  • Patent number: 10281486
    Abstract: The structure enables two-directional sensing of accelerations with compact component dimensions and with minimal cross-axis sensitivity. The rotation mass includes a first frame and a second frame. In one sense direction, the structure employs a combined proof mass of the first frame and the second frame, which improves the signal to noise level achievable with said device dimensions. In the other sense direction, a detection structure with at least two sensing elements is used to detect displacements of the proof mass of the second frame. Due to the specific internal configuration of the detection structure, signal contributions of the sensing elements in the one direction cancel each other.

  • Patent number: 9720012
    Abstract: An inertial sensor includes first and second movable elements suspended from a substrate and interconnected by a beam. The second movable element is positioned laterally adjacent to the first movable element, and each of the movable elements has a mass that is asymmetric relative to a rotational axis. A first spring system couples the first movable element to the substrate and a second spring system couples the second movable element to the substrate. The spring systems and the beam enable the movable elements to move together in response to force imposed upon the movable elements. In particular, the first and second movable elements can undergo in-plane torsion motion in response to force, such as acceleration, imposed in a sense direction. Additionally, damping structures may be integrated into the first and second movable elements to effectively increase a damping ratio of the device resulting from the in-plane torsion motion.

    Abstract: A system and a method for determining a true acceleration and velocity of a locomotive and for controlling wheel slip and wheel skid of the locomotive is disclosed. The system, using accelerometers, can control the velocity of the wheels of the locomotive based on the comparison between a true locomotive velocity signal and a wheel velocity signal such that an actual tangential speed of the wheels is regulated to correspond to the true locomotive longitudinal velocity plus an allowance velocity for creepage. The accelerometer can also be used at the same time for impact detection purposes. Furthermore, if a set of accelerometers are used, the locomotive can also play a diagnostic role for track quality reporting in rail yards. The control of wheel slip and wheel is particularly useful in DC locomotive applications with individual axle control.

  • Patent number: 8970377
    Abstract: An item tracking system includes a plurality of items for storage and removal from a compartment. The system includes tags affixed to the items and configured to store identifiers for the items. A tag reader receives data from the tags in response to the items being removed from and returned to the compartment. A sensor in the compartment identifies a state change associated with the compartment. A processor identifies removal of an item with data received by the tag reader, identifies the state change with the sensor after the item is removed and before it is returned, and generates an output with an output device including the identifier corresponding to the item in response to the state change in the compartment.

    Abstract: An impact detection device for detecting impacts to a body part of a user and various supporting systems are discussed. In an example, an impact detect device can include a circuit board, a component having a first section and a second section, a battery, and a molding for housing the circuit boat, the battery and the component. The circuit board can include impact detection circuitry including at least two sensors and a communication circuit. A zone of reduced rigidity can connect the first and second sections of the component, with the circuit board secured to the first section. The battery can be secured to the second section of the component allowing for flex relative to the circuit board. The molding can be shaped and dimensioned for mounting to a body part of the user.

  • Patent number: 8940586
    Abstract: The present disclosure relates to a bump processing method and/or resulting MEMS-CMOS structure, in which one or more anti-stiction bumps are formed within a substrate prior to the formation of a cavity in which the one or more anti-stiction bumps reside. By forming the one or more anti-stiction bumps prior to a cavity, the sidewall angle and the top critical dimension (i.e., surface area) of the one or more anti-stiction bumps are reduced. The reduction in sidewall angle and critical dimension reduces stiction between a substrate and a moveable part of a MEMS device. By reducing the size of the anti-stiction bumps through a processing sequence change, lithographic problems such as reduction of the lithographic processing window and bump photoresist collapse are avoided.

  • Patent number: 8942950
    Abstract: A motion detection device includes: an acceleration detection unit, a separating unit, a gravity axis determination unit, and a motion detection unit. The acceleration detection unit detects acceleration components of each axis of a three-dimensional rectangular coordinate system of acceleration acting on the acceleration detection unit and outputs sets of acceleration component data. The separating unit separates the outputted sets of acceleration component data into stationary components and motion components. The gravity axis determination unit determines an axis whose separated stationary component is the largest to be a gravity axis. The motion detection unit detects, if an axis corresponding to a largest motion component showing a largest value of the separated motion components is an axis other than the determined gravity axis, a motion axis of the acceleration detection unit on the basis of the largest motion component.

  • Patent number: 8910522
    Abstract: A method for measuring positional changes of an object, including rotation about any or all of three axes, using linear accelerometers. There is disclosed a method of using a linear accelerometer to integrate two 3D linear accelerometers in order to measure and supply for further use six-dimensional information, that is, translation in three dimensions and rotation about three axes. Two linear accelerometer sensors are used to determine all but rotation about an imaginary axis between the accelerometers. Output from a third accelerometer may be used to generate the data needed to determine rotation about the imaginary axis. The need for a gyroscope for detecting changes in heading (i.e., yaw or azimuth) may therefore be avoided.
