Title: Variable focus lens by small changes of the equatorial lens diameter
Inventor: SCHACHAR RONALD A
IPC: G03F7/20
Filed: 1996-05-10
Granted: 2008-01-08
Abstract: A variable focus lens is constructed by mak-ing small changes in the equatorial diameter of an elastically deformable lens (102, 202, 302, 402, 502). The lens (102, 202, 302, 402, 502) may be deformed by radial tension exerted in a plane gen-erally perpendicular to the optical axis. The radial tension may be exerted by radially acting mechani-cal apparatus (106) or by means of rings (206, 306, 406, 506) embedded or attached at the equator of the lens, whose diameter can be altered by heating, or by imposition of electrical or magnetic fields.

Title: Light reflectant surface for luminaires
Inventor: MINOR RAYMOND B
IPC: F21V7/22
Filed: 1997-04-08
Granted: 2001-06-05
Abstract: The present invention relates to surfaces used to reflect light, and particularly to highly light reflectant surfaces that provide even diffusion of light for the purpose of maximizing light efficiency and/or uniformity in a luminaire. By employing an expanded polytetrafluoroethylene (PTFE) comprising a microstructure of polymeric nodes and fibrils, the material of the present invention demonstrates exceptional diffuse reflectivity across a wide spectrum of visible light. Additionally, the material of the present invention provides many properties that have been previously unavailable in highly diffuse reflective material, including a high degree of malleability, moldability and flexibility, and effective reflectivity even at relatively thin cross sections.
Patent CA-2237408-C (CA)

IPC: G01V1/37

Granted: 2001-01-09
Abstract: A method of separating the effects of the earth response on vibratory energy from individual ones of multiple vibrators (Va-Vd) to geophones (G1-G5), in generating a seismic survey, is disclosed. According to the disclosed method, measurements of the actual vibrations generated at the source are made, in addition to the geophone measurements of the refracted and reflected vibrations, both over a number of frequency sweeps. The source (Va-Vd) and geophone (G1-G5) vibrations are first transformed into frequency domain representations, by way of Discrete Fourier Transforms. An inverse matrix of the recorded frequency-domain source vibrations is then generated for each frequency. When the number of sweeps equals the number of vibrators (Va-Vd), the inverse matrix is merely the multiplicative inverse of the source measurements; if the number of sweeps exceeds the number of vibrators (Va-Vd), the inverse matrix is the generalized inverse of the original matrix. The inverse matrix for the frequency is applied to the recorded geophone vibrations at that frequency, to derive the transfer function (ha-hd), corresponding to the earth response, for each vibrator-geophone path in the survey. A weighing factor may be used to discount the effects of poorly behaved sweeps, and may be based on the ratio of the maximum and minimum eigenvalues for the inverse matrix. Using the derived transfer functions (ha-hd), an earth reflectivity function may be derived for each vibrator-geophone path by applying a minimum phase filter to the separated vibrator-geophone transfer function over frequency.

Abstract: In a skills-based ACD, an available agent is reserved and assigned to handle calls needing a "rare" skill of the agent and is prevented from handling calls needing a "common" skill of the agent even if calls needing the common skill are waiting to be handled, if not reserving the agent for the calls needing the rare skill would deprive those calls of the last available agent, even if no calls needing the rare skill are available for handling. The agent is reserved only if target performance criteria, such as average speed of answer, for handling the calls needing the common skill are being met. In case of more than one agent being available to handle calls that need the rare skills, one of these agents is selected and reserved and the other agents are freed to serve calls needing "common" skills.

Abstract: A method for the in-situ recovery of viscous petroleum hydrocarbons from an underground formation includes the following. A production well is provided within the formation. Solvents are maintained in the formation abov e the production well which are capable of dissolving in and diluting the hydrocarbons to promote drainage of the solvent-diluted hydrocarbon toward the production well. A vapour chamber is created above the production well i n the hydrocarbon-depleted formations resulting from said drainage. A hot zone is maintained adjacent the production well to vaporize the solvents containe d in the downwardly draining hydrocarbons prior to their entry into the productio n well. These vaporized solvents move upwardly through the vapour chamber in a continuing manner to again contact said hydrocarbons in the formations at the boundaries of the vapour chamber to promote the continued dilution and drainage of the hydrocarbons toward said production well whereby a substantial portion of the solvents are recycled in a closed-loop fashion. Special concentric tubing closed loop heating systems provide the desired h ot zones to enhance the operation of the process as required.
