Abstract: There is a method of computing a stylized, animatable representation of a subject from a family of stylized animatable representations. The method comprises: accessing a realistic representation of the subject; computing a mesh mapping using a model that was formed using a data set of training examples which pair realistic representations of other subjects with instances of the family. The method also comprises applying the mesh mapping to the realistic representation of the subject to produce a target mesh; and selecting the stylized animatable representation from the family, by assessing closeness of the target mesh with instances of the family.

Abstract: In various examples there is an apparatus for computing an image depicting a face of a wearer of a head mounted display (HMD), as if the wearer was not wearing the HMD. An input image depicts a partial view of the wearer's face captured from at least one face facing capture device in the HMD. A machine learning apparatus is available which has been trained to compute expression parameters from the input image. A 3D face model that has expressions parameters is accessible as well as a photorealiser being a machine learning model trained to map images rendered from the 3D face model to photorealistic images. The apparatus computes expression parameter values from the image using the machine learning apparatus. The apparatus drives the 3D face model with the expression parameter values to produce a 3D model of the face of the wearer and then renders the 3D model from a specified viewpoint to compute a rendered image. The rendered image is upgraded to a photorealistic image using the photorealiser.

Abstract: A computer system is provided that includes an input system and a processor that may be configured to control a virtual manipulator based on input data received from the input system. The processor is further configured to determine an initial state of a system that includes at least an initial state of the virtual manipulator and an initial state of a virtual object, detect at least one contact point between a portion of the virtual manipulator and the virtual object. The processor is further configured to calculate a subsequent state for the virtual object that minimizes a set of energies or residuals defined in terms of the one or more positional quantities determined for the initial state of the system and the one or more positional quantities determined for the subsequent state of the system using a position-based energy minimizing function.

Abstract: A non-positive-displacement machine (10), particularly a turbomachine for producing a mass flow, having a central housing part (11) inside which a turbine shaft is mounted. A turbine housing is mounted on the central housing part (11) on a turbine side and a compressor housing is mounted on the central housing part (11) on a compressor side. The spiral channels (17, 18) required for the compressor side and for the turbine side can be arranged in a partial area inside the covers (15, 16) and at least in one partial area inside the central housing part (11). This permits the contours, which are required for the spiral channels (17, 18) and which are geometrically complex, to be constructed in the central housing part (11).

Abstract: A radio frequency (RF) driven plasma ion source has an external RF antenna, i.e. the RF antenna is positioned outside the plasma generating chamber rather than inside. The RF antenna is typically formed of a small diameter metal tube coated with an insulator. An external RF antenna assembly is used to mount the external RF antenna to the ion source. The RF antenna tubing is wound around the external RF antenna assembly to form a coil. The external RF antenna assembly is formed of a material, e.g. quartz, which is essentially transparent to the RF waves. The external RF antenna assembly is attached to and forms a part of the plasma source chamber so that the RF waves emitted by the RF antenna enter into the inside of the plasma chamber and ionize a gas contained therein. The plasma ion source is typically a multi-cusp ion source.

Abstract: An edible greeting card includes two edible leaves. Each leaf of the card is imprinted with a message and/or design which is suggestive of a celebratory event and each leaf is individually wrapped in clear plastic. The two leaves are coupled to each other by a hinge which may be formed from a strip of adhesive tape or from a folded cardboard member which embraces an edge of each leaf. The wrapped and hinged leaves are preferably packaged with at least one self-adhesive label upon which the sender may write a personal message and affix the label to one of the leaves. The edible greeting card and the self-adhesive label are preferably packaged in a plastic box which serves as the "envelope" for the greeting card.
