Title: Coolant corrosiveness indicator
Inventor: ARGYLE CHARLES S
IPC: G01N27/26
Filed: 1990-04-19
Granted: 1999-11-02
Abstract: A fluid sensor for heat exchanger system includes a supporting device such as a tubular hose fitting for mounting the sensor in the system so that heat exchanging fluid circulated in the system comes into contact with the sensor, A window or sight glass is mounted in or on the supporting device and a visual indicator is visible through the window or sight glass. The visual indicator can be a movable flap. The indicator is movable from first position indicating that the heat exchanging fluid is in a non corrosive state to a second position indicating that the fluid has become corrosive to at least a limited degree and requires replacement or treatment.      A corrodible release mechanism holds the indicator in the first position and is located so as to be immersed in the heat exchange fluid during use of the sensor. The release mechanism corrodes and breaks when the fluid becomes corrosive to at least a limited degree, thereby releasing the indicator so that it moves to the second position.

Abstract: An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a threaded cavity that receives a set screw which is adapted to communicate with the collet to expand and contract the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Tightening of the set screw causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis.

Title: Occupancy sensor and method of operating same
Inventor: WILLIAMS ERROL R
IPC: H05B37/02
Filed: 1996-02-05
Granted: 2001-05-01
Abstract: An occupancy sensor that provides improved performance by the inclusion of a microprocessor that controls the sensing transducers and processes the received signal to optimize desired detection performance. The occupancy sensor includes a quadrature detection technique and automatic sensitivity adjustment that reduce false detection caused by air flow, hallway traffic and other noise sources. A fault detection method executed periodically detects fault conditions in the sensor or sensing area caused by component failure or obstructions in front of the sensor. Transmitter power is varied depending on the size of the desired coverage area. Since various ambient parameters such as line voltage, light level, and temperature may be easily and usefully monitored, the microprocesor may use these variables to make intelligent decisions in controlling electrical loads, such as building lighting and ventilation.

Abstract: An assembly for sensing and/or monitoring the level of a material in a vessel includes a level sensor mounted in the vessel so that it comes into contact with the material when the material has attained a predetermined level.  The  level  sensor  contains  a  low-frequency sensing system and a high-frequency sensing system. The low-frequency sensing system is formed by a mechanical vibrator  system  induced  to  vibrate  at  its  natural resonant  frequency,  and  establishing  whether  the mechanical  vibrator  system  is  in  contact with  the material or not is achieved by evaluating the frequency and/or  amplitude  of  the  mechanical  vibrations.  For forming  the  high-frequency  sensing  system high-frequency elastic vibration is induced in a component of  the  level  sensor,  and  establishing whether  this component is in contact with the material or not is achieved by evaluating an electric signal generated as a function of the high-frequency elastic vibration.

Title: Strengthening the authentication protocol
Inventor: PATEL SARVAR
IPC: H04L9/32
Filed: 1998-09-30
Granted: 2002-03-19
Abstract: The present invention strengthens authentication protocols by making it more difficult for handset impersonators to gain system access using replay attacks. This goal is accomplished using challenge codes as a parameter for determining authentication codes, whereby different challenge codes cause different authentication codes to be generated. In one embodiment, the challenge codes are functions of challenge types (e.g., global or unique challenges) and/or handset states (e.g., call origination, page response, registration, idle, and SSD-A update). This embodiment prevents handset impersonators from successfully utilizing replay attacks to impersonate a legitimate handset if the legitimate handset is in a different state than the handset impersonator, or if the legitimate handset is responding to a different challenge type than the handset impersonator.
