Abstract: A needleless injection system includes a pusher that pushes a plunger within a tapered bore of a cartridge. The pusher includes a nib, the tip of which is a ball.

Abstract: An apparatus for use in injectate delivery includes an actuator including a linkage, a force generating mechanism mechanically coupled to the linkage, and a controller coupled to the force generating mechanism. The force generating mechanism includes a passive force generator and an active force generator. In operation and on the basis of a control signal, the controller is configured to control the force generating mechanism to provide an input force to the linkage that is a combination of the first force provided by the passive force generator and a second force provided by the active force generator.

Abstract: An apparatus comprising a practice device for practice of hitting a tennis ball includes a server configured for serving the tennis ball to a user, a net disposed to intercept a flight of the tennis ball after the tennis bell has been hit by the user using a racket and to direct the captured tennis ball back towards the server to be served again to the user, an image detector configured to observe the tennis ball as the tennis ball hurtles towards the net, and a processor. The processor determines, based at least in part on image frames received from the image detector, data indicative of the tennis ball's virtual landing spot. This virtual landing spot is an estimate of where the tennis ball would have landed on an opposing court had the tennis ball not been intercepted by the net.

Abstract: An apparatus for injectate delivery includes a cartridge, a linear actuator, a rotary motor mechanically coupled the actuator, and a controller coupled to the motor. The controller controls a linear motion of the actuator by controlling an electrical input supplied to the motor in a first interval during which the motor is stationary with the linear actuator engaged with the cartridge to displace an injectate in the cartridge, a second interval following the first interval during which the controller accelerates the motor from stationary to a first speed selected to create a jet of the injectate from the cartridge with a velocity sufficient to pierce human tissue to a subcutaneous depth, a third interval during which the controller maintains the motor at or above the first speed, and a fourth interval during which the controller decelerates the motor to a second speed to deliver the injectate at the subcutaneous depth.

Abstract: An active injection guide concurrently monitors surface contact and an instantaneous contact force along an injection axis of an injector in order to ensure that the injector is properly positioned on a patient before an injection can be initiated.

Abstract: A micro electro mechanical system is provided. The micro electro mechanical system includes a first part bonded to a second part by a structural adhesive interface. The structural adhesive interface includes a conductive structural adhesive portion, and a non-conductive structural adhesive portion at least partially surrounding the conductive structural adhesive portion. The conductive structural adhesive portion and the non-conductive structural adhesive portion have a thixotropy index greater than one.

Abstract: An adapter for use with an injection device includes a first end, a second end and a first longitudinal axis extending from the first end and the second end. The adapter also includes a chamber defined by a sidewall between the first end and second end and a nozzle having a passageway extending through the sidewall, the passageway having an input at the chamber, an output at an outer surface of the body and a passageway axis extending from the input to the output, the passageway axis being angularly offset from the longitudinal axis of the channel. A cartridge can include such an adapter.
