摘要： A seaweed-based commercial salmon feed additive which replaces the synthetic chemical additives that are currently used in salmon fish feed is provided. Synthetic additives are replaced with a combination of seaweed species thereby providing a natural product that improves the nutritional value of the farmed fish, qualifies the fish for marketing as organic, reduces the environmental impact of fish farming practices and may replace the chemical use of lice treatment.

摘要： A circuit for testing digital-to-analog (DAC) and analog-to-digital converters (ADC) is provided. The circuit applies a code pattern having a plurality of sequential values to the digital to analog converter. A plurality of built-in test switches (BTS) couple at least one tap voltage from the DAC to a test bus and to the ADC as a variable reference input voltage. In one form, the circuit uses incremental digital codes to test for defects in a resistor string, a switch array, and a decode logic that form part of the DAC. In another form, the circuit uses the tap voltages from the DAC to test the comparators that form part of the ADC. Instead of performing time-consuming analog to digital conversions, the functionality of the above mentioned circuitry is tested by varying the code pattern around a reference point and by selecting the appropriate combination of BTS switches.

摘要： A telephone switch in which communication between tasks controlling the switch hardware and the timing of those tasks, including the timing of repeating tasks, is controlled through a mail system in which mail messages are sent between tasks that may be running on separate microprocessors. The mail messages specify the destination task, the function that the task is to perform and any desired delay before the mail is to be delivered to the destination task. Repeating tasks send mail to themselves each time they repeat, specifying in the mail message the task to be repeated and the desired delay interval. A mail task holds the mail for the specified delay interval before it is delivered, and receipt of a mail message causes the task to run.
