A test probe includes an electrically insulating handle, an electrically conducting blade extending from the handle, an electrically insulating shroud including a first portion and a second portion that are at least partially disposed around the electrically conducting blade. A housing is attached to the handle such that the first portion of the shroud is disposed within the housing, and the second portion of the shroud extends from an aperture formed in the housing. A spring disposed between the handle and the shroud biases the shroud toward the aperture formed in the housing. The shroud protects the electrically conducting blade from unintentional contact with a conductor during testing. When the test probe is correctly positioned on a device being tested, the shroud retracts into the housing exposing the electrically conducting blade. When the test probe is moved away from the device, the shroud returns to its original position.

Shrouded test probe

Exemplary embodiments provides a camera, having a first camera sub-assembly, a hub coupled to the first camera sub-assembly, a second camera sub-assembly coupled to the hub and rotatable relative thereto and a third camera sub-assembly coupled to the hub and rotatable relative thereto. The third camera sub-assembly can be in electrical communication with the first camera sub-assembly and/or the second camera sub-assembly via the hub. The hub can include a slot to guide electrical cable(s). Net torque acting on the camera can be zero such that one of the first rotational coupling or the second rotational coupling when rotated to a new position via an applied torque remains in the new position when the applied torque is released.

Diagnostic scope

An apparatus includes a chamber, a valve coupled to the chamber, a pump coupled to the chamber, a control circuit coupled to the pump, and a lever coupled to the valve, the pump, and the control circuit. Operation of the valve and the pump is controlled based on a position of the lever.
