    Abstract: A communication terminal device is a mobile communication terminal device that carries out communication for voice calls. The communication terminal device measures an orientation and a displacement of the device itself, and determines whether or not a condition occurring when a user picks up the device in his/her hand is met. In the case where it is determined that the condition occurring when the user picks up the device in his/her hand is met, and in the case where it has been determined that the user's head area has been detected as being near, the communication terminal device specifies a voice call partner on the basis of the orientation measured before the head area was detected as being near or while the head area was detected as being near. Then, when a tap operation performed by the user is detected, the communication terminal device performs a notification processing for making a notification of the specified voice call partner, and then makes an outgoing call to the partner.

  • Patent number: 10148304
    Abstract: A computing device with a Broadband Intelligent Antenna System (BIAS) that supports a broadband antenna design within the device. Each broadband antenna operates over a plurality of Radio Frequency (RF) bands to cover multiple different wireless technologies with a single antenna. The BIAS may continually monitor multiple triggers capable of affecting the signal quality of the wideband antennas and may automatically switch the active antennas accordingly to select an operating configuration that provides a higher signal quality of the active antennas. Triggers may be generated when, for example, one or more antennas are being blocked by a user, there is a change in the orientation of the device, a source of electrical noise is detected, unacceptable Specific Absorption Rate (SAR) proximity is detected, and so on. The trigger-based adaptive switching from one active antenna to the other may substantially improve the overall signal quality for the multiple wireless technologies supported by the device.

  • Patent number: 10135551
    Abstract: The method of identifying faulty antenna elements in massive uniform linear antenna arrays is a compressive sensing-based method that takes advantage of the reduction of the measurement matrix for a uniform linear antenna array to a partial discrete Fourier transform (DTF) matrix, whose rows correspond to the measurements' locations. Particularly, the method of identifying faulty antenna elements in massive uniform linear antenna arrays allows the measurements to be taken to reduce the measurement matrix's worst-case coherence, a factor which affects the detection probability of the defective antenna elements. The method constructs a measurement matrix with fewer distinct inner product values to reduce the worst-case coherence. In an alternative embodiment, the method focuses on bounding the inner product between any pair of measurement matrix columns.

  • Patent number: 10108903
    Abstract: In a general aspect, motion in a space can be detected based on machine learning of wireless signal properties. In some aspects, sets of tagged neural network input data are obtained at a neural network training system. Each set of tagged neural network input data is based on a statistical analysis of a series of wireless signals transmitted through a space over a respective time period, and each set of the tagged neural network input data includes a tag indicating whether motion occurred in the space over the respective time period. The sets of tagged neural network input data are processed by the neural network training system to parameterize nodes of a neural network system. Parameterizing the nodes configures the neural network system to detect motion based on untagged neural network input data.

According to some embodiments, estimated uplink and downlink actual temporal load available to a wireless device in a wireless network may be determined. An uplink data rate and a downlink data rate of the wireless device in the wireless network may be estimated. Based on the estimated uplink and downlink actual temporal load available to the wireless device and the estimated uplink and downlink data rates of the wireless device, the maximum possible uplink throughput and downlink throughput of the wireless device in the wireless network may be estimated. Such throughput estimates may be used to select a wireless network to join from among multiple available wireless networks or to select an initial data rate for an application executing on the wireless device, among possible uses.
