  • Patent number: 11839210
    Abstract: The present invention uses compound 3-OH-?-apo-13-carotenone (zaxinone) as a negative regulator of the plant hormone strigolactones (SLs). The compound 3-OH-?-apo-13-carotenone is a positive growth regulator which triggers the formation of crown roots and promotes growth in size and number of roots and shoots. Disclosed herein is a method of using 3-OH-?-apo-13-carotenone as a growth-promoting compound for cereal, grain and vegetable crops. The 3-OH-?-apo-13-carotenone compounds is also a negative regulator of strigolactone biosynthesis and release. Disclosed herein is a method of combating root parasitic weeds affecting cereal, grain and vegetable crops. Application of 3-OH-?-apo-13-carotenone to plant growth media down-regulates strigolactone production in cereal, grain and vegetable crops preventing root parasitic weed infestation of the crops by inhibiting germination of parasitic weed seeds.

  • Patent number: 11781885
    Abstract: An energy-efficient capacitance-to-digital converter (CDC) is provided that utilizes a capacitance-domain successive approximation (SAR) technique. Unlike SAR analog-to-digital converters (ADCs), analysis shows that for SAR CDCs, the comparator offset voltage will result in signal-dependent and parasitic-dependent conversion errors, which necessitates an op-amp-based implementation. The inverter-based SAR CDC contemplated herein provides robust, energy-efficient, and fast operation. The inverter-based SAR CDC may include a hybrid coarse-fine programmable capacitor array. The design of example embodiments is insensitive to analog references, and thus achieves very low temperature sensitivity without the need for calibration. Moreover, this design achieves improved energy efficiency.
