Abstract: A gateway for a computer network includes a programmable integrated circuit device, and a first port and a second port coupled to the programmable integrated circuit device. The programmable integrated circuit device is structured and configured to, responsive to a restoration of power to the gateway following a loss of power at the gateway, read configuration information stored by the gateway, and if indicated by the configuration information, forward first data traffic from the first port to the second port and forward second data traffic from second port to first port until the programmable integrated circuit device is configured to do otherwise.

Abstract: There is disclosed an apparatus for monitoring and calculating the position and speed of a projectile as it is pitched over a target zone. A grid of infrared emitters aligned with respective infrared receivers are in continuous optical links until the ball passes an d cuts some of the links. Upon this cut, the position of the ball is stored in memory and the time of passage of the ball across the grid is recorded to later calculate the speed of the ball. The infrared grid is enclosed in a chamber to prevent interference of external light rays with the reception of the receivers.
