20130201153 | Biometric Scanner Having A Protective Conductive Array - A biometric scanner having a sensor and an array of conductive strands is disclosed. The sensor has at least one sensor electrode, and that sensor electrode may be a capacitance sensor, an electric field sensor, or an electroluminescent sensor. The array may have an electrical insulating material between adjacent ones of the conductive strands. The array serves to protect the sensor, and conduct through the array information about the electrical characteristics of a biometric object. | 08-08-2013 |
20130201134 | Ultrasonic Touch Sensor With A Display Monitor - A touch screen monitor having a display monitor and an ultrasonic device. The ultrasonic device may include a sensor array using piezoelectric sensors to detect the surface topology of a biological or other object that is in contact with a surface of the display monitor. The display monitor may be a LCD or LED monitor. | 08-08-2013 |
20130200907 | System And Method Of Using An Electric Field Device - A biometric scanner having an electric field device and a method of using that scanner are disclosed. The electric field device (a) has no electric field generator or an electric field generator that is prevented from providing an electric field to a biometric object, such as a finger, and (b) has an electric field sensor array comprised of a plurality of electric field sensors. Capacitance readings from the sensor array are used to generate values that are attributed to locations corresponding to the sensors. | 08-08-2013 |
20120206585 | Biometric Scanner With Waveguide Array - Devices and methods of creating an image of a biological object are disclosed. In one embodiment of the invention there is a plane wave ultrasonic pulse generator, an ultrasonic wave manipulation device, an ultrasonic detector and an image generator. In a method according to the invention, a biological object is imaged by emitting an unfocussed ultrasonic energy wave front, reflecting at least a portion of the ultrasonic energy wave front from the object, altering a direction of the ultrasonic energy, detecting that energy, and using the detected energy to create an image of the object. | 08-16-2012 |
20120026117 | Device And Method Of Controlling A Computer Using Centroids - A computer control system and a method of controlling a computer are disclosed. One such system includes an area-array sensor and a processor. The processor may have a navigation mode, and when set to this mode, the processor is configured to execute certain tasks. Those tasks may include acquiring a first information set and acquiring a second information set from the sensor. The first information set may represent reflected energy received by the sensor at the first time and the second information set may represent reflected energy received by the sensor at the second time. The first information set indicates a first contact area corresponding to that portion of an indicator object (such as a finger or stylus) which contacts the platen at the first time, and the second information set indicates a second contact area corresponding to that portion of the indicator object which contacts the platen at the second time. Centroids of the contact areas are used to determine a navigation control measurement that may be used to control a computer. | 02-02-2012 |
