525191, 525216, 525232, 525240

Abstract:

The present invention provides a polymer blend suitable for use as a film or a coating, the polymer blend including from 1 to 99% by weight of a metallocene-produced VLDPE polymer having a density less than 0. 916 g/cm , and from 1 to 99% by weight of an LDPE polymer having a density of from 0. 916 to 0. 928 g/cm wherein the sum of (a) and (b) is 100%. The VLDPE polymer can have a melt index of from 6 to 15 dg/min, or from 9 to 12 dg/min. The present invention further provides polymeric films extrusion cast from such polymer blends, and articles having a flexible substrate and a polymeric film extrusion-coated on the substrate.

Abstract:

An apparatus for limiting a data transfer bandwidth through handshake suppression is configured to generate a first reset signal, generate a second reset signal a predetermined number of clock cycles after generating the first reset signal, generate a handshake count representing a number of receptions, between the first reset signal and the second reset signal, of a first Ready to Send (“RTS”) handshake signal and a first Ready to Receive (“RTR”) handshake signal, and disable a second RTR handshake signal and the first RTS handshake signal based on a comparison of the handshake count and a maximum value.

US Classification:

348448, 348441, 348452, 348911

Abstract:

A combined de-interlacing and frame doubling system (and ) advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning. The de-interlacing and frame doubling system in accordance with present principles includes a frame memory mechanism (and ) for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit () pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.

Abstract:

A server in a network gathers textual information, such as news items, E-mail and the like. From that information, the server develops or identifies messages for use by individual subscribers. The same server that accumulates the text messages or another server in the network converts the textual information in each message to a sequence of speech synthesizer instructions. The converted messages, containing the sequences of speech synthesizer instructions, are transmitted to each identified subscriber's terminal device. A synthesizer in the terminal generates an audio waveform signal, representing the speech information, in response to the instructions. In the preferred embodiment, the terminals utilize concatenative type speech synthesizers, each of which has an associated vocabulary of stored fundamental sound samples. The instructions identify the sound samples, in order. The instructions also provide parameters for controlling characteristics of the signal generated during waveform synthesis for each sound sample in each sequence.

International Classification:

G01N 30/28

Abstract:

Described is a metering pump that may be used to meter volumes of sample in a chromatography system. The metering pump has a modular configuration that allows for separation of a head pod from a drive assembly for easy serviceability. The head pod includes a pump head, cartridge housing, seal wash housing and plunger. The drive assembly can be implemented in an inline drive configuration. Alternatively, the drive assembly can be implemented in an offset drive configuration in which a stepper motor is displaced laterally from other drive assembly components but is coupled through a belt and pulley system.
