Electric Company, Mr. Wojciechowski has been engaged in the develop- 

 ment of electrical measuring apparatus. Particularly, his work has been 

 concerned with the industrial precision measuring problems growing out 

 of war and post-war changes in electi'onic techniques. Some of his con- 

 tributions are: the development of bridges for temperature coefficient 

 measurements of capacitance ; inductance measurements of quartz crystal 

 plates ; unbalance measurements of four-branch networks ; phase sensitive 

 detectors; and digital frequency combining and selecting systems. Mr. 

 Wojciechowski is a Member of the American Institute of Electrical 

 Engineers and a Senior Member of the Institute of Radio Engineers.
