摘要： A silicon microelectromechanical system, MEMS, resonator assembly, includes four flexural beam elements forming a rectangular frame, each beam element being connected at an end thereof to an end of a neighboring one of the beam elements. The resonator assembly further includes connection elements for connecting the rectangular frame to at least one mechanical anchor, and the resonator assembly supporting an in-plane flexural collective resonance mode.

摘要： Surface acoustic wave (SAW) structures with transverse mode suppression are disclosed. In one aspect, the SAW structure provides digits or fingers with broad interior terminal end shapes. By providing such shapes spurious modes above the resonance frequency of the SAW are suppressed thereby providing desired out of band rejection that helps satisfy design criteria such as keeping a higher Q value, a higher K2 value and better Temperature Coefficient of Frequency (TCF).

摘要： There is provided a data processing apparatus and method. The data processing apparatus comprises a filter circuit comprising storage circuitry to store program counter values and to assert a trigger signal in response to a lookup operation using a current program counter value hitting in the storage circuitry. The processing apparatus comprises a processing unit to generate an output in response to the trigger signal. The processing apparatus is provided with resolution circuitry, associated with a downstream processing stage, to determine whether the output is of use, and in that event to assert a false miss indication in the absence of the processing unit having been triggered to produce the output. The filter circuit is configured to maintain a trigger sensitivity metric in dependence on the false miss indication, and the chosen number of bits employed when performing the lookup operation is dependent on the trigger sensitivity metric.

摘要： Drones are engineered with sensors for use in insurance applications. After locating an object of interest, a drone performs an investigation by probing the object of interest. Sensors receive feedback from the object of interest. An electronic fingerprint of the drone is produced. Afterward, perils are computed based on the feedback and the fingerprint of the drone is used in insuring the object of interest. The act of probing includes thumping, drumming, or radiating ultrasound waves against the object of interest. The sensors can be turned off when they are within a geographic zone of prohibited operations.
