Abstract: A shutter output portion is engaged with a shutter input portion of a developer container and supported to be displaced between an opening position and a closing position. The shutter output portion, when located at the opening position, opens a shutter of the developer container, and when located at the closing position, closes the shutter. A main interlocking mechanism causes the shutter output portion to move in conjunction with opening and closing operation of the cover portion such that the shutter output portion is displaced to the opening position when the cover portion is closed, and to the closing position when the cover portion is opened. The main interlocking mechanism includes a switch mechanism that releases an interlock between the shutter output portion and the closing operation of the cover portion in accordance with a release operation, and enables the interlock in accordance with an enabling operation.

The first movable section has a first section, a second section that is farther from the swing axis than the first section, and a third section disposed between the first section and second section. A separation distance between the third section and the first dummy electrode is greater than a separation distance between the first section and the first detection electrode.
Abstract: A solid particle aerosol development device form fogs of solid (e.g., frozen) fountain solution particles that are charged, and brings the charged solid fountain solution particles into proximity of an electrostatic charged image pattern on a imaging member's charge retentive surface. The charged solid fountain solution particles bond to the charge retentive surface at the charged image pattern to develop that image into a fountain solution latent image. The solid particle aerosol development devices produce solid fountain solution particles to develop electrostatic latent images while mitigating issues of evaporation and vapor production, and thus may apply fine films of fountain solution which may otherwise evaporate. In examples, the fountain solution aerosol development devices may include an anilox member, a metering member in contact with the anilox member, a fountain solution reservoir, a particle charger and a particle delivery baffle.
Abstract: Systems, methods, and devices are provided for aligning a reference axis of an accelerometer with a measurement axis of a machinery component. An adaptor including a mounting plate, a plate stud integrated within the mounting plate, and a screw can be coupled to an accelerometer to ensure proper alignment of the reference axis of the accelerometer with the measurement axis of the machinery component. Aligning the reference axis and the measurement axis using the adaptor ensures that the axial orientation of the vibration data collected by the accelerometer properly corresponds to the intended axis of measurement of the machinery component and thus allows for consistent, repeatable installations of the accelerometer onto the machinery component without introducing alignment errors which can generate erroneous vibration data with respect to one or more axes of measurement.

Abstract: According to some aspects of the subject technology, an apparatus includes an accelerometer including one or more sense electrodes to sense an input acceleration, and an unstick device to free the accelerometer from a stuck state due to a saturating acceleration input. The unstick device includes at least one unstick electrode and a control circuitry to cause the unstick electrode to generate vibrational energy to free the accelerometer.
Abstract: A method for reducing bias drift in electrical-mechanical systems sensor such as an accelerometer is provided. The method includes the steps of arranging at least one accelerometer in a chamber and initiating a plurality of temperature cycle sets. Each temperature cycle set has a minimum temperature, a maximum temperature, and a ramp rate. The conditioning method monitors the accelerometers until a bias drift is stabilized within a desired bias drift range. The minimum temperature and the maximum temperature limit a temperature range in which the accelerometer is cycled. Use of temperature limiting can quickly accelerate stabilization of the bias drift while also reducing degradation.
