Abstract: Provided herein modified dehalogenases have extended surface loop regions that provide a location for internal fusion insertions and modulate binding interaction and activation of environmentally-sensitive chemistries.

Abstract: A patient monitoring system. The patient monitoring system comprises a camera and a processing unit in communication with the camera. The processing unit is configured to determine a safe zone around the patient based at least in part on an analysis of one or more initial images received from the camera. The processing unit is further configured to determine whether the patient has exited the safe zone based at least in part on an analysis of one or more subsequent images received from the camera. The processing unit is also configured to trigger an alarm in response to determining that the patient has exited the safe zone.

Abstract: A bimetallic tube comprising a copper-base alloy and a reactive metal such as titanium, is produced by assembling concentrically a tubular member of each of such materials and interposing a layer of copper, nickel or silver between them, forming a bond between the reactive metal and the copper, nickel or silver and extruding the assembly. The bimetallic tube is useful for heat exchange purposes when corrosive fluids are involved and has better heat transfer properties than an all-reactive metal tube.
