Abstract: A system and method for recording videos of road views of a moving motor vehicle direction of travel, wirelessly uploading the recorded images to a remote server/cloud structure, wirelessly transmitting the recorded video images for display concurrent with the recording. The road view images can be displayed in real time. Also extracting and processing data from the images and displaying such data to a separate vehicle driver. Data may include images of other vehicles, vehicle speeds and distances, objects and object identification and road conditions including weather. Also extracting and processing data from recorded images of camera view of inside the vehicle cabin. System of incentivizing drivers to participate in the vehicle and traffic monitoring, driver performance and distraction detection, voice recognition for hands free operation, automatic vanishing point calibration, video chat/video streaming between vehicles, merchant advertising by location.

Abstract: A traffic and road condition monitoring system utilizing a vehicle mounted camera recording images of traffic, road conditions ahead of the vehicle wherein the recorded images are uploaded to a component that can distribute the images in real time to remote display components, a transmission component that transmits the image to a remote server in real time as the image is recorded, an image storage component operable with the server, a transmission component operable with the server to transmit real time or stored images to a remote display monitor, and a data processor component to compute distance or speed of objects within the image. The remote display monitor may be positioned in a separate vehicle such as a following vehicle. The traffic images may be shared directly between vehicles in a peer to peer network.

Abstract: A voltage controlled oscillator frequency tuner has a first differential switch set and a second differential switch set. Each differential switch set has one pair of switch transistors controlling current to one pair of capacitors. The activating means activates only one set or no sets, and can differential switch switch from the first differential switch set to the second differential switch set. Differential switch switching provides a capacitance difference proportional to the capacitance difference of the first differential switch set capacitor pair and the second differential switch set capacitor pair.

Abstract: A compensated fractional-N synthesizer has a voltage controlled oscillator providing a frequency output signal. The frequency divider divides the frequency output signal. It generates a frequency divider output divided signal. A frequency divider receives controlling signal from an adder receiving a fractional signal from a sigma-delta modulator and an independent integer number signal. A phase frequency detector compares a reference frequency signal with a frequency divider output divided signal outputting a phase frequency detector output to a charge pump. A loop filter for filtering a current provides filtered current to a voltage controlled oscillator. A charge pump provides current and a charge pump compensation means has a plurality of switch transistors providing an output signal to said charge pump. The charge pump compensation means receives the fractional signal from the sigma-delta modulator.

Abstract: A BFSK demodulator comprises a three-channel frequency-to-voltage converter, an information signal inputting the first-channel frequency-to-voltage converter, a converted information signal inputting the second-channel frequency-to-voltage converter, wherein outputs of first and second channel frequency-to-voltage converter are connected with a capacitor, a output voltage signal produced by the first and second frequency-to-voltage converters and the capacitor, inputting into a positive terminal of the comparator after high frequency noise filtering through a first low-pass filter, a carrier signal inputs into the third-channel frequency-to-voltage converter; and an output from the third-channel frequency-to-voltage converter connected to a capacitor; and a reference voltage signal is produced after high frequency noise filtering through a second low-pass filter, producing a demodulated signal after comparing the information voltage signal with the reference voltage.
