Abstract: Methods and systems for calibrating a transmission electron microscope are disclosed. A fiducial mark on the sample holder is used to identify known reference points so that a current collection area and a through-hole on the sample holder can be located. A plurality of beam current and beam area measurements are taken, and calibration tables are extrapolated from the measurements for a full range of microscope parameters. The calibration tables are then used to determine electron dose of a sample during an experiment at a given configuration.

Abstract: Example embodiments include an apparatus and a method for monitoring and reporting on HVAC performance. In an example method, an HVAC system is monitored to detect a plurality of sample intervals during which the HVAC system is active. The plurality of sample intervals may be, for example, a plurality of heating intervals and/or a plurality of cooling intervals. An ambient temperature or other environmental parameter is monitored to determine a change over each of the sample intervals. A sample value is determined for each of the sample intervals, each sample value representing a ratio between a duration of the interval and the temperature change over the course of the respective period. Statistics of the sample values are evaluated and may be used to identify changes in HVAC performance. Analogous methods preformed for periods of HVAC inactivity may be used to detect changes in heat retention performance.

Abstract: Aspects of the subject technology provide for secure, privacy-preserving access to electronic conferencing. In one or more implementations, a device may obtain a link that corresponds to a call with a second device, encrypt a request to join the call using a key obtained using the link, and send the encrypted request to a server for delivery to the second device. The link may also include information used to identify an alias for an account associated with the second device. The device may send the encrypted request to the server with the alias. The device may receive an encrypted response to the request from the server, obtain an identifier of the call from the encrypted response, and then receive an invitation to join the call associated with the identifier.

Abstract: A device includes an image capture device directed towards a user's eye and a dispensing mechanism configured to receive an apparatus containing fluid. The image capture device is coupled to a controller that processes images of the user's eye captured by the image capture device to determine when the user's eye has been open for at least a threshold amount of time. An orientation sensor included in the device determines an orientation relative to vertical of the device. When the controller determines that the user's eye has been open for at least a threshold amount of time and that the device has an orientation within a specific range, the dispensing mechanism applies force to the apparatus storing fluid to dispense fluid. One or more sensors in the device detect when fluid has been dispensed.

Abstract: An image processing system enables a user wearing a head-mounted display to experience a virtual environment combined with a representation of a real-world object. The image processing system receives a captured scene of a real-world environment that includes a target object. The image processing system identifies the target object in the captured scene and generates a representation of the target object. In some cases, the image processing system may include a graphical overlay with the representation of the target object. The image processing system can generate a combined scene that includes the target object and the virtual environment. The combined scene is presented to the user, thereby allowing the user to interact with the real-world target object (or a representation thereof) in combination with the virtual environment.

Abstract: Described herein are examples of a system that processes information describing movement of a vehicle at a time related to a potential collision to reliably determine whether a collision occurred and/or one or more characteristics of the collision. In response to obtaining information regarding a potential collision, data describing movement of the vehicle before and/or after a time associated with the potential collision is analyzed to determine whether the collision occurred and/or to determine one or more collision characteristic(s). The analysis may be carried out at least in part using a trained classifier that classifies the vehicle movement data into one or more classes, where at least some the classes are associated with whether a collision occurred and/or one or more characteristics of a collision. If a collision is determined to be likely, one or more actions may be triggered based on the characteristic(s) of the collision.
