The mounting bracket affixes to a standard safety post or T-post and supports the electric fence monitor. The mounting bracket connects the electric fence monitor to earth ground via the T-post. The mounting bracket slips over a top of the T-post at a first angle relative to the T-post and locks onto the T-post at a second angle relative to the T-post. In one embodiment, the mounting bracket includes a fourth segment configured to provide a generally vertical mounting surface when mounted on a vertical T-post. | 10-22-2015 |
| 20150309089 | FAULT DETECTION DEVICE, FAULT DETECTION METHOD, AND PROGRAM - A fault detection device comprises: a measurement data acquirer that acquires measurement data for current flowing on power supply lines that are connected to multiple electrical devices; a clusterer that classifies the measurement data for a past fixed period into multiple clusters based on at least one of frequency and phase with respect to an AC cycle; a pattern analyzer that analyzes each of the clusters for an appearance pattern of measurement data that satisfy a preset standard; and a fault determiner that determines the occurrence of a fault when measurement data is acquired that differs from the analyzed appearance pattern. | 10-29-2015 |
| 20160033584 | METHOD OF FORMING A SEQUENCING SYSTEM AND STRUCTURE THEREFOR - In one embodiment, a sequencing system includes a plurality of integrated circuits connected in a daisy chain arrangement, where each integrated circuit has an LED load connection. The system includes a diagnostic circuit which signals to the control unit that an open circuit condition has been detected, thereby turning off all LED loads. | 02-04-2016 |

| 20220136319 | TESTER AND ELECTRICAL CONNECTORS FOR INSULATED GLASS UNITS - In some implementations, an apparatus for testing an insulated glass unit is provided. The apparatus includes a housing and a port coupled to the housing, where the port is configured to couple with a pigtail of an insulated glass unit. The apparatus includes a battery housed within the housing, where the battery is configured to provide power to an insulated glass unit. The apparatus includes an input interface which is coupled to the housing, where the input interface is configured to receive. The apparatus includes a controller which is housed within the housing and is configured to receive the input from the input interface, send commands to an insulated glass unit, and receive data from the insulated glass unit. The apparatus also includes one or more indicators coupled with the housing, where the one or more indicators are configured to indicate a status of the insulated glass unit. | 05-05-2022 |
