The invention provides techniques for thinning halftone dots in a halftone dot bit map. Reducing the strain in the light emitting device may improve the performance of the device. A battery case has an open surface and is stored within the case storage section, wherein the open surface of the battery case is oriented in the same direction as the open surface of the case storage section. The profile associated with the individual is then reviewed to determine one or more contact identifiers associated with the selected communication type.
