The invention belongs to the technical field of ships, and relates to an aerogel heat preservation ship rescue cabin, which comprises a cabin body. The cabin body and arc-shaped plates are made of aerogel materials. Water pumping devices are symmetrically sleeved outside the cabin body near two sides. A straight pipe is connected between the two water pumping devices. Strip-shaped water outlet holes are formed at front and rear sides of the straight pipe in a penetrating manner. A heat insulation plate is sleeved on the cabin body and hollow, and two ends thereof are communicated with the water outlet holes at front and rear sides of the straight pipe. Multiple drainage holes are formed in the inner wall, opposite to the cabin body, of the heat insulation plate in a penetrating manner. Multiple evaporation holes are formed in the top of the heat insulation plate in a penetrating manner.

Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

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.

The present invention describes a method for thermo-treatment of wood, where said method comprises the following steps: a) selecting the wood to be as free from knots as possible b) introducing the wood to a temperature increase up to approximately 173° C.; c) maintaining the wood at an ambient temperature of 173° C. for 3-5 hours; d) decreasing the temperature to approx. 20° C.; e) introducing the wood into an autoclave wherein a mixture of linseed oil and mineral oil is applied to the wood, and allowing the mixture to penetrate the wood f) retrieving and storing the treated wood. Furthermore a timber member made with wood treated according to the method is disclosed.

Intelligent building control systems utilize sky information from a camera or cameras to facilitate control of building systems such as lighting, motorized window coverings, electrochromic glazings, HVAC systems, and so forth. Based on the sky information, interior lighting intensity and/or color temperature may be modified, for example in order to achieve a desired circadian effect for building occupants. In this manner, energy efficiency and occupant comfort and convenience are improved.

Infrared cloud detector systems and methods for detecting cloud cover conditions.

An electric light and external light control system for a space with a dual-mode light sensor is proposed. The dual-mode light sensor (106) measures and computes the amount of external light and electrical light incident on its sensing surface. The individual measured light components (total light, electric light and external light) are transmitted to the window treatment controller (103) and the electric light controller (102). The controllers (102, 103) use this information to optimally control the lighting condition to meet user requirements and reduce energy consumption. Both controllers (102, 103) operate concurrently and independently, but are linked via the dual-mode sensor (106).

A mobile device that is configured for wireless communication may be configured to operate as a remote control device in a lighting control system, controlling one or more lighting control devices of the lighting control system. The remote control device may control the light intensity in a space, for instance at a location of the remote control device, in response to an ambient light intensity measured at the remote control device. The remote control device may define a user interface for receiving an input that indicates a desired light intensity at the location. The remote control device may measure the ambient light intensity at the location via a light detector, compare the measured ambient light intensity to the desired light intensity, and cause the one or more lighting control devices to adjust the ambient light intensity at the remote control device until it agrees with the desired light intensity.

Generally plano rectangular louvers are capable of being ganged in a stacked tiltable array to enhance light re-direction when titled to follow the solar elevation. Combinations of features and optical characteristic avoid optical artifacts and enhance efficiency of light utilization and manufacturing. Different louvers can be combined in alternative ways in such arrays.
