Abstract: A method and system is disclosed for enabling full-service communications between a full-service cable modem termination system (fsCMTS) and a plurality of full-service cable modems (fsCM's) for a conventional two-way hybrid fiber-coax (HFC) cable television network. Full-service communications include data, voice and video. Video includes broadcast quality MPEG-2 transport streams and Internet protocol media streams. A multi-channel full-service media-access-control (fsMAC) coordinates the access to the shared upstream and downstream channels. At lease two downstream channels and at least two upstream channels are provided. Several MAC management messages are defined to enable multi-channel full-service MAC domain to be defined and to enable packet-by-packet true seamless channel change. Using the novel techniques described in this invention, multiple upstream channels can be used in various ways to best optimize the use of the spectrum for accommodating various quality-of-service needs of different type of services.

Abstract: A traveling slip assembly of a snubbing unit is supported directly through mechanical fastening of two or more hydraulic actuators to one or more load members extending from a tubular snubbing structure for transfer of snubbing loads to a wellhead. A stationary slip assembly is supported by the snubbing structure and is substantially independent from the hydraulic actuators. This arrangement ensures proper alignment of the traveling and stationary slip assemblies and the tubular snubbing structure enabling ease of assembly, precise alignment and a lighter overall structure. Preferably, the load members are part of a load plate which is mechanically fastened to an outer flange on the snubbing structure, and separate therefrom, thereby being isolated from the wellbore fluids and permitting the load plate's material properties to be selected without consideration of corrosion restrictions and thereby allowing a stronger and lighter load plate to be employed.

Abstract: Three-dimensional (3D) reconstruction of a cell (1) includes adjusting a current set of projection images (8, 9) according to a priori knowledge (24) to produce adjusted projection images (9), for example, based on probability masks and/or Bayesian analysis (16) of multiple similar objects in the same sample (30). A reconstruction algorithm processes the adjusted projection images to generate a 3D image (10). The 3D image is further adjusted according to the a priori knowledge (24) to generate an adjusted 3D image (11). Criteria for process completion are applied to determine whether the adjusted 3D image is adequate (12). Otherwise, a set of pseudo projections are computationally created at the same projection angles as the current set of projection images (8, 13) and then compared to the current set of projection images (8) to produce a set of new projections (14), wherein the new projections are input again to the reconstruction algorithm and the steps of the method are repeated until the adequacy criteria are met (15).

Abstract: The object is to provide a printing apparatus wherein the rotation of endless printing bands is limited in a manner that keeps excessive rotational force from acting on the endless printing bands 7 themselves, thereby avoiding wear, cracking and other damage, and wherein forcible rotation of the endless printing bands causes idle rotation of selector wheels 5 and puts only moderate load on the endless printing bands. Attention is directed to adoption of selector wheel 5 rotation restricting members of a movable type and to enabling the movable stop members 14 to move when excessive force acts on the selector wheels 5 or the endless printing bands 5. A stop bearing member 15 is provided to abut on elastic sections 14B of the movable stop members 14, and engagement between drive projections 7E and the elastic sections 14B with movement of the endless printing bands 7 enables movement of the movable stop members 14.
