Method and apparatus for face recognition

Methods and apparatus are disclosed which are useful in rapidly verifying a person's identity at a distance, and/or identifying a person with a high degree of certitude, from a pool of other persons, using an innovative technique to compare facial images. Such a person (Candidate) may voluntarily consent or cooperate to have his facial image recorded, or the Candidate's facial image may have been recorded involuntarily. Typically, an image recorded for identification purposes will be a facial image of a Candidate present before a camera or other image procuring device, to be compared with a previously stored Reference facial image, as in a building lobby, for identification purposes. The Candidate's facial image is recorded voluntarily but the Reference image is not in the Candidate's possession. Reference images may be stored as Reference templates in an image storage database (such as developed by a governmental agency), or in an entrance lobby to the Candidate's apartment, or in a camera memory installed in a cockpit door of a transit vehicle to prevent access by hijackers. For verification purposes, the Reference facial image may be a hard copy, for example, a driver license, membership card, or passport in the Candidate's possession. A specially modified digital camera significantly reduces the requirement for a large memory to store templates, and makes it feasible to search for and identify rapidly (at distances up to 500 feet) suspects among a group of persons passing into or through such facilities as terminals, vehicles, customs stations, malls, ramps, etc. It is feasible to combine face recognition technology with other biometrics that express the degree of sameness as a numerical match score.

LTE channel measurement and feedback method

InactiveCN102546113ALower requirementReduce computational workloadError preventionTransmission path multiple useSignal-to-noise ratio (imaging)Transmission point
The invention discloses an LTE (Long Term Evolution) channel measurement and feedback method suitable for the CoMP (Coordinated Multi-Point) working mode. A base station configures CSI-RS resources for signal transmission points in the CoMP; a terminal performs channel measurement on the signal transmission points according to the CSI-RS resources, and feed the signal transmission points of which the signal-to-noise ratio satisfies the preset condition back to the base station; the base station selects the signal transmission points according to the feedback information of the terminal and the given working information of the base station side, and sets one or more measurement assumptions and corresponding CSI-RS resources; the terminal performs further channel measurement and feeds back the measurement information according to the measurement assumptions and the corresponding CSI-RS resources; and if the measurement information fed back by the terminal can not determine the resource dispatching mode, the terminal repeatedly performs measurement and feedback till the base station can determine the resource dispatching mode for resource dispatching. The method provided by the invention solves the problem in the prior art that the terminal has large calculated amount due to coexistence of various measurement assumptions.

Non-polar two-line system communication circuit

ActiveCN102324952ALower requirementFixed station two-conductor transmission systemsTemperature controlComputer module
The invention discloses a non-polar two-line system communication circuit which aims to solve the technical problem of preventing the occurrence of errors in the process of connection. The invention adopts the following technical scheme: a non-polar two-line system communication circuit comprises a host terminal and a slave terminal, wherein the host terminal is connected with the slave terminal and controls the slave terminal, the inside of the host terminal is provided with a host-terminal sending and receiving line module, the inside of the slave terminal is provided with a slave-terminal sending and receiving line module, and the host-terminal sending and receiving line module is connected with the slave-terminal sending and receiving line module in a non-polar two-line system connection mode. Compared with the prior art, an indoor unit controller for air conditioners supplies power for a temperature control device for air conditioners and carries out communication with the temperature control device by a power line, and the connection mode is a non-polar connection mode; and two lines can simultaneously carry out power supply and communication, thereby solving the problem that two lines simultaneously supply power and transmit signals, and reducing the demands on leads and installation.

Energy feeding type electrical energy mass perturbance generating device

The present invention discloses an energy-feedback type power quality disturbance generating device, which relates to a power quality disturbance generating device. The device comprises a harmonic source (1), a feedback link (2), a middle direct current capacitor (3), a control terminal (4), a first LCL filtering link (5), and a second LCL filtering link (6). The control terminal (4) adopts a DSP controller to realize that a control signal which is generated according to the setting of a user controls the harmonic source to partially generate current disturbance. The harmonic source and the feedback link are cascaded via the middle direct current capacitor to form an AC-DC-AC topological structure so as to realize power feedback. The alternating current side of the harmonic source is connected with a power network via the first LCL filtering link. The alternating current side of the feedback link is connected with the power network via the second LCL filtering link. The device is capable of simulating harmonic current, active current, inductance reactive current or capacitive reactive current of a plurality of combination frequencies, and the device is capable of simulating various working conditions of a plurality of nonlinear loads such as electric arc furnaces, medium frequency furnaces, welding machines and frequency converters, etc.
