Abstract: Systems, methods, and devices of the various embodiments enable a full keyboard of characters, such as Latin-based characters, to fit on a small touchscreen display. In an embodiment, a keyboard may be displayed including a text entry area and six virtual buttons. As a user interacts with the displayed keyboard, event actions may be determined based on the current displayed keyboard, the user input action indications received, and the text entry area state. The determined event actions may include displaying further keyboards, generating characters, and/or outputting character strings, and the event actions may be executed to enable the user to control character entry on a touchscreen display.

Abstract: A heat pump including a fluid circuit and a control arrangement. The fluid circuit includes a first heat exchanger, a second heat exchanger, a third heat exchanger and a driver for driving fluid about the fluid circuit. The control arrangement has one or more modes of operation. The first heat exchanger is arranged to exchange heat between the fluid of the fluid circuit and further fluid. The control arrangement is configured to in at least one of the modes of operation control a flow control mechanism to control a flow rate of the further fluid of the first heat exchanger.
