A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

Provided are a computer program product, moveable robot block, and method for a moveable robot block deployed to form a barrier and sense environmental conditions. A command is received to couple to a location in a coordinate system comprising the barrier formed of a plurality of moveable robot blocks. Movement motors are controlled to cause the moveable robot block to move to the location in the coordinate system to couple to the barrier according to the command. An environmental sensor senses an environmental condition related to water sensed external to the moveable robot block when the moveable robot block is coupled to the barrier. The environmental condition is transmitted to the assembly management system over the network.

A window locking apparatus includes a proximal cross brace, a distal cross brace, a first track brace, and a second track brace. The first track brace is positioned parallel to the second track brace. The proximal cross brace is perpendicularly positioned in between the first track brace and the second track brace. The distal cross brace is perpendicularly positioned in between the first track brace and the second track brace, wherein the proximal cross brace and the distal cross brace are positioned offset of each other. The proximal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The distal cross brace is rotatably connected to the first track brace and removably mounted to the second track brace. The removable connections of the second track brace allows the window locking apparatus to be installed or removed from a window.

The safety systems enhance the safety of confined spaces which can present a danger to human occupants who may become entrapped within the confined space during a dangerous condition. The safety systems are particularly useful with confined spaces having access openings and a door or other movable barrier for the access opening. The safety systems having movable safety gates proximate the access openings. The disclosed safety gates are movable from a closed position where the safety gate forms a physical barrier which inhibits human entry into the confined space to a safety position where the safety gate prevents the door from closing and entrapping a person within the confined space.
