A battery charger for electric or hybrid motor vehicles having one container body installable on a motor vehicle and defining one housing compartment, one electronic appliance housed inside the housing compartment, connectable to one electric battery of the motor vehicle and configured to recharge the battery, one closing body of the container body associated in a removable manner with the latter to close the housing compartment, and the closing body being adapted to protect the electronic appliance housed inside the housing compartment whereby the closing body includes a reinforcing device/structure/component which are shaped and arranged so as to prevent the deformation of the closing body itself.

An electronic apparatus includes a housing with a power supply unit that receives external electrical power and supplies it to the apparatus using a power controller. The housing includes a heater; temperature and humidity sensors; and an electronic processor that receives power from the power supply unit and controls functions of the electronic apparatus. Upon startup, the power controller receives data from the temperature and humidity sensors; processes the received temperature and humidity data to indicate a current dew point within the housing; and compares the current dew point with a current location temperature at a location within the housing. If the current location temperature is at or below the current dew point, the heater is activated to raise the temperature within the housing. If the current location temperature is above the current dew point, electrical power supplied from the power supply unit to the electronic processor.

A miniaturized microsystem device including at least one of electrical, optical and mechanical components in a hermetically or non-hermetically sealed housing with respect to air humidity or encapsulated, which contains a desiccant. The humidity-dependent lifetime of the arrangement is determined by measuring the absorptivity of the desiccant.

A portable dehumidifying chamber includes a frame of a structure configured to include a first zone, a second zone, and a third zone, where a plurality of exterior walls coupled to the frame of the structure isolate the first zone, the second zone, and third zone from surrounding environmental conditions. A heating device disposed in the first zone to facilitate heated air flow from the first zone to the third zone, where the heated air flow contacts an object disposed in the second zone to facilitate dehumidification of the object. A conduit connecting the third zone to the first zone, where the conduit allows for humidified air flow to bypass the second zone, where the conduit includes a moisture removing apparatus. A first vapor barrier material separates the first zone and the second zone and a second vapor barrier material separates the second zone and the third zone.

A power electronics system comprising an environmentally sealed electronics compartment for housing power electronics equipment is provided. The system includes a heater configured to raise the air temperature inside the sealed electronics compartment, an internal environmental sensor for sensing conditions within the sealed electronics compartment, and providing environmental data, and an external environmental sensor for sensing conditions outside the sealed electronics compartment, and providing environmental data, and a controller. The controller is configured to receive environmental data from the internal environmental sensor, and the external environmental sensor, and control the operation of the heater to maintain a set humidity level. The system further includes a passive water vapor transport membrane placed in the walls of the sealed electronics compartment.

An environmental system protects internal components of a data center from condensation due to exposure to outside air. An environmental controller of the environmental system monitors sensor(s) that detect an outside temperature value and an outside humidity value of the outside air and an interior air temperature value of the data center. The environmental controller identifies an external access request to open an access door that exposes heat-generating IT component(s) within the data center to outside air. Based on the outside and the interior air temperature values and the outside humidity value received from sensor(s), the environmental controller determines that a dew point temperature of the outside air is greater than the interior air temperature. In response, the environmental controller increases a temperature set point of the cooling system to first temperature value that increases the interior air temperature above the dew point temperature of the outside air.

Aspects of the disclosure relate to reducing replacing a desiccant cartridge based upon a condensation risk. In one example, first information corresponding to a current dew point within a sensor housing of a sensor and second information identifying temperature data corresponding to a predefined area where the sensor is projected to travel may be received. Based upon the first and second information a condensation risk corresponding to the likelihood of condensation forming within the sensor housing in the event it traveled within the predefined area based upon the current dew point and the temperature data may be determined. Based upon the determined condensation risk, an indication that a desiccant cartridge within the sensor housing should be replaced to reduce the current dew point and the condensation risk may be provided.

A display module and an electrical equipment. The display module includes a display screen, a packaging structure and a heating layer. The packaging structure includes a packaging frame surrounding an edge of the display screen. The heating layer is between the packaging frame and the display screen.

A method for heating an electrical bus in an electrical cabinet containing at least one current conversion device includes determining a temperature inside of the electrical cabinet. The method also includes determining a temperature outside of the electrical cabinet. Further, the method includes applying heat to the electrical bus via conduction when the temperature outside of the electrical cabinet is below a predetermined temperature threshold or a difference between the temperature inside of the electrical cabinet and the temperature outside of the electrical cabinet is less than a desired temperature difference.
