Abstract: An ignition method of a plasma chamber includes steps of: (a) starting softly an ignition voltage to a first voltage, (b) decreasing the magnitude of the ignition voltage to a second voltage after a first ignition time, (c) increasing the magnitude of the ignition voltage to the first voltage after a second ignition time, and (d) repeating the step (b) and the step (c) until the ignition is successful.

Abstract: System that facilitates rapid onboarding of an autonomous (cashier-less) store by capturing images of the store's items from multiple angles, with varying backgrounds, and that builds a classifier training dataset from these images. The system may have cameras in different positions, and backgrounds that generate different background colors. It may have a platform for items that can be switched between a transparent and non-transparent state; cameras below the platform may therefore capture images of the bottom side of the item when the platform is transparent. When an item is placed in the imaging system, a fully automated process may generate a sequence of background colors and may capture and process images from all of the cameras to create training images. Images of the item from multiple angles, including views of the entire external surface of the item, may be captured without requiring an operator to move or reorient the item.

Abstract: System that facilitates rapid onboarding of an autonomous (cashier-less) store by capturing images of items in the store's catalog from different angles, with varying backgrounds and lighting conditions, and that automatically builds a classifier training dataset from these images. The system may have cameras in different positions, lights supporting variable illumination, and monitor screens that generate different background colors. It may have an input device such as a barcode reader, and an operator terminal that prompts operators to place items into the imaging system in the necessary orientations. Once an item is placed in the imaging system, a fully automated process may generate a sequence of background colors, a sequence of lighting conditions, and may capture and process images from all of the cameras to create training images. Training images for an item may be generated in seconds, compared to many minutes per item using manual image capture and processing.

Abstract: A system that integrates camera images and quantity sensors to determine items taken from, placed on, or moved on a shelf or other area in an autonomous store. The items and actions performed may then be attributed to a shopper near the area. Shelves may be divided into storage zones, such as bins or lanes, and a quantity sensor may measure the item quantity in each zone. Quantity changes indicate that a shopper has taken or placed items in the zone. Distance sensors, such as LIDAR, may be used for shelves that push items towards the front. Strain gauges may be used for bins or hanging rods. Quantity changes may trigger analysis of camera images of the shelf to identify the items taken or replaced. Images from multiple cameras that view a shelf may be projected to a vertical plane at the front of the shelf to simplify analysis.

Abstract: A wire reel structure includes a casing body, a reel unit and a signal line unit. The casing body includes a central pillar, and the reel unit is contained in the casing body. The signal line unit includes first and second signal lines, and the first signal line is passed into reel unit and wound at an external side of the reel unit. The second signal line is connected to the first signal line and wound at an external side of the central pillar. The first and second signal lines are signal lines with different deformation curves, and the second signal line has a greater flexibility than the flexibility of the first signal line, such that the second signal line will not be folded reversely when wire sections in the casing body are rotated.

Abstract: A locking structure for fixing the disk piece, which comprises: a dish seat including a base portion and a plenty of flexible arms, and a pressing unit including a locking portion for locking the disk piece. Each flexible arm connects to the base portion, and protrudes outwardly from the base portion. The base portion has an adhesive face for sticking on any article or place. The pressing unit forms on the center of the dish seat, each flexible arm protrudes from the base portion and connects to the pressing unit. The locking structure of the present invention can be installed on any article or place, and fix the disk piece on the locking structure, so that the disk piece can be fixed on any place. Moreover, the locking structure of the present invention can be accessed easily and has a beautiful appearance.

Abstract: The present invention discloses a cable reel, which comprises a casing, a movable latch member pivotally coupled into the casing, a protrusion disposed at one end of the latch member, a turntable disposed under the latch member and pivotally coupled into the casing, a volute spring disposed on a turntable, a cable disposed in the in the turntable, and an adapter can be connected to one end or both ends of the cable. Further, the turntable has a groove, and an inclined guide groove and an arc indented groove are disposed proximate to the groove such that the protrusion on the latch member in conjunction with the inclined guide groove and the arc indented groove can fix the cable at the currently located position and will not retract the cable into the cable reel when the cable is pulled. On the other hand, the cable is pulled gently again if it is necessary to rewind the cable.

Abstract: The present invention discloses an intelligent power socket, which comprises a first socket being connected to a second socket by a compare amplify circuit, and the second socket having a control circuit. The compare amplify circuit compares the voltage outputted from the first socket with a standard voltage and outputs a signal to the control circuit, so that the control circuit will follow the instruction given by the signal to turn on or off the power of the second socket as the power of the first socket is turned on or off. The present invention not only reduces the power consumption, but also turns off the power of all sockets automatically, and thus making the operation simple and easy.
