Abstract: Methods and systems of utilizing a ring magnet for magnetic sensing applications thereof are disclosed. A magnetoresistive sensor device can be provided which is associated with a ring magnet configured as a sensing target. The magnetoresistive sensor device is insensitive to magnetic pole polarities. The ring magnet is generally magnetized to include a plurality of magnetic poles, such that at least one pole thereof is larger than at least one other pole thereof. An output signal can then be produced from the magnetoresistive sensor device via a digital circuit thereof. The output signal is independent of a rotation of the sensing target. The sensor itself is rotationally insensitive provided that the ring magnet is symmetrically magnetized.

Abstract: Given a system which detects simple events, one can define a complex event by constructing a list of sub-events. In order to recognize a complex event, the system keeps a record of the sub-events that have occurred thus far and the objects involved in these sub-events. Whenever the first sub-event in a complex event's sequence is recognized, an activation for that complex event is created. The activation contains an indication of the identity of the object involved in the event. The activation also includes an index initialized to one. If a newly detected event matches the next sub-event in any of the currently open complex events, the index for that complex event is incremented. If the index reaches the total number of sub-events in that complex event, the complete complex event is recognized. Thus any desired alarm is generated.

Abstract: This invention employs probabilistic templates, or p-templates, which probabilistically encode the rough position and extent of the tracked object's image. The p-templates track objects in the scene, one p-template per object. They can be used to incorporate three-dimensional knowledge about the scene, and to reason about occlusion between the objects tracked by the p-templates. This invention requires video capture and digitization hardware, image processing hardware such as a digital signal processor, and a method for estimating the image size of a person standing at a given location in the image.

Abstract: This application describes the Interactive PP Assembly Language Editor (IPPALE), a software tool intended to help programmers write parallel PP instructions quickly and effectively. IPPALE consists of an editor that (on command from the user) extracts the current assembly language instruction, assembles it, and displays a graphical representation of how the instruction uses the resources of the processor. This allows the programmer to see immediately whether the instruction is legal, and also whether there are idle resources that could potentially still be used. The result is that programmers can experiment with a whole set of parallel instructions without ever invoking the PP assembler. We expect this to lead to faster learning, reduced programmer frustration, and improved overall productivity.

Abstract: A rotary cutter having a plurality of flights each having a tool holder receiving pocket extending radially inwardly from an outer surface of the flight. Each receiving pocket has a mounting socket at the innermost portion of the pocket which securely positions a tool holder, the tool holder being retained in the socket by a fastener.

Abstract: The present invention contemplates a method and apparatus for load-shedding duty cycling which overrides the normal thermostat control in a space conditioning system, upon receipt of an external signal as from the power company, in a manner such that the consumed power does not rise above the level that persisted just prior to the initialization signal. The present invention monitors the thermostat-controlled cycling pattern of a space conditioning system such as an air conditioner. Normally, the last thermostat-controlled cycle is then caused to become the reference or control cycle for the load shedding interval. That is, the ON portion of the reference cycle is caused to become the maximum allowable ON interval and the OFF portion of the reference cycle is caused to become the minimum OFF interval for the entire load shedding interval.The device may be started by a single radio command or other means. The release from load control may be automatically timed or based on other signals.
