Abstract:
La présente invention consiste en un système de persiennes constitué de lames inclinées de façon à maximiser l'éclairement solaire direct reçu pendant les mois d'hiver et le minimiser pendant les mois d'été. Les inclinaisons sont définies en fonction de la latitude terrestre du bâtiment support à ces persiennes, et de l'orientation de la surface du bâtiment à protéger, en général un vitrage. L'inclinaison longitudinale des lames est définie telle que la direction longitudinale des lames soit sensiblement parallèle à la droite intersection du plan de la dite surface et du plan de l'équateur vu du dit bâtiment. L'inclinaison transverse des lames est définie telle que celles-ci visent dans une direction comprise entre 12° et 24° en dessous de la direction du plan de l'équateur.
Abstract:
A method comprises measuring a light intensity at a window; determining if the light intensity exceeds a cloudy-day threshold; operating in a sunlight penetration limiting mode to control the motorized window treatment to control the sunlight penetration distance in the space; enabling the sunlight penetration limiting mode if the light intensity is greater than the cloudy- day threshold; and disabling the sunlight penetration limiting mode if the total lighting intensity is less than the cloudy-day threshold. The cloudy-day threshold is maintained at a constant threshold if a calculated solar elevation angle is greater than a predetermined solar elevation angle, and the cloudy-day threshold varies with time if the calculated solar elevation angle is less than the predetermined solar elevation angle. The cloudy-day threshold is a function of the calculated solar elevation angle if the calculated solar elevation angle is less than the predetermined solar elevation angle.
Abstract:
Present invention refers to the blinds that are found in a closed space between two window panes (2; 3), and which are regulated by magnets from the outside, particularly to the guiding means between two window panes (2;3). Magnets are placed between window panes in the inner battens (4.1;7) while controlling battens (5; 6) are arranged from the outer side of the inner window pane (3) and serve for lifting or lowering of the blinds. At the end of the battens (5, 6, 7 and 4.1) are arranged end parts (4.2) and (5.6) containing magnets (8a, 8b, 18a and 18b). Each inner top/bottom contact magnets (8a; 18a) are fitted to be in the opposite magnet pole in relation to the poles of the external top/bottom contact magnets (8b; 18b) on the external top and bottom regulating batten (5; 6). Magnets hosed in the end parts (5.6) of the external battens (5; 6) attract magnets housed in the end parts (4.2) of the inside battens (7; 4.1). After installing the inner part of the blinds, the space between the window panes is permanently sealed from the environment. One of the characteristics of the invention is frame of the insulated window glass that consists of two pair of aluminum profiles where on the upper and lower end of the insulated window glass are arranged mutually opposed profiles (1.1) and laterally are arranged mutually opposed rails (1.2). Lateral rails (1.2) are designed in a manner that contain axle pin 4.4 that gets into keyway (4.5) positioned on contact surface of the end parts (4.2) whereby rails (1.2) have function of guides and spacers at the same time. By present technical solution, any contact of external/internal batten assembly and blinds (12) with the window glass is prevented thus preserving in good condition of applied Low-E coating on the any side of the window pane.
Abstract:
A blind system comprising a head-rail; a first cord mechanism associated with a first blind portion via a first cord; a second cord mechanism associated with a second blind portion via a second cord; each blind portion comprises a bottom rail; the first blind portion is interposed between the headrail and the second blind portion, wherein the second cord is also associated with the first blind portion.
Abstract:
The disclosure provides building elements for a building using solar energy for building heating and cooling. The building uses building elements are able to collect and store solar heat building and have a fluid channel that is arranged in said building element such that a fluid is able to absorb and transfer the absorbed solar heat. A solar heat storage device is connected to the fluid channel to store the heat for hot water and/or space heating and a solar heat radiator is connected to said fluid channel for cooling the building element. The building elements may further comprise one or more of automation control system, electric power pump, heat driven self-powered pump, solar cooking appliance or a solar heat appliance.
Abstract:
A window shade comprises a head rail, a shading structure, a bottom part, suspension cords connected with cord winding units, and a control module. The control module includes a drive axle assembled with the cord winding units, a sleeve affixed with the drive axle, an arrester assembled around the drive axle, and a release unit. The arrester has a locking state in which the arrester blocks a rotational displacement of the sleeve and the drive axle to keep the bottom part at a desired position, and an unlocking state in which rotation of the sleeve and the drive axle is allowed to lower the bottom part by gravity action. The release unit includes an actuator that is operatively connected with the arrester and has an elongated shape. The actuator can rotate about its lengthwise axis to turn the arrester from the locking to unlocking state.
Abstract:
A low-power radio - frequency (RF) receiver is characterized by a decreased current consumption 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.
Abstract:
A battery-powered motorized window treatment (310) for covering at least a portion of a window may be adjusted into a service position to allow for access to at least one battery (138) that is powering the motorized window treatment (310). A headrail of the motorized window treatment may be adjusted to the service position to allow for easy replacement of the batteries (138) without unmounting the headrail8114) and without requiring tools. The motorized window treatment (310) may comprise brackets (370) having buttons (372) that may be actuated to release the headrail (114) from a locked position, such that the headrail (114) may be rotated into the service position. The headrail (114) easily rotates through a controlled movement into the service position, such that a user only needs one free hand available to move the motorized window treatment (310) into the service position and change the batteries (138).
