| A mobile high voltage network supplies electrical consumer units connected via a plug-in connector and can be switched on and off by means of mechanical switches, with a fuse responding in the event of a short circuit. The high voltage network carries a direct voltage and to each electrical consumer unit (8; 10) a separate diagnostic and protection monitoring system is assigned which is activated when it is switched on and/or off. Such a direct voltage and high voltage network in conjunction with the diagnostic and protection monitoring system makes it possible, before starting up any circuit of consumer units, to effect a self-diagnosis of the protection monitoring system, to ensure that all components are fully functional. Without this, self-diagnosis with proof of functionality the relevant circuit of consumer units is not switched on. | ||||||
| 144 | Power delay device | US11145245 | 2005-08-15 | US20070035905A1 | 2007-02-15 | Charles Kessler |
| The concept of the Power Delay Device began as I was working at my computer. There was a power failure lasting several minutes and when the power tried to come back on, it was erratic. After several attempts the power stayed on. I was concerned about the negative effect of the surges on the electronics in the computer. Even though the computer was using a surge suppressor, I do not trust their effectiveness. I thought that there must be a more thorough device and that is when I built a Power Delay Device. It works beautifully. | ||||||
| 145 | Process for managing the current-surge that occurs when electric service is restored, following a power outage | US11271761 | 2005-11-10 | US20060245134A1 | 2006-11-02 | Max Gratzl |
| A process for managing the current-surge that occurs when electric service is restored, following a power outage. In the initial embodiment, the device takes the form of a kit of, typically, six modules (Figure Two). The user inserts a module between the power plug of the appliance and the wall outlet. The modules insert a time-delay between the arrival of electric power at the wall, and delivery of that power to the affected appliance. The user selects from a choice of delays ranging from ten seconds to 100 seconds, in ten-second steps. Thus, the startups of affected appliances are sequenced such that the current-surges are distributed over ten-second intervals. No two or more delays should be the same, and simultaneous startups leading to combined current-surges are avoided, leading to aforementioned benefits. | ||||||
| 146 | Electrical safety lockout mechanism for power tools and other hazardous machinery | US10342001 | 2003-01-14 | US07075195B2 | 2006-07-11 | Thomas E. Feil |
| An improved electrical lockout mechanism includes a first connection means to a power source, and a second connection means to a power input terminal of the machine being protected. The machine includes a manually-operated ON/OFF switch. A switching element, which is coupled between the first and second connection means, selectively completes and breaks an electrical circuit between the first and second connection means in response to a control signal supplied thereto. A control circuit generates this control signal in a manner that prevents unwanted machine restarts. The switching element may be realized by an electromagnetic relay device, or by a thyristor-based switching device such as a triac device. The electrical lockout mechanism can be integrated with a power cord that delivers electrical power to a machine, or can be integrated into the machine itself. | ||||||

| 148 | Method and system for sensing switch position to prevent inadvertent startup of a motor | US10696449 | 2003-10-29 | US20040155529A1 | 2004-08-12 | Daniele C. Brotto |
| A method for preventing sudden inadvertent operation of a motor of a tool or appliance when the motor is initially electrically connected to a power source while an On/Off switch for controlling the motor is in a closed (i.e. nullOnnull) position. The method includes electrically connecting the motor to a power source and determining a position of the On/Off switch when the motor is initially electrically connected to the power source. The position of the On/Off switch is determined by either sensing whether current is flowing through the motor or voltage is present at the motor when the motor is initially connected to the power source. | ||||||

| An electronic device does not carry out control operation corresponding to a signal from an operation button which is kept in pressed state when electric power is supplied. When electric power is supplied, the voltage changing depending on open and closed state of switches SW1 to SW4 corresponding to operation buttons to be manipulated is judged to be a specified value or not. When the voltage is not judged to be specified value, the control unit does not carry out control operation corresponding to the signal from the operation button that has been in pressed state. | ||||||

| A monitoring device for an electrical machining tool, in particular for temperature monitoring with an accumulator-driven machine, includes a switch element (12) for separating an electrical consumer (14) from a current supply device (10).

Furthermore, the present invention relates to an electrical machining tool as well as a current supply device with the inventive monitoring device and a corresponding method of operation. | ||||||

| An improved electrical lockout mechanism includes a first connection means to a power source, and a second connection means to the power input terminal of the machine being protected. The machine being protected includes a manually-operated ON/OFF switch. A switching element is operably coupled between the first and second connection means. The switching element is adapted to selectively complete and break an electrical circuit between the first and second connection means in response to a control signal supplied thereto. A control circuit generates a control signal that is supplied to the switching element thereby causing the switching element to complete the electrical circuit between the first and second connection means under a first set of operating conditions and causing the switching element to break the electrical circuit between the first and second connection means under a second set of operating conditions in a manner that prevents unwanted machine restarts. The switching element may be realized by an electromagnetic relay device, or by a thyristor-based switching device such as a triac device. The electrical lockout mechanism can be integrated with a power cord that delivers electrical power to a machine, or can be integrated into the machine itself. | ||||||

| Intelligent power supplies to provide power to electronic devices in a manner the avoids causing a power supply circuit fuse to blow or breaker to trip are disclosed. The power supply circuit includes a power supply control device that determines whether supplying power to an additional electronic device would exceed the capacity of the circuit and cause the fuse to blow or the breaker to trip. The power supply control device communicates with electronic devices via a power control interface to determine the power requirements of the electronic devices. Power is supplied to the devices that can be supplied without causing the fuse to blow or the breaker to trip. Power is not supplied to the devices that would cause the fuse to blow or the breaker to trip. | ||||||
| 154 | Turn-on control circuit for electric devices | US69283 | 1993-05-28 | US5535082A | 1996-07-09 | Edoardo Botti; Andrea Fassina |
| A turn-on control circuit having a comparator supplied with a turn-on voltage increasing gradually during the turn-on phase of a device for protection. When the control voltage reaches a predetermined value, the comparator supplies a diagnostic enabling signal to a diagnostic stage, which, in the event an undesired condition is detected at an output of the device, supplies a clamp enabling signal to the control terminal of a clamping transistor located between the input of the circuit and ground, and which, when enabled, prevents the turn-on voltage from increasing further, and so prevents the device from being turned on. | ||||||

| Control apparatus having two-fault tolerance for two position, motor operated actuators includes electronic circuitry for disconnection of the power return to the actuator motor armature thereby insuring that the motor will not be activated upon an inadvertent connection of power to either motor power input, and for indication of disconnection thereto. Testing determines the operatonal status of a motor relay and also determines inadvertent applications of power to the one of the pair of motor power inputs that is not connected to the power source through the position switch and one of the pair of limit switches.
