Abstract: A wearable device includes a processor in electrical communication with a non-transitory computer-readable storage medium storing a plurality of messages, an actuator, an audio transducer, and a light emitter. Responsive to the actuator receiving a user input, the processor retrieves a message of the plurality of messages from the storage medium, illuminates the light emitter with a color corresponding to a theme associated with the retrieved message, and plays the message via the audio transducer.

Abstract: Aspects extend to devices that facilitate positioning components in a rack to permit base plane access. In one aspect, a drive carrier rail is configured to have variable widths to facilitate positioning a drive carrier in a fixed position within a slot (of a rack) where a drive is disengaged from the base plane printed circuit board (PCB). In another aspect, at least one slot rail of a slot includes a (e.g., sheet metal) spring. The spring allows a drive carrier to rest on the spring in a fixed position where the hard drive is disengaged from the base plane printed circuit board.
