Abstract: The various implementations described herein include methods and systems for using hand gestures detected at a wearable device to navigate a user interface. An example method includes receiving, via one or more neuromuscular-signal sensors of a wrist-wearable device worn by a user, data generated during performance of an in-air wrist movement by a wrist of the user. The method also includes moving a point of focus on the user interface in accordance with the in-air wrist movement; and receiving, via the one or more neuromuscular-signal sensors, additional data generated during performance of an in-air gesture by the user. The method further includes determining that the in-air gesture is an execution gesture; and executing a command corresponding to the execution gesture.

Abstract: Systems and methods are provided for using a gesture detected at a wrist-wearable device to cause presentation of camera data at a head-wearable device. One example method includes receiving, via one or more sensors of a wrist-wearable device worn by a user, data generated based on performance of an in-air hand gesture by the user. In accordance with a determination that the data indicates that the in-air hand gesture is a camera-control gesture, the method further includes causing presentation to the user, via a display of a head-wearable device that is worn by the user and that is in communication with the wrist-wearable device, of a representation of camera data from a camera that is in communication with one or both of the wrist-wearable device and the head-wearable device.

Abstract: For detecting a blocker RFID tag, the following steps are conducted. First, a random identifier of a given bit length is created. Alternatively, an identifier is selected out of a probing set, which is stored on a data storage device. The probing set comprises of identifiers, which are not being used as identifiers for a given set of RFID tags. In a second step, a response from all RFID tags is requested having an identifier matching the random identifier or, respectively, the selected identifier. In a third step, it is determined, depending on receiving or not receiving a response, whether the blocker RFID tag is present.

Abstract: For detecting an invalid RFID tag, an identifier and authentication information is read from a given RFID tag. The authentication information is then verified dependent on at least a given part (IDP_TAG) of the identifier (ID_TAG) and it is determined that the given RFID tag is the invalid RFID tag if the verification was negative. Accordingly, an RFID tag is manufactured by determining an identifier (ID), determining an authentication information dependent on at least a given part (IDP) of the identifier (ID) and storing the identifier (ID) and the authentication information on or in the RFID tag.

Abstract: A method of establishing a trustworthiness level of a participant in a communication connection between a first communication partner and a second communication partner is proposed whereby the communication behavior is adapted to the established trustworthiness level. The participant is equipped with a trustworthiness certificate and a therefrom separated securely stored participant private key. The first communication partner receives the trustworthiness certificate from the participant wherefrom the trustworthiness level is derived and established. The first communication partner tests whether the trustworthiness certificate belongs to the participant by using the participant private key. In case the trustworthiness certificate is confirmed by the test to belong to the participant, the first communication partner communicates the established trustworthiness level to the second communication partner.

Abstract: A method of transmitting information data from a sender to a receiver via a transcoder is proposed. The information data comprises confidential information data which is encrypted and non-confidential information data. Security information and transcoding-type information is sent together with the partly encrypted information data to the transcoder which uses the security information and transcoding-type information during a transcoding step. The encrypted confidential information data is thereby transcoded without using its content while the non-confidential information data is transcoded, having access to its content.
