Abstract: An access-control system comprises using an access management server, a lock, and multiple instances of time-based codes. A time-based code may be input to a lock by physical presses on a keypad; radio communication (Bluetooth, RFID, NFC, WiFi); a sound or audio signal; touch or vibration pattern; light pattern of intensity or contrast); and/or a sequence/pattern of temperature changes.

Abstract: A method and system for employing a technology architecture for solving real world problems.

Abstract: An access-control system comprises using an access management server, a lock, and time-based codes. When a time-based code from the access management server does not match the time-based code computed by the lock, the lock may check temporally proximate time-based codes. Upon a determination that a temporally proximate time-based code matches, the lock may adjust its clock to re-sync with the access management server clock. Additionally, the lock may implement “soft matching” by determining that an input code is a match if it matches either a current or a proximate time-based code. Additionally, the access management server and lock may implement multiple parallel time-based code instances to facilitate additional functionality.

Abstract: A method for glare reduction may be implemented by a graphical code reader. The method may include illuminating a target area using a plurality of light sources. The method may also include capturing images of the target area using at least one image sensor. The method may also include determining that glare is present in at least one captured image. The method may also include determining glare information that indicates which of the light sources are responsible for the glare. The method may further include taking corrective action to reduce the glare in subsequent images based on the glare information that is determined.

Abstract: A graphical code reader may include means for capturing an image frame in accordance with a rolling shutter technique, and means for changing illumination while the image frame is being captured in order to perform glare correction. The graphical code reader may also include means for detecting characteristics of glare in a previously captured image frame.

Abstract: An imaging engine includes a multi-functional structure. This structure functions as an optics barrel. In other words, at least one lens is positioned within the structure. In addition, the structure functions as an attachment/mounting apparatus for an image sensor board, an illumination board, and possibly an illumination/targeting lens structure as well. The structure may also provide a mechanism for attaching/mounting the imaging engine to another structure, such as the housing of a graphical code reader.

Abstract: A graphical code reader that provides sequenced illumination for glare reduction may include a plurality of light sources that illuminate a target area. The graphical code reader may also include at least one image sensor that captures an image of the target area using a rolling shutter technique. The graphical code reader may also include an illumination controller that sequences illumination of the light sources so that the light sources that are providing the normal component of the illumination to an active portion of the target area are turned off, and so that the light sources that are not providing the normal component of the illumination to the active portion of the target area are turned on.

Abstract: A boat lift with a rotatable head attached to a bracket securable with respect to environmental structure such as a pier which to be capable of lifting a watercraft from the water and while rotating thereof to a position above an adjacent area such a dock area. The lift includes a rotating head assembly having a mounting fin extendable into the interior of a vertically reciprocating mast. A watercraft supporting cradle is secured to the mast to be movable therewith and includes vessel support members for facilitating retaining of a watercraft thereupon. Vertical movement between the mounting fin and the reciprocating mast is facilitated by sliding wear pads positioned therebetween.

Abstract: An imaging engine in accordance with the present disclosure includes a first image sensor section, a second image sensor section, an optics barrel, a first lens carriage that includes at least one lens, and a second lens carriage that includes at least one lens. The first lens carriage is positioned within the optics barrel so that there is a first optical path through the lens(es) in the first lens carriage to the first image sensor section. Similarly, the second lens carriage is positioned within the optics barrel so that there is a second optical path through the lens(es) in the second lens carriage to the second image sensor section. Advantageously, the position of the first lens carriage within the optics barrel and the position of the second lens carriage within the optics barrel are both independently adjustable.
