Abstract: Collision avoidance is maximized by placing collision avoidance scheduling in a central access manager. The central access manager coordinates downlink transmissions of a base site with the uplink transmissions by subscriber units, virtually avoiding collisions of the two types of transmissions. The subscriber units utilize a waiting period (204, 206) prior to transmission of packets to permit the central access manager to maintain the scheduling.

Abstract: A pivot block for use in a windshield wiper apparatus is described. The pivot block comprises a first member for attachment to a windshield wiper arm and a second member for attachment to a windshield wiper blade. The first member and the second member are connected by a pivot arm arranged such that the second member pivots relative to the first member. The second member includes shoulders that contact the first member, thereby limiting the range of pivoting motion. In operation, the pivot block promotes tilting of the windshield wiper blade when the windshield wiper arm completes movement in one direction. This in turn orients the windshield wiper blade to clean the windshield as the windshield wiper arm moves in the opposite direction. As a consequence, the windshield wiper blade runs smoothly across the windshield during the windshield wiping process without skipping or jumping regardless of the direction in which the windshield wiper arm is moving.

Abstract: Various embodiments of a wiper assembly are disclosed which facilitate the removal or shattering of ice or snow debris lodged and trapped beneath a wiper blade during its movement. Embodiments of the invention are disclosed which provide means to overcome normal urging forces of the wiper arm in a direction towards a light transmitting screen member and to urge the wiper arm of the wiper assembly away from the surface of the screen member. Some structures according to the invention may cause the wiper blade to return with an impact force sufficient to break ice and snow debris trapped beneath the wiper blade and also possibly frozen to it. Other embodiments include means for imparting vibrational movement to the wiper assembly to release or shatter ice and snow trapped beneath the blade or frozen to it.

Abstract: A chiropractic mallet instrument for delivering a selected impact to the spinal vertebrae and or other bones of a patient in order to remove a vertebral subluxation and/or other subluxations includes a tubular housing with a central handle movably supported thereon, a compression spring engaging a latch assembly and an elongate anvil member coaxially and movably fitted within an interior of the housing and extending from one end thereof, the anvil member including a distal end zone with a distal tip structured for removable attachment of various impact heads of different sizes, shapes and densities, the anvil member being axially movable relative to a longitudinal axis of the housing between a retracted,  cocked position and an extended, released position.  The latch assembly is operably interconnected to the central handle and carries and holds the anvil member in the retracted, cocked position upon movement of the central handle towards a palm handle on an opposite end of the housing.  Application of pressure to the distal tip actuates a trigger mechanism, releasing the latch assembly and anvil member, causing the compression spring to urge the anvil member rapidly to the extended, released position.   A guide element is selectively positionable within one of three directional grooves in the distal end zone to control rotation of the anvil member when moving to the extended, released position, so that the impact head delivers either a straight axial force or a clockwise or counter clockwise torsional force on impact.

Title: Apparatus and method for mitigating excess time delay in a wireless communication system
Inventor: SPEAR STEPHEN L
IPC: H04B7/26
Filed: 1996-12-13
Granted: 2001-06-19
Abstract: A wireless communication system (200, 300, 400, 500) mitigates the effects of excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so that the cumulative time delay at a transition cell (209, 325, 331) is reduced. In another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403-407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverage area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.

Granted: 1999-08-03
Abstract: In a cordless telephone apparatus including a base unit and a sub unit connected with each other by wireless, the base unit has a memory for storing therein telephone number data which are referred to from the sub unit.  When the base unit is busy, the transfer of a calling signal between the sub and base units is not performed.  The access from the sub unit to the memory of the base unit is always permitted.   The memory includes a callers area in which the telephone numbers  of callers of received calls and the reception times of the calls are stored and a directory area  in which  frequently  called  telephone numbers and the number of placing calls of the numbers are stored.  The telephone numbers in the callers area are retrieved based on the reception times.   The telephone numbers in the directory area are retrieved based on the numbers of placing calls.  By adding the number of placing calls of the telephone number stored in the callers area to the number of placing calls of the telephone number stored in the directory area, the telephone  number  retrieval  from  the  directory  area  functions correctly.  Moreover, by using the cordless telephone apparatus as a terminal apparatus of a private telephone system,  data stored in a main apparatus of the system are referred to from the sub unit of the terminal apparatus.

Abstract: The transducer supply is configured for supplying a passive transducer arranged in an explosion-hazard zone with electrical energy from a DC voltage source.  The electrical  energy  is  transmitted  via  a  two-wire connection,  via which in the opposite direction the measured value sensed by the transducer is transmitted by the transducer setting the direct current obtained from the DC voltage source to a value variable between two  limit  values.  As  a  means  of  protection  a transformer  is  inserted  in  the  two-wire  connection which affects  DC  decoupling.  The  direct  current  is chopped  in  accordance  with  the  principle  of  a  DC voltage  converter  at  the  primary  side  of   the transformer and re-rectified on the secondary side. To permit connection of an active transducer instead of a passive transducer,  the active transducer having its own  energy  supply  and  furnishing  at  its  output connections a direct current in a quantity representing the measured value,  an adapter circuit controlled by the output current of the active transducer is inserted between the output connections of the rectifier circuit and the connecting terminals provided for connecting the active transducer, this adapter circuit loading the rectifier  circuit  with  a  direct  current  which  is proportional  to  the  output  current  of  the  active transducer.
