The present invention is a system for and method of adjusting hearing aids (130) by discrete frequency ranges (FIG. 3a); continual tuning and reprogramming of the hearing aid is accomplished in real time via iterations between a patient (with hearing aid in ear, 120) and an audiologist (131). A test tone or other sound is played and the patient gives feedback on the test tone's suitability (such as loudness). The hearing aid (130) is further tuned and reprogrammed accordingly as the sound is replayed and the patient (120) gives additional feedback. These steps continue until the patient (120) considers the hearing optimized, compensating for both the patient's hearing loss and individual preferences in the discrete frequency ranges. The following are twelve commonly tested frequency ranges: 125 Hz, 250 Hz, 750 Hz, 1000 Hz, 1500 Hz, 2000 Hz, 3000 Hz, 4000 Hz, 5000 Hz, 6000 Hz, 8000 Hz, and 10,000 Hz.

A method and an apparatus facilitate the processing of a core structure for a composite sandwich structure. The core has an open three-dimensional structure and is not self-supporting due to an insufficient strength or stiffness. The method involves temporarily providing a support arrangement on the core structure to mechanically support and stabilize it, then subjecting the supported core structure to the desired processing, and then separating and removing the core structure and the support arrangement from one another. The processing can involve immersion into a processing liquid such as a curable resin, or mechanical machining operations. The support arrangement preferably includes a core impression that is surfacially form-fitting on a structured surface of the core structure. The apparatus includes a support arrangement including a core impression to be disposed on a surface of the core structure. The core impression may be formed of a polymer, a metal, or a casting material.

A plurality of test target chips on a test target wafer are simultaneously and electrically coupled to a plurality of chips on a test wafer via a wafer contactor. Each chip on the test wafer has a test circuit for conducting an operation test on each chip on the test target wafer. Since the test circuit is in a one-to-one relationship with respect to the test target chip, and is arranged on the test wafer other than the test target wafer, the many chips can be simultaneously tested in parallel during the wafer test without increasing an area of the test target chips.

The invention provides a modified method for improving the hydrothermal stability of a molecular sieve in an FCC catalyst with high efficiency. The method is characterized in that: the molecular sieve is added to a phosphorus containing water solution and reacted for a period of time under conditions of certain pH value, reaction temperature and reaction pressure; and the mixture is filtered, dried and roasted to form the modified molecular sieve. In the modified molecular sieve, the content of dry base is 90 to 99 weight percent, and the content of phosphorus is 1 to 10 weight percent according to oxides. By a water washing test, the retention rate of the modified elements of the modified molecular sieve is 92.6 percent. Compared with the unmodified molecular sieve model catalyst and the molecular sieve model catalysts modified by other methods, the model catalyst prepared by the modified molecular sieve has higher hydrothermal stability and micro active property.
