Patent EP-4287138-A1 (EP)
Inventor: SHANMUGA VADIVEL KARTHIKEYAN
IPC: G06V10/24
Filed: 2023-05-30
Abstract: This disclosure provides methods, devices, and systems for training machine learning models. The present implementations more specifically relate to techniques for automating the annotation of data for training machine learning models. In some aspects, a machine learning system may receive a reference image depicting an object of interest with one or more annotations and also may receive one or more input images depicting the object of interest at various distances, angles, or locations but without annotations. The machine learning system maps a set of points in the reference image to a respective set of points in each input image so that the annotations from the reference image are projected onto the object of interest in each input image. The machine learning system may further train a machine learning model to produce inferences about the object of interest based on the annotated input images.

Abstract: In a heat insulating compound frame (1) in which two profile rails (21, 22) are connected together by means of insulating webs (3), it is envisaged to arrange at intervals deformations on the support webs (4) of undercut grooves in which the insulating webs (3) engage, which deformations project into the inside of the groove and butt against the insulating web (3) or penetrate therein. This makes it possible for the profile rails (21, 22) to be held securely on the insulating webs (3) and increases the shear strength of the compound frame. The deformations (7) on the support webs (4) are made with tools which are passed through the cavity (8) of the compound frame. The deformation tools may be expansion wedges (98) equipped with swivel arms, spikes (80) being situated on the swivel arms (29) for producing the deformations; furthermore, the deformations may be pressed in using disc wheels, and finally the deformations can be produced using strips on which individual projections or teeth are attached, in such a way that these strips are introduced into the cavity of the compound frame and are pressed against the support webs with a draw key. <IMAGE>

Abstract: Les performances d'une electrode a lit fluidise sont augmentees en donnant aux particules (3) suspendues des vitesses plus grandes tout en maintenant un degre relativement faible d'expansion ou evacuation du lit. Ceci est mis en oeuvre dans une realisation de l'invention (Fig. 2) au moyen de paires de jets d'electrolyte opposes se heurtant l'un contre l'autre en vue d'obtenir un deplacement tres turbulent des particules fluidisees tandis que la vitesse du debit de l'electrolyte de support est maintenue relativement basse. Dans un second mode prefere de realisation (Figs. 3 et 4), la vitesse du debit de l'electrolyte peut etre aussi elevee qu'on le desire, mais son sens, de preference horizontal, est inverse a intervales frequents. Ainsi, par intermittence, les particules suspendues se tassent contre les filtres (10, 11) qui les retiennent, aux parois de sortie alternatives (6, 7). Le tassement et l'expansion par alternance donnent un transfert de charge et de masse ameliore, et par consequent une meilleure performance de l'electrode. La presente amelioration s'applique en particulier aux lits fluidises de particules de charbon actif et d'autres materiaux dont la densite n'est pas beaucoup plus grande que celle de l'electrolyte de support.

Abstract: A torque multiplier assembly (A) that is portable, compact, and may be easily and conveniently disposed adjacent a nut, bolt or similar threaded elements to removably engage the same. The torque multiplier assembly (A) when so engaged is adapted to exert a first relatively high maximum torque of predetermined value on the nut, bolts or similar elements to initially rotate the same from binding threaded engagement or perform the final tightening of the nut, bolt or rotatable element. The torque multiplier assembly (A) is manually actuated by the use of an elongate torque wrench (B) of a type that is commercially available and may be adjusted to supply any one of a number of maximum torque. The desired maximum torque supplied by the elongate torque wrench (B) is relatively low, normally not over fifty foot pounds, and is visually indicated on a calibrated scale (14,15) that forms a part of the torque wrench (B). The maximum torque supplied by the torque wrench (B) is transferred to the multiplier assembly (A) with the torque output of the multiplier assembly (A) being the torque input of the torque wrench multiplied by a factor that is inherent to the specific gear structure of the multiplier assembly (A).
