X-Message-Number: 8995 From: Date: Tue, 13 Jan 1998 14:49:27 -0800 (PST) Subject: Job Opening JOB OPENING * Background Trans Time, Inc. is a service organization that places and maintains patients in cryonic suspension after legal death in hope of their future reanimation. We are located in San Leandro, CA (near Oakland). A cryonics patient is first perfused with cryoprotectants, then cooled in stages to the temperature of dry ice (-79 degrees C). Next we place the patient into a vacuum insulated cryogenic dewar, and slowly add liquid nitrogen until the patient reaches -196 degrees C. We monitor the patient's temperature at several body locations during this cooling. We control the rate of adding liquid nitrogen to the dewar based on these body readings, in such a way as to minimize thermal stresses within the patient. We are developing a computerized system to control this last phase of the cooldown. * Job Description 1. Do the programming to control the cooldown. This will require setting up a PID (proportional-integral-derivative) controller. We will use the software LabWindows/CVI from National Instruments. This program has C as the underlying language, and has many tools for automating the visual design of the cooldown system, including PID tools. 2. Convert about 900 lines of current QuickBasic code to ANSI C. 3. Run ongoing tests of the developing system, using a small liquid nitrogen dewar to cool an instrumented sample such as a chunk of beef. * Job Requirements 1. Command of programming in C. 2. Enough knowledge of Basic to be able to convert QuickBasic to C. 3. Laboratory experience, such as with thermocouple thermometers, relay boxes, and liquid nitrogen dewars, is valuable. * Hours Hours are flexible. The job should take at least four man-months, and could evolve into a full-time job. * Compensation Compensation is dependent upon qualifications and experience. * Contact Please send your resume to , or respond to: Art Quaife, Ph.D., President Trans Time, Inc. 3029 Teagarden St. San Leandro, CA 94577 510-297-5577 Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8995
