Abstract: A system and method to automatically initiate an injection procedure of a medicament into a patient. In the system, a delivery assembly includes an injector for infusing the medicament into the patient. Further, the system includes a monitor for detecting a parameter characteristic of the procedure, for instance, a pressure indicative of a partial vacuum between the injector and the injection site, a pressure exerted by the patient against the delivery assembly, a conductance, a capacitance, or an optical blood reading. Also, the system includes a timer for determining compliance of the parameter within a predetermined range during a first time interval. In response to the timer, an actuator initiates the injection procedure at the expiration of the first time interval. Further, the actuator may stop the injection procedure if the parameter is outside the predetermined range during a second time interval.
Abstract: An ophthalmic imaging system includes a light source, focusing optics, compensating optics, and a computer that coordinates both of the optics to optimize the Diffraction Limited Point Spread Function (DL-PSF) of the imaging light beam. In detail, the compensating optics includes a customized phase plate that provides substantially complete compensation for static aberrations introduced by an eye into the imaging light beam. Further, the computer measures an operational error signal that results from dynamic aberrations. The computer then uses the error signal to control the compensating optics and thereby optimize the DL-PSF by compensating for both static and dynamic aberrations. For an alternate embodiment, an active mirror can be included in the compensating optics to provide additional compensation for the dynamic aberrations.
Abstract: A system and method are provided for simulating a Laser Induced Optical Breakdown (LIOB) protocol to establish a surgical LIOB treatment for a patient. In the system, a library of finite element models characterizing various visual defects in corneas are programmed into a computer. Further, a library of nomograms indicating specific LIOB protocols for correcting respective visual defects are programmed into the computer. As a result, a model and a corresponding nomogram may be selected in view of a patient's diagnostic information. Further, the selected model may be individualized with the diagnostic information to more precisely characterize the patient's visual defects. Thereafter, the computer simulates the indicated LIOB protocol on the individualized model in order to achieve a desired corneal configuration. When the desired corneal configuration is achieved, the final treatment plan may be determined.
Abstract: A cabin door assembly is provided for use with a pressurized aircraft. The assembly includes two door halves for engaging the fuselage of the aircraft. Structurally, each door half includes a waist section integral with an adjoining tapered section. Further, the assembly includes an activator that is mounted on the fuselage and attached to the door halves. Specifically, the activator is attached to each door half to concertedly move each door half between a closed configuration and an open configuration. In the closed configuration, the door halves are sealed to the fuselage and to each other for pressurization of the aircraft. In the open configuration, the door halves extend outwardly from the fuselage to allow for aircraft ingress and egress.

Abstract: A system for positioning the eye of a patient in alignment with a laser unit for laser surgery includes an alignment device that is mounted on the laser unit. It also includes a patient interface having a curved contact lens. Additionally, a clamp with an attached suction ring can be engaged with the interface to hold the lens against the eye of the patient. Thus, when the interface is joined with the alignment device, the lens is positioned against the eye of the patient at a predetermined distance from the laser unit for laser surgery.
Abstract: A system and method is provided for metering vehicular traffic. Specifically, the system uses a computer to prevent delays as vehicles transition from a greater number of toll lanes to a lesser number of travel lanes. Toll collection devices are used to send a ready signal to a computer to indicate a vehicle is ready to leave a start point. The computer receives ready signals from the toll collection devices and uses a pre-programmed departure schedule to queue the vehicles. After the vehicles are queued, the computer uses time delay variables to ensure efficient traffic flow between the toll lanes of the plaza and the travel lanes of the bridge or tunnel. An indicator signal responsive to a departure signal sent by the computer is employed to direct vehicles from a start point towards a travel lane.
Abstract: A system and method for storing encrypted electronic data using a transmission Control Protocol (TCP), requires leaving both the header and the first 48 bytes of the “0” data packet in the data area of the TCP format in clear text. Consequently, the data can be routed to a main address (storage facility), and then to a sub-address (storage device) for storage. A single compression/encryption operation can be accomplished, before storage, at the host (server), the network switch, or the final storage device.
Abstract: A system and method for moving vehicular traffic in a single lane through a control zone requires creation of a control protocol. The protocol establishes a spacing distance “s” and a speed “v” for each vehicle in the control zone. A computer then controls movement of a visible signal through the control zone in accordance with the established protocol. Electronic regulators monitor the distance “s” between the signal and the vehicle, and the system alarms when “s” becomes greater than a predetermined distance “d”.
Abstract: A method and device for photoablation is disclosed wherein photoablation occurs along the interface between a material having a lower energy ablation threshold and a material having a higher energy ablation threshold. The method and device utilize a laser beam having a beam energy density which is less than the higher energy ablation threshold and greater than or equal to the lower energy ablation threshold. By directing such a laser beam to the interface, the material having the lower energy threshold is photoablated while the material having the higher energy threshold is largely unaffected.

