Abstract: A hierarchical display of protocol layers for communication data. Fields of the communication data are converted into field cells where each field cell has a text field and a field descriptor. The field cells for each protocol layer are arranged by an interpreter into protocol units according to a protocol standard for that layer and then displayed in a hierarchical manner. Detailed specifications for field cells taken directly from the protocol standard can be displayed by using a cursor over the field cell. Indicators in particular ones of the field cells allow certain field cells within a protocol unit to be collapsed or expanded within the protocol unit or allow lower protocol units to be collapsed or expanded into the higher protocol units.

Abstract: A method and apparatus for synchronizing with a network without connecting to the network by shadowing a slave device while a master device connects the slave device to the network. The master device maintains a system clock time. The master and slave devices exchange communication traffic during time slots on channels in a channel hopping sequence derived from the system clock time. The method and apparatus obtain a slave clock time in an inquiry response packet from a slave device when the master and slave devices are not connected in the network and then use the slave clock time for shadowing the slave device for receiving a master page frequency hop synchronization (FHS) packet having the system clock time.

Abstract: A method and apparatus for synchronizing with communication traffic in a BLUETOOTH network without joining the network. The apparatus transmits an inquiry signal and receives an inquiry response signal having a coarse system clock time. The apparatus uses the coarse system clock time for estimating an initial channel in a channel hopping sequence then advances channels through the sequence in steps of four or more for scan window time periods of four or more time slot periods until a communication traffic signal is recognized. The time-of-arrival of the traffic signal is used for refining the coarse system clock time in order to acquire the exact system clock time. The exact system clock time is used by the analyzer for deriving the channels and timing of the sequence for synchronizing to subsequent communication traffic signals.

Abstract: A method and apparatus for synchronizing with communication traffic in a network without joining the network. The method and apparatus synchronize to the communication traffic by mimicking a BLUETOOTH slave device in order to obtain a preliminary or unconnected system clock time in a master page frequency hop synchronization (FHS) packet from a BLUETOOTH master device when the master device is not connected to any BLUETOOTH slave devices, and then updating the preliminary system clock time with a time-of-arrival of a communication traffic packet from the master device after a connection is formed between the master device and a BLUETOOTH slave device.

Abstract: A method of protecting data, stored in a memory device of a computer system connected to a SCSI interface, against, unauthorized access whereby access by the computer system to the memory device is either permitted or refused, depending upon the authorization of a request, by an exchange of information between the computer system and the memory device at the SCSI interface. Authorization is by means of identification of an authorized user. During access by the computer system to the memory device, any kind of operation with the memory device can be blocked, or access permission given for memory readout only, or for readout and recording, or only for recording. The equipment for carrying out the method includes a memory device connected by a SCSI bus to a host computer system, while between the memory device and the host computer system there an additional control unit with authorization block is inserted.

Abstract: A memory chip having a system for controlling sensing time of a data sense amplifier (DSA). A global control is adapted for initiating data access to the memory blocks. A wire path coupling the global control to each memory block is utilized by each memory block as a part of transmitting path for receiving a block enable signal sent from the global control. Specifically, a memory block includes a wired-NOR circuit adapted to send a DSA enable signal to the DSA in response to being selected by a block enable signal. In contrast to a simple delay circuit that only controls the DSA roughly, this wired-NOR circuit tracks internal read signal, and controls the DSA tightly. The time from the activation of the block enable signal by the global control to the enabling of the DSA stays approximately the same irrespective of the memory block's location in the memory chip. Block location independence of DSA sensing time allows tighter memory cycle.

Abstract: A method is provided for retrofitting an existing dead-bolt assembly with an electrically operated actuator (12, 112, 212, 312, 800). The electrically operated actuator automatically operates the dead-bolt assembly while preserving manual operation of the lock. The actuator assembly has rotating means for rotation of the drive bar (18), which in turn extends or retracts the bolt (14) of the lock. The rotating means may be a lever (28, 128, 238, 328, 438, 818) attached to the drive bar (18) that is pivotable about the axis of rotation of the drive bar (18). The actuator assembly has driving means that forces the rotating means to rotate. The driving means is responsive to an electrical signal, which, for example, may be initiated from a remote-controlled transmitter (502, 602). The driving means may include a motor (20, 120, 220) for rotating a rod (22, 122, 222, 322) that in turn operates an assembly that rotates or drives the rotating means.

Abstract: DRAM with column slices improves circuit redundancy. Slices have global column length, and memory is divided in groups with size of redundancy columns having slices. Failure detected among slices of corresponding storage is replaced by corresponding redundancy column slice, such that column redundancy division is in vertical column direction. Column includes global data line shared by column slices and multiple blocks. Redundant column is added to memory array, and redundant control circuits or comparator are proximate to data sense amplifiers. Defective column address are provided to controller through non-volatile memory, or laser-blown or electrically-programmable fuses. When column address is presented, incoming address is compared with stored address, such that select data is output on redundant data line when equal addresses (i.e., hit detect), or normal data is output when unequal addresses (i.e., "miss" detected).

Abstract: A zone cabling termination cabinet of fire-resistant metal, provides a non-plenum enclosed space, close to the work station it serves, recessed into the plenum above a suspended ceiling, for housing communications cable connections and switching, without the need to use high-cost plenum fire-rated materials. The cabinet has an equipment mounting plate removably mounted on the interior surface of an access door, which when closed is flush with the bottom wall of the cabinet, which in turn is flush with the suspended false ceiling. The exposed lower surface of the door is clad with fire resistant ceiling tile material, the utility thereof being two-fold: the cladding makes the cabinet more fire resistant, and visually it blends with the rest of the ceiling, is inconspicuous and not readily detected by the unsuspecting eye, thus providing some measure of security from unauthorized meddling.
