Abstract: A system for delivering an implant device to a vascular site in a patient a delivery pusher apparatus, an implant device detachably connected to the delivery pusher apparatus by a tether having a distal end connected to a proximal end of the implant device, wherein the tether is substantially non-tensioned when connecting the implant device to the delivery pusher, and an electrical heating element configured coaxially around at least a portion of the tether, wherein heat generated by the heating element severs the tether at a point near the proximal end of the implant device.

Abstract: A command to update a volume level of a group comprising a first and a second playback device to a requested group volume level is detected, the requested group volume level indicating respective requested volume levels for the first and second playback devices. Based on the command, (i) a first volume state variable of the first playback device is determined to be adjusted based on a first maximum volume state variable and (ii) a second volume state variable of the second playback device is determined to be adjusted based on a second maximum volume state variable. Based on the first and second maximum volume state variables, the volume level of the playback group is adjusted to an alternate group volume level different from the requested group volume level. An indication that the volume level of the playback group has been adjusted to the requested group volume level is provided.

Abstract: An insulated fireproof concrete form system. The system includes a pair of autoclaved aerated concrete blocks oriented parallel to each other. A pair of insulating blocks are disposed on a pair of internal surfaces of the pair of autoclaved aerated concrete blocks. The pair of insulating blocks are horizontally staggered relative to the pair of autoclaved aerated concrete blocks. A plurality of rods connects the pair of autoclaved aerated concrete blocks.

Abstract: A dental instrument having a first member with an axial passage engageable with a removable second member. Rotationally engageable dental tools engageable at a first end of the first member, are fixed in a radial position around their axle by the distal end of the second member engaged within the axial passage. The dental instrument allows for the tools to be from a kit featuring a plurality of different tools, each of which is engageable to the axle, and rotatably adjustable for holding in a fixed position by the second member.
