A portable urine detection device and method is disclosed by the invention which relates to the technical field of urine detection. The invention includes a detection device and a cloud backstage system, of which the detection device comprises a shell, a slot component, a fixed component and several test strips. The circuit board is fixed in the shell. Several LED lamp beads, a camera module, a first algorithm module, a second algorithm module, a third algorithm module and a fourth algorithm module are fixed on one surface of the circuit board. One side of the circuit board is provided a USB port; one side of the USB port penetrates one side of the shell; the other side of the shell is provided with an opening; one side of the shell is connected with a smart phone through a USB port and an OTG data line. The fixed component comprises a bottom plate. According to the invention, the problems of overlarge volume, incapability of universal use and higher cost of the existing urine detection device are solved by designing a novel urine detection structure which is designed by a corresponding algorithm module that connected with the cloud.

A multi junction solar cell is provided with a non-alloyed ohmic contact metallization stack by inversion of the top semiconductor layer from n-type to p-type and including the utilization of a tunnel junction. Alternatively, the non-alloyed ohmic contact can be achieved by changing the top semiconductor layer from a higher bandgap material to a lower bandgap material.

A computer-aided writing system offers assistance to a user writing in a non-native language, as the user needs help, without requiring the user to divert attention away from the entry task. The writing system provides a user interface (UI) that integrates writing assistance with in-line text entry. When the user is unsure of a word's spelling or whether the word is appropriate, the user may enter a corresponding native word directly in line with the ongoing sentence. An error tolerant spelling tool accepts the native word (even if it is misspelled or mistyped) and derives the most probable non-native word for the given context. The spelling tool consults a bilingual dictionary to determine possible non-native word translation candidates, a non-native language model (e.g., a trigram language model) to generate probabilities associated with the candidates given the current sentence or phrase context, and a translation model to generate probabilities of how likely a certain native word was intended given the non-native word candidates. From these probabilities, the spelling tool determines the most probable non-native word translation and substitutes the non-native word for the native input string. If the user likes the non-native word, the user may simply continue with the sentence. On the other hand, if the user is still unsure of the non-native word, the user can invoke a sentence recommendation tool that allows the user to see the non-native word in a bilingual sentence pair to learn how the word can be used.
摘要:
Techniques for media segmentation are disclosed. A number of measures used to generate similarity values are compared. Two different approaches to calculate feature vectors based on pairwise frame similarity in combination with different kernel functions are disclosed. A supervised classification method is used with the feature vectors to assess segment boundaries.

A method for vertically grounding and leading down form a center of a composite pole tower includes the following steps: extending a ground down-leading wire from a center of a ground wire cross arm which is made of metal and is positioned on top of the pole tower, wherein the ground down-leading wire is vertically leaded down to the earth form the center of the composite pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is extended from the center of the composite material and is directly connected to the metal pipe. The method utilizes the advantage of the insulating intensity of the wall of the composite pole tower and enhances the insulating intensity of the transmission line on impact of lightning. The ground down-leading wires are prevented from short-circuiting with the tower body of the composite pole tower, so that advantage of the insulating property of the composite material of the pole towers is realized. Since the ground down-leading wire is penetrated through center of the pole tower, so that the ground down-leading wires are not exposed and are prevented from destroying by external force. And also the method is easy and simple for application.

A method for vertically grounding and leading down form an inner side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm which is made of metal, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The upper metal cross arm and the lower cross arm are able to provide a distance between the ground down-leading wire and the pole tower. The method enhances the ability of bearing lightning flashover, increases the insulating intensity to lightning impact, and prevents burning to composite insulator by power-flow current after lightning flash over. And also the method is easy and simple for application.

A method for vertically grounding and leading down form an outer side of a composite pole tower and pole tower thereof, wherein the method includes the following steps: extending an upper metal cross arm from an extended line of at least one side of a ground wire cross arm, vertically leading down a ground down-leading wire from a distal end of the upper metal cross arm, connecting the ground down-leading wire to the pole tower via a lower metal cross arm at a distance under a lower lead, and grounding the ground down-leading wire along a tower body of the pole tower, wherein when an lower portion of the tower body is a metal pipe, the ground down-leading wire is selectively directly connected to the metal pipe via the lower metal cross arm. The method facilitates in compressing the width of the transmission corridor to a maximum extent as well as designing a lightning protection, preventing the ground down-leading wire from short-circuiting with the tower body, and realizing the insulation function of the composite material tower body. The manner of using unilateral ground down-leading wire saves material, and is economical and simple in structure.
