Patent CA-2192028-A1 (CA)
Inventor: HART WILLIAM T
IPC: A61M16/04
Filed: 1996-12-04
Abstract: An appliance is provided for installation within the mouth of an individual to prevent obstruction of the natural airway of the individual and to enhance natural ventilation during sleep. The appliance is hollow and is custom-molded to the oral cavity for biasing tissues surrounding the user's natural airway to keep the airway open. An external positive air supply is also provided which connects to a tube extending from the appliance and forces air through the hollow appliance to a rear opening of the appliance in the user's retroglossal area. A sensor provides control information to the positive air supply by sensing relative pressure in the user's oral cavity. The natural breathing cycle is thus enhanced but not controlled by the appliance.

Title: Automatic toaster and a control therefor
Inventor: SUTTON TIMOTHY B
IPC: H05B1/02
Filed: 1997-01-06
Abstract: An automatic countertop toaster and its control that divides the toasting cycle into three thermodynamic phases related to a change in the physical characteristics of the toaster and the item being toasted. The time of each of the three phases is adjusted according to the user inputs and current conditions to obtain the proper toasting time. The invention disclosed uses a microcomputer to interface with the user and control the toaster. The measured or estimated time since the last toasting cycle and the temperature inside the toaster are used by the microcomputer in table lookups to set the times for the three thermodynamic phases of the toasting cycle. Two of the phases are further modified by the toasting mode (normal, frozen, bagel, frozen bagel, reheat) and the toast darkness setting selected by the user. The sum of the three phases after modification is the total toasting time.

Title: Method and apparatus for synchronizing communications in a satellite based telecommunications system
Inventor: STEPHENS SCOTT A
IPC: H04L7/08
Filed: 1997-04-15
Abstract: A  method  and  apparatus  are  provided  for  maintaining synchronous return and forward communications links between user terminals and earth stations communicating via a common satellite in a satellite based telecommunications system.  Each user terminal maintains a closed synchronization loop with its associated earth station based on timing and frequency error offset signals received by the user terminals.  The user terminals update their internal timing and frequency generators based on the received error offset signals.  In an earth station sharing embodiment, one of the earth stations  is  designated  as  a  master  earth  station while  the remaining stations are designated as slave earth stations with respect to a common satellite.  The slave earth stations monitor a return link between at least one user terminal and the master earth station.  The slave earth stations update their internal reference timing  and  frequency  signal  generators,  in  order  to  remain synchronous  with the  return  link  between the monitored user terminal and the master earth station.  The slave earth stations maintained synchronous forward links by requesting synchronization update  information  from  the  monitored  user  terminal.    Upon receiving a request,  the monitored user terminal calculates a difference in timing and frequency between frames received from the requesting slave and associated master earth stations.  The user terminal transmits the difference in timing and frequency along its return link.   The slave earth station updates its forward link timing  and  frequency  reference  signal  generators  to  remain synchronous with the master earth station.

Title: Chemical timer for a visual test strip
Inventor: YU YEUNG S
IPC: C12Q1/00
Filed: 1997-08-29
Abstract: A chemical timer for a direct-reading reagent test strip changes color a predetermined time after a biological fluid is applied to the strip. The strip measures the concentration of an analyte in the fluid. The timer is a dry coating of an indicator, an enzyme-containing reagent that when hydrated can react with glucose to change the color of the indicator, an inhibitor to inhibit the change in color of the indicator, glucose, and optionally, an aldose that does not react with the enzyme in the reagent. Preferably, the reagent and glucose are present in excess in the coating, and the time it takes for the timer color to change can be controlled by the inhibitor concentration. The aldose provides timer stability, probably by interfering with glycosylation by the glucose in the dry state.

Title: Method for identification of mutations using ligation of multiple oligonucleotide probes
Inventor: YAGER THOMAS D
IPC: C12Q1/68
Filed: 1996-08-28
Abstract: A ligase-based assay which relies only upon knowledge of the wild-type sequence of a gene or gene fragment is used to detect all types of mutations, i.e., point mutations, insertions and deletions. The assay makes use of a set of oligonucleotide probes, which may be packaged in kit form, which hybridize in series along the length of the gene. The ligation of the probes together form a ligation product, the size of which is evaluated. When the gene or gene fragment being analyzed corresponds to the normal sequence and thus perfectly matches the probes, all of the probes in the set are ligated together, and the ligation product has a certain resulting size. When a mutation appears in the gene, the hybridization of the probe overlapping the mutation is impaired, with the result that some or all of the ligation product is of smaller size.  By evaluating the size of the ligation product, both the existence of a mutation and its approximate position can be identified.
