Abstract: An optical assembly for an autofocus imaging system for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a front aperture along an optical axis and a front lens group along the optical axis that receives light from the object of interest. The position of the front lens group is adjustable to change a focal distance of the optical assembly. The optical assembly further includes an actuator physically coupled to the front lens group that adjusts the position of the front lens. A rear lens group is disposed along the optical axis to receive the light from the front lens group, and an imaging sensor is disposed at a back focal distance of the rear lens group, to detect the light.

Abstract: An optical assembly for an autofocus lens system for imaging an object appearing in an imaging field of view (FOV) is provided. The optical assembly includes a compensator lens assembly disposed along an optical axis, with the compensator lens assembly configured to receive light along the optical axis and to provide tuning of a flange focal length of the optical assembly. A variable focus assembly, including a variable focus optical element, is disposed along the optical axis to receive light from the compensator lens assembly. The variable focus optical element has a tunable focal plane. A fixed focus optical group is disposed along the optical axis to receive light from the variable focus assembly, the fixed focus optical group is configured to focus the light at the flange focal length of the optical assembly.

Abstract: A scan engine for capturing at least one image of an object appearing in an imaging field of view (FOV) is provided that includes an imaging system, illumination system, aiming system, and a first and second chassis. The imaging system includes a lens holder and at least one lens disposed within the lens holder and both a far imaging system and a near imaging system for capturing images across multiple fields of view at different distances. The illumination system and aiming system are physically positioned to provide illumination of a target in the near and/or far fields of view, and provide an aiming pattern to the near and/or far fields of view.

Abstract: A method for detecting and correcting firmware corruption in a system having a host communicatively coupled to an electronic apparatus, the electronic apparatus having a hardware unit communicatively coupled to a non-volatile memory, includes determining via the hardware unit whether firmware on the non-volatile memory is corrupted; if the firmware is determined to be corrupted, then: invoking a communication driver resident in the hardware unit to establish bi-directional communications between the host and the electronic apparatus; and initiating a firmware download from the host to update the firmware on the non-volatile memory to an uncorrupted state.

Abstract: The loudspeaker particularly comprises two-aperture radiator (1) containing paired in-phase counter-radiating apertures (4) and reproducing middle frequencies. Apertures (4) face each other, and their geometrical axis F is positioned vertically, while the distance between apertures (4) equals to at least the radius of aperture (4) but does not exceed the wavelength of the lowest frequency reproduced by paired apertures (4).
