    摘要： An analog output control circuit provides an arrangement whereby digital data from the control computer is supplied simultaneously to a number of output boards along with address data for selecting a particular one of the several boards. Logic control means is provided for responding to an address code for enabling the selected board. Additional control logic is provided for responding to control signals from the computer for selecting a particular one of the several output units included on the output circuit board. Control logic is also provided to prevent the output units from being changed in the absence of logic control or power supply.

    摘要： Method and apparatus for controlling a machine which is operable in cycles, the machine carrying out a plurality of functions during each cycle. Values representing the stages of the machine in its cycle are generated as the machine progresses through a cycle, the values being determined by the actual stage of the machine independently of time. Starting and stopping points in the cycle for at least one of the functions of the machine is preset in terms of the generated values. The generated values are compared with the preset starting and stopping point values. The machine function is initiated and maintained when the generated values are greater than the preset starting point value but are less than the preset stopping point value and the function is stopped when the generated values equal or are greater than the preset stopping point value. Apparatus and method for computing starting and stopping points for an eyespot window using only a single set of delay switches is also disclosed.

    摘要： A supervised start system for microprocessor based appliance controls and effective to prevent unwanted start operation of the associated appliance due to failure of a critical component of the starting system. The starting system requires a mechanical operation to effect starting of the associated appliance and the system tests all critical components thereof and failure of one component thereof will either render the associated appliance inoperative or cause an obvious but safe malfunction of the associated appliance.

    摘要： A removable package for use primarily in an ambulatory monitoring device, such as a medical monitor includes a RAM and a power supply. The RAM package is connected to an external device via an edge connector which includes interlock means for sensing when the removable RAM package is properly connected to the external device in order to prevent inadvertent writes into the RAM. In a preferred embodiment of the invention disclosed, the removable RAM circuit also includes a microprocessor compatible real time timer which is connected to the same data and address buses as the RAM.
