Abstract: A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

Abstract: An ambient condition detector incorporates a common radiant energy source to carry out a first, sensing, function and a second, information transmitting function. The source can generate a beam to implement a fire sensing function. In addition, modulated radiant energy emitted from the source can be remotely sensed to determine detector status or internal parameter values. In an alternate embodiment, a source of radiant energy can be configured at an exterior periphery of the detector and information can be wirelessly transmitted therefrom using one or more analog modulation processes.

Abstract: A software driven monitoring system includes a common control element coupled to a plurality of monitoring devices. The devices can indicate to the control element that a predetermined condition has been detected. Where the control element transmits a status inquiry command to the devices, those devices exhibiting the status provide the same indication to the control element as is indicative of the predetermined condition. One indication is a shunt or a short circuit of a medium between the common control element and the devices. An existing system can be upgraded by installing the control element, or upgrading an existing control program. Alternately, the devices can be installed in a system wherein the control element does not issue the status inquiry command. In those installations, the monitoring devices never issue a status reply as the required command is never received.

Abstract: An outer electrode for a combustion products detector comprising a cylindrical body including a plurality of first slats alternating with a plurality of second slats, the first slats being segments of a first surface of revolution, the second slats being skewed from a second surface of revolution having a different diameter from the first surface of revolution.
