Patent GB-2605408-A (GB)
Title: Laser welding position determination
Inventor: MO AL-BADANI
IPC: H01R4/62
Filed: 2021-03-31
Abstract: Laser welding can be used to join a plurality of connection tabs to cell terminals in a busbar arrangement. The process involves a positioning step which sets in space, with respect to a first axis, respective positions of each connection tab and cell terminal. A measuring step obtains measurements indicative of the first axis position of each of the connection tabs. The welding step comprises determining a respective focus distance to be used for the welding laser beam, and welding, in turn, each connection tab to its respective cell terminal. The incidence direction of the welding laser beam on each connection tab and cell terminal has a component direction in the first axis direction. A laser rangefinder cart 122 running on a rail 126, and a laser welding cart 146 on a track 144 may be used. Cells may be cylindrical with positive and negative terminals at one end (fig 1).

Abstract: A telehealth training system is provided which employs a three-dimensional camera programmed for capturing image data associated with an exercise program performed by a user. A computer-implemented body pose analysis and scoring module analyzes and scores body poses of the user while the user performs the exercise program. The analysis and scoring module may calculate scores in response to reference data related to at least one exercise prescribed for the user, and then compare processing results to the reference data. A feedback module may be included in the system which is programmed for creating and animating an avatar in response to the processing results of the analysis and scoring module. In certain aspects, the analysis and scoring module may be programmed for using a voxel basis function (VBF) technique in connection with performing pose matching analysis in association with the user performing the exercise program.

Abstract: In the heat treatment of steel wires (W) in a patenting operation, the wires from an austenitizing furnace (1) are first quenched in a fluidized bed (Q). This bed (Q) is fluidized by hot gases from the furnace (1) and is also provided with a cooling system (28). The wires are then passed into a second fluidized bed (TR-S) where transformation takes place. This bed is fluidized by an independent source of hot gas (21) and is divided into regions (13) along its length which have independently controllable auxiliary heaters (14). The temperatures in the zone (Q) and the region (13) along zone (TR-S) are controlled to give a fine pearlite microstructure in the wire.

Abstract: A first plastic strip (21) has longitudinally spaced studs (22) each of which can be bent over at a 90 DEG  angle. A second strip (26) has holes (27) through which the studs fit and grooves (29) which receive and secure the bent over studs. Paper punched to receive the studs is clamped between the two strips. The studs are then bent over into grooves in the second strip and held in bent position. The grooves have overhanging lips (31) which detachably retain the studs in place. The paper is thus securely bound. To prevent cracking the studs, the abruptness of the 90 DEG  bend may be relieved by forming an annular depression (36) around the base of each stud.
Patent KR-870001516-A (KR)
IPC: G06F7/48
Filed: 1986-07-14
Abstract: Circuitry for forming the twos complement or ones complement of N-bit binary numbers is described. The circuitry includes N stages each of which contains an exclusive NOR gate (300, 310, 320, 330, 340, 350). A first input terminal (B) of the exclusive NOR gate is coupled to receive one bit of the input value and a second input terminal (C) is coupled to receive the carry output signal from the previous stage. A logic one or logic zero is applied to the second input terminal (C) of the exclusive NOR gate (300) of the stage which processes the least significant bit of the binary word if the circuitry is to provide a twos complement or ones complement value respectively. The carry output signal for each stage is generated by ANDing (302, 312, 322, 334, 342) a logically inverted version of the input bit signal with the carry input signal applied to the stage. An application of the complementing circuitry in an absolute value circuit is also described. In this application, the carry input signal to each stage is ORed (612, 622, 632, 642, 652) with a logically inverted version of the sign bit of the input value and the result is applied to the second input terminal (C) of the exclusive NOR gate. This circuitry complements only negative values, passing positive values unchanged.
