|20100201650||CAPACITIVE PROXIMITY TACTILE SENSOR - A novel capacitive proximity tactile sensor is formed by an electrode layer and a compressible non-conductive layer. Positioning a conductive object in contact with the sensor and applying contact force onto the sensor surface allows for both detecting the location of touch (as in traditional proximity sensors) as well as measuring contact force (as in tactile array sensors) due to a capacitance-measuring sensor formed between the electrode layer and the object with the compressible non-conductive layer therebetween. Useful applications of the sensor include input device for consumer electronic item, flexible and thin weight scale, shoe insole for monitoring pressure distribution of a foot while walking, pressure-monitoring seat cushion and others.||08-12-2010|
|20100013775||ELECTRONIC DEVICE HOUSING WITH INTEGRATED USER INPUT CAPABILITY - An electronic device housing with a seemless user input zone that measures the level of force applied by the user is described. It is particularly advantageous when used with small hand-held consumer electronic devices such as mobile phones, PDAs, game—and media players. A housing for an electronic device includes a seamless user input zone defining a contact force-sensitive deformable area. A capacitance sensor is formed between the conductive inside surface of the housing and the electrode of the rigid base facing that inside surface. Linear support means such as columns support the housing away from the rigid base defining an air gap. Capacitance measurement circuit is deployed to detect the location and progressively increasing levels of force applied by the user onto the housing and send a user input signal to the electronic device.||01-21-2010|
|20090124937||VISUALIZATION OF VALUES OF A PHYSICAL PROPERTY DETECTED IN AN ORGANISM OVER TIME - A system for visually indicating, in real time or post hoc, values of a physical property detected over a period of time along a dimension of an organism to a user on a temporal plot and a profile plot, either individually or concurrently. The detected values may be visually indicated on the temporal plot using any of a variety of techniques, including, but not limited to, a contour technique, a line trace technique or a mesh plot technique. Further, the detected values may be visually indicated on the profile plot using any of a variety of techniques, including, but not limited to a contour technique, a line trace technique or a histogram technique. To provide a finer spatial resolution, values may be interpolated for locations between the locations at which values were detected, and these values may be displayed on the temporal plot and the profile plot.||05-14-2009|
|20090033341||CAPACITIVE TACTILE TILE SENSOR - A capacitive tile tactile sensor is described and includes several groups of individual sensors each controlled by a dedicated IC. Individual sensors are formed by sensing electrodes on one side of the sensor and a single ground electrode on the other side, the ground electrode is separated from the sensing electrodes by a compressible dielectric layer. A single electrical connection between the ground electrode and the sensing electrode layer allows for routing of all electrical connections including individual electrodes and a ground electrode to appropriate ICs within the same layer using conductive ink or other similar techniques. Stand-alone configurations are described as well as those adapted for communicating with outside control means including a personal computer. Arranging groups of sensors in parallel with each other creates a matrix of sensors while arranging them along a single line creates a linear strip sensor. Using off-the-shelf capacitance-sensing ICs to control a limited number of capacitance sensors allows reducing the number of electrical connections to the sensor array and increasing its reliability.||02-05-2009|
