A blinding arrangement for shielding a vehicle front windshield. The blinding arrangement includes at least one blinding system which includes a cassette, a spannable blinding body which can be moved out of and into the cassette, a horizontal upper guide rail for guiding the spannable blinding body in a horizontal direction, and a cassette locking arrangement. The horizontal upper guide rail is fixedly mounted above the vehicle front windscreen. The cassette pivots within a cassette pivot plane between a horizontal non-use position in which the cassette is arranged parallel to the horizontal upper guide rail and a lowered use position in which the cassette is arranged perpendicular to the horizontal upper guide rail. The cassette locking arrangement locks the cassette in the horizontal non-use position.

Provided is a self-generating smart glass, including: a window frame, an outer glass and an inner glass, a plurality of solar panels, a first electric telescopic rod, a plurality of slide grooves which are symmetrically arranged on a top and a bottom of the window frame, a foldable plate located between the outer glass and the inner glass, a first battery, a light sensor and a control system. Two adjacent outer surfaces of the foldable plate are provided with the solar panels which are connected in series through flexible wires and communicated with the first battery. The first electric telescopic rod, the light sensor and the control system are respectively connected to the power supply; and the first electric telescopic rod and the light sensor are respectively connected to the control system.

A top-down bottom-up window covering includes a first beam and a second beam, which are sequentially provided below a fixture, and a covering material connecting the first beam and the second beam. A first lifting structure is installed in the first beam, and a second lifting structure is installed in the second beam. The first lifting structure is adapted to operate as the first beam is being controlled to move toward or away from the fixture, and the second lifting structure is adapted to operate as the second beam is being controlled to move toward or away from the fixture. Whereby, the top-down bottom-up window covering can be easily assembled and maintained.

An automated fire or smoke curtain/blinds system (2) includes a pelmet or a hood (4) adapted to be mounted on a wall or top of a windowpane, at least one motor (6) connected to at least one curtain/blinds holding device (10) such that the curtain/blinds 5 holding device (10) rolls when the motor (6) is operated, at least two curtain/blinds holding device wherein each curtain/blinds holding device are connected by a shaft or ball bearing, a movable curtain or blind with width of at least 8 meters attached to at least two curtain/blinds holding device, a movable curtain or blind (14A) of a predefined width and at the end of which is a bottom rail (14B), wherein the movable 10 curtain (14A) includes an self-closing escape door (14C) embedded within coverage area of the movable curtain (14A), and a control panel (16) to control up/down movement of the movable curtains.

An actuation assembly for a continuous looped operator includes a slide assembly configured to laterally slide in a first direction and a second direction opposite the first direction, a first cord engagement member carried by the slide assembly, a second cord engagement member carried by the slide assembly, and a selector switch connected to the slide assembly, the selector switch receives a portion of the first cord engagement member and a portion of the second cord engagement member, the selector switch configured to move relative to the slide assembly between a first position and a second position.

The invention concerns a drilling device (1) and a method for drilling holes in a stack of material (100). The drilling device is provided with clamping means (23, 26) for clamping the material, a hollow drill (10) with an internal channel and a drive (3) for the hollow drill. The drilling device is further provided with connecting means (4) for cooling means, that are arranged for conducting gas through the internal channel, and suction means (51) for suctioning drilling debris. The drilling shaft is provided with a cut out, that runs in longitudinal direction along the drill shaft and forms a discharge channel for the drilling debris.

The invention also concerns a machine for machining and assembling window coverings, such as pleated blinds, comprising one or more drilling devices according to the invention.

A low-power radio-frequency (RF) receiver is characterized by a decreased current consumption over prior art RF receivers, such that the RF receiver may be used in control devices, such as battery-powered motorized window treatments and two-wire dimmer switches. The RF receiver uses an RF sub-sampling technique to check for the RF signals and then put the RF receiver to sleep for a sleep time that is longer than a packet length of a transmitted packet to thus conserve battery power and lengthen the lifetime of the batteries. The RF receiver compares detected RF energy to a detect threshold that may be increased to decrease the sensitivity of the RF receiver and increase the lifetime of the batteries. After detecting that an RF signal is being transmitted, the RF receiver is put to sleep for a snooze time period that is longer than the sleep time and just slightly shorter than the time between two consecutive transmitted packets to further conserve battery power.
