A method includes accessing a material database associating each of a plurality of materials with one or more corresponding resonance frequencies; for each material of at least a subset of the plurality of materials in the material database: transmitting, via an RF transmitter, an RF signal into a target at a first resonance frequency for each material; receiving, via an RF receiver, a response signal from the target; and analyzing the response signal for resonance characteristics that indicate a presence of each material in the target; generating a report of each material in the target indicated by the resonance characteristics; and integrating the report with at least one of: a timestamp; image or video data from a camera; or geolocation data from a geolocation sensor.

A spur measurement system uses a first device with a spur cancellation circuit that cancel spurs responsive to a frequency control word identifying a spurious tone of interest. A device under test generates a clock signal and supplies the clock signal to the first device through an optional divider. The spur cancellation circuit in the first device generates sine and cosine weights at the spurious tone of interest as part of the spur cancellation process. A first magnitude of the spurious tone in a phase-locked loop in the first device is determined according to the sine and cosine weights and a second magnitude of the spurious tone in the clock signal is determined by the first magnitude divided by gains associated with the first device.

A mobile terminal is provided that includes a metal frame including a base unit and a side unit, a main substrate located on a rear surface of the base unit, a display unit seated on a front surface of the base unit, and feed lines (231', 232') extending from the main substrate, connected to the side unit and supplying power to the side unit. The side unit includes a first conductive member including a first part and a second part, a second conductive member including a third part and a fourth part, a third conductive member located between the first and second conductive members, a first slit provided between the first and third conductive members and a second slit provided between the second and third conductive, and a length of the second part is two or more times a length of the first part.

A filtering device including a transmission line between an input and an output and a resonator, wherein a first microstrip track, a first micro-electromechanical system (MEMS) component, and a second microstrip track are connected in series between the transmission line and a ground point, and a second MEMS component is connected in parallel with the second microstrip track, the first and second MEMS components being switchable and being controlled by a circuit controlling the open or closed state of each of the first and second MEMS components, allowing the filtering device to be placed either in an all-pass operating mode or in a band-stop operating mode about a characteristic frequency of the resonator.

A method and device for moving an indicator on an on-screen keyboard depicted on a display device is described. A series of signals transmitted from a remotecontrol unit are received at the display device. The indicator on a grid depicted on the display device is moved based on the received signals. A reaction time for moving the indicator on the grid varies based on the series of signals received from the remotecontrol unit.
