A system and method are presented for using a two-dimensional (2D) LiDAR for three dimensional (3D) laser mapping. The 2D-LiDAR is mounted in a chassis. The method laser ranges a planar slice of the environment. Simultaneous with laser ranging the planar slice, the 2D LiDAR chassis is rotated about an axis to create a 3D laser mapping of at least a portion of the environment. More explicitly, the 2D LiDAR may include a laser ranger with a planar actuator, typically the combination of a laser and a rotating mirror. In addition, the 2D LiDAR chassis is mounted on a reciprocating actuator. Thus, the step of laser ranging the planar slice includes laser ranging the planar slice in response to the planar actuator. The step of rotating the 2D LiDAR chassis includes rotating the 2D LiDAR chassis around an axis parallel to the planar slice, in response to the reciprocating actuator.

System and method for three-dimensional mapping using two-dimensional LiDAR laser ranging

An improved printer controller system includes bitmap buffers for storing bitmaps as uncompressed data and a buffer manager for managing an allocation of the bitmap buffers to the bitmaps. The buffer manager is configured to recap one of the bitmap buffers according to a bitmap identifier associated with a requested bitmap. A method for managing buffer allocation in a printer apparatus includes allocating one or more buffers to a bitmap, assigning a bitmap identifier to the one or more buffers, and printing the stored bitmap. The method further includes releasing the one or more buffers, receiving a request including the bitmap identifier, and reallocating the one or more buffers to the stored bitmap.

Embodiments of the present invention comprise methods and systems for associating a hard-copy document with computer-readable information and for accessing that information.

Methods and systems for document reproduction management

The method and system which assure tight security over access to document data which is being handled in a system during scanning, copying, printing and faxing modes of operation. Security takes place with (1) substantially complete blockage of outside-world (network, telephone line) access to such data during the handling time, (2) prevention of any data writing to a hard-drive memory device, and (3) job-completion destruction of any data temporarily stored in a random access memory, before there is any post-job restoration to outside-world connectivity.

Secure document-data-handling system and methodology

A system and method are provided for the expedited reprinting of documents at a printer. The method comprises: receiving an initial print job identified with a job identification (JID); rendering the print job into a bitmap; in response to rendering the bitmap, initially printing a document; saving the bitmap in memory; and, in a job table, creating a cross-reference between the JID and the saved bitmap. Subsequently, the method comprises: receiving a selected JID; accessing the job table; accessing a print engine-ready bitmap associated with the JID by using the job table to locate a bitmap cross-referenced to the received JID; reading the located bitmap from a printer memory; and, reprinting a document in response to the bitmap. An associated network server can be used for posting a job table with selectable JIDs on an HTML webpage. Alternately, the JID selection is received in a print driver communication.

System and method for expedited reprinting

Data is partitioned and processed along a bit plane that includes symbols holding a particular place in the ordered symbol sequences of digital information to achieve efficient compression and reduce processing complexity.

System for improving storage efficiency of digital files

A speaker system having intelligence for communication with the amplifier. The speaker system contains a communications module that transmits information across the connection between the speaker system and the amplifier with regard to the speaker characteristics. The communications module may be powered by a rectifier that derives power from a high frequency carrier signal passed to it by a high-pass filter. The method of operating the speaker generates a carrier signal and powers the communications module using the carrier signal. The communications module transmits information to the amplifier so long as the carrier signal is present and shuts down when the carrier signal is no longer present. An optional step includes allowing communication to the speaker system from the amplifier.
