20090066673 | Integrated force sensitive lens and software - A software compensation method that allows a touch sensitive display to be built using low-cost FSR force sensors The compensation method comprises an array of functional compensation modules including filtering, voltage conversion, temperature compensation, humidity compensation, sensor calibration, sensor reading linearization, auto calibration, positioning determination and finally end-user and mechanical calibration. The array of compensation modules can bring system accuracy from a non-compensated average positioning error in the 25% to 50% range, down to aN end-user acceptable range of 0% to 5%. The increased positioning accuracy makes it possible to use FSRs as opposed to traditional piezoresistive based touch screen sensors. | 03-12-2009 |
20090297062 | Mobile device with wide-angle optics and a radiation sensor - A method and device for displaying content using an integral or remote controller for navigating the content based on dynamic image analysis of the motion of the controller, for example, by tilting. The controller is equipped with wide-angle optics and with a radiation sensor detecting either visible light or infrared radiation. The wide-angle optics may be directed towards the user, whereupon the radiation sensor receives useful images through the wide-angle optics. The images include contrast or thermal differences which it make possible to determine in which way the user has moved the controller. In more detail, a tilt angle or a corresponding change can be calculated and then, on the basis of the change, the content shown on a display is altered. The content is, for example, a menu, game scene or a web page. | 12-03-2009 |
20100171691 | VIEWING IMAGES WITH TILT CONTROL ON A HAND-HELD DEVICE - A user interface suitable for use in cellular phones and personal digital assistants (PDAs), PC Tablets, as well as laptops, PCs, office equipment, medical equipment, or any other hand-held electronic device, that allows control of the image on the device display by tilting the device to either change the view in perspective, change the magnification, or both, concurrently, by moving the device. Thus, the tilt of the device controls the angle of view of the image, and moving the device perpendicular to the screen controls the magnification. | 07-08-2010 |
20130342501 | HYBRID FORCE SENSITIVE TOUCH DEVICES - A hybrid touch-screen display that integrates force-based touch-screen technology with any one from among a group of projective capacitive, surface capacitive, resistive, digital resistive, SAW, IR, APR, DST, optical and electromagnetic touch-screen technologies to provide an ability to compensate for non-perfect force transfer. An alternate implementation is also disclosed that employs a single force sensor for relative force measurement in a system in which force is traditionally not measured, here a water dispenser unit. This allows compensation for varying static loads, run-time calibration, and filtering of extraneous loads through firmware. | 12-26-2013 |

20120200789 | INTEGRATED FEATURE FOR FRICTION-LESS MOVEMENT OF FORCE SENSITIVE TOUCH SCREEN - A suspension system for a differential-pressure touch sensitive panel suspended over force sensors, for use in either fixed or mobile devices such as point of sales terminals, kiosks, laptops, monitors, PDAs, cell phones, UMPCs and more. In one embodiment, a number of leaf springs are attached directly to the touch lens at both ends and attached directly to the underlying housing at the center, effectively pulling the leaf spring down at the center into a concave arc. The spring bias preloads the touch lens downward against the force sensors. The leaf springs bring the touch lens into a fixed state in the xy-plane and resist translation; however, the touch lens remains free to float against the bias of the leaf spring(s) without any frictional physical contact along the z-axis. | 08-09-2012 |
