Abstract: A lighting stage includes a plurality of lights that project alternating spherical color gradient illumination patterns onto an object or human performer at a predetermined frequency. The lighting stage also includes a plurality of cameras that capture images of an object or human performer corresponding to the alternating spherical color gradient illumination patterns. The lighting stage also includes a plurality of depth sensors that capture depth maps of the object or human performer at the predetermined frequency. The lighting stage also includes (or is associated with) one or more processors that implement a machine learning algorithm to produce a three-dimensional (3D) model of the object or human performer. The 3D model includes relighting parameters used to relight the 3D model under different lighting conditions.

Abstract: An electronic driver circuit for comnmunicating a logic value along a conductor (12) from one part of a system (10) to another (14) by representing each of two logic values by one of two logic levels (VDD, Vss).A capacitor (CR1) reduces ground and power reference differences between a chip containing the driver and the board on which it is mounted. The capacitor also provides power and ground decoupling. According to another aspect, a controlled slew rate ramp initiates an incident or outbound wave or turn-on and circuits are described for this. The time taken to complete the controlled slew rate ramp can be adjusted. The arrangements allow reduced power consumption, whilst at the same time producing desirable signal characteristics.

Abstract: A vehicle drum brake has a shoe mounted on a back plate, one end of the shoe engaging an actuator and the other end engaging an abutment. To avoid the use of a fluid pressure control valve to vary the braking effort of the brake in dependence upon vehicle loading, the abutment is in the form of a roller which engages an arcuate member on the shoe, the roller being movable laterally of the shoe to vary the braking effort for a given actuating force. The roller may be connected to a pivoted lever which is rotatably mounted in the back plate and which is connected to a sprung part of the vehicle by a linkage. Movement of the sprung part due to changes in vehicle loading rotates the lever and moves the roller.

Abstract: In a disc brake including pad assemblies for engagement with opposite faces of a rotatable disc and a clamp assembly extending over the peripheral edge of the disc, the clamp assembly comprises pressure plates interconnected by spaced parallel limbs passing through superimposed openings in the plates and interconnected at one pair of adjacent ends by a bridge piece which acts on one of the pressure plates.

Abstract: An automatic slack adjuster assembly is provided in or for a vehicle internal shoe drum brake of the duo-servo type having primary and secondary shoes located within a rotatable drum so that the primary shoe is carried round with the drum when the brake is applied, the slack adjuster assembly being located in a housing between adjacent ends of the shoes and including a thrust member which engages the ends of the shoes and transmits thrust on the primary shoe to the secondary shoe when the brake is applied. The adjuster assembly includes a sensing mechanism which senses relative movement between the thrust member and the housing and controls an energy-storing clutch mechanism which is connected to an adjuster and operates the adjuster to increase the effective length of the thrust member when the torque generated by the stored energy force is greater than the torque generated by the force applied to the thrust member from the shoe ends.

Abstract: This invention relates to the synthesis of diamond by subjecting a carbon-containing composition substantially free of carbon-hydrogen covalent bonds to conditions of temperature and pressure such as to cause decomposition of the composition to release carbon atoms or groups of carbon atoms and effect conversion of the released carbon atoms or groups of carbon atoms into diamond. The preferred compositions are halogenated compounds, particularly hexachlorobenzene, hexachloroethane and tetrachloroquinone.
