Patent JP-H09500473-A (JP)
IPC: G06V30/10
Filed: 1995-05-08
Abstract: The present invention determines whether two discrete continuous segments of handwritten input S1 (210) and S2 (220) form part of the same handwritten input or are part of more than one, separate handwritten inputs. The present method calculates one or more substantially parallel distance disposed substantially parallel to the writing access (210) and compares these distances to one or more predefined thresholds. The predefined thresholds specify minimum distance measures which must be exceeded by the substantially parallel distances for the discrete continuous segments to be judged as belonging to separate segments of handwritten input.

Title: Beverage can insert; capsule for generating foam when can is opened has a resiliently deformable wall section
Inventor: REYNOLDS ANDREW JOHN
IPC: B65D85/73
Filed: 1994-09-28
Abstract: A sealed beverage can has fitted therein a capsule (10) forming a secondary chamber within the can, the capsule having an associated standpipe (12) apertured at (14) beneath the capsule and terminating at its upper end (16) just below a deformable roof (18) of the capsule, thereby to form an openable and closable valve at the upper end of the tube, whereby communication between the interior of the capsule and the contents of the can is restricted until at least after the can is inverted during pasturisation, whereafter pressurised gas in the gas headspace is able to enter the capsule through the said aperture after the said valve has opened. The restrictor may comprise a controlled leak across the valve which permits the slow ingress of fluid into the capsule. Alternatively at least part of the wall of the capsule is formed from gas permeable material, the permeability of which is such as to restrict the ingress of gas for a sufficient length of time as to prevent a balancing of the pressures to occur until at least after pasturisation has begun.
