| 20080231410 | RFID Open Fuse Indicator, System, and Method - Electrical fuse indicators used to detect when fuses enter an open state. Each fuse in an electrical system may be connected to a wireless identification element, which alerts a communication unit that the fuse has entered an open state. The wireless identification device may include an antenna. The antenna may be in contact with a fuse element, such that opening of the fuse element renders the antenna inoperable. Alternatively the antenna may be connected to the fuse element in such a manner that opening of the fuse element alters the frequency on which the antenna transmits. A logic port may also be used to detect the operational state of a fuse. Use of such indicators is compatible with existing infrastructure. | 09-25-2008 |
| 20090002119 | FUSE SENSING SCHEME - A fuse circuit includes a fuse configured for programming a configuration of an integrated circuit device and a resistive element having a known resistance value operably coupled in parallel with the fuse. The fuse and the resistive element form a parallel circuit configured for quickly sensing a state of the fuse in relation to the known value of the resistive element. In one embodiment, the device may further include a sense circuit operably coupled to the parallel circuit combination of the fuse and the resistive element. The sense circuit is configured to sense one of a FUSED state and an UNFUSED state of the fuse, for example, based on a comparison between a reference resistance and a FUSED resistance of the fuse when coupled to the known resistance. The fuse may comprise a programmable fuse, and the resistive element may comprise a MOS transistor. | 01-01-2009 |
| 20090045906 | MODERATELY HAZARDOUS ENVIRONMENT FUSE - A fuse for a moderately hazardous environment comprising includes: (i) a fuse element; (ii) first and second terminals connected to the fuse element; and (iii) a metal enclosure placed around the fuse element, the enclosure configured to protect the environment from an opening of the fuse element, and wherein the first and second terminals extend from the metal enclosure. | 02-19-2009 |
| 20110057760 | FUSE STATE INDICATOR SYSTEMS - Fuse state indicators for use with disconnect devices having a fuse are provided. Fuse state indicators include a housing having circuitry, a detecting means for detecting an open circuit condition, conductors adapted for electrical connection to a disconnect device so as to complete a circuit connecting the detecting means with a fuse of the disconnect device, and a signal transmitting means The detecting means is configured to transmit a signal to the signal transmitting means for determining an operational state of the fuse. The signal transmitting means, in turn, is configured to transmit a signal to a remote device the state of the fuse. | 03-10-2011 |
| 20120286922 | FUSIBLE LINK UNIT - A fusible link unit includes a conductive busbar, a resin housing, and a resin cover. The conductive busbar includes a fusible part. The resin housing is integrally formed at a predetermined position of the busbar. The resin cover is locked so as to cover an exposure window of the resin housing which is formed so that the fusible part is faced. The resin housing has an integral wall at the back position of the exposure window which faces the fusible part. | 11-15-2012 |
