Title: Decoding barcode using smart linear picklist
Inventor: WANG DAYOU
IPC: G06K7/14
Filed: 2015-04-20
Abstract: A method of decoding a barcode includes determining number of barcode candidates in the image captured and processing the image captured in accordance with the number of barcode candidates found. If the number of barcode candidates is one, the image captured is processed to decode the only one barcode candidate in the image captured. If the number of barcode candidates is larger than one, the image captured is processed to find a barcode candidate that overlays with an aiming location between a first location and a second location on a scan line and to decode the barcode candidate that is found that overlays with the aiming location.

Filed: 2017-03-17
Abstract: An amplifier circuit 100 includes a voltage regulator 102, with a capacitor 103 at its output, supplying an output voltage VS to an amplifier 104. The regulator is operable in a first voltage-control mode to maintain the output voltage at a nominal output voltage to provide the amplifier with a nominal voltage headroom.

In a further arrangement, the voltage regulator additionally operates in a second current control mode to avoid exceeding a defined current limit and, in response to an indication of a high amplitude part of the input signal that could result in current limiting, the controller increases the regulator output voltage and voltage headroom to allow for voltage droop over a plurality of switching cycles. The amplifier circuit is particularly suitable for devices using batteries, such as portable communication or audio devices.
