Title: Display techniques for three-dimensional virtual reality
Inventor: ENSOR JAMES ROBERT
IPC: G06T15/20
Filed: 1999-04-29
Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen occurs when a computer graphic object represented by computer graphics, e.g., in front of, to the side, above, or below the video screen, undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, because such an object would disappear from view by the viewer. This limitation is overcome by having by determining when a computer graphic object undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, and representing such an object as computer graphics in front of the screen to which at least one perspective transformation is applied, the perspective transformation being at least a function of the position at which the object is actually located.

Abstract: Procédé pour élever la concentration d'un facteur de croissance apparenté à l'insuline (IGF), qui consiste à convertir l'IGF contenu dans les organismes vivants en IGF libre présentant une activité IGF suffisante, et procédé pour élever la concentration du complexe IGF/IGFP (protéine fixatrice du facteur de croissance apparenté à l'insuline) dans les organismes vivants. L'invention concerne en outre une substance permettant d'élever les concentrations de ce facteur de croissance et du complexe associé, des médicaments contenant cette substance et un procédé pour cribler cette substance. L'effet IGF est ainsi obtenu par l'administration par voie externe non pas de l'IGF, mais de la substance capable d'accroître la concentration d'IGF libre dans les organismes vivants. Cette substance est utile comme agent de prévention et/ou de traitement dans les maladies pouvant être prévenues ou traitées par l'IGF, telles que le diabète, la sclérose latérale amyotrophique et l'ostéoporose.

IPC: H04Q3/00
Filed: 1999-07-23
Abstract: A method and system provide enhanced caller identification information to a called party. The system determines whether or not standard caller identification information associated with a calling party can be provided to the called party. The system preferably determines whether the standard caller identification information is unavailable, incomplete or has been blocked. When the system determines that the standard caller identification information cannot be provided, the system transmits a request for audible caller identification information to the calling party. If the calling party provides the requested audible caller identification information, the audible caller identification information is transmitted to the called party. The called party is thus provided with information about the calling party that can assist the called party in deciding whether or not to answer the call.

Abstract: An apparatus for simulating the behavior of a biological neuron. A chargecarrying component is fabricated from semiconductor material and is disposed above a semiconductor substrate. The charge-carrying component is separated from the substrate, and substantially surrounded, by an isolating material, such as an oxide (e.g., silicon dioxide). In order to control the quantity of charge carried on the charge-carrying component, a charge injector (104) is disposed adjacent to the charge-carrying component and is configured to controllably transfer charge to the charge-carrying component. Similarly, a drain (106) is disposed adjacent to the charge-carrying component and configured to controllably transfer charge away from the charge-carrying component. The charge injector (104) and drain (106) of the preferred embodiment are structurally similar to charge injectors and drains conventionally used in EEPROM technology. To generate an output, a charge sensor (116) disposed in proximity with a charge sensing location on the charge-carrying component, and an output (130) is provided and disposed in communication with the charge sensor (116). As a result, the output delivers an electric signal that is indicative of the charge sensed by the charge sensor.

IPC: F02D41/02
Filed: 1999-11-09
Abstract: An apparatus and method is provided for automatic shut-off of a combustion engine driving a fluid pump of a fluid displacement unit in order to protect the fluid displacement unit from damage due to excessively high running speeds. The apparatus includes a latching circuit that trips when an attention electrical signal exceeds a shut-off threshold potential. A biased electrical switching component inhibits fuel ignition for a period of time allowing the engine to spin down to rest. The latching circuit and switching component thus prevent the engine from being flooded to which prior-art devices are prone when their mechanical latches are not reset. Furthermore, this apparatus and method saves the engine from overspeeding damage to which prior-art devices are prone when a user blocks the mechanical latching action.
