Abstract: An improved fruit tester and method provides a plunger intrusion-type mechanism, a precision scale and an associated computer for control of the mechanism and for recordation, presentation and analysis of data sensed by the mechanism. An electrically powered variable speed motor carries an optical encoder to sense rotary direction and speed data, which is transmitted through circuitry to an associated computer for analysis to determine control data to maintain pre-programmed motor function. Computer software determines plunger position and resultant penetration into a fruit at either pre-determined plunger speed or constant plunger resistive pressure in fine increments over the plunger trajectory and stores this data in computer memory. The precision scale is used to determine the weight of the fruit before and after the penetration tests and the difference in weight is used to automatically calculate the Specific juice Content (SJC) of the fruit.

Abstract: Systems and methods for determining ICP based on parameters that can be measured using non-invasive or minimally invasive techniques are provided, wherein a non-linear relationship is used to determine ICP based on one or more variable inputs. The first variable input relates to one or more properties of a cranial blood vessel and/or blood flow, such as acoustic backscatter from an acoustic transducer having a focus trained on a cranial blood vessel, flow velocity in a cranial blood vessel, and the like. Additional variables, such as arterial blood pressure (ABP), may be used in combination with a first variable input relating to one or more properties of a cranial blood vessel, such as flow velocity of the middle cerebral artery (MCA) to derive ICP using a non-linear relationship.

Abstract: Systems and methods for determining ICP based on parameters that can be measured using non-invasive or minimally invasive techniques are provided. Systems for acquiring acoustic data from a desired target site in a subject's body using various types of acoustic source and detector elements are also provided, including single use acoustic source/detector combinations are also provided. Acoustic arrays for use with these systems may include multiple capacitive micro-machined ultrasound transducer (cMUT) elements, and may include a combination of different types of acoustic arrays. Methods of targeting localized sites within a broad target area based on acoustic data having various properties are also disclosed.
