    Abstract: A polysilicon micromotor, of either inner rotor or outer rotor design, is fabricated with a process that uses as few as three mask steps. In an outer rotor (wobble) micromotor, a free-rotating insulating flange bearing (14) mechanically couples the inner periphery of the rotor (16) to the stator (12), permitting the outer periphery of the rotor to be directly coupled to other mechanisms. The dielectric constant of the flange bearing (14) increases motive torque of the motor as contrasted with air-gap designs. This and other factors result in motive torque, in the illustrated embodiment, more than 100 times larger than in previous designs. Among its other benefits, the disclosed fabrication process results in in-place formation of all motor elements, and enables precise definition of the rotor/stator gap.

    Abstract: The present invention relates to the development of a new class of oligonucleotide surrogates capable of sequence specific binding to simple stranded DNA and RNA as well as to double stranded DNA targets. More specifically, structures (Ser/Thr[CH2B]-AA[P])n below represent the repeating structural units for a number of the nucleic acid surrogates of the present invention. Once synthesized (in suitably protected form), the monobasic units are linked together via peptide bonds to produce the required oligomeric structures having defined nucleobase sequences. These nucleic acid surrogates may then be utilized for use as antisense/antigene probes and/or drug carriers.

    Abstract: A self-curling sheet (A) of a nonconductive material is biased to curl into a tight cylinder. Inwardly extending conductive members (B) are disposed on the surface of the sheet forming the inside of the cylinder. Circumferentially separated longitudinal slices (30) are made in the cylinder adjacent the conductive members (B) forming spring members (52) such that, as the sheet (A) relaxes over time, electrodes (11) on the spring members (52) engage and pierce a nerve surrounded by the cuff. The conductive members (B) may be electrically conductive for applying electrical impulses or fluid conductive for infusing medications. In use, a first edge of the self-curling sheet (A) is disposed adjacent a nerve trunk which is to receive the cuff there around. The self-curling sheet (A) is controllably permitted to curl around the nerve into its original cylindrical shape. Over a period of a few days, the electrodes (11) riding on spring members (52) formed by longitudinal slices (30) into the cylinder are embedded in the nerve without damage to the perineurium membrane surrounding the nerve axons. The electrodes (11) displace the fascicles rather than damaging them by piercing the perineurium.
