Title: Purification of oligomers
Inventor: SPROAT BRIAN S
IPC: C07F7/18
Filed: 1998-06-25
Abstract: Compositions and methods are disclosed which facilitate purification of oligomers and other compounds. The disclosed compositions are silyl compositions that can be directly coupled, or coupled through a linking group, to a compound of interest, preferably to an oligomer at the end of oligomer synthesis. The silicon atom includes between one and three sidechains that function as capture tags. In one embodiment, the capture tags are lipophilic, which allows a derivatized oligomer to be separated from failure sequences by reverse phase chromatography. In another embodiment, the capture tags are compounds with a known affinity for other compounds, which other compounds are preferably associated with a solid support to allow chromatographic separation. Examples include haptens, antibodies, and ligands. Biotin, which can bind to or interact with a streptavidin-bound solid support, is a preferred capture tag of this type.

Title: Virtual address access to tiled surfaces
Inventor: SWANSON ROGER W
IPC: G06F12/02
Filed: 1998-06-18
Abstract: A data accessing system (160) provides access data to video display stored in one or more frame buffers (45) via a virtual frame buffer implemented as phantom port (201). The virtual frame buffer facilitates remapping between pixel coordinate space and memory address space for both tiled and linear addressing schemes. Generation of virtual linear and virtual tiled addresses is obtained through one or more of shifting, replacing, and concatenating operations. These operations can be implemented to perform very fast in comparison to the multiplication, addition, division, and modulo operations used in convential display processors, video controllers and central processing units (80). In some embodiments the virtual addresses are converted to addresses in a frame buffer for accessing the frame buffer. Alternate embodiments use a frame buffer adapted to respond directly to generated virtual addresses. The present invention can thus generate addresses for accessing data in a frame buffer and efficiently use data storage capacity in the frame buffer.

Patent CA-2302285-A1 (CA)
Title: Vacuum drums for printing, and duplex printers
Inventor: TEMPLE STEPHEN
IPC: B41J13/22
Filed: 1998-09-04
Abstract: A vacuum drum assembly for a printing machine comprises a drum having an array of passageways (40) distributed along its length and around its periphery to permit air to flow from outside the drum to inside the drum in response to reduced air pressure inside the drum, and an array of valve members (52), each valve member being movable between a closed position in which that valve member restricts at least one of the passageways and an open position in which the restriction of that passageway or those passageways is reduced. The arrangement is such that, when a partial area of the drum is wrapped with a sheet of material, at least some of the valves for the passageways adjacent the edges of that area are open, and the valves for the passageways which are not covered by the sheet and are not adjacent the edges of that area are closed. The open area of the drum is regulated such that it is small in regions where there is no paper. Accordingly, the open area of the drum is adapted to the shape and size of the paper and the position of the paper on the drum, whilst minimizing the required suction flow. A duplex printing machine comprises two such vacuum drum assemblies with their drums parallel. The air pressure inside the drums is reduced and the drums are counter-rotated. Material to be printed on is fed to the first drum so that the material can be held on the first drum by vacuum and rotated therewith, and a first print head prints on one side of the material. The material is then released from the first drum in a direction towards the second drum so that the material can be held on the second drum by vacuum and rotated therewith. A second print head then prints on the material on the second drum. The material is then released from the second drum.

Title: Method and apparatus for reducing the computational complexity and relaxing the critical path of reduced state sequence estimation (rsse) techniques
Inventor: VISWANATHAN HARISH
IPC: H03M13/41
Filed: 2000-05-29
Abstract: A method and apparatus are disclosed for reducing the complexity of reduced state sequence estimation (RSSE) techniques for a given number of states while also reducing the critical path problem. The signal energy of a pulse that has gone through a minimum-phase channel is concentrated in the initial taps. A  communications channel is represented using a discrete time model, where the channel impulse response has a memory length, L, denoted by {.function.'k}~=o, where .function.k is the coefficient for channel tap k. Taps one through U are referred to as the initial taps, and taps U+1 through L are referred to as the tail taps, where U is a prescribed number. The less significant tail taps are processed with a lower complexity cancellation algorithm, such as a decision-feedback equalizer (DFE) technique, that cancels the tail taps using tentative decisions. Thereafter, only the more significant initial taps are processed with a reduced state sequence estimation (RSSE) technique. The DFE technique initially removes the intersymbol interference associated with the tail taps, then the RSSE  technique (or M-algorithm (MA)) is applied only to the more important tail taps. Taps one through U are processed using the RSSE technique and taps U+1 through L are processed with the lower complexity decision-feedback equalizer (DFE). A receiver is disclosed that includes a tentative decision/tail processing circuit, such as a decision-feedback equalizer (DFE) technique, for processing the less significant tail taps and an RSSE  circuit for processing the initial taps.

Title: Flame and smoke detector
Inventor: SIVATHANU YUDAYA
IPC: G08B17/12
Filed: 1999-01-19
Abstract: A fire and smoke detector (4) utilizes a statistical analysis of the near infrared radiation incident on it. The spectral radiation intensities incident on the fire detector are continuously measured at two near-infrared wavelengths, and a time series of apparent source temperatures is obtained from these measurements. The power spectral density (PSD) and the probability density function (PDF) of the apparent source temperatures are sufficient to determine the presence of a fire in the vicinity of the detector (4). The detector (4) can indicate the presence of a fire in an adjoining room from the radiation which is incident on it due to reflections from common building materials. The present invention relates to fire and/or smoke detection methodology and associated apparatus. The detector (4) utilizes fiber optic as a viewing and absorption/scattering detection means.
