A solid-state speed controller for capacitor motors driving ventilation fans
Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 1992Co-Authors: M.m. Morcos, J.a. Mowry, A.j. HeberAbstract:The authors document the design and testing of an electronic speed controller for permanent-split capacitor motors driving agricultural ventilation fans. The controller was developed and tested with three commercially available and widely used fan systems. Linearized temperature versus airflow rate characteristics were obtained. The controller circuit uses an erasable Programmable Read-Only Memory (EPROM) chip. The input to the EPROM is an analog representation of temperature converted to digital form. The digital contents then are converted to an analog signal that triggers a triac and consequently controls the voltage input in the fan motor. A linearized control characteristic can be obtained by storing appropriate voltage values in the EPROM. These values correspond linearly to the desired fan speeds. >

Single-component microcomputer-driven assessment of attention
Behavior Research Methods Instruments & Computers, 1990Co-Authors: Ernest M. Post, Mitchel S. Burko, Michael GordonAbstract:The Gordon Diagnostic System (GDS) is a single-component microcomputer-based instrument that can be used to administer 11 psychological tests. The game-like tasks provide objective data for evaluating possible attention-deficit hyperactivity disorder or other conditions that affect a person’s ability to sustain attention and exert self-control. The core of the instrument is an integrated circuit with a microprocessor, a random access Memory, and an erasable, Programmable Read-Only Memory (EPROM). It can be programmed with an IBM PC and an EPROM programmer. The assembly language source is compiled into machine language, which is used to simulate the GDS on the IBM PC or is “burned” into the ROM. The Memory is erasable with ultraviolet light, so revisions can be made easily. The GDS illustrates that “custom” programming a ROM is not limited to large industrial concerns, and that it can be done within small research groups.

Total dose characteristics of single poly EEPROM and SONOS EEPROM on SOI
2011Co-Authors: Xiao Zhiqiang, Li Leilei, Xu Jing, Chen Zheng-caiAbstract:Devices of single poly electrically ersable Programmable read only Memory (EEPROM) and silicon-oxide-nitride-oxide-silicon (SONOS) EEPROM on silicon on insulator (SOI) are fabricated on self-built 0.8 μm SOI process. And through a set of experiments on EEPROMs of these configurations and comparisons, SOI SONOS EEPROM is successfully developed with good and stable total dose radiation hardened characteristics. These provide stronger proofs to choose EEPROM in radiation hardened circuits.
