A method and system is provided for emulating individual JTAG devices in a multiple device boundary scan chain. The method includes coupling an emulator to the scan chain, and obtaining the topology of the scan chain. One device within the scan chain is then selected, and at least one other device within the scan chain is placed into bypass mode. Emulation instructions are sent to the scan chain, so that the emulation instructions bypass the at least one other device and are executed by the one ...

Apparatus for measuring the sensory condition of the skin. The apparatus includes means for repeatably projecting and retracting a pair of probes and for repeatably varying the separation between the probes so that the Von Frey and Weber two point discrimination tests may be performed objectively. The apparatus also includes means for measuring skin temperature and electrical resistance with a unitary wand and for measuring the pinch and grip forces which may be applied by the fingers and hand.

The present invention provides a power operated instrument stand for use, for example during eye examinations. The instrument stand has a motorized arm to aid in precise placement of instrumentation. The instrument stand also has control circuitry for room lighting levels, patient chair positioning and slit lamp operation. The instrument stand may be controlled through an attached control pad, or a remote control.

A support system for at least one of ophthalmic and optometric instruments. A first instrument supporting member is pivotable between a first storage position and a first use position. A second instrument supporting member is moveable between a second storage position and a second use position. The patient can be sequentially examined, in any order, by the first and second instruments while remaining in a test position.

A nasotracheal tube holder comprises a substantially straight projection having a laterally curved, trough-like surface mounted on a base for securing said projection to a person's head such that the projection is adapted to receive in longitudinally aligned relation the protruding end of a nasotracheal tube in its applied working position. In a preferred embodiment a pair of laterally opposed tabs at the outer end of the projection serve as stop lugs for preventing a wrapping, such as tape, whi...

There is provided a curable substantially uniform mixture of an epoxysilicone, a polyarylonium salt and a compatibilizer in the form a mixture of a long chain alkyl substituted phenol and an alkane diol. The curable mixture is convertable to a non-toxic, tack free adherent release coating for pressure sensitive adhesives.

A polyamide precursor of a polybenzazole polymer is prepared by reacting an aromatic bis(alkenyl)ester with a ring forming, aromatic diamine. The precursor can be prepared in an organic solvent for the monomers to form a soluble polyamide precursor which can be subsequently cyclocondensed to form a PBX polymer. A polybenzoxazole precursor is prepared by the reaction of a bis(alkenyl)ester and a bis(ortho-hydroxyamine). A polybenzazole polymer is easily prepared by heating the polyamide, PBX prec...

Integrated transmitters and controllers for use in monitoring process variables. A transmitter and controller for monitoring and controlling a process variable in a process control loop comprises a transmitter for producing a digital signal indicative of the process variable's state, and a digital controller supplied with the digital signal from the transmitter responsive to the digital signal, and further interfaced in a process control loop for controlling the process variable in response to t...

An endotracheal tube holder comprises a substantially straight projection having a laterally curved, trough-like surface mounted on a base for securing said projection to a person's head such that the projection is adapted to receive in longitudinally aligned relation the protruding end of an endotracheal tube in its applied working position. A pair of laterally opposed tabs at the outer end of the projection serve as stop lugs for preventing a wrapping, such as tape, which binds the tube to the...
