  • Patent number: 10006884
    Abstract: Determining a Curie temperature (Tc) distribution of a sample comprising magnetic material involves subjecting the sample to an electromagnetic field, heating the sample over a range of temperatures, generating a signal representative of a parameter of the sample that changes as a function of changing sample temperature while the sample is subjected to the electromagnetic field, and determining the Tc distribution of the sample using the generated signal and a multiplicity of predetermined parameters of the sample.

  • Patent number: 9685183
    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.

  • Patent number: 9489051
    Abstract: A device and method to facilitate display navigation by touch-less gesture are described. The device includes two or more ambient light sensors arranged at respective surface locations of the device, each of the two or more ambient light sensors measuring light intensity at the respective surface location. The device also includes a processor to detect a gesture as a detected gesture performed by an object in touch-less communication with the device and output a signal corresponding with the detected gesture, and a navigation gesture library to store two or more gestures and corresponding two or more signals, wherein the processor accesses the navigation gesture library when the device is not executing an application with an associated application gesture library.

  • Patent number: 9337909
    Abstract: A communication device of a mobile terminal and a mobile terminal are provided. The communication device includes a communication module mainboard that has a communication module disposed thereon; a main antenna that is coupled to the communication module mainboard; a MIMO antenna capable of enhancing signals; and a MIMO board coupled to the communication module mainboard via a spring contact plate; and the MIMO antenna is coupled to the MIMO board via a coaxial cable. Since the main antenna and the MIMO antenna are separately disposed, their interference can be reduced, and the overlapping disposal of the main antenna and the MIMO antenna can be avoided, and the thickness of the mobile terminal can be reduced. The MIMO antenna is coupled to the communication module via the coaxial cable, so the MIMO antenna can be freely adjusted and disposed anywhere within the mobile terminal.

  • Patent number: 9277349
    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. The message class and the determined state of motion is used to select an action to relay the communication to a driver of the vehicle.
