Granted: 1993-05-11
Abstract: WHEELCHAIR ACCESSIBLE WEIGHT TRAINING APPARATUS            ABSTRACT:       An exercise equipment for use by people in wheel-chairs has a stationary frame within which a user can readily locate their wheelchair,  including attachment means for se-curing the lower body of the user to the chair.   A guide frame pivotally secured to the stationary frame is readily adjustable in its angle of inclination, which angle defines the plane of displacement in which weight-lifting exercise is performed by the user.   A load bar is secured to the guide frame,  for displacement therealong by the user, in carrying out their selected exercise.   The load bar is connected by its ends in load transfer relation with two sets of selec-tively adjustable weights.  Use of a load bar in sliding re-lation with a guide frame diminishes the risk of loss of con-trol of the weights.  The equipment may be readily used and adjusted in relation to the angle of lift and the required weight load, by a majority of users, despite significant in-capacitation.

Title: Rf channel expansion in a trunked radio communications system
Inventor: WALDROUP ANTHONY B
IPC: H04W84/08
Filed: 1989-06-01
Granted: 1992-10-27
Abstract: RF CHANNEL EXPANSION IN A TRUNKED RADIO COMMUNICATIONS SYSTEM ABSTRACT In a trunked radio frequency communications system, an arrangement dynamically "expands" or extends the frequency allocation table stored within the "personality" defining non-volatile storage device of transceivers to include additional RF channels. A channel configuration control message specifying a logical channel field and an FCC channel number defining an RF channel frequency is periodically transmitted over the active RF digital control channel. Transceivers correctly receiving this channel configuration message extend their stored frequency allocation tables to add the additional channel entry specified by the message. The transceivers reference these additional records in response to call messages and are thus capable of operating on the new channels. Channel configuration messages are periodically repeated at time intervals long enough to ensure the messages have no real adverse impact on control channel loading but short enough to cause transceivers to almost immediately update stored channel information. Errors are prevented from occurring by transmitting the channel configuration message in both slots of an outbound control channel message and requiring receipt of a non-zero site identification control message before processing any channel configuration message.

Abstract: ABSTRACT OF THE DISCLOSURE         A cassette tape player utilizes a tape cassette having apertures formed through one side wall of its casing to accept a magnetic head and a pinch roller.  The cassette tape player has a body assembly on which the tape cassette is freely loaded or unloaded and a lid supported by the body assembly so as to be freely rotatable for closing and opening the cassette tape player.  The tape cassette is inserted into a loading region of the body assembly by closing the lid.  A head assembly chassis is supported by one side end portion of the cassette loading portion so that it moves together with the lid.  The head assembly also supports a magnetic head holder and the pinch roller.  The tape cassette is supported by securing the upper surface wall of the cassette casing by inserting cassette holding members into the pinch roller insertion openings of the tape cassette.  These holding members which are substantially parallel to the inner top wall of the lid support one side of the upper surface wall of the tape cassette while spring members provide opposing pressure to the opposite side of the upper surface wall of the tape cassette.          The holding member and spring member combination hold the tape cassette for loading in a compact arrangement to ensure efficient use of space in the cassette tape player.

Abstract: An electro-optic welding lens assembly for the use in a welder's helmet or protective eyeshield comprises a filter arrangement with at least one liquid crystal light shutter element and a control unit for changing the transmission rate of the filter assembly in response to ambient light conditions. The light sensing element used to control the transmission of light through the filter arrangement is simultaneously an opto-electric transducer, supplying power to the control unit and the light shutter element. Thereby, there is no need for an additional power supply like a battery. If the sensing and transducer element is arranged behind the light shutter element, a self-regulating loop can be realized to continuously vary the transmission rate of the filter arrangement and thereby to keep the viewing illumination through the lens assembly essentially constant.
