Abstract: A system and method for aligning a target to an equipped vehicle for calibration of a sensor on the equipped vehicle includes a vehicle support stand upon which an equipped vehicle is disposed in an established known position for calibration of the sensor, and a target adjustment stand configured to moveably hold a target. The target adjustment stand is configured to position the target into a calibration position relative to the sensor on the equipped vehicle based on the established known position of the equipped vehicle on the vehicle support stand whereby the sensor is able to be calibrated using the target.

Abstract: A mobile system and method of calibrating an ADAS sensor of a vehicle by aligning a target with the sensor, where a transport vehicle is equipped with a target adjustment stand for transporting to the vehicle, which is initially nominally positioned in front of the target adjustment stand that includes a movable target mount configured to support a target, with the target adjustment stand including one or more actuators for adjusting the position of the target mount. A computer system is used to determine an orientation of the vehicle relative to the target adjustment stand, with the position of the target mount being adjusted based on the determined orientation of the vehicle relative to the target adjustment stand. Upon properly orienting the target mount, and the target supported thereon, a calibration routine is performed whereby the sensor is calibrated using the target.

Abstract: A system for determining alignment characteristics of a wheel assembly of a vehicle includes one or more optical gauges that are selectively attached to a wheel assembly, with the optical gauge including a mounting base having an underside that is affixed to the wheel assembly and including a gauge piece comprising a known dimension. The system further includes a light projector that projects light onto the optical gauge when attached to the wheel assembly, a digital imager, and a controller. The digital imager is configured to image light from the light projector that is reflected from the optical gauge, and the controller is configured to calculate a distance from the optical gauge based on the imaged light that is reflected from the optical gauge and the known dimension of the gauge piece. The mounting base may be a tape that is adhesively affixed to the wheel assembly.

Abstract: A jet injection device with a fluid chamber in a housing member for holding about 0.02 ml to about 3 ml of a medicament. An injection-assisting needle has an injection end that extends from the housing for inserting into a patient to a depth of up to about 5 mm. A force-generating source is configured to apply a pressure reaching about 100-1000 psi to the medicament in the chamber to expel the medicament through the injecting end of the needle.

Abstract: A needle assisted jet injector and method for jet injecting medicament are disclosed. In one embodiment of the injector, the needle is retractably located within an injector nozzle assembly. Upon activation of the force generating source, a portion of the needle extends past the nozzle assembly and penetrates the outer layer of skin to deliver the medicament via jet injection to a deeper region. After activation, the needle retracts back into the nozzle assembly. In another embodiment, the needle is fixed to the end of the nozzle assembly. In both embodiments, the length of the portion of the needle that penetrates the skin is less than 5 mm.

Abstract: A probe and nozzle assembly for reducing the pressure at which a needleless injector must deliver medicament for proper delivery are disclosed. In one embodiment of the probe, the probe is retractably located within an injector nozzle assembly. Upon activation of the energy source a portion of the probe extends past the nozzle assembly to deliver the medicament through a discharge channel. After activation the probe retracts back into the nozzle assembly. In another embodiment, the probe is fixed to the end of the nozzle assembly. In both embodiments the ratio of discharge channel length to diameter is greater than 6/1.

Abstract: The invention relates to methods and devices for delivering medicament by jet injection to an injection site in a patient. The method includes inserting a needle into an insertion point, wherein the needle has a length of less than 5 mm and is operatively associated with an orifice in a nozzle assembly in fluid communication with an ampule chamber containing the medicament. The needle extends less than about 5 mm from the nozzle assembly orifice when the medicament is expelled. Next, a force generating mechanism is activated, and a pressure wall member that is operatively associated with the force generating member moves in response to the activation of the force generating mechanism at a speed sufficient to jet inject the medicament from the ampule chamber through the orifice and needle under a pressure of less than about 4000 psi to deliver a substantial portion of the medicament through the needle and past the insertion point to the injection site.
