A method of data storage includes associating delta colour compression DCC metadata with one or more tiles of graphics data, selecting one or more such tiles that are uniform in colour and hence can be accurately represented by the DCC metadata for that tile, and replacing some or all of the graphics data in one or more selected tiles with different data.

Data storage system and method

A display system for use in a Pepper's Ghost illusion includes a light emissive display, a sensor operable to detect the position of an attachment member of a cone, relative to the light emissive display, and a positioning processor operable to position images, which have been distorted by an inverse of the distortion caused by the reflection of the cone, responsive to the detected position of the cone relative to the light emissive display.

Display method, apparatus and system

A system includes: a receiving unit configured to wirelessly receive a modulated electromagnetic signal leaked by a mains power line, the mains power line carrying a modulated alternating current signal, a demodulator configured to demodulate the modulated electromagnetic signal and extract one or more data signals from the demodulated electromagnetic signal, a processor configured to generate control data based on the one or more data signals, a control unit configured to control one or more actuators based on the control data, a processor configured to generate control data for controlling one or more actuators, and a modulator configured to modulate an alternating current signal of a mains power line using the generated control data to create a modulated alternating current signal, thereby causing the mains power line to leak a modulated electromagnetic signal comprising the control data that is wirelessly detectable.

System and method of robot control

A cone for use in a Pepper's Ghost illusion includes a conical wall of semi-reflective material, and an attachment member for removably attaching the cone to the surface of a light emissive display, and a method of displaying a Pepper's Ghost illusion includes positioning a cone of semi-reflective material onto a light emissive display; and displaying on the light emissive display an image that has been distorted by an inverse of a distortion caused by a reflection of the cone.

A charging apparatus for wireless charging of one or more robotic devices includes a power transmitting unit having a plurality of conducting wires each configured to carry a respective alternating current signal and to generate a time-varying magnetic flux when the conducting wire carries the alternating current signal, a processor configured to detect a presence or an absence of an induction coil of a robotic device within a predetermined distance of a conducting wire and to generate control data based on the result of the detection, and a control unit configured to control at least one of an amplitude and a frequency of each respective alternating current signal supplied to each of the conducting wires based on the control data, where the control unit is configured to increase at least one of an amplitude and a frequency of an alternating current signal supplied to a conducting wire in response to control data indicating the presence of the induction coil within the predetermined distance of the conducting wire.

Apparatus system and method of wireless robot charging

A flood-fill method for parallel implementation includes the steps of receiving an image including first elements having a flood fill source colour to be replaced with a flood fill target colour, and second elements not having the flood fill source colour; dividing the image according to a hierarchical space-partitioning scheme to form cells at a plurality of levels in the hierarchy; detecting the occupancy of each cell by second elements; for any cell having no occupancy by second elements, set a depth elevation value for child cells of that cell to be one greater than the value for that cell, indicating that the flood fill shall navigate levels towards a root cell by the depth elevation amount of a cell whilst only occupying nodes without any second elements, thereby reaching the largest parent cell which can be flood-filled; and filling the flood fill source colour of cells having no occupancy by second elements with the flood fill target colour, thereby modifying the received image.
