  • Patent number: 11630038
    Abstract: A method and system are described for processing tissues according to particular processing protocols that are established based on time-of-flight measurements as a processing fluid is diffused into a tissue sample. In one embodiment, measurement of the time it takes about 70% ethanol to diffuse into a tissue sample is used to predict the time it will take to diffuse other processing fluids into the same or similar tissue samples. Advantageously, the disclosed method and system can reduce overall processing times and help ensure that only samples that require similar processing conditions are batched together.

  • Patent number: 11567037
    Abstract: Sensors, methods, and computer program products for air bubble detection and fluid composition determinations are provided. An example sensor device for use with fluid flow systems includes a force pulse generator coupled with a fluid flow system that emits a force pulse and a force pulse sensor coupled with the fluid flow system. The force pulse sensor receives the force pulse emitted by the force pulse generator and determines the fluid flow system's transient response to the force pulse. Based upon the transient response, the force pulse sensor determines an operating condition of the fluid flow system. The operating condition may be indicative of the presence of an air bubble within the fluid flow system or may be indicative of a composition of a fluid within the fluid flow system. The force pulse sensor may further determine the amplitude and rate of decay of the transient response.
