Title: A coin apparatus
Inventor: CLARK PAUL
IPC: G07D9/00
Filed: 2020-04-08
Abstract: Coin handling apparatus 1 comprises: coin reservoir 2 including coin output aperture 3; coin output conduit 4 adjacent to and in communication with the coin output aperture 3; and coin separating mechanism 5 between coin output aperture 3 and coin output conduit 4. The coin separating mechanism 5 comprises at least one gate member 9 including a pair of opposing resiliently biased support posts 10. At least one of the pair of support posts 10 reciprocates within the magnetic field of a proximal inductor. The inductor preferably has at least one support post receiving duct 21 and upper and lower coil arrangements 12, 13. As a coin 17 exits the separating mechanism under the gate 9, the gate is forced upwards against the biasing force. The gate movement raises the post 10 within the inductor coils 12, 13, inducing a current in the coils. The induced signal is communicated to a controller 15 via a connection tab 14. The controller is calibrated to convert the received signal to a value indicative of the thickness of the coin, which can be used to aid coin authentication.

Title: Classifying colors of objects in digital images
Inventor: SCOTT COHEN
IPC: G06T7/90
Filed: 2020-04-20
Abstract: Method of classifying an object’s colour comprising: identifying colour similarity regions 314, 414, 416 within multidimensional colour space 310; identifying an object in an image 502; mapping pixels of the identified object into multidimensional colour space 506, 508; generating object colour matching scores based on the mapped pixels and colour similarity regions; and classifying the object’s colour based on matching score. The object image may be down-sampled. Colour similarity areas may be generated by grouping alternative versions AC1-4 of a colour QC. Alternative colour versions may be generated by: converting colour into a different colour model (e.g. HSL, HSV, CMYK); modifying attributes (e.g. brightness, hue, saturation); and converting the modified colour back into the first colour model. Colour matching score may be based on distances between mapped pixels and colour points QC, AC1-4. Mapped pixels may be valid if within a threshold distance of the points 508 and a colour match determined if a threshold number of pixels are valid. When multiple instances of an object are detected, ones that fail to satisfy the minimum colour matching threshold may be filtered out. The above method may be used to detect a coloured object within image(s) and automatically edit said object.

Title: Drive circuit for a brushless motor
Inventor: STEPHEN GREETHAM
IPC: H02P27/16
Filed: 2020-12-03
Abstract: Brushless motor drive circuit, comprising: a bridge converter of bidirectional switches SW1-4 connected to the motor’s phase winding 21; and a controller 38 that configures the switches states (Figs. 4-8,11). Bidirectional switches have four states (Fig.3): ON, bidirectionally conductive; D1, conductive in a first direction; D2, conductive in a second direction; and OFF, non-conductive. A first configuration configures a first pair of bidirectional switches as ON and second pair as OFF (Fig.6a), thereby allowing current to freewheel. A second configuration changes a switch in the OFF state to a diode state (Fig.6b). A third configuration changes an ON switch, in the same arm as the switch in the diode state, OFF (Fig.6c), thereby exiting the freewheeling current mode. A fourth configuration may change the switch in the diode state ON (Fig.6d). A fifth configuration turns all the bidirectional switches to the OFF state during a zero current. The controller may receive a signal indicative of a voltage polarity and chooses a diode state D1, D2 dependent thereon. The arrangement removes the need for a rectifier and prevents reversal of current due to back EMF.
