At maximum coverage observers on the eclipse track will see a ring of sunlight around the moon. The name comes from the Latin word annulus meaning ‘ring.’ Annular eclipse…

    One-hot state machine design for FPGAs by Steve Golson Abstract: One-hot state machines use one flop per state. They are particularly suited to today’s register-rich FPGA architectures. This paper will discuss the advantages of one-hot state machines including ease of design, simple timing analysis, and high clock rates. An SBus master/slave interface will be used…

    A lunar eclipse occurs when the moon enters the earth’s shadow. The Greek philosopher Aristotle observed that during a lunar eclipse the shape of the shadow seen on the moon is always round. The only shape that always casts a round shadow is a sphere; thus Aristotle concluded that the earth was spherical some eighteen…
