Publication number: 20180172420Abstract: A sensor assembly includes a first magnetic field sensor that is a first type of sensor and has a first magnetic field sensitivity in a first primary sensing direction. The first primary sensing direction is along a longitudinal axis of the sensor assembly. The sensor assembly further includes a second magnetic field sensor that is a second type of sensor different than the first type of sensor and has a second magnetic field sensitivity in a second primary sensing direction that is less than the first magnetic field sensitivity. The second primary sensing direction is along a second axis that is different than the longitudinal axis.Type: ApplicationFiled: December 19, 2017Publication date: June 21, 2018Inventors: Matthew Hein, Daniel J.

Patent number: 9874611Abstract: A battery charger is disclosed that is configured to be connected to an external battery by way of external battery cables. In accordance with an important aspect of the invention, the battery charger is configured with automatic voltage detection which automatically determines the nominal voltage of the battery connected to its battery charger terminals and charges the battery as a function of the detected nominal voltage irrespective of the nominal voltage selected by a user. Various safeguards are built into the battery charger to avoid overcharging a battery. For battery chargers with user-selectable nominal battery voltage charging modes, battery charger is configured to over-ride a user-selected battery voltage mode if it detects that the battery connected to the battery charger terminals is different than the user-selected charging mode.Type: GrantFiled: November 15, 2016Date of Patent: January 23, 2018Assignee: Schumacher Electric CorporationInventors: John Whiting, Matthew A. Heins
