  • Publication number: 20190106248
    Abstract: Various tamper-evident and/or tamper-resistant containers are disclosed. In some embodiments, the container comprises a base and a lid. The base can receive a food product. The lid can be engaged with the base to form a closed chamber in the container. In some embodiments, the lid is received in a peripheral channel in the base and/or recessed below an upper lip of the base to inhibit grasping of a peripheral edge of the lid. The lid can have a tab and a recess. The tab can be positioned in the recess. An indicator can overlay the tab in the recess. To open the container, the tab is drawn upward which pulls the lid out of engagement with the base. Removing the tab from the recess tears or otherwise mars the appearance of the indicator.

  • Patent number: 9946062
    Abstract: The embodiments described herein provide microelectromechanical system (MEMS) scanners with increased resistance to distortion in the mirror surface. Such MEMS scanners, when incorporated into laser scanning devices, are used to reflect laser light into a pattern of scan lines. Thus, by reducing distortion in the scanning surface these MEMS scanners can provide improved performance in scanning laser devices, including scanning laser projectors and laser depth scanners. In general, this is accomplished by providing a MEMS scanner where the connection to the scan plate is made at an intermediate support structure, and at a point on that intermediate support structure that is offset from the scanning surface. Providing the connection to the scan plate at points offset from the scanning surface can reduce the distortion that occurs in the scanning surface as a result of rotational forces in the MEMS scanner.

  • Patent number: 9759909
    Abstract: Scanning platforms for use in scanning laser devices are described herein. These scanning platforms are particularly applicable to scanning laser devices that use microelectromechanical system (MEMS) structures to facilitate mirror motion. The scanning platforms include a centrally located stationary mount portion and a movable portion that surrounds the stationary portion. The movable portion is configured to be coupled to a mirror and to facilitate motion of that mirror. Such a scanning platform can facilitate reduced size in scanning mirror assembly, and thus can facilitate a more compact scanning laser device.

  • Patent number: 9223129
    Abstract: A microelectromechanical systems (MEMS) device includes a scanning platform suspended from a fixed platform by two flexures that form a pivot axis. The two flexures may be symmetric or asymmetric about a centerline of the scanning platform. At least one flexure includes two segments that are not parallel to each other. A second flexure may include two segments with one segment being wider than the other. Flexure design reduces effects of mounting and thermal stresses when the MEMS device is mounted as part of an assembly.

  • Patent number: 9105834
    Abstract: A piezoelectric actuated device includes one or more areas of piezoelectric material coupled to a substrate. The piezoelectric material may be placed on regions of the substrate that exhibit the greatest curvature and stress when the device is vibrating according to a desired structural Eigenmode of vibration. The piezoelectric material may have a non-uniform density.

  • Patent number: 8559086
    Abstract: Briefly, in accordance with one or more embodiments, a piezoresistive stress sensor comprises a plurality of piezoresistive elements coupled in a bridge circuit disposed on, near, or contiguous to a flexure to detect torsional flexing about an axis of the flexure. The bridge circuit has at least two nodes disposed along the axis of the flexure and at least two nodes disposed off the axis of the flexure to maximize, or nearly maximize, an output of the bridge circuit in response to the torsional flexing of the flexure. A torsional flexing component of the output signal of the bridge circuit is relatively increased with respect to a component of the output signal generated by non-torsional stress of the flexure, or a component of the output signal generated by non-torsional stress of the flexure is reduced with respect to the torsional flexing component of the output signal, or combinations thereof.

  • Patent number: 8488224
    Abstract: Briefly, in accordance with one or more embodiments, an electric comb drive scanner comprises a scanning body comprising a mirror supported by one or more flexures along a first axis and one or more support structures coupled to the one or more flexures. One or more drive combs are disposed on the one or more support structures, wherein the drive combs cause the mirror to rotate about the first axis in response to a drive signal applied to the drive combs. The one or more support structures are tuned to reduce non-uniformity of warping of the support structures to reduce variation in disengagement of the drive combs along a length of the drive combs.

  • Patent number: 8437065
    Abstract: Briefly, in accordance with one or more embodiments, a scanning platform to scan a beam as a projected image comprises a frame and a scanning mirror supported by a flexure coupled to the frame of the scanning platform. The flexure has an asymmetric structure comprising a longer flexure arm and a shorter flexure arm to locate the scanning mirror at a position offset from a center of the frame. The resonant frequency of oscillation of the scanning mirror may be maintained or otherwise determined by selecting an appropriate cross-sectional area of the longer flexure arm or the shorter flexure arm, or combinations thereof.
