The MIPS SEAD -3

The MIPS SEAD -3 System engineering and development board is designed to provide a low-cost means to support various CPU cores allowing the user to evaluate the cores in an FPGA environment.

SEAD-3 also provides a user the ability to utilize the on board Xilinx FPGA for their own custom programming when a MIPS® FM-3 module is added to house the CPU core. When the FM-3 is added the user can then additionally stack on a MIPS® FPGA 5b board that can house up to two additional Xilinx XC5VLX330s providing extra design capacity.

MAX8881 and DS2490 Characterization for Cells

Rechargeable AA cells are very popular for a large variety of portable applications. The number of brands is also high, and the cell quality can differ considerably. Cell capacity is sometimes different from that specified, and the capacity often deteriorates dramatically after a limited number of discharge cycles. ....

See Maxim Application Note - Simple Characterization Circuit for Rechargeable AA Cells

https://www.maximintegrated.com/en/design/technical-documents/app-notes/3/3874.html

This characterization circuit, plus a PC and some software, accurately measures the full discharge cycle for a rechargeable AA cell. Cell capacity and output resistance can easily be determined from the curve resulting from these measurements.

MAX8881 and DS2490 Characterization for Cells

In Figure 1, the simple circuit is connected to the USB port of a PC. No external power source is required because power is extracted from the USB bus voltage. U1 (DS9490R) is a USB dongle that converts the USB protocol to the 1-Wire® protocol, thereby allowing the PC to communicate with the key circuit component (U2).

How does a telephone line work?

"There are several different states that the phone line can be in, depending upon what the phone is doing, and what the phone company is doing to the phone. The central office (or nearby equivalent) applies various DC and AC voltages to the two-wire phone loop (labeled "tip" and "ring") during these various stages of call progress. In the idle state, the telephone company central office applies -48(±6) Vdc...."
