Patent number: 11746062Abstract: A process for preparing a porous ceramic body includes forming a green body with a mixture of ceramic material powder, binder material, and pore-forming particles. The process further includes extracting the binder material, decomposing the pore-forming particles, and removing residual organic materials from the green body at respective, progressively higher pre-firing temperatures. After these three stages, the green body is sintered at a still-higher temperature to form the porous ceramic body. Embodiments facilitate manufacturing and can render most or all surface grinding unnecessary, allowing electrode deposition directly onto substantially non-porous surfaces of the porous ceramic body that are naturally formed during sintering. Advantageously, the green body may be formed into net shape by injection molding the mixture that includes the pore-forming particles, and embodiments can result in porous ceramic bodies that are much thicker than currently available, with better structural integrity.Type: GrantFiled: March 9, 2021Date of Patent: September 5, 2023Assignee: AIRMAR TECHNOLOGY CORPORATIONInventors: Barry J. Robinson, Brian G. Pazol

Patent number: 10972833Abstract: A method of optimizing acoustic transducer performance, and corresponding system, can include mechanically coupling a transducer to a fluid barrier, calibrating the acoustic transducer by measuring response as a function of drive frequency to determine one or more optimum drive frequencies, optimized for the transducer actually coupled to the fluid barrier, and storing the one or more optimum drive frequencies for use in operating the acoustic transducer. Shims may also be used between the transducer and fluid barrier, such as a boat hull, to optimize transducer performance. Embodiments can enable improved in-hull transducer depth sounding, as well as improved fluid level measurements in tanks.Type: GrantFiled: January 24, 2018Date of Patent: April 6, 2021Assignee: AIRMAR TECHNOLOGY CORPORATIONInventors: Kenneth D.
