Abstract: A mercury detection system that includes a flow cell having a mercury sensor, a light source and a light detector is provided. The mercury sensor includes a transparent substrate and a submonolayer of mercury absorbing nanoparticles, e.g., gold nanoparticles, on a surface of the substrate. Methods of determining whether mercury is present in a sample using the mercury sensors are also provided. The subject mercury detection systems and methods find use in a variety of different applications, including mercury detecting applications.

Abstract: Techniques for generating prediction of risks of medical outcomes and benefit scores for medical interventions, with imputation of missing patient data values, are disclosed.

Abstract: A device for securing a gated enclosure includes a latch including a power lock motor and a bolt. The power lock motor is operable to engage the bolt with a catch portion of a pin protruding from the gate when the gate is closed, thereby preventing extraction of the pin from the device. The device includes a switch operated by a key to activate the latch. The device can include an electric horn, a light, a battery, and circuitry powered by the battery, the circuitry operable to send a signal to one or more of the horn and the light.

Abstract: A home medical supervision and monitoring system with computer-controlled base station provides medical supervision of an individual and controls medical monitoring, environmental, and safety devices. Modular electronic components, a real-time operating system and multilevel application software provide decision-making choices to inform a monitoring service or the like if a medical crisis is occurring or an adverse environmental or safety condition exists. Subsystems include medical monitoring devices to control and monitor specific medical conditions. If a crisis is detected, predefined physician instructions are implemented. A daily medical supervision subsystem records messages to be played back at preset intervals to supervise the individual's daily medical, safety or environmental activities under control of application software. A personal distress call subsystem can contact a monitoring service by pushing a distress button or by voice activating a communication circuit via a speaker telephone.

Abstract: A spout assembly is provided with a discharge conduit defining a flow passage having an inlet and an outlet. The conduit has a unitary internal wall defining an aperture and a shoulder around the aperture upon which is disposed a foraminous, flow restricting member. The flow restricting member is held in position against the shoulder by a plug which is threadingly engaged with the discharge conduit in an access opening spaced from, but aligned with, the internal wall shoulder.
