摘要:
An interactive projection system, apparatus, and methods for their use are provided. The system includes a projection unit that projects an image of a user interface onto a projection surface. At least one vision sensor is provided that is configured to sense a location of an infrared light source. A computing device that is configured to execute applications to provide the user interface and to determine corresponding outputs based on inputs received by the vision sensor is also provided. An infrared input device, or stylus, is employed by a user to provide infrared light inputs at desired locations with respect to the projected user interface. Additionally, a plurality of styli, each emitting a different respective wavelength of infrared light is also useable to provide multiple simultaneous inputs to the system. An equal plurality of vision sensors may also be employed to separately sense inputs from a respective stylus.

A data receiving and illuminatable marking instrument and spaced emission source is disclosed. The marking instrument may be a full duplex marking apparatus that communicates with spaced emitters transmitting infrared electromagnetic energy encoded with unique data packets. The marking instrument illuminates a portion of the marking implement in response to the data received from the data transmitting device. A method for using the above invention likewise is disclosed.

A vehicle toy combination includes a wireless controlled toy vehicle having a mobile platform configured to move over a surface. A central controller on the platform is configured to control at least one aspect of the toy vehicle. A hand-held manually actuable wireless controller is configured to remotely control user selected movement of the toy vehicle. An optical receiver is attached to the platform to look downward on the surface and is coupled to the central controller. The receiver is configured to read a predetermined reflective pattern located on the surface over which the toy vehicle moves. Multiple vehicles can be controlled simultaneously with multiple wireless, manually operated controllers operating at the same frequency by initially synchronizing the controllers to transmit in non-overlapping windows.

The single use catheter has a lumen with a hydrophobic filter tip at one end. The lumen is divided into two parallel conduits. A first conduit terminates in a one-way valve. A syringe is attached to the one-way valve. Air, saline solution or sterilized water can be introduced through the one-way valve and inflate a cuff about the lumen. The second parallel conduit terminates in a charcoal filter for elimination of bowel gas. The one-way valve prevents deflation of the cuff unless the lumen is cut to allow the fluid from the cuff to exit and deflate the cuff.

An interactive drawing tablet is provided having a housing and at least one surface on which printed media is mounted. A delivery device is electrically coupled to the interactive drawing tablet and is configured to hold a writing implement. An array of emitters are embedded in the surface and configured to emit signals. The delivery device is configured to receive the signals from the emitters when the delivery device is brought into proximity to the individual emitters and thereby determine a location on the printed media. The interactive drawing tablet is equipped with a speaker for emitting audio media to the user of the tablet. The interactive drawing tablet provides a user with instructions as to actions that should be taken with respect to the printed media.
摘要:
The invention provides a method of inhibiting neovascularization in a subject. The method comprises administering to the subject an agent that interferes with fibronectin (Fn) matrix assembly in an amount effective to inhibit neovascularization. The invention also provides a method of identifying an agent that inhibits neovascularization. The method comprises detecting fibronectin (Fn) matrix assembly by stimulated endothelial cells cultured in three-dimensional culture gel in the presence and absence of an agent. A decrease in Fn matrix assembly in the presence of the agent compared to Fn matrix assembly in the absence of the agent is indicative of an agent that inhibits neovascularization. Alternatively, the method of identifying an agent that inhibits neovascularization comprises detecting changes in nuclear architecture in stimulated endothelial cells cultured in three-dimensional culture gel in the presence and absence of an agent. A reduction in nuclear architecture organization identifies an agent that inhibits neovascularization.

A motion-detecting note holder is disclosed. Such a note holder includes a note retention member, a motion sensor, a note-waiting indicator, and a controller in communication with the motion sensor and the note-waiting indicator. The controller, upon receiving a motion-detection signal from the motion sensor, causes the note-waiting indicator to provide a human-perceptible indication that a note is in the note retention member.
摘要:
A camera carrier is provided. The camera carrier includes a camera receptacle and an attachment system for mounting the receptacle to a person. The receptacle includes a member forming a lens receiving chamber sized and shaped to receive the lens of a camera therein with the lens being in a generally vertical position and pointing generally downward. The camera body limits the movement of the camera lens into the chamber. A retainer is provided to releaseably retain the camera mounted to the carrier and the lens within the chamber.
