20120090757 | FABRICATION OF TOUCH, HANDWRITING AND FINGERPRINT SENSOR - Fabrication methods for combined sensor devices include substantially transparent substrates and materials to increase the optical performance of underlying displays. A substantially transparent elastomeric material may be disposed between the substantially transparent substrates. Some fabrication processes utilize flexible substrates for at least a portion of the sensor device, and lend themselves to roll-to-roll processing for low cost. | 04-19-2012 |
20120092127 | MULTIFUNCTIONAL INPUT DEVICE FOR AUTHENTICATION AND SECURITY APPLICATIONS - This disclosure provides systems, methods and apparatus for a combined sensor device. In some implementations, the combined sensor device may enable a single touchscreen to perform additional functions such as handwriting input and fingerprint recognition. In some implementations, these multiple features allow increased security through user authentication, and allow better capture of handwriting and a more interactive approach to user interfaces. A handheld mobile device such as a cell phone with the combined sensor device can enable an array of applications, such as using the mobile device as a gateway for user authentication to enable transactions and physical access; using the handwriting input function for signature recognition and transmittal for transaction applications; and/or using the handwriting input feature to automatically capture notes and other documents of students in an academic setting or employees in a corporate setting. | 04-19-2012 |
20120092293 | CONTROLLER ARCHITECTURE FOR COMBINATION TOUCH, HANDWRITING AND FINGERPRINT SENSOR - A separate control system may be configured for a combined sensor device. Alternatively, at least part of the control system may be included in another device, such as a processor of a mobile device. Software for handwriting, touch and fingerprint detection may be included in the control system. Low, medium and high resolution may be obtained with a single combined sensor device by scanning a subset of the sensels, or by aggregating lines or columns. Power consumption may be reduced by aggregating sensor pixels (or rows or columns) electrically using the controller, so that they perform as a low power small array until higher resolution with a larger array is needed. Power consumption may be reduced by turning off portions or all of the sensor device, turning off parts of the control system, and/or employing first-level screening at a reduced frame rate. | 04-19-2012 |
20120092294 | COMBINATION TOUCH, HANDWRITING AND FINGERPRINT SENSOR - This disclosure provides systems, methods and apparatus implementations of a display device with a cover glass apparatus that serves as a single or multi-touch sensor, as a handwriting (or note capture) input device, and in some configurations as a fingerprint sensor. Sensor functionality and resolution can be tailored to specific locations on the cover glass apparatus. In some such implementations, the area in which the fingerprint sensing elements are located may provide not only fingerprint detection, but also handwriting and touch functionality. In some other implementations, the fingerprint sensor may be segregated into a separate, high-resolution zone that only provides fingerprint functionality. | 04-19-2012 |
20120092324 | TOUCH, HANDWRITING AND FINGERPRINT SENSOR WITH ELASTOMERIC SPACER LAYER - Use of a compliant, elastomeric layer between upper and lower substrates of the combination sensor can increase the sensitivity to applied pressure or force from a stylus, while increasing the lateral resolution for a given sensel pitch. The elastomeric material may have an index of refraction that is substantially similar to that of the upper and lower substrates. The elastomeric material may include open regions for the inclusion of force-sensitive resistors. With careful selection of the elastomeric and FSR materials, the loss of transmissivity that can accompany air gaps can be minimized. | 04-19-2012 |
20120092350 | WRAPAROUND ASSEMBLY FOR COMBINATION TOUCH, HANDWRITING AND FINGERPRINT SENSOR - This disclosure provides systems, methods and apparatus for a combined sensor device. In some implementations, a combined sensor device includes a wrap-around configuration wherein an upper flexible substrate has patterned conductive material on an extended portion to allow routing of signal lines, electrical ground, and power. One or more integrated circuits or passive components, which may include connecting sockets, may be mounted onto the flexible layer to reduce cost and complexity. Such implementations may eliminate a flex cable and may allow a bezel-less configuration. | 04-19-2012 |
20130050155 | GLASS AS A SUBSTRATE MATERIAL AND A FINAL PACKAGE FOR MEMS AND IC DEVICES - This disclosure provides systems, methods and apparatus for glass packaging of integrated circuit (IC) and electromechanical systems (EMS) devices. In one aspect, a glass package may include a glass substrate, a cover glass, one or more devices encapsulated between the glass substrate and the cover glass, and bond pads configured to attach to a flexible connector and in electrical communication with an encapsulated device. In some implementations, a flexible connector may be used to electrically connect a device within the glass package to an electrical component, such as an integrated circuit (IC) device or PCB, outside the glass package. | 02-28-2013 |
20130162657 | VERTICALLY ETCHED FACETS FOR DISPLAY DEVICES - This disclosure provides systems, methods and apparatus for masked reflective structures which can be integrated into display devices. In one aspect, masks and etch leading layers can be used to control the etching of a stack of layers to form masked reflective structures having a desired profile. In particular, tapered edges at a particular angle can be formed, and the resulting structures used in a roll-to-roll process to fabricate a device component. | 06-27-2013 |
20130278542 | TOUCHSCREEN WITH BRIDGED FORCE-SENSITIVE RESISTORS - A touch sensor may include a digital resistive touch (DRT) sensor architecture that is substantially free of air gaps. The DRT touch sensor may include a layer of force-sensitive resistor (FSR) material on an array of row and column electrodes. The electrodes may be formed on a substantially transparent substrate. Near the intersection of each row and column, one or more thin transparent patterned conductive bridges may be situated above the FSR. The conductive bridges may be configured for electrical connection with row and column electrodes when force is applied to the conductive bridge or surface of the touch sensor. Some touch sensors may include both DRT and projected capacitive touch (PCT) functionality. | 10-24-2013 |
