  • Patent number: 10643377
    Abstract: A method for mapping and planning a parcel or garden may include receiving information indicative of position data of a robotic vehicle transiting a parcel and corresponding image data captured by the robotic vehicle at one or more locations on the parcel. The method may further include generating a base-map of the parcel based on the information received and providing a graphical representation of the parcel based on the base-map. The method may further include enabling an operator to generate a modified-map.

  • Patent number: 10310510
    Abstract: A robotic vehicle may be configured to incorporate multiple sensors to make the robotic vehicle capable of detecting grass by measuring edge data and/or frequency data. In this regard, in some cases, the robotic vehicle may include an onboard positioning module, a detection module, and a mapping module that may work together to give the robotic vehicle a comprehensive understanding of its current location and of the features or objects located in its environment. Moreover, the robotic vehicle may include sensors that enable the modules to collect and process data that can be used to identify grass on a parcel on which the robotic vehicle operates.

  • Publication number: 20180167250
    Abstract: Systems and methods are provided for broadcasting a for broadcasting a modulated signal. A plurality of peaks is detected within a waveform envelope signal of the modulated signal. For each of the plurality of peaks, a pulse having substantial spectral content that is outside of a passband of a high power filter is constructed. The constructed pulse for each peak is subtracted from its associated peak to provide a peak-reduced signal. The peak-reduced signal is amplified at a power amplifier to provide an amplified signal. The amplified signal is filtered at the high power filter to provide a filtered signal. The filtered signal is broadcast at an associated antenna.

  • Patent number: 8274921
    Abstract: A system communicates data and includes a transmitter for transmitting a communications signal that carries communications data. It includes an efficient modulator for approximating the frequencies of sine/cosine basis waveforms using complex exponential functions and adding and subtracting the complex exponential functions to generate an Orthogonal Frequency Division Multiplexed (OFDM) communications signal as a plurality of N data subcarriers that carry communications data as data symbols. A receiver receives the OFDM communications signal and includes a demodulation circuit for demodulating the OFDM communications signal using logical shifts of multiples +/?2p based on complex exponential functions corresponding to sine/cosine basis waveform approximations to extract amplitude and phase values from a plurality of N data subcarriers as data symbols within the OFDM communications signal.

  • Patent number: 8238454
    Abstract: A communications device includes a signal input that receives an orthogonal frequency division multiplexed (OFDM) communications signal. A demodulator is connected to the signal input for receiving the OFDM communications signal and demodulating the OFDM communication signal. It includes at least one memory element for storing the at least one sine/cosine basis waveform approximation as complex exponential functions. A logic circuit performs logical shifts in additions and multiples of +/?2n and extracts amplitude and phase values from a plurality of N data subcarriers within the OFDM communications signal. The demodulator includes efficient implementation of the FFT for use as an OFDM demodulator where the complex exponentials are approximated by multi-level complex sinusoids and optionally oversampled to increase SNR of the FFT output.

  • Patent number: 7648090
    Abstract: A disc housing intended for refiners with refining discs rotating in opposed directions relative to each other is disclosed for mechanically disintegrating and working fibrous material. The disc housing surrounds the refining discs in an air-tight manner, and is provided with an outlet for the worked fibrous material. The inside of the disc housing along its periphery is formed with a channel, which, as seen in the circumferential direction, has a continuously increasing radius, which increases all the way to the outlet, which is located tangentially as a direct continuation of the channel.
