Abstract: Methods, systems, apparatus, and computer-readable media (transitory or non-transitory) are described herein for inferring psychological states. In various examples, data indicative of a measured affect of an individual may be processed using a regression model to determine a coordinate in a continuous space. The continuous space may be indexed based on a plurality of discrete psychological labels. In a first context, the coordinate in the continuous space may be mapped to one of a first set of the discrete psychological labels associated with the first context. In a second context, the coordinate in the continuous space may be mapped to one of a second set of the discrete psychological labels associated with the second context.

Abstract: An example image forming apparatus includes a main body having a guide frame to guide a toner cartridge on a path for detachment and attachment, a sensor to sense a remaining toner level of the toner cartridge, and a shutter member disposed to move along the guide frame in association with the attachment and detachment of the toner cartridge. In response to separation of the toner cartridge from the guide frame, the shutter member is movable to a first position covering the sensor and, in response to the toner cartridge being mounted on the guide frame, the shutter member is movable to a second position to open the sensor.
