Abstract: The present disclosure describes system and methods for detecting and amplifying weak magnetic fields generated by anatomical structures. The disclosure describes an implantable magnetic reporter system. The magnetic reporter system includes a magnetic reporter. The magnetic reporter includes a platform coupled to a support structure by a plurality of torsional flexures. A magnet is disposed on the platform, and the magnet and platform rotate when exposed to a magnetic field. The rotation of the magnet generates a stronger magnet field that is detectable external to the patient.

Abstract: An interconnect scheme includes a conductive ink forming a plurality of conductive regions, and a dielectric ink occupying spaces between the conductive regions. The conductive ink and the dielectric ink have substantially identical optical, acoustic, and x-ray absorption properties, thereby making the interconnect scheme tamper-resistant and/or difficult to identify and reverse-engineer using conventional detection methods.

Abstract: In one embodiment, an accelerometer includes a suspension frame, a proof mass, and a plurality of flexures suspending the proof mass from the suspension frame. The flexures allow the proof mass to deflect in response to an acceleration along a sensitive axis of the accelerometer. Each flexure exhibits an initial spring rate along the sensitive axis of substantially zero.

Abstract: A micromechanical device is provided, which includes at least one flexible member formed from an alloy, where the alloy is made up of one or more noble metals and one or more alloying elements, wherein each of the alloying elements has an equilibrium solid solubility in the noble metal, and wherein the one or more alloying elements are present in an amount that does not result in precipitates. A method for making a micromechanical device includes depositing an alloy on a substrate to form at least one flexible member, the alloy comprising one or more noble metals and one or more alloying elements, wherein the one or more alloying elements form a solid solution with the one or more noble metals; and removing a portion of the substrate or a sacrificial layer beneath the deposited alloy layer to obtain a flexible member.

Abstract: An array of movable MEMS mirror devices is provided being electromagnetically actuated in one axis and using an additional set of coils, or a single coil, positioned off of the main axis of rotation to achieve a second axis of rotation while allowing for a very high linear mirror fill factor (>80%). This second set of coils, or second electrically wired coil, is capable of generating the necessary torque about an axis that is perpendicular to the major axis of rotation. A second embodiment is provided using electromagnetic actuation in one axis of rotation, which typically has larger rotation angles than the second axis, and electrostatic actuation in the second axis of rotation. Electrostatic pads can be used to sense rotation. When staggering adjacent pixels a center array of mirrors with no coils or electrodes provides increased radius of curvature and reducing undesirable cross-talk between adjacent mirror devices.
