A first service transmit signal in a first service can then be transmitted or received using the first antenna, and a second service receive signal in a second service can be transmitted or received using the second antenna and the diversity receiver. | 02-04-2016 |
20160080941 | METHOD AND APPARATUS THAT FACILITATES A WEARABLE IDENTITY MANAGER - Various aspects directed towards a wearable identity manager system are disclosed. In a first aspect, an association status between a user and a wearable identity manager device is ascertained based on whether the wearable identity manager device is worn by the user, and motion data associated with a movement of the wearable identity manager device is monitored. Authentication data, which includes the motion data, is then transmitted based on the association status. In another aspect, an association status between a user and a wearable identity manager device is again determined based on whether the wearable identity manager device is worn by the user. Here, however, the wearable identity manager device is paired with a pairing device, and authentication data is transmitted to the pairing device based on the association status to facilitate a user authentication via the pairing device. | 03-17-2016 |
