Title: Authentication management computer, authentication system, and authentication method using transaction details
Inventor: Seong Min YOON
IPC: G06Q20/40
Filed: 2021-06-18
Abstract: The present invention relates to an authentication management computer, an authentication system, and an authentication method using transaction details. The present invention proposes an authentication management computer for performing user authentication using a user's transaction details, and an authentication system and authentication method using same. The authentication management computer: controls execution of a stored program by using hardware resources; receives a user's authentication request data; receives the user's identity verification information provided by a transaction counterpart of the user; analyzes information on a transaction pattern between the user and the transaction counterpart; and performs user authentication on the basis of the consistency between the analyzed user's transaction pattern information and transaction pattern information stored in the authentication management computer.
Patent GB-2619377-A (GB)
Title: Vehicle operation using a dynamic occupancy grid
Inventor: DMYTRO S YERSHOV
IPC: G01S17/89
Filed: 2021-05-12
Abstract: Methods for operating a vehicle in an environment include receiving LiDAR data from a LiDAR 123 of the vehicle, representing objects 191, 192, 193 in the environment. A dynamic occupancy grid (DOG) (Fig. 13: 1300) is generated based on a semantic map. The DOG includes multiple grid cells (Fig. 13: 1305, 1310) each cell representing a portion of the environment. For each grid cell, a probability density function is generated based on the LiDAR data, which represents a probability that the represented portion of the environment is occupied by an object. The dynamic state of cells can be addressed by modelling objects or free space as a collection of particles (Fig. 13: 1315) where particles represent a set of interacting variables forming a virtual representation of objects, similar to field theory-based modelling in fluid dynamics. The particle density function can be defined in a time-space-velocity coordinate frame. The occupancy state of a grid cells can be computed using a Bayesian filter. A time-to-collision (TTC) of the vehicle and the object less than a threshold time is determined based on the probability density function. If the TTC is less than the threshold time, a control circuit of the vehicle operates the vehicle to avoid a collision of the vehicle and the object.
Patent GB-2617902-A (GB)
Title: Self-aligning bearing support assembly
Inventor: Fernando Porchas Iniguez
IPC: B25F5/00
Filed: 2023-02-23
Abstract: Power tool (1; fig. 1) comprises a housing 2, electric motor 22, motor output shaft 23, bearing 26 supporting an end of the shaft, and a support assembly 40 including a cap 41 having a sidewall 43 surrounding a cap centreline (46; fig. 11). Cap recess (49; fig. 12) receives the bearing. Outer surface (48; fig. 12) of cap sidewall may include convex (50, 53; fig. 12) and planar (56, 57; fig. 12) portions extending between shoulders (51, 52, 54, 55; fig. 12) corresponding to concave portions (12(1b), 12(2b); fig. 7) on an inner surface of the housing to support the cap in the housing. The cap is moveable along two orthogonal axes (X, Z; fig. 4), and rotatable about three orthogonal axes (X, Y, Z; fig. 8) providing bearing self-alignment and adjustment. Assembly 40 may include resilient boot 80 between the bearing and cap to dampen motor vibrations.

Title: Deriving profile data for compiler optimization
Inventor: VIJAY SUNDARESAN
IPC: G06F11/36
Filed: 2021-08-27
Abstract: An method includes requesting, by a compiler responsive to execution of a first code segment, a first profile dataset associated the first code segment. The method also includes executing, responsive to receiving an indication that the first profile dataset is not available, a querying process that searches other code segments based on specified criteria relating to an attribute of the first code segment. The method also includes receiving a search result from the querying process, where the search result includes a second code segment. The embodiment also includes generating an extrapolated profile dataset based at least in part on the second code segment. The method stores the extrapolated profile dataset in memory associated the first code segment, and the compiler performs an optimization process on the first code segment using the extrapolated profile dataset.

Title: Double action toothbrush
Inventor: SAPOUNIDIS CHRYSOSTOMOS
IPC: A46B9/04
Filed: 1988-12-02
Abstract: This toothbrush is comprised of two heads (2) and its handle (1). The two heads are symmetrically placed with their bristles converging, facing each other. The toothbrush can be of different sizes (small, large, medium) and varying bristle quality (hard, soft, natural bristle, etc.). With this toothbrush, cleaning of teeth as well as gum massage is simultaneously facilitated over both external and internal tooth areas. Therefore, better results are achieved in far less time.

Title: Endoscopic ligation and division instrument
Inventor: DAVISON MARK A
IPC: A61B17/12
Filed: 1993-05-03
Abstract: An endoscopic surgical apparatus capable of ligation and division. The apparatus has a frame (25) and a tubular shaft (20) attached to said frame. Also attached to the frame is a handle (65). The apparatus has ligating means (190) and cutting means (600). Actuation means are mounted to the apparatus for actuating both the ligating means and the cutting means. The apparatus has a clutch means (130) capable of enabling the actuating means to switch between a first mode for actuating the ligating means and a second mode for actuating the cutting means. The cutting means is preferably an extendable J-hook and blade assembly. The cutting means and ligating means are preferably rotatable with respect to the frame. The ligation and division apparatus may be used to ligate and cut blood vessels or tissue in a mammalian body cavity during a surgical procedure. <IMAGE>

Abstract: An electrodynamic loudspeaker (1) has a diaphragm comprising a central part (2) and a peripheral part (3), and a voice-coil device (9, 10) coupled to the central part (2). The ratio S2/S1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml&  S2/S1 </= alpha mu  rho  &Uml&  6, where S1 and S2 are the surface areas of the central part (2) and the peripheral part (3) respectively. The ratio m2/m1 complies with the relationship 0.5 </= alpha  mu  rho  &Uml& m2/m1 </= alpha mu  rho  &Uml&  8 where m1 and m2 are the mass of the central part (2) and the voice-coil device (9, 10) and the mass of the peripheral part (3) respectively. Further, the compliance imposed on the diaphragm by the space (6, 6') defined by the diaphragm (2, 3) and the chassis (4) and/or the magnet system (7) is smaller than the compliance of the diaphragm itself (Fig.1). Thus it is possible to realise a car loudspeaker which has a specific dip in its frequency response characteristic P (Fig. 2a), measured in an anechoic room.

Abstract: A multilayer semiconductor structure, formed of two or more separate layers of different materials can be selectively intermixed so as to become compositionally modified, such that the distinction between the different original materials is lost, at least partially. This intermixing process employs irradiation with a pulsed or rapidly scanned laser or electron beam, generally at ambient conditions of temperature and pressure, at energy levels which avoid physical damage to the layered structure. The intermixing may be more complete when multiple pulses from the laser or electron beam are employed.
