Abstract: An analog beamformer used for array antenna and an operating method thereof are provided. The analog beamformer used for array antenna includes an intermediate-frequency amplifying circuit, multiple local oscillators, multiple mixers, multiple radio-frequency amplifying circuits, and a frequency locking circuit. The analog beamformer uses a master-oscillator and multiple slave-oscillators which embed a resonant network of frequency-and-phase-locking. The intermediate-frequency amplifying circuit receives a baseband signal to provide an intermediate-frequency signal. Power supplies or grounding ports of different local oscillators are connected together to provide multiple local-oscillating signals with consistent frequency but different phases. The mixers individually receive the intermediate-frequency signal and one of the local-oscillating signals to provide multiple mixed signals.

Abstract: A driving event recording method and system for non-image-based car accident cause determination are disclosed. The system includes an external-event determination unit, an internal-driving-behavior-event determination unit, and a processor electrically connected to both determination units. The method is carried out as follows. The external-event determination unit generates information about an external event, and at the same time the internal-driving-behavior-event determination unit generates information about an internal driving behavior event. The processor receives the external-event information and the internal-driving-behavior-event information and uploads both pieces of information to a cloud storage space in a text or program code format for storage in a blockchain.

Abstract: A mobile electronic device stores a standard voice command and a voice command identification standard. When an incoming call is regarded as a missed call and a voice command is detected, the mobile electronic device compares characteristics of the voice command with characteristics of the standard voice command, so as to determine if the voice command satisfies the voice command identification standard. The mobile electronic device further activates a ringing circuit to play a predetermined ring tone in response that the voice command satisfies the voice command identification standard, so as to help a user locate the mobile electronic device even if the mobile electronic device is in a silent mode.

Abstract: A high viscosity liquid is fed into a rotation pack bed at a position with a distance far enough from a rotation axis, creating a centrifugal force exerted on the high viscosity liquid overwhelming a drag thereof, so that it can flow radially through the rotation pack bed. A high pressure gas is introduced into the rotation pack bed peripherally and/or a suction force source is connected to a position near the rotation axis, so that a volatile component contained in the high viscosity fluid is entrained in the gas counter currently flowing through the rotation pack bed and withdrawn from the position near the rotation axis, or the volatile component exits from the position near the rotation axis in gas phase, and thus the volatile component is removed from the high viscosity liquid. A second fluid can also be fed into the rotation pack bed to react with the high viscosity liquid, so that a reaction product is formed, and a volatile side product is removed at the same time.

Abstract: A method is used to remove an unreacted alcohol from an ester product mixture by a gas stripping. The method involves the feeding of the ester product mixture into proximity of an axis of a rotating packed bed, so as to enable the ester product mixture to flow radially to come in contact with a gas which is introduced into the rotating packed bed. The unreacted alcohol and any other volatile component of low molecular weight are thus stripped from the ester product mixture by the gas entrainment, thereby resulting in production of a purified ester product which is collected at the bottom of the rotating packed bed. The unreacted alcohol and the volatile component, which are entrained in the gas, are discharged via an exit located at the top of the rotating packed bed.
