Publication number: 20140089865Abstract: A gesture input application adapted for translating gesture input into font characters. A web application, such as a webpage, embedded with the gesture application is served over a network to one or more computing devices for local execution of the gesture put application by a web browsing software on the computing device. The web application includes rules for styling the webpage on the computing device and the source code for the gesture input application. The computing device executing the web application with the web browsing software receives from a user a gesture input and translates the gesture input into at least one standard font character as an input to the web application.Type: ApplicationFiled: August 23, 2013Publication date: March 27, 2014Applicant: Co-operwrite LimitedInventors: Geoffrey Norman Walter GAY, Billy MOON

Publication number: 20140085311Abstract: A method includes receiving from a user a gesture input and correlating the gesture input with a first animated font character in an animated font character library. As the gesture input continues, the first animated font character morphs into a second animated font character to give a visual appearance to the user of a character forming on the display device. In this regard, the first animated font character and the second animated font character can be component animated font characters that are each segments of a completed animated font character that is formed in step with the gesture input.Type: ApplicationFiled: August 23, 2013Publication date: March 27, 2014Applicant: Co-operwrite LimitedInventors: Geoffrey Norman Walter GAY, Billy MOON

Publication number: 20130067877Abstract: An air cleaning filter for an air conditioning system comprising a rigid frame having a length, a width and a depth, to which flexible filter material is mounted, the filter material being of greater cross-sectional area than the rigid frame, and including at least two peaks and one trough therein, the maximum peak-to-trough amplitude of which is greater than the depth of the rigid frame. The length and width of the filter are adapted so as to be positioned, in use, in a direction that is substantially perpendicular to the direction of airflow of the air being filtered, whilst the depth thereof is adapted so as to be positioned, in use, in a direction that is substantially parallel to said direction of airflow.Type: ApplicationFiled: September 13, 2012Publication date: March 21, 2013Inventors: George Griffiths, Geoffrey Norman Walter Gay

Patent number: 7014688Abstract: A particle precipitation device for removing particles entrained in a gas stream includes an array of passages through which a gas stream can be directed relatively freely. The passages are provided between plastics walls adapted to create an electrical field within the array. The plastics walls may have areas of conductive material in contact therewith. High and low electrical potentials alternately applied to isolated areas of the conductive material provide charged sites in the array for collecting particles from the gas stream. Alternatively, the plastics walls may have electret properties.Type: GrantFiled: June 8, 2004Date of Patent: March 21, 2006Assignee: Darwin Technology LimitedInventors: George Griffiths, Geoffrey Norman Walter Gay

Patent number: 6647145Abstract: An apparatus and method for inputting a hand-generated character into a computer. A user draws a character using a drawing apparatus. As the user draws, movement of the apparatus and characteristics of such movement are detected. The apparatus generates a code for the character being drawn as a time dependent sequence of signals by comparing the characteristics of the movement as the character is drawn with a predetermined set of characteristics, with each signal corresponding to the predetermined characteristic closest to the actual characteristic detected at each successive step of movement. The apparatus provides visual feedback to the user by displaying in sequence each component of a character that is being drawn positionally independently of the movement of the drawing apparatus.Type: GrantFiled: July 23, 1999Date of Patent: November 11, 2003Assignee: Co-Operwrite LimitedInventor: Geoffrey Norman Walter Gay
