Title: Method and system for improving network resource utilization in a cellular communication system
Inventor: OSTRUP PETER
IPC: H04W28/18
Filed: 1999-07-13
Abstract: A hierarchically structured cellular network is disclosed. When an active mobile station requests a service that requires the use of a network resource not available in the cell handling the ongoing call (or, alternatively, during call set up), the network checks for cells on the higher levels to determine if the required resource is available. If the resource is available in a higher level cell, the call is handed over to that cell and the resource is allocated to the call. The call can be maintained in the higher level cell until the resource is no longer needed, or a "better" cell capable of providing the required resource is found.

Patent CA-2347253-A1 (CA)
Title: Method and apparatus for determining optical distance
Inventor: MELVILLE CHARLES D
IPC: G02B7/28
Filed: 1999-11-02
Abstract: Apparent distance of a pixel within an optical field of view F is determined. Incoming light is scanned along a raster pattern to direct light for a select pixel onto a light distance detector (36). The distance is sampled for each pixel or for a group of pixels. The light distance detector includes a concentric set of rings sensors (42-50). The larger the spot of light corresponding to the pixel, the more rings are impinged.    The diameter of the spot is proportional to the distance at which the light originated (e.g., light source or object from which light was reflected).      Alternatively, a variable focus lens (VFL) 62/70/80 adjusts focal length for a given pixel to achieve a standard spot size. The distance at which the light originated correlates to the focal length of the VFL.

Title: Methods and apparatus for nearly lossless-concatenated block transform coding
Inventor: FARYAR ALIREZA FARID
IPC: H04N7/30
Filed: 2001-05-23
Abstract: Methods and apparatus for performing near lossless-concatenated N-level constrained quantization Hadamard transform decoding are provided.  Accordingly, the present invention provides a transform-based coding technique, where the coding loss introduced during repeated encoding and decoding is reduced to a substantially insignificant level. This is accomplished by employing a constrained quantization and inverse quantization operation in each level of encoding/decoding in the decoder. In this manner, the concatenation error between each level of a decoder is reduced to a substantially minimum level and the quantization error introduced during quantization operations, i.e., originally at the encoder and in each level of the decoder, is substantially reduced.  Thus, the decoded bit stream that is output at the N-th level of the decoder is substantially the same as the original bit stream provided to the input of the encoder.

Patent CA-2356605-A1 (CA)
Inventor: YEKTA AHMAD
IPC: G01N21/64
Filed: 2001-08-30
Abstract: Process and formulation are described allowing fabrication of absorbance and fluorescence standards in cuvettes and micro-well plate, and other desirable containers, with particular application to drug discovery and high throughput screening of bioactive systems. The material medium is capable of incorporating a large number of dyes, individually or in combination, and can closely mimic real aqueous assays in optical properties such as the dye spectra, transparency, refractive index, and shapes of meniscus. The medium is compatible with addition of formulation components for control of foaming, vapor pressure, freezing point, dye bleaching, and molecular rotational correlation times. The process starts with the dispensing of a fluid dye-containing liquid into the vessel of choice, and its subsequent viscosification by chemical or physical means into a viscous gel. After further processing for stability, the container can be sealed with appropriate means. The standards are useful for calibration of spectrophotometric or fluorometric plate readers and imagers for correction of systematic spatial errors, for calibration of absolute intensities, and their replicates may be used to allow cross comparison of different instruments. Specialized standards can be used to check instrument performance in specialized assays relying on fluorescence resonance energy transfer (FRET), time-resolved fluorescence (TRF) and fluorescence polarization (FP).

Title: Foreign matter entanglement-preventing device in working engine
Inventor: ITO KEITA
IPC: F01P5/04
Filed: 2001-09-12
Abstract: In a working engine including a bearing mounted on an outer wall of a crankcase for carrying a crankshaft, an oil seal mounted on the outer wall of a crankcase and disposed outside and adjacent the bearing, and a cooling fan which is attached to an outer end of the crankshaft adjacent the oil seal with its blades turned toward the crankcase and which has blades protruding toward the crankcase, a cylindrical protective tube is formed on an outer sidewall of the crankcase to cover ends of bosses of the cooling fan, and a foreign matter-beating piece is formed on the cooling fan 16 in proximity to an outer peripheral surface of the protective tube.   Thus, even if a long foreign matter drawn in by the cooling fan such as a weed and the like has been entangled around the crankshaft, it can be beaten and loosened, or cut by the foreign matter-beating piece rotated along with the cooling fan. Therefore, it is possible to prevent the entanglement around the foreign matter around the crankshaft, thereby avoiding damage to the oil seal as a result of the entanglement.
