The presses each contain circuitry defining a signal and control path for the press and a plurality of electrical contacts that renders the path accessible and facilitates serial connection of the presses without disruption of the path.  At least one of the presses includes a port for receiving connection to a controller, which thereby engages the signal path and, via the path, operates the presses independently or together as appropriate.  The system includes a connector that is used to couple the electrical contacts of one press to those of the second press, thereby establishing a single, continuous signal and control path through both presses accessible to the controller.  The system can accommodate a perfecting assembly that may be selectably engaged between the presses, and which thereby becomes a part of the system.  The perfecting assembly includes circuitry defining a signal and control path for the assembly and sets of of electrical contacts capable of mating with the contacts of two presses and retaining the continuous path.

Abstract: The tracking of mobile terminals served by base stations supported by respective switches formed into respective peer groups of switches in which the peer groups are then formed into a hierarchical logical network having a prescribed number of levels of scope S, and in which individual ones of the switches serve as a home switch for respective ones of said wireless terminals is enhanced. Specifically, responsive to receiving a registration message sent by one of the wireless terminals, the receiving switch notifies the home switch associated with the sending terminal.  The home switch, in turn, notes the current location of that terminal and sends a similar message to the switch serving the zone in which the sending wireless terminal was last located.  The latter switch, responsive to receipt of the message sets a pointer that points to (a) the current location of the sending wireless terminal if the switch is within the scope of the current location of the sending terminal or (b) the home switch if the switch is outside of the scope of the current location of the sending terminal.

Abstract: The image rendering system (20) of the present invention rapidly renders graphical image of complex structures. A complex structure is represented by a plurality of objects that can be organized into an object hierarchy. The image rendering system (20) projects a plurality of rays (55) from a given vision coordinate. For each projected ray, the image rendering system (20) determines which objects in the object hierarchy are intersected by the ray (55). The image rendering system (20) then determines which object among those intersected by the ray (55) is closest to the given vision coordinate and adds that object to a set of visible objects. As objects are added to the set of visible objects, each object is rendered on the display in accordance with a current vision coordinate. Since the process of adding objects to the set of visible objects is decoupled and run asynchronously from the process of rendering visible objects on the display, the image rendering system (20) is capable of rendering objects at real-time frame rates.

Abstract: An intelligent charge alternator is disclosed and is adapted to operate with two or more batteries which are individually charged, alone or connected in series. In each stator slot there are 2, 3, 4, etc., windings in parallel and each coil is independent to the other. It requires a rectifier bridge for each coil in parallel, either star, triangle, diphase, or single-phase winding and can be connected in series. The batteries can also be connected individually or in series between negative positive negative pole, etc., adding in this case the voltages, but it will charge the discharged battery in amperes and it will not charge the charged battery with over potential.

Abstract: A very compact tankless heater delivers heat in proportion to demand. A flow responsive valve energizing an electrical control system is purely flow responsive, even to minute flow, and consumes no power when dormant. An uncomplicated electronic control system is connected to power by the flow switch, and is substantially deenergized when dormant. Most electronic components of the control system are mounted on the flat front wall of the pressure vessel. Thus, overall dimensions are minimized, cool water serves as a heat sink, and heat generated by electronic controls is captured for heating purposes. In particular, triacs controlling the heating elements are cooled, thus prolonging their life. A preferred embodiment of the novel heater has a maximum electrical consumption of 22 kilowatts, with equivalent heat output, and has overall external dimensions of 24 in height, 5.5 inches in width, and 4 inches in depth (61 cm in height, 14 cm in width, and 10 cm in depth). An outlet pipe fitting extending above adds approximately 2 inches (5 cm) to the overall height, enabling the water heater to be installed in a typical building interior wall of partition.

Granted: 2005-12-13
Abstract: An engine kill switch system (10) has a transmitter (12) and receiver (14) which are linked through specific transmitted codes within a frequency. The receiver (14) is mounted directly on the boat and wired to an engine kill switch (10), maintaining the switch (10) in the closed position as long as a signal is received from all of the activated transmitters (12). Once the transmitter signal is unintentionally deactivated, the receiver (14) shuts down the engine. A range adjustment (20) allows the separation distance between the transmitter (12) and receiver (14) to be changed, dependent upon the size of the boat and end use. A strobe and audio warning (22) can also be attached to the receiver (14) and activated simultaneously with the deactivation of the engine. The transmitter (12) has a programmed unique code recognized by the receiver (14). The system (10) can also be used as an antitheft device simply by removal of one transmitter (12), thereby rendering the engine inoperable.

Abstract: The present invention relates to a method and an apparatus for filtering an electric current supplied to a motor (M). A current supplied from a frequency transformer means (4) provided with a voltage source circuit to the motor (M) is conducted through a coil means (L) between the frequency transformer means (4) and the motor (M) for preventing any essential rapid increases of the current. The reactive current portion of the motor (M) is compensated by a condenser means (C) arranged between the frequency transformer means (4) provided with the voltage source circuit and the motor (M). By means of the inventive filter the reactive current of the motor (M) is essentially compensated and the power ratio thereof is increased.
