Abstract: An apparatus for working a wet coating, such as render material, applied to a surface, the apparatus comprising: an actuator arranged to move an arm across a surface having a wet coating applied thereon; a controller configured to move the arm across the surface along a tool path; and a tool head mounted to the arm, the tool head comprising a compliance module and a tool mounted to the compliance module such that the tool is movable in a stroke direction towards the surface relative to the arm. The compliance module comprises a biasing module arranged to urge the tool in the stroke direction to maintain contact between the tool and the wet coating such that the tool works the wet coating as the arm moves across the surface.

Abstract: A gimbaled multispectral imaging system and method is described herein. In an general embodiment, the gimbaled multispectral imaging system has a cross support that defines a first gimbal axis and a second gimbal axis, wherein the cross support is rotatable about the first gimbal axis. The gimbaled multispectral imaging system comprises a telescope that fixed to an upper end of the cross support, such that rotation of the cross support about the first gimbal axis causes the tilt of the telescope to alter. The gimbaled multispectral imaging system includes optics that facilitate on-gimbal detection of visible light and off-gimbal detection of infrared light.

Abstract: A patient monitoring system according to one embodiment includes a real-time wetness sensor configured to detect the rate of change in wetness occurring within an associated diaper, and automatically adjusting the sensitivity of the sensor to account for a wetness event unrelated to urination. A monitoring unit may be utilized in such a manner that the monitoring system controller-monitors the wetness sensor and generates data associated with detected-wetness events relative to the diaper. A wireless transmitter configured with the monitoring unit and in communication with the monitoring system controller may be further utilized to send the generated data, through a host computer, to a caregiver unit having a caregiver system controller in communication with the host computer. The caregiver can then check the status of the patient, provide a service, and annotate the patients history by transmitting the recorded observation and service provided back to the base station.
