Operation of an insulated gate bipolar transistor (IGBT) is monitored by an apparatus that has a capacitor connected between a collector of the IGBT and an input node. A processing circuit, coupled to the input node, responds to current flowing through the capacitor by providing an indication whether a voltage level at the collector is changing and the rate of that change. The processing circuit also employs the capacitor current to provide an output voltage that indicates the voltage at the IGBT collector. |

A solenoid-driven automatic bus transfer switch may automatically transfer one or more electrical loads from a first power source to a second power source, or vice versa, in the event of a power failure or other casualty that affects either power source. The transfer switch may be operated in response to the energization of a solenoid coil, which causes a main shaft having a transfer element to rotate from being in contact with the first power source to being in contact with the second power source. The transfer element may be spring-mounted to the shaft, which ensures that a sufficient electrical contact exists between the surfaces of the transfer element and the respective leads of the first and second power sources, regardless of any wear or degradation that may be experienced at any of the surfaces. |

An automatic hold switch is disclosed. The automatic hold switch provides a means for automatically switching a hold feature on and off. When the hold feature is on, one or more input devices of a portable electronic device are disabled or prevented from providing input signals. When the hold feature is off, one or more input devices of a portable electronic device are enabled or allowed to provide input signals. Because the user no longer has to manually control the hold feature, the number of actions that need to be taken by the user is reduced. In one example, the automatic hold switch is embodied with light sensors that detect when the device is in a dark environment and when the device is in a light environment. A dark environment indicates to the portable electronic device that the user wishes not to input and therefore the hold feature is turned on. A lighted environment indicates to the portable electronic device that the user wishes to input and therefore the hold feature is turned off. |
