    摘要： A method and apparatus for maintaining a maximum sustained flash current over the whole length of a flash using a programmable current drive in a handheld portable device powered by a battery. The method involves measuring the battery voltage before and after a flash is initiated and calculating the equivalent series resistance (ESR) of the battery. The calculated ESR is then used to adjust the flash current. The process may be repeated to correct for errors in the flash current.

    摘要： A mobile wireless communications device is for use with a hearing aid including a hearing aid compatible (HAC) coil. The device may include a portable housing and a wireless receiver carried by the portable housing. The device may also include at least one image capture component and a positioning coil associated therewith and carried by the portable housing. A controller may also be carried by the portable housing for selectively operating the positioning coil for image capture, and for inductively coupling received signals from the wireless receiver to the HAC coil.

    摘要： 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.
