Abstract: Described are systems/devices and methods for measuring distances using a laser distance meter. The device may include a range finder measuring a distance; and a processor receiving the distance from the range finder and performing a calculation based on the distance. The method may include steps of determining, using a range finder included in a mobile device, a distance; and calculating, using a processor of the mobile device, one of an area and a volume based on the distance.

Abstract: Described are a method and a system for a wireless headset receptacle. The method includes a step of detecting one of a presence and an absence of a wireless receiver from a receptacle within a communication device. The wireless receiver includes a power supply and an interface for wireless communication with the communication device. The method also includes a step of performing at least one action based on one of the detected presence and the detected absence of the wireless receiver from the receptacle.

Abstract: Described is a device and system for heating an electronic mobile device. The system includes a mobile electronic device including a power supply arrangement and a removable heating arrangement detachably coupled to the mobile electronic device. When the heating arrangement is coupled to the mobile electronic device, the arrangement draws power from the power supply arrangement to generate heat.

Abstract: Described are a device and method for detecting ambient light. The device comprises a processing unit, a memory arrangement and a camera port. The memory arrangement stores setting data which includes a plurality of ambient light levels and a setting of a component of the device corresponding to each level. The camera port is configured to receive first data in a first format from a camera-type arrangement. When the camera port receives from a non-camera type data acquisition device second data in a second format, the processing unit converts the second data into further second data stored in the first format. The processing unit determines an ambient light level as a function of the further second data and adjusts the setting of the component as a function of the ambient light level and the setting data.
