Abstract: Various arrangements for using a positioning tag to facilitate control of a smart home device are presented herein. A communication sessions can be established between a control device and a positioning tag via a first device-to-device communication protocol. In response to a trigger event indicative of a user desiring to control the separate smart home device being detected, a positioning enablement message can be transmitted to the positioning tag via the first device-to-device communication protocol. A signal used for positioning is transmitted by the positioning tag using a second device-to-device communication protocol. Based on the received signal via the second device-to-device communication protocol, an interface that controls the smart home device is activated.

Abstract: A method for making a container includes forming a first cavity of a container by shaping an inner wall so that a first surface of the inner wall defines the first cavity; forming a second cavity of the container by shaping an outer wall so that a third surface of the outer wall surrounds a second surface of the inner wall such that together the third and second surfaces define the second cavity; and connecting the inner and outer walls together. The method then includes forming a hole through the outer wall to expose the second cavity to the outside ambient environment and then applying an enamel coating, while preventing the enamel coating from being deposited in the hole. After the enamel coating is applied, the method includes heating the container to glaze the enamel coating and fix the coating to the one or more surfaces.

Abstract: Educational book covers including a spine, a cover member, and a pull mechanism. The cover member pivotally couples to the spine. The cover member has an outer face. The pull mechanism is attached to the outer face. The pull mechanism includes a track and a knob. The track is coupled to the outer face. The track defines fixed pull positions along the length of the track. The knob is complementarily configured with the track to selectively rest within the fixed pull positions. The cover member includes unique indicia aligned with each fixed pull position to identify and differentiate the fixed pull positions for educational purposes. More force is required to pivot the cover member relative to the spine by pulling the knob when the knob is selectively translated within the track closer to the spine than when the knob is selectively translated within the track farther from the spine.
