Abstract: METHOD FOR LOCALLY ENHANCING      ELECTROPLATING RATES     Abstract A method for high resolution maskless electro-plating is described.  Preferential plating results from exposing those regions where enhanced plating is sought to a collimated energy beam.  Such exposure can produce an enhancement in the plating rate of 103, which is sufficient to eliminate the necessity of masking the surface.

Abstract: FLUIDIC MOTOR ACTUATOR ABSTRACT OF THE DISCLOSURE A control system for a motor through which a specific rotary output is obtained from a given input signal by controlling an operational supply of fluidic energy.  The control system includes a direct mechanical servo which receives the input signal to control a rotary plate directional valve through which the operational supply of fluid is communicated to the motor.  The direct mechanical servo includes a compound epicyclic sear train and an intermittent motion gear mechanism which compares the input position with the output position of the motor to establish a feedback signal which repositions the rotary valve plate directional valve to a null position when the rotary output equals that requested by the input signal.  The control system further includes a regulator assembly which receives a variable reference signal to control the fluid pressure of the supply fluid.  The variable reference signal which represents the work performed by the motor also passes through a relief valve. When the output torque of the motor reaches a predetermined value, the relief valve opens and a portion of the fluid supplied to the motor is vented to an exhaust conduit to protect any mechanism operated by the motor from receiving excessive torque.

Abstract: ABSTRACT A datapath system and protocol is disclosed in which data is trans-ferred between a computer memory and one or more peripheral devices through device controllers, each of which includes a buffer, through periodic connection of the device controller to the channel.  The system and proto-col are structured to permit multiple device controllers to cooperatively interact on a single channel, without direct communication between device controllers.  Each device controller monitors the level of stress on its buffer and at appropriate times presents a reconnect request to the channel, together with indicia for permitting the channel to determine the priority of a particular request relative to other reconnect requests.  The times at which a reconnect signal should be presented are determined by monitoring the level of information storage in the buffer and relating that level to a threshold level; both overfilling and overemptying are prevented.  The threshold level can be varied in accordance with a criteria which makes allowance for the number and combination of device controllers attached to the channel; and is set such that the remaining space in the buffer is sufficient to allow the buffer to transfer data to or from the associated peripheral device, at the rate demanded by that peripheral device, long enough to allow the channel to connect to one lower priority device controller, and all higher priority device controllers.  The threshold level and buffer size are also set such that, after a reconnect, the buffer is capable of transferring data to or from the associated peripheral device, at the rate demanded by the peripheral, long enough for the channel to re-connect to all lower priority device controllers, to ensure that all device controllers, no matter the priority, are allowed access to the channel.          The invention has broad application, but is particularly well-suited to fault tolerant computing systems.
