Abstract: A method is set forth for automatically adjusting screen and keypad brightness on a mobile electronic device having a light sensor, display screen and keypad, for optimum legibility under varying lighting conditions, with minimal eye strain and distraction to the user. The method includes obtaining light level samples from the light sensor, and independently adjusting backlight intensity of the display screen and keypad responsive to the light level samples. Preferably, correct screen and keypad adjustments are made responsive to the user pulling his or her handheld device out of its holster notwithstanding non-optimal ambient light detection while the device is being removed from the holster. According to another aspect, the described method allows for ambient light detection in a handheld device where the light sensor and a message notification indicator share a common light pipe.

Abstract: A system and method manages configuration data within a hardware component of a device to support hardware component changes during development or manufacture of the device. A Standardized Virtual Part (SVP) file is formed as a binary file and includes a SVP header that comprises metadata of one of at least schema version, revision numbers, part numbers, creator and description. The SVP file also includes hardware configuration data and a SVP trailer that includes error checking data for data authentication. The SVP file is loaded onto the device during development or manufacture for configuring the hardware component.

Abstract: The disclosure describes a system and method for controlling interfacing parameters for a device when connected to a host. In the system and method, the communications interface is configurable to be in operable connection to a host using a microprocessor in the device having a first bus controller and a second bus controller, the second bus controller external to the microprocessor. The method comprises: establishing an initial connection by the device; conducting negotiations by the device to set a first data transmission rate for the device for the initial connection utilizing a communication bus controller contained in the microprocessor; and after detecting completion of enumeration of the device, re-establishing the connection by the device using the second bus controller in the device that processes the communications at a second transmission rate that is higher than the first data transmission rate.

Abstract: A method of manufacturing a portable computing device, involves the steps of (1) performing one manufacturing step in the manufacture of the portable computing device by interfacing a hardware component with another component of the computing device; and (2) performing a subsequent manufacturing step in the manufacture by (i) identifying the interfaced hardware component from a response received at the another component; and (ii) initializing the identified interfaced hardware component using a device driver associated therewith.

Abstract: A field sequential liquid crystal display maintains its white colour point through compensation values to at least one colour light emitting diode that illuminates the display. The compensation values may be impedances to control the current or pulsing of the current source according to a pulse width modulation technique. A degradation curve may be used to calculate extrapolate the theoretical forward voltage of the light emitting diode. Additional complexity arises from the need for calculating uptime for multiple light emitting diodes of different colours. Brightness levels may also be factored in.

Abstract: A method of manufacturing a portable computing device, involves the steps of (1) maintaining a table comprising stimulus/response data for possible hardware components that may be interfaced in the computing device; (2) performing one manufacturing step in the manufacture of the portable computing device by interfacing one of the possible hardware components with one other component of the computing device; and (3) performing one other manufacturing step in the manufacture by: (i) applying a stimulus to the interfaced hardware component, and reading a response from the interfaced hardware component in response to the applied stimulus; (ii) identifying the interfaced hardware component from a correlation of the response with the stimulus/response data; and (iii) saving the identification as configuration data in the computing device.
