Abstract: A server determines, during a conference implemented using conferencing software and based on stored data associated with two or more users participating in the conference, that the two or more users are accessing the conferencing software from separate user devices located in separate areas of an office premises. The server determines, by accessing stored conference room scheduling data of the office premises, that a conference room within the office premises is available for use by the two or more users. The server transmits, to each of the separate user devices, a prompt recommending that the two or more users further participate in the conference using a shared device configured to access the conferencing software within the conference room.

Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users.
