Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

A multi-ladar sensor system is proposed for operating in dense environments where many ladar sensors are transmitting and receiving burst mode light in the same space, as may be typical of an automotive application. The system makes use of several techniques to reduce mutual interference between independently operating ladar sensors. In one embodiment, the individual ladar sensors are each assigned a wavelength of operation, and an optical receive filter for blocking the light transmitted at other wavelengths, an example of wavelength division multiplexing (WDM). Each ladar sensor, or platform, may also be assigned a pulse width selected from a list, and may use a pulse width discriminator circuit to separate pulses of interest from the clutter of other transmitters. Higher level coding, involving pulse sequences and code sequence correlation, may be implemented in a system of code division multiplexing, CDM. A digital processor optimized to execute mathematical operations is described which has a hardware implemented floating point divider, allowing for real time processing of received ladar pulses, and sequences of pulses.

The invention discloses an intelligent tree trunk white painting robot and belongs to the related fields of urban and garden greening equipment. The intelligent tree trunk white painting robot comprises a machine frame system, a robot traveling system, a lime slurry supply system, an automatic white painting execution system and a real-time detection system. Adopting a spray painting mode for white painting of tree trunks, the robot can automatically walk along a side pavement and quickly and efficiently spray lime solution onto trees along the side pavement. In a real-time detection system, a digital compass, a laser sensor and a vision system are adopted to realize the semi-automatic searching of tree trunks and tree trunk automatic positioning, an ultrasonic transducer is adopted to realize automatic obstacle avoidance, and the whole-process real-time monitoring with a personal computer (PC) and a programmable logic controller (PLC) is realized. When the intelligent tree trunk white painting robot is used, coating is saved and the painting effect is optimized; and the robot automatically performs white painting of trees along the side pavement, the working efficiency is improved, labor force is saved, and the goals of intelligent control and green environmental sanitation are fulfilled.

A vehicle sensor system consisting of video, radar, ultrasonic or laser sensors, oriented to obtain a 360 degree view around the vehicle for the purpose of developing a situation or scene awareness. The sensors may or may not have overlapping field of views, or support the same applications, but data will be shared by all. Orientation of the sensor to the vehicle body coordinates is critical in order to accurately assess threat and respond. This system describes methods based on measuring force and rotation on each sensor and computing a dynamic alignment to first each other, then second to the vehicle.
