  • Patent number: 11362700
    Abstract: An apparatus comprises a frequency accumulator to produce a frequency ramp, and a symbol modulator to receive symbols and to add to the frequency ramp frequency offsets representative of the symbols, to produce a modulated frequency ramp for a modulated chirp. The apparatus includes a spreading factor controller to control a roll-over rate of the modulated frequency ramp responsive to spreading factor and frequency bandwidth control signals, to control a spreading factor and a frequency bandwidth of the modulated chirp. The apparatus includes a center frequency controller to control a center frequency of the modulated frequency ramp responsive to a center frequency control signal. The apparatus includes a phase accumulator to accumulate frequency samples of the modulated frequency ramp to produce phase samples corresponding to the modulated chirp, and a vector rotator to rotate the phase samples based on an input vector to produce a modulated chirp.

  • Publication number: 20220006825
    Abstract: Embodiments presented herein describe techniques for generating a linguistic model of input data obtained from a data source (e.g., a video camera). According to one embodiment of the present disclosure, a sequence of symbols is generated based on an ordered stream of normalized vectors generated from the input data. A dictionary of words is generated from combinations of the ordered sequence of symbols based on a frequency at which combinations of symbols appear in the ordered sequence of symbols. A plurality of phrases is generated based an ordered sequence of words from the dictionary observed in the ordered sequence of symbols based on a frequency by which combinations of words in ordered sequence of words appear relative to one another.

  • Patent number: 11190277
    Abstract: Upon receiving a communications signal conveying symbols at a symbol period T, a receiver applies filter coefficients to a digital representation of the communications signal, thereby generating filtered signals characterized by a substantially raised cosine shape in the frequency domain with a roll-off factor ?, where components of the filtered signals correspond to angular frequencies ? = - ? ? ( 1 + ? ) T ? … - ? ? ( 1 - ? ) T , + ? ? ( 1 - ? ) T ? … + ? ? ( 1 + ? ) T . The receiver calculates first-order components from a first phase derivative of the components at a first differential distance, second-order components from a second phase derivative of the first-order components at a second differential distance, and composite second-order components from an average of the second-order components over multiple time intervals.

  • Patent number: 11132431
    Abstract: A password input and identification system includes a one-button password input component and a controller. The one-button password input component generates a series of trigger signals in response to a series of triggers that correspond to a series of user-input digits. The controller determines a value of each of the user-input digits by counting a number of the trigger signal(s) that correspond(s) to the user-input digit to serve as the value of the user-input digit. The controller compares the user-input digits with the predetermined password after the input of the user-input digits is finished, and performs a predetermined action when the user-input digits match the predetermined password.

  • Patent number: 10419137
    Abstract: In a digital communication system there is provided a method for OFDM channel estimation that jointly considers the effects of coarse timing error and multipath propagation. The method uses an iterative channel estimation technique, which considers the practical scenario of fractional timing error and non-sample space echo delays. The method does not require channel state information such as second-order statistic of the channel impulse responses or the noise power. Moreover, timing error can be conveniently obtained with the proposed technique. Simulation shows that, when comparing OFDM channel estimation techniques under DOCSIS 3.1 realistic channel conditions, the proposed algorithm significantly outperforms conventional methods.

  • Patent number: 10197519
    Abstract: An apparatus and method for sensing the amount of a gas in a fluid are disclosed. The apparatus may include a gas sensor, a temperature sensor, a first temperature adjusting unit, or a second temperature adjusting unit. The first and second temperature adjusting units may control the temperature of the gas sensor. The first and second temperature adjusting units may each be used to control the temperature of the gas sensor. According to one technique, they may be used simultaneously to control the temperature of the gas sensor. The temperature sensor may be used to sense the temperature of the gas when it has stabilized to the fluid temperature in which it is being used and the temperature of the gas sensor when it is being controlled by at least one of the first or second temperature adjusting units.

  • Publication number: 20180211346
    Abstract: Pickup location operations may be performed based on trusted user feedback. For example, a user may provide feedback that an ordered item at a pickup location is missing or damaged, in response to which a refund or replacement may be issued. Feedback may also be provided to indicate that a malfunction is occurring at the pickup location, in response to which the malfunctioning equipment may be disabled and a repair request may be made. Feedback may also be provided to indicate that a scheduled time period for a user to retrieve an item from the pickup location needs to be changed, in response to which an alternative time period may be selected.
