The preset invention relates to a gate with a crash-down prevention mechanism, comprising a gate panel which can be opened and closed by the rotation of a gate panel drive, a motor which is coupled to the gate panel drive, and a braking assembly with which opening and/or closing the gate panel can be decelerated, and a first measuring device for determining at least one movement parameter of the gate panel. In order to improve such a gate to the extent that a crash down of the gate can be reliably detected, and a braking assembly which brakes the gate quickly and avoids damage to the gate is triggered just as reliably, it is proposed to provide a second measuring device for determining at least one movement parameter of the motor, and a comparator which compares the measured movement parameters of the gate panel and the motor and triggers the braking assembly when the measured movement parameters of the gate panel and the motor fall outside of a defined relationship to each other.

To allow more daylighting and protect against direct solar radiation, the system may include a window shading system that impacts an area (or area of interest). The system may adjust different window shades in different ways and for different periods of time to protect against a direct solar radiation onto an area of interest. The system may provide targeted shadows onto the area of interest. The system may also analyze or predict angles of solar rays that comprise the direct solar radiation and determine an impact of the solar rays on the area of interest, wherein the adjusting of window shades is based on the determining.

The present invention relates to a hydraulic door drive for a lifting door (1) that opens, in particular, vertically, comprising at least one hydraulic motor (6), adapted and configured to drive a door curtain (2) or to be at least concomitantly driven by the door curtain (2), at least one hydraulic unit (10) for supplying the hydraulic door drive (5) with pressurized hydraulic fluid (13; 13a), characterized by a pressure accumulator (22), wherein a) potential energy of the door curtain (2), which is released when the latter is closed, can be stored in the form of pressure energy in the pressure accumulator (22), and/or b) the pressure accumulator (22) can be loaded with pressure energy by means of the at least one hydraulic unit (10), wherein c) pressure energy stored in the pressure accumulator (22) can be discharged to the hydraulic motor (6) in order to at least open and/or at least close the door curtain (2).

Methods and apparatus to monitor and/or adjust operations of doors are disclosed. An apparatus includes processor circuitry to execute instructions to: monitor a position of a door panel associated with a door system; detect when a beam from a photo-eye sensor associated with the door system is in an unexpected non-triggered state based on the position of the door panel; and generate an alert or notification indicating a significance of the beam in the unexpected non-triggered state.

Methods and apparatus to adjust door operations in response to surface pressure loads are disclosed. An apparatus includes sensor feedback analyzer circuitry to detect a surface pressure load acting on a door based on feedback from a sensor. The door includes a panel to move along a track. The apparatus also includes operations controller circuitry to control operations of the door. The operations controller circuitry is to automatically adjust an operation of the door in response to detection of the surface pressure load.

A storage system is disclosed where goods can be stored in containers and the containers are stored in stacks. Above the stacks runs a grid network of rails (e.g., tracks) on which load handling devices can run. To take containers from the stacks and deposit then at alternative locations in the stacks or deposit then at stations where goods may be picked. The framework may be provided with one or more of the following exemplary services: power, power control, heating, lighting, cooling, sensors, and data logging devices. The provision of these services within the framework rather than across the system as a whole, can allow for flexibility in storage whilst reducing cost and inefficiency.

A motor-operated drive system for a window covering system including a headrail, a mechanism associated with the headrail to spread and retract the window covering, and a continuous cord loop extending below the headrail for actuating the mechanism to spread and retract the window covering. The drive system includes a motor, a driven wheel that engages and advances the continuous cord loop, and a coupling mechanism for coupling the driven wheel to a rotating output shaft of the motor for rotation of the driven wheel. The drive system includes a channel system for redirecting the continuous cord loop engaged by the driven wheel, or other mechanism for configuring the drive system so that continuous cord loop extends in a substantially vertical orientation. The coupling mechanism includes an engaged configuration in which rotation of the output shaft of the motor causes rotation of the driven wheel, and a disengaged configuration.

Certain example embodiments relate to electric-potential driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter. The shutter includes a resilient polymer, a conductor, and optional ink. If shutter coil skew is detected, voltage(s) may be applied one or more areas of the on-glass transparent conductor to compensate for or otherwise attempt to correct the detected coil skew.
