A control system having a host computer and one or more control computers connected to an interface for control of a process or machinery. The control computers are capable of automatically initiated network address assignment and configuration when powered up after installation. The network address is based on a location identifier situated in the interface that corresponds to a specific connection thereof to the control computer. The control computer reads the location identifier from the interface and requests a network address. The host computer assigns the network address based on the location identifier. Configuration of the control computer then proceeds. The procedure applies to newly installed control computers, whether first time installment or a replacement for a failed control computer.

Persistent configuration in a multiple processor repairable system

A diver's helmet is retained on the diver's skull by curved retainer rods hinged to each side of the helmet. Connected to the hinged rods are rotary handles operated by the diver to rotate the rods under the jaw and base of the skull to retain the helmet, and rotated away from the diver's head to permit doffing and donning of the helmet. The retainer can be combined with a neck dam to clamp the elastic dam against the diver's jaw and skull to prevent ballooning of the neck dam and thereby prevent a change in buoyancy. When the retainer rods are hinged to helmet they act to retain the neck dam to the helmet.

Helmet retainers operated by rotary handles

A head enclosing helmet structure is provided including a fluidtight front viewing window and a lower access opening for upwardly removably receiving the head of the wearer of the helmet therethrough. The outer surface portions of the helmet portions disposed about the lower access opening are generally cylindrical and an annular collar of deformably and compressible material is wedgingly removably receivable between the inner surfaces of the access opening of the helmet and the opposing neck surfaces of the wearer. A hollow tubular and endwise tapering flexible neck dam provided with a supportive radially contractable mounting ring on its major diameter end is removably clampingly engageable about the cylindrical outer surface portions of the helmet extending about the access opening therein and a generally horseshoe-shaped yoke is provided for removable disposition about the neck of the wearer of the helmet and provided with releasable anchor means for securement to the mounting ring with the portion of the neck dam disposed between its opposite ends compressively clamped between the upper surface portions of the yoke and the undersurface portions of the collar, the latter being upwardly seatingly engageable within the access opening of the helmet against the lower portions of a resilient head cushioning liner within the helmet.
