Abstract:
A system and method recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. A foam media absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger, powered by a variety of power sources, adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.
Abstract:
A handheld computing device can include a substantially rectangular first screen having a front surface, a rear surface, and a beveled edge extending between the front and rear surfaces of the first screen and a substantially rectangular second screen rotatably connected to the first screen so that the device is foldable between an open position and a closed position, the second screen having a front surface, a rear surface, and a beveled edge extending between the front and rear surfaces of the second screen. When the device is in the closed position, the first and second screens are positioned back-to-back and the beveled edges of the first and second screens angle inwardly toward the other respective screen to provide an angled surface configured to facilitate opening the device.
Abstract:
A handheld communication device includes first and second screens, a hinge to rotate the first and second screens between open and closed positions, and a position sensor to determine the relative position of the first and second screens. The position sensor can be a Hall-Effect sensor.

Abstract:
A handheld computing device includes a screen to receive input from and provide graphical output to a user, a housing engaging a peripheral portion of the screen, a light source, at least one light guide to receive incident light from the light source and direct the incident light to the screen to illuminate a portion of the screen, and a light guide bracket to engage the housing and the at least one light guide, the light guide bracket maintaining a position and orientation of the light guide relative to the light source.
Abstract:
A housing for a handheld computing device can include an outer shell having a base and a sidewall connected to a periphery of the base, the sidewall having a port configured to receive a button and the outer shell having an inner surface and an outer surface and a backing plate connected to the inner surface of the outer shell, the backing plate having a front edge and a rear edge, the front edge being positioned a predetermined height above the base, the rear edge being positioned adjacent to the base, the backing plate being positioned adjacent to the sidewall having the port and spaced apart from the sidewall by a predetermined distance to provide rigidity to the button and to define a datum for positioning a component within the housing.
Abstract:
A system and method to recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. Fans, valves, and manifolds are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. The airflow within the chamber and/or each tray is altered depending upon the settings of configurable airflow manifolds. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.

A foam media element in each tray absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and control device operation. The desiccant trays may be selectively configurable in an array to best suit the intended installation. The trays may be arranged in column and row configurations, along with adjustable airflow patterns between each of the trays. User interfaces are provided to monitor and control operation of the device.