Abstract: A system for chemically disposing energetic material enclosed in assembled devices includes a porous basket. The porous basket forms an enclosed chamber for receiving the assembled devices. Further, the basket is supported by a rotatable basket arm that is, in turn, connected to a lifting arm. In addition to these structures, the system includes a tank that holds a hydrolysis solution. The tank is positioned to allow the lifting arm to submerge the basket into the solution. After submersion, the basket arm rotates the basket in the solution to flow the hydrolysis solution into contact with the assembled devices therein. As a result, the assembled devices react with the solution so that the solution penetrates the assembled devices, allowing the solution to contact and react with the energetic material to render the energetic material non-energetic.

Abstract: A method and device are provided for manufacturing a unitary caul sheet to be used in creating a composite material fuselage for an airplane. Specifically, a generally tubular shaped tool having a hollow interior cavity defining a fuselage IML surface is provided. In the method, a caul sheet material such as polyurea is applied to the IML surface before an armature is inserted into the interior cavity of the tool. Then, a filler material is introduced between the armature and the caul sheet material. Further, steam is injected to form the filler material into an infrastructure. Then, the caul sheet material is cured before the tool is removed from the caul sheet material to expose the caul sheet to receive composite material.
Abstract: A system and method for simulating a corneal reconfiguration in response to LIOB uses a computer-programmed, finite element model. The model has a plurality of elements; with each element pre-programmed with coefficients based on diagnostic corneal data. Collectively the coefficients replicate biomechanical properties of the cornea. In use, designated biomechanical characteristics on a plurality of selected elements (i.e. selected coefficients) are minimized to simulate LIOB in an actual cornea. A computer then measures the resultant reconfiguration of the cornea model to assess an actual cornea's response to LIOB.

Abstract: A system and method is provided for individually changing the peripheral cards of an electronic device, when the cards are operationally held inside a chassis on a rack cabinet. Included is a platform for holding the peripheral cards, and a slide carrier mounted on the chassis for moving the platform with cards into and out of the internal chamber of the chassis. Importantly, this is done while the chassis remains stationary on the rack cabinet. When moved outside the chassis chamber, each peripheral card can be individually handled (i.e. installed or removed) without contact or operational interference with other peripheral cards held on the platform. Adapters on the platform can be adjusted to accommodate the dimensions of each peripheral card.
Abstract: A system for fueling a plasma includes a gyrotron for radiating microwave energy into a waveguide. Also included is a module having a deuterium-tritium (DT) fuel pellet, a diamond, quartz or sapphire window, and a pusher medium located between the pellet and window that is made of frozen deuterium (D2) and metallic particles. With the module in the waveguide, the gyrotron is activated. Radiation from the gyrotron is then directed into the waveguide and through the window to cause the inducement of current in the metal particles, causing the particles to become hot. The absorbed microwave energy is then transferred to the pusher medium by conduction resulting in a gaseous expansion of the pusher medium. This ejects the pellet from the waveguide and into the plasma.
Abstract: An aircraft wing made of a composite material, and its method of manufacture, require a plurality of kabobs (i.e. substantially rectangular shaped hollow tubes having an open end and a closed end). Of these kabobs, several are aligned end-to-end, to create a section. Several sections are then positioned side-by-side and covered by a layer of composite material to define an aerodynamic surface for the wing. The juxtaposed sections also establish spar webs for the wing, and the closed ends of the juxtaposed sections establish transverse ribs for the wing. Thus, the kabobs form the main load-bearing member of the wing. The sections of composite material are co-cured with the composite material of the aerodynamic surface.
