  • Publication number: 20140370870
    Abstract: A mobile communication device and method of communication is disclosed. A communication signal having a message class is received at the mobile communication device conveyed by a vehicle. A message class of the received communication at the mobile communication device is obtained. A station of motion of the vehicle is determined at the mobile communication device.

  • Publication number: 20140342188
    Abstract: An apparatus includes a substrate and a magnetic layer coupled to the substrate. The magnetic layer includes an alloy that has magnetic hardness that is a function of the degree of chemical ordering of the alloy. The degree of chemical ordering of the alloy in a first portion of the magnetic layer is greater than the degree of chemical ordering of the alloy in a second portion of the magnetic layer, and the first portion of the magnetic layer is closer to the substrate than the second portion of the magnetic layer.

  • Publication number: 20140232698
    Abstract: Stylus-entered writing is converted into corresponding text and a control circuit then adjusts graphic embellishment of at least a first portion of that text as a function, at least in part, of detected user dynamics as regards user control of the stylus at a time that corresponds to the stylus-entered writing that corresponds to that first portion of the text. By one approach this adjustment reflects a comparison between those detected user dynamics and previously-stored user dynamics profile information. So configured, the resultant recognized text can, via the aforementioned graphic embellishment, convey emotional expression of the writer at the time of writing that text.

  • Patent number: 8809783
    Abstract: Systems, methods, and computer-readable media for temperature measurement of a sample, using new temperature measurement and mapping techniques, are provided. The technique employs a temperature sensitive electron signal in a scanning electron microscope (SEM) and provides both high spatial resolution and non-contact temperature measurement capabilities. An electron beam of the SEM can be initiated to interact with a sample, and a temperature sensitive signal can be collected from the sample and analyzed.

  • Publication number: 20140198080
    Abstract: A control circuit stores profiles of stylus-input user preferences and pre-associates individual ones of those profiles with corresponding different applications. Upon opening one of those applications the control circuit then automatically uses the corresponding pre-associated stylus-input user preferences. So configured, a user's specific preferences regarding how the control circuit will render electronic ink on a display in response to stylus-based input are automatically utilized on an application-by-application basis without requiring the user to access and change global settings for stylus input.

  • Publication number: 20140168012
    Abstract: Method, device and computer readable memory aspects describe aligning antennas such as short range communication antennas in communication devices that may be used to transmit and receive electrical power for device charging. A measure of antenna alignment may be determined in response to electrical power received by one of the antennas. A suggested movement is determined for moving at least one of the antennas (e.g. the communication device housing the antenna) for increasing the measure of antenna alignment and the suggested movement is presented in a graphical user interface (GUI). Movement may be suggested along a first plane to maximize antenna alignment followed by movement along a second plane to further maximize antenna alignment. A map may be defined from measured antenna alignment values and movement suggested in response to the map. Maximized antenna alignment may be signalled (e.g. vibration) when the measure of alignment is within a threshold range.

  • Publication number: 20130340127
    Abstract: Advantageous systems, methods, and computer-readable media for temperature measurement of a sample, using new temperature measurement and mapping techniques, are provided. The technique employs a temperature sensitive electron signal in a scanning electron microscope (SEM) and provides both high spatial resolution and non-contact temperature measurement capabilities no existing technique can adequately combine. This technique thus adds a new capability—temperature measurement and mapping—to the collection of existing SEM capabilities.

  • Patent number: 7781078
    Abstract: A method and system for magnetic recording using self-organized magnetic nanoparticles is disclosed. The method may include depositing surfactant coated nanoparticles on a substrate, wherein the surfactant coated nanoparticles represent first bits of recorded information. The surfactant coating is then removed from selected of the surfactant coated nanoparticles. The selected nanoparticles with their surfactant coating removed may then be designated to represent second bits of recorded information. The surfactant coated nanoparticles have a first saturation magnetic moment and the selected nanoparticles with the surfactant coating removed have a second saturation magnetic moment. Therefore, by selectively removing the surfactant coating from certain nanoparticles, a write operation for recording the first and second bits of information may be performed.
