Title: End-reinforced bookbinding strip for impact resistance
Inventor: GROSWITH CHARLES T
IPC: B42D1/06
Filed: 1990-08-10
Granted: 1993-09-16
Abstract: A binding system, employing a first plastic elongated strip with spaced integral studs and a second plastic elongated strip having similarly spaced apertures and recesses, is provided which resists impact forces caused by dropping a bound book. A first fixed spacing of studs is provided along a mid-span portion of the first strip and a second fixed smaller spacing of studs provided at both end portions of the first strip which reinforces the end portions against stud breakage or extrusion caused by impact forces. In the preferred embodiment, the three end studs at each end of the strip are spaced at a second fixed spacing distance stud center-to-center of only one-half the first fixed spacing at the long mid-span portion of the strip. In another embodiment, a generally second fixed spacing of one-third the mid-span spacing with the at least two of the end portion studs being staggered from the center longitudinal axis of the strip is shown. An additional embodiment includes one or more integral studs of the end portions of the strip having a substantially greater cross-sectional area than the studs in the mid-span portion of the strip. In each embodiment, the binding is end reinforced against impact forces.

Title: Multiplexed digital packet telephone system
Inventor: GOLLUB RAPHAEL
IPC: H04J99/00
Filed: 1986-08-20
Granted: 1991-01-03
Abstract: An efficient system for simultaneously conveying a large number of telephone conversations over a much smaller number of relatively low-bandwidth digital communication channels is disclosed. Each incoming telephone speech signal is filtered, periodically sampled, and digitized. An efficient computational speech compression algorithm is applied to transform a sequence of digitized speech samples into a much shorter sequence of compression variables. The compression variable sequence is further processed to construct a minimum-length bit string, and an identifying header is appended to form a packet. Only a few packets containing information on representative background noise are generated during pauses in speech, thereby conserving digital bandwidth. The packets are queued and transmitted asynchronously over the first available serial digital communication channel. Numerical feedback to the compression algorithm is employed which results in the packet size being reduced during periods of high digital channel usage. Packet header information is utilized to establish a "virtual circuit" between sender and receiver.

Title: A circuit for measuring the level of an electrical signal and including offset correction means, and application thereof to amplifiers having automatic gain control
IPC: H03F3/45
Filed: 1990-12-21
Granted: 1993-03-11
Abstract: The circuit measures the level of an electrical signal, possibly with reference to a reference voltage. It can, with advantage, be applied to amplifiers with automatic gain control. 
<??>The circuit measures the level of an input electrical signal (Ve) and consists of an input amplifier (1), biased by a bias voltage, receiving this input signal (Ve) and producing an output signal (Vs), followed by a detector (2), itself followed by an integrator (3) delivering an integration signal (Vi). These three units form a measurement channel, the said integration signal (Vi) being the sum of a signal with a level proportional to the level of the said input signal (Ve) and an offset signal. The measuring circuit also incorporates a generator (6) producing a reference voltage (Vr), a compensation module (4) receiving the reference voltage (Vr) and producing a compensation signal (Vc), and a differential measuring amplifier (5) receiving the integration and compensation signals and producing a measurement signal (Vm). The bias voltage is the reference voltage (Vr). The compensation module (4) comprises stages corresponding to the units in the measurement channel in order to pass on the reference voltage (Vr) in conditions similar in all respects to those of the measurement channel. This produces a correction signal having the same value as the offset signal, the correction signal being included in the compensation signal (Vc).
