| 20090036119 | Method and System for a Wireless Headset Receptacle - 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. | 02-05-2009 |
| 20090079954 | Method and Device for Measuring Distances - 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. | 03-26-2009 |
