Abstract: To prevent accidental needle stick injuries, a syringe has a plunger configured to pull the syringe needle into the syringe barrel after clinical use. The syringe has an additional safety feature that restricts subsequent movement of the plunger. After the needle is pulled entirely into the barrel, movement of the plunger is restricted by a notch on the barrel to prevent the needle tip from being pushed accidentally through the barrel wall.

Abstract: A DC-DC switched inductor boost converter with reduced switch voltage stress including two inductors and two active switches. The two inductors may be configured to charge in parallel when the two active switches are turned on, and the two inductors may be configured to discharge in series when the two active switches are turned off A Switched Inductor Boost (SI-B) converter is proposed with reduced voltage stress across active switches to achieve higher output voltage. The SI-B converter configuration is transformer-less and derived by replacing the diode of the classical switched inductor structure with an active switch. As a result, compared to the existing transformer-less high step-up converter or switched inductor boost converter, certain embodiments have the merit that the switch voltage stress across the active switch is less than the output voltage.

Abstract: The typical service to deliver multimedia content is evolved Multimedia Broadcast Multicast Service (eMBMS). However, the eMBMS is a service-oriented network architecture requiring a pre-defined and pre-established user service to stream a live video. The content provider must be a multicast service provider to use the eMBMS services, which many typical content providers are not. Accordingly, the present disclosure provides a live video streaming network architecture that enhances the eMBMS architecture to enable service-less multicast delivery. The provided system includes a virtual network function service running on an application server (AS) that identifies potential multicast scenarios based on user requests for a live video stream within a confined area.
