Abstract: Applicants have disclosed an “Articulating Headgear Connector for Respiratory Masks” which allows three-dimensional movement of the headgear connector to alleviate the mechanical forces incurred from a wearer's head movement, and thus maintain an effective seal. In the preferred embodiment, the invention comprises: a CPAP mask having a plastic shell; the mask has a stub tube extending outwardly from the shell; a headgear connector mounted loosely onto the stub tube; a T-shaped nib on the elbow guides the headgear's movement; whereby the headgear connector can slide forward on the stub tube (i.e., move along the Z axis), guided by the nib; and, whereby the headgear connector can rock (i.e., about the X-Y axes) and its sides seesaw on the stub tube (i.e., along the Z-axis), with the amount of rotation and seesawing limited by the nib.

Abstract: A hand rail adapted for mounting on a wall and having free ends spaced from such wall, and a coupling between the free, opposite ends of the rail for supporting return members which span the space between the rail and the wall surface. Each coupling has a socket at each end thereof, one of such sockets being adapted for the accommodation of the free end of the rail and the other of such sockets being adopted for the accommodation of a free end of the return member. Each socket has an inner surface which tapers in a direction inwardly of the coupling and also has an internal shoulder which limits the extent to which the rail or return member may extend into the coupling.

Abstract: A sink attachment having a basin, a drain tube, and a sealing member is disclosed. The sink attachment provides for simultaneously draining tap water or other liquids and sealing the sink. The attachment may be relocated without having to remove the sealing member from the sink drain.

Abstract: An accessory (40) for a computer mouse (18) includes a multistrand accessory conductor (42) for transmitting location signals and acceptance signals having a first coupling (44) for coupling a first end of the conductor (42) to the coupling (26) of a computer mouse assembly (19) and a second coupling (46) for coupling a second end of the conductor (42) to a coupling (22) of a computer (10). The accessory further includes a remote acceptance switch (54) coupled to the strands of the multistrand accessory conductor including a hand-operated button (56) for producing an acceptance signal similar to the acceptance signal produced by an acceptance switch (38) of the computer mouse (18). Thus, a cursor location generated by movement of the computer mouse can be accepted in a memory of the computer either by activation of the mouse acceptance switch or the remote acceptance switch.

Abstract: A myocardial lead for applying electrical pulses to a myocardium includes a relatively large electrode body of a metal, exhibiting high stress fatigue and corrosion resistance properties, a short stud of a metal containing platinum is partially inserted into the electrode body, with the stud portion extending out of the body defining the electrode pin. The stud is electron beam welded to the body. The myocardial lead also includes a distal wire, which consists of a plurality of flexible wire coils of the same metal as the electrode body and are covered by a flexible rubber sleeve. At one end, the wire coils pass through a cavity in the electrode body, with the coils' portion extending therefrom being wrapped around the electrode body and welded thereto. The distal wire extends to a source of electrical pulses. A platinum winding is wrapped around the electrode pin and is attached at one end to the electrode body.

Abstract: The master unit of an intercom in a building includes a digital code selector operating a digital coder for transmission of remote unit identification code signals to the intercom receivers of several remote units for alerting persons at such respective units. Each remote unit includes a receiver for receiving both conversation transmission and an identification code signal, reference signal means and a signal comparator for comparing identification code signals received by its receiver with its reference identification code signal. Reception by a remote unit of the appropriate identification code signal conditions its receiver to produce an audible call or alerting signal from an electronic call signal received by the receiver of that remote unit from the transmitter of the master unit. The call signal is generated electronically and supplied to the transmitter of the master unit for transmission to all of the remote units.
