Abstract: An auto-darkening eye protection apparatus such as a welding helmet includes an externally located combined push button and rotary switch coupled to lens control circuitry. A lens control setting display is configured on an internal portion of the apparatus and located in a field of view of a user when the lens is in a lowered operational position. The externally located combined push button and rotary switch is operable to select and adjust lens control parameters by a user wearing bulky hand protection such as welding gloves or welding mittens. The selection and adjustment level of the lens control parameters can be monitored on the display during the adjustment by a user while the lens is in the lowered operational position.

Abstract: Methods and systems involving a jack having removable and interchangeable saddles are disclosed for lifting vehicles and other items. The jack includes a saddle base having a retention member whereby the saddles can be interchanged for different vehicles or items without the use of special tools. For example, each saddle includes an engagement member having an indent therein for engagement with the retention member.

Abstract: A tire pressure monitoring tool transmits a triggering signal to a tire sensor; receives a reporting signal from the tire sensor; extracts data from the reporting signal; stores the extracted data; and transmits the stored data to an external device. The transmitted stored data is in a predetermined order, and in a text format.

Abstract: A dock has a cradle and at least one port for recharging and communicating with a tire pressure monitoring tool. The dock recognizes that the tool is inserted into the dock; evaluates the programming in the memory; compares the programming in the memory against programming stored in a computer; determines whether the programming in the memory is older than the programming stored in the computer; and if the programming in the memory is older than the programming in the computer, then loads the programming from the computer into the memory.

Abstract: An extensible ratcheting-type wrench head for imparting torque to a fastener having a plurality of sides. The wrench head comprises a lug aperture for mateably receiving a drive lug disposed on an extension handle.

Abstract: A ratchet wrench is provided which includes a handle having a head on the handle, a rotatable gear disposed in the head and having ratchet teeth, and a pivotable pawl engaged with the gear to allow ratcheting rotation of the gear in a first direction and prevent ratcheting rotation of the gear in a second direction. An obstruction is engageable with a cam surface at the base of the pawl in order to prevent the pawl from self-reversing.
