Abstract: The present application discloses a method and apparatus for detecting a vehicle contour based on point cloud data. The method includes: acquiring to-be-trained point cloud data; generating label data corresponding to points in the to-be-trained point cloud data in response to labeling on the points in the to-be-trained point cloud, the labeling used to indicate whether each of the points in the to-be-trained point cloud data is on a vehicle contour; training a fully convolutional neural network model based on the points in the to-be-trained point cloud data and the label data corresponding to the points in the to-be-trained point cloud data, to obtain a vehicle detection model; and acquiring to-be-detected point cloud data, and obtaining a detection result corresponding to each to-be-detected point in the to-be-detected point cloud data based on the vehicle detection model. The implementation may achieve an accurate detection of the vehicle contour.

Abstract: The core of a high temperature furnace has an elongated central test cavity for testing/calibration of a temperature-sensitive component, such as the probe of a thermocouple. At least three electrical heating elements as positioned adjacent to the test cavity, including two elements adjacent to the opposite end portions of the test cavity, respectively, and a center element between the end elements. A uniform temperature profile is maintained in the cavity by control circuitry that manages the supply of electrical power to the heating elements, by periodically configuring interconnections of the elements during multiple phases of a duty cycle. The duty cycle includes a first phase in which current is passed through the center element, a second phase in which current is passed through the end elements in series, and a third phase in which current is passed through one of the end elements and also through the center element without passing current through the other end element.

Abstract: The invention is to a flat folding chair, including a seating frame and cushion fixed on a seating frame, and on front and rear supporting bars which support the two sides of the seating frame. A slide sleeve is installed on the rear supporting bar with the front supporting bar sliding through the slide sleeve to form the movable joint between the supporting bars. A stopper is installed on the front supporting bar. The slide sleeve rests upon the stopper when the folding chair is unfolded to the correct position. There is also a fixation lock installed between the stopper and the slide sleeve to automatically lock the chair when unfolded to the correct position. A clicking sound of the handle snapping into the lock hole serves as a signal to the user that the chair has been opened to the correct position.

Abstract: A method for delivering medicament such as for ameliorating pain in a patient includes introducing an injector through a nasal passage of the patient into a region substantially medial and/or posterior and/or inferior to a sphenopalatine ganglion (SPG) of the patient; and delivering a medicament from the injector superiorly and/or laterally and/or anteriorly towards the SPG. A device for delivering a medicament to a patient in need thereof includes (a) an injector containing a first end configured to remain outside a nasal passage of the patient and a second end configured for entry into the nasal passage of the patient; and (b) an introducer configured for engagement with a nostril of the patient and containing a passageway configured for slidably receiving the injector. The injector is moveable between a storage position preceding the engagement and an engaging position pursuant to the engagement.

Abstract: The present invention relates to a folding table. The folding table includes a first table top and a second table top that can move between a folding position and an unfolding position, as well as a first and second table leg component for supporting the second table top, wherein two sets of mutually hinged four-link mechanisms are formed by the first and second table leg component in virtue of table beams, table legs and inclined rods. The two sets of four-link mechanisms realize interference self-locking in the unfolding process. Two triangles are formed for supporting a table top stably, and the stress is uniform. The table top can be folded face to face in two parts, so that the table top after being folded is effectively protected, and scratches on the table top during the production, transportation and using processes are reduced.

Abstract: A cryogenic cooling manifold and methods incorporating a cryogenic cooling manifold for managing the gas layer(s) above a liquid cryogen to control cooling temperature-time profiles and ice formation for microliter and smaller samples that are plunged through the gas and into the liquid cryogen.

Abstract: A foldable frame that can unfold into a complete open structure, and is convenient for converting into a storage container with an upward facing opening. The upper frame body and lower frame body are connected with the central pillars and support rods on both sides, and form a 6-pillar support structure at both ends of the frame, so that the frame can support more weight, realize multi-layer stacking or support other articles, such as desktop or seat surface.

Abstract: The invention relates to a foldable shelf consisting of vertical frames at both ends, two layers at least, link rods and two cross rods connecting the upper and lower layer. Each layer includes two symmetric pieces hinged into a foldable structure between the two frames, and the two layer ends are separately hinged to the frame. One end of the cross rod is hinged to a sleeve which is movably attached to the link rod; the shelf is characterized in that: the cross rod is an “L” shaped structure with a transverse rod and a vertical rod, in which the former crosses and is hinged to both sides of the frame, and the end of the latter is hinged to the sleeve. By the “L” shaped cross rod, both frames form a rigid, triangular and a stable structure with a vertical plane of the shelf, and the entire structure is more cost effective and practical.

Abstract: The present invention teaches an integrated folding table and chairs set, comprising a table and two chairs. The table comprises cross hinged table legs on both sides and a table top. The chair comprises the same or symmetrical supporting legs on both sides, a cushion and a back cushion. The supporting leg comprises mutually crossing front supporting rods and rear supporting rods. The front supporting rod extends upward from the cushion to form back cushion segments. A back cushion is installed on either back cushion segment, and the cushion is fixed to the front supporting rod and rear supporting rod; wherein, the table legs respectively comprise two cross hinged U-shaped rods. The top cross rod of the two U-shaped rods is used to fix and support the table top.

Abstract: A testing system and method incorporate a test signal generator for generating a test signal with multiple tones uniformly distributed across a wideband having a specific bandwidth. This test signal is generated based on user-specified test signal parameter(s) (e.g., using an orthogonal frequency-division multiplexing (OFDM) spread spectrum technique) and processed (e.g., converted from digital to analog or shifted to a different wideband having the same bandwidth), as necessary, so that it is suitable for application to a specific device under test and so that the tones account for the full range of frequencies with the wideband operation of that device under test. After it is applied to the device under test, the resulting output signal is captured, processed (e.g., converted back to digital or shifted back to the initial wideband), as necessary, and analyzed in order to determine the frequency responses associated with each of the tones.
