Title: Two dimentionally grooved sanding pad
Inventor: DIXON WILLIAM
IPC: B24D15/02
Filed: 1990-11-30
Abstract: ABSTRACT OF THE DISCLOSURE   The present invention is directed toward flexible embossed supportive backings for coated abrasives, which are used with "sanding" tools.          The supportive backing is made from a flexible elastomeric material embossed on one side with a predetermined pattern.  The embossment pattern includes an uninterrupted narrow border along the edges that lay perpendicular to the primary of travel during use, a plurality of narrow grooves within the border which disrupt the surface area of the elastomeric material, and lines of severance that partially separate the edges of the material from its main body.   The surface acts as the supportive backing for a coated abrasive as it is worked over a roughened surface.  The grooves created by the embossment pattern allow the coated abrasive to deform as it encounters high points on a roughened surface, which allows the abrasive to surround the contours of the roughened surface and greatly increases the efficiency of the coated abrasive.  The grooves created by the embossment minimizes the work dust trapped between the coated abrasive and the supportive surface, which minimizes high points and uneven results.

Filed: 1991-04-02
Abstract: A hue compensation apparatus outputs hue-compensated data of a color designated by an input color selection signal of red, green and blue, responsive to red, green and blue input signals. The hue compensation apparatus uses first, second and third lookup table cir-cuits, a decoder, a polarizing circuit and a synthesizing circuit. The lookup table circuits output hue-compensated red, green and blue sig-nals in response to input red, green and blue signals, respectively. The decoder decodes the input color selection signal, and the polariza-tion circuit polarizes outputs from the first, second and third lookup table circuits according to an output of the decoder. The synthesizing circuit synthesizes the polarized output from the first, second and third lookup table circuits. The synthesizing circuit thus outputs a hue-compensated color signal whose color is designated by the color selection signal by synthesizing the polarized outputs from the polar-ization circuit.

Title: Common agent computer management system and method
Inventor: NIHART MIRIAM A
IPC: H04L12/24
Filed: 1991-06-07
Abstract: ABSTRACT OF THE DISCLOSURE          A computer system has a management system for performing management operations with respect to system components. Each component is capable of being controlled in accordance with  one  or  more  management  protocols.    One  or more management tools generate management commands that specify management operations to be performed by a specified set of system components.   The system includes a plurality of protocol  engines,  each  of which  implements  a  specific management  protocol  with  respect  to  a  set  of  system components.    Each  protocol  engine  responds  to system management  commands  by  generating  instructions  for performing the specified management operation in accordance with  a  predefined  management  protocol.    The  present invention provides a common agent interface which receives the instructions generated by a protocol engine and sends corresponding commands in a protocol non-specific format to the target system components which are the object of the specified management operation.   The common agent enables multiple management protocols to exist and interact with the components of a system.   As a particular protocol evolves,  it  can  be  upgraded  without  affecting the components of the operating systems that it interacts with. Also, new management protocols can be introduced into the system without having to modify the  components  of the operating systems that it interacts with.  The components of a  computer  system with the  common  agent need only provide a single management interface.  This interface can be accessed by multiple protocols allowing the component to be protocol non-specific and as such easier to write and maintain.            A-53050/GSW, PD90-0229

Title: Method for regulating power in a digital mobile telephony system
Inventor: LARSSON STIG M
IPC: H03G3/20
Filed: 1991-06-21
Abstract: The present invention relates to a method of regulating or adjusting the transmission power when transmitting signals between a mobile station and a base station in a digital mobile telephony system. The output power is regulated with the intention of constantly maintaining the transmission power at an optimum level, by which is meant that the transmission power is as low as possible such as to prevent unnecessary disturbance of neighbouring channels transmitting information on the same frequency, but sufficiently high for the transmitted information to be interpreted in the receiver. The measurement values of signal strength and signal-transmission quality are collected, the mean values of the signal strength and transmission quality are calculated on the basis of the collected measurement values. kith the aid of the calculated mean values, there is calculated an anticipated value of signal strength and transmission quality *(*Z_QQ) at the next time-point, provided that the transmission power is maintained unchanged in relation to the transmission power at the present or instant time-point. Finally, the transmission power at the next time-point is regulated on the basis of these anticipated values. The transmission power is increased when the anticipated transmission quality is poorer than the desired quality and is increased when the anticipated quality is higher than the highest permitted quality or when the anticipated signal strength is greater than the maximum permitted value. The transmission power is otherwise maintained unchanged.
