摘要： Without using an interferometer, small displacement and/or three-dimensional shape of an object is detected in a noncontact way with high accuracy using pseudo-phase information calculated from e.g., a speckle pattern having a spatially random structure. A speckle image of the test object of the before displacement is obtained, and a spatial frequency spectrum is calculated by executing an N-dimensional Fourier transform for this. The complex analytic signal is obtained by setting the amplitude of frequency spectrum in the half plane including zero frequency in this amplitude distribution to zero, and executing the frequency spectrum amplitude in the half plane of the remainder in the inverse Fourier transform. And then, the amplitude value of this complex analytic signal is replaced with the constant value, a part of the obtained analytic signal domain is clipped, the phase information is calculated by the phase-only correlation function, and the cross-correlation peak in N-dimension is obtained. The displacement magnitude can be obtained by executing the above-mentioned method to the after displacement of the test object, and obtaining the difference of the cross-correlation peak before and after the displacement.

摘要： A waste disposer comprising a primary dehydrating chamber, a grinding device, a secondary dehydrating chamber, and a storage chamber. The primary dehydrating chamber is adapted to allow waste to be heated therein to partly dehydrate the waste. The primary dehydrating chamber has: a first waste inlet for receiving the waste, a first vapor outlet for exhausting vapor from the waste, a drainage outlet for draining free liquid from the waste, and a first waste outlet for outputting the partly dehydrated waste. The grinding device is adapted to receive the waste from the first waste outlet and grind the waste to reduce the size thereof. The secondary dehydrating chamber is adapted to allow the ground waste to be heated therein to further dehydrate the waste. The secondary dehydrating chamber has a second waste inlet for receiving the ground waste, a second vapor outlet for exhausting vapor from the waste, and a second waste outlet for outputting the further dehydrated waste. The storage chamber is adapted to receive the waste from the second waste outlet and store the waste in the storage chamber.

摘要： The present invention relates to a method and apparatus for detecting a signal propagation type. The method comprises: calculating a similarity value of a currently received pulse response and a reference pulse response when a certain positioning base station of a UWB positioning system currently receives a pulse response from a certain positioning tag, the similarity value indicating the degree of similarity between the currently received pulse response and the reference pulse response, wherein the reference pulse response is a pulse response previously received by the positioning base station from the positioning tag; and determining the current type of signal propagation between the positioning base station and the positioning tag on the basis of the similarity value. The method and apparatus can detect the type of signal propagation between the positioning base station and positioning tag of the UWB positioning system.

摘要： A person counting method and a person counting system are provided. The method includes extracting a group of person images to obtain a first image set; dividing the first image set into first and second subsets based on whether a related image exists in a second image set, and reusing a person ID of the related image; estimating posture patterns of images in the first subset, and storing the images in the first subset into an image library based on person IDs and the posture patterns; and selecting a target image whose similarity to an image in the second subset is highest from the image library, reusing a person ID of the target image when the similarity is greater than a threshold, and assigning a new person ID and incrementing a person counter by 1 when the similarity is not greater than the threshold.

摘要： This disclosure describes compositions and methods that involve a first modular component and a second modular component. The first modular component includes a first target molecule coupled to a first dimerizing moiety. The second modular component includes a second target molecule coupled to a second dimerizing moiety. The first dimerizing moiety dimerizes with the second dimerizing moiety when the first dimerizing moiety binds a chemical induced proximity (CIP) inducer.
