    Abstract: A stress sensor includes a semiconductor substrate with a first transistor arrangement and a second transistor arrangement. The first transistor arrangement includes a first transistor with a first source-drain channel region and a second transistor with a second source-drain channel region. The first transistor and the second transistor are aligned relative to each other such that the current flow directions in the first and the second source-drain channel regions are opposite to each other. The second transistor arrangement includes a third transistor with a third source-drain channel region and a fourth transistor with a fourth source-drain channel region. The third transistor and the fourth transistor are aligned relative to each other such that the current flow directions in the third and the fourth source-drain channel regions are opposite to each other. The stress sensor generates a gradient-compensated output signal used to determine a mechanical stress acting on the semiconductor substrate.

    Abstract: A two-dimensional force sensor for measuring a first force in a first direction and a second force in a second direction. The sensor comprises a first resilient plate oriented in the second direction, a first end of the first resilient plate being arranged for being coupled to a reference point; a second resilient plate oriented in the first direction, a first end of the second resilient plate coupled to a second end of the first resilient plate and a measurement probe coupled to a second end of the second resilient plate. The measurement probe is mounted on an extension device mounted to the second end of the second resilient plate. The extension device positions the measurement probe at a position deviating from an imaginary cross-section point of the first resilient plate and the second resilient plate by no more than 20% of a length of the extension device.

    Abstract: The technology relates to a memory insertion machine for inserting memory modules into memory sockets on a circuit board. The memory insertion machine may include one or more insertion rods moveably mounted to one or more vertical guides and an insertion controller. The insertion controller may be configured to apply an insertion force to a memory module in a memory socket by controlling the movement of the one or more insertion rods on the one or more vertical guides. The movement of the one or more insertion rods may have a gradually decreasing deceleration as the insertion rods move towards the memory socket.

    Abstract: A method for identifying optimal locations for strain gage placement on a structure includes: providing a finite element (FE) model of the structure with an initial number I of candidate strain gage locations; conducting FE analysis to produce a strain matrix [S] of strain predictions, based on a load matrix [L] of external loads being applied to the FE model; relating the matrices to each other in a linear relationship model [L]=[S][β] having a residual error function; and reducing the initial number of the candidate locations to a reduced number by using a feature selection algorithm which minimizes the residual error function until a predetermined fidelity is achieved, resulting in a subset of the coefficients in the coefficients matrix [β] being zero and a remainder of the coefficients being non-zero, wherein the non-zero coefficients correspond to respective strain matrix columns and to the reduced number of candidate locations.

    Abstract: A head-mounted device may have a display with pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens assembly that includes a left lens and a first pixel array. A right positioner may be used to position a right lens assembly that includes a right lens and a second pixel array. Control circuitry may adjust the positions of the left and right lens assemblies using interpupillary distance information. Sensing circuitry such as force sensing circuitry may be used to ensure that the lens assemblies do not apply excessive force on a nose. Force sensors may be included between the lens assemblies and the nose, such as in, on, or adjacent to a nasal flap, or may be coupled to the lens assemblies.
