| 20090047995 | PORTABLE COMMUNICATION DEVICE HAVING A DUAL CAMERA MODULE WITH A COMMON IMAGE SENSOR ELEMENT - A portable communication device is equipped with a dual camera module having a first or main camera module, a second or video telephony camera module and a common image sensor element configured to receive images from the first and second camera modules. The dual camera module includes image-shifting optics configured to shift images from the second camera module onto a portion of a common image sensor such that images from the main camera module may be received by a first or main portion of the common image sensor and images from the second camera module may be received by a secondary portion of the common image sensor. | 02-19-2009 |
| 20090256825 | PEN STYLUS ENABLED CAPACITIVE TOUCH SYSTEM AND METHOD - Described is a capacitive touch screen apparatus. An indium tin oxide (ITO) ground screen covers and protects an optical display. One or more support structures are secured atop the ground screen layer. A first capacitance sensing patterned ITO trace layer is secured atop the support structures such that an air gap exists between the layers. A second capacitance sensing patterned ITO trace layer can be secured atop the first patterned ITO trace layer. A pointed object brought into contact with the outermost patterned ITO trace layer will deform the surface and penetrate a portion of the air gap sufficiently to register a change in capacitance at the point of contact. A protective transparent film layer covering the outermost patterned ITO trace layer can be utilized to protect the surface of the ITO layer from damage. The ITO layers are electronically coupled with a controller capable of sensing changes in capacitance. | 10-15-2009 |
| 20100013763 | METHOD AND APPARATUS FOR TOUCHLESS INPUT TO AN INTERACTIVE USER DEVICE - A plurality of light sources is mounted on a housing of an interactive user device. The sources are spaced from each other in a defined spatial relationship, for example in a linear configuration. At least one light sensor is also positioned at the surface of the housing. The light sensor senses light that is reflected from an object placed by the user, such as the user's finger, within an area of the light generated by the light sources. A processor in the user device can recognize the sensed reflected light as a user input command correlated with a predefined operation and respond accordingly to implement the operation. | 01-21-2010 |
| 20100039372 | MOBILE DEVICE DISPLAY IMPLEMENTATION - A mobile communication device contains a plurality of displays. A control module and one of the displays is contained by a first housing. Another housing, bearing a second display, is slidably engageable with the first housing. An optical data transmission mechanism is coupled between the control module and the second display. Data generated by the control module can be converted to optical signals and transmitted through the optical transmission path for control of the second display. | 02-18-2010 |
| 20100123658 | PORTABLE COMMUNICATION DEVICE HAVING A TOUCH-SENSITIVE INPUT DEVICE WITH NON-LINEAR ACTIVE AREAS - A portable communication device includes a touch-sensitive input device that is configured to include a substantially V-shaped active area. The portable communication device is configured to facilitate character selection and navigation by sensing the user's thumb position on and movement along the substantially V-shaped active area. The portable communication device is configured to provide keypad functionality via the touch-sensitive input device without a graphical representation of character keys and/or navigation keys represented on the touch-sensitive input device. | 05-20-2010 |
| 20110117863 | COMMUNICATIONS CIRCUITRY FOR AN ELECTRONIC DEVICE - The control of an antenna tuner for a portable electronic device includes closed loop tuning when sufficient transmit power is present. The closed loop tuning commences using a predetermined antenna tuner configuration for an operational band and device state. The closed loop tuning may be constrained by a tuning range associated with the predetermined antenna tuner configuration for the operational band and device state. Also, when transmit power is low or when a transceiver is in a receive only state, open loop tuning may be conducted by placing the antenna tuner in the predetermined (or default) configuration for the operational band and phone state. | 05-19-2011 |
