A swimming pool entrance opening warning device comprises at least one door magnetic switch, at least one bypass switch and a host, wherein the door magnetic switch is arranged on a door leading to the swimming pool entrance, the bypass switch is arranged on a building structure adjacent to the swimming pool entrance, the bypass switch being provided with a first release button, and the host is arranged on the building structure adjacent to the swimming pool entrance or the door, the host and the bypass switch be located at different positions, the host comprising a host shell, a speaker module arranged on the host shell, a second release button arranged on the host shell, and a control circuit board connected with the first release button and the second release button, while according to the invention, when the door is opened and two release buttons do not generate a release signal after passing a buffering time, the speaker module is actuated through the control circuit board, thereby preventing unauthorized personnel from entering and exiting the swimming pool.

A door closer diagnostics system including a door closer, a server, and a mobile device having a display and at least one sensor. The mobile device is configured to (i) generate, by the at least one sensor, motion data indicative of motion of the door as the door is moved from an open position to a closed position, and (ii) transmit the motion data to the server. The server is configured to analyze the motion data to (i) determine a duration the door was in each of a plurality of door movement zones between the open and closed positions, (ii) determine at least one adjustment to the door closer for a successful installation of the door closer based on the duration the door was in each of the door movement zones, and (iii) transmit at least one installation instruction corresponding with the at least one adjustment to the mobile device.

A snubber includes an engagement portion with a free end configured to be removably engaged within a groove in a frame. The engagement portion includes a first engagement member and a second engagement member at least partially separated from the first engagement member. The second engagement member deflecting less than the first engagement member when a negative pressure is applied to the sash.

A method for execution by a computing entity includes interpreting a fluid flow response from fluid flow sensors to produce a piston position of a piston associated with a head unit device. The head unit device includes a chamber filled with a shear thickening fluid (STF). The method further includes determining a door position based on the piston position. The method further includes determining parameters for wireless signals based on the door position. The method further includes facilitating utilization of the parameters for the wireless signals to promote successful communication of status and/or control of the door via the wireless signals.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
