A wire reel is detachably provided in a housing chamber of a binding machine body which binds a reinforcing bar. The wire reel includes a cylindrical hub portion which winds a wire, and a pair of parallel flanges overhanging outward from both external peripheral ends of the hub portions. A side wall inside the hub portion is formed of light-transmitting portions which allow the light from a transmissive photosensor provided in the binding machine body to be transmitted therethrough.

Provided is a refrigerator including: a storage chamber having an infrared sensor which detects a surface temperature of food; and an adjacent storage chamber starting from the infrared sensor as a start point and adjacent to a projection plane of the detection plane of the infrared sensor. The storage chamber and the adjacent storage chamber are maintained in the same temperature band so as to improve the accuracy of a temperature detected upon door open and close. Moreover, by suppressing condensation and temperature fluctuations of a thermistor itself which may cause an erroneous detection, it is possible to stably detect the food temperature.

The present invention aims at providing a method for detecting a color of a signal light from a moving vehicle such as railroad train. The method includes capturing an image from a camera mounted on the moving vehicle and extracting candidate regions in the image that contain light region. The method further includes classifying the candidate regions as a signal light region or a non-signal light region and identifying the color of the signal light region.

A numerical control apparatus having tool cutting edge detecting unit for detecting a cutting edge position of a tool mounted on a tool rest, comprises detection signal determining unit for determining, as effective, only a detection signal that is first inputted from among a plurality of detection signals which are continuously inputted from the tool cutting edge detecting unit. A signal which is detected until a preset time is elapsed after a first signal is received when the tool comes into contact with the touch sensor, and/or until the tool moves a predetermined distance, is determined as erroneous detection by the detection signal determining unit, and the signal is disenabled.

The invention discloses a voice activity detection method and device, and a readable storage medium. The voice activity detection method comprises the steps: obtaining a collected voice signal; respectively adopting a voice noise reduction algorithm and a harmonic detection algorithm to judge whether the voice signal has voice activity or not; and when both the voice noise reduction algorithm andthe harmonic detection algorithm judge that the voice signal has voice activity, judging that the voice activity is detected from the voice signal. By adopting the scheme, the voice activity can be accurately detected.

A system, method and footwear sensor unit a footwear sensor unit removably attachable to footwear, the footwear sensor unit including: an Inertial Measurement Unit (IMU) including a 3-axis accelerometer and a 3-axis gyroscope, the IMU adapted to gather sensor data of detected movements of the footwear; and a storage device in electronic communication with the IMU, the storage device for storing the sensor data; and a communications module in electronic communication with the storage device, the communication module configured to transmit data to an external computing device.

Systems and methods to identify an object using a radar system involve arranging an array of antenna elements into two or more subarrays with a tilt angle relative to each other. Each of the two or more subarrays includes two or more antenna elements among the array of antenna elements. A method includes receiving reflected signals at each of the two or more subarrays resulting respectively from transmitting transmit signals from the two or more subarrays, and processing the reflected signals at each of the two or more subarrays to obtain an amplitude associated with each azimuth angle in a range of azimuth angles. A location of the object is determined as the azimuth angle in the range of azimuth angles at which the amplitude exceeds a threshold value.

The invention provides a banknote identification device which is simple in structure and can eliminate error detection of banknote inserting which is caused by external light influence coming in froma banknote inserting port. The banknote identification device comprises a reflection sensor (S1), a high pass filter (30) and a banknote inserting part determination part (31). The reflection sensor (S1) is arranged in an inserting guiding member which is used for guiding the banknote which is inserted from the banknote inserting port (11) and is used for transmitting regulated AC signal light andreceiving reflection light. The high pass filter (30) allows a frequency band containing the frequency band of a regulated AC signal light in a receiving signal outputted by the reflection sensor (S1) to pass; the banknote inserting determination part (31) determines whether the banknote (100) is inserted into the banknote inserting guiding member (12) through a receiving signal of the high passfilter (30).

The invention discloses a detection method and system for a position of a fetal nape transparent object with combination of medical statistical information. The method comprises the realization process: establishing a standard image database, to obtain the average offset value of a head area and a fetal nape transparent object thickness (NT) area; inputting an ultrasound image to obtain conversionparameters of the pixel distance and the actual d distance of the ultrasound image; determining the head area; and through the determined head area, and the average offset value between the head areaand the NT area, determining the NT area, namely, the position of the fetal nape transparent object. The position of the head area is determined firstly, the NT area is determined by the average offset value of the head area and the NT area, and the overall accuracy and stability of the detection method are improved by combining the standard or prior knowledge of the NT ultrasound image.
