Abstract: A faceplate of a showerhead has a bottom side that faces a plasma generation region and a top side that faces a plenum into which a process gas is supplied during operation of a substrate processing system. The faceplate includes apertures formed through the bottom side and openings formed through the top side. Each of the apertures is formed to extend through a portion of an overall thickness of the faceplate to intersect with at least one of the openings to form a corresponding flow path for process gas through the faceplate. Each of the apertures has a cross-section that has a hollow cathode discharge suppression dimension in at least one direction. Each of the openings has a cross-section that has a smallest cross-sectional dimension that is greater than the hollow cathode discharge suppression dimension.

Abstract: An infant care apparatus includes a base, a patient-support portion carried by the base, a canopy situated above the patient-support portion, and a mechanism for vertically raising and lowering the canopy relative to the patient-support portion. A convective heating system is operable to provide heated air into a space defined between the patient-support portion and the canopy. A radiant heater is coupled to the canopy and is operable to direct radiant heat toward the patient-support portion. A control system controls the operation of the convective heating system and the radiant heater.

Abstract: An infant thermal support device which provides convective heat transfer similar to an incubator yet which allows for unlimited care provider access to the infant without compromising the infant's thermal environment. The device has an infant support with head and foot ends and lateral sides, and provides a heated curtain of air traveling over an infant on the support to maintain the temperature of the infant at an appropriate level. Vertically oriented curtains of air travel upwardly from the lateral edges and at least one end of the support. The device provides warmth to the infant on the support by virtue of the heated air curtain, and the vertically oriented air curtains reduced perturbations of the heated air curtain caused by physical disturbances adjacent to the device such that a canopy enclosing the device is not required. The device further comprises a raisable and lowerable canopy and infrared heater, such that the device can function as either an infant radiant warmer, an incubator or both.

Abstract: A patient support and environmental control apparatus comprises a frame and an upwardly-facing patient-support surface carried by the frame. An air curtain generator is mounted to the frame. The air curtain generator provides first and second curtains of air. The patient-support surface has a perimeter and the first and second curtains of air originate adjacent to the perimeter and converge at a point positioned to lie above the patient-support surface. The first and second curtains of air cooperate with the patient-support surface to define a patient space.

Abstract: A patient-support apparatus includes a base and a patient-support surface carried above the base. The patient-support apparatus further includes an indicator and a unit having at least one of a noise sensor and a light sensor which generates a sensor data signal. The patient-support apparatus further includes a control system coupled to the indicator and the at least one sensor. The control system is configured to process the sensor data signal and activate the indicator only when the sensor data signal exceeds a preset threshold level. The patient-support apparatus further includes a mechanism coupled to the control system to permit adjustment of the preset threshold level.

Abstract: A patient support system having an environmentally controlled area over the patient including a frame with a patient support thereon and a moveable canopy thereover. The support is generally rectangular and is provided with a vertical fluid curtain at its perimeter on each of its four sides. The four vertical curtains are deflected inwardly by the canopy to provide the environmentally controlled area over the patient and with a fluid return to the perimeter to provide a closed fluid path. The air curtains can be heated and/or have water vapor added thereto. An infrared heater is provided in the canopy for a second source of heat. An integrated control system is also provided.

Abstract: An infant simulator for modeling the thermal properties of premature infants comprises a head, a pair of arms, a pair of legs, and a torso, a fluid circuit connecting and supplying fluid from a fluid source to the pair of arms, pair of legs and torso, a pump in the torso for circulating fluid through the simulator, and a synthetic skin for simulating insensible water loss in a premature infant.

Abstract: A loose probe alarm in which a temperature responsive element (14) arranged for attachment to a body is periodically heated (20, 22, 26) and the effects of self-heating of the temperature responsive element are monitored (32, 36, 38) to determine whether the temperature responsive element has been dislodged from the body. The alarm is arranged to sense during the heating period of the temperature responsive element the difference in the amount of heat dissipated by the temperature responsive element when it remains in contact with the body to which it has been attached and when it has been dislodged from this body.
