Title: Joint brace hinges
Inventor: BASTYR CHARLES
IPC: A61F5/01
Filed: 1998-10-19
Abstract: Hinges (12) for orthopedic and rehabilitation braces allow intuitive, convenient and positive control and adjustment of the limits to which the braces (10) may extend or flex.      Such hinges (12) also allow convenient locking of such braces (10). A flexion switch (24) and an extension switch (26) allow convenient repositioning of stops (56) or limits which limit flexion and extension of the brace (10). Such switches (24, 26) may be repositioned, however, only with repositioning pressure for moving the switch (24, 26) to a new position combined with safety pressure for unlocking the switch (24, 26). A brace locking switch may also be included. Such hinges (12) promote more effective post-operative and rehabilitation results because they, among other things, allow users easily to change the flexion, extension and fixation limitations of their braces (10) conveniently and in real time such as during post-operative and physical therapy sessions and workouts.
Patent CA-2308822-A1 (CA)
Title: Process for anticipation and tracking of eye movement
Inventor: SKOLMOSKI PHILIP
IPC: G09B9/30
Filed: 2000-05-15
Abstract: A method for anticipation and tracking eye movement for head tracked projectors which divides a projection surface into spherical triangles and uses interpolating calibration values stored at each vertex of the triangle. A  calibration map is used that contains information about the relationship between the user's head orientation and where they are looking with their eyes at each calibration point. The projection surface is divided into spherical triangles which are searched to find the triangle which contain the user's interpolated view point by performing a dot product test between the interpolated view point and the unit normal vectors inside the three planes that make up the sides of the spherical triangle extended back to the eye point. When a dot product test fails for any side of the triangle the pointer is followed to the adjacent triangle where the test starts over. When the triangle is found that has the interpolated view point inside it, the selected triangle is divided into three sub-triangles. Then the area of the sub-triangles inside the selected triangle is computed. The areas of the sub-triangles are then used to find ratios of the sub-triangles' areas versus the selected spherical triangle area for weighting the calibration points stored with each vertex. Then the weighted calibrations are added to the values for the interpolated view point. This creates a calibrated view point where the head tracked projector is then pointed and the computer generated simulated image is projected.

Title: Device for folding leading end of net-type bale wrapping material to enhance its full-width conveyance into the baling chamber
Inventor: ANSTEY HENRY DENNIS
IPC: A01F15/12
Filed: 2000-06-16
Abstract: A large round baler is equipped with a net wrap feeding mechanism mounted to the rear and bottom of the bale discharge gate. The feeding mechanism includes upper and lower feed rolls, with the lower roll being located closer to the discharge gate than the lower roll and, the pair of rolls thus being arranged to deliver wrapping material against an upright run of bale forming belts, the latter acting to carry the net to a pinch point formed between the belts, where they pass around a lower rear belt support roll, and a guide pan of a net material guide assembly that extends beneath and adjacent a lower run of the belts. A net wrap material cut-off device includes a fixed knife blade located forwardly of and extending parallel to the lower feed roll. The cut-off device further includes a pair of transversely spaced cut-off arms between which extend and to which are fixed an anvil. The arms are mounted for pivoting between a raised standby position, wherein the anvil is located adjacent the upper feed roll and a lowered cut-off position, wherein the anvil is engaged with the knife blade. A row of bristles is located between the lower feed roll and the knife blade at a position where it acts to strip the lower roll of net material having a tendency to wrap about the lower roll and to entangle the net material as the latter is brought against the bristles during severing of the net material tensioned between the feed rolls and the pinch point after a bale has been wrapped. The entangled net material results in the leading end of the net material becoming folded back on itself at the beginning of the next wrapping cycle, such doubling together with the operation of spreader rolls acting to deliver the net material to the baling chamber at its full width.

Title: Modulation method for transmitter
Inventor: LI XIAODONG
IPC: H04W84/02
Filed: 2000-07-12
Abstract: In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known a priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

Inventor: PETERSEN LARS-GORAN
IPC: H04L12/56
Filed: 1998-12-08
Abstract: A communications network has ATM cells with AAL2 protocol packets carried on a first interface between two nodes of the network. Using the AAL2 protocol packets, many user channels are multiplexed onto one ATM VC between the two nodes. In one of the two nodes designated as a control node, user channels are terminated by mapping AAL2 packets of the user channels into modified ATM cells having an AAL protocol different than AAL2. The AAL protocol utilized for the modified ATM cells, termed AAL2 prime, requires that AAL2 packets carried in the ATM cell payload be whole packets and that the ATM payload not have an AAL2-type start field. Preferably, in the AAL2 prime protocol only one whole AAL2 packet is carried per ATM cell payload. Termination of the AAL2 user channels at the control node preferably occurs at a pooled and centralized resource termed a cell handling unit. The provision of the cell handling unit and the AAL2 prime protocol advantageously allows standard ATM equipment, e.g., an ATM switch, to be employed. A mobile telecommunications network is provided as an example illustrated embodiment.
Patent CA-2314918-A1 (CA)
Inventor: GANAN CALVO ALFONSO
IPC: G01N21/01
Filed: 1998-12-16
Abstract: Atomized particles within a desired size range (e.g., 1 micron to about 5 microns) are produced from two immiscible fluids, a first fluid source containing the formulation to be atomized, and a second fluid source which is contained in a pressure chamber surrounding at least the area where the first liquid is to be provided. Upon presentation of the first fluid source to the second, the second fluid is forced out of an opening positioned in front of the flow path of the formulation. The first and second fluids interact dynamically to form a stable capillary microjet, which in turn results in the formation of a focusing funnel at the opening. Formulation passing through this a focusing funnel will atomize upon exiting the opening of the pressurized chamber without physically contacting the perimeter of the opening.
