Patent CA-2300859-A1 (CA)
Title: Faster two-step sealing of anodized aluminum surfaces
Inventor: JOHNSON PHILIP M
IPC: C25D11/18
Filed: 1998-08-19
Abstract: Anodized aluminum surfaces are advantageously sealed by an energy- and time-saving two step process, in which the first step is contact at not more than 75 ~C with a solution containing lithium and fluoride ions and, optionaly, surfactant. The second necessary step is treatment with hot water or steam, which may be completed in considerably less time than when only hot water or steam is used for sealing. Conventional smut inhibitors and/or neutral buffers as used in hot water for single step sealing may advantageously be included in the second step of this process. 100 - 1000 ppm concentrations of nickel and/or cobalt ions in the treatment liquid for the second treatment step, if environmentally tolerable, make it possible to complete this step in as little as 10 minutes at a temperature as low as 88 ~C.

Abstract: Apparatus and method for mass producing a unique dining experience for each individual diner within a group of patrons includes computers, applications software, models and databases. Through various alternative input mechanisms, each individual patron's preferences will be surveyed, and the results of the surveys are stored within the database. Staff and management of an establishment are also surveyed regarding various personal and facilities capabilities and assets. The preference surveys may be quite basic in nature, but with more detailed surveys a more elaborate model may be generated. Based upon the preference survey results, a dining event is developed that groups patrons according to areas of agreement among surveys, while simultaneously tailoring unique events or decor based upon the preference survey results that are not common among the patrons. The dining event is prepared for, including training of staff and management, and the dining event is then staged. During the event, an off site person will most preferably provide monitor and provide feedback to the staff and management, and subsequent to the event further evaluation will occur. Based upon the event results and evaluation, the database and model may be updated. Electronic devices may form a part of the apparatus, and in this case will most preferably be controlled by computerized components to perform appropriately according to the stored model of the event. As a result of the differences in preferences, skills and assets of all participants, no two dining events will be identical. However, each dining event is designed and prepared according to pre-established models to fulfill each of the needs and expectations of each individual patron while simultaneously capitalizing on the strengths and talents of a staff and facility.  Simultaneously, the managerial burden of maintaining a single atmosphere within an establishment is relieved, and patrons are offered unexpected, but consistently high-quality, dining experiences.

Patent CA-2324980-A1 (CA)
Title: Electronic lancing device
Inventor: BERNSTEIN GARY H
IPC: A61B5/15
Filed: 2000-11-01
Abstract: It has been discovered that the use of a substantially free-standing voice coil within a lancing device in coordination and combination with a stationary magnet and electronic circuit renders a much improved lancing device. The minimal weight of the free standing voice coil and the attractive forces of the magnet allow the battery-powered electronic circuit to maintain excellent control over the advancement and retraction of a lancet. When the electronic lancing device is initiated by a user, the voltage source within the electronic lancing device provides sufficient current through the voice coil such that the coil and lancet are repulsed from the magnet and propelled into the puncture site. The voltage source subsequently reverses the current through the voice coil to supply sufficient attractive current through the voice coil such that the dwell time of the lancet is minimized and the lancet is retracted from the puncture site and pulled toward the magnet within the housing of the electronic lancing device.
