We present results on heavy-ion and proton irradiations for commercial SiGe BiCMOS differential amplifiers: LTC6400-20 from Linear Technology and THS4304 from Texas Instruments. We found that the devices are susceptible to heavy-ion-induced SETs, with relatively low LET thresholds (LETth). The LTC6400 exhibits a LETth < 7.4 MeV•cm2/mg for(More)
Robotic rehabilitation has proven to be cost-effective in accelerating the rehabilitation process by eliminating the constant need for supervision by a therapist. This work aimed to design and develop a novel three-dimensional (3D) printable non-assembly five-fingered robotic hand exoskeleton for rehabilitation. A single degree-of-freedom (DOF) linkage was(More)
We present results on the effects on ELDRS at dose rates of 10, 5, 1, and 0.5 mrad(Si)/s for a variety of radiation hardened and commercial devices. We observed low dose rate enhancement below 10 mrad(Si)/s in several different parts. The magnitudes of the dose rate effects vary. The TL750L, a commercial voltage regulator, showed dose rate dependence in the(More)
A b s t r a c t — We will discuss the use of cat's eye modulating retro-reflectors based on quantum well (MQW) modulators for free space optical data transmission. Two kinds of systems will be described. The first is based on non-diffraction limited cat's eyes using telecentric lenses. These systems were used to implement a short-range optical link (3(More)
