Abstract: A plastic blow molded container (10) including a coextruded blow molding (12) has a wall (22) including: (a) an inner lay-er (26) of a virgin plastic; (b) an inner intermediate layer (28) of recycled plastic which is relatively dark; (c) an outer intermediate layer (30) of an opaque plastic that visually hides the dark recycled plastic;  and (d) an outer layer (32) of a pigmented plastic of a lighter color which is not visually distorted by the darker inner intermediate layer (28) of recycled plastic due to the opaqueness of the outer intermediate layer (30). Titanium dioxide is preferably utilized to provide the opaqueness of the outer intermediate layer (30) whose plastic may be either virgin or recycled. The inner layer (26) of virgin plastic, the outer intermediate layer (30) of opaque plastic and the outer layer (32) of pigmented plastic each has a thickness that is at least about 0.1 of the total thickness of the wall, and the inner intermediate layer (28) of recycled plastic normally will have a thickness on the order of about 0.55 to 0.65 of the total thickness of the wall. The construction of the container has particular utility when the wall (22) including each of its layers is made of high density polyethylene.

Title: Linear prediction coefficient generation during frame erasure or packet loss
Inventor: CHEN JUIN-HWEY
IPC: G10L19/00
Filed: 1995-03-07
Granted: 1999-01-12
Abstract: A speech coding system robust to frame erasure (or packet loss) is described. Illustrative embodiments are directed to a modified version of CCITT standard G.728. In the event of frame erasure, vectors of an excitation signal are synthesized based on previously stored excitation signal vectors generated during non-erased frames. This synthesis differs for voiced and non-voiced speech. During erased frames, linear prediction filter coefficients are synthesized as a weighted extrapolation of a set of linear prediction filter coefficients determined during non-erased frames. The weighting factor is a number less than 1. This weighting accomplishes a bandwidth-expansion of peaks in the frequency response of a linear predictive filter. Computational complexity during erased frames is reduced through the elimination of certain computations needed during non-erased frames only. This reduction in computational complexity offsets additional computation required for excitation signal synthesis and linear prediction filter coefficient generation during erased frames.

Title: A hybrid equalizer arrangement for use in data communications equipment
Inventor: GADOT SHLOMO
IPC: H03H21/00
Filed: 1995-09-13
Granted: 2000-01-25
Abstract: A hybrid type of decision feedback equalizer (DFE) structure that approaches optimal DFE performance is described. The hybrid DFE includes both an intersymbol interference DFE (ISI-DFE) and a noise predictive DFE (NP-DFE). The hybrid DFE structure is designed so that one form of tap values dominates over the other. This allows only the dominate tap values to be used by the transmitter during precoding and reduces the transmitter complexity. In particular, a hybrid DFE is designed so that the I(z) coefficient values dominate over the N(z) coefficient values, where the notation I(z) and N(z), as known in the art, represent the resulting coefficient values after adaptation of the ISI-DFE and the NP-DFE, respectively. A respective Tomlinson precoding scheme in the transmitter uses only the I(z) values. Since only the I(z) values are used in the precoder of the transmitter, the NP-DFE of the receiver is kept active during the communications phase. Conveniently, the continued use of the NP-DFE in the receiver allows the receiver to track small changes in the channel.

Abstract: A method for spatially controlling the period and amplitude of Bragg filters in an optical medium having a longitudinal axis that is sensitive to at least some wavelength of electromagnetic radiation. A phase mask of period ? is laid close to the optical medium at an angle .alpha. with respect to the longitudinal axis of the optical medium. A single beam of electromagnetic radiation is directed at an incidence angle ? with respect to normal incidence on the phase mask so that the radiation is diffracted, resulting in an interference pattern having a period P impinged into the optical medium so that the period P of the interference pattern may be altered by changing the incidence angle ? or the angle .alpha.. This method is simpler, more flexible and more suitable for mass production than existing methods.

Abstract: A small and inexpensive planar dielectric line that can be easily connected to electronic parts, such as ICs, and having lower conductor losses. The planar dielectric line includes a dielectric substrate having first and second surfaces opposedly facing each other. A first slot having a predetermined width is interposed between first and second electrodes on the first surface of the dielectric substrate. A second slot having the same width as the first slot is disposed between third and fourth electrodes on the second surface of the dielectric substrate. The first and second slots opposedly face each other. The permittivity and the thickness of the dielectric substrate are determined so that a plane electromagnetic wave can propagate in a propagation region of the substrate interposed between the first and second slots while being totally reflected on the first surface of the substrate adjacent to the first slot and the second surface of the substrate near the second slot. First and second conductive plates may be spaced on both sides of the planar dielectric line. A further dielectric material may be disposed between the planar dielectric line and each of the conductive plates.      The above-described planar dielectric line may be part of an integrated circuit.

Granted: 2001-08-14
Abstract: A circuit that enhances the performance of the execution of a read-modify-write instruction type. The circuit provides hardware detection and decoding of various options specified by the instruction and greatly improves the performance and conserves space within a micro code control store (14). The circuit also detects anomalous cases and reports them to micro-code for special handling. The detection of the anomalous cases occurs dynamically and in parallel to instruction execution, thereby improving performance. Resulting condition codes are also provided simultaneously to the control program. The circuit operates in concert with a micro-code controlled mechanism to read a memory variable and, based on the specification of the instruction of the circuit selectively adds 1, subtracts 1, adds a 16-bit mask specified by the instruction, or subtracts the 16-bit mask, and returns the result to a central processor (12). Anomalous conditions that include overflow, invalid mask specification, and a special exchange option are all simultaneously detected and reported to the micro-code.
