
a power source effecting movement of the steering linkage;
a damper;
a first connection between the damper and the steering linkage; and
a second connection between the damper and a ground surface comprising the steering housing, wherein the steering linkage is moveable relative to the ground surface.

VEHICLE SAFETY SYSTEM WITH SMART DETECTION SENSORS

ZF ACTIVE SAFETY AND ELEC...

1. A state detection sensor for a vehicle including a seat and a seatbelt associated with the seat, comprising:a housing configured to be mounted to a vehicle component,
the vehicle component being one of the seat and the seatbelt buckle;
a position sensing component mounted in the housing and being configured to
provide position data in response to detecting the presence or
position of structure of the vehicle component relative to the sensor;
an analog input component mounted in the housing and being configured to
receive an analog signal from an external analog sensor,
wherein the analog sensor is configured to be mounted to one of
the seat and
seatbelt buckle;
an analog to digital converter (ADC) component configured to receive the analog signal from the analog input component, digitize the analog signal, and
provide digitized external analog sensor data; and
a component configured to communicate the position data and the external analog sensor data via a serial bus,
wherein the state detection sensor comprises
a vehicle seat sensor,
wherein the position sensing component comprises a seat track position sensor.
