Abstract: Methods and a system for dynamically modifying charging settings for a battery assembly are described. A first usage value and a second usage value for the battery assembly are received. A usage difference value for the battery assembly is determined by comparing the first usage value to the second usage value. The usage difference value is compared to a plurality of battery usage ranges. Each battery usage range is associated with a bin count, a different voltage offset, and a different current offset. The bin count of one of the plurality of battery usage ranges is updated based on the comparison. The bin counts of the plurality of battery usage ranges are analyzed to determine a largest bin count and a respective battery usage range. The battery assembly is charged with a voltage offset and a current offset corresponding to the respective battery usage range with the largest bin count.

Abstract: Systems and methods for providing an improved lamp mode for an imaging device. The imaging device may include an image sensor; an illumination source; and a processing assembly communicatively coupled to the image sensor and the illumination source, and the processing assembly may be configured to: responsive to a scanning event trigger, cause the imaging device to enter a first illumination mode, wherein, in the first illumination mode, a first activation duration of the illumination source is synchronized with an image frame rate of the image sensor to capture image data at the image sensor for indicia decoding; and responsive to sensing an external signal at the imaging device, cause the imaging device to enter or exit a second illumination mode, wherein, in the second illumination mode, a second activation duration of the illumination source is greater than the first activation duration.

Abstract: At least some embodiments are directed to systems and methods to optimize relative signal delays in vision systems having illumination assemblies separate from a host. In an example embodiment there is a system that includes a host device having, an imaging assembly coupled to the host device and operable to capture image data, and an illumination assembly coupled to the host device and operable to provide illumination. The system is configured such that the host transmits, to the imaging assembly, a series of exposure signals causing the imaging assembly to capture a series of frames and transmits, to the illumination assembly, a series of illumination signals causing the illumination assembly to provide the illumination as a series of strobes. Thereafter the host evaluate each frame to identify a peak-brightness frame and from that, based on a corresponding illumination signal, determines an appropriate relative signal delay for future operations.

Abstract: A variety of barcode scanner assemblies for inductive charging include a reader, a stand, a first inductive coil having a first coil axis, and a second inductive coil having a second coil axis. For some assemblies, in the charging position, gravity and a cradle of the stand urge alignment of the first inductive coil and the second inductive coil along the first coil axis and the second coil axis and minimize a gap between the first coil axis and the second coil axis. For some assemblies, in the charging position, a torque is exerted upon the reader by gravity, the torque urging proximity between the first inductive coil and the second inductive coil and alignment features of the stand urge alignment of the first inductive coil and the second inductive coil along the first and second coil axes.

Abstract: A method and arrangement for wirelessly charging a barcode reader in a base station is disclosed. The barcode reader and base station each have an induction coil. The induction coil in the base station is electrically coupled to an electric power source, and generates an electromagnetic field. The induction coil in the barcode reader is electrically coupled to a power storage component. The barcode reader is configured to rest on the base station. When the barcode reader is resting on the base station, the induction coil in the barcode reader is exposed to the electromagnetic field, and a current is induced in the induction coil in the barcode reader. A positioning feature of the base station constrains movement of the barcode reader along a first plane, and permits rotation of the barcode reader about a vertical axis that is substantially normal to the first plane.

Abstract: Systems and methods for improving device locatability are disclosed herein. An example method includes determining a beacon mode capacity of a device battery, the beacon mode capacity corresponding to a device operating in a beacon mode while powered by the device battery. The example method further includes calculating a total battery power of the device battery and an aged total battery power of the device battery based on the total battery power and a state of health (SOH) of the device battery. The example method further includes determining a beacon state of charge (SOC) threshold for the device battery based on the beacon mode capacity and the aged total battery power, and causing the device to begin operating in the beacon mode when a remaining charge of the device battery is less than the beacon SOC threshold.

Abstract: Methods and apparatus for providing indications of shutdown states for handheld barcode scanners are disclosed herein. An example handheld barcode scanner includes a power source, a power source monitor, an indicator, and a processor disposed inside a housing. The power source monitor is configured to detect whether the power source has reached a pre-determined amount of discharge at which the internal power source is to be shut down to prevent damage. The processor configured to, when the internal power source has reached the pre-determined amount of discharge: configure the indicator to provide, while the internal power source is in the shutdown state, an indication that the internal power source is shutdown, and configure the internal power source into the shutdown state such that an image sensor, an indicia decoder, and the processor are de-energized.
