Filed: 1994-03-28
Abstract: SMARTCARD TELEPHONE ADJUNCT Abstract A telephone adjunct, or a telephone which incorporates the telephone adjunct, that includes a smartcard reader provides users with enhanced capabilities. One basic concept disclosed is the ability of smartcards to interact with a service provider called by the user. A salient feature of the invention is that the user can interact with the service provider in the normal mode (e.g., through voice communication) and, at will, switch over to digital communication between the smartcard and the service provider. Normal mode operation can be reinstated upon termination of the digital communication by the smartcard. In one embodiment, the adjunct contains the smartcard reader coupled to a modem and the modem is coupled to a network port of the adjunct through a switch. The user's telephone is coupled to the network port of the adjunct through the same switch. This switch is under influence of a controller that is sensitive to selected control signals, such as voice energy from the user's telephone, voice or carrier frequency from the network and carrier or data signals from the modem.

Title: Speech coder employing analysis-by-synthesis techniques with a pulse excitation
Inventor: CELLARIO LUCA
IPC: G10L19/12
Filed: 1994-04-08
Abstract: SPEECH CODER EMPLOYING ANALYSIS-BY-SYNTHESIS TECHNIQUES WITH A PULSE EXCITATION                         ABSTRACT          In an analysis-by-synthesis coder, the original speech signal undergoes small time shifts to match in time the signal to be coded with the replica reproduced by the long-term synthesis filter.  The shift is determined at each subframe by an exhaustive search within a range of possible values so at to minimize the error signal energy.  Once the optimal shift has been determined, the optimal excitation is searched for.  The excitation is chosen in a codebook containing words with very few pulses arranged in a deterministic structure, which words are all obtained from a limited number of key words.  The deterministic codebook structure allows a fast search for the optimal excitation,  without need of storing the codebook and actually performing the synthesis filterings of the candidate excitations.

Abstract: 2131323 9317732 PCTABS00025 Improvements to a hypodermic needle disposed within a retractable sleeve comprised of a plurality of longitudinal slats extending between a base carrying the needle and an outer end covering the needle's tip. There is a releasable base attaching to a device such as a syringe. The base supports a hard cover used to attach and release the needle and sleeve. A bell end provides a point of sliding on the needle behind the tip and viewing of the tip when transparent. The tip is placed in a pre-established orientation and the sleeve is marked so that the needle can be positioned before the sleeve is retracted. Where a spring-biased collar is used over the sleeve, the base has gripping tabs to hold the spring, the collar has an extended area for sliding stacking of the spring upon retraction, and another extended area for protecting the front holding projections when the sleeve is extended. A dental version has the slats at the rear to fold outward outside the patient's mouth. By reversing the front projections, the sleeve locks up after one use. A strongback adjacent the front end of the sleeve helps in creating a repeatable folding pattern. A gripping ring aids in manually retracting the sleeve. Living hinges also help in creating a repeatable folding pattern. The living hinges may include indentations representing an identification number.

Title: Learning method and apparatus
Inventor: ABBOTT PETER S
IPC: G09B19/00
Filed: 1994-09-20
Abstract: This invention is a self-study learning method and apparatus for use with any written material.  The learning is accomplished by the method of blacking out certain portions of written matter to allow the user to test his or her recall, memory and/or problem solving skills.  In this method,  a  student uses  a colored marker to highlight certain portions of the written matter so that the written matter is still visible, a second complementary colored marker is also used to highlight other portions of the written matter.  A transparency of the identical color to the first marker allows the written matter highlighted by the first marker to be seen, however, the highlighting of the second marker appears black, obliterating the written matter.  Similarly, a transparency of the identical color to the second marker enables viewing of the written matter highlighted by the second marker, but blackens the portions highlighted by the first marker.

Filed: 1994-10-20
Abstract: POOL COVER ABSTRACT A pool cover is formed by a plurality of hexagonal pads which float separately on the pool surface and orient themselves to cover the majority of the pool service in edge to edge floating relationship. The pads can be removed from the pool and stacked together on top of each other up to for example 5 or 6 high with the top cover panel being shaped to define a seat or a table top surface. The seat is supplemented by a seat back structure which is snap fastened into place on top of the seating surface. Each side edge of the hexagonal panel has a hand hold arrangement with downwardly projecting underside ribs to assist stacking. A central lock bar or key extends through vertically aligned holes in the panels to lock them in the stack. The cover panels thus can be connected together to form pool furniture around the pool to provide a useful function rather than merely requiring storage space.
