  • Patent number: 12114597
    Abstract: A latching assembly (100?, 100?) for operably coupling a cutting deck (50) to an equipment frame (60) of a riding lawn care vehicle (10) may include a pivot arm (300, 400), and a latch member (310, 410). The pivot arm (300, 400) and the latch member (310, 410) may each be pivotally coupled to each other. The pivot arm (300, 400) and the latch member (310, 410) may also cooperate with each other to affix the cutting deck (50) to the equipment frame (60) in each of a service position and a working position.

  • Publication number: 20240210180
    Abstract: A computer system determines a selected path to be taken by a vehicle. The system monitors alternative paths for the vehicle; based on the monitoring, determines that the vehicle approaches at least two alternative paths having different properties; determines a probability of the vehicle taking each of the at least two alternative paths having different properties; compares the probabilities of the at least two alternative paths to each other; and based on a result of the comparison of the probabilities, selects a selected path amongst the at least two alternative paths.

  • Patent number: 11331512
    Abstract: A system and method for determining or estimating the presence and effect of light-attenuating inhomogeneities in tissue when performing medical treatment or diagnostics using optical members in tissue. The system and method comprising inserting a plurality of optical members into the tissue, and then measuring by emitting light through a sub-set of optical members at a time, while measuring the light collected by another sub-set of optical members. Combining said measurement data with a model for light propagation in tissue, and setting up a system of equations. Solving the unknown attenuation values from said system of equations.

  • Patent number: 9012869
    Abstract: A method and system for luminescence molecular imaging or tomography of a region of interest in a scattering medium is disclosed. The system comprises a non-linear luminescent marker material arranged in the scattering medium. Contrast and resolution of the imaging or tomography is thus improved. The non-linear marker is for instance configured to upconvert incoming light of an illumination wavelength. The non-linear power dependence of the marker enables further improvement of the imaging by using images taken with two or more excitation beams simultaneously.

  • Patent number: 8986358
    Abstract: A method and system for controlling and adjusting light in interstitial photodynamic light therapy (IPDT) in a subject is disclosed. More particularly, a method for controlling the light in interstitial tumor photodynamic light therapy is described using a calculation method for determination of status of tissue during the PDT treatment. The status is used in a feedback loop to control the continued PDT treatment. Methods are disclosed that constitute pre-treatment and realtime dosimetry modules for IPDT on the whole prostate glandular tissue. The method includes reconstruction of the target geometry, optimization of source fiber positions within this geometry, monitoring of the light attenuation during the treatment procedure and updating individual fiber irradiation times to take into account any variation in tissue light transmission.
