l.mft. Clly WmI. It.w4.r, M. HJS 2 Caltech Engineers Develop Hearing Device By DAVE SWAIM Stall Writer Dr. C.

Marslers, Pasadena orthodontist, spoke to a pair of young Caltech engineers about ptiorilies in Iheir work Marslers could nol hear himself speak, but he knew very well what he was saying. What he said to Glenn llighlower. 25. and John Denker, 20, was (hat new devices must be developed lo aid deaf people in communicating, especially in emergency situations. Marslers.

who in addition to his dental practice has years pushed the development of such aids, has been totally deaf himself for as long as lie can remember. Hightower. who holds a Caltech master's degree, and Denker. a senior in electrical engineering, took the hint They formed a small company which Ihey call APh Technological Consulting (APh: abbreviation for applied physics) specializing in technical projects lo aid the deaf One of their major projects, as suggested by Mavslers. is a small electronic teleprinter which will allow a deaf person tu by telephone lo another dear person who lias a similar device.

The idea is not brand new. Through Marsiers' work in past years about 10,000 families with deaf members have such units in (heir homes. Bui must of those in existence are old and obsolete CARL MITCHELL an agent of the Arcadia District lor Prudential Insurance recently celebrated his 20th year with the firm. Mitchell and his ivife Loisanne have two and reside in Ar- Pre -school Enrollment Now Open Arcadia Friends Church Pre school, located at 5705 Leiiore Ave. in Arcadia.

has becun taking enrollments for the 1975-75 fall term starting September, according to Mrs. Joanne l.ebs, director. Licensed by the Stale Department of Health, tlie Pre-scfiuol lias oeen in operation since 1968 when ii started with an enrollment of less than 40 students. There are presently nine classrooms available for children who will have reached their third birthday by Dec. 'I of this year.

A leaching and administrative staff of 10 plus nine aides and substitutes is maintained at the Preschool which olfers both Tuesday-Thursday and MoTid a Wertnesday-1'riday sessions based on group and individualized instruction and exploration, guided and independent activities which include number and alphabet recognition and concepts, reading readiness, science and social studies, field trips and numerous creative activities. In addition, basic Christian concepts are taught on daily basis. All lesson plans stress that each child learn as he is able to do so With some classes nearly completed, early enrollment is advised. Further inlormation concerning registration and tuition lees and required forms is available at the office and may be obtained by calling 4452130 Rousselot Asks Audit of Reserve A bill lo require an audit yf the Kederal Reserve Board and the Federal Heserve Banks and their branches each fiscal year was introduced in the Congress recently by Rep. John II Marino.

Referred to the Committee on Banking, Currency and Housing, 3056 would amend the Federal Heserve Act lo require ihe yearly audit of the Federal Reserve System by the comptroller general. The report would be made available to the Congress and Ihe President Fix months after the end of the fiscal year. Rousselot's bill would amend the l-ed Heserve Act lo also require the board to inform Congress 60 days prior to a change in rates. teletype machines which were purchased as surplus. The device the young engineers are building will be smaller, more sophisticated and less awkward lo use.

Also It will be quieter than the old clacking teletypes. Tlie noise, ol does nol bother deaf persons but dues create a problem for non-deaf members of the fid) lily Tlie new device, a prototype of which is nearly finished, weighs only 16 pounds, and is easily portable. One feature is that the words of the sender will appear in black ink on his printer, while words received will be red. Another feature is that the paper fed through the machine is only three inches wide, as compared to the R'i-incli wiile paper of the old machines. "Deaf people as a class are not wealthy." Hlghtower lliut reason we want lo build things lor them at a losI Ihey can afford." Another device the engineers are working on in their Al'li firm is a signal which flashes lighls on and off lliroujjhoul the house.

The pattern of the blinking lighls indicates whether tliev are responding to the doorbell, Ihe telephone, the kitchen timer, or an alarm of some kind. Imagine how difficult it is for a deaf person lo respond to emergency without something like this," Denker suid. A I'll also contemplates new devices to help develop soicc quality, by showing how Ihey sound on a screen. The devices would pick up vibrations from a chest transducer or a microphone and display (hern on an oscilloscope. It was noted that most deaf people speak in harsh nasal (ones, because they can't hear themselves.

"We are striving to help them feel and see their voices instead of hearing Iheni," Denker said. Iliglitowcr and Denker rely heavily on advice from llic experienced Dr. Marslers in their work for the deaf. When tlie APh firm needs money lo pursue its work, the two engineers and Caltech employed by them take on consulting jobs in computer programming or designing and other electronic, projects. "APh was conceived as a way of matching student talent with shorl-lerm technical needs of business, in-ituslry and scientific community." Hightower said.

Marslers keeps the firm headquartered in llightower's liome on South Grand Oaks Avenue supplied with ideas. We are inipitcd with this work because we think we can make a signifiuant contribution toward solving some rommunicatioiis problems of the deaf," Hightower said.
