Title: Therapeutic behavior modification program, compliance monitoring and feedback system
Inventor: DOUGLAS PETER
IPC: G06F19/00
Filed: 1998-07-10
Abstract: A therapeutic behavior modification program, compliance monitoring and feedback system includes a server based relational database, and one or more microprocessors electronically coupled to the server. The system enables development of a therapeutic behavior modification program having a series of milestones for an individual to achieve lifestyle changes necessary to maintain his or her health of recovering from ailments of medical procedures. The program may be modified (1012) by a physician or trained case advisor prior to implementation. The system monitors the individual's compliance (1050) with the program by prompting the individual to enter health-elated data (1030), correlating the individual's entered data with the milestones in the behavior modification program, and generating compliance data indicative of the individual's progress toward achievement of the program milestones. The entire system is designed around a community of support motif including a graphical electronic navigator operable by the individual to control the microprocessor for accessing different parts of the system.

Title: Method and apparatus for interfacing analog telephone apparatus to a digital, analog or hybrid telephone switching system
Inventor: STELMAN BRUCE W
IPC: H04M3/42
Filed: 1998-11-05
Abstract: An adaptive handset interface method and apparatus for interfacing a two-wire analog telephone instrument, such as a modem, fax modem, facsimile machine or teleconferencing device, to a digital, analog or hybrid telephone system, such as a private branch exchange (PBX). The interface device is suitable for use with a variety of PBXs produced by different manufacturers, despite differences in signalling characteristics between the PBX and an associated PBX-compatible telephone.  In a preferred embodiment, the invention does not require access to a handset port of the PBX-compatible telephone. The interface device is connected to the extension line along with a PBX-compatible telephone. An analog telephone instrument is then connected to the interface device. In order to communicate with the PBX using a communication protocol appropriate to the PBX, the interface device 'learns" the characteristics of the PBX. This is accomplished by: determining whether the telephone system is an analog or digital telephone system; and, if the telephone system is a digital telephone system, monitoring communications between the PBX and the PBX-compatible telephone. Then, the interface device is configured according to the appropriate protocol by retrieving a set of operational parameters from a plurality of such sets pre-stored in a memory device within the interface device. The learning technique allows the interface device to automatically adapt itself to variations in signalling characteristics between the PBX and PBX-compatible telephone sets among the different PBX manufacturers.

Title: Heat exchanger and method of making it
Inventor: WATANABE YOSHINORI
IPC: F28F3/04
Filed: 2000-05-24
Abstract: A heat exchanger is constructed by tubes (11), corrugated fins (14) and head pipes (12, 13), which are assembled together. Herein, the tube is constructed by bending a flat plate (20) whose surfaces are clad with brazing material to form a first wall (21) and a second wall (22), which are arranged opposite to each other with a prescribed interval of distance therebetween to provide a refrigerant passage (23). Before bending, a number of swelling portions (25) are formed to swell from an interior surface of the flat plate by press. By bending, the swelling portions are correspondingly paired in elevation between the first and second walls, so their top portions (25a) are brought into contact with each other to form columns (26) each having a prescribed sectional shape corresponding to an elliptical shape or an elongated circular shape each defined by a short length (d1) and a long length (d2). The columns are arranged to align long lengths thereof in a length direction (A) of the tube corresponding to a refrigerant flow direction such that obliquely adjacent columns, which are arranged adjacent to each other obliquely with respect to the length direction of the tube, are arranged at different locations and are partly overlapped with each other with long lengths thereof in view of a width direction (B) perpendicular to the length direction of the tube. The tubes, corrugated fins and head pipes are assembled together and are then placed into a heating furnace to heat for a prescribed time.

Title: Liquid crystal display with nonspecular reflectors
Inventor: YEOH COLIN T
IPC: G02F1/1335
Filed: 2000-08-11
Abstract: The present invention deals with liquid crystal displays where the incident light and reflected light going through the display are not specularly related. The incident light can be at a range of angles to the display while the reflected. light, i.e. the viewing direction is at or nearly normal to the display. For such nonspecular liquid crystal displays, the polarizer angles, the input/output directors of the liquid crystal cell, and the liquid crystal cell retardation have to be specially optimized to obtain the best viewing effects.  Conventional liquid crystal display modes do not work optimally in this nonspecular situation. We also disclose the new image-mode and shadow-mode nonspecular liquid crystal displays. Such displays have very bright background and are free from viewing glare common in most liquid crystal displays. The present invention applies to all twist angle, e.g. the 90° TN, the 120° and 150°      HTN, the 180°, 240° and 270° STN displays.

Filed: 1999-01-05
Abstract: The invention relates to a flatware set for spaghetti. When spaghetti is eaten the spaghetti threads are taken up onto the fork by turning the fork on its axis. In order to improve the spaghetti take-up, the fork (5) has the feature that the at least two teeth (8, 9) extend substantially helically round a central axis of the fork. The fork teeth (8, 9) then pick up the threads of spaghetti better. Despite a helical shape of the teeth (8, 9), it is nevertheless possible to eat conveniently with this fork (5), since this fork (5) is pulled out of the mouth in a helical movement.

Patent CA-2325970-A1 (CA)
Inventor: SCHMITZ DAVE
IPC: G01R11/00
Filed: 2000-11-14
Abstract: During operation of a mechanical press, it is useful to measure the amount of energy consumed in a typical press stroke.      Energy measurements assist a press operator in determining whether the motor and flywheel combination is sufficient for a particular application, and whether any press parts have become inefficient. The invention uses speed determinations of a selected rotating or moving press part along with known values for the inertia of the press part to determine the difference in total energy over a preselected interval. The calculations can then be compared to previous calculations and desirable values to determine press efficiency. Additionally, the meter can report further useful calculations such as press slowdown percentage, a function of the difference in the already-known speed determinations.
