  • Patent number: 9788155
    Abstract: A location aware user interface on a wireless handset is described. The location aware user interface comprises a location module configured to transmit a location message to a remote server via a network. The remote server is configured to determine whether the wireless handset is within a geofence. The user interface further comprises a display module configured to display at least one content item associated with the geofence. The user interface also comprises an input module configured to receive a user-created content item and transmit the received user-created content item to the remote server. The remote server is configured to associate the content item with the geofence in which the wireless handset is located.

  • Patent number: 9778305
    Abstract: A tire monitoring apparatus comprising a monitor installed on a tire and a pulse width measuring apparatus for measuring the width of pulses produced by the monitor. The pulse width measuring apparatus comprises a frequency analyzer for producing a frequency representation of the pulse, a signal processor for determining a minimum value of the frequency representation, and a pulse width estimator that inverts the minimum value to produce a measurement for the pulse width. The tire monitoring apparatus uses the pulse width measurement as an indication of characteristics of the tire.

  • Patent number: 9773020
    Abstract: A system and method for map based exploration is described. The system includes a dynamic graphical user interface (GUI) that includes a list of targeted content elements for each different group profile, in which a first dynamic GUI corresponding to a first group profile that is served to a first user is different from a second dynamic GUI corresponding to a second group profile is served to a second user at approximately the same location, when the group profiles are different. A map is displayed on the touch screen display and the map displays a plurality of geofences. A geofence selection received by the touch screen display presents the dynamic graphical user interface that includes the list of targeted content elements for the particular group profile associated with the particular wireless device at the geofence selection.

  • Publication number: 20170243314
    Abstract: Groups of users of a social networking system are categorized based on their association with a type of malicious activity. A set of predetermined malicious groups is identified. Users associated with the malicious groups are selected based on their level of interactions with the malicious groups. Other groups associated with the selected users are identified as being potentially malicious groups. The potentially malicious groups are further analyzed based on occurrences of keywords associated with the type of malicious activity and manual verification by experts. The potentially malicious groups are either classified as being malicious or non-malicious or assigned a score based on their likelihood of being associated with the type of malicious activity. The methods and system disclosed can be used for categorizing other types of social network objects based on their association with a type of malicious activity, for example, users, events, and content.

  • Patent number: 9688052
    Abstract: A thermal protection system that reduces a mismatch of thermal expansion coefficients CTE between a first material layer (CTE1) and a second material layer (CTE2) at a first layer-second layer interface. A portion of aluminum borosilicate (abs) or another suitable additive (add), whose CTE value, CTE(add), satisfies (CTE(add)?CTE1)(CTE(add)?CTE2)<0, is distributed with variable additive density, ?(z;add), in the first material layer and/or in the second material layer, with ?(z;add) near the materials interface being relatively high (alternatively, relatively low) and ?(z;add) in a region spaced apart from the interface being relatively low (alternatively, relatively high).

  • Publication number: 20170174014
    Abstract: A tire pressure monitoring system comprising a tire pressure monitoring device for mounting on an internal surface of a tire and including a pressure sensor for monitoring the fluid pressure in the tire. The system has an RFID tag located on the tire separately from the tire pressure monitoring device. In response to detecting a tire pressure event from monitoring the fluid pressure of said fluid, the tire pressure monitoring device causes the RFID to transmit data, which is received by the tire pressure monitoring device.
