Patent number: 9888858Abstract: Devices and systems provide methods for detecting cardiac signals from head or facial biopotential sensors. In one embodiment, a facial biopotential signal is measured by a set of sensors. A processor derives a cardiac signal from the facial biopotential signal. Optionally, heart rate is detected from the cardiac signal. Heart rate variability may be determined and evaluated by the processor to generate warnings or messages from the evaluation. One or more head or facial biopotential electrodes for measuring the facial biopotential signal may be integrated in or at a contact surface of head support structures such as a headgear support or respiratory treatment mask. In some such embodiments a controller of a respiratory treatment apparatus may serve as a cardiac signal detector by processing the facial biopotential signal from the sensors and may make control adjustments or generate warnings based on an evaluation of detected signals.Type: GrantFiled: November 14, 2011Date of Patent: February 13, 2018Assignee: ResMed LimitedInventors: Steven Paul Farrugia, Darius George Chapman

Patent number: 7210540Abstract: A securing arrangement for a tool (7) of an agricultural tillage implement of a type having a tapered interconnection between a socket (5) on the tool and an adaptor piece (3) adapted for mounting onto a tine (1) of the tillage implement. The adaptor piece (3) has a recess (9) which can be an aperture or a pair of transverse arcuate slots (31) for receiving a retaining pin(11). The socket (5) on the tool has notches (15) on its opposed sides and a portion (13) on the retaining pin in use engages into at least one of the notches (15) to prevent disengagement of the socket (5) from the adaptor piece (3). The adaptor piece can be integral with the tine.Type: GrantFiled: November 10, 2005Date of Patent: May 1, 2007Assignee: Osmundson Australia Pty LtdInventors: Graeme Stanley Ward, Thomas George Chapman

Publication number: 20060191628Abstract: A method of making a template for a countertop, the template being usable to form a countertop configured for application to an existing countertop-receiving structure, includes the steps of dimensioning the existing countertop-receiving structure with a plurality of strips of a flexible material and adhering the dimensioned strips of flexible material to one another to form the integrated template. If a rounded or contoured shape for the countertop is desired, the dimensioned strips may be cut to depict this desired design. A kit for making a template for a countertop according to this method includes one or more rolls of a flexible strip material, an adhesive, an adhesive dispenser, a funnel, and a pair of scissors. This method and kit made it easy and efficient to create a countertop template that is lightweight and can be easily rolled up or folded up for storing and shipping.Type: ApplicationFiled: February 28, 2005Publication date: August 31, 2006Inventors: George Chapman, Carolyn Chapman

Patent number: 6323884Abstract: Provided are a method and a software-implemented mechanism for assisting a user of a graphical user interface (GUI) with the task of positioning an input device pointer (or otherwise indicating a position selection) when selecting a GUI element such as a button or other icon. The software identifies those GUI elements which are valid selections for the current application state and so are potentially the next element that the user will interact with. Then a predefined set of characteristics for the identified GUI elements are compared to predict which of these GUI elements will be the next GUI element that the user will interact with. The result of this prediction is indicated by moving the pointer to the position within the GUI of the predicted GUI element or by adding emphasis to the predicted GUI element. The user then decides whether this GUI element is required.Type: GrantFiled: June 21, 1999Date of Patent: November 27, 2001Assignee: International Business Machines CorporationInventors: Colin Leonard Bird, Sydney George Chapman

Patent number: 6278463Abstract: Methods and apparatus are provided for processing digital image data representing first and second images I1 and I2 with overlapping image content to produce digital image data representing a composite image I3 spanning the overlap region O. The method comprises processing image data which corresponds to the overlap region in the first and second images I1 and I2 such that the proportions of first image data and second image data contributing to the overlap region O in the composite image I3 vary along the length L of the overlap region O. Preferred methods include defining a non-straight line J extending along the length of the overlap region O, and performing said processing by reference to said non-straight line J such that the ratio of the proportions of first and second image data contributing to the overlap region O varies for different sections S of the overlap region O along the length L thereof.Type: GrantFiled: July 6, 1999Date of Patent: August 21, 2001Assignee: International Business Machines CorporationInventors: Sydney George Chapman, Brian Michael Collins

Patent number: 6246478Abstract: A reticle for an object measurement system comprises a pattern 10 having a plurality of pairs of contrasting elements in the form of black (11′, 11″ . . . 14′14″) and white (21 . . . 24) wedges. Each black/white wedge pair defines a path towards a pattern origin 19 such that an edge of an object 50 occluding the path causes a change in contrast adjacent an edge point along the path. The pattern has a series of Gray-coded elements 15 associated with each pair of black/white wedges. The Gray-coded elements are indicative of an absolute coordinate of each edge point at which an object edge crosses a path. A series of triangles 16 associated with each pair of black/white wedges, whose absolute coordinates are known, allow a measurement system to provide accurate coordinates for each edge point.Type: GrantFiled: May 25, 1999Date of Patent: June 12, 2001Assignee: International Business Machines CorporationInventors: Sydney George Chapman, Andrew Gordon Neil Walter

Patent number: 6216228Abstract: Provided is a method and a system for automatically controlling display of video or image data in dependence on content classification information which is integrated within the data by means of invisible digital watermarking techniques. A controller decodes the watermarked content codes and then prevents displaying of certain material, by overlaying the display with blanking data, if the codes match certain stored codes which the controller has been set to respond to. The use of invisible digital watermark codes by a controller which operates in response to the watermark codes provides reliable control since the codes are more difficult for unauthorized persons to detect and remove than other embedded codes would be.Type: GrantFiled: October 14, 1997Date of Patent: April 10, 2001Assignee: International Business Machines CorporationInventors: Sydney George Chapman, Julian Hamilton Jones

Patent number: 5774650Abstract: A method and data processing system are disclosed for controlling the access of a plurality users to a computer system connectable over a network to a plurality of computers. The data processing system has facilities for restricting user access to the data processing system which includes a user authentication procedure in which at logon a user's identity is compared with a list of authorized users. In addition, the data processing system has a system-wide profile referenced by all users of the system at logon and temporary access control facilities for temporarily preventing access to the system by a normally authorized user or users. The temporary access control facilities allow a privileged user of the computer system to create a list of temporarily unauthorized users that is referenced by the system-wide profile at logon.Type: GrantFiled: September 1, 1994Date of Patent: June 30, 1998Assignee: International Business Machines CorporationInventors: Sydney George Chapman, Michael George Taylor
