| 20080266425 | METHOD AND APPARATUS FOR ENHANCED DIGITAL IMAGING - A method and digital imaging device, such as a digital camera module, is provided for digital imaging. The method includes the step of determining a signal-to-noise ratio associated with a first pixel location of a plurality of pixel locations and a signal-to-noise ratio associated with a second pixel location of the plurality of pixel locations, and the steps of assigning a first exposure time to the first pixel location in response to the signal-to-noise ratio associated with the first pixel location and assigning a second exposure time different from the first exposure time to the second pixel in response to the signal-to-noise ratio associated with the second pixel location. The method further includes the step of exposing the first pixel location for the first exposure time while exposing the second pixel location for the second exposure time to create a digital image. | 10-30-2008 |
| 20080299927 | SIGNAL STRENGTH INDICATION METHODS FOR USE IN WIRELESS COMMUNICATION DEVICES - Embodiments include signal strength indication methods for use in wireless communication devices. In an embodiment, a method includes producing a default received signal strength indicator (RSSI) using default RSSI determination parameters. The method also includes determining that a received signal strength is inadequate, and producing an alternate RSSI, in response, where the alternate RSSI is produced using at least one alternate RSSI determination parameter that is different from at least one default RSSI determination parameter. In another embodiment, a method includes measuring multiple received signal strengths for multiple received signals from multiple base stations, and producing an alternate RSSI based on a received signal strength measurement for a strongest signal of the multiple received signals. An embodiment of a wireless communication device may include a processing subsystem adapted to perform embodiments of the methods. | 12-04-2008 |
| 20090002529 | METHOD AND APPARATUS FOR ROBUST IMAGE PROCESSING - A method and digital camera module is provided for taking a digital picture of an image. The digital camera module includes a plurality of light sensitive pixel elements, a first memory buffer, a second memory buffer and a controller. The controller is coupled to the plurality of light sensitive pixel elements and the first and second memory buffers and records a first plurality of pixel values representing an image by activating the plurality of light sensitive pixel elements in a first predetermined manner and stores the first plurality of pixel values in the first buffer. The controller then records a second plurality of pixel values representing the image by activating the plurality of light sensitive pixel elements in a second predetermined manner and stores the second plurality of pixel values in the second buffer. The controller further processes the first and second plurality of pixel values in a compressed domain to generate a third plurality of pixel values representative of the image. | 01-01-2009 |
| 20090168684 | BROADCAST MESSAGING IN WIRELESS COMMUNICATION NETWORKS - A method for receiving a broadcast message in a wireless communication device is disclosed. The device receives a broadcast message that has associated therewith a unique message grouping identifier and determines whether the unique message grouping identifier of the received message is equal to a unique message grouping identifier of a previously received message. The device ignores the received broadcast message when the unique message grouping identifier of the received message is equal to the unique message grouping identifier of the previously received message and in some implementations enters sleep mode. | 07-02-2009 |
| 20110025906 | Solid State Shutter Devices and Methods - Disclosed are methods and devices for solid state electronically switched optical shutters of cameras and other devices. The disclosed non-mechanical camera shutter includes an electronically controlled material that provides optical density variation, to transition the shutter from being open to being closed. The layer of electronically controlled material is configured to change from substantially to transparent to substantially opaque, without scattering, by changing the state of the material. The transmittance period is the period of time that the layer changes transmittance from approximately 100% to approximately 0%. Electronic circuitry is in communication with a timing control module that is configured to provide a signal output to a transparent conductive layer proximal to the layer of electronically controlled material to initiate a change in its transmissivity. The described electronically switched optical component would add little or no additional bulk to a small camera. | 02-03-2011 |
| 20120044853 | BROADCAST MESSAGING IN WIRELESS COMMUNICATION NETWORKS - A wireless communication device includes a receiver configured to receive an emergency alert configuration message identifying which sub-message of an emergency broadcast message comprising a collection of sub-messages to be received by the wireless communication device, wherein the wireless communication device is configured to receive only the sub-message of the emergency broadcast message identified by the emergency alert configuration message. | 02-23-2012 |
