Inventor: AHMADI HAMID
IPC: H04J3/16

Abstract: A Medium Access (MAC) Protocol is utilized for wireless radio access for a plurality of remote stations to a base station on a LAN. The MAC protocol is based on a reservation scheme for user data traffic and a random access technique for control and signalling traffic. There is a time division fixed frame structure in which time is slotted, and time slots are grouped into fixed frames consisting of data and control subframes or periods. The fixed frame structure consists of three periods (A, B, and C) along with their respective headers. The first period, the A period, is the outbound channel which is used exclusively for data transfer from the base station to the remote stations. The following period, the B period, is the inbound channel that is used for contention-free data transfer from the remote stations to the base station. The allocation of the data slots in the A and B periods is performed by the base station. The last period of the frame, designated as the C period, is the control channel used for the transmission of reservation requests and data from the remote stations to the base station in a random-access contention mode using a slotted Aloha protocol. The duration of the three periods may be varied using a movable boundary technique. The base station estimates the number of actively transmitting remote stations utilizing feedback information from the remote stations. This estimate is broadcast to the remote stations as control indicia to control their transmission attempts in the C period, thus yielding high transmission efficiency.

Abstract: In the case of casting moulds produced on moulding machines, it is often necessary to integrate into the production cycle separate apparatuses for making a filling hole and vent holes, which have to be made in the upper side of the casting mould located in the cope. The invention specifies an apparatus by means of which both types of hole are made in succession in adjacent working positions of the conveying device. The apparatus requires only a single positioning device, the two types of tool being mounted at different ends of a tool carrier guided on a crossbeam. <IMAGE>

Abstract: A star configuration network system eliminating the need for reassigning addresses to the nodes constituting the system when any of the nodes is removed or relocated. The system comprises a first and a second node, a data processor and a controller. The first node has a plurality of connected terminals and offers a signal switching function. The second node offers a signal transmitting and receiving function and is connected to the first node. The data processor transmits and receives packet data between the first and the second nodes. The controller assigns addresses to all of the connected terminals of the first node. Each of the configured nodes is assigned a predetermined address common to all the nodes. The address of a connected terminal of one node as viewed from a connected terminal of the other node is represented by the address assigned to the connected terminal of that one node and by a connecting relationship between the two connected nodes, whereby the system transmits and receives packets between the two connected terminals.

Abstract: A rotor movement sensing system is provided for use in a postage meter to permit detection of the printing of postage even in the event that power is lost during the printing cycle. A sensor (11) is provided to sense the magnet (10) on a disk (13) when the rotor is substantially past its home position. When the disk magnet (10) passes near a memory element (16), the memory element (16) is magnetized. A Hall-effect sensor is positioned at the memory element (16) so that it provides a signal to the processor (70) indicative of the magnetization of the memory element (16). A solenoidal winding (18) is provided around the memory element (16). The processor (70) has an output which causes a current to flow through the winding (18), whereby the memory element (16) is demagnetized. A flip-flop provides a bistable latch backed up by a lithium cell, and the output of the flip-flop provides a datum for the processor (70).

Abstract: A system and method for virtually reducing interprocess communication packet size by dynamically redispatching packets for execution. A subcommand dispatching process (230) dispatches individual subcommands and accumulates the resources used by each. The accumulated resource value is tested against a threshold. If the threshold is exceeded, the next subcommand position is recorded and control returned to the interprocess communication packet dispatcher for later dispatch. The virtual reduction of the packet size to conform to resource limits processor commitment to a single packet.

IPC: G06F9/48

Abstract: An interrupt mechanism within a data processing system where every expected interrupt has a unique interrupt signature. This interrupt signature is known by the system interrupt handler of the interrupt's particular type, such as external, timer, divide by zero, etc. For example, external interrupt is one type of interrupt, and the FLIH of external interrupt must know the signatures of all expected external interrupts. Every expected interrupt has its signature stored in a plurality of processor general purpose registers. The name of these registers must be known by the interrupt handler that will handle the interrupt. The interrupt handler preserves the processor state when it tries to verify signatures. If a signature match is found, the interrupt handler will branch to the corresponding second level interrupt handler for normal interrupt processing. If the second level interrupt handler is shared by some sources, then the second level interrupt handler must query these sources for the ownership. The lack of an ownership causes the second level interrupt handler to declare the interrupt as spurious. If there is only one source, the second level interrupt handler will handle the interrupt. If an ownership is found among the sources, the routine that was called to establish its ownership will have handled the interrupt properly. A first level interrupt handler will consider an interrupt as spurious after it has failed verifying the signatures of all expected interrupts of its own type.

The distance between a plurality of points on the edge, which are distributed along this direction, and a predetermined reference position chosen along the beam is measured. The predetermined direction is preferably a diameter of the edge of the coil. The optical beam is advantageously parallel to the axis of the coil, and at least two distance measurements are carried out on the edge of each turn of the coil. The detector is preferably installed under the conveyor for transporting the coils, and in the axis of the latter, so as to scan the edge along a diameter. <IMAGE>

Abstract: A method of performing stabilized overwriteable optical recording, wherein overwriting is performed sufficiently even when erasure becomes poor when the low level laser beam intensity P L  is set too low. The low level of recording laser beam intensity is set by playing back a test recording region by illuminating magnetization reversal areas after magnetization reversal areas have been formed in test regions of an overwriteable optical recording medium. Further, an erasure factor is found from the playback signal. In a second embodiment of a method of setting the recording laser beam intensity in order to perform recording on an overwriteable optical recording medium, before a test recording is performed, magnetization reversal areas are formed in a test recording region. These magnetization reversal areas are not erased, and a test recording is performed in this region by overwriting.
