Abstract: Disclosed is a means for adjusting color gamut data associated with a digital media file to compensate for changing ambient light conditions at a display screen. Ambient light conditions at the display screen are detected using a light sensor and converted into ambient light data. Alternate color gamut data is then selected according to the current ambient light data from a color gamut look-up table that contains optimized color gamut data for a variety of ambient light data associated with the digital media file. Display correction parameters are then determined based on the alternate color gamut data. The display correction parameters are applied to present a more optimal rendition of the digital media file. The light sensor periodically re-detects the ambient light conditions so that any changes can be re-processed to update a rendition of the digital media file as it is displayed.

Abstract: A handheld, personal electronic device includes a handheld device housing. An electronic component is disposed in the handheld device housing. A fiber optic cable is routed through the handheld device housing and is operably connected to the electronic component to permit transmission of optical signals to and/or from the electronic component via the fiber optic cable. The device may be a mobile wireless communications device.

Abstract: A voice activated method of establishing a Push-to-Talk (PTT) connection from a mobile phone is disclosed. The mobile phone user presses and holds a PTT key on the mobile phone. The user then speaks the name of a contact. The mobile phone recognizes the name of a contact that has been spoken and associates the recognized name with an entry in the mobile phone's memory. The mobile phone then displays the name of the contact on its display. The user can then speak additional contact names or can release the PTT key. Upon release of the PTT key, the mobile phone initiates a PTT connection from the mobile phone to the contact(s) displayed. The mobile phone uses PTT contact data in the mobile phone's memory associated with the contact name to make the PTT connection. The name of a contact may also comprise a group name that is associated with multiple contacts.

Abstract: A method and apparatus improves the visibility of information displayed on a portable electronic device display in various ambient lighting conditions. The portable electronic device measures the ambient light associated with the display and adjusts the display based on the measured ambient light to improve the visibility of the displayed information. In an exemplary embodiment, light detection electronics detect the ambient light associated with the display. A light processor processes the raw data to determine the measured ambient light based on the detected ambient light. A display controller of the portable electronic device adjusts the display based on the measured ambient light. An exemplary display controller may adjust the size of the displayed information, a backlight intensity of the display, or a display contrast based on the measured ambient light.

Abstract: A microelectric module including a circuit substrate having one or more covers or electromagnetic shields disposed thereon. To secure the covers or electromagnetic shields to the circuit substrate, and provide an electrical contact with an underlying ground pattern, a thin plastic film is extended over the covers or electromagnetic shields and the circuit substrate. This film is subjected to heat, causing it to shrink and effectively provide a controlled force that acts to hold and lock the covers or electromagnetic shields to the circuit substrate. Thus the heat-shrunk film mechanically secures the covers or electromagnetic shields to the circuit substrate and at the same time seals the microelectric module formed.
