Publication number: 20080048679Abstract: Methods, systems and devices are described for detecting a measurable capacitance using sigma-delta measurement techniques. According to various embodiments, a voltage is applied to the measurable capacitance using a first switch. The measurable capacitance is allowed to share charge with a passive network. If the charge on the passive network is past a threshold value, then the charge on the passive network is changed by a known amount for a sufficient number of repetitions until the measurable capacitance can be detected. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to a button, slider, touchpad or other input sensor.Type: ApplicationFiled: October 30, 2007Publication date: February 28, 2008Applicant: SYNAPTICS INCORPORATEDInventors: Kirk HARGREAVES, Joseph REYNOLDS, David ELY, Julian HAINES

Publication number: 20080042660Abstract: Methods, systems and devices are described for detecting a measurable capacitance using charge transfer techniques. According to various embodiments, a charge transfer process is performed for two or more times. During the charge transfer process, a pre-determined voltage is applied to the measurable capacitance, and the measurable capacitance is then allowed to share charge with a filter capacitance through a passive impedance that remains coupled to both the measurable capacitance and to the filter capacitance throughout the charge transfer process. The value of the measurable capacitance can then be determined as a function of a representation of a charge on the filter capacitance and the number of times that the charge transfer process was performed. Such a detection scheme may be readily implemented using conventional components, and can be particularly useful in sensing the position of a finger, stylus or other object with respect to an input sensor.Type: ApplicationFiled: October 26, 2007Publication date: February 21, 2008Applicant: SYNAPTICS INCORPORATEDInventors: David ELY, Paul ROUTLEY, Joseph REYNOLDS, Julian HAINES, Kirk HARGREAVES

Publication number: 20070073732Abstract: Tasks can be done on a network of multiple computers interconnected by communication links. At each of the computers, Knowbot programs may be received and transmitted on the communication links, and may be stored and created; and execution of the tasks associated with the Knowbot programs may be advanced. Each Knowbot program includes a globally unique identifier; navigation information defining a route through the network; and information concerning a task to be done. Knowbot programs may interact with each other and with other network resources. Authenticated Knowbot service stations and Couriers may be used to protect data as well as control its application in the network environment according to stated terms and conditions.Type: ApplicationFiled: November 1, 2006Publication date: March 29, 2007Inventors: Robert Kahn, Vinton Cerf, David Ely

Patent number: 7133793Abstract: A calibration system is provided for use in generating calibration data for calibrating an X-Y digitiser. The calibration system uses an alignment head having an array of magnetic field generators which are for alignment with the X-Y digitiser. Each of the magnetic field generators is individually drivable so that calibration data can be obtained for different positions on the X-Y digitiser corresponding to the positions of the magnetic field generators in the array.Type: GrantFiled: July 23, 2004Date of Patent: November 7, 2006Assignee: Synaptics (UK) LimitedInventors: David Ely, Gareth McCaughan

Publication number: 20060136923Abstract: A method for use in a distributed system for processing a knowbot program that has the ability to move from node to node in the distributed system. In the method, an operating environment in each of the nodes provides service facilities useful to the knowbot program. And,.in the operating environment, a supervisor process is run that enables the knowbot program to make use of the service facilities but does not permit direct access by the knowbot program to facilities of the operating environment.Type: ApplicationFiled: December 22, 2005Publication date: June 22, 2006Inventors: Robert Kahn, David Ely, Guido Van Rossum, Theodore Strollo, Barry Warsaw

Publication number: 20050174259Abstract: An x-y digitising system is described which operates with a resonant stylus. The x-y digitising system includes an excitation winding for energising the resonant stylus and a number of sensor windings for receiving a signal re-radiated by the resonant stylus when energised. At least one of the excitation winding and the sensor winding is arranged to have its effective magnetic axis non-othogonal to the working area of the x-y digitising system. With this arrangement, improved energy transfer between the x-y digitising system and the resonant stylus can be achieved and/or improved position measurement accuracy can be obtained.Type: ApplicationFiled: June 5, 2003Publication date: August 11, 2005Inventor: David Ely
