Automated and semi-automated pollen delivery in grain production
This invention describes a new method to increase grain yields in any crop plant by modifying pollination to effect an increase in grain yield, a change in grain content or characteristics, a decrease in contamination, or a combination of these attributes. The process involves the intentional delivery of pollen of the male plant at will via automatic or semi-automatic means, as available either in a preserved pollen bank, or real-time collection from male plants as they become available, in a growth chamber for example. Desired pollen is delivered to fertile females. The delivered pollenM is in such amounts and fortuitously timed that it preferentially pollinates the females and avoids self-pollination or pollination from neighboring plants. The intentional delivery of genetically different pollen will result in increased heterosis and accompanying grain yield increases resulting from increased grain size and the potential to influence grain content and constituents. The invention also permits real-time agronomic decision making in order to maximize grain yield by overcoming biotic and abiotic challenges in the growing season which may or may not have been anticipated. |

Switch-less connection for radio-frequency (RF) transceivers
A switch-less transceiver has parallel LC resonances that act as OFF switches and series LC resonances act as ON switches when resonating at the transmit (TX) or receive (RX) frequency. When the transmitter is disabled, no current flows through series LC filters. Instead, series impedances to ground provide an RF ground to the transmitter output node. A TX inductor between the transmitter output node and the antenna is in parallel with a TX blocking capacitor to ground, which together form a parallel resonance to ground that has a high impedance when resonating at the receiver frequency. This high impedance acts as an OFF switch to block antenna signals from entering the transmitter. The two paths are in parallel, presenting a high impedance to the antenna and forming an OFF switch when the receiver is disabled. |

Digital-to-analog converter and generation of high-bandwidth analog signals
A controlled switch having N inputs and a single output (N≥2) is switchable between N states. In each state a respective one of the inputs is connected to the single output. There are N sources of sub-streams of analog samples, each sub-stream composed of pairs of adjacent analog samples. Each source is coupled to a respective one of the inputs. In operation, the controlled switch is controlled by a control signal to switch between the N states. While the controlled switch is in any one of the states, a data transition occurs between two adjacent analog samples in the sub-stream whose source is coupled to the input that is connected to the single output. The single output yields a high-bandwidth analog signal. Any pair of adjacent analog samples in any one of the sub-streams substantially determines a corresponding pair of adjacent analog samples in the high-bandwidth analog signal. |

Transistor with isolation below source and drain
A transistor includes a body of semiconductor material with a gate structure in contact with a portion of the body. A source region contacts the body adjacent the gate structure and a drain region contacts the body adjacent the gate structure such that the portion of the body is between the source region and the drain region. A first isolation region is under the source region and has a top surface in contact with a bottom surface of the source region. A second isolation region is under the drain region and has a top surface in contact with a bottom surface of the drain region. Depending on the transistor configuration, a major portion of the inner-facing sidewalls of the first and second isolation regions contact respective sidewalls of either a subfin structure (e.g., FinFET transistor configurations) or a lower portion of a gate structure (e.g., gate-all-around transistor configuration). |
