  • Patent number: 10824997
    Abstract: In some examples, a computing device may receive sensor data from sensors in a meeting room, determine that the meeting room is unoccupied, and indicate that the meeting room is unoccupied. The computing device may receive a request to reserve a current time slot of the meeting room and indicate that the meeting room is occupied. The computing device may determine that a meeting is scheduled to begin in the meeting room and place meeting-related devices, such as conferencing devices, in an operational state. The computing device may instruct a conferencing device in the meeting room to access a conference bridge. The computing device may determine a presence of individual meeting invitees in the meeting and display attendance data indicating invitees that are present and invitees that are absent from the meeting. The computing device may automatically send a reminder message to those that are absent.

  • Publication number: 20110219508
    Abstract: Described herein is an apparatus for securing eyewear to headwear. The apparatus includes a plurality of patches. Each of the plurality of patches comprise an elastomeric polymer configured to frictionally cling to a stem of the eyewear when the stem of the eyewear is placed on or over the surface. At least a first patch of the plurality of patches is disposed on a first outer side of the headwear and at least a second patch of the plurality of patches is disposed on a second outer side of the headwear. An adhesive is disposed at least partially on an underside of each of the plurality of patches. The adhesive is configured to secure each of the plurality of patches to the at least the first outer side of the headwear and the second outer side of the headwear respectively.
