| Number | Title | Issue Date |
| 7403837 | Portable device used to at least visualize the process data of a machine, a robot or a technical process A portable device (1) with at least one optical output device (2) for displaying at least process data of a machine, a robot or a technical process, with at least one input device (3) for at least intervening in the operating functions of the de... | 07/22/2008 |
| 7209330 | Reset lockout for circuit interrupting device Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechani... | 04/24/2007 |
| 6917856 | Robot It is constructed so as to detect a joint movement position of a robot arm by a position detector and a joint movement speed is calculated from change amounts of the joint movement position and elapsed time and is compared with an allowable movement speed and unlock... | 07/12/2005 |
| 6735534 | One or all phases recloser control A recloser trips on one phase for single-phase only fault conditions, or all phases for multi-phase fault conditions. During power delivery, the recloser monitors the three phases of a power line (e.g., phases A, B, and C). If a fault is detected on one phase, then ... | 05/11/2004 |
| 6735533 | Only picked up phases recloser control A recloser trips on one phase for single-phase only fault conditions, two phases for two-phase fault conditions, or all three phases for three-phase fault conditions. During power delivery, the recloser monitors the three phases of a power line (e.g., phases A, B, a... | 05/11/2004 |
| 6707655 | Adaptive protection for recloser control A recloser is adaptively controlled so that it will operate in a manner responsive to prevailing conditions such as time of day, day of week, and/or load current. A protection setting group is stored in a memory accessible by the recloser controller, and contains a ... | 03/16/2004 |
| 6657837 | Circuit breaker incorporating fault lockout protection Transformers (14) inject test voltage signals of know frequency to each phase of the load side of an electrical distribution circuit (15). Processor (32) waits for a delay period to allow transient effects of the injected signals to settle, and then accep... | 12/02/2003 |
| 6356806 | Method for handling a voltage drop in the control of a robot and for restarting a robot following a voltage drop A method for handling the voltage drop, at least in the control unit of a robot with a PC control is provided that minimizes the time of a plant stoppage and avoids wasteful process interruptions. The PC control has a real time operating system for the ti... | 03/12/2002 |
| 4931896 | Distribution line switchgear control with isolated cascaded power supplies A distribution line switchgear control which is particularly suitable for use with recloser switchgear which requires small amounts of power from the control for operation. The control is most usefully powered for continued operation by small amounts of l... | 06/05/1990 |
| 4860150 | Protector network for A-C equipment A power cutoff circuit is added to the protector network disclosed in U.S. Pat. No. 4,675,772 so that when an interruption in power occurs, at least one suppressor remains connected to a load even though a source is disconnected from the load. In one embo... | 08/22/1989 |
| 4857758 | Cycle timer for household appliance A hybrid analog and electronic cycle timer has a mechanical movement and cam-operated cycle switch driven by a low-RPM synchronous motor. Electronic control logic divides the power line frequency to obtain pulses for pulsing the synchronous motor. The con... | 08/15/1989 |
| 4709292 | Trouble detector apparatus for an air-conditioner including a counter and a timer A trouble detection apparatus for an air conditioner detects overcurrents occurring within a predetermined time period t2 which is a shortest time period necessary for stabilization of the compressor operation. By counting a number of occurrenc... | 11/24/1987 |
| 4703389 | Static trip circuit breaker with automatic circuit trimming Electronic trip units employed within static trip circuit breakers are individually calibrated and automatically adjusted to ensure that the trip transfer characteristics are within specification requirements. A trimming network within the trip unit circu... | 10/27/1987 |
| 4604674 | Reclosing relay apparatus A reclosing relay for reclosing a circuit breaker in an electrical power system. The reclosing relay is a multi-shot reclosing relay (i.e., providing more than one reclosure command to the circuit breaker) and includes primary and redundant lockout circui... | 08/05/1986 |
| 4454556 | Timing controller for a recloser relay A timing controller which supervises the reclosure of a fault responsive circuit breaker which includes a plurality of selectable switches for developing signals representing the reset and reclose delay times for the recloser relay operatively associated ... | 06/12/1984 |
| 4279007 | Single-phase fault detecting circuit breaker An electronic control system and associated circuit breaker is taught in which the effect of in-rush current on mining equipment, for example, in regard to tripping is minimized even though a single phase fault of an equal magnitude is adequately provided... | 07/14/1981 |
