摘要： A transient blocking unit (TBU) includes at least two depletion mode transistors connected to each other such that they can rapidly switch from a normal low-impedance state to a high-impedance current blocking state in response to an over-voltage or over-current condition. This behavior makes TBUs useful for protecting electrical devices and circuit from harmful electrical transients. Some kinds of transistors can exhibit a phenomenon known as current collapse, where channel conductance is temporarily reduced after exposure to high voltage. Although current collapse is undesirable, transistors exhibiting current collapse can have otherwise favorable properties for TBU applications. According to the present invention, a TBU is provided where a diode is placed in parallel with a TBU transistor that can exhibit current collapse. The diode prevents high power dissipation in a current collapsed transistor, thereby reducing the vulnerability of the TBU to permanent damage or destruction in service.

摘要： An animal detection and deterrent system enabling an out of doors area to be protected from intruding animals. A primary laser beam FIG. 1 (1.14) is produced from master laser/sensor (1.10), and precisely forwarded around an area of any configuration and topography via forwarders (1.11), (1.12), (1.13) or FIG. 10 (10.39), (10.40) and (10.41).Master laser/sensor (1.10) and all forwarders, contain mechanisms to accurately adjust the direction of laser beams and position of light sensors. Light sensors contain filters to block ambient light and admit only laser light to allow operation in bright sunlight or darkness.When the system is in a stable “on condition”, the laser beam ultimately strikes light sensor (6.65) in the master sensor (1.20). An animal interrupting the laser beam, at any point in the periphery, prevents laser light to strike light sensor (6.65) in master sensor (1.20). This causes light sensor (6.65) to initiate an electronic signal to an electronic circuit, FIG. 14, and microprocessor (14.102) mounted on circuit board (4.97).Microprocessor (14.102) activates a deterrent system, causing the animal to vacate the area. Various deterrent systems can be employed including jetted water, pressurized air, fans, and gyrating balloon figures.

摘要： An electrical surge protection device (12) confers protection to an output node (13) from electrical surges on a data or power line (10) incident on an input node (11). A transistorised surge protection device (18) is located in a current path between the input node (11) and the output node (13) and is configured to assume an isolating state in response to an over-current therethrough. A voltage-triggered protective circuit comprising a diac (16) in series with a bi-directional zener diode (14) is connected between the output side of the transistorised surge protection device (18) and a surge sinking node (15). The voltage-triggered circuit assumes a low-impedance state in response to an electrical surge at output terminal 13. Consequently a surge current is passed through zener diode (14) and surge diac (16) to the surge sinking node. In response to the surge current the transistorised surge protection device (18) assumes a high impedance configuration thereby isolating output node (13) from input node (11). Since neither the zener diode and diac combination, nor the transistorised surge protection device (18) are subject to sustained surge associated currents, embodiments of the invention can be compactly packaged.

摘要： An apparatus and method for temperature-dependent transient blocking employing a transient blocking unit (TBU) that uses at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device. The interconnection is performed such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device in concert to effectuate their mutual switch off to block the transient. The apparatus has a temperature control unit that is in communication with the TBU and adjusts at least one of the bias voltages Vp, Vn in response to a sensed temperature Ts, thereby enabling the apparatus to also respond to over-temperature. In some embodiments the p-channel device is replaced with a positive temperature coefficient thermistor (PTC). The temperature control unit can use any suitable circuit element, including, among other a PTC, resistor, negative temperature coefficient element, positive temperature coefficient element, transistor, diode.

摘要： An apparatus and method for high-voltage transient blocking employing a transient blocking unit (TBU) that has at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device in concert. Specifically, the bias voltages are altered such that the p-channel device and n-channel device mutually switch off to block the transient. The depletion mode n-channel device employs a set of cascaded low-voltage depletion mode field effect transistors (FETs) such as metal-oxide-silicon field effect transistors (MOSFETs) connected source-to-drain to achieve the desired high-voltage operation of the TBU.

摘要： An improved bi-directional transient blocking unit (TBU) is provided having a dual-gate central transistor. The gates of the central transistor are connected to the rest of the TBU such that high voltages can only appear between a gate and the central transistor terminal further from that gate. In this manner, the total device size required to provide a given breakdown voltage can be significantly reduced compared to a conventional symmetric lateral transistor having a single gates.

摘要： An artificial intelligence design and qualitative modelling tool is disclosed for creating computer models and simulating therein continuous activities, functions and/or behavior using developed discrete event techniquers. Conveniently, the tool is organized in four modules: library design module, model construction module, simulation module, and experimentation and analysis. The library design module supports the building of library knowledge including component classes and elements pertinent to a particular domain of continuous activities, functions and behavior being modelled. The continuous behavior is defined discretely with respect to invocation statements, effect statements and time delays. The functionality of the components is defined in terms of variable cluster instances, independent processes and modes, further defined in terms of mode transition processes and mode dependent processes. Model construction utilizes the hierarchy of libraries and connects them with appropriate relations. The simulation executes a specialized initialization routine and executes events in a manner that includes selective inherency of characteristics through the library hierarchy and runs the events through a time and event schema until the event queue in the simulator is emptied. The experimentation and analysis module supports analysis through the generation of appropriate log files and graphics developments and includes the ability of log file comparisons.
