The flange is shaped in such a way that stepping on the flange with one's foot flips the projectile into a vertical position so that it can be loaded into the launcher hands-free. The launcher comprises a curved arm and a straight arm disposed on opposite sides of a C-shaped cup, so that swinging the launcher around in an arc will release the toroidal projectile with topspin and velocity.

Abstract: Fertilizer granules containing elemental sulfur and a hydrogel which expands or swells in the soil to more readily disperse the elemental sulfur surface throughout the soil, which increases the elemental sulfur surface area available for oxidation, and ultimately uptake of sulfur by the plant. The elemental sulfur and hydrogel can be added to a fertilizer composition as either an exterior coating or co-granulated with the base fertilizer composition.

Abstract: An oil-based coating for fertilizer granules impregnated with an alpha olefin wax additive and related methods of applying the oil-based coating. The alpha olefin wax additive increases the viscosity of the oil-based coating and provides a substantial improvement to moisture resistance, thereby increasing the duration for which the coating is capable of controlling or inhibiting the formation of dust particulates from the fertilizer granules.

Abstract: A phasor-based signal detector includes a signal processor to detect symbols in a received signal in the presence of an offset between the carrier frequency and an oscillator frequency of the signal processor. The signal processor calculates a phasor that indicates a phase difference between a first sample in a first symbol group and a second sample in a second symbol group. The first and second samples each include a real part and an imaginary part corresponding to a same sample position within the first and second symbol groups. Calculating the phasor includes a complex multiplication of one of the samples and a conjugate of the other one of the samples. A phase difference indicated by a phasor meeting a criteria may be used to estimate a carrier frequency offset (CFO). If the CFO is within a supported range, the signal processor may coherently accumulate symbols.

Abstract: A receiver circuit for detecting and waking up a wakeup impulse sequence is provided. Herein, a transmitter circuit is configured to transmit a wakeup impulse sequence to wake up a receiver circuit. The receiver circuit includes a main receiver circuit and a wakeup receiver circuit. The main receiver circuit, which consumes far more energy than the wakeup receiver circuit, will remain in sleep mode as much as possible to conserve power. While the main receiver circuit is asleep, the wakeup receiver circuit is configured to detect the wakeup impulse sequence and wake up the main receiver circuit if the wakeup impulse sequence is intended for the receiver circuit. By keeping the main receiver circuit asleep as much as possible, it is possible to reduce power consumption, thus making the receiver circuit an ideal receiver option for an Internet-of-Things (IoT) device(s).

Abstract: Disclosed are methods for time-of-flight (TOF) ranging between wireless devices using single-sided two-way ranging (SS-TWR) and double-sided TWR (DS-TWR) exchanges. The SS-TWR method involves performing the exchange between the wireless devices and determining a first path angle, a relative carrier frequency offset of the initiator and responder devices, and response delay of the responder. The method also involves determining a single SS-TWR delay and calculating a TOF delta from the determined information. Finally, the method involves calculating the TOF using the TOF delta with the single SS-TWR delay. The DS-TWR method eliminates the need for the relative carrier frequency estimation. Both methods enable accurate ranging between wireless devices by considering first path angles, and delays delay, which can be used in a variety of applications such as localization and tracking of objects. The method can be implemented on a processor of one or more of the wireless devices.
