IPC: G06T15/06
Filed: 2020-07-14
Abstract: Creating a bounding volume hierarchy (BVH) 530 acceleration structure for a 3D graphical image model by establishing or determining a set or palette of local transformations 540 (e.g. matrices with respect to a local coordinate system of the model), and for each BVH node 521-528 in the model determining a first bounding volume and identifying one of the palette of transformations (e.g. via an index value) associated to the node that maps between the first bounding volume and a second bounding volume 501-518. Preferably the bounding volume hierarchy (BVH) is used for ray tracing when rendering the graphical model. Preferably the models are instances in a larger acceleration structure. In this setting the transformations allow an oriented bounding box (OBB) to be defined by one of a palette of useful transformations (e.g plus or minus 45 degrees) plus an easily specified axis-aligned bounding box (AABB). Preferably, the first bounding volume may be selected from a set of candidate bounding volumes.

Title: A cleaning apparatus for circuit boards
Inventor: RUJIAN SHI
IPC: H05K3/26
Filed: 2021-03-30
Abstract: A cleaning apparatus for circuit boards, a first conveyor (3 in fig 3, is hidden behind 2 in fig 1) delivering the boards to one of at least two cleaning shells 200 held on a motor driven axel mounted to support 50 such that the shells rotate to deliver a cleaned board to second conveyor 1 having weep holes. The shells thus utilise gravity to allow both sides of the board to be brushed by the mechanism in the shells. Between the loading and unloading position of the axel, there is a brush cleaning position. A mechanism inside the shell (figures 5 to 9) moves with the aid of a gear (701 fig 5) mating with fixed internal gear (601 fig 8) to both turn tubes carrying brushes for cleaning the board surface and to move a stop rod down into the shell to lower the board into the shell and past the brushes. The stop rod is fixed to a chain (207 fig 5) running between spaced turntables (205, 206 fig 5) connected to the gear 701. The brushes can be cleaned by cleaning water from discharge tube 53 when the shells are temporarily aligned (not shown) with a second motor driven shaft (100 fig 8) fixed to the support. The shaft drives threaded rods( figs 7, 9) that are located inside the brush tubes and mate with threads inside the tubes to preferably drive the brushes to rotate out of the cleaning space in the shell to a temporary cleaning position. The present invention is able to automatically clean two sides of the circuit board as well as brushes, thereby avoiding a failed cleaning of the circuit board due to dirty brushes.

Title: Forward secrecy in transport layer security using ephemral keys
Inventor: MICHAEL GRAY
IPC: H04L9/40
Filed: 2020-10-29
Abstract: Transport Layer Security (TLS) connection establishment between a client and a server for a new session is enabled using an ephemeral (temporary) key pair. In response to a request, the server generates a temporary certificate by signing an ephemeral public key using the server's private key. A certificate chain comprising at least the temporary certificate that includes the ephemeral public key, together with a server certificate, is output to the client by the server, which acts as a subordinate Certificate Authority. The client validates the certificates, generates a session key and outputs the session key wrapped by the ephemeral public key. To complete the connection establishment, the server applies the ephemeral private key to recover the session key derived at the client for the new session. The client and server thereafter use the session key to encrypt and decrypt data over the link. The ephemeral key pair is not reused.
