  • Patent number: 9965053
    Abstract: The disclosure relates to the technical field of capacitive touch panels and discloses a touchpen which may be used in mobile phones, computers and other devices with touch panels for writing characters, letters and other symbols. In particular it relates to a capacitive touchpen 10 for inputting information into an electronic device 1 through touching of a capacitive touch panel 30, the capacitive pen comprising an elongated body member 11 comprising a conductive part 13 and a tip 12 disposed at one end of the body member 11 having a contact surface 14 for contacting the capacitive touch panel 30. The conductive part 13 is configured such that the distortion of the touch panel's electrostatic field caused by the conductive part 13 when changing the position of the touchpen 10 in relation to the capacitive touch panel 30, when the contact surface is kept in contact with the touch panel 30, is sufficient to register a change in capacitance by the capacitive touch panel 30.

  • Patent number: 9781571
    Abstract: Systems and methods of registration of an anonymous tag having an owner with a location service include authenticating a tag sensor associated with the owner of the tag with the location service. The tag is placed within a defined transmission distance of the tag from the tag sensor associated with the owner. The tag is activated while it is within the defined distance from the tag sensor to initiate transmission of the self identification. The transmitted self identification is received at the tag sensor to detect the tag. It is determined that the detected tag is not yet registered with the location service and an identification of the tag and the owner is transmitted to the location service from the tag sensor to register the tag as belonging to the owner at the location service to limit registration of the tag at the location service.

  • Patent number: 9373009
    Abstract: Tags may be grouped into a tag cluster to be represented by a master tag. Tag transmission reports may be received from one or more tag readers that receive wireless transmissions from a plurality of tags. Tag IDs corresponding to each tag of the plurality of tags in the tag transmission reports may be determined. A plurality of the tag IDs may be grouped into a tag cluster and one of the tag IDs may be selected as a master tag ID to represent the tag cluster. A control command may be transmitted to each tag of the tag cluster except for the master tag. The control command may instruct each tag of the tag cluster except the master tag to stop broadcasting wireless transmissions. The tags in the tag cluster will be represented by the master tag.

  • Patent number: 9313740
    Abstract: Application instructions for a sub-system processing unit are received through an application programming interface (API). The application instructions control a sub-system processing unit to process wireless messages directed to a main processing unit. A message rule may be generated based on the received application instructions and predefined conditions and actions stored in the sub-system processing unit. Responsive to receiving the wireless messages from sensors and/or tags external to the wireless terminal, an action may be performed at the sub-system processing unit according to the generated message rule to control and/or reduce processing of the wireless messages by the main processing unit.

  • Publication number: 20160092705
    Abstract: Systems and methods for detecting unauthorized tags are provided. A tag transmission report is received from a tag reader that receives wireless transmissions from a plurality of tags. A tag ID is determined for each tag of the plurality of tags in the tag transmission report. The determined tag IDs are compared to association information indicating associations between tag IDs. A notification is generated responsive to a comparison indicating that ones of the plurality of tags are not associated with other tags of the plurality of tags.

  • Patent number: 9049559
    Abstract: Systems and methods of providing location information associated with moveable objects include receiving tag identification (ID) information reports from a plurality of tag sensors. A movable object associated with each of the ID information reports received from the tag sensors is identified. Location information associated with the movable objects is updated responsive to the received ID information reports to provide updated location information for the moveable objects and an owner associated with each of the movable objects is determined. Access to the location information associated with respective ones of the movable objects is allowed only to requestors authorized by the owner associated with the respective ones of the movable objects, wherein the tag sensors have not been provided notification of ID information associated with the movable objects or of the owners associated with the moveable objects.
