Title: System for recording and reproducing a wide bandwidth video signal via a narrow bandwidth medium
Inventor: PATEL CHANDRAKANT B
IPC: H04N7/12
Filed: 1991-12-02
Granted: 1998-09-15
Abstract: An  encoder  processes  a  composite  video  signal including luminance and chrominance components into a folded limited bandwidth video signal including a low frequency  luminance  band component having  a  limited bandwidth and a high frequency luminance band component adaptively de-emphasized in amplitude and folded into the spectrum of the low frequency luminance band, along with a   chrominance-plus-motion   signal   containing   the chrominance component having encoded thereon a motion signal derived from and representative of image motion in the input video signal, and suitable for transmission or recording via a  limited bandwidth video medium and compatibly reproducible by narrow bandwidth reproduction devices due to the de-emphasized folded high luminance band and encoding  of the motion signal onto vacant portions  of  the  chrominance  component.   A  decoder converts the encoded signal into an unfolded wideband video  signal  including  a  baseband  luminance  signal containing the low band luminance component along with the unfolded high band luminance component re-emphasized to its original amplitude, together with the chrominance component signal separated from the encoded composite chrominance-plus-motion signal, whereby a full bandwidth image may be displayed.  The motion signal is utilized in the encoder for motion-adaptively pre-filtering the input luminance and is recovered in the decoder for motion-adaptively post-filtering the unfolded luminance.  The system can be applied to a narrowband VCR such as a VHS format VCR for providing improved resolution images on implementing playback devices with backward compatibility on conventional playback devices.

Relative movement between the probe electrode and the recording medium is effected by the moving mechanism.  A predetermined driving signal is inputted to the moving mechanism so that a predetermined movement of the probe electrode to the groove track is effected.  The physical phenomenon caused between the probe electrode and the recording medium is detected, so that the track groove is detected and a correction value for correcting the movement of the probe electrode from the driving signal on the basis of the timing of the detection.  The moving mechanism is controlled on the basis of the driving signal and the correction value.

Title: Telecommunication switching system having distributed dialing plan hierarchy
Inventor: BALES BRUCE MERRILL
IPC: H04Q3/545
Filed: 1992-10-22
Granted: 1997-04-08
Abstract: A system for distributing a numbering plan to switching nodes which are organized in a dialing plan hierarchy and for allowing an individual switching node to redistribute blocks of numbers to other switching nodes upon requests from those switching nodes to own the requested blocks of numbers. Further, the dialing plan hierarchy is automatically established upon system initialization with eachswitching node determining its position in that hierarchy. In addition, a switching node that needs to use only one number of a block owned by another switching node can request permission from the other switching node to use that telephone number for a telephone connected to the switching node. Such a use is referred to as hosting the telephone number. Hosting allows a telephone connected to one switching nodeto have a telephone number owned by another switching node and eliminates the constraint of requiring every telephone connected to a switching node to use a number from the block of numbers own by that switching node.

Title: Heel pillow mattress
Inventor: BALONICK ARNOLD
IPC: A61G7/05
Filed: 1993-11-24
Granted: 2005-11-08
Abstract: A mattress to prevent the creation of pressure sores having a heel pillow portion intended for use in healthcare facilities having replaceable parts is disclosed. The heel pillow mattress of the present invention is made of foam and has a cavity located at the foot area of the mattress for containing a pillow therein. A soft, resilient pillow insert contained within the cavity provides cushion for the heels of a patient lying on the mattress. A layer of foam covers the top of the cavity containing the pillow insert. This layer of foam has a low indentation force deflection (IFD) to provide a high degree of cushioning for the heels. This layer of foam together with the pillow insert beneath it, provide increased cushioning when a patient's heels apply a downward force on the mattress so that as the heels sink into the mattress, the foam layer and the pillow insert give way to the downward force of the heels and the mattress cradles the heels.      The degree to which the heels sink into the mattress is proportional to the load applied. The increased cushion and cradling effect of the heel pillow mattress of the present invention effectively prevents and avoids the creation of pressure sores. The heel pillow mattress is covered by a water and moisture impervious cover.
