Abstract: A unitary multilumen cranial bolt for use in multimodal monitoring of a plurality of physiological parameters in brain tissue incorporates a plurality of lumens, each lumen directing a catheter borne sensor through a bore hole in the cranium and into brain tissue of a patient. The lumens are configured to cause the catheters to splay outward as they enter the cranial cavity and reach their intended depth of penetration. Each lumen is associated with a guide. The guides are adapted for use with introducers that enable fragile and/or flexible sensors to be introduced into brain tissue. Each catheter borne sensor can be positioned and repositioned within brain tissue independently of all other sensors.

Abstract: An edema monitor uses patient-specific measurements of tissue conductivity and tissue perfusion and an empirically developed perfusion coefficient of thermal conductivity to obtain tissue intravascular water and tissue extravacular water components of tissue total water. Edema is an excess of tissue extravacular water. A value for edema is obtained by deducting from the obtained value for tissue extravacular water a normal value for tissue extravacular water.

Abstract: The system assesses the endothelial function of a subject. Particularly, peripheral tissue perfusion measurements taken in a subject are compared to reference perfusion data and the comparison yields the assessment of endothelial function. The reference may be data indicative of peripheral tissue perfusion in a healthy person. Also, peripheral tissue perfusion measurements taken in a subject when perfusion is in an unperturbed state (the reference) can be compared to perfusion measurements taken promptly after a challenge to normal or unperturbed tissue perfusion of the subject.

Abstract: Methods and apparatus for determining blood flow in tissue are disclosed. The methods and apparatus are used to establish a baseline for both thermal properties of the tissue and non-physiologic conditions. Periodic changes in either or both constituents of the baseline are determined and, when the changes correspond to a need for a new baseline, a new baseline is established.

Abstract: A storage apparatus for boxes containing fruit includes a cabinet having side walls, a rear wall, front wall portions, and a cover portion. The front wall portions together define an access opening for insertion of a stack of the boxes. Each of the side walls include an outer wall and an inner wall separated from the outer wall by a space, and a plurality of vertically oriented partitions disposed between the inner and outer walls. Each of the inner walls include a plurality of apertures, with each of the apertures being associated with a unique one of the air flow channels to allow the air in that channel to impact boxes of fruit located adjacent that aperture. Damper means close off one or more apertures as boxes are removed to enhance airflow through the remaining apertures.

Abstract: Disclosed are methods and apparatus for determining blood flow in tissue. Particularly methods and apparatus are disclosed for establishing baseline thermal properties for the tissue and providing one or more steps for periodically determining changes in the tissue thermal properties that correspond to a need for a new baseline and establishing the new baseline.

Abstract: A technique is disclosed for determining blood flow in a living body by changing the thermal energy level in the venous blood flow path and determining temperatures in both the venous and arterial blood flow paths. Blood flow is calculated as a function of the change in energy level and the temperature differences in the venous and arterial blood flow paths.

Abstract: A storage apparatus for boxes containing fruit includes a cabinet having side walls, a rear wall, front wall portions, and a cover portion. The front wall portions together define an access opening for insertion and withdrawal of a stack of the boxes. Each of the side walls include an outer wall and an inner wall separated from the outer wall by a space, and a plurality of vertically oriented partitions disposed between the inner and outer walls where the partitions are spaced from one another and are in intimate contact with the inner and outer side walls. In this way, the inner and outer side walls define, with the partitions, airflow channels. The cover portion is positioned atop the front, side and rear walls, and supports blowers disposed atop the airflow channels of each side wall and conduit means interconnecting the blowers and the channels for fluidly communicating said blowers with said air flow channels.

Abstract: A technique for determining blood flow in a living body by changing the thermal energy level by a predetermined amount at a site in a blood flow path and detecting temperatures at locations upstream and downstream of the site. The temperature difference at such locations is determined and the blood flow is calculated as a function of the change in energy level and of the temperature differences measured prior to and following the change in energy level.

Abstract: A shock monitor comprising one or more probes, for measuring physiological conditions indicative of shock, and a controller for calculating blood flow values, as an indicator of the state-of-shock, is disclosed. The probe is used to introduce an input signal and produces an output signal, which represents the state-of-shock of the tissue in communication with the probe. The output signal is used to calculate a blood flow value.

Abstract: A technique for quantifying perfusion and removing a biopsy sample at a site in a living body wherein an instrument having a perfusion sensor is introduced into the body at a site to be investigated to there interrogate the tissue. The biopsy specimen is collected when the perfusion sensor produces a signal indicative of perfused, viable tissue.
