Title: Audience monitoring system
Inventor: LURIE OSCAR M
IPC: H04N17/00
Filed: 1987-06-25
Granted: 1993-11-23
Abstract: ABSTRACT OF THE DISCLOSURE        Each doorway or passageway between rooms in which a device may be located is fitted with another device which detects motion and the direction of the motion through the passage.  Each room is equipped with a signal emitter that is controlled by the motion detector at the room's passage.  The signal emitted by the signal emitter is received by a monitor which monitors the status of the device which happens to be located in that room.  The emitted signal informs the monitor when there has been motion into the room (audience increase) or when there has been motion out of the room (audience decrease).  Motion between rooms will result in a decrease signal being sent by the signal emitter in one room and an increase signal being sent by the signal emitter in the other room.  If no device and monitor are located in a room, the increase or decrease signal is ignored by the audience monitoring system.  If a monitor is located in the room, however, the increase or decrease signal received by it from the signal emitter will cause the monitor to issue an immediate prompt, to remind the persons in the room to push the keys of an inputting device to report the identity of the individuals who must entered or departed.  The monitor will record this information, the time of day, and information received from the inputting device, such as channel selection and the like in the case of a television.  The present invention may also be connected to a distributed monitoring system which monitors each device and each passageway in the house equipped with the motion detector of the present invention.

Granted: 1992-08-04
Abstract: (092A/2) "Display Radio Pager Having Graphic Alarm for Selective Indication of Memory Availability Factors"   ABSTRACT OF THE DISCLOSURE         A selective calling display radio pager has a memory which is configured to store a plurality of received messages for later retrieval so that the amount of messages which can be stored is limited by one of first and second memory availability factors depending on the length of each of the received messages.  A controller determines one of the first and second memory availability factors which is more accurate early warning against possible depletion of the memory than the other and displays it on a graphic alarm indicator along with a display of a message retrieved from the memory. Specifically, the controller determines the ratio of a sum of messages which can be received at a given time to the maximum number of messages which can be stored and the ratio of a sum of message segments which can be received at said given time to the maximum number of such message segments-which can be stored, and provides a display of the smaller ratio on the graphic alarm indicator.

Title: Coin handling system
Inventor: CROSSMAN THOMAS
IPC: G07F1/04
Filed: 1987-10-15
Granted: 1991-11-05
Abstract: ABSTRACT                      COIN HANDLING SYSTEM     The coin handling system prevents coin to coin contact taking place in coin operated equipment.  This is achieved by an arrangement whereby the presence of a coin activates a lever which then prevents a subsequent coin touching the previous one.  A series of such levers are employed in the coin store of coin operated equipment, the actual number depending upon the number of coins to be stored.  When the first coin is cleared from the store by a suitable gate arrangement, all coins move along the store by one position, the separation being maintained by the interaction of the levers and coins.  The advantages of the system are that a wider range of coins from one coin set can be accommodated in a single store than is presently possible.  The coin insertion sequence is maintained for the purposes of microprocessor control since a single store is used.  Since coins cannot overtake each other the risk of coin jams is lessened.

Granted: 1991-01-22
Abstract: Abstract of the Disclosure Load Responsive System Having Synchronizing Systems Between Positive and Negative Load Compensation A load responsive system is provided with two synchronizing systems for positive and negative load compensation.  One of the synchronizing systems varies the flow through a negative load compensator, during control of a negative load, in response to the inlet pressure of a fluid motor which is controlled by a positive load compensator.  The other synchronizing system isolates the system pump from the fluid motor during control of the negative load while make-up flow to the fluid motor is supplied from the fluid exhaust system.  In a more specific arrangement, the system pump is isolated from the fluid motor through the use of the positive load compensator and totally independent of any negative load compensating action.          The synchronizing systems function in response to an external signal(s), which can be a function of any selected specific parameter of the system.
