To protect against the health and safety risks that accompany accidental post-use needle sticks, a medical needle assembly equipped with a safety cap is described. The disclosed medical needle assembly generally includes a needle hub, a needle having a magnetized distal end, and a removable safety cap attached to and extending radially from the needle hub. In another embodiment, the removable safety cap is attached to a sheath that covers the needle. The safety cap includes a magnet and a retainer disposed between the first and second ends of the cap. The retainer is configured to prevent withdrawal of the needle once the needle perforates the retainer and the safety cap encloses the distal end of the needle.

The receiver is provided which comprises a mixer, a low pass filter coupled to the mixer and a plurality of gain controllers serially coupled to an output of the low pass filter (LPF). A plurality of analog-to-digital converters (ADCs) is coupled so that an input of a first of the ADCs is coupled to the output of the LPF. An input of each of a remaining portion of the ADCs is individually coupled to a corresponding output of each of the serially coupled gain blocks. An output path traced from the output of the LPF to an output of each of the analog-to-digital converters may be referred to as a processing path. Each processing path may comprise a gain controller and an ADC, except for the first processing path, which may have an ADC coupled directly to the output of the LPF.

Thermoformed or hot melt extruded pharmaceutical compositions containing an active pharmaceutical ingredient, acrylic enteric polymer and plasticizer are disclosed. Methods of making the same as well as various pharmaceutical dosage forms are also disclosed. In preferred aspects, a thermoformable mixture is in a powder form and includes an active ingredient, plasticizer, acrylic polymer and optional excipients which enhance the performance of the extrudate after being incorporated into a dosage form.

A syringe for at least one of drawing a fluid into the syringe and dispensing a fluid substance therefrom, the syringe comprising a barrel comprising an inner surface defining a cylindrical chamber for retaining a dispensable fluid therein, a distal end terminating in a tip to which a needle is coupleable, and an open proximal end; an elongated sleeve positionable within the cylindrical chamber, the sleeve having an outer diameter dimensioned to be friction-fittable in the cylindrical chamber; a plunger having a distal end and a proximal end, at least one of which is capped, the plunger being dimensioned to be slideable within the elongated sleeve when positioned therein, and wherein any sliding of the plunger inside the sleeve does not cause the movement of the elongated sleeve inside the cylindrical chamber of the barrel; a plunger rod, dimensioned for engaging the plunger and forcing the plunger slideably within the sleeve in the directions towards and away from the tip; wherein the sliding of the plunger towards the tip causes the fluid to be dispensed out the tip of the barrel and wherein the sliding of the plunger away from the tip causes the fluid to be drawn into the tip.

A communication system comprises a remote optimization server and a central optimization server adapted to communicate with each via a backhaul network. The central optimization server communicates with core network elements for data delivery. The servers provide access to local data servers, manage backhaul links, perform data caching, and optimize transmission of data that needs to be back-hauled in order to reduce data transfer via the backhaul network in a manner which is transparent to users and to core network elements. The servers perform compression and protocol optimization. The remote optimization server comprises a HTTP accelerator which uses client and server side optimization functions to retrieve a bundle of resources associated with a request for base HTML, and maintains a set of persistent connections over which all HTTP traffic is carried.
摘要:
A method of operation of a mobile network (1) comprising network core central nodes including a switching node and at least one remote node (4, 5) linked with the central nodes via a remote backhaul communication link (3). The method performs local connection of data or voice sessions. A remote node (4, 5) extracts, from signals, information concerning said devices to populate a database, and accesses said database when deciding whether to connect the call locally. The information includes device capability information including codec capabilities of the originating and terminating devices (MS-A, B, C). A remote node alters signalling information concerning codec capabilities of at least one of the devices (MS-A, B, C) to force use of the same codecs during the session. In one example, the information is extracted from a Bearer Capability field in a Call Confirmed message sent back from the terminating device and stored in the database for use in subsequent decisions concerning local connections of sessions. The invention allows legal intercept operations and is adaptive to handover conditions.
