Abstract: A method of testing a jaw force of an ultrasonic surgical instrument includes securing a blade of an end effector of the ultrasonic surgical instrument, clamping a jaw member of the end effector against the blade such that a sensor is received within a notch of the jaw member of the end effector, and measuring the jaw force of the end effector using the sensor.

Abstract: A surgical instrument includes a support frame defining first and second non-circular apertures each defining at least one stop surface, and a jaw member having a structural body including a proximal flange portion and an elongated distal portion extending distally from the proximal flange portion. A jaw liner is engaged with the elongated distal portion and defines a tissue-contacting surface. A first and a second pivot boss protrude from opposite sides of the proximal flange portion and at least partially into the first and second non-circular apertures, respectively. Each pivot boss is non-circular and defines at least one stop surface configured to mate with the at least one stop surface of the respective non-circular aperture to stop rotation of the jaw member before the jaw liner is forced into contact with a blade from the surgical instrument. A surgical instrument including such a jaw member is also provided.

Abstract: An improved lens focusing and referencing arrangement for an imaging system of the type which may include a photosensor array. The imaging system housing may include reference surfaces configured such that they contact the lens only near the ends thereof in order to minimize the effect of any irregularities in the reference surfaces.

Abstract: A magazine assembly containing numerous media units is disposed adjacent to a picker assembly. One of the two assemblies is normally stationary, while the other assembly is a traveling assembly. In either case, the two assemblies cooperate with one another to selectively provide the picker assembly with access to the media units that are stored in the magazine assembly. A motion reversal assembly is coupled to the normally stationary assembly and is engageable by the traveling assembly when it enters an end portion of its excursion path. When the motion reversal assembly is so engaged, it moves the normally stationary assembly in the direction opposite to that of the traveling assembly's movement. The effect is an apparent increase in the traveling assembly's available excursion length, which makes it possible for the picker assembly to access media slots that would otherwise be disposed in the dead spaces located on either end of the traveling assembly's excursion path.

Abstract: A solution to the problem of I/O card faults caused by spurious RF energy induced by ESD related currents in the vicinity of an aperture in a chassis is to reduce the efficiency of the radiating antenna created by the aperture and decouple any remaining spurious RF energy from any would-be receiving antenna in the I/O card. A conductive boot covers the I/O cable as it emerges from the chassis. The boot is physically attached and AC coupled (as well as probably ohmically connected) to the chassis at one end and tapers down to a small aperture at a distal end to permit egress of the I/O cable. The aperture at the distal end is considerable smaller than the aperture at the chassis, which is no longer visible to ESD induced currents anyway, since its edge has been replaced by the surface of the boot. The smaller aperture is a less efficient antenna at the frequencies of interest and it is now further removed from components that might act as receiving antennae.
