A novel, unobtrusive and wearable, multiparameter ambulatory physiologic monitoring system for space and terrestrial applications, termed LifeGuard, is presented. The core element is a wearable monitor, the crew physiologic observation device (CPOD), that provides the capability to continuously record two standard electrocardiogram leads, respiration rate(More)
The rst micromachined bimorph organic ciliary array with on-chip CMOS circuitry is presented. This device is composed of an 8 8 array of cells each having four orthogonally oriented actuators in an overall die size of 9:4mm 9:4mm. The polyimide based actuators were fabricated directly above the selection and drive circuitry. Selection and activation of(More)
The first micromachined bimorph organic ciliary array with on-chip CMOS circuitry is presented. This ciliary array is composed of an 8 8 array of cells each having four orthogonally oriented actuators in an overall die size of 9.4 9.4 mm. The polyimide-based actuators were fabricated directly above the selection and drive circuitry. Selection and activation(More)
Strains of Heterococcus endolithicus sp. nov., H. pleurococcoides Pitschmann, H. caespitosus Vischer, and H. protonematoides Vischer isolated from terrestrial habitats in Antarctica were studied in culture. Morphology of the algae changes with stage in life history. The characteristic branching patterns are not present in very young or old cultures. (More)

In this article, we present general properties of xed-point groups of the automorphisms of nite groups. Speci cally, we determine the form of xed-point groups and partition Aut(G) according to the number of xed points possessed by each automorphism. A function θ records the size of each partitioning set; we nd properties for θ in general and develop(More)
This paper describes a walking microrobot with 512 thermobimorph polyimide actuator legs. Eight groups of unidirectional legs can be separately controlled to produce planar motion with three degrees of freedom. Wave-like gaits propel the robot at speeds of up to 250 μm/sec while consuming approximately 1.6W power. Finite element methods are employed to(More)
