  • Patent number: 10895457
    Abstract: A MEMS resonant accelerometer includes two proof masses configured to resonate when driven with periodic signals. Each proof mass includes a resonator structure that vibrates relative to the proof mass and a dummy structure that does not resonate. When driven by a periodic drive signal, the resonator structures of the two proof masses may be used to determine the magnitude of acceleration in the direction perpendicular to the planes of the proof masses by sensing the frequency at which the resonators vibrate. For example, a differential oscillation frequency may be computed from the two sensed frequencies. The dummy structures are used to make the mass distribution of the two proof masses similar.

  • Patent number: 10890874
    Abstract: An image forming apparatus includes an apparatus cover, first and second exposure units, and an orientation setting mechanism. The apparatus cover opens or closes by pivoting about a rotation fulcrum with respect to an apparatus body. The first exposure unit is disposed at a first position, on an inner surface, spaced apart from the rotation fulcrum. The second exposure unit is disposed at a second position, on the inner surface, closer than the first position to the rotation fulcrum. The orientation setting mechanism sets an orientation of the first exposure unit to a first direction approaching the apparatus body in a closed state. The orientation setting mechanism sets it to a second direction further away than the first direction from the rotation fulcrum and sets the orientation of the second exposure unit to a third direction between the first and second directions when the opening angle is a first angle.

  • Patent number: 10890639
    Abstract: Systems and methods are provided for correlating functional magnetic resonance imaging (fMRI) with gene expression. Brains of first and second sets of patients are imaged at first and second times to provide first and second sets of fMRI images. Blood is drawn from each of the first and second sets of patients at the first and second times to provide first and second sets of gene expression transcripts. A therapeutic is administered to the first set of patients between the first and second times. A change in the connectivity of the brain for each patient is determined from the first and second sets of fMRI images. A set of changes in the peripheral lymphocyte gene expression that are correlated with changes in the connectivity of the brain are determined from the change in the connectivity of the brain for each patient and the collected imaging and gene expression data.

  • Patent number: 10884037
    Abstract: An angular resolver system includes, for example, an imbalance detector for detecting degraded resolver output signals. The imbalance detector includes a first and second power averaging circuits and a comparator circuit. The first power averaging circuit includes a first integrator for generating over a first time window a first average power signal in response to resolver sensor output signals. The second power averaging circuit includes a second integrator for generating over a second time window a second average power signal in response to the resolver sensor output signals, where the first time window is longer than the second time window. The comparator circuit compares the first average power signal and the second average power signal and generates a fault signal when the first average power signal and the second average power signal differ by a selected voltage threshold.

  • Patent number: 10884085
    Abstract: A system for performing magnetic resonance imaging (MRI) of a subject has a pulse sequence system that generates a pulse sequence and has a gradient system, a plurality of gradient coils, a radio-frequency system, and a plurality of RF coils. The pulse sequence system causes the subject to emit MR signals which are captured as k-space data. The system also has a k-space ordering processor that collects first k-space data and second k-space data, an MR signal modeler that generates a signal variation model, and a compensation module that applies the signal variation model to the second k-space data collected to produce compensated k-space data. A display processor reconstructs the compensated k-space data into an image of the subject. The compensated data accounts for variation in magnetization during the pulse sequence and k-space data collection to reduce artifacts in the images.
