A syringe ( 100 ) has a syringe body ( 1 ) hollow on the inside, a plunger ( 4 ) slidable in the syringe body ( 1 ) and provided at the rear with a shaft ( 41 ) that can be operated manually, an injection needle ( 2 ) engageable to the front end ( 13 ) of the syringe body ( 1 ) with a needle-carrier ( 20 ), and a guard mechanism ( 200 ) having a sleeve ( 5 ), a spring ( 7 ) and a abutment member (...

A carrying element (10) holding a sleeve (31) to be moved transversally in order to engage the appropriate gears (3,4), is attached to the transmission shaft (2). The synchronizing unit (1) is assembled of an inner (5) and an outer ring (6) as well as of an intermediate ring (7) positioned between them. An extension (30) exceeding in a right angle from the inner ring (5) serves as a securing eleme...

A test method is described for determining radiated radio frequency (RF) receiver sensitivity may include determining a bit error rate (BER) versus traffic channel (TCH) power level function for an initial channel, determining an estimated TCH power level for a subsequent channel based upon the BER versus TCH power level function and a desired BER, and measuring a BER of a subsequent channel based...

A test method for determining radio frequency (RF) path loss between an RF source and an RF receiver for a plurality of RF channels in a given RF frequency may include determining RF path losses for selected RF channels within the given RF frequency band, and determining an RF path loss function based upon the RF path losses of the selected RF channels. The method may further include determining a...
