Encoder device and method of determining a kinematic value

An encoder device for determining a kinematic value of the movement of a first object relative to a second object is provided, wherein the encoder device comprises a standard associated with the first object and at least one scanning unit associated with the second object for producing at least one scanning signal by detection of the standard and a control and evaluation unit that is configured to determine the kinematic value from the scanning signal. The control and evaluation unit is here further configured to determine the kinematic value by an evaluation of the scanning signal using a method of machine learning, with the evaluation being trained with a plurality of scanning signals and associated kinematic values.

Measurements incorporating brake light detection

Systems, methods, and non-transitory computer readable media may be configured to calibrate sensor measurements based on detection of brake light. Acceleration information of a first vehicle may be obtained. The acceleration information may define an acceleration probability distribution of the first vehicle. Image information may be obtained. The image information may define an image of the first vehicle. Whether a brake light of the first vehicle is on or off may be determined based on the image of the first vehicle. Based on a determination that the brake light of the first vehicle is on, a calibrated acceleration probability distribution of the first vehicle may be generated based on the acceleration probability distribution of the first vehicle and a braking-calibration curve.

Finger-Mounted Device With Sensors and Haptics

A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

VEHICLE NOTIFICATION APPARATUS

A vehicle notification apparatus recognizes an object of driving over on a road on which a host vehicle travels based on a detection result by a front sensor of the host vehicle, determines whether the object of driving over flies backwards based on a detection result by a rear sensor of the host vehicle when the object of driving over is recognized, and notifies a following vehicle of projectile information corresponding to the flight of the object of driving over when it is determined that the object of driving over flies backwards.

Wheel position detector and tire inflation pressure detector having the same

A wheel position detector for a vehicle includes: a transmitter at each wheel having a first control portion for generating and transmitting a frame with specific identification information; and a receiver at a vehicle body receiving the frame from one wheel and having a second control portion for performing wheel position detection; and a wheel speed sensor for detecting a tooth of a gear. The second control portion: acquires gear information indicating a tooth position; corrects the tooth position based on a time difference between acquiring of the gear information and receiving time of the frame; and specifies the one wheel based on the tooth position at reception time.

Wheel position detector and tire inflation pressure detector having the same

In a wheel position detector for a vehicle, a transmitter on each wheel repeatedly transmits a data frame containing identification information when an angle of the transmitter reaches a transmission angle. A receiver for receiving the frame is mounted on a body of a vehicle and performs wheel position detection based on the frame to specify a target wheel from which the frame is transmitted. The receiver acquires a tooth position of a gear rotating with a corresponding wheel when receiving the frame and sets a variation allowable range based on the tooth position. The receiver specifies the target wheel by determining whether the tooth position falls within the variation allowable range. The transmitter changes the transmission angle at a predetermined time interval.

Wheel position detecting device and tire pressure detecting apparatus having the same

In a wheel position detecting device, a transmission angular position of a transmitter to transmit a frame from the transmitter to a receiver is changed by a predetermined angle each time the transmitter transmits the frame. A receiver acquires gear information indicating a tooth position of a gear rotating in association with a corresponding wheel, based on a detection signal of a wheel speed sensor. The receiver specifies to which wheels the transmitter is integrated, based on the tooth position of the gear at a reception timing of the frame.
