Abstract: An angular acceleration sensor includes a curved track having first and second metallic layers, and a spherical conductive ball provided within the track. The first metallic layer has a constant, uniform, width along a length of the track while the second metallic layer has a varying-width along the length of the track. An angular acceleration experienced by the spherical conductive ball is associated with a change in a capacitance between the spherical conductive ball and the curved track, which is uniquely associated with an external linear acceleration experienced by the sensor.

Abstract: An image forming apparatus includes a flag, a sensor, a loop controller, a detector, and an image controller. The flag is disposed between the first and second conveying units and moves when in contact with a recording material having a loop. A signal value output from the sensor varies per a flag position. The loop controller changes a recording material speed based on the signal value output. The detector detects the recording material or an image formed on the recording material and the image controller changes an image forming condition based on the detection. The detector includes first and second contacting members that move to nip the recording material. A position of the flag, for changing a signal value output from the sensor, is included in a range in which first and second contacting members are movable.

Abstract: The present invention extends adjustable keyboard components. A user can selectively adjust height, tilt, and other keyboard positioning aspects (e.g., pitch, tilt, roll, yaw etc.), to accommodate the specific preferences and/or physical or anatomical characteristics of the user. Keyboard adjustments can tailor a solid foundational position for the user's fingers and hands. The keyboard can include separate left and right modules. Adjustability and separability facilitate highly variable and independent movement of the user's left and right hands. Adjustments and re-adjustments allow a user to make a wide range of alterations to their typing position at any point in time based on circumstances and comfort. As such, adjustments and re-adjustments can (potentially significantly) reduce discomfort and/or injuries associated with repetitive motion.

Abstract: A significant reduction in extra-column band broadening can be achieved by decoupling the injection system from the main solvent flow line. In addition, by decoupling the injection system from the main solvent flow line, additional components (e.g., filters, valves, etc.) can be introduced into the chromatography system without increasing the negative band broadening effects. Systems and methods herein provide not only for such decoupling but also for filtering precipitates from the system. As a result, a larger volume of sample can be injected into the present systems without compromising separation yield. In addition, an increase the column loading per batch, an increase the overall yield of separations, and greater system efficiency (i.e., less time lost for cleaning and maintenance) can be realized.
