摘要:
A system and a method for providing farmers/producers with crop characteristic predictions for standing crops located in fields includes a central database for storing field and crop information for the crops. A weather data processor receives raw weather data from either or both of (1) a weather data service with collected weather data from a plurality of weather stations; and (2) one or more site-specific weather stations associated with a particular field whose information is in the database. The raw weather data are processed to obtain field weather parameters for entry into a crop characteristic prediction equation, and the parameters are stored in the central database. With a user interface, a crop whose information is stored in the central database is selected. A computer calculates a crop characteristic prediction for the selected field based on the crop and field information stored in the central database, including the field weather parameters in the database, and the crop characteristic prediction formula. The producer uses the prediction to determine time of harvest. In one embodiment, the crops are alfalfa crops and the crop characteristic is neutral detergent fiber content.

A MIMO radar transceiver assembly includes a plurality of transceiver circuit regions and a plurality of antennas. The plurality of antennas include a first transmit antenna coupled to a first transceiver circuit region among the plurality of transceiver circuit regions, a first receive antenna coupled to the first transceiver circuit region, a second transmit antenna coupled to a second transceiver circuit region among the plurality of transceiver circuit regions, and a second receive antenna coupled to the second transceiver circuit region. At least one of the second transmit antenna and the second receive antenna is interleaved between the first transmit antenna and the first receive antenna. Interleaving of the antennas can increase virtual aperture and angular resolution of the radar system without increasing physical dimensions of the transceiver assembly.

Purified nucleic acids, vectors and cells containing a gene cassette encoding at least one modified bioluminescent protein, wherein the modification includes the addition of a peptide sequence. The duration of bioluminescence emitted by the modified bioluminescent protein is shorter than the duration of bioluminescence emitted by an unmodified form of the bioluminescent protein.

Methods and apparatus for accessing flash memory in a continued burst mode are provided. The apparatus includes a processor for executing instructions including memory access instructions, the processor generating a next access signal that indicates if a next memory access is in sequence with a current memory access, a memory having a continued burst mode of operation, and a bus interface for controlling access to the memory in response to the memory access instructions. The bus interface unit enables the continued burst mode of the memory while the next access signal is asserted.

Methods and apparatus are provided for operating an embedded processor system that includes a processor and a cache memory. The method includes filling one or more lines in the cache memory with data associated with a first task, executing the first task, and, in response to a cache miss during execution of the first task, performing a cache line fill operation and, during the cache line fill operation, executing a second task. The cache memory may notify the processor of the line fill operation by generating a processor interrupt or by notifying a task scheduler running on the processor.

A conventional grenade shell launcher contains a laser generator shell thin which directs a blinding flash of light at an adversary to temporarily induce blindness of the adversary carrying out unlawful or dangerous actions such as pointing a weapon at police officers or others. The laser generator shell can be rapidly removed from the launcher, and conventional tear gas grenades or the like can be fired by the grenade launcher at the adversary to induce his surrender. This mode of operation is enabled by detachably coupling a laser triggering transmitter to the launcher. The wide angle light beam directed at the adversary also eliminates the need to accurately aim the device to disable the adversary.

A digital baseband processor is provided which receives a system clock generated by a system oscillator and generates a plurality of clock signals from the system clock. The digital baseband processor includes a digital signal processor for executing digital signal processor instructions, a microcontroller for executing microcontroller instructions, and other modules which may require one of the plurality of clock signals for operation. The digital baseband processor also includes a power management circuit which may power down the system oscillator when modules such as the digital signal processor and microcontroller do not require clock signals derived from the system oscillator. The power management circuit may gate off clock signals to modules when those modules do not require clock signals, without powering down the system oscillator.
摘要:
The invention relates to a process for preparing quinoline-substituted carbonate and carbamate compounds, which are important intermediates in the synthesis of 6-O-substituted macrolide antibiotics. The process employs metal-catalyzed coupling reactions to provide a carbonate or carbamate of formula (I) or (II) or a substrate that can be reduced to obtain the same.
