A dimmer mechanism is movable by a motor that is powered by solar-charged supercapacitors between a first configuration, in which the dimmer mechanism blocks little of the interior of a skylight tube to maximize light throughput into a room, and a second configuration, in which the dimmer mechanism blocks more of the interior of a skylight tube to reduce light throughput into the room.

A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, includes a fixed element anchorable to a stationary support structure and a mobile element anchorable to the closing element. The fixed and movable elements are mutually coupled so as to rotate with respect to each other between an open position and a closed position. One of the fixed or movable element includes a working chamber, with a plunger disposed to slide along a longitudinal axis and operatively coupled with the other one of the fixed or movable elements so that the sliding of the plunger corresponds to a rotation of the movable element.

A switched-mode light-emitting diode (LED) display unit satisfying fire-fighting smoke exhaust and ventilation requirements includes an LED display unit, a mounting member, an opening-closing actuator and a pressing member. The LED display unit is mounted on the mounting member and the mounting member is mounted on a display panel by an opening-closing actuator and pressed against the display panel by a pressing member. The switched-mode LED display unit provides the pressing member that works to release the pressed mounting member after obtaining a triggering command and the opening-closing actuator that turns on the LED display unit subsequently, thereby meeting the fire smoke exhaust ventilation requirement of the internal surface or the external surface of a building.

An apparatus includes a housing, a digital display device, at least one gate coupled to the housing, and an analytical unit comprising a controller, the analytical unit coupled to the digital display device and the controller. The analytical unit includes logic to operate environmental sensors to identify demographic attributes of a proximate person to the digital display device and to locate digital content associated with the demographic attributes and to cause display of the digital content on the digital display device.

The present invention relates to a removable pet door. The removable pet door comprising a lower wall section hingedly connected to an upper wall section. The present removable pet door addresses or ameliorates some of the issues encountered by presently available pet doors.

It is described herein a venting apparatus for an opening in a roof. The venting apparatus for an opening in a roof may comprise a structural frame, an adapter, a mount, a hinge, and a latch. The adapter may comprise a frame adapter section, a lip extending inwardly from a portion of the frame adapter section inner surface, and a protrusion extending upwardly from the lip. The frame adapter section may be configured to fit around an outer surface of the structural frame while the mount may be configured to fit around an outer surface of the protrusion. The latch may be configured to receive a signal from a device when the device detects the presence of smoke within the building to cause the latch to change from a latch closed position to a latch opened position.
