Abstract: A pressure measuring device/system that is capable of measuring the pressures of multiple systems in an automobile, including cylinder pressure, fuel pressure, transmission oil pressure, and engine oil pressure, and is capable of displaying and/or recording the measured pressure values remote from the device taking the measured remote pressures. The pressure measuring system has a remote interface and a sensor configured to communicate wirelessly with each other. The interface may be configured to be included within the device purpose built for displaying and interacting with the pressure values measured by the sensor. Additionally or alternatively, the interface may be configured to be downloaded as a mobile application “app” on a smartphone or other similar device.

Abstract: A convertible retaining ring pliers has a pivot, first and second jaws and first and second handles rotatably secured about the pivot. A pair of transfer pins is slidably disposed for selective movement in the jaws and the handles for establishing alternative operating positions enabling the jaws to move either inwardly or outwardly as the handles move inwardly. A switching mechanism is provided for simultaneous shifting of the transfer pins in the jaws and the handles. The switching mechanism includes reaction member housing assemblies which are mounted on opposite ends of the pivot and disposed on opposite external surfaces of the handles. A switchplate structure is rotatably mounted for side-to-side movement about the pivot, and is slidably positioned between at least one reaction member housing assembly and the external surface of one of the handles.
