Abstract: A method for making smoothies and granitas includes the utilization of a bottle having a replaceably removable sealing cap, a fill indicium thereon spaced from the top of the bottle, a flavor concentrate in the bottle of a quantity and concentration predetermined for producing a mixture of another predetermined flavor concentration when combined with a liquid introduced into the bottle to the fill indicium.  Such bottles with contained flavor concentrate are distributed to users who introduce a liquid into the bottle for combining with the flavor concentrate until the fill indicium is reached, and shaking the closed bottle until the concentrate is mixed with the liquid to produce a mixture of such other predetermined concentration. The mixture may be added to a blender, along with ice and perhaps further liquid, in predetermined proportions, in a blender for producing a smoothie or slush; or the mixture may be added to a granita machine for making a granita.

Patent CA-2276891-A1 (CA)
Inventor: WHITE IAN
IPC: B27N1/00
Filed: 1999-07-02
Abstract: A method is described for producing light colored composite panels by applying a buffer or weak acid system either in solution or in powder form prior to the hot press. The buffer or weak acid system, applied on the mat surfaces prior to hot pressing, reduces the pH of the environment on the mat surfaces and consequently reduces the degree of oxidation of the phenolic resin during hot pressing as well as retains the oxidized phenol formaldehyde polymers in their protonated forms after the hot press, thereby significantly reducing or eliminating the darkening of the finished composite panels.

Title: Dual mode ophthalmic laser ablation
Inventor: HOHLA KRISTIAN
IPC: A61F9/01
Filed: 1998-04-24
Abstract: A dual mode excimer laser eye surgery system is provided. The eye is first treated for primary corneal defects using a large, fixed spot size, and remaining irregularities are removed using a small fixed spot size. The large size allows for faster treatment, and the small size provided for more precision in the treatment of irregular topographies. The system is preferably implemented in a distributed topography environment. For example, a treatment pattern using a large, fixed spot size is provided to doctors based on visual acuity data, such as the degree of dioptric correction needed. The effect of this treatment is then overlaid on a computer against the patient's actual eye topography. The small fixed spot size is used to remove any remaining irregularities yielding a preferred treatment pattern. This combined treatment pattern is then distributed to an excimer laser eye surgery system that performs the large spot size ablation and then the small spot size ablation.

Title: Method of validation and host buffer allocation for unmapped fibre channel frames
Inventor: DUCKMAN DAVID
IPC: H04L49/901
Filed: 1999-03-24
Abstract: A method of validation and host buffer allocation for unmapped fibre channel frames. More particularly, the invention encompasses a method of validating unmapped frames, each including a header and a payload, including receiving a frame (500) as a current frame; determining if the current frame is a first frame in a sequence (502), and if so, saving the header and payload of the current frame in a buffer (504), and otherwise determining if the current frame is a next expected frame in the sequence (508), then saving the payload of the current frame in the buffer after the payload of the prior frame (512);  determining if the current frame is a last frame in the sequence (510), and if so, sending a message to a host indicating receipt of the complete sequence (518); if the current frame is not the next expected frame in the sequence, then saving the header and payload of the current frame in the buffer (520), and sending a message to the host indicating receipt of a partial sequence (522). The host CPU is interrupted when either a complete sequence is received, or a partial sequence is received, followed by a frame from a different sequence. The host CPU may then process the concatenated payload of the sequence. The invention is particularly useful for processing TCP/IP  frames in a Fibre Channel network.

Abstract: An automated method and system for identifying date-sensitive entries in a database wherein an obligation must be satisfied relative to the entry according to instructions provided by the beneficiary of the obligation. The method and system of the invention can be practiced from a location remote from the database and are particularly useful in a number of situations and particularly those wherein unticketed reservations are maintained in a storage medium for a time prior to issuance of a ticket to "firm up" the reservation to a ticketed status. The present system and methodology finds particular utility enforcing ticketing time limit rules on travel agency or other reservation and ticket issuers involved in the reserving and ticketing of airline bookings and the like and results in the reduction of no-shows and overbooking while increasing onboard load factors on sold-out flights in particular. The automated system of the invention is capable of operating essentially continually throughout seven days a week and twenty-four hours each day to constantly "firm" all or selected flights of a given carrier. Enforcement of ticket time limit rules can extend at the option of a user to booking class, market, point of sale and the like or any combination thereof.
Patent CA-2333062-A1 (CA)
Inventor: AL-ALI AMMAR
IPC: A61M16/00
Filed: 1999-05-27
Abstract: An improved pulse oximeter provides for simultaneous, noninvasive oxygen status and photoplethysmograph measurements at both single and multiple sites.  In particular, this multiple-site, multiple-parameter pulse oximeter, or "stereo pulse oximeter" (100) simultaneously measures both arterial (SPA02) and venous (SPV02) oxygen saturation at any specific site and generates a corresponding plethysmograph waveform. A corresponding computation of arterial minus venous oxygen saturation is particularly advantageous for oxygen therapy management. An active pulse-inducing mechanism having a scattering-limited drive generates a consistent pulsatile venous signal utilized for the venous blood measurements. The stereo pulse oximeter also measures arterial oxygen saturation and plethysmograph shape parameters across multiple sites. A  corresponding calculation of delta arterial saturation and comparison of plethysmograph shape parameters between multiple sites is particularly advantageous for the detection and management of persistant pulmonary hypertension in neonates (PPHN), a patent ductus arteriosis (PDA), and aortic coarctation.
