Example implementations relate to modular keyboards. In an example, a modular keyboard can include a keyboard module including keys, where the keyboard module includes a plurality of locking mechanisms, and a lattice removably coupled by the plurality of locking mechanisms to the keyboard module, where the lattice comprises a keyboard overlay.

Modular keyboard

An example of a system includes a electronic device having a rechargeable battery, a charging module to charge the rechargeable battery and moveable between a retracted position and an extended position to provide a stand during charging of the rechargeable battery, and a communication module to wirelessly transfer and receive data during charging of the rechargeable battery. The example system also includes a charging mat to charge the rechargeable battery when the charging module is in the extended position and coupled to the charging mat and a docking module to wirelessly transfer data to and wirelessly receive data from the communication module of the electronic device.

In an example, a light blocker may comprise a bellow to extend from an outer edge of a key to an inner edge of a key window to span a key gap in between the key and the key window. The bellow may extend along a periphery of the key, and the bellow may block light originating from under the key from passing through the key gap.

Key light blockers with bellows

Examples disclosed herein provide an electronic device to allow wireless charging of the electronic device when it is operated in various operation modes. The electronic device can include a base member comprising a top surface and a bottom surface opposite the top surface and a display member rotatably connected to the base member. The electronic device can include a rechargeable battery and a receiver to wirelessly charge the rechargeable battery when the bottom surface of the base member is to be placed atop a transmitter. As an example, the bottom surface of the base member is to remain atop the transmitter while the electronic device is in different operation modes.

Electronic devices for wireless charging

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 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.
