Title: Telecommunication device for the deaf with automatic self-identification
Inventor: ENGELKE ROBERT M
IPC: H04M11/04
Filed: 1993-05-19
Abstract: A telecommunication device for the deaf (12, 14, 16, 20, 22, 24, 26, 28) includes a self-identification sequence which auto-matically commences upon the initiation of communication with the device. The self-identification sequence consists of a series of characters which may be separated by pauses and the device listens during the pauses to see if TDD communication has been established. The purpose of the character string is so that a receiving station can identify, with a low rate of error, a calling TDD and therefore switch the incoming call to a TDD equipped operator. This capability is particularly useful for emergency service operators (911 services) which must be able to handle incoming TDD calls with a maximun of efficiency and a minimum of error.

Title: Molding arrangement to achieve short mold cycle time
Inventor: LUST VICTOR
IPC: B29D11/00
Filed: 1995-06-08
Abstract: An arrangement for molding a front or back polystyrene mold half which is used, with a second complementary back or front mold half, for subsequent molding of a soft contact lens such as a hydrogel soft contact lens. The arrangement is designed with heat flow considerations in mind to minimize the molding cycle time, while producing uniformly precise and accurate optical quality mold halves. Each mold half defines a convex curved surface and a concave curved surface spaced therefrom, with one of the surfaces defining an optical quality curved surface for the soft contact lens. A heated molding machine introduces molten polystyrene through a hot runner system to a plurality of mold cavities, each of which defines an optical quality curved surface and also a second noncritical surface. The optical quality surface of the mold cavity is positioned further away from the heated hot runner side of the mold than the second surface, which allows faster cooling of the optical quality surface of the mold cavity. This allows quicker setting and locking of minimal temperature residual stresses on the optical quality side of the mold half and a faster molding cycle time. Each mold cavity has a first insert on the optical quality side of the mold cavity and a second insert on the second side. Each of the first and second inserts has a circumferential cooling passageway defined therearound or in proximity for the first inserts, and also includes a bubbler positioned internally therein. Coolant is circulated in a turbulent mode through the circumferential passageways -39- 1 and also through the bubblers against inner surfaces of the insert to provide rapid cooling of the mold cavity.

Title: Method of Transmitting Orthogonal Frequency Division Multiplexing Signal and Receiver Thereof
Inventor: HARADA YASUO
IPC: H04L27/26
Filed: 1996-01-04
Abstract: An orthogonal frequency division multiplexing signal transmitted from the transmitting end to the receiving end intermittently includes a particular symbol SO having a predetermined particular pattern in addition to a symbol Sm including data to be transmitted. At the receiving end, the variation in the receiving level and/or the variation in the frequency band of a received signal are detected and corrected on the basis of the received particular symbol SO. Since the particular symbol SO has a particular pattern, the variation in the level and/or the variation in the frequency are strongly correlated with the variation in the receiving level and/or the variation in the frequency band of the received signal. Consequently, the variation in the receiving level and/or the variation in the frequency band of the received signal can be accurately detected from the particular symbol SO and consequently high-precision correction can be made.
