Abstract: The present invention is a newel post anchoring device, for use with a newel post having a transverse bottom surface, for anchoring the newel post to a concrete floor.  The newel post anchoring device comprises a base having, a top with a periphery, a bottom load bearing surface, the top in surface engagement with the transverse bottom surface of the newel post. The load bearing surface is in surface engagement with the floor such that the base transmits the load of the newel post to the floor and the base elevates the newel post above the floor to minimize deterioration of the newel post. The newel post anchoring device further includes an anchor means preferably in the form of a wedge bolt for providing a rigid anchor to the floor and a fastening means preferably in the form of a threaded aperture in the base for securely fastening the anchor means to the base. The newel post anchoring device also includes an attaching means preferably in the form of screws passing through apertures in the base and into the newel post for attaching the base to the transverse bottom surface of the newel post, such that the anchor means, fastening means, and attaching means are not visible when the newel post is anchored to the floor.

Title: Intelligent memory management system and method
Inventor: ELLIS MICHAEL DEAN
IPC: H04H20/00
Filed: 1996-06-06
Abstract: A television electronic program guide intelligent memory management system and method automatically deletes the least valuable stored program information at that moment as free memory space is needed by the system. In advance of a program schedule update, the system executes a two-level memory "housekeeping"  operation in which the system first scans the memory to identify obsolete schedule information. If, after this sweep, there is insufficient memory available for the next update, the system performs a second-level memory "triage" operation wherein schedule information is automatically prioritized in accordance with pre-defined rules for assessing the current value of the information to each viewer based on program air time, channel and other variables relating to program utility. The system then deletes schedule information in ascending order of value, starting with the least valuable information, and continues until enough space is available in memory to store the schedule update.
Patent CA-2223316-A1 (CA)
Title: Electric power supply management system
Inventor: LIBERMAN ISIDOR
IPC: H04L45/02
Filed: 1997-12-03
Abstract: A communication protocol, designed for centralized power line networks, provides a solution for: automatic network mapping and adaptive routing, for automatic log-on of remote nodes and also for optimization of communication routes and control of the traffic volume. A Central Unit (CU) permanent polls all the known Remote Nodes (RN) and a polled RN replies with a message. A new Remote Node (RN), which hears any polling command from the CU, transmits a Burst Log-On Message direct to the CU. A new RN, which hears a reply of polled RN, but not the polling message itself, transmits a Burst Log-On Message, using the replying RN as a relay. There may be a route of several relays between the new RN and the CU and all of them are registered in the Log On message itself. When the CU receives the message from the new RN, it performs a log on of the RN, stores its route, and starts to poll it. This process continues all the time, enabling an addition of new nodes. RN with no communication behaves as a new one and creates a new route, when the previous is no more available. A permanent improving of the existing routes is achieved by using a special field in a message, that indicates the time the message has already traveled via the network. This field is incremented by each relay on the route, and further used by each RN, which hears the message, to improve its route to the CU. The criteria used by RN is the less the time - the better the route. For data, such as a power demand, which is a function of time and should cover all the day, the quantity of data depends on the resolution in use. The system always tries to achieve the highest possible resolution, but if the collection cycle is too long, and the transmitted data doesn't cover the required period of time, the resolution and the quantity of data are automatically reduced to provide a continuous coverage of time.

Title: Process for encapsulating glass fiber insulation
Inventor: ROBBINS HAL J
IPC: B32B3/04
Filed: 1996-08-21
Abstract: Encapsulated glass fiber insulation is made by forming an encapsulating or covering material (152) over the top surface of a glass fiber mat or core (11) with the formed covering material extending adjacent the side surfaces.

Patent CA-2233589-A1 (CA)
Inventor: LEBENS GARY A
IPC: G01N21/88
Filed: 1996-09-16
Abstract: The present invention takes advantage of the efficiency of high-brightness red, infrared, or other color LEDs arranged in a single row, the properties inherent to a focusing element such as a cylindrical lens, as well as the advantages of having a straight-edged diaphragm and light-absorbing enclosure to produce an illumination source for machine-vision systems. The illumination source exhibits multi-diretional properties on one side of an imaginary plane defined by the positions of the row of LEDs, the straight-edged diaphragm, and the focusing element, and minimize light cast on the other side of the plane.  The present invention provides a compact light line generator which has no shadowing or secondary lines. The present invention also provides a method for measuring the height of a raised surface. The present invention provides a method and apparatus which provide an illumination source for illuminating an object in a machine-vision system, and includes a light source emitting light from a plurality of points, the points being on a straight line, a focusing element, the focusing element focusing light from the light source in one dimension to a focal line, wherein the focusing element is separated from the straight line by a distance sufficient to focus rays from the plurality of points into the focal line, and wherein there is a light path from the straight line to the focusing element and then to the focal line, and a first diaphragm located in the light path and defining a sharp edge in the rays.  This embodiment provides a light which has a sharply defined virtual surface which separates lighted areas from areas not lit, and within the lighted areas, provides light from multiple directions to reduce shadowing.

Abstract: An apparatus  equipped with a battery,  such  as  an electrical toothbrush, receives from a charging device a charging voltage which adapts to the charged condition of the   battery   and   on   whose   over-discharging    is correspondingly  small.  On  the  one  hand  the  apparatus comprises a series circuit between a capacitor and a diode which is connected to the charging device parallel to the battery,  wherein  the  diode  is  arranged  in  the  forward direction.  On the other hand in  series  to  the battery there is arranged an electronic switch which periodically for a short time interrupts the charging procedure of the battery.  In  each case  during  such  an  interruption  the charging apparatus is unloaded and its voltage increases jump-like by which means the capacitor can be charged via the diode.  In each case with a closed switch,  i.e. on loading  the  charging  apparatus  by  the  battery,   the capacitor  supplies  a  further  relatively  high  impedance load  so  that  this  independently of  the  value  of  the charging voltage may be supplied with a sufficiently high and constant voltage.

Title: Wave propulsion device
Inventor: MANCUSO ROBERT BRIAN
IPC: A01K85/18
Filed: 1998-09-04
Abstract: An externally powered propulsion device particularity designed to propel floating and submerged water craft, as well as any other vehicles (land or air). The device utilizes a helical coil drive mechanism which causes a flexible body plate(s) to move and undulate in such a way that a travelling unilineal wave motion is produced. The resulting wave creates thrust within any fluidic medium. (See attached description for more detailed information.) In brief, the device is designed to transform mechanical standing wave motion into a travelling wave pattern applicable as a propulsion mechanism.      The device is also broadly applicable in many situations where a travelling wave pattern may be desirable for reasons not related to vehicular propulsion (e.g., pumps, fans, fishing lures, massaging devices, conveyers, amusement devices, etc.).
