Abstract: Example embodiments described in this disclosure are generally directed to systems and methods for preventing vehicle mishaps. In an example method, a vehicle receives an alert signal from a personal transportation device. A driver of the vehicle may be made aware of the alert by a sound that is produced through a speaker system of the vehicle (for example, a ringing sound produced by a bicycle bell or a beep of a motorcycle horn). In some cases, an intensity and/or a directionality of the sound produced through the speaker system may provide location and/or distance information of the personal transportation device with respect to the vehicle. The vehicle may transmit an acknowledge signal to the personal transportation device. A rider of the personal transportation device may be informed of the acknowledgement via an audio announcement through a speaker mounted on the personal transportation device.

Abstract: A system includes a computer programmed to, in response to receiving a parking transmission from a parked vehicle, transmit a parking authorization credential to the parked vehicle for rebroadcast from the parked vehicle, the parking authorization credential confirming that the parked vehicle is authorized for a parking location.

Abstract: Embodiments include a vehicle comprising an audio system configured to create a plurality of audio zones within a vehicle cabin, and at least one display communicatively coupled to the audio system. The display is configured to display a separate user interface for each audio zone. Each user interface comprises an engine sound control and a cabin noise control for adjusting an audio output provided to the corresponding audio zone. Embodiments also include a method of providing user-controlled sound isolation in a plurality of audio zones within a vehicle. The method comprises presenting, for each audio zone, a user interface including an engine sound control and a cabin noise control, and generating an audio output for each audio zone based on a first value received from the engine sound control and a second value received from the cabin noise control of the corresponding user interface.

Abstract: Exemplary embodiments of the invention provide a reference harmonic oscillator integrated circuit having three or more terminals, with systems and methods for calibrating the harmonic oscillator to a selected first frequency using a limited number of terminals. An exemplary apparatus comprises: a reference harmonic oscillator, a first terminal to receive a supply voltage, a second terminal to receive a ground potential, a third terminal to provide an output signal having an output frequency, and may also include a fourth terminal. One of the first, second, third or fourth terminals is further adapted for input of a calibration of the first frequency. The exemplary apparatus may enter calibration and testing modes in response to various commands such as a calibration mode signal, and may also be configured through one of the terminals for output frequency selection, spread-spectrum output, and output voltage levels.
