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, the concentration of the liquid desiccant may be dynamically changed based on changes within the system. 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. 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.

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.
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 circuit board comprising a processor to execute machine readable instructions and control operation of the device and a computer readable medium to store the machine readable instructions, a flexible circuit connecting to a connector of the circuit board and to an electrical component of the device, a bracket, and a resilient gasket in physical contact with the bracket and connector and transferring pressure from the bracket to the flexible circuit at the connector, whereby the connection between the connector and flexible circuit is maintained during usage of the device.
Abstract:
A display frame for a communication device includes: a substantially planar body to receive a display panel for a screen of the device, plural clips positioned around a periphery of the body to engage at least one of a slot and lip of a housing of the device, and a cutout to pass a flexible circuit extending from a printed circuit board and to the display panel, thereby enabling the flexible circuit to bend to connect to the display panel.

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.
