A head up display arrangement for a motor vehicle includes an image source providing illuminated images. At least one mirror is positioned to provide a first reflection of the illuminated images. A windshield is positioned to receive the first reflection and provide a second reflection of the illuminated image such that the second reflection is visible to a driver of the vehicle who has at least one eye within an eyebox defined by the second reflection. An image capturing device captures images of a head of a driver of the motor vehicle. An electronic processor adjusts, based on the captured images of the driver's head, the illuminated images and/or a position of the at least one mirror.

A method of operating a video system includes receiving an image captured by use of a fisheye lens. The image is divided into a plurality of horizontal image lines. A respective fraction of each of the horizontal image lines is sampled with a different respective sampling frequency. Each sampling frequency is inversely related to a size of the sampled fraction. The size of the sampled fraction increases with each horizontal image line in a progression from a top of the image to a bottom of the image.

Rectifier circuit for monitoring DC offset of a single-supply audio power amplifier

A method of operating an audio system in an automobile includes identifying a user of the audio system. An audio recording playing on the audio system is identified. An audio setting entered into the audio system by the identified user while the audio recording is being played by the audio system is sensed. The sensed audio setting is stored in memory in association with the identified user and the identified audio recording. The audio recording is retrieved from memory with the sensed audio setting being embedded in the retrieved audio recording as a watermark signal. The retrieved audio recording is played on the audio system with the embedded sensed audio setting being automatically implemented by the audio system during the playing.

A method of modulating an infrared headphone interface signal includes providing a first audio signal having an analog audio value. A memory is provided having a plurality of locations and containing digital phase offset values. A clock signal having a clock frequency is provided. A second audio signal having a center carrier frequency that deviates with the analog audio value of the first audio signal is provided. An instantaneous value of the center carrier frequency is determined. The clock frequency is divided by the instantaneous carrier frequency value to calculate a number of samples per cycle. A number of location addresses in the memory is divided by the number of samples per cycle to calculate a memory access interval. The memory is accessed at addresses separated by the memory access interval. The digital phase offset values at the accessed memory addresses are used to reproduce the first audio signal.

Digital technique for FM modulation of infrared headphone interface signals

A method of controlling a head for a recording medium includes determining that the head is in an inoperative state, and activating a damping arrangement in response to the determination that the head is inoperative. A movement of the head while the head is inoperative is sensed. The damping arrangement is used in response to the sensing step to exert a force upon the head to thereby damp the movement, a magnitude of the force being dependent upon a parameter of the movement.
