Abstract: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Abstract: A waste suctioning and surface disinfecting device for cleaning up after pets includes a vacuum module and a disinfectant module, which are attached to and positioned in a housing. A suction hose and a fluid hose are attached to the vacuum module and the disinfectant module, respectively, and extend from the housing. First and second switches are attached to the suction hose and the fluid hose, respectively, and are operationally engaged to the vacuum module and to the disinfectant module, respectively. The disinfectant module can selectively dispense a disinfectant solution. The suction hose can be grasped in a hand of a user and the first switch selectively switched to actuate the vacuum module to suction up waste on a surface. Similarly, the fluid hose is used to disinfect the surface.

Abstract: An apparatus is disclosed for delivering vaporised chemicals into the atmosphere. In one embodiment the device comprises a light bulb with a glass casing and a region of sinter glass. Alternative embodiments are disclosed in which the device comprises a retainer adapted to retain chemical carrying elements and fixing means adapted to secure the element to the heat source including low energy light bulbs. The chemical carrying element is preferably a sintered ceramic. The sintered ceramic preferably has a homogeneous particle and pore distribution and may be nanoporous.
