Title: Supervised personnel monitoring system
Inventor: HOCHSTEIN PETER A
IPC: G08B3/10
Filed: 1993-08-30
Abstract: SUPERVISED PERSONNEL MONITORING SYSTEM            ABSTRACT OF THE DISCLOSURE           The monitoring assembly (10) monitors the location of mobile objects (12), i.e., personnel, within a structure (18).  The object (12) carries a transponder  (14)  which periodically transmits status  signals  and  receives  command  signals relating to audio control.  Transceivers (16) are fixed at locations about the structure (18)  for receiving the status signal producing the location signals,   and  transmitting  commands  to  the transponders.    The transmissions  and reception occur during prescribed time windows.  A controller (20)  is connected to each transceiver  (16)  and monitors the location of transponders  (14)  and communication therethrough.  The transponders (14) have audio capability of producing audio messages directly to the person thereof.

Title: High Resolution Acoustic Pulse-Echo Ranging System
Inventor: PANTON STANLEY
IPC: G01S7/524
Filed: 1993-10-13
Abstract: The  uncertainty  inherent  in  high-resolution acoustic pulse-echo distance measuring systems which depend on threshold detection is overcome by transmitting a multi-cycle shot of acoustic energy having a sharply peaked amplitude profile, and locating the peak amplitude of a received echo.  The peaked amplitude is achieved by timing the duration of energization of a transducer producing the shot  so  that  energization  is  terminated  before  the amplitude of oscillation of the transducer has reached a maximum.  This produces a shot which has a definite largest cycle,  which should  in turn produce an echo having a definite largest cycle.

Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with simple surfactants and hydrophilizing agent salts. Thus, a surfactant-containing foam is treated with a solution of, for example, calcium chloride, and is dried to leave a substantially uniformly distributed residue of hydrated or hydratable calcium chloride on the surfactant-containing internal foam surfaces. In-use, the combination of surfactant and calcium chloride hydrate provides a hydrophilic surface to the foam. Other hydratable calcium or magnesium salts such as magnesium chloride can be used. The resulting hydrophilized foams are suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.

Abstract: ABSTRACT OF THE DISCLOSURE A method for tracking information comprises the steps of collecting a plurality of "free" press media information  and  then  selecting  clips  from  this information which relate to a desired client.  The clips are then reviewed and rated as either positive, neutral or negative.  At least one media market definition area for the clip is determined and category information is obtained from the clip.   The associated client, the rating,  the  media  market  definition  area  and  the category information for the selected clip can be placed into a client file in a database.  A client can then be selected and data from the database compiled for each selected clip which is associated with the selected client and one or more selected areas of dominant influence.   The rating totals can be tallied and the tallies as well as other information can be reported to the client.  The media information which is input comes from  print  and  electronic  sources  and  includes editorials, news stories, columns and letters to the editor,  interviews  on  entertainment  shows,  radio interviews, etc.  This media information is considered "free" press or earned press.  The instant method allows the client to track this "free" press in a particular media market definition area and to thereby compare it with their sales, marketing, grass roots, merchandising and/or advertising strategies.

Abstract: ABSTRACT A seal assembly (21) is disclosed for use with a housing (H) which defines a fluid chamber (C) and a threaded opening (O). In threaded engagement with the opening is a threaded portion (13) of a device such as a sensor assembly (11). The housing defines a counterbore (CB) disposed axially between the threaded opening (O) and an external surface (S). The seal assembly (21) includes a metalsupport member (23) including a cylindrical portion (27) having inner (33) and outer (35) portions of elastomeric sealing material. The seal assembly is pressed into the counterbore and, by means of the interference fit therebetween, may be permanently retained therein. As the member is threaded into the opening, the underside (16) of the head (15) deforms a sealing lip (39) radially inward into engagement with the threaded portion (13). As a result, the threaded member may be removed and replaced by another, without loss of sealing function, and without the need to replace the conventional, prior art O-ring seal which would normally be retained on the threaded member.
