A technique for operating a power subsystem includes determining a respective power status of power devices in the power subsystem. The power devices include a first power device and a second power device that derives power from the first power device. Respective visual indicators of the first and second power devices are controlled to uniquely indicate which of the first and second power devices have an associated fault based on the respective power status of the power devices.

Techniques for indicating the status of power devices of a power subsystem

A technique for monitoring a passive element in a system includes determining, by a monitor, power supplied by a power supply coupled to the passive element and power consumed by a load coupled to the passive element. The monitor then determines power dissipated by the passive element based on the power supplied by the power supply and the power consumed by the load. The monitor initiates shut down of the power supply when the power dissipated by the passive element exceeds a threshold.

Techniques for monitoring passive elements in a system

An orthopaedic tool guide apparatus, including a tool member, a probe and, extending therebetween, a connecting structure, is arranged to enable adjustment of the positional relationship of the tool member to the probe over a range of positions in which the axis of the tool member remains aligned with the end of the probe. The connecting structure includes first and second arms hinged together at respective ends, the tool member connected to the first the arm and the probe being connected to the second the arm at positions spaced from the axis of the hinge, whereby one of the arms can be rotated relative to the other the arm through a series of different planes to enable the apparatus to be manuvered relative to the body. The axes of the hinge and the tool member are arranged to intersect at a predetermined target point, and the end of the probe is disposed at the target point.
