Title: Call waiting arrangement
Inventor: TOY LIANE C
IPC: H04M3/48
Filed: 1988-12-13
Granted: 1992-12-15
Abstract: IMPROVED CALL WAITING ARRANGEMENT     Abstract An improved call waiting arrangement where a caller is free to exercise discretion in interrupting ongoing telephone calls because the caller is prompted, for example via an audible announcement, that the called party is busyon another call but that the caller may request interruption of the call by remaining off-hook. If the caller believes that his call is sufficiently important, he requests call interruption by remaining off-hook. If the caller chooses not to interrupt, he may make subsequent call attempts promptly because he knows that the called party is busy on another call rather than being away from home. Alternatively, the caller may activate auto-callback such that a call is completed between the two parties as soon as the status of the called station returns to on-hook.

Title: Method of and circuit arrangement for recovering a bit clock from a received digital communication signal
Inventor: PAUER DIETER
IPC: H03L7/099
Filed: 1989-06-02
Granted: 1992-10-06
Abstract: Abstract Method of and Circuit Arrangement for Recovering a Bit Clock from a Received Digital Communication Signal To recover such a bit clock, a local bit clock having the fre-quency of the signal to be received is generated at the receiving end by means of a clock generator (TG) and a counter (Z). A phase evaluation logic (PAL) evaluates the time position of the leading edge of a received pulse in comparison with a predetermined time position of the effective pulse edge of the local bit clock.      In the synchronous case, the effective pulse edge is located at the center of the received pulse (center-of-bit sampling). Because of nonideal line properties, the duration of the received pulses may differ from the de-sired value. To be able to distinguish a momentary edge drift of a received pulse (pulse too short or too long) from an actual phase shift, the time positions of the leading and trailing edges of each pulse are determined.     If a pulse is too short or too long but symmetrical with respect to the predetermined time position of the effective pulse edge of the local bit clock, this indicates a momentary edge drift, so that no phase cor-rection is necessary.

Abstract: Abstract of the Disclosure There  is disclosed apparatus  for transporting a sample of body fluid such as blood from a first location to a remote  test  site  location.    The  apparatus  operates  in conjunction with a fluid manifold module which has a first sample input port, a second washing fluid input port and a third input port for receiving air.  There are tubing means coupled to said first, second and third input ports which are coupled together and coupled to a sample output line which extends from the first location to the remote location.  The manifold   means contains check valves with one valve for blood and one valve for washing fluid and a diaphragm pump for air.  There are logic means which selectively operate the valves and pump to allow the sample line to receive a sample separated by air barriers from washing fluid solution.   In this manner, a predetermined volume of sample is transported from the first location to the remote test site location.  At the test site location, the presence of sample is detected by detection means and the sample is directed to a test site. The remainder of materials such as the washing fluid and air are discharged at the remote location.   The system includes flexible tubing and the fluids as present are pumped from the first  location  to  the  remote  location  by  means  of  a peristaltic pump or other pump in direct contact with the tubing.

Abstract: ABSTRACT OF DISCLOSURE      A  technique  for  modifying  an  input  rotation  in continuously variable increments to produce a controlled rotational output is disclosed herein.   This technique combines epicyclic motion of a series of planetary shafts in a parallel fashion in order to produce continuous, controlled, intermediate output in the same direction and at the  same speed or a greater speed than the  input rotation.   This intermediate output is then modified to produce a continuous, controlled, final rotational output only when the intermediate output is greater in speed than the input.   The final output can be in the same direction as the rotational input and at a speed which is proportionate to the excess speed of intermediate output.

Abstract: An  alternating  pressure  pad,  useful  between  a mattress  and  a  bed-ridden person  for preventing the occurrence of bed sores, defines between at least two air-impermeable sheets at least two separate sets of inflatable  body  support  chambers  which  interconnect within each set and which are spatially alternated with each  other  in  the  pad.    The  support  chambers  are alternately inflated and deflated out of phase with each other to provide alternating areas on his body where a person lying on the pad is supported by the pad.  In a leg and foot section of the pad, the support chambers in each set extend across the width of the pad and are defined to have a smaller inflated diameter than the other chambers of each set to provide effective support, and freedom from support by them or the mattress, of the heel and ankle areas of the body when those chambers are inflated and not inflated by inflation air applied in a cyclic manner to the  support  chambers  at  a  support pressure at  a  level  consistent with  comfort  of  the person.  A body air chamber is defined in the pad over the support chambers under a pad top sheet which has a predetermined portion of its area open for air to flow through it.   The body air chamber can be supplied with air independently of the support chambers for cooling of the person on the pad as desired without interrupting use  of  the  pad  for  support  of  the  person  in  an alternating pressure relieving manner preventative of bed sores.

Abstract: ABSTRACT OF THE DISCLOSURE           A  method  is  disclosed  for  providing  a  user dependent  status  indication  for  shared  electronic  mail objects within a distributed computing system.  In certain electronic mail  systems multiple  users  are  permitted  to share  access  to  selected  electronic  mail  objects  in  a so-called "affinity" relationship whereby selected end users are permitted to access identical address space within a computer.  Within such systems it is difficult to ascertain a particular status of a selected electronic mail object with certainty due to the fact that multiple users may have access to that electronic mail object.  In accordance with the method of the present invention an attribute list is associated  with  each  electronic  mail  object  which  may contain multiple sets of attributes,  each set associated with a group of recipients, a subgroup of recipients or an individual end user having access to that electronic mail object.   Thereafter,  the activities of each end user are utilized to modify each attribute list associated with that end user.  An end user may then periodically determine and display the status of an individual mail object with regard to the entire group of recipients, a subgroup of recipients or an individual end user.
